Describes functional foods for women's health (foods or food ingredients that provide health benefits beyond basic nutrition), explaining that both whole and modified foods can be included as functional foods. The paper discusses the history, regulation, and promotion of functional foods; consumer interest in functional foods; how to incorporate…
This article provides an overview of the procedures involved in scientific substantiation of functional food health claims in China. The definition of a functional food is discussed, in addition to the factors that led to its modification in 2005. The framework of administration includes the regulation of functional foods, steps involved in submission of dossiers, the safety control system for raw materials and products, and technical procedures for testing and evaluation. Scientific evidence required for a claim includes evidence from product tests in addition to evidence resulting from complete scientific literature searches relative to the food material or component in question. Currently, the 4 main rules for functional food assessment in China include 1) functional assessment procedures; 2) standard toxicological assessment; 3) regulations on nutrient supplements; and 4) standard analytical methods for functional components. The current situation for functional foods in China is analyzed, including a discussion of the distribution of the 27 currently allowed functional food health claims. The effectiveness of functional foods and health claims for improving health relies largely on the motivation and education of the public to be able to make good choices.

Functional foods have become increasingly popular with consumers anxious to mitigate the effects of an unhealthy lifestyle or aging. In spite of attractive health claims, these products do not have legal or regulatory status in most countries and are regulated through their health claims. Regulation of functional foods by health claims does not address health risks and adverse effects of these products. In this essay regulatory aspects of functional foods are reviewed along with adverse effects published in the peer-reviewed literature. We detail why the lack of an internationally accepted definition of functional foods places consumers at risk of adverse outcomes. Our review will assist regulatory agencies, manufacturers and consumer groups to assess the benefits and reduce the risks associated with these products.

New eating habits, actual trends in production and consumption have a health, environmental and social impact. The European Union is fighting diseases characteristic of a modern age, such as obesity, osteoporosis, cancer, diabetes, allergies and dental problems. Developed countries are also faced with problems relating to aging populations, high energy foods, and unbalanced diets. The potential of nutraceuticals/functional foods/food supplements in mitigating health problems, especially in the gastrointestinal (GI) tract, is discussed. Certain members of gut microflora (e.g., probiotic/protective strains) play a role in the host health due to its involvement in nutritional, immunologic and physiological functions. The potential mechanisms by which nutraceuticals/functional foods/food supplements may alter a host's health are also highlighted in this paper. The establishment of novel functional cell models of the GI and analytical tools that allow tests in controlled experiments are highly desired for gut research.

Two studies are reported, which aim to strengthen the scientific underpinning of strategic decisions regarding functional food development, as to (1) which health benefits to claim, (2) with which product (category), and (3) in which communication format. The first exploratory study is a secondary analysis of 10 different health claims systematically combined with 10 different food carriers to evaluate their combined suitability for functional food positioning. The results show that consumers tend to prefer functional food concepts that primarily communicate disease-related health benefits in carriers with a healthy image or health positioning history. Study 2 examines health claim format and systematically varies the way in which specific health benefits are being communicated to the consumer. Two physiologically oriented claims (heart disease and osteoporosis) and two psychologically oriented food claims (stress and lack of energy) are expressed in enhanced function format versus disease risk reduction format. Also, it includes the individual difference variable of 'regulatory focus' and the health status of the respondent to explore how these factors impact health claim evaluation. The results show that consumer evaluations primarily differ to the extent that health claims are personally relevant in addressing an experienced disease state. Framing is important, but its effect differs by health benefit. No strong effects for consumers' regulatory focus were found. Underlying mechanisms of these effects and their implications for the development of functional foods are discussed.
Genome analysis using next generation sequencing technologies has revolutionized the characterization of lactic acid bacteria and complete genomes of all major groups are now available. Comparative genomics has provided new insights into the natural and laboratory evolution of lactic acid bacteria and their environmental interactions. Moreover, functional genomics approaches have been used to understand the response of lactic acid bacteria to their environment. The results have been instrumental in understanding the adaptation of lactic acid bacteria in artisanal and industrial food fermentations as well as their interactions with the human host. Collectively, this has led to a detailed analysis of genes involved in colonization, persistence, interaction and signaling towards to the human host and its health. Finally, massive parallel genome re-sequencing has provided new opportunities in applied genomics, specifically in the characterization of novel non-GMO strains that have potential to be used in the food industry. Here, we provide an overview of the state of the art of these functional genomics approaches and their impact in understanding, applying and designing lactic acid bacteria for food and health.

The functional food industry is expanding, yet research into consumer perceptions of functional foods is limited. Older adults could benefit from functional foods due to age-related food and health issues. This research gathered information about functional foods from community-dwelling older adults (n = 200) who completed a researcher-administered questionnaire about consumption, food matrices, bioactive ingredients, and health areas addressed through functional foods. Overall prevalence of functional food consumption was found to be 93.0%. Commonly consumed foods included yogurt with probiotics (56.0%), eggs with omega-3 fatty acids (37.0%), and bread with fiber (35.5%). Functional food matrices primarily consumed were yogurt (51.5%), bread (44.0%), and cereal (40.0%). The primary functional food bioactive consumed was dietary fiber (79.5%). Most participants (86.2%) indicated that they consume functional foods to improve health, and the major areas specified were osteoporosis/bone health (67.5%), heart disease (61.0%), and arthritis (55.0%). These results inform health professionals regarding the potential of functional foods to support health among older adults.

As an adjunct to cancer treatment, the use of health functional foods (HFFs) seems to be increasing. However, little is known for the use of HFFs among cancer patients in Korea. The aims of this study were to investigate the exposure rate of HFF use among gastrointestinal (GI) cancer patients and to examine the relationship of socio-demographic and disease-related characteristics with the use of HFFs. A total of 126 patients diagnosed with GI cancer participated in the study. A cross-sectional survey was conducted using a questionnaire. Over a half of all the patients surveyed (n = 67; 53.2%) used HFFs. Patients who were younger, had higher income, or longer duration of disease showed a trend to use HFFs more frequently, even though the tendency was not statistically significant. The most commonly used HFF was vitamin complex (n = 20; 16%), followed by red ginseng (n = 15; 12%), and sweet wormwood (Artemisia annua) (n = 11; 8.8%). About 26% of all responders expressed concerns for using HFFs. The primary concern was 'going against physician's recommendations' (36.8%). About 63% of respondents expressed a desire to consult with their physicians and follow their recommendations. More basic scientific data and educational materials regarding HFFs are required for both health-care professionals and cancer patients. A larger sample and size-controlled groups representing each cancer type will continue to be recruited for participation in this survey.

Eggs are sources of protein, fats and micronutrients that play an important role in basic nutrition. However, eggs are traditionally associated with adverse factors in human health, mainly due to their cholesterol content. Nowadays, however, it is known that the response of cholesterol in human serum levels to dietary cholesterol consumption depends on several factors, such as ethnicity, genetic makeup, hormonal factors and the nutritional status of the consumer. Additionally, in recent decades, there has been an increasing demand for functional foods, which is expected to continue to increase in the future, owing to their capacity to decrease the risks of some diseases and socio-demographic factors such as the increase in life expectancy. This work offers a brief overview of the advantages and disadvantages of egg consumption and the potential market of functional eggs, and it explores the possibilities of the development of functional eggs by technological methods.

Health is an important motivation for the consumption of both organic and functional foods. The aim of this study was to clarify to what extent the consumption of organic and functional foods are characterized by a healthier lifestyle and a higher level of well-being. Moreover, the influence of social desirability on the respondents' response behavior was of interest and was also analyzed. Well-being and health was measured in a sample of 555 German consumers at two levels: the cognitive-emotional and the behavioral level. The results show that although health is an important aspect for both functional food and organic food consumption, these two forms of consumption were influenced by different understandings of health: organic food consumption is influenced by an overall holistic healthy lifestyle including a healthy diet and sport, while functional food consumption is characterized by small "adjustments" to lifestyle to enhance health and to increase psychological well-being. An overlap between the consumption of organic and functional food was also observed. This study provides information which enables a better characterization of the consumption of functional food and organic food in terms of well-being and health.

The aim of the present study was to survey attitudes to and use of functional foods and to investigate which demographic variables and attitudes to diet and health predict consumption of functional foods among Swedish consumers. A questionnaire was developed and sent to 2000 randomly selected Swedish citizens aged between 17 and 75 years. A total of 972 (48%) responded, 53% were female and 44% male. Mean age was 45 years. The results revealed that 84% of respondents were familiar with the concept of functional foods; 83% had consumed/purchased at least one of the seven functional food products presented in the questionnaire. Of those who had consumed a functional food, 25% had perceived effect of it. Positive correlations were seen between consumers perceiving a personal reward from eating functional foods, having an interest in natural products and an interest in general health. Consumption/purchase of functional foods was related to beliefs in the effects of the products, having consumed nutraceuticals or dietary supplements, having a diet-related problem personally or in the family, and a high level of education. The characteristic Swedish functional food consumer has a high level of education, is health-conscious and interested in healthy foods and believes in the health effect of functional foods. Thus, factors other than demographics better explain consumption of FF. However, the study population may represent a more health-conscious segment of the Swedish population in general. Additional studies are therefore required to elucidate the attitudes and use of FF in different consumer groups.

'Functional Food' is not a new concept but it became more important recently due to the collapse of most social health system because 'Functional Foods' allow low cost prevention of numerous diseases. 'Functional Foods' are different from 'Neutraceuticals' which remain drug based with poor taste whereas 'Functional Foods' remain good food which could be consumed for years, but in addition have a disease prophylactic function. They are becoming particularly important for the prevention of food allergy in 'at risk' population, obesity, osteoporosis, cardiovascular diseases and particularly high blood pressure and atherosclerosis, but also for cancer prevention. The newest trend is that governments and health authorities allow food manufacturers to make health prevention related claims on mass media.

The philosophy that food can be health promoting beyond its nutritional value is gaining acceptance. Known disease preventive aspects of nutrition have led to a new science, the 'functional food science'. Functional foods, first introduced in Japan, have no universally accepted definition but can be described as foods or food ingredients that may provide health benefits and prevent diseases. Currently, there is a growing interest in these products. However, not all regulatory issues have been settled yet. Five categories of foods can be classified as functional foods: dietary fibers, vitamins and minerals, bioactive substances, fatty acids and pro-, pre- and symbiotics. The latter are currently the main focus of research. Functional foods can be applied in pediatrics: during pregnancy, nutrition is 'functional' since it has prenatal influences on the intra-uterine development of the baby, after birth, 'functional' human milk supports adequate growth of infants and pro- and prebiotics can modulate the flora composition and as such confer certain health advantages. Functional foods have also been studied in pediatric diseases. The severity of necrotising enterocolitis (NEC), diarrhea, irritable bowel syndrome, intestinal allergy and lactose intolerance may be reduced by using functional foods. Functional foods have proven to be valuable contributors to the improvement of health and the prevention of diseases in pediatric populations.
The Japanese scientific academic community defined 'functional food' early in the 1980s. That is, functional foods are those that have three functions. The primary function is nutrition. The secondary function is a sensory function or sensory satisfaction. The third is the tertiary function, which is physiological. The Japanese Ministry of Health, Labour, and Welfare (MHLW) set up 'Foods for Specified Health Use' (FOSHU) in 1991 as a regulatory system to approve the statements made on food labels concerning the effect of the food on the human body. Food products applying for approval by FOSHU are scientifically evaluated in terms of their effectiveness and safety by the Council of Pharmaceutical Affairs and Food Hygiene under the MHLW. The regulatory range of FOSHU was broadened in 2001 to accept the forms of capsules and tablets in addition to those of conventional foods. FOSHU increased the total to about 330 items in January 2003. The MHLW enacted a new regulatory system, 'Foods with Health Claims', in April 2001, which consists of the existing FOSHU system and the newly established 'Foods with Nutrient Function Claims' (FNFC). Under the FNFC, twelve vitamins (vitamins A, B1, B2, B6, B12, C, E, D, biotin, pantothenic acid, folic acid, and niacin) and two minerals (Ca and Fe) are standardized. Examples of claims regarding these substances are as follows: 'Calcium is a nutrient which is necessary to form bones and teeth'; 'Vitamin D is a nutrient which promotes calcium absorption in the gut intestine and aids in the formation of bones.' The upper and lower levels of the daily consumption of these nutrients are also determined. The labelling of functional foods should always be based on scientific evidence and be in harmony with international standards. The nutrient-function claim was adopted in the guidelines for nutrition claims by the Codex Alimentarius in 1997. The claims of the Japanese FNFC are equivalent to the nutrient function claims standardized by the

Functional foods stand for a new category of remarkably promising foods bearing properties (i.e., low cholesterol, antioxidant, anti-aging, anticancer, etc.) that have already rendered them quite appealing. There are many classes offunctionalfoods (pro- and pre-biotics, dietary fiber, low fat, etc.), and their definition is occasionally confused with that of nutraceuticals and novel foods. Consumers' main skepticism regarding functional foods resides in the veracity of health claims and in the low and often inadequate control of their claimed properties. Legislation concerning this matter is progressing at an extremely low pace and currently only Japan, the U.K., U.S.A., and Scandinavian countries have managed to make notable progress. Moreover, the labeling of functional foods is far from informative, providing scanty information about nutritional value, storage, and cooking recipes. It is anticipated that technological advances in the food industry, in conjunction with extensive clinical trials and governmental control, will eventually guarantee the credibility of health claims and ensure consumers' confidence in functional foods.

The main objective of this survey is to reveal the relationship between lifestyle, health behavior, and the consumption of functional foods on the basis of Grunert's food-related lifestyle model. In order to achieve this objective, a nationwide representative questionnaire-based survey was launched with 1000 participants in Hungary. The results indicate that a Hungarian consumer makes rational decisions, he or she seeks bargains, and he wants to know whether or not he gets good value for his money. Further on, various lifestyle segments are defined by the authors: the rational, uninvolved, conservative, careless, and adventurous consumer segments. Among these, consumers with a rational approach provide the primary target group for the functional food market, where health consciousness and moderate price sensitivity can be observed together. Adventurous food consumers stand out because they search for novelty; this makes them an equally important target group. Conservative consumers are another, one characterized by positive health behavior. According to the findings of the research, there is a significant relationship between lifestyle, health behavior, and the preference for functional food products.

Functional foods are foods with positive health effects that extend beyond their nutritional value. They affect the function of the body and help in the management of specific health conditions. Green tea, a time-honoured Chinese herb, might be regarded as a functional food because of its inherent anti-oxidant, anti-inflammatory, antimicrobial and antimutagenic properties. They are attributed to its reservoir of polyphenols, particularly the catechin, epigallocatechin-3-gallate. Owing to these beneficial actions, this traditional beverage was used in the management of chronic systemic diseases including cancer. Recently, it has been emphasized that the host immuno-inflammatory reactions destroy the oral tissues to a greater extent than the microbial activity alone. Green tea with its wide spectrum of activities could be a healthy alternative for controlling these damaging reactions seen in oral diseases, specifically, chronic periodontitis, dental caries and oral cancer, which are a common occurrence in the elderly population.

As widely acknowledged functional foods (FFs) may contribute to improve human health due to the presence of specific components useful for their protective action against several diseases. However it is essential that consumers are able to comprehend and assess the properties of FFs health claims play a central role in helping consumers to select among food alternatives, beyond providing protection against unsupported or misleading statements about foods properties. At the same time health claims are the main marketing tool that the food industry could use to differentiate FFs from other products. Clearly, massive investments in research and development are necessary to enter the FF market segment, together with the possibility to protect innovation through patents. Current paper aims to examine factors influencing consumer understanding and use of food health claims on FFs, as well as providing several indications for developers, marketers and policy makers. After a brief review of the literature the results of a quantitative survey conducted online on 650 Italian consumers are presented. Results show that consumer use and understanding of health claims on FFs depend on different variables such as socio-demographic characteristics, knowledge and confidence with nutrition information but also wording and variables related specifically to the product. Furthermore, different segments with a diverse degree of use and understanding of health claims have been identified. Therefore, to boost market growth, more efforts are needed by policy makers and marketers to provide better information on nutrition and health aspects of FF using an approach capable to ensure truthful, significant and clear information. Finally some recent patents related to the FFs market with specific regard to components and/or functionality investigated in the current paper are reviewed.

The Canadian Food and Drugs Act and Regulations, through its definitions of food and drug, currently restricts health-related claims for foods, food ingredients, and natural health products (NHPs). Over the past few decades, scientific research has led to a large body of information that demonstrates the benefits for health of many food and NHP ingredients. Health Canada recognized the constraints of the current regulatory environment and started to develop regulations related to the allowance of health claims for functional foods and NHPs, including those foods and NHPs that would contain conjugated linoleic acid isomers. Health Canada has 3 initiatives under way in the area of health claims for foods: 1) to adopt the generic health claims of the United States within a Canadian context, 2) to develop scientific standards of evidence and a guidance document for supporting the validity of product-specific claims, and 3) to develop an overall regulatory framework for functional foods. In 2000, Health Canada announced approval for the use of 5 generic diet-related health claims: sodium and hypertension, calcium and osteoporosis, saturated and trans fat and cholesterol and coronary artery disease, fruits and vegetables and cancer, and sugar alcohols and dental caries. Under a separate initiative, Natural Health Products Regulations were published in the Canada Gazette Part II on June 18, 2003. The NHP Regulations came into force on January 1, 2004, with a transition period ranging from 2 y (for site licensing) to 6 y (for product licensing, for products already issued a drug identification number).

Functional foods can be considered to be those whole, fortified, enriched or enhanced foods that provide health benefits beyond the provision of essential nutrients (e.g., vitamins and minerals), when they are consumed at efficacious levels as part of a varied diet on a regular basis. Linking the consumption of functional foods or food ingredients with health claims should be based on sound scientific evidence, with the "gold standard" being replicated, randomized, placebo-controlled, intervention trials in human subjects. However, not all foods on the market today that are claimed to be functional foods are supported by enough solid data to merit such claims. This review categorizes a variety of functional foods according to the type of evidence supporting their functionality, the strength of that evidence and the recommended intakes. Functional foods represent one of the most intensively investigated and widely promoted areas in the food and nutrition sciences today. However, it must be emphasized that these foods and ingredients are not magic bullets or panaceas for poor health habits. Diet is only one aspect of a comprehensive approach to good health.

The effect of psychological stress on health is becoming a serious concern, with figures from the World Health Organization showing that stress-related disorders affect nearly 450 million individuals worldwide. Heightened physiological stress responses and psychosocial factors have been linked to disease pathways such as hypertension and CVD. This has prompted significant interest within the scientific community, public health bodies and industry to employ interventions to control and reduce the impact of stress on health. There is now strong potential for functional foods to offer stress management benefits. Various physiological pathways have been targeted by specific dietary supplements for stress reduction, including the hypothalamic-pituitary-adrenal axis and sympathetic nervous system. Presently there are a number of ingredients, which include vitamin C, milk proteins, a number of herbal extracts (ginkgo biloba, ginseng, kava, valerian and lemon balm), and n-3 fatty acids, that have demonstrated potential stress reactivity-lowering and mood-enhancing effects, although further work is required to substantiate the efficacy in human subjects. Dietary supplements that can alleviate excessive stress responses may play an increasingly important role for the maintenance of health in a stressful environment. However, future research should employ a greater range of measures that will provide stronger evidence to substantiate functional food claims for stress relief.
Functional foods marketed as promoting health or reducing the risk of disease open a promising avenue for consumers to pursue a healthier life. Despite the stable growth in functional foods in Taiwan, at present little is known about whether or not consumers with varying degrees of health consciousness and different healthy lifestyles will have dissimilar attitudes toward functional foods and will vary in their willingness to use them. Regression analysis of this empirical study verifies that consumers' attitudes toward functional foods do have an impact on their willingness to use such foods. Moreover, moderated regression analysis (MRA) reveals that the joint moderator of health consciousness and healthy lifestyle indeed exerts an impact on consumers' willingness to consume functional foods. Finally, one-way ANOVA tests show that there are some differences between the consumers of the "Healthy Life Attentive" group and those of the "Healthy Life Inattentive" one both in attitudes toward and in willingness to consume functional foods. The empirical results and findings from this study would be valuable for the marketers in the functional food industry to formulate marketing communication strategies and facilitate this industry's development.

During long-duration NASA space missions, such as proposed missions to Mars, astronauts may experience negative physiological effects such as bone loss. Functional foods such as high-lycopene, high-flavonoids and high-omega-3 products and fruits and vegetables may mitigate the negative effects of spaceflight on physiological factors including the bone health of crewmembers. Previous studies showed that current ISS provisions provide high-lycopene and high-omega-3 food items but the variety is limited, which could promote menu fatigue. Bioactive compounds can degrade like other chemical compounds and lose functionality. The native concentrations and stability of bioactive compounds have never been determined in spaceflight foods, and adequate information is not available for commercial products for the storage durations required for space exploration (5 years). The purpose of this task is to develop new spaceflight foods that are high in omega-3 fatty acids, lycopene, or flavonoids, identify commercial products with these bioactive compounds that meet spaceflight requirements, and define the stability of these nutrients in storage to enable purposeful functional food incorporation into the space food system. The impact of storage temperature on the stability of lutein, lycopene, beta-carotene, omega-3 fatty acids, phenolics, anthocyanins and sterols is being studied in 12 ISS menu items stored at three different temperatures (4, 21, 35 degree C) over 2 years. Additionally, nutrient and quality stability are being assessed on a larger food set stored at 21 degree C over 2 years that contains twelve newly developed foods, 10 commercial products repackaged to spaceflight requirements, and another 5 current ISS menu items expected to be good sources of omega-3 fatty acids, lycopene, or flavonoids. All items were shipped overnight to the Linus Pauling Institute at Oregon State University (Corvalis, OR) after processing and 1-year of storage and analyzed for bioactive

Recent advances in intestinal microbiota research are the background for the appearance of functional foods. Lactic fermentation products are included in the functional foods and classified into 3 groups based on their mechanisms of action: probiotics, prebiotics and biogenics. Probiotics are viable microorganisms, such as lactobacilli and bifidobacteria, that beneficially affect the host by improving the intestinal bacterial balance. Prebiotics are nondigestible food ingredients, such as oligosaccharides and dietary fiber, that beneficially affect the host by selectively stimulating the growth or activities of beneficial intestinal bacteria in the colon and thus improve the health of the hosts. Biogenics are biologically active peptides, including immunopotentiators (biological response modifier: BRM), plant flavonoids, etc. They act directly or indirectly through modulation of intestinal microbiota on the health of the hosts. Thus, functional foods enhance bioregulation such as stresses, appetite and absorption; biodefence, such as immunity and suppression of allergies; prevent diseases, including diarrhea, constipation, cancer, cholesterolemia and diabetes; and suppress aging through immunostimulation as well as suppression of mutagenesis, carcinogenesis, oxidation processes, intestinal putrefaction, and cholesterolemia.

Macroalgae have for centuries been consumed whole among the East Asian populations of China, Korea, and Japan. Due to the environment in which they grow, macroalgae produce unique and interesting biologically active compounds. Protein can account for up to 47% of the dry weight of macroalgae depending on species and time of cultivation and harvest. Peptides derived from marcoalgae are proven to have hypotensive effects in the human circulatory system. Hypertension is one of the major, yet controllable, risk factors in cardiovascular disease (CVD). CVD is the main cause of death in Europe, accounting for over 4.3 million deaths each year. In the United States it affects one in three individuals. Hypotensive peptides derived from marine and other sources have already been incorporated into functional foods such as beverages and soups. The purpose of this review is to highlight the potential of heart health peptides from macroalgae and to discuss the feasibility of expanding the variety of foods these peptides may be used in.

The terms 'nutraceuticals' and 'dietary or food supplements' are not very popular in Japan as compared to most of other countries. However, the concept of 'functional foods', which benefits the structure and function of the human body, is known as a result of research studies initiated on the health benefits of foods in 1984. The Ministry of Education organized a national research and development project to evaluate the functionalities of various foods. Researchers from diverse scientific fields succeeded to define new functions of food, successfully incorporating the previously recognized functions of nutrition, sensory/satisfaction and physiological effects of ingredients in foods. Some of the food manufacturers and distributors unfortunately capitalized on such food functionalities to promote 'health foods' by claiming drug-like effects and violating laws. In 1991, the Ministry of Health and Welfare (MHW) now as the Ministry of Health, Labor and Welfare (MHLW) introduced a 'foods for specified health uses' (FOSHU) system, for the control of such exaggerated and misleading claims. The other reason for such enforcement is due to an increase in the population of elderly people and lifestyle-related diseases that include obesity, diabetes mellitus, high blood pressure, cerebro- and cardiovascular diseases and cancer. In 2001, a new regulatory system, 'foods with health claims' (FHC) with a 'foods with nutrient function claims' (FNFC) system and newly established FOSHU was introduced. In addition, MHLW has changed the existing FOSHU, FNFC and other systems in 2005. Such changes include the new subsystems of FOSHU such as (1) standardized FOSHU, (2) qualified FOSHU and (3) disease risk reduction claims for FOSHU. In the present chapter, two guidelines that require good manufacturing practice (GMP) and self-investigative systems for ensuring the safety of raw materials used for products in the dosage forms such as capsules, tablets, etc. have been discussed

Quinoa (Chenopodium quinoa Willd., Amaranthaceae) is a grain-like, stress-tolerant food crop that has provided subsistence, nutrition, and medicine for Andean indigenous cultures for thousands of years. Quinoa contains a high content of health-beneficial phytochemicals, including amino acids, fiber, polyunsaturated fatty acids, vitamins, minerals, saponins, phytosterols, phytoecdysteroids, phenolics, betalains, and glycine betaine. Over the past 2 decades, numerous food and nutraceutical products and processes have been developed from quinoa. Furthermore, 4 clinical studies have demonstrated that quinoa supplementation exerts significant, positive effects on metabolic, cardiovascular, and gastrointestinal health in humans. However, vast challenges and opportunities remain within the scientific, agricultural, and development sectors to optimize quinoa's role in the promotion of global human health and nutrition.

Functional microorganisms and health benefits represent a binomial with great potential for fermented functional foods. The health benefits of fermented functional foods are expressed either directly through the interactions of ingested live microorganisms with the host (probiotic effect) or indirectly as the result of the ingestion of microbial metabolites synthesized during fermentation (biogenic effect). Since the importance of high viability for probiotic effect, two major options are currently pursued for improving it--to enhance bacterial stress response and to use alternative products for incorporating probiotics (e.g., ice cream, cheeses, cereals, fruit juices, vegetables, and soy beans). Further, it seems that quorum sensing signal molecules released by probiotics may interact with human epithelial cells from intestine thus modulating several physiological functions. Under optimal processing conditions, functional microorganisms contribute to food functionality through their enzyme portfolio and the release of metabolites. Overproduction of free amino acids and vitamins are two classical examples. Besides, bioactive compounds (e.g., peptides, γ-amino butyric acid, and conjugated linoleic acid) may be released during food processing above the physiological threshold and they may exert various in vivo health benefits. Functional microorganisms are even more used in novel strategies for decreasing phenomenon of food intolerance (e.g., gluten intolerance) and allergy. By a critical approach, this review will aim at showing the potential of functional microorganisms for the quality of functional foods.
The goal of the Functional Food Science in Europe (FUFOSE) concerted action was to reach consensus on scientific concepts of functional foods in Europe by using the science base that supports evidence that specific nutrients positively affect physiological functions. The outcome proposes "a working definition" of functional foods: foods can be regarded as functional if they can be satisfactorily demonstrated to affect beneficially one or more target functions in the body, beyond adequate nutritional effects, in a way relevant to an improved state of health and well-being and/or reduction of risk of disease. Functional foods must remain foods and they must achieve their effects in amounts normally consumed in a diet. Evidence from human studies, based on markers relating to biological response or on intermediate endpoint markers of disease, could provide a sound scientific basis for messages and claims about the functional food products. Two types of claims are proposed that relate directly to these two categories of markers: Enhanced function claims (type A) and reduced risk of disease claims (type B). A new EU Concerted Action will start with, and build upon, the principles defined within FUFOSE. This project PASSCLAIM will (i) produce a consensus on principles for the scientific substantiation of health-related claims for food and food components, (ii) select common criteria for how markers should be identified, validated and used in well-designed studies to explore the links between diet and health and (iii) to evaluate critically the existing schemes which assess the scientific substantiation of claims.

Objectives This study was performed to provide a reference base for suggesting proper guidelines for the health of the people by analyzing perception and intake pattern on health functional foods and by identifying needs in pre- and postmenopausal women. Methods We conducted a self-administered survey in women admitted to the Department of Obstetrics and Gynecology at a university hospital between July and August, 2014. The survey questionnaire consisted of 8 items on general characteristics, 4 items on awareness on health functional foods, and 16 items on usage status. Results Of all 133 women with ages ranging between 19 to 67 years, postmenopausal women were 57 accounting for 42.9% of all subjects. Mean age was 55.4 ± 6.2 and menopausal age was 49.6 ± 4.3 in the postmenopause group. Mean age was 38.7 ± 9.0 in the postmenopause group. With respect to components of health functional foods, 76.3% of women answered "important" in the postmenopause group, significantly higher than 49.1% in the postmenopause group (P < 0.01). In regard to price, those who answered "important" accounted for the largest percentage in the premenopausal group at 56.6%, and those who answered "moderately important" accounted for 57.9% in the postmenopausal women. A significant difference was found between the two groups (P < 0.05). Conclusion Development of products reflecting consumer needs can be considered. It is important to foster an environment allowing individuals to choose right health functional foods and further studies are warranted. PMID:27152310
Many functional requirements are met by the use of simple and complex carbohydrates in food. Carbohydrates offer a wide range of rheological and other properties, including solubility, cryoprotection, sweetening effect, hygroscopicity, crystallization inhibition, flavor encapsulation, and coating ability. These properties are based on chemical structure and interactions with other molecules through hydrogen bonding, ionic effect, and the formation of complexes with lipids and proteins. The ability to understand these properties directly affects the development of food products and processes. Thus, the functionality of carbohydrates in foods integrates precise knowledge of chemical structure and behavior with practical applications in the development and preparation of foods.

Conjugated linoleic acid (CLA) has drawn significant attention since the 1980s for its various biological activities. CLA consists mainly of two isomers, cis-9,trans-11 and trans-10,cis-12, and the mixture of these two (CLA mix or 50:50) has been approved for food as GRAS (generally recognized as safe) in the United States since 2008. Along with its original discovery as an anticancer component, CLA has been shown to prevent the development of atherosclerosis, reduce body fat while improving lean body mass, and modulate immune and/or inflammatory responses. This review summarizes the clinical trials involving CLA since 2012; additional uses of CLA for age-associated health issues are discussed; and CLA's potential health concerns, including glucose homeostasis, oxidative stress, hepatic steatosis, and milk-fat depression, are examined. With ongoing applications to food products, CLA consumption is expected to rise and close monitoring of not only its efficacy but also its known and unknown consequences are required to ensure proper applications of CLA.

Liking of a particular food after repeated consumption may be reduced, limiting the effectiveness of health-functional foods requiring on-going consumption to deliver their benefits. This study examined the effect of repeated consumption of foods containing the novel ingredient, Australian sweet lupin (Lupinus angustifolius) kernel fibre (LKFibre) on sensory acceptability in the dietary intervention setting. In a single-blind randomised crossover 4-week intervention, participants consumed both control and equivalent LKFibre-containing products daily on separate interventions separated by a 4-week period on habitual diet. Seven products: muesli, bread, muffin, chocolate brownie, chocolate milk drink, pasta and instant mashed potato were assessed twice (days 4 and 18 of intervention), by 38 participants for appearance, texture, flavour and general acceptability using a structured graphic hedonic scale. Overall the results showed there was no reduction (P=0.594) in general acceptability of LKFibre foods after repeated consumption, suggesting potential for long-term consumption. The control food products were however generally preferred (P<0.001) over the LKFibre foods; the mean difference for general acceptability between being <6% (0.82cm) of the 15cm hedonic scale used, suggesting LKF addition did not severely affect product palatability.

Starchy roots and tuber crops play a pivotal role in the human diet. There are number of roots and tubers which make an extensive biodiversity even within the same geographical location. Thus, they add variety to the diet in addition to offering numerous desirable nutritional and health benefits such as antioxidative, hypoglycemic, hypocholesterolemic, antimicrobial, and immunomodulatory activities. A number of bioactive constituents such as phenolic compounds, saponins, bioactive proteins, glycoalkaloids, and phytic acids are responsible for the observed effects. Many starchy tuber crops, except the common potatoes, sweet potatoes, and cassava, are not yet fully explored for their nutritional and health benefits. In Asian countries, some edible tubers are also used as traditional medicinal. A variety of foods can be prepared using tubers and they may also be used in industrial applications. Processing may affect the bioactivities of constituent compounds. Tubers have an immense potential as functional foods and nutraceutical ingredients to be explored in disease risk reduction and wellness. PMID:27127779

Modern nutritional science is providing ever more information on the functions and mechanisms of specific food components in health promotion and/or disease prevention. In response to demands from increasingly health conscious consumers, the global trend is for food industries to translate nutritional information into consumer reality by developing food products that provide not only superior sensory appeal but also nutritional and health benefits. Today's busy life styles are also driving the development of healthy convenience foods. Recent innovations in food technologies have led to the use of many traditional technologies, such as fermentation, extraction, encapsulation, fat replacement, and enzyme technology, to produce new health food ingredients, reduce or remove undesirable food components, add specific nutrient or functional ingredients, modify food compositions, mask undesirable flavors or stabilize ingredients. Modern biotechnology has even revolutionized the way foods are created. Recent discoveries in gene science are making it possible to manipulate the components in natural foods. In combination with biofermentation, desirable natural compounds can now be produced in large amounts at a low cost and with little environmental impact. Nanotechnology is also beginning to find potential applications in the area of food and agriculture. Although the use of new technologies in the production of health foods is often a cause for concern, the possibility that innovative food technology will allow us to produce a wide variety of food with enhanced flavor and texture, while at the same time conferring multiple health benefits on the consumer, is very exciting.

Sea-food processing wastes and underutilized species of fish are a potential source of functional and bioactive compounds. A large number of bioactive substances can be produced through enzyme-mediated hydrolysis. Suitable enzymes and the appropriate bioreactor system are needed to incubate the waste materials. Membrane separation is a useful technique to extract, concentrate, separate or fractionate the compounds. The use of membrane bioreactors to integrate a reaction vessel with a membrane separation unit is emerging as a beneficial method for producing bioactive materials such as peptides, chitooligosaccharides and polyunsaturated fatty acids from diverse seafood-related wastes. These bioactive compounds from membrane bioreactor technology show diverse biological activities such as antihypertensive, antimicrobial, antitumor, anticoagulant, antioxidant and radical scavenging properties. This review discusses the application of membrane bioreactor technology for the production of value-added functional materials from sea-food processing wastes and their biological activities in relation to health benefits.

The term "functional food" refers to foods or ingredients of foods providing an additional physiological benefit beyond their basic nutritional needs. Health benefits are best obtained through a varied diet containing fruits, vegetables, grains, legumes and seeds. However, fortified foods and dietary supplements have been marketed and food industry have made functional food one of their current leading trends. Recently, the number of functional foods that have a potential benefit on health has hugely grown and scientific evidence is supporting the role of functional foods in prevention and treatment of several diseases. Cancer, diabetes, heart disease and hypertension are the most important diseases that can be treated or prevented by functional foods; other diseases are osteoporosis, abnormal bowel motility, and arthritis. It has been estimated that 80% of cancer in USA have a nutrition/diet component suggesting a great impact of functional food and foods components on incidence and treatment of cancer. Numerous factors complicate the evaluation of scientific evidence such as the complexity of food substance, effect on food, metabolic changes associated to dietary changes, the lack of biological markers of disease development. This paper reviews the scientific evidence supporting this area regarding only those foods and ingredients in which a clear experimental and clinical evidence exists for their chemopreventive and therapeutic effects.

Almost fifty million people are food insecure in the United States, which makes food insecurity one of the nation's leading health and nutrition issues. We examine recent research evidence of the health consequences of food insecurity for children, nonsenior adults, and seniors in the United States. For context, we first provide an overview of how food insecurity is measured in the country, followed by a presentation of recent trends in the prevalence of food insecurity. Then we present a survey of selected recent research that examined the association between food insecurity and health outcomes. We show that the literature has consistently found food insecurity to be negatively associated with health. For example, after confounding risk factors were controlled for, studies found that food-insecure children are at least twice as likely to report being in fair or poor health and at least 1.4 times more likely to have asthma, compared to food-secure children; and food-insecure seniors have limitations in activities of daily living comparable to those of food-secure seniors fourteen years older. The Supplemental Nutrition Assistance Program (SNAP) substantially reduces the prevalence of food insecurity and thus is critical to reducing negative health outcomes.

In Japan the onset of lifestyle-related diseases has increased, the people interests in "food and health", and the movement of the food industry is actively to respond to it. Healthy life expectancy is essential for mitigation of social medical expenses and improvement of the personal QOL in the super-aged society. Daily diet becomes the nucleus of healthy life expectancy. Historically, the concept of "functional food" system was born in the mid-1980s in ahead of our country in the world. Administration as a response to it to allow on that review, "food for specified health uses" was born. Furthermore, foods with a prevention function of lifestyle-related diseases, such as "Foods with Function Claims" system have been developing from 2015. In this paper, we want to further describe these circumstances, the current situation and the outlook.

Functional foods are increasing in popularity owing to their ability to confer health and physiological benefits. Nevertheless, the notion that functional foods improve health when providing nutrients at levels above and beyond existing recommended intakes is inconsistent with the definition of requirement. This disparity highlights the need for an alternative definition of nutrient requirement. The present objective is to examine distinctions between optimization of health, as defined by what we currently deem as required intakes, versus adding physiological benefit using bioactive agents found in functional foods. Presently, requirement is defined as the lowest amount of intake of a nutrient that will maintain a defined level of nourishment for a specific indicator of adequacy. In contrast, functional foods are described as ingredients that are not necessary for body function, yet provide added physiological benefit that confer better overall health. Plant sterols are one example of such an ingredient. Plant sterols lower plasma cholesterol concentrations, and may thus be considered essential nutrients in physiological situations where circulating cholesterol concentrations are high. Similarly, intakes of omega-3 fats beyond existing requirement may confer additional health benefits such as hypolipidemic and anti-diabetic effects. These examples underscore the inconsistencies between what is defined as a nutrient requirement versus what is identified as a health benefit of a functional food. Such discrepancies emphasize the need for a more all-encompassing definition of a nutrient requirement; that is, one that moves beyond the prevention of overt deficiency to encompass improved health and disease risk reduction.

The methanolic extract of Cassia hirsuta L. seed materials, an underutilized food legume collected from India, was analyzed for antioxidant activity and health relevant functionality. The methanolic extract of raw seeds contained a total free phenolic content of 15.82 ± 1.69 g catechin equivalent/100 g extract DM. Encouraging levels of ferric reducing/antioxidant power (FRAP, 1,446 mmol Fe[II]/mg extract), inhibition of ß-carotene degradation (48.81%) and scavenging activity against DPPH (64.40%) and superoxide (43.78%) radicals were exhibited by the raw samples. Further, 83.11% of α-amylase and 62.79% of α-glucosidase enzyme inhibition characteristics under in vitro starch digestion bioassay were also recorded. Sprouting + oil-frying caused an apparent increase on the total free phenolic content and a significant improvement in the antioxidant and free radical scavenging capacity of methanolic extract of C. hirsuta seeds, while soaking + cooking as well as open-pan roasting treatments showed diminishing effects. The analysis of the phenolic profile revealed the presence of gallic acid, p-coumaric acid and (+)-catechin in the methanolic extract of these seeds.

Current spaceflight foods were evaluated to determine if their nutrient profile supports positioning as a functional food and if the stability of the bioactive compound within the food matrix over an extended shelf-life correlated with the expected storage duration during the mission. Specifically, the research aims were: Aim A. To determine the amount of each nutrient in representative spaceflight foods immediately after processing and at predetermined storage time to establish the current nutritional state. Aim B. To identify the requirements to develop foods that stabilize these nutrients such that required concentrations are maintained in the space food system throughout long duration missions (up to five years). Aim C. To coordinate collaborations with health and performance groups that may require functional foods as a countermeasure.

All foods are functional at some physiological level, but it is the position of the American Dietetic Association (ADA) that functional foods that include whole foods and fortified, enriched, or enhanced foods have a potentially beneficial effect on health when consumed as part of a varied diet on a regular basis, at effective levels. ADA supports research to further define the health benefits and risks of individual functional foods and their physiologically active components. Health claims on food products, including functional foods, should be based on the significant scientific agreement standard of evidence and ADA supports label claims based on such strong scientific substantiation. Food and nutrition professionals will continue to work with the food industry, allied health professionals, the government, the scientific community, and the media to ensure that the public has accurate information regarding functional foods and thus should continue to educate themselves on this emerging area of food and nutrition science. Knowledge of the role of physiologically active food components, from plant, animal, and microbial food sources, has changed the role of diet in health. Functional foods have evolved as food and nutrition science has advanced beyond the treatment of deficiency syndromes to reduction of disease risk and health promotion. This position paper reviews the definition of functional foods, their regulation, and the scientific evidence supporting this evolving area of food and nutrition. Foods can no longer be evaluated only in terms of macronutrient and micronutrient content alone. Analyzing the content of other physiologically active components and evaluating their role in health promotion will be necessary. The availability of health-promoting functional foods in the US diet has the potential to help ensure a healthier population. However, each functional food should be evaluated on the basis of scientific evidence to ensure appropriate integration

It is the position of the Academy of Nutrition and Dietetics to recognize that although all foods provide some level of physiological function, the term functional foods is defined as whole foods along with fortified, enriched, or enhanced foods that have a potentially beneficial effect on health when consumed as part of a varied diet on a regular basis at effective levels based on significant standards of evidence. The Academy supports Food and Drug Administration-approved health claims on food labels when based on rigorous scientific substantiation. All food is essentially functional at some level as it provides energy and nutrients needed to sustain life. However, there is growing evidence that some food components, not considered nutrients in the traditional sense, may provide positive health benefits. Foods containing these food components are called functional foods. Functional food research holds many promises for improving the quality of life for consumers; however, to achieve such outcomes, scientific research must effectively establish the bioavailability and efficacy of these compounds at levels that are physiologically achievable under typical dietary patterns. This Position Paper reviews the complexities of defining functional foods; categories of foods marketed as functional; regulation of functional foods; the scientific substantiation of and advancement of functional food research; as well as a message to registered dietitians and dietetic technicians, registered, on how to remain current in their knowledge of functional food research and the translation of this information to consumers.

The health and wellness of human beings is largely dictated by the consumption of nutritious foods. Various studies have linked foods as helpful in combating a number of degenerative diseases; as such, a lot of research on functional attributes linked directly to the health benefits of various plant and animal foods have been witnessed in recent years. Although vast number of naturally occurring health-enhancing substances are of plant origin, there are a number of physiologically active components in animal products as well that deserve attention for their potential role in optimal health. Consumption of biologically active ingredients in fruits and vegetables has been linked to help combat diseases such as cancer, cardiovascular diseases, obesity, and gastrointestinal tract disorders. Lot of research is required to substantiate the potential health benefits of those foods for which the diet-health relationships are not sufficiently validated, and create a strong scientific knowledge base for proper application of naturally present foods in combating various diseases and disorders.

Bioactive compounds in foods have been gaining interest, and processes to consider them for public health recommendations are being discussed. However, the evidence base is difficult to assemble. It is difficult to demonstrate causality, and there often is not a single compound-single effect relation. Furthermore, health benefits may be due to metabolites produced by the host or gut microbiome rather than the food constituent per se. Properties that can be measured in a food may not translate to in vivo health effects. Compounds that are being pursued may increase gut microbial diversity, improve endothelial function, improve cognitive function, reduce bone loss, and so forth. A new type of bioactive component is emerging from epigenetic modifications by our diet, including microRNA transfer from our diet, which can regulate expression of human genes. Policy processes are needed to establish the level of evidence needed to determine dietary advice and policy recommendations and to set research agendas.

Human health and diseases are determined by many complex factors. Health threats from the human-animal-ecosystems interface (HAEI) and zoonotic diseases (zoonoses) impose an increasing risk continuously to public health, from those emerging pathogens transmitted through contact with animals, food, water and contaminated environments. Immense challenges forced on the ecological perspectives on food and the eco-environments, including aquaculture, agriculture and the entire food systems. Impacts of food and eco-environments on human health will be examined amongst the importance of human interventions for intended purposes in lowering the adverse effects on the biodiversity. The complexity of relevant conditions defined as factors contributing to the ecological determinants of health will be illuminated from different perspectives based on concepts, citations, examples and models, in conjunction with harmful consequential effects of human-induced disturbances to our environments and food systems, together with the burdens from ecosystem disruption, environmental hazards and loss of ecosystem functions. The eco-health literacy should be further promoting under the "One Health" vision, with "One World" concept under Ecological Public Health Model for sustaining our environments and the planet earth for all beings, which is coincidentally echoing Confucian's theory for the environmental ethics of ecological harmony.
The goals of Norwegian food and nutrition policy are that food should not only be nutritionally adequate and safe, it should also be produced in a sustainable way. This implies a change towards food produced according to principles of organic agriculture. The issue discussed here is whether organic food is also better in terms of nutritional adequacy. A review of existing literature reveals that organic foods compared to conventionally produced foods seem to have a higher content of antioxidants in plant products and a higher content of fat-soluble vitamins and omega-3 fatty acids in animal products. Animal studies (among them, on rabbits and chickens) show higher fertility and less morbidity in animals fed organically. Furthermore, when given a choice, animals prefer organic to conventionally produced fodder. It is not possible to draw conclusions from these studies on health effects on humans. So far there have been no controlled studies in humans that have assessed such effects, though a higher content of antioxidants have been found in the urine of subjects put on an organic diet. In summary, a change to an organic diet may have a direct positive health effect on humans, as well as an indirect effect through a healthier environment.

To stimulate discussion around the topic of ‘carbohydrates’ and health, the Brazilian branch of the International Life Sciences Institute held the 11th International Functional Foods Workshop (1–2 December 2011) in which consolidated knowledge and recent scientific advances specific to the relationship between carbohydrates and health were presented. As part of this meeting, several key points related to dietary fiber, glycemic response, fructose, and impacts on satiety, cognition, mood, and gut microbiota were realized: 1) there is a need for global harmonization of a science-based fiber definition; 2) low-glycemic index foods can be used to modulate the postprandial glycemic response and may affect diabetes and cardiovascular outcomes; 3) carbohydrate type may influence satiety and satiation; glycemic load and glycemic index show links to memory, mood, and concentration; 4) validated biomarkers are needed to demonstrate the known prebiotic effect of carbohydrates; 5) negative effects of fructose are not evident when human data are systematically reviewed; 6) new research indicates that diet strongly influences the microbiome; and 7) there is mounting evidence that the intestinal microbiota has the ability to impact the gut–brain axis. Overall, there is much promise for development of functional foods that impact the microbiome and other factors relevant to health, including glycemic response (glycemic index/glycemic load), satiety, mood, cognition, and weight management.

Anthocyanins, a proanthocyanidin-type of flavonoid, contain an abundance of functional phytochemicals and occur in fruits such as cranberry, blueberry, orange, apple and in vegetables such as tomato, sweet pepper, spinach, and radishes. Functional and essential diets have been ingested in daily life since the primitive era of history. When anthocyanins are coupled with some water-soluble sugar molecules, their color becomes red, yellow, violet, or blue. It is very intriguing that anthocyanins provide the colorful variety of pigments for pansies, petunias, plums, and other diverse flowers. Chlorophyll in various fruits and vegetables is the main green phyto-component, while anthocyanins are probably the most important visible plant pigments in the natural kingdom having specific colors. Anthocyanins have been clinically used in many folklore medicines worldwide. Anthocyanins could provide health benefits for age-related diseases as well as other diseases. Anthocyanins have higher antioxidant capacity against oxidative stress induced by excess reactive oxygen species (ROS) such as superoxide radicals, hydrogen peroxide, and thus the human body might be protected from oxidative injury by anthocyanins. On the basis of these facts, we review the synthesis of plant flavonoids and their ability to scavenge oxidants, inhibit or activate enzymes, and the safety of proanthocyanidins and anthocyanidins present in common foods.

Astronauts face numerous health challenges during long-duration space missions, including diminished immunity, bone loss and increased risk of radiation-induced carcinogenesis. Changes in the intestinal flora of astronauts may contribute to these problems. Soy-based fermented food products could provide a nutritional strategy to help alleviate these challenges by incorporating beneficial lactic acid bacteria, while reaping the benefits of soy isoflavones. We carried out strain selection for the development of soy ferments, selecting strains of lactic acid bacteria showing the most effective growth and fermentation ability in soy milk ( Streptococcus thermophilus ST5, Bifidobacterium longum R0175 and Lactobacillus helveticus R0052). Immunomodulatory bioactivity of selected ferments was assessed using an in vitro challenge system with human intestinal epithelial and macrophage cell lines, and selected ferments show the ability to down-regulate production of the pro-inflammatory cytokine interleukin-8 following challenge with tumour necrosis factor-alpha. The impact of fermentation on vitamin B1 and B6 levels and on isoflavone biotransformation to agluconic forms was also assessed, with strain variation-dependent biotransformation ability detected. Overall this suggests that probiotic bacteria can be successfully utilized to develop soy-based fermented products targeted against health problems associated with long-term space travel.

The term "food allergy" is widely misused for all sorts of symptoms and diseases caused by food. Food allergy (FA) is an adverse reaction to food (food hypersensitivity) occurring in susceptible individuals, which is mediated by a classical immune mechanism specific for the food itself. The best established mechanism in FA is due to the presence of IgE antibodies against the offending food. Food intolerance (FI) are all non-immune-mediated adverse reactions to food. The subgroups of FI are enzymatic (e.g. lactose intolerance due to lactase deficiency), pharmacological (reactions against biogenic amines, histamine intolerance), and undefined food intolerance (e.g. against some food additives). The diagnosis of an IgE-mediated FA is made by a carefully taken case history, supported by the demonstration of an IgE sensitization either by skin prick tests or by in vitro tests, and confirmed by positive oral provocation. For scientific purposes the only accepted test for the confirmation of FA/FI is a properly performed double-blind, placebo-controlled food challenge (DBPCFC). A panel of recombinant allergens, produced as single allergenic molecules, may in future improve the diagnosis of IgE-mediated FA. Due to a lack of causal treatment possibilities, the elimination of the culprit "food allergen" from the diet is the only therapeutic option for patients with real food allergy.
The continued appearance of scientific evidence about the role of diet and/or its components in health and wellness, has favored the emergence of functional foods which currently constitute one of the chief factors driving the development of new products. The application of multiple emulsions opens new possibilities in the design and development of functional foods. Multiple emulsions can be used as an intermediate product (food ingredient) into technological strategies normally used in the optimization of the presence of bioactive compounds in healthy and functional foods. This paper presents a summary of the types, characteristics and formation of multiple emulsions, possible location of bioactive compounds and their potential application in the design and preparation of healthy and functional foods. Such applications are manifested particularly relevant in relation to quantitative and qualitative aspects of lipid material (reduced fat/calories and optimization of fatty acid profile), encapsulation of bioactive compounds mainly hydrophilic and sodium reduction. This strategy offers interesting possibilities regarding masking flavours and improving sensory characteristics of foods.

Due to constant health awareness and readily available information on usefulness of different diet and their direct link with health, the demand of functional food is increasing day by day. The concept of functional foods includes foods or food ingredients that exert a beneficial effect on host health and/or reduce the risk of chronic disease beyond basic nutritional functions. Increasing awareness of consumer health and interest in functional foods to achieve a healthy lifestyle has resulted in the need for food products with versatile health-benefiting properties. Cereal- and cereal component-based food products offer opportunities to include probiotics, prebiotics, and fibers in the human diet. Various growth studies using probiotic Lactic acid bacteria on cereal-based substrates and utilization of whole grain or components as high-fiber foods in developing novel food products lend support to the idea that cereal-based media may well be good probiotic carriers. It is essential that science and traditional knowledge should go together to find mutually beneficial results. In the Indian subcontinent, making use of fermented food and beverages using local food crops and other biological resources are very common. But the nature of the products and the base material vary from region to region.
Food insecurity is associated with nutrient inadequacy and a variety of unfavorable health outcomes. However, little is known about whether food security is associated with lower cognitive function in the elderly. We investigated the prevalence of food insecurity in a representative sample of 1358 P...

The United States has set a national goal to eliminate health disparities. This article emphasizes the importance of food systems in generating and exacerbating health disparities in the United States and suggests avenues for reducing them. It presents a conceptual model showing how broad food system conditions interplay with community food environments—and how these relationships are filtered and refracted through prisms of social disparities to generate and exacerbate health disparities. Interactions with demand factors in the social environment are described. The article also highlights the separate food systems pathway to health disparities via environmental and occupational health effects of agriculture. PMID:23173027

The importance of safety and functionality analysis of foodstuffs and raw materials is supported by national legislations and European Union (EU) directives concerning not only the amount of residues of pollutants and pathogens but also the activity and content of food additives and the health claims stated on their labels. In addition, consumers' awareness of the impact of functional foods' on their well-being and their desire for daily healthcare without the intake pharmaceuticals has immensely in recent years. Within this picture, the availability of fast, reliable, low cost control systems to measure the content and the quality of food additives and nutrients with health claims becomes mandatory, to be used by producers, consumers and the governmental bodies in charge of the legal supervision of such matters. This review aims at describing the most important methods and tools used for food analysis, starting with the classical methods (e.g., gas-chromatography GC, high performance liquid chromatography HPLC) and moving to the use of biosensors-novel biological material-based equipments. Four types of bio-sensors, among others, the novel photosynthetic proteins-based devices which are more promising and common in food analysis applications, are reviewed. A particular highlight on biosensors for the emerging market of functional foods is given and the most widely applied functional components are reviewed with a comprehensive analysis of papers published in the last three years; this report discusses recent trends for sensitive, fast, repeatable and cheap measurements, focused on the detection of vitamins, folate (folic acid), zinc (Zn), iron (Fe), calcium (Ca), fatty acids (in particular Omega 3), phytosterols and phytochemicals. A final market overview emphasizes some practical aspects ofbiosensor applications.

Food insecurity, the lack of consistent access to sufficient quality and quantity of food, affects an estimated 800 million people around the world. Although household food insecurity is generally associated with poor child nutrition and health in the USA, we know less about household food insecurity and child health in developing countries. Particularly lacking is research assessing how associations between household food insecurity and children's health outcomes may differ by child age and among children beyond age 5 years in low-income settings. We use data from a population-based sample of households with children ages 3-11 years (N = 431) in León, Nicaragua to consider how household food insecurity is associated with three measures of child health: illness, anaemia and low height-for-age. Our results provide new evidence that even mild household food insecurity is detrimental to children's health; and that child age conditions the associations between household food insecurity and child health. We find that food insecurity is especially harmful to health during early childhood, but continues to have significant associations with health into middle childhood (up to ages 7-8 years). We discuss the potential implications of these results for future child health research and policies in low-income countries. © 2016 John Wiley & Sons Ltd.

In recent years there is a growing interest in food and food ingredient which may provide health benefits. Food as well as food ingredients containing health-preserving components, are not considered conventional food, but can be defined as functional food. To characterise such foods, as well as nutraceuticals specific, high sensitive and reproducible analytical methodologies are needed. In light of this importance we set out to develop innovative HPLC methods employing reversed phase narrow bore column and high-performance anion-exchange chromatographic methods coupled with pulsed amperometric detection (HPAEC-PAD), which are specific for carbohydrate analysis. The developed methods were applied for the separation and quantification of citrus flavonoids and to characterize fructooligosaccharide (FOS) and fructans added to functional foods and nutraceuticals.

Much nutrition policy is nutrient-based, supported by extensive nutrient science and food nutrient composition tables and recommendations for dietary evaluation. There are no comparable instruments for food structure. This constitutes a policy and practice gap since food is valued for its textural properties and not simply its chemistry. The structurally-important 'dietary fibre' at first proved of greater interest for its chemistry than its physico-chemistry even to health scientists and workers. As food chemistry became evidently complex, especially for phytonutrients, food-based dietary guidelines became an imperative and were launched by FAO and WHO in Cyprus in 1995. Food-health relationships, after weaning, are best articulated in terms of the achievement of dietary diversity, predicated partly on how intact foods are or in what way they are prepared. Cooking itself has health-promoting characteristics. Even with identical chemistry, food structure makes a major difference to biological and health outcomes. With evidence that food structure contributes to the matrix that food provides for nutrient delivery, and also to gut microbiomic profile and integrity, concern has grown about overly-processed food and health outcomes. The definition and categorisation of 'ultra-processed foods' is now a work-in-progress. Future public health nutritional and clinical nutrition developments will take account of food structure. To these ends, food composition tables will need to provide information like particle size and viscosity. Dietary recommendations will need to take account of food structure, as is the case for Brazil whose first step is "Make natural or minimally processed foods the basis of your diet".

Inulin is a water soluble storage polysaccharide and belongs to a group of non-digestible carbohydrates called fructans. Inulin has attained the GRAS status in USA and is extensively available in about 36,000 species of plants, amongst, chicory roots are considered as the richest source of inulin. Commonly, inulin is used as a prebiotic, fat replacer, sugar replacer, texture modifier and for the development of functional foods in order to improve health due to its beneficial role in gastric health. This review provides a deep insight about its production, physicochemical properties, role in combating various kinds of metabolic and diet related diseases and utilization as a functional ingredient in novel product development.

More than 600 functional non-nutrient food factors (FFFs) in vegetables and fruits are considered to be effective for health promotion and disease prevention. However, phytochemicals studied thus far have failed to yield predicted results in randomized intervention studies. To assess the health effects of phytochemicals, a breakthrough in epidemiological methods was necessary. We constructed a database of non-nutrient FFFs to estimate the chemical classes and total amount of FFF-intake in order to facilitate estimation and calculation for nutritional research. So far, flavonoids, terpenoids, carotenoids, and sulfur compounds are included in our FFF database. We calculated the intake of various phytochemicals per capita from 79 subjects' dietary records by FFF database, and estimated that subjects ingested more than 10 micromole per day of phytochemicals such as catechin, isoflavones, isothiocyanate, ferulic acid, quercetin, cinnamic acid and chlorogenic acid. Chief component analysis yielded 12 factors (80%), of which only a few factors showed negative associations with serum cholesterol and LDL concentration. Many factors showed adverse relationships with liver function and serum triacylglycerol concentration. Weekly self-reported daily dietary records including name of dish, constituent foods and their amounts were separately collected for 6 months and analyzed in Kyoto women. Seasonal changes of phytochemical intake showed significant variation according to the seasonal consumption of fruits and vegetables. Lycopene increased in the summer due to watermelon and tomato intake in this season. Seasonal variation of FFF was quite large compared to the variation of macro- and micronutrients. Careful evaluation of the effects of FFF intake on health is necessary, especially when supplements are also consumed. The most effective combinations of FFF intake for human health could be elucidated by using our FFF-DB in conjunction with population-based cohort studies.

Our symposium entitled, "Food Insecurity and Health across the Lifespan" explored the latest research from the economic, medical, pediatric, geriatric, and nutrition literature concerning the measurement, prevalence, predictors, and consequences of food insecurity across the lifespan, with a focus on chronic disease, chronic disease management, and healthcare costs. Consideration of the health impacts of food insecurity is a new and timely area of research, with a considerable potential for translation of the findings into public policy surrounding alleviation of food insecurity. Although it is widely acknowledged that food insecurity and hunger are morally unacceptable, strategies to develop national policies to alleviate hunger must also approach this problem by considering the economic impact of food insecurity on health and well-being. The goals of this symposium were to: 1) learn about the prevalence and severity of food insecurity in the US across the lifespan and how this is increasing with the continued economic downturn; 2) understand the growing body of research that documents the impact of varying degrees of food insecurity on physical and mental health across the lifespan; 3) examine how food insecurity is related to chronic disease; and 4) explore research methodology to determine the impact of food insecurity on healthcare costs and utilization. Our symposium provided new and novel understandings and research initiatives directed toward alleviating food insecurity in America.

Health is intrinsic to human security (HumS) although it is somewhat anthropocentric and about our own psychosocial and biomedical status more than various external threats. The 1994 United Nations Development Program definition of HumS includes economic, food, environmental, personal, community and political security with freedom from fear and want. Environmental factors are critical for health security (HealS), especially with widespread socio-economic difficulty, and health systems less affordable or accessible. The nexus between nutritionally-related disorders and infectious disease is the most pervasive world health problem. Most if not all of the Millennium Development Goals are food-linked. Maternal nutrition has life-long health effects on the yet-to-be born child. The mix of essential nutrient deprivation and energy imbalance is rife across many societies. Food systems require deeper understanding and governance to overcome these food-related health risks which are matters of food security (FoodS). Nutritionally-related Disability Adjusted Life Years (DALYS) are improving markedly in many parts of the world, along with poverty and hunger reduction and health system advances. But recent economic, energy, food, water, climate change and health crises along with conflict are limiting. It is time for international and regional understanding of how households and communities can collectively manage these threats in affordable and sustainable ways. There is untapped problem-solving capacity at the international local level if supported by combined food--health systems expertise, innovation, infrastructure and governance. Principles of equity and ethics must apply. The Food in Health Security (FIHS) roundtable aims to develop a Network to facilitate this process.

The authors examine the impact of urbanization on food security and human health in the Middle East. Within-urban-population disparities in food security represent one of the most dramatic indicators of economic and health disparities. These disparities are reflected in a double burden of health outcomes: increasing levels of chronic disease as well as growing numbers of undernourished among the urban poor. These require further comprehensive solutions. Some of the factors leading to food insecurity are an overdependence on purchased food commodities, lack of sufficient livelihoods, rapid reductions in peripheral agricultural land, and adverse impacts of climate change. The Food and Agriculture Organization of the United Nations (FAO) Food Security Framework is used to examine and compare 2 cities in the Middle East: Amman, Jordan, and Manama, Bahrain.

Peak oil is the phenomenon whereby global oil supplies will peak, then decline, with extraction growing increasingly costly. Today's globalized industrial food system depends on oil for fueling farm machinery, producing pesticides, and transporting goods. Biofuels production links oil prices to food prices. We examined food system vulnerability to rising oil prices and the public health consequences. In the short term, high food prices harm food security and equity. Over time, high prices will force the entire food system to adapt. Strong preparation and advance investment may mitigate the extent of dislocation and hunger. Certain social and policy changes could smooth adaptation; public health has an essential role in promoting a proactive, smart, and equitable transition that increases resilience and enables adequate food for all.

Fermented foods and beverages were among the first processed food products consumed by humans. The production of foods such as yogurt and cultured milk, wine and beer, sauerkraut and kimchi, and fermented sausage were initially valued because of their improved shelf life, safety, and organoleptic properties. It is increasingly understood that fermented foods can also have enhanced nutritional and functional properties due to transformation of substrates and formation of bioactive or bioavailable end-products. Many fermented foods also contain living microorganisms of which some are genetically similar to strains used as probiotics. Although only a limited number of clinical studies on fermented foods have been performed, there is evidence that these foods provide health benefits well-beyond the starting food materials.

Public health nutrition sits at the nexus of a global crisis in food, environmental and health systems that has generated - along with numerous other problems - an urgent and changing problem of food insecurity. The 'new' food insecurity, however, is different from the old: it is bimodal, encompassing issues of both under- and over-consumption, hunger and obesity, quantity and quality; it has assumed a decidedly urban dimension; and it implicates rich and poor countries alike. The complexity of the expressions of this challenge requires new approaches to public health nutrition and food policy that privilege systemic, structural and environmental factors over individual and mechanistic ones. In this context, the current paper argues that school food systems rise with buoyant potential as promising intervention sites: they are poised to address both modes of the food security crisis; integrate systemic, structural and environmental with behavioural approaches; and comprise far-reaching, system-wide efforts that influence the wider functioning of the food system. Based on a discussion of Bogotá and other pioneering policies that explicitly aim to create a broader food system with long-term foundations for good public health and food security, the paper suggests a new research and action agenda that gives special attention to school food in urban contexts.

The health benefits of plant food-based diets could be related to both integrated antioxidant and antiinflammatory mechanisms exerted by a wide array of phytochemicals present in fruit, vegetables, herbs and spices. Therefore, there is mounting interest in identifying foods, food extracts and phytochemical formulations from plant sources which are able to efficiently modulate oxidative and inflammatory stress to prevent diet-related diseases. This paper reviews available evidence about the effect of supplementation with selected fruits, vegetables, herbs, spices and their extracts or galenic formulation on combined markers of redox and inflammatory status in humans.

There are numerous reports that show the benefits on the health attributed to the probiotic consumptions. Most of the studies were performed using animal models and only some of them were validated in controlled human trials. The present review is divided in two sections. In the first section we describe how the probiotic microorganisms can interact with the intestinal epithelial cells that are the first line of cell in the mucosal site, focusing in the studies of two probiotic strains: Lactobacillus casei DN-114001 (actually Lactobacillus paracasei CNCMI-1518) and Lactobacillus casei CRL 431. Then we describe same beneficial effects attributed to probiotic administration and the administration of fermented milks containing these microorganisms or potential probiotic yoghurt, principally on the immune system and on the intestinal barrier in different experimental mouse models like enteropathogenic infection, malnutrition, cancer and intestinal inflammation.

There are several ways to present nutritional health messages, particularly pyramidic indices, but they have many deficiencies such as lack of agreement on a unified or clear methodology for food grouping and ignoring nutritional group inter-relation and integration. This causes confusion for health educators and target individuals. This paper presents an Arabian food pyramid that aims to unify the bases of nutritional health messages, bringing together the function, contents, source and nutritional group servings and indicating the inter-relation and integration of nutritional groups. This provides comprehensive, integrated, simple and flexible health messages.

Organic foods are promoted as superior and safer options for today's health-conscious consumer. Manufacturers of organic food claim it to be pesticide-free and better in terms of micronutrients. Consumers have to pay heavily for these products--and they are willing to--provided they are assured of the claimed advantages. Scientific data proving the health benefits of organic foods, especially in children, are lacking. Indian Government has developed strict guidelines and certification procedures to keep a check on manufacturers in this financially attractive market. American Academy of Pediatrics, in its recently issued guidelines, did not recommend organic foods over conventional food for children. Indian Academy of Pediatrics has not opined on this issue till date. In this perspective, we present a critical review of production and marketing of organic foods, and scientific evidence pertaining to their merits and demerits, with special reference to pediatric population.

Plant phenolics as secondary metabolites are key to a plant's defense response against biotic and abiotic stresses. These phytochemicals are also increasingly relevant to food preservation and human health in terms of chronic disease management. Phenolic compounds from different food crops with different chemical structures and biological functions have the potential to act as natural antioxidants. Plant-based human foods are rich with these phenolic phytochemicals and can be used effectively for food preservation and bioactive enrichments through metabolic stimulation of key pathways. Phenolic metabolites protect against microbial degradation of plant-based foods during postharvest storage. Phenolics not only provide biotic protection but also help to counter biochemical and physical food deteriorations and to enhance shelf life and nutritional quality. This review summarizes the role of metabolically stimulated plant phenolics in food preservation and their impact on the prevention of oxidative stress-induced human diseases.

The results of food science investigations have confirmed the relationship between the type of eaten food and health. Simultaneously, consumers are paying more and more attention to the kind of food they eat, as their awareness concerning the influence of proper food on health is increasing. On that base the conception of functional food has been created. This kind of food, besides being a source of essential macro- and micronutrients, exerts an additional positive influence on health. Probiotics and prebiotics containing products are a good example of functional food. These products provide not only essential nutrients but also microorganisms and polysaccharides, which are indigestible in the human alimentary tract, but exert a positive effect on human health. It may be a therapeutic or prophylactic effect due to specific affliction or may improve health in general. The paper - based on available literature - shows a positive influence of probiotics and prebiotics on human health, especially in the immunomodulation effect, an advantageous effect on the digestive system, antitumor activity and a possible therapeutic and prophylactic effect on cardiovascular diseases and obesity.

Tibetan nomads have lived since ancient times in the unique and harsh environment of the Qinghai-Tibetan Plateau with average altitudes over 4000 m. These people have been able to live and multiply healthily over numerous generations under the extreme stress of high-altitude environment, including cold, hypoxia, and strong ultraviolet radiation, and with a simple diet devoid of vegetables and fruits for most of the year. Their survival depends heavily on yak milk, and its products comprise the main portion of their daily diet. In this review, yak milk and its derived products are examined in detail and compared with milk from other ruminant species. Yak milk products seem to be particularly rich in functional and bioactive components, which may play a role in maintaining the health status of Tibetan nomads. This includes particular profiles of amino acids and fatty acids, and high levels of antioxidant vitamins, specific enzymes, and bacteria with probiotic activity (yoghurt is the main food). Based on that, it is proposed that the Tibetan nomads have developed a nutritional mechanism adapted to cope with the specific challenges posed by the environment of the world's highest plateau. Systematic studies are required to demonstrate this in a more mechanistic way.

Peanut is an important crop grown worldwide. Commercially it is used mainly for oil production but apart from oil, the by-products of peanut contains many other functional compounds like proteins, fibers, polyphenols, antioxidants, vitamins and minerals which can be added as a functional ingredient into many processed foods. Recently it has also revealed that peanuts are excellent source of compounds like resveratrol, phenolic acids, flavonoids and phytosterols that block the absorption of cholesterol from diet. It is also a good source of Co-enzyme Q10 and contains all the 20 amino acids with highest amount of arginine. These bioactive compounds have been recognized for having disease preventive properties and are thought to promote longevity. The processing methods like roasting and boiling have shown increase in the concentration of these bioactive compounds. In the present paper an overview on peanut bioactive constituents and their health benefits are presented.

A food (ingredient) is regarded as functional if it is satisfactorily demonstrated to affect beneficially 1 or more target functions in the body beyond adequate nutritional effects. The term inulin-type fructans covers all beta(2<--1) linear fructans including native inulin (DP 2-60, DP(av) = 12), oligofructose (DP 2-8, DP(av) = 4), and inulin HP (DP 10-60, DP(av) = 25) as well as Synergy 1, a specific combination of oligofructose and inulin HP. Inulin-type fructans resist digestion and function as dietary fiber improving bowel habits. But, unlike most dietary fibers, their colonic fermentation is selective, thus causing significant changes in the composition of the gut microflora with increased and reduced numbers of potentially health-promoting bacteria and potentially harmful species, respectively. Both oligofructose and inulin act in this way and thus are prebiotic: they also induce changes in the colonic epithelium and in miscellaneous colonic functions. In particular, the claim "inulin-type fructans enhance calcium and magnesium absorption" is scientifically substantiated, and the most active product is oligofructose-enriched inulin (Synergy 1). A series of studies furthermore demonstrate that inulin-type fructans modulate the secretion of gastrointestinal peptides involved in appetite regulation as well as lipid metabolism. Moreover, a large number of animal studies and preliminary human data show that inulin-type fructans reduce the risk of colon carcinogenesis and improve the management of inflammatory bowel diseases. Inulin-type fructans are thus functional food ingredients that are eligible for enhanced function claims, but, as more human data become available, risk reduction claims will become scientifically substantiated.

This study examined consumers' willingness to buy functional foods. Data were collected from an Internet survey in Germany (n = 502) and China (n = 443). The results showed that consumers in China were much more willing to buy functional foods, compared with their German counterparts. A substantial segment of the German consumers indicated lower willingness to buy functional foods, compared with the same foods without additional health benefits. The findings further showed that in both countries, the participants with higher health motivation and more trust in the food industry reported higher willingness to buy functional foods than the participants with lower health motivation and less trust in the industry. Food neophobia had a negative impact on acceptance of functional foods in the Chinese sample. No such association was observed for the German sample. The results suggest that cultural factors play a significant role in the acceptance of functional foods; therefore, caution should be exercised in generalizing research findings from Western countries to others.

Probiotics are live microbial food supplements that benefit the host animal by improving intestinal microbial balance. When they are fed in yogurts, they can fall into the category of functional foods. Functional foods include these probiotics, prebiotics, and, to a certain extent, dietary fiber. Prebiotics are nondigestible food ingredients or supplements that alter the intestinal flora and stimulate the growth of healthy bacteria. Dietary fibers are part of plant foods that are nonstarch polysaccharides and are poorly digested or not digested by human enzymes. The physiologic process in which probiotics and functional foods affect the intestinal flora is through the balance of the intestinal microecology. This review looks at the four major components of intestinal microecology and describes the probiotics in use today and their clinical relevance. Although probiotics hold great promise and appear to be useful in some settings, more clinical study is needed to firmly establish the relevance of probiotic therapy.

This paper investigated the role of grocery store prices in structuring food access for low-income households in Portland, Oregon. We conducted a detailed healthful foods market basket survey and developed an index of store cost based on the USDA Thrifty Food Plan. Using this index, we estimated the difference in street-network distance between the nearest low-cost grocery store and the nearest grocery store irrespective of cost. Spatial regression of this metric in relation to income, poverty, and gentrification at the census tract scale lead to a new theory regarding food access in the urban landscape. Food deserts are sparse in Portland, but food mirages are abundant, particularly in gentrifying areas where poverty remains high. In a food mirage, grocery stores are plentiful but prices are beyond the means of low-income households, making them functionally equivalent to food deserts in that a long journey to obtain affordable, nutritious food is required in either case. Results suggested that evaluation of food environments should, at a minimum, consider both proximity and price in assessing healthy food access for low-income households.

The popularity of functional foods continues to increase as consumers desire flavorful foods that will fulfil their health needs. Among these foods, probiotics may exert positive effects on the composition of gut microbiota and overall health. However, in order to be beneficial, the bacterial cultures have to remain live and active at the time of consumption. The aim of this study was to develop new probiotic food products, such as seasoned cheeses, salami, chocolate and ice-cream with a final probiotic concentration of approximately 10⁹CFU/daily dose of Lactobacillus rhamnosus IMC 501® and Lactobacillus paracasei IMC 502® mixed 1:1 (SYNBIO®). The survival and viability of probiotics were determined during the foods shelf-life. The values of viable probiotic bacteria of all dairy and non-dairy foods were between 10⁷ and 10⁹CFU/g of food at the end of the shelf-life and for some of them the values were maintained even after the expiry date. Based on the results of the current study, all the dairy ("Caciotta" cheese, "Pecorino" cheese, "Büscion" Swiss cheese and "Fiordilatte" ice-cream) and non-dairy ("Ciauscolo" salami, Larded salami, Swiss small salami, milk chocolate, dark chocolate, organic jam and chocolate mousse) food products studied would be excellent vehicles to deliver the probiotic health effects because of the high viability of probiotics during the shelf-life of foods and in some cases even after their expiry date.

This paper reviews the potential of prebiotic-containing foods in the prevention or postponement of certain diet-related diseases, such as cardiovascular diseases with hypercholesterolemia, osteoporosis, diabetes, gastrointestinal infections and gut inflammation. Also the data on prebiotics as food ingredients and their impact on food product quality are presented. Prebiotics are short chain carbohydrates that are resistant to the digestion process in the upper part of the digestive system, are not absorbed in any segment of the gastrointestinal system, and finally are selectively fermented by specific genera of colonic bacteria. The mechanisms of the beneficial impacts of prebiotics on human health are very difficult to specify directly, because their health-promoting functions are related to fermentation by intestinal microflora. The impact of prebiotics on diet-related diseases in many ways also depends on the products of their fermentation. Prebiotics as functional food ingredients also have an impact on the quality of food products, due to their textural and gelling properties. Prebiotics as food additives can be very valuable in the creation of functional food aimed at preventing or postponing many diet-related diseases. They additionally have beneficial technological properties which improve the quality of food products.

In addition to providing specific sensory properties (e.g., flavor or textures), there is a need to produce foods that also provide functionality within the gastrointestinal (GI) tract, over and above simple nutrition. As such, there is a need to understand the physical and chemical processes occurring in the mouth, stomach, small intestine, and large intestine, in addition to the food structure-physiology interactions. In vivo techniques and in vitro models have allowed us to study and simulate these processes, which aids us in the design of food microstructures that can provide functionality within the human body. Furthermore, it is important to be aware of the health or nutritional needs of different groups of consumers when designing food structures, to provide targeted functionality. Examples of three groups of consumers (elderly, obese, and athletes) are given to demonstrate their differing nutritional requirements and the formulation engineering approaches that can be utilized to improve the health of these individuals. Eating is a pleasurable process, but foods of the future will be required to provide much more in terms of functionality for health and nutrition.

Proteins in foods serve dual roles as nutrients and structural building blocks. The concept of protein functionality has historically been restricted to nonnutritive functions--such as creating emulsions, foams, and gels--but this places sole emphasis on food quality considerations and potentially overlooks modifications that may also alter nutritional quality or allergenicity. A new model is proposed that addresses the function of proteins in foods based on the length scale(s) responsible for the function. Properties such as flavor binding, color, allergenicity, and digestibility are explained based on the structure of individual molecules; placing this functionality at the nano/molecular scale. At the next higher scale, applications in foods involving gelation, emulsification, and foam formation are based on how proteins form secondary structures that are seen at the nano and microlength scales, collectively called the mesoscale. The macroscale structure represents the arrangements of molecules and mesoscale structures in a food. Macroscale properties determine overall product appearance, stability, and texture. The historical approach of comparing among proteins based on forming and stabilizing specific mesoscale structures remains valid but emphasis should be on a common means for structure formation to allow for comparisons across investigations. For applications in food products, protein functionality should start with identification of functional needs across scales. Those needs are then evaluated relative to how processing and other ingredients could alter desired molecular scale properties, or proper formation of mesoscale structures. This allows for a comprehensive approach to achieving the desired function of proteins in foods.
Before answering the question of when dietary fiber can be considered a functional food we must first decide what can be called a dietary fiber. The generally accepted definition of dietary fiber is that of Trowell that dietary fiber consists of the remnants of edible plant cells polysaccharides, lignin, and associated substances resistant to (hydrolysis) digestion by the alimentary enzymes of humans. In Japan the food tables list the dietary fiber content of animal as well as plant tissues, while many countries accept saccharides of less than DP-10 as dietary fiber (inulin, oligofructose, Fibersol-2, polydextrose, fructooligosaccharides, galactooligosaccharides etc.). These shorter chain oligosaccharides do not precipitate as dietary fiber in the standard Association of Official Analytical Chemists (AOAC) method, which is accepted by the US Food & Drug Administration, the US Department of Agriculture and the Food & Agriculture Organization of the World Health Organization for nutrition labeling purposes. In the United Kingdom the term dietary fiber has been replaced in nutrition labeling by nonstarch polysaccharides. Therefore the American Association of Cereal Chemists (AACC) commissioned an ad hoc committee of scientists to evaluate continuing validity of the currently used definition, and if appropriate, to modify and update that definition. Obtaining scientific input from the community of analysts, health professionals, and dietary fiber researchers was considered a high priority. To this end three meetings were held in the space of six months to assure input from all persons knowledgeable in the field with the answer expected sometime before 2000. Dietary fiber can be considered a functional food when it imparts a special function to that food aside from the normal expected function and similarly when the dietary fiber is used as an additive to foods. For example, dietary fiber contributes to colonic health, bifidobacterial or lactobacillus stimulation in the

The present modelling study aimed to evaluate if and by how much functional foods containing phytosterols/-stanols add to the benefits of statins in the prevention of cardiovascular disease in terms of cost-effectiveness. Long-term health effects, measured as quality-adjusted life-years gained, and costs for scenarios with additional phytosterol/-stanol use were compared to scenarios without extra use. Phytosterols/-stanols were given only to persons who were eligible for use according to their 10-year absolute risk of fatal cardiovascular disease (SCORE-risk). Intake levels and discontinuation rates as observed in daily practice were included in the model. Two situations were compared: 1) A real-life situation in which persons at high SCORE-risk were identified through clinical case-finding and, 2) A theoretical maximum situation where universal screening was implemented resulting in known SCORE-risks for the whole Dutch population aged 35-75 years (8.4 million people). Sensitivity analyses were performed for variations in the cholesterol-lowering effect and intake level of phytosterols/-stanols, indirect health care costs, time horizon and discount rates. At the model's start year, a total of 1.0 (real-life situation) to 3.3 (maximum situation) million persons qualified for phytosterol/-stanol use based on their SCORE-risk (both statin users and statin non-users). Over the model's time horizon, this resulted in a gain of 2700 to 16,300 quality-adjusted life-years, and yielded cost-effectiveness ratios that ranged between €92,000 and €203,000 per quality-adjusted life-year. This simulation study showed that the cost-effectiveness of phytosterols/-stanols as monotherapy and as add-on to statins is above thresholds for cost-effectiveness, generally ranging between €20,000 and €50,000, and is thus a non-cost-effective strategy to reduce cardiovascular disease.
Background The functional food industry has experienced innovative and economic expansion, yet research into consumer perceptions of functional foods and their associated health claims is limited. Among consumers, older adults could benefit from functional foods due to age-related issues pertaining to food and health. The purpose of this research was to identify the need for information related to functional foods among older adults (≥60 years old) and to assess awareness and perceptions of health claims on functional food packages. Methods Community-dwelling older adults (n = 200) completed a researcher administered questionnaire designed to collect information about functional foods including current consumption, motivating factors for consumption, perceived need for information, sources of information for functional foods and awareness of health claims. Results Prevalence of functional food consumption among participants was 93.0%. Increased awareness and knowledge was the most commonly reported factor that would promote functional food consumption (85.5%) and 63.5% of participants wanted more information about functional foods with preferred sources being newspapers/magazines/books (68.5%) and food labels (66.1%). Participants were predominately (93.5%) aware of health claims on functional foods and those with more education were more likely to report being aware of health claims (p = 0.045). Conclusions Although functional food consumption among older adults in this sample is high, there is a need for further information regarding functional foods. These results inform stakeholders regarding the potential for information to influence functional food acceptance among older adult consumers. PMID:24886306

Flaxseed is emerging as an important functional food ingredient because of its rich contents of α-linolenic acid (ALA, omega-3 fatty acid), lignans, and fiber. Flaxseed oil, fibers and flax lignans have potential health benefits such as in reduction of cardiovascular disease, atherosclerosis, diabetes, cancer, arthritis, osteoporosis, autoimmune and neurological disorders. Flax protein helps in the prevention and treatment of heart disease and in supporting the immune system. As a functional food ingredient, flax or flaxseed oil has been incorporated into baked foods, juices, milk and dairy products, muffins, dry pasta products, macaroni and meat products. The present review focuses on the evidences of the potential health benefits of flaxseed through human and animals' recent studies and commercial use in various food products.

Functional foods are the focus of many studies worldwide. This is justified by the effects they have on public health and thus interest in elucidation of the mechanisms involved in their actions. The present review aims to broaden the discussions of the functional properties attributed to yacon (Smallanthus sonchifolius), considered a food with multiple functions since it possesses bioactive compounds (antimicrobial, antioxidant, and probiotic substances) that exert beneficial effects on the body. Although some studies have already demonstrated several of these functions, clinical evidence is scarce, making it necessary that more studies are conducted in this area. Still, since the availability of this food in the market is relatively new, its popularity depends on publications aimed at consumer education and development of new products by the food industry.

A probiotic is a viable microbial dietary supplement that beneficially affects the host through its effects in the intestinal tract. Probiotics are widely used to prepare fermented dairy products such as yogurt or freeze-dried cultures. In the future, they may also be found in fermented vegetables and meats. Several health-related effects associated with the intake of probiotics, including alleviation of lactose intolerance and immune enhancement, have been reported in human studies. Some evidence suggests a role for probiotics in reducing the risk of rotavirus-induced diarrhea and colon cancer. Prebiotics are nondigestible food ingredients that benefit the host by selectively stimulating the growth or activity of one or a limited number of bacteria in the colon. Work with prebiotics has been limited, and only studies involving the inulin-type fructans have generated sufficient data for thorough evaluation regarding their possible use as functional food ingredients. At present, claims about reduction of disease risk are only tentative and further research is needed. Among the claims are constipation relief, suppression of diarrhea, and reduction of the risks of osteoporosis, atherosclerotic cardiovascular disease associated with dyslipidemia and insulin resistance, obesity, and possibly type 2 diabetes. The combination of probiotics and prebiotics in a synbiotic has not been studied. This combination might improve the survival of the bacteria crossing the upper part of the gastrointestinal tract, thereby enhancing their effects in the large bowel. In addition, their effects might be additive or even synergistic.
This paper considers how consumers make sense of food labeling, drawing on a qualitative, empirical study in England. I look in detail at two examples of labeling: 1) food certified as produced by organic methods and 2) functional food claimed to be beneficial for human health, especially probiotic and cholesterol-lowering products. I use the concept of "boundary objects" to demonstrate how such labels are intended to work between the worlds of food producers and food consumers and to show how information is not merely transferred as a "knowledge fix" to consumer ignorance. Rather, consumers drew on a binary of "raw" and "processed" food and familiarity with marketing in today's consumer culture to make sense of such labeling.

Background: Food insecurity is associated with nutrient inadequacy and a variety of unfavorable health outcomes. However, little is known about whether food security is associated with lower cognitive function in the elderly. Objective: We investigated the prevalence of food insecurity in a representative sample of 1358 Puerto Ricans aged 45–75 y living in Massachusetts in relation to cognitive function performances. Design: Food security was assessed with the US Household Food Security Scale. Cognitive function was measured to capture general cognition with a battery of 7 tests: Mini-Mental State Examination (MMSE), word list learning (verbal memory), digit span (attention), clock drawing and figure copying (visual-spatial ability), and Stroop and verbal fluency tests (fluency executive functioning). Results: The overall prevalence of food insecurity during the past 12 mo was 12.1%; 6.1% of the subjects reported very low food security. Food insecurity was inversely associated with global cognitive performance, as assessed by the MMSE score. The adjusted difference in the MMSE score was −0.90 (95% CI: −1.6, −0.19; P for trend = 0.003) for a comparison of participants with very low food security with those who were food secure, after adjustment for age, smoking, education, poverty status, income, acculturation, plasma homocysteine, alcohol, diabetes, and hypertension. Food insecurity was significantly associated with lower scores for word-list learning, percentage retention, letter fluency, and digit span backward tests. Conclusions: Very low food security was prevalent among the study subjects and was associated with lower cognitive performance. Further studies, both observational and experimental, are warranted to clarify the direction of causality in this association. PMID:19225117

There has been surprisingly little research to date on the supply-side role of food manufacturers on equilibrium health outcomes for consumers. In this letter we consider an oligopoly model in which food processors choose the health composition of manufactured food. We show that price competition between food processors leads to unhealthy food composition in the market equilibrium, even under circumstances in which consumers know food composition is unhealthy. Taxes on manufactured food decrease the healthiness of manufactured foods whenever improved consumer health increases the price elasticity of food demand. Copyright © 2016 John Wiley & Sons, Ltd.

The functional foods sector represents a significant and growing portion of the food industry, yet formulation of these products often involves the use of ingredients that elicit less than desirable oral sensations, including bitterness. Promising new functional ingredients, including polyphenolics, may be more widely and readily employed in the creation of novel functional foods if their aversive bitter taste can be significantly reduced. A number of approaches are used by the industry to improve the taste properties and thus the acceptance of conventional foods that elicit excessive bitterness. This article reviews the most commonly employed techniques, including the use of bitter-modifying additives, which may prove useful for successfully introducing new functional ingredients into this rapidly growing sector.

Background: During the last decades, there have been great advancements in the field of preventive medicine. Research has demonstrated that nutrition plays a crucial role in the prevention of chronic diseases. The concept of functional food was first introduced in Japan during the 1980s. It proposes to consider food not only vital to survive, but also a mean for mental and physical well-being, contributing to the prevention and reduction of risk factors for diseases. However, there is evidence that the concept was believed by ancient physicians as well. One of the traditional systems of medicines is traditional Persian medicine (TPM). Rhazes said; “as long as a disease could be treated with food, medicine should be avoided” Methods: We carried out a review of Avicenna’s Canon of medicine and Rhazes books for the definition of food and drug and similar concepts of functional food. We listed the identified concepts along with their examples. Results: The classification of food and their therapeutic use were explained in Canon of medicine. Rhazes has a book called ‘Manafe al-Aghziyeh’, in which he writes about the medicinal benefits of different nutrition. Five concepts (food, drug, medicinal food, nutritional medicine and antidote or poison) were noted in these books. Conclusion: There are many recommendations on food for the prevention and treatment of diseases in TPM books, which can be the basis for novel research studies. PMID:27516666

Evidence is rapidly accumulating as to the beneficial effects of foods. However, it is not always clear whether the information is based on data evaluated impartially in a scientific fashion. Human research into whether foods modulate immune functions in either intervention studies or randomized controlled trials can be classified into three categories according to the physical state of subjects enrolled for investigation: (i) studies examining the effect of foods in healthy individuals; (ii) studies analyzing the effect of foods on patients with hypersensitivity; and (iii) studies checking the effect of foods on immunocompromized subjects, including patients who had undergone surgical resection of cancer and newborns. The systematization of reported studies has made it reasonable to conclude that foods are able to modulate immune functions manifesting as either innate immunity (phagocytic activity, NK cell activity) or acquired immunity (T cell response, antibody production). Moreover, improvement of immune functions by foods can normalize the physical state of allergic patients or cancer patients, and may reduce the risk of diseases in healthy individuals. Therefore, it is valuable to assess the immune-modulating abilities of foods by measuring at least one parameter of either innate or acquired immunity. PMID:15841257

Food products containing probiotics and prebiotics are an important development in Health foods, which enhance health promoting microbial flora in the intestine. Probiotic refers to viable microorganism that promotes or support a beneficial balance of the autochthonous microbial population of the gastrointestinal tract. A number of genera of bacteria (and yeast) are used as probiotics, including Lactobacillus, Leuconostoc, Pediococcus, Bifidobacterium, Saccharomyces, and Enterococcus, but the main species believed to have probiotic characteristics are Lactobacillus acidophilus, Bifidobacterium spp., and L. casei. Probiotics can reduce diarrheal incidence, lactose intolerance, lower serum cholesterol, stimulate the immune system, control infections, act as antibiotics, suppress tumors, and protect against colon or bladder cancer by maintaining a healthy intestinal microflora balance. Lactic acid bacteria produce biopreservatives such as lactic acid, hydrogen peroxide, and bacteriocins that are used to retard both spoilage and the growth of pathogenic bacteria. Food, particularly dairy products are considered as an ideal vehicle for delivering probiotic bacteria to the human gastrointestinal tract. Cereals being rich source of prebiotics such as β-glucan and arabinoxylan, galacto-, and fructooligosaccharides are considered for development of probiotic foods. Good manufacturing practices must be applied in the manufacture of probiotic foods with quality assurance, and shelf-life conditions established.

Food-grade phosphates are used in the production of foods to function as buffers, sequestrants, acidulants, bases, flavors, cryoprotectants, gel accelerants, dispersants, nutrients, precipitants, and as free-flow (anticaking) or ion-exchange agents. The actions of phosphates affect the chemical leavening of cakes, cookies, pancakes, muffins, and doughnuts; the even melt of processed cheese; the structure of a frankfurter; the bind and hydration of delicatessen meats; the fluidity of evaporated milk; the distinctive flavor of cola beverages; the free flow of spice blends; the mineral content of isotonic beverages; and the light color of par-fried potato strips. In the United States, food-grade phosphates are generally recognized as safe, but use levels have been defined for some foods by the Code of Federal Regulations, specifically Titles 9 and 21 for foods regulated by the U.S. Department of Agriculture (USDA) and the U.S. Food and Drug Administration (FDA), respectively. Standards for food purity are defined nationally and internationally in sources such as the Food Chemicals Codex and the Joint Food and Agriculture Organization and World Health Organization (FAO/WHO) Expert Committee on Food Additives.

Research has proved a relationship between functional components of food, health and well-being. Thus, functional components of food can be effectively applied in the treatment and prevention of diseases. They act simultaneously at different or identical target sites with the potential to impart physiological benefits and promotion of wellbeing including reducing the risk of cancer, cardiovascular disease, osteoporosis, inflammation, type II diabetes, and other chronic degenerative diseases, lowering of blood cholesterol, neutralization of reactive oxygen species and charged radicals, anticarcinogenic effect, low-glycaemic response, etc. Previously, it was thought that functional ingredients such as non-starchy carbohydrates including soluble and insoluble dietary fibres, fucoidan; antioxidants including polyphenols, carotenoids, tocopherols, tocotrienols, phytosterols, isoflavones, organosulphur compounds; plant sterols and soy phytoestrogens occur only in plant foods (whole grains, fruits, and vegetables) as phytochemicals. However, probiotics, prebiotics, conjugated linolenic acid, long-chain omega-3, -6 and -9-polyunsaturated fatty acids, and bioactive peptides have proved that functional components are equally available in animal products such as milk, fermented milk products and cold-water fish. The way a food is processed affects its functional components. Many processing techniques have been found to lower the concentration of functional components in food. Conversely, other techniques were found to increase them. Hence, in a time when the role of a healthy diet in preventing non-communicable diseases is well accepted, the borderline between food and medicine is becoming very thin.

Although botanicals have played a role in the marketing of health products for ages, there is an increased interest today due to their perceived health benefits. Not only do consumers increasingly take charge of their health, but the scientific information and understanding of the beneficial health effects of bioactive substances in food, functional foods and food supplements have improved. Increasing use of these products has also led to concerns about their actual safety. Recorded cases of intoxications have triggered such concerns. The safety assessment of these substances is complicated by, amongst others, the variability of composition. Furthermore, consumption of such functional products is expected to produce physiological effects, which may lead to low margins of safety as the margin between exposure of such products and the safe level of intake are likely to be small. The safety assessment of botanicals and botanical preparations in food and food supplement should at least involve: the characterisation and quality of the material, its quality control; the intended use and consequent exposure; history of use and exposure; product comparison(s); toxicological information gathering; Risk characterisation/safety assessment. As a guidance tool, a decision tree approach is proposed to assist in determining the extent of data requirements based on the nature of the such product. This guidance tool in safety assessment was developed by an expert group of the International Life Sciences Institute (ILSI), European Branch, and is currently in press. In this paper a summarised version of this tool is presented.

Affluent diets have negative effects on the health of the population and the environment. Moreover, the ability of industrialised agricultural ecosystems to continue to supply these diets is threatened by the anticipated consequences of climate change. By challenging the ongoing supply the diets of affluent countries, climate change provides a population and environmental health opportunity. This paper contrasts two strategies for dealing with climate change-related food insecurity. Functional foods are being positioned as one response because they are considered a hyper-efficient mechanism for supplying essential micronutrients. An alternative response is civic and urban agriculture. Rather than emphasising increased economic or nutritional efficiencies, civic agriculture presents a holistic approach to food security that is more directly connected to the economic, environmental and social factors that affect diet and health.

As genetically modified (GM) foods are starting to intrude in our diet concerns have been expressed regarding GM food safety. These concerns as well as the limitations of the procedures followed in the evaluation of their safety are presented. Animal toxicity studies with certain GM foods have shown that they may toxically affect several organs and systems. The review of these studies should not be conducted separately for each GM food, but according to the effects exerted on certain organs it may help us create a better picture of the possible health effects on human beings. The results of most studies with GM foods indicate that they may cause some common toxic effects such as hepatic, pancreatic, renal, or reproductive effects and may alter the hematological, biochemical, and immunologic parameters. However, many years of research with animals and clinical trials are required for this assessment. The use of recombinant GH or its expression in animals should be re-examined since it has been shown that it increases IGF-1 which may promote cancer.
The number of foods bearing health and nutrition claims is growing in line with consumers' expectations. This market offers attractive prospects of profit for industry and commerce. The question is whether such foods really have health effects, and whether the general population or specific groups really benefit from their use. Specific regulations are needed to define the conditions of validation, communication and follow-up of such claims. The European Community's internal market is currently governed by a fragmented set of regulations and enforcement systems. Member states' national regulations differ in substance and application. For these reasons, the European Commission is seeking to create and adopt a common regulation. The following article considers the main stakes relating to consumers' health expectations, public health, and industrial and commercial interests, together with the origins of the concept of "functional foods". In contrast to the 'product based' approach in other cultures (Japan, North America, etc.), Europe has chosen a 'science based' approach focusing on physiological functions. In particular, Europe funded the FUFOSE program (Functional Food Science in Europe) coordinated by ILSI (International Life Science Institute). The bases of true functional food science are considered--how to identify beneficial interactions between food components and specific body functions, and to understand the underlying mechanisms in order to construct hypotheses for testing on volunteers. A methodology based on biological markers has been developed Europe then funded the PASSCLAIM program (Process for the assessment of scientific support for claims on foods) aimed at identifying relationships between a functional effect (normal or enhanced function) and a health benefit or a reduced risk of disease. Selected aspects of these 10-year programs illustrate the scientific bases for a European regulation of nutrition claims and so-called health claims (improved

New developments in nutrigenetic research and the European regulation 1924/2006 on health claims have spurred interest in developing and marketing functional food designed for personalized nutrition. Personalized nutrition uses genetic information regarding a person's health risk profile. Specifically adapted nutrition recommendations are claimed to help reducing disease risk. An internet survey was conducted in December 2007 using a sample of 452 randomly selected adults in Germany. The survey instrument assesses if consumers would be willing to participate in genetic risk profiling, if they are interested in personalized nutrition advice and if they desire functional food products adapted to their individual nutrigenetic profile. In addition, we estimate the acceptance of functional food products designed to reduce the risk of cardio-vascular diseases. Consumers have a positive attitude towards the testing of their genetic profile to be used in nutrient advice. About 45 % of the sample would agree to such a test and like to obtain a personalized advice on nutrition. Similarly, more than 40 % of the sample showed a positive willingness to buy the proposed functional food products. Given these results, the concept of personalized nutrition seems promising. However, several challenges remain regarding targeted nutrition advice and food marketing.

The viewpoints of "medicine food homology" (MFH) conform to today's food requirements of returning to a natural and green healthy life. This paper aims to introduce the concept of MFH and its origin and evolution, and analyze the relationship between food and Chinese medicine. In this review, more than 80 MFH materials approved by China's Ministry of Health are listed and their effective ingredients are summarized in detail. Their treatment mechanism in TCM and western medicine are summarized too. Moreover, some new MFH resources that have been gradually developed are also introduced. MFH materials are a treasure house of functional factors for current functional foods. Innovative ideas for the development of MFH resources in current functional foods are prospected and discussed, such as taking advantage of Chinese diet theory, building a database for MFH varieties and developing new methods and technologies. At present, modern research for the development of MFH functional foods is still in its primary stage, there is still much work required in the popularization of the MFH concept and the development of new products. Knowledge and technological innovations in this area should be accelerated in the future to promote the modernization of MFH.

Food insecurity is estimated to affect about 10% of the United States population. Rural areas experience even higher rates and intensity of food security problems related to poverty, food access, and higher food costs. Reports of the relationship between household food security and health status, however, are limited. This report examines the relationship between household food security and measures of functional health status in a rural Appalachian sample. A comprehensive health status survey was completed by 1,006 individuals seen either in a clinical (n = 605) or nonclinical (n = 401) community setting. The survey included the USDA Food Security Core Module, the SF-36, and demographic and health care access questions. Household food insecurity was reported by 23% of respondents. Food insecure respondents reported significantly poorerfunctional status on all SF-36 scales compared tofood secure respondents (all p < 0.05). After adjusting for demographic and access variables in a multiple regression analysis, food insecurity remained a significant independent predictor of responses for each SF-36 scale. Generalizability of results are limited by the convenience sampling methods and geographic region in which the study was conducted. In this preliminary study, even minimal levels of food insecurity are related to self-reported levels of health status as measured by the SF-36 spectrum. Health professionals must be able to identify individuals at risk for food insufficiency; policy makers must develop more effective programs for alleviating the basic causes of food insecurity.
A food can be regarded as functional if it is satisfactorily demonstrated to affect beneficially one or more target functions in the body, beyond adequate nutritional effects, in a way which is relevant to either the state of wellbeing and health or the reduction of the risk of a disease. A food can be made functional by increasing the concentration, adding or improving the bioavailability of a particular component. Functional food science will serve to establish claims based either on enhanced function or disease risk reduction. Inulin and oligofructose are functional food ingredients present in miscellaneous edible plants. They are non-digestible oligosaccharides classified as dietary fibres. The target for their functional effects is the colonic microflora that ferment them and for which they serve as selective "fertilizers"; the gastrointestinal physiology; the immune functions; the bioavailability of minerals; the metabolism of lipids; and colonic carcinogenesis. The scientific data available on the nutritional effects of inulin and oligofructose provide strong evidence for a prebiotic effect (i.e., selective stimulation of growth of bifidobacteria in colonic microbiota), improvement of bowel habit (both stool frequency and stool weight) and improved calcium bioavailability.

Increasing consumer knowledge of the link between diet and health has raised the awareness and demand for functional food ingredients. Meat and its derivatives may be considered functional foods to the extent that they contain numerous compounds thought to be functional. This review will attempt to outline the excellent nutritional and dietetic properties of rabbit meat and offer an overview of the studies performed on the strategies adopted to improve the functional value of rabbit meat. Dietary manipulation has been seen to be very effective in increasing the levels of essential FA, EPA, DHA, CLA, branched chain FA, vitamin E, and selenium in rabbit meat. Dietary fortification with vitamin E or natural products such as oregano essential oil, chia seed oil, and Spirulina platensis microalga seem promising in improving the oxidative stability of rabbit meat while also adding functional ingredients.

Purpose: The association between food insecurity and health-related quality of life (QOL) of racial/ethnic minority patients with cancer has not been examined. The purpose of this study is to determine the relationship between food insecurity and health-related QOL reported by racial/ethnic minority patients with cancer. Methods: A consecutive sample of 1,390 underserved ethnic minority patients receiving cancer care in 10 cancer clinics and hospitals in New York City participated in this study. Health-related QOL was measured by the Functional Assessment of Cancer Therapy-General (FACT-G) and food security was assessed by the US Department of Agriculture Core Food Security Module. Results: Of the 1,390 patients, 581 (41.8%) were classified as food secure, 571 (41.1%) with low food security, and 238 (17.1%) with very low food security. Health-related QOL decreased with each lower food security level. Patient self-reported physical, functional, social, and emotional well-being subscale scores decrease significantly with increasing food insecurity. After controlling for demographic and medical-related factors, the decreases in QOL, physical, functional, social and emotional well-being scores with increasing food insecurity remained significant. Conclusion: Food insecurity was associated with lower QOL in this sample of underserved racial/ethnic minority patients with cancer. Underserved ethnic minority patients diagnosed with cancer are a vulnerable patient population, at significant risk for inadequate food access and the related lower QOL. PMID:26286100
This paper offers a concise review of technical and operational concepts underpinning commercialization of minimally processed functional foods (FFs), foods with fresh-like qualities commanding premium prices. The growing number of permitted nutritional content/health claims, many of which relate to well-being, coupled with emerging extraction and food processing technologies offers new exciting opportunities for small and medium size enterprises (SMEs) specializing in fresh produce to play an active role in the health market. Supporting SMEs, governments could benefit from savings in healthcare costs and value creation in the economy. Consumers could benefit from novel FF formats such as refrigerated RTE (ready-to-eat) meals, a variety of fresh-like meat-, fish-, and egg-based products, fresh-cut fruits and vegetables, cereal-based fermented foods and beverages. To preserve these valuable commodities, mild biological (enzymatic treatment, fermentation and, bio-preservation) and engineering solutions are needed. The latter include nonthermal techniques such as high-pressure treatment, cook-chill, sous-vide, mirco-encapsulation, vacuum impregnation and others. "De-constructive" culinary techniques such as 3D food printing and molecular gastronomy as well as developments in nutrigenomics and digital technologies facilitate novel product formats, personalization and access to niche markets. In the operational sense, moving from nourishment to health improvement demands a shift from defensive market-oriented to offensive market-developing strategies including collaborative networks with research organizations.

There has been growing policy interest in social justice issues related to both health and food. We sought to understand the state of knowledge on relationships between health equity--i.e. health inequalities that are socially produced--and food systems, where the concepts of 'food security' and 'food sovereignty' are prominent. We undertook exploratory scoping and mapping stages of a 'meta-narrative synthesis' on pathways from global food systems to health equity outcomes. The review was oriented by a conceptual framework delineating eight pathways to health (in)equity through the food system: 1--Multi-Scalar Environmental, Social Context; 2--Occupational Exposures; 3--Environmental Change; 4--Traditional Livelihoods, Cultural Continuity; 5--Intake of Contaminants; 6--Nutrition; 7--Social Determinants of Health and 8--Political, Economic and Regulatory context. The terms 'food security' and 'food sovereignty' were, respectively, paired with a series of health equity-related terms. Combinations of health equity and food security (1414 citations) greatly outnumbered pairings with food sovereignty (18 citations). Prominent crosscutting themes that were observed included climate change, biotechnology, gender, racialization, indigeneity, poverty, citizenship and HIV as well as institutional barriers to reducing health inequities in the food system. The literature indicates that food sovereignty-based approaches to health in specific contexts, such as advancing healthy school food systems, promoting soil fertility, gender equity and nutrition, and addressing structural racism, can complement the longer-term socio-political restructuring processes that health equity requires. Our conceptual model offers a useful starting point for identifying interventions with strong potential to promote health equity. A research agenda to explore project-based interventions in the food system along these pathways can support the identification of ways to strengthen both food

The market for organic food products is growing rapidly worldwide. Such foods meet certified organic standards for production, handling, processing, and marketing. Most notably, the use of synthetic fertilizers, pesticides, and genetic modification is not allowed. One major reason for the increased demand is the perception that organic food is more environmentally friendly and healthier than conventionally produced food. This review provides an update on market data and consumer preferences for organic food and summarizes the scientific evidence for compositional differences and health benefits of organic compared with conventionally produced food. Studies indicate some differences in favor of organic food, including indications of beneficial health effects. Organic foods convey lower pesticide residue exposure than do conventionally produced foods, but the impact of this on human health is not clear. Comparisons are complicated by organic food consumption being strongly correlated with several indicators of a healthy lifestyle and by conventional agriculture "best practices" often being quite close to those of organic.
Increasing knowledge on the link between diet and human health has generated a lot of interest in the development of functional foods. However, several challenges, including discovering of beneficial compounds, establishing optimal intake levels, and developing adequate food delivering matrix and product formulations, need to be addressed. A number of new processes and materials derived from nanotechnology have the potential to provide new solutions in many of these fronts. Nanotechnology is concerned with the manipulation of materials at the atomic and molecular scales to create structures that are less than 100 nm in size in one dimension. By carefully choosing the molecular components, it seems possible to design particles with different surface properties. Several food-based nanodelivery vehicles, such as protein-polysaccharide coacervates, multiple emulsions, liposomes and cochleates have been developed on a laboratory scale, but there have been very limited applications in real food systems. There are also public concerns about potential negative effects of nanotechnology-based delivery systems on human health. This paper provides an overview of the new opportunities and challenges for nanotechnology-based systems in future functional food development.

Food advertising increasingly portrays food as a type of medicine. A content analysis of magazine food advertisements in 1990 through 2008 shows that this was manifested with time more in the (a) nutrition claims and (b) health claims made in food advertisements, as well as the (c) food groups and (d) media genres to which nutrition and health claims in food advertising pertained. This so-called "medicalisation" of food advertising may promote images of the body and mind as malfunctioning unless remedied by the use of--advertised--products.

Poor nutrition, foodborne disease and lack of secure access to good food make an important contribution to the burden of disease and death in the WHO European Region. Better diets, food safety and food security will not only reduce or prevent suffering to individuals and societies but also help cut costs to health care systems and bring social and economic benefits to countries. People's chances for a healthy diet depend less on individual choices than on what food is available and whether it is affordable. Policies to benefit health through good food and nutrition must extend beyond the health sector to include sectors ranging from agriculture and food processing, manufacturing and trade to transport, retailing, catering and advertising. Food and nutrition policies should be coordinated so that public health is given due priority in the making of food policies by non-health sectors. This publication discusses in depth the components of food and nutrition policies and the evidence supporting them. It describes food- and nutrition-related ill health and its costs, shows the need for action and describes the steps for decision-makers to take. This book highlights the urgent need for integrated, multisectoral food and nutrition policies to encourage the sustainable production of food, its safety and the provision of food of high nutritional quality for all.

The influence of local food environments on the risk for obesity is important overall, but may be particularly important for food insecure populations in urban settings. Access to healthful foods is most limited among racial and ethnic minorities and low-income populations; these same populations experience the highest rates of obesity and food insecurity. Few valid and reliable measures have been developed to assess the quality of local food environments. This research addresses this gap by introducing an inventory for measuring self-reported perceptions of food access and then compares the perceptions measure to objective assessments of local food environments. Data are focused on an urban population experiencing disproportionate rates of food insecurity. The four-item perceptions of food access inventory had high internal consistency (Cronbach's alpha = 0.80). Participants' perceptions of access to healthful foods mirrored the reality of their food environment; however, perceptions of access to alcohol and tobacco were less accurate. Findings suggest that people living in low-income, urban, minority, and food insecure communities can validly assess (in)access to healthful foods. Future research is needed to further validate the perceptions of food access measure introduced and, more importantly, to develop strategies for increasing access to healthful foods in food insecure contexts.
The US Food Security Scale (USFSS) measures household and child food insecurity (CFI) separately. Our goal was to determine whether CFI increases risks posed by household food insecurity (HFI) to child health and whether the Food Stamp Program (FSP) modifies these effects.

Bioactive food components or functional foods have recently received significant attention because of their widely touted positive effects on health beyond basic nutrition. However, a question continues to lurk: are these claims for 'super foods' backed by sound science or simply an exaggerated portrayal of very small 'benefits'? Efforts to establish health benefits by scientific means pose a real challenge in regards to defining what those benefits are, as well as how effective the foods are in justifying any health claim. This review discusses the pitfalls associated with the execution, interpretation, extrapolation of the results to humans and the challenges encountered in the dietary research arena from a basic scientist's perspective.
Diabetes is the common, exponentially growing, serious human health problem existing globally. Risk factors like genetic predisposition, lack of balanced diet, inappropriate and lethargic lifestyle, overweight, obesity, stress including emotional and oxidative and lack of probiotics in gut are found to be the causing factors either in isolation or in synergy predisposing Diabetes. High blood sugar is a common symptom in all types of diabetes mellitus and the physiological cause of diabetes is lack of hormone Insulin or resistance in function faced by insulin. Low levels of Insulin causes decreased utilization of glucose by body cells, increased mobilization of fats from fat storage cells and depletion of proteins in the tissues of the body, keeping the body in crisis. The functional foods help achieving optimal physiological metabolism and cellular functions helping the body to come out of these crises. The mechanism of the functional foods is envisaged to act via optimizing vitamins, minerals, essential amino acids, prebiotics and probiotics. This paper reviews role of functional foods of plant origin in the regulation of blood sugar in type 2 diabetes mellitus and also discusses some vital patents in this area. The article aims at creating awareness about key food ingredients in order to prevent most acute effects of diabetes mellitus and to greatly delay the chronic effects as well.

Because, in general, native starches do not have properties that make them ideally suited for applications in food products, most starch is modified by dervatization to improve its functionality before use in processed food formulations, and because food processors would prefer not to have to use the modified food starch label designation required when chemically modified starches are used, there is considerable interest in providing starches with desired functionalities that have not been chemically modified. One investigated approach is property modification via physical treatments, that is, modifications of starches imparted by physical treatments that do not result in any chemical modification of the starch. Physical treatments are divided into thermal and nonthermal treatments. Thermal treatments include those that produce pregelatinized and granular cold-water-swelling starches, heat-moisture treatments, annealing, microwave heating, so-called osmotic pressure treatment, and heating of dry starch. Nonthermal treatments include ultrahigh-pressure treatments, instantaneous controlled pressure drop, use of high-pressure homogenizers, dynamic pulsed pressure, pulsed electric field, and freezing and thawing.

Background: Household food insecurity, a measure of income-related problems of food access, is growing in Canada and is tightly linked to poorer health status. We examined the association between household food insecurity status and annual health care costs. Methods: We obtained data for 67 033 people aged 18–64 years in Ontario who participated in the Canadian Community Health Survey in 2005, 2007/08 or 2009/10 to assess their household food insecurity status in the 12 months before the survey interview. We linked these data with administrative health care data to determine individuals’ direct health care costs during the same 12-month period. Results: Total health care costs and mean costs for inpatient hospital care, emergency department visits, physician services, same-day surgeries, home care services and prescription drugs covered by the Ontario Drug Benefit Program rose systematically with increasing severity of household food insecurity. Compared with total annual health care costs in food-secure households, adjusted annual costs were 16% ($235) higher in households with marginal food insecurity (95% confidence interval [CI] 10%–23% [$141–$334]), 32% ($455) higher in households with moderate food insecurity (95% CI 25%–39% [$361–$553]) and 76% ($1092) higher in households with severe food insecurity (95% CI 65%–88% [$934–$1260]). When costs of prescription drugs covered by the Ontario Drug Benefit Program were included, the adjusted annual costs were 23% higher in households with marginal food insecurity (95% CI 16%–31%), 49% higher in those with moderate food insecurity (95% CI 41%–57%) and 121% higher in those with severe food insecurity (95% CI 107%–136%). Interpretation: Household food insecurity was a robust predictor of health care utilization and costs incurred by working-age adults, independent of other social determinants of health. Policy interventions at the provincial or federal level designed to reduce household food

Food is fundamental to human survival, in more than just one way. First, food is basic for averting hunger and maintaining health for every human being. Secondly, food satisfies our palate and makes us happy and emotionally and socially content. Third, food constitutes a form of cultural expression. The food we eat should be safe, palatable, affordable, and of the quality that can maintain mental, emotional, physiologic and physical health. Even with globalization that has seen food movements to and from different parts of the world, for most populations in Africa, food is still very locale-specific, especially in the rural farming areas where it is produced. Many locally produced foods have both nutritional and intrinsic value. The types of foods produced in Western Africa are very different from those produced in Eastern Africa. The staple foods, vegetables and the drinks that go with these foods are different. The way food is prepared is also very different in the two parts of Africa. Cultural specificity appears to be more pronounced in Western Africa, involving more secondary processing in the home and more spicing. Data linking food to health, as something that is understood by traditional communities is not easily available. This paper will collate information that discusses people's perceptions in both Western and Eastern Africa, and try to draw comparisons between the two. The paper presents a community picture of food, nutrition and health.

Both national Veterinary Services and international standard-setting organisations have now embraced risk assessment as an essential tool for achieving their goals. Veterinarians have key roles in all aspects of the control of food-borne hazards of animal origin, but additional specialist skills are necessary for assessing, managing and communicating risk. Further, the deployment of Veterinary Services must reflect the multi-functional aspects of public and animal health activities. A generic risk management framework provides a systematic process whereby food safety standards and other measures are chosen and implemented on the basis of knowledge of risk and evaluation of other factors relevant to protecting human health and promoting non-discriminatory trade practices. In this context, a number of countries are exploring new administrative and structural arrangements for competent authorities. The traditional focus of veterinary involvement in food safety has been in meat hygiene at the level of the slaughterhouse. While this role continues, the emerging 'risk-based' approach to food control requires increased involvement in other segments of the meat food chain, as well as other areas such as production of milk and fish. This more extensive role requires a wider skill base and establishment of effective networks with a different range of stakeholders.
The papers in the session "Food Culture and Consumer Response," show how important people's values, beliefs, aspirations and social context are to their dietary health. They also reveal several tensions that shape consumer responses to healthy food. This essay discusses the paradoxical nature of eating habits in general, and describes three paradoxes related specifically to the challenges of providing food for health in the 21st century: pleasure/health, technology/nature, innovation/nostalgia.
It has long been suspected that the relative abundance of specific nutrients can affect cognitive processes and emotions. Newly described influences of dietary factors on neuronal function and synaptic plasticity have revealed some of the vital mechanisms that are responsible for the action of diet on brain health and mental function. Several gut hormones that can enter the brain, or that are produced in the brain itself, influence cognitive ability. In addition, well-established regulators of synaptic plasticity, such as brain-derived neurotrophic factor, can function as metabolic modulators, responding to peripheral signals such as food intake. Understanding the molecular basis of the effects of food on cognition will help us to determine how best to manipulate diet in order to increase the resistance of neurons to insults and promote mental fitness.

Grains are global dietary staples that when consumed in whole grain form, offer considerable health benefits compared with milled grain foods, including reduced body weight gain and reduced cardiovascular and diabetes risks. Dietary patterns, functional foods, and other lifestyle factors play a fundamental role in the development and management of epidemic lifestyle diseases that share risks of developing adverse metabolic outcomes, including hyperglycaemia, hypertension, dyslipidaemia, oxidative stress, and inflammation. Whole grains provide energy, nutrients, fibres, and bioactive compounds that may synergistically contribute to their protective effects. Despite their benefits, the intake of grains appears to be lower than recommended in many countries. Of emerging interest is the application of germination processes, which may significantly enhance the nutritional and bioactive content of grains, as well as improve palatability. Enhancing grain foods in a natural way using germination techniques may therefore offer a practical, natural, dietary intervention to increase the health benefits and acceptability of whole grains, with potentially widespread effects across populations in attenuating adverse lifestyle disease outcomes. Continuing to build on the growing body of in-vitro studies requires substantiation with extended in-vivo trials so that we may further develop our understanding of the potential of germinated grains as a functional food.

Two patients were diagnosed as having hyperthyroidism, and both had taken the same health food. We compared three kinds of histological methods to detect thyroid gland in this health food. The first method used cytology; the second applied the cell-block method; and the last is a modification of the cell particle (CPCB) method proposed by Ushijima. It is the third method that achieved superior results, and this enabled the morphological detection of thyroid gland. Certain kinds of health foods contain dried thyroid as a "slimming supplement", and intake of these products may damage health. Histological techniques are effective for detecting the existence of dried thyroid gland. A health food is very different from clinical specimen; therefore, we have to devise appropriate skills for examining it. Such examinations will be important in the future, because it is expected that the risks of damaging health by consuming certain kinds of health food will increase.

In this article, we critically reflect on the responsibilities that the food industry has for public health. Although food companies are often significant contributors to public health problems (e.g., obesity, type 2 diabetes), the mere possibility of corporate responsibility for public health seems to be excluded in the academic public health discourse. We argue that the behavior of several food companies reflects a split corporate personality, as they contribute to public health problems and simultaneously engage in activities to prevent them. By understanding responsibility for population health as a shared responsibility, we reassess the moral role of the food industry from a forward-looking perspective on responsibility and ask what food companies can and should do to promote health.

Millions of Americans suffer from diseases and conditions that require careful control of their diet as part of treatment. The current solution is to have each person customize their own food choices. Food production automation can enable consumer specific data to be easily integrated into the food as it is being prepared. This would improve the quality and utility of the food without a cognitive burden on the consumer. 3D Printing is an ideal family of technologies for enabling such mass customization of food. Current efforts in 3D printing food are focused on improving the artistic quality of food in the short term and consumer health in the long term.

Adulteration in food has been a concern since the beginning of civilization, as it not only decreases the quality of food products but also results in a number of ill effects on health. Authentic testing of food and adulterant detection of various food products is required for value assessment and to assure consumer protection against fraudulent activities. Through this review we intend to compile different types of adulterations made in different food items, the health risks imposed by these adulterants and detection methods available for them. Concerns about food safety and regulation have ensured the development of various techniques like physical, biochemical/immunological and molecular techniques, for adulterant detection in food. Molecular methods are more preferable when it comes to detection of biological adulterants in food, although physical and biochemical techniques are preferable for detection of other adulterants in food.

It is increasingly recognized that most chronic diseases of concern today are multifactorial in origin. To combat such diseases and adverse health conditions, a treatment approach where medicines and nutrition complement each other may prove to be the most successful. Within nutrition, apart from (disease-related) dietetic regimes, an increasing number of functional foods and dietary supplements, each with their own health claim, are marketed. These food items are considered to be positioned between traditional foods and medicines at the so-called 'Pharma-Nutrition Interface'. This paper encompasses aspects related to the regulatory framework and health claims of functional foods and dietary supplements. The use of functional foods or dietary supplements may offer opportunities to reduce health risk factors and risk of diseases, both as monotherapy and in combination with prescription drugs. Nevertheless, the potential caveats of these products should not be overlooked. These caveats include the increased risk for food-drug interactions due to the elevated amounts of specific functional ingredients in the diet, and the stimulation of self-medication potentially resulting in lower adherence to drug therapy. Health technology assessments should be used more to compare the cost-effectiveness and benefit-risk ratios of drugs, functional foods and dietary supplements, and to evaluate the added value of functional foods or dietary supplements to drug therapy.

In the industrialized world, functional foods have become a part of an everyday diet and are demonstrated to offer potential health benefits beyond the widely accepted nutritional effects. Currently, the most important and frequently used functional food compounds are probiotics and prebiotics, or they are collectively known as 'synbiotics'. Moreover, with an already healthy image, dairy products appear to be an excellent mean for inventing nutritious foods. Such probiotic dairy foods beneficially affect the host by improving survival and implantation of live microbial dietary supplements in the gastrointestinal flora, by selectively stimulating the growth or activating the catabolism of one or a limited number of health-promoting bacteria in the intestinal tract, and by improving the gastrointestinal tract's microbial balance. Hence, the paper reviews the current scenario of probiotics and their prospective potential applications for functional foods for better health and nutrition of the society.

Introduction Food insecurity is negatively associated with health; however, health needs may differ among people participating in food assistance programs. Our objectives were to characterize differences in health among people receiving different types of food assistance and summarize strategies for targeted recruitment and outreach of various food insecure populations. Methods We examined health status, behaviors, and health care access associated with food insecurity and receipt of food assistance among US adults aged 20 years or older using data from participants (N = 16,934) of the National Health and Nutrition Examination Survey from 2005 through 2010. Results Food insecurity affected 19.3% of US adults (95% confidence interval, 17.9%–20.7%). People who were food insecure reported poorer health and less health care access than those who were food secure (P < .001 for all). Among those who were food insecure, 58.0% received no assistance, 20.3% received only Supplemental Nutrition Assistance Program (SNAP) benefits, 9.7% received only food bank assistance, and 12.0% received both SNAP and food bank assistance. We observed an inverse relationship between receipt of food assistance and health and health behaviors among the food insecure. Receipt of both (SNAP and food bank assistance) was associated with the poorest health; receiving no assistance was associated with the best health. For example, functional limitations were twice as prevalent among people receiving both types of food assistance than among those receiving none. Conclusion Receipt of food assistance is an overlooked factor associated with health and has the potential to shape future chronic disease prevention efforts among the food insecure. PMID:27736055

Yacon (Smallanthus sonchifolius) is an Andean tuberous root that is regarded as a functional food given that it contains fructooligosaccharides (FOS), inulin and phenolic compounds. The consumption of FOS and inulin improves the growth of bifidobacteria in the colon, enhances mineral absorption and gastrointestinal metabolism and plays a role in the regulation of serum cholesterol. Furthermore, the literature reports that the consumption of these prebiotics promotes a positive modulation of the immune system, improving resistance to infections and allergic reactions. Certain studies have demonstrated the potential of yacon as an alternative food source for those patients with conditions that require dietary changes. This review intends to describe the potential of yacon as a prebiotic and its cultivation and industrial processing for human consumption.

The involvement of public health professionals in food and agricultural policy provides tremendous opportunities for advancing the public's health. It is particularly challenging, however, for professionals to understand and consider the numerous policy drivers that impact the food system, which range from agricultural commodity policies to local food safety ordinances. Confronted with this complexity in the food system, policy advocates often focus on narrow objectives with disregard for the larger system. This commentary contends that, in order to be most effective, public health professionals need to consider the full range of interdependent policies that affect the system. Food policy councils have proven to be an effective tool, particularly at the local and state level, for developing comprehensive food systems policies that can improve public health. PMID:23144671

Food insecurity is an urgent public health problem in Canada, affecting 4 million Canadians in 2012, including 1.15 million children, and associated with significant health concerns. With little political will to address this significant policy issue, it has been suggested that perhaps it is time for Canada to try a food stamp-style program. Such a program could reduce rates of food insecurity and improve the nutritional health of low-income Canadians. In this article, we explore the history of the US food stamp program; the key impetus of which was to support farmers and agricultural interests, not to look after the needs of people living in poverty. Though the US program has moved away from its roots, its history has had a lasting legacy, cementing an understanding of the problem as one of lack of food, not lack of income. While the contemporary food stamp program, now called Supplemental Nutrition Assistance Program (SNAP), reduces rates of poverty and food insecurity, food insecurity rates in the USA are significantly higher than those in Canada, suggesting a food stamp-style program per se will not eliminate the problem of food insecurity. Moreover, a food stamp-style program is inherently paternalistic and would create harm by reducing the autonomy of participants and generating stigma, which in itself has adverse health effects. Consequently, it is ethically problematic for health promoters to advocate for such a program, even if it could improve diet quality.
Food assistance programs--including the Supplemental Nutrition Assistance Program (SNAP, or food stamps), the National School Lunch Program, and the School Breakfast Program--have been remarkably successful at their core mission: reducing food insecurity among low-income children. Moreover, writes Craig Gundersen, SNAP in particular has also been…

The increasing world population means that there is a requirement to expand global food production. Looking at the Republic of Ireland as an example, the risks and opportunities associated with the expansion of food production are outlined, particularly in relation to zoonoses transmission. A One Health approach to sustainable food production is required to avert a potential public health problem associated with increased agricultural expansion.

Food security and health are complex interrelated issues. Individual characteristics exist within the physical and built environments. Title IV of the Food, Conservation, and Energy Act of 2008 is analyzed in terms of how it addresses systemic food insecurity and the opportunities the policy has for improving public health by increasing support for the availability of affordable local produce to low-income households. Structural changes need to occur for programs to be equitable, efficient, and effective. Interdisciplinary leadership within government agencies, school systems, social service agencies, health care agencies, and nonprofit networks is necessary to ensure food security and health for all Americans. Social work and public health practitioners have the opportunity to change the status quo, encourage community-level interventions, advocate for producers and consumers, and encourage more equitable distribution of food to create a healthier low-income population.

An estimated 30 percent of the global food supply is lost or wasted, as is about 40 percent of the US food supply. There are valuable synergies between efforts to reduce food loss and waste and those promoting public health. To demonstrate the potential impact of building upon these synergies, we present an analysis of policies and interventions addressing food loss and waste, food security, food safety, and nutrition. We characterize as opportunities the policies and interventions that promote synergistic relationships between goals in the fields of food loss and waste and of public health. We characterize as challenges the policies and interventions that may reduce food loss and waste but compromise public health, or improve public health but increase food loss and waste. Some interventions are both opportunities and challenges. With deliberate planning and action, challenges can often be addressed and turned into opportunities. In other cases, it may be necessary to strike a balance between potential benefit in one area and risk of harm in the other. To help policy makers make the best use of the opportunities while tackling the challenges, it is essential to consider public health in efforts to reduce food loss and waste.

The "organic food" market is the fastest growing food sector, yet it is unclear whether organically raised food is nutritionally superior to conventionally grown food and whether consuming organic food bestows health benefits. In order to evaluate potential health benefits of organic foods, we used the well-characterized fruit fly Drosophila melanogaster as a model system. Fruit flies were raised on a diets consisting of extracts of either conventionally or organically raised produce (bananas, potatoes, raisins, soy beans). Flies were then subjected to a variety of tests designed to assess overall fly health. Flies raised on diets made from organically grown produce had greater fertility and longevity. On certain food sources, greater activity and greater stress resistance was additionally observed, suggesting that organic food bestows positive effects on fly health. Our data show that Drosophila can be used as a convenient model system to experimentally test potential health effects of dietary components. Using this system, we provide evidence that organically raised food may provide animals with tangible benefits to overall health.

Background Foodborne disease is a significant problem worldwide. Research exploring sources of outbreaks indicates a pronounced role for food workers' improper health and hygiene practice. Objective To investigate food workers' perceptions of factors that impact proper food safety practice. Method Interviews with food service workers in Baltimore, MD, USA discussing food safety practices and factors that impact implementation in the workplace. A social ecological model organizes multiple levels of influence on health and hygiene behavior. Results Issues raised by interviewees include factors across the five levels of the social ecological model, and confirm findings from previous work. Interviews also reveal many factors not highlighted in prior work, including issues with food service policies and procedures, working conditions (e.g., pay and benefits), community resources, and state and federal policies. Conclusion Food safety interventions should adopt an ecological orientation that accounts for factors at multiple levels, including workers' social and structural context, that impact food safety practice.

The modern food system has evolved into one with highly inefficient activities, producing waste at each step of the food pathway from growing to consumption and disposal. The present challenge is to improve recyclability in the food system as a fundamental need for food and health security. This paper develops a methodological approach for a Food Recycling Index (FRI) as a tool to assess recyclability in the food system, to identify opportunities to reduce waste production and environmental contamination, and to provide a self-assessment tool for participants in the food system. The urban Taipei framework was used to evaluate resource and nutrient flow within the food consumption and waste management processes of the food system. A stepwise approach for a FRI is described: (1) identification of the major inputs and outputs in the food chain; (2) classification of inputs and outputs into modules (energy, water, nutrients, and contaminants); (3) assignment of semi-quantitative scores for each module and food system process using a matrix; (4) assessment for recycling status and recyclability potential; (5) conversion of scores into sub-indices; (6) derivation of an aggregate FRI. A FRI of 1.24 was obtained on the basis of data for kitchen waste management in Taipei, a score which encompasses absolute and relative values for a comprehensive interpretation. It is apparent that a FRI could evolve into a broader ecosystem concept with health relevance. Community end-users and policy planners can adopt this approach to improve food and health security.
Food and health security in North East Asia including South Korea, North Korea, China and Japan was compared. Because this region contains countries with many complex problems, it is worthwhile to study the current situation. With about 24% of the world's population, all North East Asian countries supply between 2400 and 3000 Kcal of energy. Regarding health status, two extreme problems exist. One is malnutrition in North Korea and China and the other is chronic degenerative disease in Japan, South Korea and China. Because quality, quantity and safety of the food supply have to be secured for health security, some topics are selected and discussed. 1) World food price can have an effect on food security for countries with a low food self sufficiency rate such as Japan and Korea; specially, for the urban poor. 2) Population aging can increase the number of aged people without food security. An aged population with less income and no support from their off-spring, because of disappearing traditional values, may have food insecurity. 3) Population growth and economic growth in this region may worsen food problems. Since a quarter of the world's population resides in this region, populations will continue to increase. With economic growth, people will consume more animal products. 4) Climate change generates food production problems. As the progress of industry continues, there will be less land for food and more pollutants in the environment. 5) Political instability will cause food insecurity and conflict will cause problems with regard to food aid.

A food can be regarded as 'functional' if it can demonstrate a beneficial efficacy on one or more target functions in the body in a convincing way. Beyond adequate nutritional qualities, functional foods should either improve the state of health and wellbeing and/or reduce the risk of disease. Functional foods that are marketed with claims of heart disease reduction focus primarily on the major risk factors, i.e. cholesterol, diabetes and hypertension. Some of the most innovative products are designed to be enriched with 'protective' ingredients, believed to reduce risk. They may contain, for example, soluble fibre (from oat and psyllium), useful both for lowering cholesterol and blood pressure, or fructans, effective in diabetes. Phytosterols and stanols lower LDL-cholesterol in a dose-dependent manner. Soya protein is more hypocholesterolaemic in subjects with very high initial cholesterol and recent data indicate also favourable activities in the metabolic syndrome. n-3 Fatty acids appear to exert significant hypotriacylglycerolaemic effects, possibly partly responsible for their preventive activity. Dark chocolate is gaining much attention for its multifunctional activities, useful both for the prevention of dyslipidaemia as well as hypertension. Finally, consensus opinions about tea and coffee have not emerged yet, and the benefits of vitamin E, garlic, fenugreek and policosanols in the management of dyslipidaemia and prevention of arterial disease are still controversial.

Inulin is a non-digestible carbohydrate that is contained in many vegetables, fruits and cereals. It is industrially produced from the chicory's root (Cichorium intybus) and it is widely used as ingredient in functional foods. Inulin and its derivate compounds (oligofructose, fructooligosaccharides) are usually called fructans, as they are basically based on linear fructose chains. This review presents a description of inulin and its most common derivate compounds: chemical structure, natural sources, physic-chemical properties, technological functionality, industrial manufacturing, analytical method for determination and health benefits: prebiotic, dietary fiber, low caloric value, hypoglycemic action, enhancement of calcium and magnesium bioavailability. Potential benefits: lipid parameters regulation, reduction of colon cancer risk and others, improvement of immune response, intestinal disorders protection. From technological point of view, these compounds exhibit a variety of properties: thickener, emulsifier, gel forming, sugar and fat substitute, humectant, freezing point depression. Inulin and derivates are been used in pharmaceutical, chemical and processing industry as technological additives and excipients. They are also been used for animal feeding. They are been considered as "bioactive" compounds to be proposed as future packaging material. Fructans are proposed to be classified as "functional fiber", according to recent concepts based on physiological effects on individuals. This review of inulin and its derivates was useful to show the broad boundaries of these compounds in the food industry and why they may be considered as key ingredients in the expanding functional food market.

A wide range of food-derived bioactive peptides have been shown to exert health-promoting actions and are therefore considered functional foods or nutraceuticals. Some of these actions are related to the maintenance, reinforcement or repairment of the intestinal barrier function (IBF) whose role is to selectively allow the absorption of water, nutrients and ions while preventing the influx of microorganisms from the intestinal lumen. Alterations in the IBF have been related to many disorders, such as inflammatory bowel disease or metabolic syndrome. Components of IBF are the intestinal epithelium, the mucus layer, secretory immunoglobulin A and cells of the innate and adaptive immune systems. Here we review the effects of food derived bioactive peptides on these IBF components. In vitro and in vivo effects, both in healthy and disease states, have been reviewed. Although limited, the available information indicates a potential for food-derived peptides to modify IBF and to contribute to disease treatment, but further research is needed to better isolate responsible peptides, and to help define their mode of action.

The functional foods and nutraceuticals market is growing at a rapid pace. Membrane processing offers several advantages over conventional methods for separation, fractionation, and recovery of those bioactive components. In this review, membrane applications of lipid-, carbohydrate-, and protein-based nutraceuticals and some minor bioactive components have been critically evaluated. Both non-porous and porous membranes were employed for lipid-based nutraceuticals separations. The use of non-porous membranes together with non-aqueous solvents brought about the impact of solution-diffusion theory on transport through membranes. Both organic and inorganic membranes gave encouraging results for the recovery of lipid components with single- and/or multi-stage membrane processing. Two-stage ultrafiltration (UF)-nanofiltration (NF) systems with polymeric membranes provided an efficient approach for the removal of high- and low-molecular weight (MW) unwanted components resulting in higher purity oligosaccharides in the NF retentate. The charged nature of protein-based nutraceutical components had a major effect on their separation. Operating at optimizal pH levels was critical for fractionation, especially for low MW peptide hydrolysates. Processing of minor components such as polyphenols, utilized all types of porous membranes from prefiltration to concentration stages. Coupling of membrane separation and supercritical fluid technologies would combine unique advantages of each process resulting in a novel separation technology offering great potential for the nutraceutical and functional food industry.

One of the factors that is believed to contribute to Japanese longevity is their dietary life, which is unique and distinct from Westerners. However, there has been no study that examined whether Japanese food in itself is effective for health maintenance. Therefore, we investigated in rats whether Japanese food is beneficial to health maintenance compared with American food. As a result, we revealed that modern Japanese food is useful for health maintenance compared with modern American food. We subsequently investigated the health benefits of Japanese food from different eras. The menus of Japanese foods from 4 different years, 2005, 1990, 1975 and 1960 were prepared, cooked, and powderized. Each of the Japanese foods was provided to mice. We found that the Japanese food from 1975 exhibited health benefits with respect to the stages of growth, adolescence, maturity and old age. Furthermore, we focused on fish oil, which is one of the beneficial ingredients of Japanese food, and investigated the effect of its long-term intake on lifespan in mice. Surprisingly, long-term intake of large amounts of fish oil shortened the lifespan of these mice. By contrast, intake of small amounts of fish oil with antioxidants extended the lifespan. Moreover, while intake of large amounts of fish oil also shortened the lifespan of Caenorhabditis elegans (C. elegans), intake of small amounts of fish oil extended the lifespan. Thus, it was suggested that even when foods have been reported to have health benefits, ingestion of large amounts of individual foods is undesirable for health maintenance.

Insights into the use of health-related information on foods are important for planning studies about the effects of such information on the consumer’s understanding, purchasing, and consumption of foods, and also support further food policy decisions. We tested the use of sales data for weighting consumers’ exposure to health-related labeling information in the Slovenian food supply. Food labeling data were collected from 6342 pre-packed foods available in four different food stores in Slovenia. Consumers’ exposure was calculated as the percentage of available food products with particular food information in the food category. In addition, 12-month sales data were used to calculate sales weighted exposure as a percentage of sold food products with certain food information in the food category. The consumer’s in-store and sales-weighted exposure to nutrition claims was 37% and 45%, respectively. Exposure to health claims was much lower (13%, 11% when sales-weighted). Health claims were mainly found in the form of general non-specific claims or function claims, while children’s development and reduction of disease risk claims were present on only 0.1% and 0.2% of the investigated foods, respectively. Sales data were found very useful for establishing a reliable estimation of consumers’ exposure to information provided on food labels. The high penetration of health-related information on food labels indicates that careful regulation of this area is appropriate. Further studies should focus on assessing the nutritional quality of foods labeled with nutrition and health claims, and understanding the importance of such labeling techniques for consumers’ food preferences and choices.

Previous research on health and life insurers' financial investments has highlighted the tension between profit maximization and the public good. We ascertained health and life insurance firms' holdings in the fast food industry, an industry that is increasingly understood to negatively impact public health. Insurers own $1.88 billion of stock in the 5 leading fast food companies. We argue that insurers ought to be held to a higher standard of corporate responsibility, and we offer potential solutions.

Deep ocean water (DOW) is obtained from 600 m below the sea surface. In recent years, DOW has been applied in the development of fermentation biotechnologies and functional foods. DOW is rich in trace minerals, comprises multiple physiological and health functions, and is able to promote microbe growth; therefore, the application of DOW directly benefits the development of the fermentation industry and functional foods. This study integrated the current health functions and applications of DOW with the latest results from studies related to fermentation biotechnology. Subsequently, the influence of applying DOW in fermented functional food development and the effects in health function improvements were summarized. According to the previous studies, the main reasons for the increased effect of fermented functional foods through the application of DOW are increased generation of functional metabolite contents in the microbes, intrinsic health functions of DOW, and the microbial use of mechanisms of converting the absorbed inorganic ions into highly bioavailable organic ions for the human body. These combined advantages not only enhance the health functions of fermentation products but also provide fermentation products with the intrinsic health functions of DOW.
The safety guideline for voluntary inspections on the ingredients used for capsulated or pellet food, announced by the director of the department of food safety of the Ministry of Health, Labor and Welfare on February 1, 2008 states that "how to guarantee the origin" is the top priority to ensure safety. However, in the course of our continuous investigation of the origin of natural products, the ingredients of some health food products such as chondroitin sulfate, white kwao keur (Pueraria candollei var. mirifica) and black cohosh did not originate from the labeled material. The usage of the correct origin is the fist step for the quality assurance of "health food". Therefore, we believe that regulatory requirements for accurately indicating the origin of "health foods" and effective enforcement of these requirements are needed.

Professional health bodies such as the World Health Organization (WHO), the American Academy of Pediatrics (AAP), and the U.S. Department of Health and Human Services (HHS) recommend breast milk as the sole source of food during the first year of life. This position recognizes human milk as being uniquely suited for infant nutrition. Nonetheless, most neonates in the West are fed alternatives by 6 months of age. Although inferior to human milk in most aspects, infant formulas are able to promote effective growth and development. However, while breast-fed infants feature a microbiota dominated by bifidobacteria, the bacterial flora of formula-fed infants is usually heterogeneous with comparatively lower levels of bifidobacteria. Thus, the objective of any infant food manufacturer is to prepare a product that results in a formula-fed infant developing a breast-fed infant-like microbiota. The goal of this focused review is to discuss the structure, synthesis, and function of carbohydrate additives that play a role in governing the composition of the infant microbiome and have other health benefits.

Non-communicable diseases (NCD) are a major and increasing contributor to morbidity and mortality in developed and developing countries. Much of the chronic disease burden is preventable through modification of lifestyle behaviours, and increased attention is being focused on identifying and implementing effective preventative health strategies. Nutrition has been identified as a major modifiable determinant of NCD. The recent merging of health economics and nutritional sciences to form the nascent discipline of nutrition economics aims to assess the impact of diet on health and disease prevention, and to evaluate options for changing dietary choices, while incorporating an understanding of the immediate impacts and downstream consequences. In short, nutrition economics allows for generation of policy-relevant evidence, and as such the discipline is a crucial partner in achieving better population nutritional status and improvements in public health and wellness. The objective of the present paper is to summarise presentations made at a satellite symposium held during the 11th European Nutrition Conference, 28 October 2011, where the role of nutrition and its potential to reduce the public health burden through alleviating undernutrition and nutrition deficiencies, promoting better-quality diets and incorporating a role for functional foods were discussed.

Background: Anthropogenic climate change will affect global food production, with uncertain consequences for human health in developed countries. Objectives: We investigated the potential impact of climate change on food security (nutrition and food safety) and the implications for human health in developed countries. Methods: Expert input and structured literature searches were conducted and synthesized to produce overall assessments of the likely impacts of climate change on global food production and recommendations for future research and policy changes. Results: Increasing food prices may lower the nutritional quality of dietary intakes, exacerbate obesity, and amplify health inequalities. Altered conditions for food production may result in emerging pathogens, new crop and livestock species, and altered use of pesticides and veterinary medicines, and affect the main transfer mechanisms through which contaminants move from the environment into food. All these have implications for food safety and the nutritional content of food. Climate change mitigation may increase consumption of foods whose production reduces greenhouse gas emissions. Impacts may include reduced red meat consumption (with positive effects on saturated fat, but negative impacts on zinc and iron intake) and reduced winter fruit and vegetable consumption. Developed countries have complex structures in place that may be used to adapt to the food safety consequences of climate change, although their effectiveness will vary between countries, and the ability to respond to nutritional challenges is less certain. Conclusions: Climate change will have notable impacts upon nutrition and food safety in developed countries, but further research is necessary to accurately quantify these impacts. Uncertainty about future impacts, coupled with evidence that climate change may lead to more variable food quality, emphasizes the need to maintain and strengthen existing structures and policies to regulate

Increasing attention has been recently paid to the toxicity of additives used in food. The European Parliament and the Council published the REGULATION (EC) No. 1333/2008 on food additives establishing that the toxicity of food additives evaluated before 20th January 2009 must be re-evaluated by European Food Safety Authority (EFSA). The aim of this review is to survey current knowledge specifically on the toxicity issues of synthetic food colorants using official reports published by the EFSA and other available studies published since the respective report. Synthetic colorants described are Tartrazine, Quinoline Yellow, Sunset Yellow, Azorubine, Ponceau 4R, Erythrosine, Allura Red, Patent Blue, Indigo Carmine, Brilliant Blue FCF, Green S, Brilliant Black and Brown HT. Moreover, a summary of evidence on possible detrimental effects of colorant mixes on children's behaviour is provided and future research directions are outlined.

Trophic interactions are central to ecosystem functioning, but the link between food web structure and ecosystem functioning remains obscure. Regularities (i.e. consistent patterns) in food web structure suggest the possibility of regularities in ecosystem functioning, which might be used to relate structure to function. We introduce a novel, genetic algorithm approach to simulate food webs with maximized throughput (a proxy for ecosystem functioning) and compare the structure of these simulated food webs to real empirical food webs using common metrics of food web structure. We repeat this analysis using robustness to secondary extinctions (a proxy for ecosystem resilience) instead of throughput to determine the relative contributions of ecosystem functioning and ecosystem resilience to food web structure. Simulated food webs that maximized robustness were similar to real food webs when connectance (i.e. levels of interaction across the food web) was high, but this result did not extend to food webs with low connectance. Simulated food webs that maximized throughput or a combination of throughput and robustness were not similar to any real food webs. Simulated maximum-throughput food webs differed markedly from maximum-robustness food webs, which suggests that maximizing different ecological functions can generate distinct food web structures. Based on our results, food web structure would appear to have a stronger relationship with ecosystem resilience than with ecosystem throughput. Our genetic algorithm approach is general and is well suited to large, realistically complex food webs. Genetic algorithms can incorporate constraints on structure and can generate outputs that can be compared directly to empirical data. Our method can be used to explore a range of maximization or minimization hypotheses, providing new perspectives on the links between structure and function in ecological systems.

Kimchi is a traditional Korean food manufactured by fermenting vegetables with probiotic lactic acid bacteria (LAB). Many bacteria are involved in the fermentation of kimchi, but LAB become dominant while the putrefactive bacteria are suppressed during salting of baechu cabbage and the fermentation. The addition of other subingredients and formation of fermentation byproducts of LAB promote the fermentation process of LAB to eventually lead to eradication of putrefactive- and pathogenic bacteria, and also increase the functionalities of kimchi. Accordingly, kimchi can be considered a vegetable probiotic food that contributes health benefits in a similar manner as yogurt as a dairy probiotic food. Further, the major ingredients of kimchi are cruciferous vegetables; and other healthy functional foods such as garlic, ginger, red pepper powder, and so on are added to kimchi as subingredients. As all of these ingredients undergo fermentation by LAB, kimchi is regarded as a source of LAB; and the fermentative byproducts from the functional ingredients significantly boost its functionality. Because kimchi is both tasty and highly functional, it is typically served with steamed rice at every Korean meal. Health functionality of kimchi, based upon our research and that of other, includes anticancer, antiobesity, anticonstipation, colorectal health promotion, probiotic properties, cholesterol reduction, fibrolytic effect, antioxidative and antiaging properties, brain health promotion, immune promotion, and skin health promotion. In this review we describe the method of kimchi manufacture, fermentation, health functionalities of kimchi and the probiotic properties of its LAB.

With ever-increasing frequency, consumers are seeking information on the foods they eat. Food labels are an important source of this type of information, and the Codex Alimentarius, created by the World Health Organization and the Food and Agriculture Organization of the United Nations, provides a global reference for coordinated food quality and identification standards. The Codex Alimentarius agenda includes nutritional information and "health claims," which are defined as any representation that states, suggests, or implies that a relationship exists between a food or a constituent of that food and health. Although food labeling seems to effectively assist consumers in choosing among processed foods, consumers are not always capable of reading or interpreting nutritional information correctly, so health claims may allow for more precise decision-making for these products. The present paper examines the use of health claims in countries and regions that have already implemented this type of regulation (Brazil, Chile, Canada, United States of America, the European Union, and Japan).

Whereas sub-Saharan Africa’s (SSA) water scarcity, food, nutrition and health challenges are well-documented, efforts to address them have often been disconnected. Given that the region continues to be affected by poverty and food and nutrition insecurity at national and household levels, there is a need for a paradigm shift in order to effectively deliver on the twin challenges of food and nutrition security under conditions of water scarcity. There is a need to link water use in agriculture to achieve food and nutrition security outcomes for improved human health and well-being. Currently, there are no explicit linkages between water, agriculture, nutrition and health owing to uncoordinated efforts between agricultural and nutrition scientists. There is also a need to develop and promote the use of metrics that capture aspects of water, agriculture, food and nutrition. This review identified nutritional water productivity as a suitable index for measuring the impact of a water-food-nutrition-health nexus. Socio-economic factors are also considered as they influence food choices in rural communities. An argument for the need to utilise the region’s agrobiodiversity for addressing dietary quality and diversity was established. It is concluded that a model for improving nutrition and health of poor rural communities based on the water-food-nutrition-health nexus is possible. PMID:26751464

Eating causes up to a quarter of premature deaths from chronic diseases in Europe through poor diet and excess consumption. FAHRE (Food and Health Research in Europe) was funded to determine needs and gaps in research structures and programmes. Most food research links towards agriculture and the environmental sciences, whereas most health research links towards clinical diseases, biochemical pathways and biology. Research on food and health together includes food safety research addressing biological and chemical contaminants, and biotechnology research supporting clinical nutrition. Research for healthy eating must draw on social and behavioural sciences for studies of policy, regulation and interventions. The food industry, across production, retail and catering, must be part of the research programme, and civil society. Better coordination and improved levels of funding are needed in the coming European research programme 'Horizon 2020', and national programmes linked in the Joint Programming Initiative. Transforming the research agenda can give great benefits to Europe's citizens.

Dietary supplements are used by more than one-half of the adult US population. In contrast to pharmaceuticals, dietary supplements may be sold in the United States with little regulation other than listing of ingredients and the potential health benefits. By contrast, herbal products in Germany are carefully regulated by the same standards as drugs, and efforts are under way to standardize their regulation in the entire European Union. Most herbal users do not inform their physicians that they are taking these supplements, and most physicians do not inquire. Although some herbal products have clinically proven benefits, it is increasingly apparent that many contain potentially toxic substances, particularly in relation to interactions with drugs. Hence, it is essential that practicing physicians develop a working knowledge of herbals-specifically, about claims for their usage and potential or proven efficacies and toxicities-and that they incorporate such knowledge into the evaluation and management of their patients. By contrast, functional foods-integral components of the diet that are understood to contribute added health benefits-are the subject of intense and widespread research in food and nutritional science. Examples include many polyphenolic substances, carotenoids, soy isoflavones, fish oils, and components of nuts that possess antioxidant and other properties that decrease the risk of vascular diseases and cancer. Practicing physicians are advised to stay abreast of these emerging findings in order to best advise their patients on the value of health-promoting diets in disease prevention.

During the last 6 y, the European Union has undergone a profound qualitative change in the focus on food safety problems. In 1997, nine new scientific committees were created, including the Scientific Committee on Food (SCF) and the Scientific Steering Committee (SSC), and were put under the auspices of the Directorate General in charge of defending consumer interests and health. The process is foreseen to be completed by the incorporation in 2003 of all food safety activities of these committees into the European Food Safety Authority (EFSA). Among the immediate challenges in the near future are the scientific and technological developments and the regulatory measures for the so-called 'functional foods', which can positively affect the health and well-being of consumers. Functional foods are a recent phenomenon in Europe and are, as yet, not covered by any specific legislation. The two key aspects in the evaluation of functional foods are safety and efficacy. Whereas safety can be covered under different legislative umbrellas such as novel foods (NFs), foods for particular nutritional purposes, supplements, additives and others, the issue of evaluation of their efficacy is only at a very early stage since the criteria to establish the validity of 'health claims' has not been clearly addressed at a European level.

It was mainly the advances in understanding the relationship between nutrition and health that resulted in the development of the concept of functional foods, which means a practical and new approach to achieve optimal health status by promoting the state of well-being and possibly reducing the risk of disease. Functional foods are found virtually in all food categories, however products are not homogeneously scattered over all segments of the growing market. The development and commerce of these products is rather complex, expensive and risky, as special requirements should be answered. Besides potential technological obstacles, legislative aspects, as well as consumer demands need to be taken into consideration when developing functional food. In particular, consumer acceptance has been recognized as a key factor to successfully negotiate market opportunities. This paper offers a brief overview of the current functional food market situation in USA, Japan and some European countries completed with some comments on functional food future potential. It explores the main challenges of such product development focusing on the different factors determining the acceptance of functional food. Furthermore it discusses some prominent types of these food products currently on the market.

Consumption of takeaway and fast food continues to increase in Western societies and is particularly widespread among adolescents. Since food is known to play an important role in both the development and prevention of many diseases, there is no doubt that the observed changes in dietary patterns affect the quality of the diet as well as public health. The present review examines the nutritional characteristics of takeaway and fast food items, including their energy density, total fat, and saturated and trans fatty acid content. It also reports on the association between the consumption of such foods and health outcomes. While the available evidence suggests the nutrient profiles of takeaway and fast foods may contribute to a variety of negative health outcomes, findings on the specific effects of their consumption on health are currently limited and, in recent years, changes have been taking place that are designed to improve them. Therefore, more studies should be directed at gaining a firmer understanding of the nutrition and health consequences of eating takeaway and fast foods and determining the best strategy to reduce any negative impact their consumption may have on public health.
A new oat food ingredient, containing 20% to 30% soluble beta-glucan, was obtained from oat bran by using natural treatments of heat and shear processing. The product is useful for reducing calories in foods while simultaneously adding health promoting benefits from its beta-glucan. It was evaluat...

One of the mechanisms for food alerts management is the rapid interchange of information so that the response takes place the sooner and the impact of the risk can be diminished. The structure of information transmitted, the priority and categorization of the risk, the differentiated treatment of the information, the decision on who must be informed, the confidentiality of information transmitted, and evaluations of it, the reduction of the abuse or the use of precautionary principle are questions that can serve as guidelines for an analysis of the different systems and provide a comparison perspective that can help to improve the exchange of information on risks in the present day global market of foods. The main goal of this article is to provide a proposal for improvement in the food alerts management system in our country through an analysis and comparison of the essential elements of different systems in our context.

A number of naturally occurring dietary substances may exert physiological benefits. The production of enhanced levels or particularly tailored versions of such candidate functional compounds can be targeted by enzymatic catalysis. The recent literature contains examples of enhancing bioavailability of iron via enzyme-catalyzed degradation of phytate in wheat bran, increasing diacyl-glycerol and conjugated linoleic acid levels by lipase action, enhancing the absorption of the citrus flavonoid hesperetin via rhamnosidase treatment, and obtaining solubilized dietary fiber via enzymatic modification of potato starch processing residues. Such targeted enzyme-catalyzed reactions provide new invention opportunities for designing functional foods with significant health benefits. The provision of well-defined naturally structured compounds can, moreover, assist in obtaining the much-needed improved understanding of the physiological benefits of complex natural substances.

This article describes the legislation that is relevant in the marketing of functional foods in the European Union (EU), how this legislation was developed as well as some practical consequences for manufacturers, marketers and consumers. It also addresses some concrete examples of how the EU's safety requirements for food products have impacted a range of product categories. In the late nineties, research into functional ingredients was showing promising prospects for the use of such ingredients in foodstuffs. Due mainly to safety concerns, these new scientific developments were accompanied by an urgent call for legislation. The European Commission 2000 White Paper on Food Safety announced some 80 proposals for new and improved legislation in this field. Among others, it foresaw the establishment of a General Food Law Regulation, laying down the principles of food law and the creation of an independent Food Authority endowed with the task of giving scientific advice on issues based upon scientific risk assessment with clearly separated responsibilities for risk assessment, risk management and risk communication. Since then, more than 90% of the White Paper proposals have been implemented. However, there is not, as such, a regulatory framework for 'functional foods' or 'nutraceuticals' in EU Food Law. The rules to be applied are numerous and depend on the nature of the foodstuff. The rules of the general food law Regulation are applicable to all foods. In addition, legislation on dietetic foods, on food supplements or on novel foods may also be applicable to functional foods depending on the nature of the product and on their use. Finally, the two proposals on nutrition and health claims and on the addition of vitamins and minerals and other substances to foods, which are currently in the legislative process, will also be an important factor in the future marketing of 'nutraceuticals' in Europe. The cornerstone of EU legislation on food products, including

This study investigates the effect of socioeconomic and demographic variables, nutrition and health related factors, attitudes, and use of nutritional labels on consumers' choice for healthier food products. Seven equations are estimated representing different food types: luncheon meat, milk, cheese, ice cream, salad dressing, dessert, and meats. The results generally indicate that individuals who are less likely to choose a healthier alternative of a food product include: blacks, younger individuals, males, those with smaller households, smokers, those who take less exercise, those who are not on a special diet, those who are less aware about the linkage between diet and disease, those who put more importance on taste when food shopping, and those who less frequently use nutrition panels and labels that describe health benefits on food packages.

Around the world, fermentation of foods has been adopted over many generations, primarily due to their commercial significance with enriched flavors and high-profile nutrients. The increasing application of fermented foods is further promoted by recent evidence on their health benefits, beyond the traditionally recognized effects on the digestive system. With recent advances in the understanding of gut-brain interactions, there have also been reports suggesting the fermented food’s efficacy, particularly for cognitive function improvements. These results are strengthened by the proposed biological effects of fermented foods, including neuroprotection against neurotoxicity and reactive oxygen species. This paper reviews the beneficial health effects of fermented foods with particular emphasis on cognitive enhancement and neuroprotective effects. With an extensive review of fermented foods and their potential cognitive benefits, this paper may promote commercially feasible applications of fermented foods as natural remedies to cognitive problems.

Organic solvent residue levels in "Existing Food Additives" (n=145), health food materials (n=23), and commercial health food products (n=19) were surveyed. Ethanol was the dominant solvent found in the samples, suggesting its use in the manufacturing process. Methanol, acetone, 2-propanol and ethyl acetate was also found. No residual solvent exceeded the limits set by the Food Sanitation Law.

The study of controversies is a methodological tool that generates knowledge about the social and political dimensions of science. This approach can be used to understand and explore the topic of organic foods. The present study aimed to analyze the controversies regarding the status of organic foods. We carried out a review of studies published since 1990 in three websites: International Foundation for Organic Agriculture, Soil Association, and Food and Agriculture Organization. The following controversies were identified: 1) effects on human health of the presence of chemical contaminants in organic foods; 2) the quality of organic foods as compared to conventionally grown foods; and 3) price of organic foods. Based on this review, it is possible to conclude that, even though organic foods stand out for their low toxicity, higher durability, and nutritional content of some items, more comparative studies are required to confirm the nutritional superiority of organic foods and to solve the controversies. The discussion must be contextualized within a broad spectrum of health promotion, in which organic farming appears associated with the support for small farming, biodiversity, and local sustainable development, so as to increase offer and demand for organic products at fair prices for individual and institutional consumers.

Scientific and technological developments in the agricultural sectors in the recent past has resulted in increased food production and at the same time led to certain public health concerns. Unseasonal rains at the time of harvest and improper post harvest technology often results in agricultural commodities being contaminated with certain fungi and results in the production of mycotoxins. Consumption of such commodities has resulted in human disease outbreaks. Naturally occurring toxins, inherently present in foods and either consumed as such or mixed up with grains, had been responsible for disease outbreaks. Other possible causes of health concern include the application of various agrochemicals such as pesticides and the use of antibiotics in aquaculture and veterinary practices. Foodborne pathogens entering the food chain during both traditional and organic agriculture pose a challenge to public health. Modern biotechnology, producing genetically modified foods, if not regulated appropriately could pose dangers to human health. Use of various integrated food management systems like the Hazard Analysis and critical control system approach for risk prevention, monitoring and control of food hazards are being emphasized with globalization to minimise the danger posed to human health from improper agricultural practices.
Dry beans, peas, and lentils (pulses) are a principle source of protein in many parts of the world and have long been known to be healthy foods. Their use in traditional ethnic foods is well established; however, unlike grains, meat, dairy products, and other vegetables, they are not universally pre...
Background Consumption of high calorie junk foods has increased recently, especially among young adults and higher intake may cause weight gain. There is a need to develop public health approaches to motivate people to reduce their intake of junk food. Objective To assess the effect of health and social norm messages on high calorie snack food intake (a type of junk food) as a function of usual intake of junk food. Design In a between-subjects design, 129 young adults (45 men and 84 women, mean age = 22.4 years, SD = 4.5) were assigned to one of three conditions: 1) a social norm condition, in which participants saw a message about the junk food eating habits of others; 2) a health condition, in which participants saw a message outlining the health benefits of reducing junk food consumption and; 3) a control condition, in which participants saw a non-food related message. After exposure to the poster messages, participants consumed a snack and the choice and amount of snack food consumed was examined covertly. We also examined whether usual intake of junk food moderated the effect of message type on high calorie snack food intake. Results The amount of high calorie snack food consumed was significantly lower in both the health and the social norm message condition compared with the control message condition (36% and 28%, both p < 0.05). There was no significant difference in snack food or energy intake between the health and social norm message conditions. There was no evidence that the effect of the messages depended upon usual consumption of junk food. Conclusions Messages about the health effects of junk food and social normative messages about intake of junk food can motivate people to reduce their consumption of high calorie snack food.

Because of the beneficial effects to health functional foods are important elements of health promotion. The positive effect of the functional components should be based on scientific evidence-based. In addition to the traditional food processing technology new technologies have appeared, e.g. microencapsulation, edible coatings and orodispersible films, nano-technology, vacuum impregnation. In the present study, probiotics and the structure, the production and the impact of prebiotic functional cereals are discussed in more detail. In addition to their numerous advantages in connection with the safe application, several questions arise because of inadequate quality control measures prior to coming onto the market.
Background This paper explores the nature of food and plants and their meanings in a British Bengali urban context. It focuses on the nature of plants and food in terms of their role in home making, transnational connections, generational change and concepts of health. Methods An ethnographic approach to the research was taken, specific methods included participant observation, focus group discussions and semi-structured interviews. Thirty women of Bengali origin were mostly composed of “mother” and “daughter” pairs. The mothers were over 45 years old and had migrated from Bangladesh as adults and their grown-up daughters grew up in the UK. Results Food and plants play an important role in the construction of home “here” (London) while continuing to connect people to home “there” (Sylhet). This role, however, changes and is re-defined across generations. Looking at perceptions of “healthy” and “unhealthy” food, particularly in the context of Bengali food, multiple views of what constitutes “healthy” food exist. However, there appeared to be little two-way dialogue about this concept between the research participants and health professionals. This seems to be based on “cultural” and power differences that need to be addressed for a meaningful dialogue to occur. Conclusion In summary, this paper argues that while food is critical to the familial spaces of home (both locally and globally), it is defined by a complex interplay of actors and wider meanings as illustrated by concepts of health and what constitutes Bengali food. Therefore, we call for greater dialogue between health professionals and those they interact with, to allow for an enhanced appreciation of the dynamic nature of food and plants and the diverse perceptions of the role that they play in promoting health.

There is increasing recognition that the nutrition transition sweeping the world’s cities is multifaceted. Urban food and nutrition systems are beginning to share similar features, including an increase in dietary diversity, a convergence toward “Western-style” diets rich in fat and refined carbohydrate and within-country bifurcation of food supplies and dietary conventions. Unequal access to the available dietary diversity, calories, and gastronomically satisfying eating experience leads to nutritional inequalities and diet-related health inequities in rich and poor cities alike. Understanding the determinants of inequalities in food security and nutritional quality is a precondition for developing preventive policy responses. Finding common solutions to under- and overnutrition is required, the first step of which is poverty eradication through creating livelihood strategies. In many cities, thousands of positions of paid employment could be created through the establishment of sustainable and self-sufficient local food systems, including urban agriculture and food processing initiatives, food distribution centers, healthy food market services, and urban planning that provides for multiple modes of transport to food outlets. Greater engagement with the food supply may dispel many of the food anxieties affluent consumers are experiencing. PMID:17401697

Homeostasis is the basis of modern medicine and allostasis, a further elaboration of homeostasis, has been defined as stability through change, which was later modified to predictive reference resetting. It has been suggested that pleasure is related to salience (behavioral relevance), and withdrawal has been linked to allostasis in addictive types. The question arises how the clinical and neural signatures of pleasure, salience, allostasis and withdrawal relate, both in a non-addicted and addicted state. Resting state EEGs were performed in 66 people, involving a food-addicted obese group, a non-food addicted obese group and a lean control group. Correlation analyses were performed on behavioral data, and correlation, comparative and conjunction analyses were performed to extract electrophysiological relationships between pleasure, salience, allostasis and withdrawal. Pleasure/liking seems to be the phenomenological expression that enough salient stimuli are obtained, and withdrawal can be seen as a motivational incentive because due to allostatic reference resetting, more stimuli are required. In addition, in contrast to non-addiction, a pathological, non-adaptive salience attached to food results in withdrawal mediated through persistent allostatic reference resetting. PMID:27876789

Instruments have been developed and validated for the measurement of health-related quality of life in patients with food allergy. This guideline has been prepared by the European Academy of Allergy and Clinical Immunology's (EAACI) Guidelines for Food Allergy and Anaphylaxis Group. It draws on a systematic review of the literature on quality of life instruments for food allergy and the Appraisal of Guidelines for Research & Evaluation (AGREE II) guideline development process. Guidance is provided on the use of such instruments in research, and the current limitations of their use in clinical practice are described. Gaps in current knowledge as well as areas of future interest are also discussed. This document is relevant to healthcare workers dealing with food-allergic patients, scientists engaging in food allergy research and policy makers involved in regulatory aspects concerning food allergy and safety.
Epidemiological studies of bioactive compounds from plant-based foods have consistently pointed to undisputed benefits of consumption of plant-based foods on human health particularly regarding cardiovascular diseases and cancers. However, in order to attain the dosage required from these studies, p...
It is amazing to see how much the approach of the food risk analysis evolved in the recent years. For half a century and the birth of the risk assessment methodology in the food domain, only no appreciable health risk was considered acceptable by the manager. This is the vocabulary used in the case of a voluntary, deliberated human action, as the use of food additives (definition of ADI). In the case of risks not resulting from such an action, as that of the presence of contaminants, the risk assessor allocates provisional tolerable daily, weekly or monthly intake that are the basis for regulation. This vocabulary is in agreement with the objective which consists in approaching closer possible of the zero risk which is the wish of a majority of the consumers. Some years ago, the risk managers insisted to obtain from the assessors as often as possible a quantitative risk evaluation. More recently even, the managers would like to decide on the basis of a balance of risk and benefit acceptable for management purposes. Finally, they hope that general principles and tools will be available for conducting a quantitative risk-benefit analysis for foods and food ingredients. What is possible in the case of functional foods (FF)? Based on the definition of FF proposed in the programme FUFOSE, one has to distinguish between different situations in order to assess the risk: that of a micro-, that of a macro-component or that of a whole food. These situations have been clearly described in the document resulting from FOSIE. The standardized methodology relevant to assess micro-components is not well adapted to the assessment of whole food. Concepts of substantial equivalence and of history of safe use could be useful tools in this case. However, quantitative risk assessment remains a very difficult exercise. If a process for the assessment of health benefit of FF has been proposed as an outcome of the PASSCLAIM action, the quantification of this benefit needs adequate tools
Over the past century, a major shift in North American food practices has been taking place. However, the literature on this topic is lacking in several areas. Some available research on food and cooking practices in the current context is presented, with a focus on how these are affecting health and how they might be contributing to health inequalities within the population. First, cooking and cooking skills are examined, along with the ambiguities related to terms associated with cooking in the research literature. Food choice, cooking, and health are described, particularly in relation to economic factors that may lead to health inequalities within the population. The importance of developing an understanding of factors within the wider food system as part of food choice and cooking skills is presented, and gaps in the research literature are examined and areas for future research are presented. Cooking practices are not well studied but are important to an understanding of human nutritional health as it relates to cultural, environmental, and economic factors.
We examined the effects of spices and herbs on Candida albicans to develop therapeutic tools against oral diseases such as oral candidiasis. C. albicans, a dimorphic fungus, is a component of the healthy human microbial flora. However, the excessive overgrowth of C. albicans causes oral candidiasis, and the symptoms, accompanied by severe inflammation, reduce the quality of life of elderly people. We found that spices such as clove (Syzygium aromaticum) and cassia (Cinnamomum aromaticum) exhibit inhibitory activity against Candida mycelial growth and show therapeutic efficacy in a murine oral candidiasis model. Our studies also demonstrated that the inhibitory activity of cinnamaldehyde was strengthened in parallel with a prolonged treatment time. Furthermore, when cinnamaldehyde in combination with methylcellulose was administered to the model mice, the therapeutic effect was potentiated. Here, we summarize up-to-date findings on how to use spices and herbs on a daily basis to improve or prevent oral problems such as oral candidiasis with the presentation of our recent data.

Background This is a 2-year study to assess the early impacts of a new grocery store intervention in a former food desert. Objective The purpose of the study is to understand the early health effects of the introduction of a large-scale food and nutrition-focused community-based population health intervention, the Good Food Junction (GFJ) Cooperative Store, in a geographically bounded group of socially disadvantaged neighborhoods (the “core neighborhoods”) in a midsized Canadian city. The GFJ grocery store was tasked with improving the access of residents to healthy, affordable food. The 5 research questions are: (1) What is the awareness and perception of the GFJ store among residents of the core neighborhoods? (2) Are there differences in awareness and perception among those who do and do not shop at the GFJ? (3) Will healthy food purchasing at the GFJ by residents of the core neighborhoods change over time, and what purchases are these individuals making at this store? (4) What early impact(s) will the GFJ have on key health-related outcomes (such as household food security status, vegetable and fruit intake, key aspects of self-reported mental health, self-reported health)? and (5) Are the effects of the intervention seen for specific vulnerable population groups, such as Aboriginal people, seniors (65 years old or older) and new immigrants (settled in Saskatoon for less than 5 years)? Methods The research project examined initial impacts of the GFJ on the health of the residents in surrounding neighborhoods through a door-to-door cross-sectional survey of food access and household demographics; an examination of GFJ sales data by location of shoppers' residences; and a 1-year, 3-time-point longitudinal study of self-reported health of GFJ shoppers. Results Analyses are on-going, but preliminary results show that shoppers are using the store for its intended purpose, which is to improve access to healthy food in a former food desert. Conclusions To our

Regulation on nutrition and health claims number (EC) No. 1924/2006 came into force in the European Union (EU) in 2007. The Regulation aims to ensure that claims are truthful and do not mislead consumers. It also aims to stimulate innovation to produce healthier food products in the food industry. Nutrition claims are defined in an annex to the Regulation that states the wording of permitted claims and the conditions of use. The scientific support for potential health claims is being assessed by the European Food Safety Authority (EFSA), but consideration of other aspects and the final decision to accept or reject a claim lies with the European Commission. The final list of approved health claims was due to be published in early 2010, but work is behind schedule, and therefore decisions are being published in batches; the first batch of Article 13 claims based on generally accepted science was published in October 2009. Food composition data are vital in making accurate claims on food as the amount of the nutrient or food component in question must be defined. It is also important that the composition of a particular food or food category has been sufficiently defined in order for a health claim pertaining to this to be approved. In addition, to prevent claims being made on foods with a less healthy profile, nutrient profiles are being developed that will specify threshold amounts of saturated fat, sodium and sugar present in any product bearing a nutrition or health claim, and thus the composition of a food will be critical in determining whether it is eligible to carry a claim. Therefore, the access that the European Food Information Resource (EuroFIR) will provide to pan-European food composition data will be of great importance in making the Regulation workable. EuroFIR has been actively involved in EFSA's work on nutrient profiles, supplying data that have been used to develop the current profiling model. It is hoped that the EuroFIR Network and the not

Food selection, decisions about which foods to eat, is a ubiquitous part of our everyday lives. The aim of this research was to investigate the role of taste versus health perceptions in 4- and 6-year-old children's food selection. In this study, children and young adults were asked to rate the health and presumed taste of foods. Participants were also asked to indicate whether they would eat these foods in a food selection task. Overall, the results showed that taste was a strong predictor of individuals' food selection above and beyond the variance associated with age, health ratings, and interactions between age and presumed taste ratings as well as age and health ratings. These results contribute to our understanding of children's food selection, and the relative importance of a food's taste versus health in the development of these decisions.

The major food safety risks are not eating a healthy diet, and failure to avoid foodborne illness. Over one billion people in the world suffer from food insecurity and malnutrition. Nutritionally enhanced transgenic crops such as Golden Rice are one potential strategy for reducing malnutrition in the world. Transgenic crops are subjected to a rigorous pre-market safety assessment. The safety of novel proteins and other products is established, and through compositional analysis and animal studies, the safety of any observed changes is evaluated. These studies provide evidence that the new product is as safe as, or safer than, comparable varieties. It must be asked, however, if this rigorous analysis is necessary, because unregulated crops produced by other breeding methods also undergo genetic changes and contain unintended effects. Golden Rice poses infinitesimally small, if any, risk to consumers whilst it has the potential to spare millions of lives each year. However, because it is a transgenic crop, it cannot be deployed without years of expensive pre-market safety review. Paradoxically, if Golden Rice had been produced by less precise conventional methods of breeding, it would already be in the hands of poor farmers. It is concluded that the hyper-precautionary regulatory process applied to transgenic crops works to the extreme disadvantage of the hungry and the poor.
Genetic modification involves the insertion of genes from other organisms (within or between species) into host cells to select for desirable qualities. Potential benefits of GM foods include increased nutritional value; reduced allergenicity; pest and disease-resistance; and enhanced processing value. Possible detrimental outcomes include producing foods with novel toxins, allergens or reduced nutritional value, and development of antibiotic resistance or herbicide-resistant weeds. Benefits to individuals or populations need to be weighed against adverse health and environmental risks, and may differ between developing and Westernised countries. Whether testing and monitoring should exceed requirements for conventional foods is under debate. While not necessarily scientifically justifiable, consumer concerns have resulted in Australian and New Zealand requirements to label foods containing GM-produced proteins. Dissatisfied consumer advocacy groups are calling for all foods involving GM technology to be labelled, irrelevant of whether the final product contains novel protein. Goals to improve the quantity, quality and safety of foods are laudable; however, the primary aim of the bio-food industry is financial gain. GM foods may be as safe as conventional foods but public distrust runs high. It is important that discussion is informed by science and that claims of both benefits and risks are evidence-based, to ensure that the process is driven neither by the vested interest of the bio-technical multinational companies on the one hand, nor ill-informed public fears on the other.

The US market for organic foods has grown from $3.5 billion in 1996 to $28.6 billion in 2010, according to the Organic Trade Association. Organic products are now sold in specialty stores and conventional supermarkets. Organic products contain numerous marketing claims and terms, only some of which are standardized and regulated. In terms of health advantages, organic diets have been convincingly demonstrated to expose consumers to fewer pesticides associated with human disease. Organic farming has been demonstrated to have less environmental impact than conventional approaches. However, current evidence does not support any meaningful nutritional benefits or deficits from eating organic compared with conventionally grown foods, and there are no well-powered human studies that directly demonstrate health benefits or disease protection as a result of consuming an organic diet. Studies also have not demonstrated any detrimental or disease-promoting effects from an organic diet. Although organic foods regularly command a significant price premium, well-designed farming studies demonstrate that costs can be competitive and yields comparable to those of conventional farming techniques. Pediatricians should incorporate this evidence when discussing the health and environmental impact of organic foods and organic farming while continuing to encourage all patients and their families to attain optimal nutrition and dietary variety consistent with the US Department of Agriculture's MyPlate recommendations. This clinical report reviews the health and environmental issues related to organic food production and consumption. It defines the term "organic," reviews organic food-labeling standards, describes organic and conventional farming practices, and explores the cost and environmental implications of organic production techniques. It examines the evidence available on nutritional quality and production contaminants in conventionally produced and organic foods. Finally, this

Anthropogenic climate change appears to be increasing the frequency, duration and intensity of extreme weather events. Such events have already had substantial impacts on socioeconomic development and population health. Climate change's most profound impacts are likely to be on food, health systems and water. This paper explores how climate change will affect food, human health and water in China. Projections indicate that the overall effects of climate change, land conversion and reduced water availability could reduce Chinese food production substantially - although uncertainty is inevitable in such projections. Climate change will probably have substantial impacts on water resources - e.g. changes in rainfall patterns and increases in the frequencies of droughts and floods in some areas of China. Such impacts would undoubtedly threaten population health and well-being in many communities. In the short-term, population health in China is likely to be adversely affected by increases in air temperatures and pollution. In the medium to long term, however, the indirect impacts of climate change - e.g. changes in the availability of food, shelter and water, decreased mental health and well-being and changes in the distribution and seasonality of infectious diseases - are likely to grow in importance. The potentially catastrophic consequences of climate change can only be avoided if all countries work together towards a substantial reduction in the emission of so-called greenhouse gases and a substantial increase in the global population's resilience to the risks of climate variability and change.

The US Food Security Scale (USFSS) measures household and child food insecurity (CFI) separately. Our goal was to determine whether CFI increases risks posed by household food insecurity (HFI) to child health and whether the Food Stamp Program (FSP) modifies these effects. From 1998 to 2004, 17,158 caregivers of children ages 36 mo were interviewed in six urban medical centers. Interviews included demographics, the USFSS, child health status, and hospitalization history. Ten percent reported HFI, 12% HFI and CFI (H&CFI). Compared with food-secure children, those with HFI had significantly greater adjusted odds of fair/poor health and being hospitalized since birth, and those with H&CFI had even greater adverse effects. Participation in the FSP modified the effects of FI on child health status and hospitalizations, reducing, but not eliminating, them. Children in FSP-participating households that were HFI had lower adjusted odds of fair/poor health [1.37 (95% CI, 1.06-1.77)] than children in similar non-FSP households [1.61 (95% CI, 1.31-1.98)]. Children in FSP-participating households that were H&CFI also had lower adjusted odds of fair/poor health [1.72 (95% CI, 1.34-2.21)] than in similar non-FSP households [2.14 (95% CI, 1.81-2.54)]. HFI is positively associated with fair/poor health and hospitalizations in young children. With H&CFI, odds of fair/poor health and hospitalizations are even greater. Participation in FSP reduces, but does not eliminate, effects of FI on fair/poor health.

Microalgae contain a variety of bioactive lipids with potential applications in aquaculture feed, biofuel, food and pharmaceutical industries. While microalgae-derived polyunsaturated fatty acid (PUFA) and their roles in promoting human health have been extensively studied, other lipid types from this resource, such as phytosterols, have been poorly explored. Phytosterols have been used as additives in many food products such as spread, dairy products and salad dressing. This review focuses on the recent advances in microalgae-derived phytosterols with functional bioactivities and their potential applications in functional food and pharmaceutical industries. It highlights the importance of microalgae-derived lipids other than PUFA for the development of an advanced microalgae industry.
One of the most widespread health problems in the Caribbean and Latin America is contaminated food and foodborne illness. The Pan American Health Organization (PAHO) has been a major force in activities to strengthen food protection. The program within the regional Program of Technical Cooperation is administered by the Veterinary Public Health program and under the guidance of the Pan American Institute for Food protection and Zoonoses in Buenos Aires, Argentina. A food action plan for 1986-90 was established at the 1986 Pan American Sanitary Conference, and extended to cover 1991-95. Program activities during the 1990s covered cholera, epidemiologic surveillance, street food vendors, shellfish poisoning, meat, national programs, information systems, air catering, food irradiation, and tourism. The action plan for 1991-95 promoted greater political support and cooperation within and between related sectors and institutions, management, and education. The aims were to organize national integrated programs, to strengthen laboratory services, to strengthen inspection services, to establish epidemiologic surveillance systems, and to promote food protection through community participation. Program activities included the initiatives of the Veterinary Public Health Program in 1991 to distribute literature on the transmission of cholera by foods. Studies were conducted in Bolivia, Colombia, and Peru on food contamination. Microbiologists received training on standard methods for detecting Vibrio cholerae in foods. A working group of experts from 10 countries examined the issues and produced a guide for investigating the incidence of foodborne disease. PAHO has contributed to the formation of an Inter-American Network for Epidemiologic Surveillance of Foodborne Diseases. PAHO has worked to improve hygienic practices among street food vendors. Seminars on paralytic shellfish poisoning were conducted in 1990; the outcome was a network working to strengthen national

Australia's food and health patterns are inextricably and increasingly linked with Asia. Indigenous Australians arrived in the continent via Asia and have linguistic connections with people who settled in south India; there was interaction and food trade between both South-East Asia and China and northern indigenous Australians over thousands of years. After European settlement in 1788, there have been several and increasing (apart from the period of the infamous White Australian Policy following the Colonial period and Independence, with Federation, in 1901) waves of Asian migration, notably during the gold rush (Chinese), the building of the overland Telegraph (Afghans), the Colombo Plan and Asian student education in Australia from the 1950s onwards (South-Eeast Asians), and with refugees (Vietnamese and mainland Chinese), and business (late twentieth century) and progressive family reunion. Each wave has injected additional food cultural elements and caused a measure of health change for migrants and host citizens. Of principal advantage to Australia has been the progressive diversification of the food supply and associated health protection. This has increased food security and sustainability. The process of Australian eating patterns becoming Asianized is evident through market garden development (and the introduction of new foods), fresh food markets and groceries, restaurants and the development of household cooking skills (often taught by student boarders). Most of the diversification has been with grain (rice), legumes (soy), greens, root vegetables, and various 'exotic fruits'. Food acculturation with migration is generally bi-directional. Thus, for Asians in Australia, there has been a decrease in energy expenditure (and a lower plane of energy throughput), an increase in food energy density (through increased fat and sugary drink intakes), and a decrease in certain health protective foods (lentils, soy, greens) and beverages (tea). This sets the stage

In this article we built formula database of health food containing Gardeniae Fructus with Traditional Chinese Medicine Inheritance Support System (V2.0). And on this basis, use data mining method such as association rules of the software, to analyze commonly used formula raw materials or materials combination of formula containing Gardeniae Fructus and raw material application having assisted function formula to protect chemical liver injury. The result shows that of the 71 health food formulas containing Gardeniae Fructus, most used materials are Gardeniae Fructus, Lycii Fructus, Angelica Sinensis Radix, Poria and so on. Commonly used materials combination mostly are Gardeniae Fructus and Lycii Fructus, Gardeniae Fructus and Angelica Sinensis Radix, Gardeniae Fructus and Poria, Gardeniae Fructus and Paeonia. There are nearly 18 healthcare functions of the health food containing Gardeniae Fructus, and most of these are assisted functions to protect chemical liver injury, and then immune modulating function. Of 23 formulas containing Gardeniae Fructus having assisted function formula to protect chemical liver injury, Gardeniae Fructus usually combined with traditional Chinese medicine which nourishs blood and liver such as Pueraria, Lycii Fructus, Hawthorn, Paeonia and Turnjujube. Analyzing formula raw materials application of health food containing Gardeniae Fructus contributes a lot to the further development and utilization.
The merits and demerits of food with health claims for the prevention of metabolic syndrome (MS) are reviewed. One major underlying cause of MS is obesity. Diet and lifestyle changes remain the cornerstones of therapy for obesity, but resulting weight loss is often small and long-term success is extremely uncommon and disappointing. Many anti-obesity drugs have been associated with unintended therapeutic outcomes. Currently, only one drug (mazindol) is approved in Japan for short-term treatment of individuals with a BMI over 35 kg/m(2). Treatment with orlistat with dietary modification, caffeine, or protein supplementation; consuming a low-fat diet; adherence to physical activity routines; prolonged contact with participants; problem-solving therapy; and the alternative treatment of acupressure are efficacious in reducing weight regain after weight loss treatment. Because obesity is highly stigmatized, any effective treatment should be made available to improve quality of life and self-image. Therefore, it is necessary to provide information to consumers through the media concerning 1) basic knowledge about health foods and laws concerning them, 2) scientifically based information on safety/effectiveness of health foods and food elements, and 3) reports on health disturbances associated with health foods around the world.

The marine ecosystem is still an untapped reservoir of biologically active compounds, which have considerable potential to supply food ingredients towards development of new functional foods. With the goal of increasing the availability and chemical diversity of functional marine ingredients, much research has been developed using biotechnological tools to discover and produce new compounds. This review summarizes the advances in biotechnological tools for production of functional ingredients, including enzymes, for the food industry. Tools involving biotechnological processes (bioreactors, fermentations, bioprocessing) and those involving genetic research designated as molecular biotechnology are discussed highlighting how they can be used in the controlled manipulation and utilization of marine organisms as sources of food ingredients, as well as discussing the most relevant shortcomings towards applications in new functional foods.

What food is produced, and how, can have a critical impact on human nutrition and the environment, which in turn are key drivers of healthy human reproduction and development. The US food production system yields a large volume of food that is relatively low in cost for consumers but is often high in calories and low in nutritional value. In this article we examine the evidence that intensive use of pesticides, chemical fertilizers, hormones, antibiotics, and fossil fuel in food production, as well as chemicals in food packaging, are potentially harmful to human reproductive and developmental health. We conclude that policies to advance a healthy food system are necessary to prevent adverse reproductive health effects and avoid associated health costs among current and future generations. These policies include changes to the Farm Bill and the Toxic Substances Control Act, and greater involvement by the health care sector in supporting and sourcing food from urban agriculture programs, farmers' markets, and local food outlets, as well as increasing understanding by clinicians of the links between reproductive health and industrialized food production.

Production of livestock accounts for 18% of anthropogenic greenhouse gas emissions. Although livestock products can alleviate malnutrition in poor countries, they are associated with diseases of affluence in wealthy countries. Red meat (pork, beef, sheep and goat), especially, is associated with higher rates of death due to cardiovascular disease and cancer. A policy of reducing consumption of red meat in wealthy countries and encouraging a limited consumption increase in poor countries would benefit the climate as well as human health.

Biodiversity increases the ability of ecosystems to provide multiple functions. Most studies report a positive relationship between species richness and the number of ecosystem functions. However, it is not known whether the number of functional groups is related to the structure of the underlying species interaction network. Here we present food web data from 115 salt marsh islands and show that network structure is associated with the number of functional groups present. Functional group diversity is heterogeneously distributed across spatial scales, with some islands hosting more functional groups than others. Functional groups form modules within the community so that food webs with more modular architectures have more functional group diversity. Further, in communities with different interaction types, modularity can be seen as the multifunctional equivalent of trophic complementarity. Collectively, these findings reveal spatial heterogeneity in the number of functional groups that emerges from patterns in the structure of the food web. PMID:26059871

Media advocacy is a well-established strategy for transmitting health messages to the public. This paper discusses a media advocacy intervention that raised issues about how the public interprets messages about the negative effects of poverty on population health. In conjunction with the publication of a manuscript illustrating how income-related food insecurity leads to disparities related to the consumption of a popular food product across Canada (namely, Kraft Dinner®), we launched a media intervention intended to appeal to radio, television, print and Internet journalists. All the media coverage conveyed our intended message that food insecurity is a serious population health problem, confirming that message framing, personal narratives and visual imagery are important in persuading media outlets to carry stories about poverty as a determinant of population health. Among politicians and members of the public (through on-line discussions), the coverage provoked on-message as well as off-message reactions. Population health researchers and health promotion practitioners should anticipate mixed reactions to media advocacy interventions, particularly in light of new Internet technologies. Opposition to media stories regarding the socio-economic determinants of population health can provide new insights into how we might overcome challenges in translating evidence into preventive interventions.

Changes in our understanding of diet and health drive changes in the way foods are processed. Conversely, what is available on the shelf will have an impact on the choices consumers make, thereby affecting their health. Historical examples of industrial manipulation of the diet include fortification and enrichment of cereal grains with vitamins; increased production of unsaturated vegetable oils and margarine as substitutions for hydrogenated fat, lard, and butter; lowered cholesterol content foods; reduced sugar content foods; lower sodium foods; decreased portion sizes or caloric density in prepackaged foods for use in weight loss or maintenance; and increased calcium levels to prevent osteoporosis. However, degenerative diseases such as cancer, atherosclerosis, bone disease, arthritis, and dementia will continue to be prevalent in the future. Whether or not the food systems available on the shelf can influence all of these disease states is not clear; however, studies have indicated that nutritional factors do contribute to the development of some of these diseases. Patterns in food consumption have changed and will continue to change as recommendations such as decreased consumption of saturated fats, salt, and cholesterol continue to be made. Increased ingestion of fish and/or fish oil is one recommendation that has been suggested because of the effect of omega-3 fatty acids on platelet aggregability and circulating levels of lipids. Wildly speculating from preliminary studies, fish oil has also been recommended for disease states including arthritis, cancer, and diseases of the immune system.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2401259

Sleep is a vital segment of life, however, the mechanisms of diet promoting sleep are unclear and are the focus of research. Insomnia is a general sleep disorder and functional foods are known to play a key role in the prevention of insomnia. A number of studies have demonstrated that major insomnia risk factors in human being are less functional foods in dietary. There are higher functional components in functional foods promoting sleep, including tryptophan, GABA, calcium, potassium, melatonin, pyridoxine, L-ornithine and hexadecanoic acid; but wake-promoting neurochemical factors include serotonin, noradrenalin, acetylcholine, histamine, orexin and so on. The factors promoting sleep in human being are the functional foods include barley grass powder, whole grains, maca, panax, Lingzhi, asparagus powder, lettuce, cherry, kiwifruits, walnut, schisandra wine, and milk; Barley grass powder with higher GABA and calcium, as well as potassium is the most ideal functional food promoting sleep, however, the sleep duration for modern humans is associated with food structure of ancient humans. In this review, we put forward possible mechanisms of functional components in foods promoting sleep. Although there is clear relevance between sleep and diet, their molecular mechanisms need to be studied further. PMID:26005400

The Food Health Quality Research Program (Investigación de la Calidad Sanitaria de los Alimentos [ICSA]) of the Public Health Agency of Barcelona (Agencia de Salud Pública de Barcelona [ASPB]) was initiated in 1984 to carry out surveillance of certain chemical and microbiological parameters related to the sanitary and safety of foods sold in the city. The present article analyzes the importance of health surveillance and provides details of the uses of the ICSA program. The main aim of this program is to evaluate whether marketed foods comply with the absence and/or established tolerance levels of specific parameters. Nevertheless, the program is able to incorporate or suppress parameters or foods that pose emerging dangers or interests not represented in current legislation. Besides, the program not only obtains a view of the parameters studied at a specific time period in each report, but also accumulates data over time, allowing risk assessment, calculation of dietary intake of contaminants, analysis of tendencies, and evaluation of the effectiveness of regulations to reduce contaminants. The program can also help in the planning of food control programs. The information obtained is disseminated nationally and internationally and is included in dossiers of contaminants issued by national and European health agencies. This demonstrates that a locally-developed surveillance system can have a wider scope and broader objectives and can provide useful information for managers, administrations, economic operators and consumers.

The US food system functions within a complex nexus of social, political, economic, cultural, and ecological factors. Among them are many dynamic pressures such as population growth, urbanization, socioeconomic inequities, climate disruption, and the increasing demand for resource-intensive foods that place immense strains on public health and the environment. This review focuses on the role that policy plays in defining the food system, particularly with regard to agriculture. It further examines the challenges of making the food supply safe, nutritious, and sustainable, while respecting the rights of all people to have access to adequate food and to attain the highest standard of health. We conclude that the present US food system is largely unhealthy, inequitable, environmentally damaging, and insufficiently resilient to endure the impacts of climate change, resource depletion, and population increases, and is therefore unsustainable. Thus, it is imperative that the US embraces policy reforms to transform the food system into one that supports public health and reflects the principles of human rights and agroecology for the benefit of current and future generations.

The aim of this review is to describe the factors contributing to diminished food intake, resulting in nutritional deficiencies and associated health conditions in older adults and proposes food innovation strategies to mitigate these. Research has provided convincing evidence of a link between healthy eating patterns and healthy aging. There is a need to target new food product development (NPD) with functional health benefits specifically designed to address the particular food-related needs of older consumers. When developing foods for older adults, consideration should be given to the increased requirements for specific macro- and micronutrients, especially protein, calcium, vitamin D, and vitamin B. Changes in chemosensory acuity, chewing difficulties, and reduced or poor swallowing ability should also be considered. To compensate for the diminished appetite and reduced intake, foods should be energy dense, nutritionally adequate, and, most importantly, palatable, when targeting this cohort. This paper describes the potential of new food product development to facilitate dietary modification and address health deficiencies in older adults.

Chronic diseases related to unbalanced and unhealthy eating habits have definitely become one of the major issues of modern age, not only in western countries but also in those ones where rapid economic growth has increased global prosperity levels. In order to avoid medical systems to collapse under excessive costs, International and Public Organizations strongly support health policies that aim to make people shift towards wholesome dietary patterns, also encouraging the use of food-labels to choose healthier products. To evaluate the consumers' knowledge and perception about food-labels a brief questionnaire was developed and shared on Facebook between January-March 2016. Most of the participants were young adults with higher education. They declared to do their shopping at least once a week, reading the food-labels quite often. Despite owing limited knowledge in basic nutrition principles and food-labelling they were generally able to recognize healthier products looking over their nutritional fact tables. Anyway, on average, what they care the most about the products they purchase is the global quality level rather than the nutritional values. In order to induce the whole population to use food label as an effective self-protection tool, more efforts should be done to improve their knowledge on nutrition fundamentals and basics about food labelling, because that would make them able to take safer and more conscious choices as regards their own health.

Serotonin has been implicated in promoting self-control, regulation of hunger and physiological homeostasis, and regulation of caloric intake. However, it remains unclear whether the effects of serotonin on caloric intake reflect purely homeostatic mechanisms, or whether serotonin also modulates cognitive processes involved in dietary decision making. We investigated the effects of an acute dose of the serotonin reuptake inhibitor citalopram on choices between food items that differed along taste and health attributes, compared with placebo and the noradrenaline reuptake inhibitor atomoxetine. Twenty-seven participants attended three sessions and received single doses of atomoxetine, citalopram, and placebo in a double-blind randomised cross-over design. Relative to placebo, citalopram increased choices of more healthy foods over less healthy foods. Citalopram also increased the emphasis on health considerations in decisions. Atomoxetine did not affect decision making relative to placebo. The results support the hypothesis that serotonin may influence food choice by enhancing a focus on long-term goals. The findings are relevant for understanding decisions about food consumption and also for treating health conditions such as eating disorders and obesity.

Since the initial passage in 1906 of the first Pure Food and Drug Act and the Meat Inspection Act, public health, as measured by mortality trends, has greatly improved. These acts have been amended several times, and other laws dealing with safety of foods and drinks have been enacted. Food- and beverage-transmitted infectious diseases that were so devastating after the Civil War have been controlled. Nutritional deficiencies such as pellagra are almost nonexistent. Mass episodes of poisoning of food by chemical contaminants that have plagued some other countries have not occurred in the United States. Other factors such as refrigeration and improved transportation have helped, but it is probable that food safety regulatory activities have contributed to the saving of the 1.8 million Americans who would die each year if the public health advances since 1900 had not been made. Effective use of information was a key factor in the improvement in public health. Now, as then, effective information systems are needed. PMID:3097743

OBJECTIVES 1) quantify the association between food avoidance and modification due to oral health problems; 2) quantify the relationship between these nutritional self-management strategies and dietary quality; and 3) determine foods associated with these self-management strategies. DESIGN Cross-sectional SETTING Rural North Carolina PARTICIPANTS Six hundred thirty-five community-dwelling adults aged 60 years and older. MEASUREMENTS Demographic and food frequency data and oral health assessments were obtained during home visits. Avoidance (none, 1–2 foods, 3–14 foods) and modification (0–3 foods, 4–5 foods) was assessed for foods representing oral health challenges. Food frequency data were converted into Healthy Eating Index-2005 (HEI-2005) scores. Linear regression models tested the significance of associations between HEI-2005 measures and food avoidance and modification. RESULTS Thirty-five percent of the sample avoided 3–14 foods and 28% modified 4–5 foods. After adjusting for age, sex, ethnicity, poverty, education, and tooth loss, the total HEI-2005 score was lower (P<0.001) for persons avoiding more foods and higher for persons modifying more foods (P<0.001). Those avoiding 3–14 foods consumed more saturated fat and energy from solid fat and added sugar and lower intake of non-hydrogenated fats than those avoiding <3 foods. Those who modified 4–5 foods consumed less saturated fat and solid fat and added sugar but more total grains than those modifying <4 foods. CONCLUSION Food avoidance and modification due to oral health problems are associated with significant differences in dietary quality. Approaches to minimize food avoidance and promote food modification by persons having eating difficulties due to oral health conditions are needed. PMID:20533966

A probiotic dairy product was developed on the basis of a traditional dish called mutandabota to enable resource-poor populations in southern Africa to benefit from a functional food. Mutandabota is widely consumed in rural southern Africa, making it an ideal food matrix to carry probiotics. First, a process to produce probiotic mutandabota was designed. Raw cow milk was boiled and subsequently cooled to ambient temperature (25°C). Next, dry pulp from the fruit of the baobab tree (Adansonia digitata L.) was added to the milk at a concentration of 4% (wt/vol). This mixture was inoculated with the probiotic Lactobacillus rhamnosus yoba and left to ferment for 24h, while the growth of the bacterial culture was monitored. Final ingredients were then added to produce probiotic mutandabota that had 14% (wt/vol) baobab fruit pulp and 7% (wt/vol) sugar in cow milk. The pH of probiotic mutandabota was pH 3.5, which ensures that the product is microbiologically safe. The viable plate count of L. rhamnosus yoba increased from 5.8 ± 0.3 log cfu/mL at the point of inoculation to 8.8 ± 0.4 log cfu/mL at the moment of consumption, thereby meeting the criterion to have a viable count of the probiotic bacterium in excess of 6 log cfu/mL of a product. Baobab fruit pulp at 4% promoted growth of L. rhamnosus yoba with a maximal specific growth rate (μmax) of 0.6 ± 0.2/h at 30°C. The developed technology, though specific for this particular product, has potential to be applied for the delivery of probiotics through a variety of indigenous foods in different regions of the world. Upon consumption, probiotic mutandabota is expected to improve the population's intestinal health, which is especially relevant for vulnerable target groups such as children and elderly people.

Besides being important in the fermentation of foods and beverages, yeasts have shown numerous beneficial effects on human health. Among these, probiotic effects are the most well known health effects including prevention and treatment of intestinal diseases and immunomodulatory effects. Other beneficial functions of yeasts are improvement of bioavailability of minerals through the hydrolysis of phytate, folate biofortification and detoxification of mycotoxins due to surface binding to the yeast cell wall.

The United Nations declared 2016 as the International Year of Pulses (grain legumes) under the banner 'nutritious seeds for a sustainable future'. A second green revolution is required to ensure food and nutritional security in the face of global climate change. Grain legumes provide an unparalleled solution to this problem because of their inherent capacity for symbiotic atmospheric nitrogen fixation, which provides economically sustainable advantages for farming. In addition, a legume-rich diet has health benefits for humans and livestock alike. However, grain legumes form only a minor part of most current human diets, and legume crops are greatly under-used. Food security and soil fertility could be significantly improved by greater grain legume usage and increased improvement of a range of grain legumes. The current lack of coordinated focus on grain legumes has compromised human health, nutritional security and sustainable food production.

Food provides energy and nutrients, but its acquisition requires energy expenditure. In post-hunter-gatherer societies, extra-somatic energy has greatly expanded and intensified the catching, gathering, and production of food. Modern relations between energy, food, and health are very complex, raising serious, high-level policy challenges. Together with persistent widespread under-nutrition, over-nutrition (and sedentarism) is causing obesity and associated serious health consequences. Worldwide, agricultural activity, especially livestock production, accounts for about a fifth of total greenhouse-gas emissions, thus contributing to climate change and its adverse health consequences, including the threat to food yields in many regions. Particular policy attention should be paid to the health risks posed by the rapid worldwide growth in meat consumption, both by exacerbating climate change and by directly contributing to certain diseases. To prevent increased greenhouse-gas emissions from this production sector, both the average worldwide consumption level of animal products and the intensity of emissions from livestock production must be reduced. An international contraction and convergence strategy offers a feasible route to such a goal. The current global average meat consumption is 100 g per person per day, with about a ten-fold variation between high-consuming and low-consuming populations. 90 g per day is proposed as a working global target, shared more evenly, with not more than 50 g per day coming from red meat from ruminants (ie, cattle, sheep, goats, and other digastric grazers).

The food-based dietary guidelines in the Scandinavian countries that recommend an intake of minimum 75 g whole grain per 10 MJ (2,388 kcal) per day are mainly derived from prospective cohort studies where quantitative but little qualitative details are available on whole grain products. The objective of the current paper is to clarify possible differences in nutritional and health effects of the types of whole grain grown and consumed in the Scandinavian countries. A further objective is to substantiate how processing may influence the nutritional value and potential health effects of different whole grains and whole grain foods. The most commonly consumed whole grain cereals in the Scandinavian countries are wheat, rye, and oats with a considerable inter-country variation in the consumption patterns and with barley constituting only a minor role. The chemical composition of these different whole grains and thus the whole grain products consumed vary considerably with regard to the content of macro- and micronutrients and bioactive components. A considerable amount of scientific substantiation shows that processing methods of the whole grains are important for the physiological and health effects of the final whole grain products. Future research should consider the specific properties of each cereal and its processing methods to further identify the uniqueness and health potentials of whole grain products. This would enable the authorities to provide more specific food-based dietary guidelines in relation to whole grain to the benefit of both the food industry and the consumer. PMID:23411562

Pacific Island countries (PICs) are experiencing an epidemic of obesity and consequent chronic diseases. Despite investment in the development of National Plans of Action for Nutrition (NPANs) and interventions to promote healthy eating and physical activity, nutritional status appears to show little improvement. This paper presents a synthesis of the findings from two research papers that were prepared for a 2003 food safety and quality meeting in Nadi, Fiji. The findings indicate that although lifestyle behaviours might be the immediate cause of dietary imbalances, greater attention should focus on omnipresent influences of globalization as a critical element of the nutrition transition in the Pacific. In particular, those aspects of globalization mediated through the World Trade Organization (WTO) Agreements that are placing pressures on food security and fostering increased dependence on imported food of poor nutritional quality. Rapid, significant and sustainable improvements in public health in PICs require interventions that can tackle these underlying contributors to ill health. There are opportunities to explore the use of food regulatory approaches to influence the composition, availability and accessibility of food products. Within the context of the WTO Agreements the legitimacy of food regulatory approaches will depend upon the case to demonstrate the relationship between the intervention and the protection of food security and public health nutrition. The challenges in realising these opportunities are: 1) to have the capacity to construct a case, 2) meet the technical and financial demands to administer and enforce regulatory approaches, and 3) to take advantage of opportunities available and to be able to fully participate in the international policy-making process.

This paper examines the ecological association of dietary food intake with mental health outcomes on the group level across countries. Published data from the World Mental Health Survey were used to compare lifetime prevalence of four categories of mental health disorders (anxiety disorders, mood disorders, impulse control disorders, and substance use disorders) with a country's fish/seafood and sugar/sweetener supply quantity using the Spearman rank correlation. Data were compared for 17 countries across the world. Sugar and sweetener supply quantity was significantly and positively associated with anxiety disorders (rho=0.75, p=0.001), mood disorders (rho=0.75, p=0.001), impulse control disorders (rho=0.78, p=0.001), and substance use disorders (rho=0.68, p=0.007). Fish and seafood supply quantity had no significant association with any mental health disorders. Mental health disorders represent a significant health problem around the world. Public health measures aimed at improving the quality and availability of a nation's food supply could have a significant positive impact on mental health. Further randomized studies are needed to further validate the study findings.

The 2008 food crisis may have increased household food insecurity and caused distress among impoverished populations in low-income countries. Policy researchers have attempted to quantify the impact that a sharp rise in food prices might have on population wellbeing by asking what proportion of households would drop below conventional poverty lines given a set increase in prices. Our understanding of the impact of food crises can be extended by conducting micro-level ethnographic studies. This study examined self-reported household food insecurity (FI) and common mental disorders (CMD) among 110 community health AIDS care volunteers living in Addis Ababa, Ethiopia during the height of the 2008 food crisis. We used generalized estimating equations that account for associations between responses given by the same participants over 3 survey rounds during 2008, to model the longitudinal response profiles of FI, CMD symptoms, and socio-behavioral and micro-economic covariates. To help explain the patterns observed in the response profiles and regression results, we examine qualitative data that contextualize the cognition and reporting behavior of AIDS care volunteers, as well as potential observation biases inherent in longitudinal, community-based research. Our data show that food insecurity is highly prevalent, that is it associated with household economic factors, and that it is linked to mental health. Surprisingly, the volunteers in this urban sample did not report increasingly severe FI or CMD during the peak of the 2008 food crisis. This is a counter-intuitive result that would not be predicted in analyses of population-level data such as those used in econometrics simulations. But when these results are linked to real people in specific urban ecologies, they can improve our understanding of the psychosocial consequences of food price shocks.
Recent advances in emerging food-processing technologies, such as high hydrostatic pressure or high-intensity electric field pulses, allow targeted and sophisticated modification and preservation of foods. We are beginning to understand the mechanisms involved in pressure inactivation of bacterial spores and have been collecting considerable amounts of kinetic data regarding inactivation mechanisms of enzymes and vegetative microorganisms. We are also gaining more insight into the permeabilization of plant membranes and related biosynthetic responses, making progress in food structure engineering and food modification for function, and have been initiating process developments for gentle processing of delicate biomaterials based on pressure-assisted phase transitions of water.
Veterinarians play a key role in food security. The health of millions of people, stimulation of national economies, development of sustainable livestock production related to this food source, and the different agricultural production systems that compose value chains, and access to more profitable international markets all depend on their efficient and transparent work. Shifting nutritional patterns globally, along with expected population growth, and the increase in marketable food commodity routes and volumes, forecast that demand for animal source food will steadily intensify over the coming decades. To successfully address these challenges, the veterinary profession should establish more practical and up-to-date conceptual and methodological frameworks for academic and professional profiles, focusing the profession on the different public health subject areas, in undergraduate and graduate courses. Furthermore, interdisciplinary alliances should also be developed--such as the "One Health" approach proposed by the United Nations Food and Agriculture Organization (FAO), the World Organization for Animal Health (OIE), and the World Health Organization (WHO)--to establish frameworks for joint work and public policies more in line with the domestic conditions of Latin American countries, using a collaborative, sustainable, and comprehensive approach to animal health, food security, and public health policy.

The fields of immunology, microbiology, and nutrition converge in an astonishing way. Dietary ingredients have a profound effect on the composition of the gut microflora, which in turn regulates the physiology of metazoans. As such, nutritional components of the diet are of critical importance not only for meeting the nutrient requirements of the host, but also for the microbiome. During their coevolution, bacterial microbiota has established multiple mechanisms to influence the eukaryotic host, generally in a beneficial fashion. The microbiome encrypts a variety of metabolic functions that complements the physiology of their hosts. Over a century ago Eli Metchnikoff proposed the revolutionary idea to consume viable bacteria to promote health by modulating the intestinal microflora. The idea is more applicable now than ever, since bacterial antimicrobial resistance has become a serious worldwide problem both in medical and agricultural fields. The impending ban of antibiotics in animal feed due to the current concern over the spread of antibiotic resistance genes makes a compelling case for the development of alternative prophylactics. Nutritional approaches to counteract the debilitating effects of stress and infection may provide producers with useful alternatives to antibiotics. Improving the disease resistance of animals grown without antibiotics will benefit the animals' health, welfare, and production efficiency, and is also a key strategy in the effort to improve the microbiological safe status of animal-derived food products (e.g. by poultry, rabbits, ruminants, or pigs). This review presents some of the alternatives currently used in food-producing animals to influence their health in relation to human health.

From the current state-of-the-art, it is clear that nanotechnology applications are expected to bring a range of benefits to the food sector aiming at providing better quality and conservation. In the meantime, a growing number of studies indicate that the exposure to certain engineered nanomaterials (ENMs) has a potential to lead to health complications and that there is a need for further investigations in order to unravel the biological outcomes of nanofood consumption. In the current review, we summarize the existing data on the (potential) use of ENMs in the food industry, information on the toxicity profiles of the commonly applied ENMs, such as metal (oxide) nanoparticles (NPs), address the potential food safety implications and health hazards connected with the consumption of nanofood. A number of health complications connected with the human exposure to ENMs are discussed, demonstrating that there is a real basis for the arisen concern not only connected with the gut health, but also with the potency to lead to systemic toxicity. The toxicological nature of hazard, exposure levels and risk to consumers from nanotechnology-derived food are on the earliest stage of investigation and this review also highlights the major gaps that need further research and regulation.

Government food and beverage policies can play an important role in promoting public health. Few people would question this assumption. Difficult questions can arise, however, when policymakers, public health officials, citizens, and businesses deliberate about food and beverage policies, because competing values may be at stake, such as public health, individual autonomy, personal responsibility, economic prosperity, and fairness. An ethically justified policy strikes a reasonable among competing values by meeting the following criteria: (1) the policy serves important social goal(s); (2) the policy is likely to be effective at achieving those goal(s); (3) less burdensome options are not likely to be effective at achieving the goals; (4) the policy is fair.

In the Asian region, indigenous fermented foods are important in daily life. In many of these foods, yeasts are predominant and functional during the fermentation. The diversity of foods in which yeasts predominate ranges from leavened bread-like products such as nan and idli, to alcoholic beverages such as rice and palm wines, and condiments such as papads and soy sauce. Although several products are obtained by natural fermentation, the use of traditional starter cultures is widespread. This minireview focuses on the diversity and functionality of yeasts in these products, and on opportunities for research and development.

Globalization has greatly accelerated the numbers and variety of food and beverage products available worldwide. The exchange among greater numbers of countries, manufacturers, and products in the United States and worldwide has necessitated enhanced quality measures for nutritional products for larger populations increasingly reliant on functionality. These functional foods, those that provide benefit beyond basic nutrition, are increasingly being used for their potential to alleviate food insufficiency while enhancing quality and longevity of life. In the United States alone, a steady import increase of greater than 15% per year or 24 million shipments, over 70% products of which are food related, is regulated under the Food and Drug Administration (FDA). This unparalleled growth has resulted in the need for faster, cheaper, and better safety and efficacy screening methods in the form of harmonized guidelines and recommendations for product standardization. In an effort to meet this need, the in vitro toxicology testing market has similarly grown with an anticipatory 15% increase between 2010 and 2015 of US$1.3 to US$2.7 billion. Although traditionally occupying a small fraction of the market behind pharmaceuticals and cosmetic/household products, the scope of functional food testing, including additives/supplements, ingredients, residues, contact/processing, and contaminants, is potentially expansive. Similarly, as functional food testing has progressed, so has the need to identify potential adverse factors that threaten the safety and quality of these products.

Abstract Anthropogenic climate change appears to be increasing the frequency, duration and intensity of extreme weather events. Such events have already had substantial impacts on socioeconomic development and population health. Climate change’s most profound impacts are likely to be on food, health systems and water. This paper explores how climate change will affect food, human health and water in China. Projections indicate that the overall effects of climate change, land conversion and reduced water availability could reduce Chinese food production substantially – although uncertainty is inevitable in such projections. Climate change will probably have substantial impacts on water resources – e.g. changes in rainfall patterns and increases in the frequencies of droughts and floods in some areas of China. Such impacts would undoubtedly threaten population health and well-being in many communities. In the short-term, population health in China is likely to be adversely affected by increases in air temperatures and pollution. In the medium to long term, however, the indirect impacts of climate change – e.g. changes in the availability of food, shelter and water, decreased mental health and well-being and changes in the distribution and seasonality of infectious diseases – are likely to grow in importance. The potentially catastrophic consequences of climate change can only be avoided if all countries work together towards a substantial reduction in the emission of so-called greenhouse gases and a substantial increase in the global population’s resilience to the risks of climate variability and change.

Results of several major studies on food systems for space missions beginning with Apollo 12 through Apollo-Soyuz and investigations of the application of irradiation to food for manned space flight are reported. The study of flight food systems involved the application of radurization (pasteurizing levels) doses of gamma irradiation to flour and bread supplied by Pepperidge Farms in advance of the missions. All flights from Apollo 12 through 17 carried irradiated fresh bread. On Apollo 17, cooperation with Natick Laboratories permitted the introduction of a ham sandwich using irradiated bread and irradiated sterile ham. Investigations centered on irradiated bread were conducted during the course of these missions. Studies were applied to the concept of improving fresh bread from the point of view of mold inhibition. The studies considered how irradiation could best be applied at what levels and on a variety of bread types. Throughout the studies of the application of gamma irradiation the emphasis was placed upon using low levels of irradiation in the pasteurizing or radurizing doses--under a Megarad. The primary goal was to determine if a public health benefit could be demonstrated using radurization along with food preservation and food quality improvements. The public health benefit would be parallel to that of pasteurization of milk as a concept. Publications are included providing the details of these observations, one dealing with the flour characteristics and the other dealing with the influence on fresh bread types. These demonstrate the major findings noted during the period of the studies examining bread.

Functional foods are one of the most interesting areas of research and innovation in the food industry. A functional food or functional ingredient is considered to be any food or food component that provides health benefits beyond basic nutrition. Recently, consumers have shown interest in natural bioactive compounds as functional ingredients in the diet owing to their various beneficial effects for health. Water-soluble fibers and nondigestible oligosaccharides and polysaccharides can be defined as functional food ingredients. Fructooligosaccharides (FOS) and inulin are resistant to direct metabolism by the host and reach the caecocolon, where they are used by selected groups of beneficial bacteria. Furthermore, they are able to improve physical and structural properties of food, such as hydration, oil-holding capacity, viscosity, texture, sensory characteristics, and shelf-life. This article reviews major innovative analytical developments to screen and identify FOS, inulins, and the most employed nonstarch carbohydrates added or naturally present in functional food formulations. High-performance anion-exchange chromatography with pulsed electrochemical detection (HPAEC-PED) is one of the most employed analytical techniques for the characterization of those molecules. Mass spectrometry is also of great help, in particularly matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS), which is able to provide extensive information regarding the molecular weight and length profiles of oligosaccharides and polysaccharides. Moreover, MALDI-TOF-MS in combination with HPAEC-PED has been shown to be of great value for the complementary information it can provide. Some other techniques, such as NMR spectroscopy, are also discussed, with relevant examples of recent applications. A number of articles have appeared in the literature in recent years regarding the analysis of inulin, FOS, and other carbohydrates of interest in the field and

The development of the sports food market and industrial involvement have led to numerous nutritional studies to define the type of nutrients that are most suited to support energy metabolism, fluid balance and muscle function. The key question in many of these studies was: 'Does the product lead to a significant product/consumer benefit that can be used as a claim on the package?' New methods and techniques have been developed, partly with sponsorship of the food industry, with the goal of measuring the effects of specific nutrients and supplements on athletic performance and metabolism. In line with this development, a wide variety of supplements and sports foods/drinks labelled with various performance or health benefit statements have been launched on the sports nutrition market. Although a variety of products have been tested clinically, there are also many products on the market with benefit claims that cannot be supported by sound nutritional and sports physiological science. The current short review highlights some of the methods and biomarkers that are used to substantiate product/consumer benefit claims for foods and drinks that are marketed as functional foods for athletes.

Do food ecosystems feed gut ecosystems? And if so… fuel the immune system? Recent developments in metagenomics have provided researchers tools to open the "black box" of microbiome science. These novel technologies have enabled the establishment of correlations between dysbiotic microbial communities and many diseases. The complex interaction of the commensal microbiota with the immune system is a topic of substantial interest due to its relevance to health. The human gastrointestinal tract is composed of an immense number of resident and transient microorganisms. Both may play a direct and vital role in the maintenance of human health and well-being. An understanding of the interactions and mechanisms through which commensal and food-derived microbes shape host immunity and metabolism may yield new insights into the pathogenesis of many immune-mediated diseases. Consequently, by manipulating the contribution of food microbiota to the functionality of the gut ecosystem, there is great hope for development of new prophylactic and therapeutic interventions. This paper presents some insights and comments on the possible impact of exogenous fermented food microbes on the gut homeostasis. We shed light on the similar features shared by both fermented food microbes and probiotics. In particular, the key role of microbial strains as part of food ecosystems for health and diseases is discussed through the prism of fermented dairy products and gut inflammation.

From many reports it is clear that diabetes will be one of the major diseases in the coming years. As a result there is a rapidly increasing interest in searching new medicines, or even better searching prophylactic methods. Based on a large number of chemical and pharmacological research work, numerous bioactive compounds have been found in functional herbal food ingredients for diabetes. The present paper reviews functional herbal food ingredients with regards to their anti-diabetic active principles and pharmacological test results, which are commonly used in Asian culinary system and medical system and have demonstrated clinical or/and experimental anti-diabetic effectiveness. Our idea of reviewing this article is to give more attention to these functional food ingredients as targets medicinal foods in order to prevent or slow down the development of type 2 diabetes mellitus.

The global biodiversity crisis concerns not only unprecedented loss of species within communities, but also related consequences for ecosystem function. Community ecology focuses on patterns of species richness and community composition, whereas ecosystem ecology focuses on fluxes of energy and materials. Food webs provide a quantitative framework to combine these approaches and unify the study of biodiversity and ecosystem function. We summarise the progression of food-web ecology and the challenges in using the food-web approach. We identify five areas of research where these advances can continue, and be applied to global challenges. Finally, we describe what data are needed in the next generation of food-web studies to reconcile the structure and function of biodiversity.

This review addresses epidemiological, public health, and social policy implications of categorizing young children and their adult female caregivers in the United States as food secure when they live in households with "marginal food security," as indicated by the U.S. Household Food Security Survey Module. Existing literature shows that households in the US with marginal food security are more like food-insecure households than food-secure households. Similarities include socio-demographic characteristics, psychosocial profiles, and patterns of disease and health risk. Building on existing knowledge, we present new research on associations of marginal food security with health and developmental risks in young children (<48 mo) and health in their female caregivers. Marginal food security is positively associated with adverse health outcomes compared with food security, but the strength of the associations is weaker than that for food insecurity as usually defined in the US. Nonoverlapping CIs, when comparing odds of marginally food-secure children's fair/poor health and developmental risk and caregivers' depressive symptoms and fair/poor health with those in food-secure and -insecure families, indicate associations of marginal food security significantly and distinctly intermediate between those of food security and food insecurity. Evidence from reviewed research and the new research presented indicates that households with marginal food security should not be classified as food secure, as is the current practice, but should be reported in a separate discrete category. These findings highlight the potential underestimation of the prevalence of adverse health outcomes associated with exposure to lack of enough food for an active, healthy life in the US and indicate an even greater need for preventive action and policies to limit and reduce exposure among children and mothers.

Intensive animal rearing, manipulation of crop production and food processing have altered the qualitative and quantitative balance of nutrients of foods consumed by Western society. This change, to which the physiology and biochemistry of man may not be presently adapted to, is thought to be responsible for the chronic diseases that are rampant in the Industrialised Western Countries. Agriculture production and food processing practices, dietary habits and lifestyle of the West is being fostered without any appraisal of the health implications by most developing countries. Consequently, a rising trend in the incidences of obesity, diabetes, high blood pressure, cardiovascular diseases, dental decay and appendicitis is apparent. Mediterranean countries are adopting the agriculture and food practices of northern Europe as the result of the harmonisation of European food and agriculture policy. It is predicted that the low incidence of morbidity and mortality from coronary heart disease, stroke, diabetes and breast and colon cancer of the Mediterranean countries would rise to the high northern European level in the foreseeable future. Most of these chronic diseases are lifestyle related and are preventable. This can be realised by tackling the root problem which is food production and processing practices and not by dispensing designer drugs or opening more hospital beds.

A large body of clinical evidence suggests that the consumption of 3 g or more per d of β-glucan from oats or barley, as part of a diet low in saturated fat and cholesterol, may reduce the risk of CHD. The unique chemical and physical properties of oats and physiological responses to oat consumption contribute to their demonstrated health benefits; other health attributes are still under evaluation. Many of these benefits, such as those associated with a reduced risk of CVD, are codified in health claims by several regulatory agencies, such as the Food and Drug Administration in the USA and the European Food Safety Authority in Europe. Despite these oat-health relationships, an apparent decline in agricultural production, the presence of an array of plant pathogens, and dynamics of climatic conditions may preclude the availability and subsequent consumption of this commodity worldwide. Therefore, it is incumbent on scientists from multiple disciplines to advance research in a spectrum of arenas, including physico-chemical properties of oats, the impact of oats on an array of non-communicable diseases and human microbiome, agricultural practices and environments, and processing technologies that contribute to global food policies.

Cardiovascular disease (CVD) is now the leading cause of death globally and is a growing health concern. Dietary factors are important in the pathogenesis of CVD and may to a large degree determine CVD risk, but have been less extensively investigated. Functional foods are those that are thought to have physiological benefits and/or reduce the risk of chronic disease beyond their basic nutritional functions. The food industry has started to market products labelled as “functional foods.” Although many review articles have focused on individual dietary variables as determinants of CVD that can be modified to reduce the risk of CVD, the aim of this current paper was to examine the impact of functional foods in relation to the development and progression of CVD. Epidemiologic studies have demonstrated the association between certain dietary patterns and cardiovascular health. Research into the cardio-protective potential of their dietary components might support the development of functional foods and nutraceuticals. This paper will also compare the effect of individual bioactive dietary compounds with the effect of some dietary patterns in terms of their cardiovascular protection. PMID:22570771

Infectious diseases transmitted by food have become a major public health concern in recent years. In the USA alone, there are an estimated 6-33 million cases each year. The list of responsible agents continues to grow. In the past 20 years some dozen new pathogens that are primarily food-borne have been identified. Fruits and vegetables, often from the global food market, have been added to the traditional vehicles of food-borne illness; that is, undercooked meat, poultry, seafood, or unpasteurized milk. Such products are minimally processed and have fewer barriers to microbial growth such as salt, sugar or preservatives. The evolution of the epidemiology of food-borne illness requires a rethinking of traditional, though still valid, solutions for their prevention. Among various strategies to prevent food-borne pathogens, use of dietary phytochemicals is promising. The major obstacle in the use of dietary phytochemical is the consistency of phytochemicals in different foods due to their natural genetic variation. We have developed a novel tissue-culture-based selection strategy to isolate elite phenolic phytochemical-producing clonal lines of species belonging to the family Lamiaceae. Among several species we have targeted elite clonal lines of thyme (Thymus vulgaris) and oregano (Origanum vulgare) against Escherichia coli and Clostridium perfrigens in fresh and processed meats. We are also evaluating high phenolic profile-containing clonal lines of basil (Ocimum basilicum) to inhibit gastric ulcer-causing Helicobacter pylori. Other elite lines of the members of the family Lamiaceae, rosemary (Rosmarinus officinalis) and salvia (Salvia officinalis) also hold promise against a wide range of food pathogens such as Salmonella species in poultry products and Vibrio species in seafood.
Obesity is a major health problem in the developed and developing world. Many "functional" foods and ingredients are advocated for their effects on body composition but few have consistent scientific support for their efficacy. However, an increasing amount of mechanistic and clinical evidence is building for green tea. The tea plant is naturally rich in a group of antioxidants known as catechins. Unlike black tea, green tea production involves little processing and fermentation and therefore, green tea brews are rich in catechins. Green tea has been suggested to have a number of potential health benefits in areas such as cardiovascular disease, cancer prevention, glucose homeostasis and dental health. Although there is some promising evidence in all of these areas, more data from human intervention trials are needed. A lot of attention has lately been focused on the beneficial effects of green tea on body composition and particularly visceral fat, which has been shown to have a strong link with different components of the metabolic syndrome such as cardiovascular disease and type 2 diabetes. Most, but not all, of the positive results come from a number Asian studies, in which overweight subjects (men and women) consumed green tea for approximately 12 weeks. Finally, green tea may also have measurable acute effects on energy metabolism and fat oxidation and in particular during physical activity, as evidenced by other studies specifically looking at these endpoints. Small cumulative effects on energy metabolism could also be responsible for the longer-tem effects of green tea on body composition, and these long-term effects may also be most apparent in the context of moderate physical activity. However, more research is needed to further clarify the exact mechanisms of action and to extrapolate these findings to non-Asian populations.

It is beneficial for both the public health community and the food industry to meet nutritional needs of elderly consumers through product formats that they want. The heterogeneity of the elderly market poses a challenge, however, and calls for market segmentation. Although many researchers have proposed ways to segment the elderly consumer population, the elderly food market has received surprisingly little attention in this respect. Therefore, the present paper reviewed eight potential segmentation bases on their appropriateness in the context of functional foods aimed at the elderly: cognitive age, life course, time perspective, demographics, general food beliefs, food choice motives, product attributes and benefits sought, and past purchase. Each of the segmentation bases had strengths as well as weaknesses regarding seven evaluation criteria. Given that both product design and communication are useful tools to increase the appeal of functional foods, we argue that elderly consumers in this market may best be segmented using a preference-based segmentation base that is predictive of behaviour (for example, attributes and benefits sought), combined with a characteristics-based segmentation base that describes consumer characteristics (for example, demographics). In the end, the effectiveness of (combinations of) segmentation bases for elderly consumers in the functional food market remains an empirical matter. We hope that the present review stimulates further empirical research that substantiates the ideas presented in this paper.
With the gluten-free food market worth almost $1.6 bn in 2011, there is every reason for renewed interest in ancient grains. This resurgent interest is expressed in re-discovering ancient varieties as functional foods. In particular, people affected by celiac disease have to avoid all gluten in their diet and several ancient grains may offer an important alternative. PMID:26151025

Chronic diseases related to unbalanced and unhealthy eating habits have definitely become one of the major issues of modern age, not only in western countries but also in those ones where rapid economic growth has increased global prosperity levels. In order to avoid medical systems to collapse under excessive costs, International and Public Organizations strongly support health policies that aim to make people shift towards wholesome dietary patterns, also encouraging the use of food-labels to choose healthier products. To evaluate the consumers’ knowledge and perception about food-labels a brief questionnaire was developed and shared on Facebook between January-March 2016. Most of the participants were young adults with higher education. They declared to do their shopping at least once a week, reading the food-labels quite often. Despite owing limited knowledge in basic nutrition principles and food-labelling they were generally able to recognize healthier products looking over their nutritional fact tables. Anyway, on average, what they care the most about the products they purchase is the global quality level rather than the nutritional values. In order to induce the whole population to use food label as an effective self-protection tool, more efforts should be done to improve their knowledge on nutrition fundamentals and basics about food labelling, because that would make them able to take safer and more conscious choices as regards their own health. Significance for public health Food label represents the identity card of food products: it reports composition, ingredients and their relative amounts, it informs about quality, origin, processing and preservation. This information gives the consumer the opportunity to consciously choose what to purchase. The label could concretely help us in protecting and improving our health, if our choices are supported by some basic knowledge of wholesome nutrition, based on a balanced and varied diet. In a wider

Recent work by epidemiologists and microbiologists has uncovered several hitherto unrecognized food-borne bacterial pathogens of public health significance. One of these, Listeria monocytogenes, has attracted considerable attention because of two major cheese-related outbreaks of listeriosis that were characterized by cases of meningitis, abortion, and perinatal septicemia. Thus far, L. monocytogenes has been responsible for well over 300 reported cases of food-borne listeriosis, including about 100 deaths, and has cost the dairy industry alone more than 66 million dollars as a result of product recalls. The ability of L. monocytogenes to grow at refrigeration temperatures, coupled with appearance of the pathogen in raw and processed meats, as well as poultry, vegetables, and seafood, makes this bacterium a serious threat to susceptible consumers and to the entire food industry. Yersinia enterocolitica, another psychrotrophic food-borne pathogen of recent concern, was linked to several outbreaks of yersiniosis associated with consumption of both raw and pasteurized milk, as well as contaminated water. Food-borne infections involving Y. enterocolitica typically result in enterocolitis, which may be mistaken for acute appendicitis. Unfortunately, inadvertent removal of healthy appendixes from victims of food-borne yersiniosis is all too common. Although known for many years, Campylobacter jejuni has only recently been recognized as a food-borne pathogen and a leading cause of gastroenteritis in the United States. Notable outbreaks of campylobacteriosis linked to consumption of raw milk, cake icing, eggs, poultry, and beef have underscored the need for thorough cooking and proper handling of raw products.(ABSTRACT TRUNCATED AT 250 WORDS)

Feeding experiments comparing organically and conventionally produced food are performed to assess the overall impact on the animals' health as a model for the effects experienced by the human consumers. These experiments are based on systems research and characterized by their focus on production methods, whole food testing and procedures in accordance with the terms of organic farming. A short review of such experiments shows that the majority of these tests revealed effects of the organically produced feed on health parameters such as reproductive performance and immune responses. Systems research is not just about simple cause-effect chains, but rather about the pluralism of interactions in biological networks; therefore, the interpretation of the outcome of whole food experiments is difficult. Furthermore, the test diets of organic and conventional origin can be constituted in different ways, compensating for or maintaining existing differences in nutrient and energy contents. The science-based results suggest positive influences from organic feeds, but there is still a need for confirmation in animals and, finally, in humans. For this purpose animal feeding trials with feed from different production systems should be conducted, with the aims to define health indicators and to establish biomarkers as a basis for future dietary intervention studies in humans.
Twenty-first-century food policy will have to address a new set of fundamentals. Some are relatively new such as climate change and peak oil, and some merely new versions of very old ones such as water, population, land pressures, labor, and urbanisation. Policy-makers now need radically to alter the policy mix inherited from the last major policy reconfiguration in the mid-20th century. Then the demon was supply, and poor health was mainly due to underconsumption and poverty. The policy solution was to raise output and reduce prices. Today the challenge is more complex, a coexistence of over-, under-, and malconsumption alongside continuing gross inequalities within and between nations. The article proposes that a new paradigm is emerging, termed here ecological public health, which sees human and planetary health as linked and food as a key connection point. The article outlines aspects of what this entails, stressing the need for food policy to address not just supply but governance and consumer cultural challenges too. Seven priorities are proposed for policy-makers. PMID:23144673

ABSTRACT Polysaccharides derived from plant foods are major components of the human diet, with limited contributions of related components from fungal and algal sources. In particular, starch and other storage carbohydrates are the major sources of energy in all diets, while cell wall polysaccharides are the major components of dietary fiber. We review the role of these components in the human diet, including their structure and distribution, their modification during food processing and effects on functional properties, their behavior in the gastrointestinal tract, and their contribution to healthy diets.

Functional food for prevention of chronic diseases is one of this century's key global challenges. Cancer is not only the first or second leading cause of death in China and other countries across the world, but also has diet as one of the most important modifiable risk factors. Major dietary factors now known to promote cancer development are polished grain foods and low intake of fresh vegetables, with general importance for an unhealthy lifestyle and obesity. The strategies of cancer prevention in human being are increased consumption of functional foods like whole grains (brown rice, barley, and buckwheat) and by-products, as well some vegetables (bitter melon, garlic, onions, broccoli, and cabbage) and mushrooms (boletes and Tricholoma matsutake). In addition some beverages (green tea and coffee) may be protective. Southwest China (especially Yunnan Province) is a geographical area where functional crop production is closely related to the origins of human evolution with implications for anticancer influence.

There is a need to understand the role of fat, protein and carbohydrate in human health, and also how foods containing and/or structured using these macronutrients can be designed so that they can have a positive impact on health. This may include a reduction in fat, salt or sugar, the protection and targeted release of micronutrients or active ingredients from/to particular parts of the digestive system, improvement of gastrointestinal health or satiety enhancing properties. Such foods can be designed with various macro- and microstructures that will impact on macronutrient release and delivery. These include simple and double emulsions, the use of Pickering particles and shells, nanoparticles, liposomes, gelled networks, fluid gels and gel particles, foams, self-assembled structures, and encapsulated systems. In order to design foods that deliver these benefits understanding of how these structures behave in the gastrointestinal tract is also required, which should involve utilising both in vitro and in vivo studies. This review aims to draw together research in these areas, by focusing on the current state of the art, but also exciting possibilities for future research and food development.

Ayurveda, a traditional system of medicine that originated over three millennia ago in the South Asian region, offers extensive insights about food and health based on certain unique conceptual as well as theoretical positions. Health is defined as a state of equilibrium with one's self (svasthya) but which is inextricably linked to the environment. Ayurvedic principles, such as the tridosa (three humors) theory, provide the relationship between the microcosm and the macrocosm that can be applied in day-to-day practice. Classical Ayurveda texts cover an array of themes on food ranging from diversity of natural sources, their properties in relation to seasons and places and to their specific function both in physiological and pathological states. The epistemic perspective on health and nutrition in Ayurveda is very different from that of biomedicine and modern nutrition. However, contemporary knowledge is reinventing and advancing several of these concepts in an era of systems biology, personalized medicine, and the broader context of a more holistic transition in sciences in general. Trans-disciplinary research could be important not only for pushing the boundaries of food and health sciences but also for providing practical solutions for contemporary health conditions. This article briefly reviews the parallels in Ayurveda and biomedicine and draws attention to the need for a deeper engagement with traditional knowledge systems, such as Ayurveda. It points out that recreation of the methodologies that enabled the holistic view point about health in Ayurveda may unravel some of the complex connections with Nature.

Each individual is unique, with genetic factors that interact with a particular environment. Therefore, the daily energy requirements should be calculated individually and have to consider the several factors which influence them: basal metabolic rate, diet-induced thermogenesis, physical activity, specific diseases, among other factors. Food provides macronutrients: carbohydrates, proteins and lipids, as well as micronutrients: vitamins, minerals and oligoelements, which should be eaten daily in the recommended amounts during the life cycle, e.g. pregnancy, childhood, adolescence, adulthood and aging. Health professionals can use the "Roda dos Alimentos Portuguesa" to teach and guide the population on how to eat, whether they are healthy or ill individuals, in order to meet their nutritional needs. Through this tool it is possible for everyone to understand and to practice a diet that is: 1) complete (eating foods from all groups), 2) balanced (to respect the proportions of each food group, adjusting the recommended portions/amounts for each individual), and 3) diversified (to choose different foods within each group). Some studies show that food marketing and advertising influence the consumers' choices since childhood. There is already some Regulation in this field, especially about nutrition and health claims. However, a permanent supervision of food marketing is necessary, to ensure compliance with the European Regulation from EFSA. It is crucial to teach and to encourage people to carefully read the food labels before purchasing. Health professionals should also be aware, academically and professionally, about the basics principles of Food and Health Promotion. The unique and essential role of the Professionals of Nutrition needs to be valued and recognized, and these professionals have to be integrated in sufficient number, in the multidisciplinary teams of the National Health Service, whether in Hospitals or Health Care Centers for the ambulatory population

Pectin, a complex polysaccharide rich in galacturonic acid, has been identified as a critical structural component of plant cell walls. The functionality of this intricate macromolecule in fruit- and vegetable-based-derived products and ingredients is strongly determined by the nanostructure of its most abundant polymer, homogalacturonan. During food processing, pectic homogalacturonan is susceptible to various enzymatic as well as nonenzymatic conversion reactions modifying its structural and, hence, its functional properties. Consequently, a profound understanding of the various process-structure-function relations of pectin aids food scientists to tailor the functional properties of plant-based derived products and ingredients. This review describes the current knowledge on process-structure-function relations of pectin in foods with special focus on pectin's functionality with regard to textural attributes of solid plant-based foods and rheological properties of particulated fruit- and vegetable-derived products. In this context, both pectin research performed via traditional, ex situ physicochemical analyses of fractionated walls and isolated polymers and pectin investigation through in situ pectin localization are considered.

In recent years, the impact of soy foods and supplements upon human health has become increasingly controversial among the general public. No one has conducted a broad evaluation of the scientific evidence supporting or refuting popular perceptions of the health effects of soy consumption. In this article, the authors have conducted a comprehensive assessment of the literature surrounding the health effects of soy consumption that are of greatest interest. This review has focused on 5 health benefits- relief of menopausal symptoms and prevention of heart disease, breast cancer, prostate cancer, and osteoporosis, and 5 health risks-increased risk of breast cancer, male hormonal and fertility problems, hypothyroidism, antinutrient content, and harmful processing by-products. Systematic reviews of human trials, prospective human trials, observational human studies, animal models, in vitro studies, and laboratory analyses of soy components were included for review. This literature review revealed that soy foods and isoflavones may provide relief from menopausal symptoms and protect against breast cancer and heart disease. Soy does not appear to offer protection against osteoporosis. The evidence on male fertility and reproductive hormones was conflicting; some studies demonstrated a deleterious impact caused by soy consumption and others showed no effect. Soy supplementation also appears to affect thyroid function in an inconsistent manner, as studies have shown both increases and decreases in the same parameters of thyroid activity. Soaking, fermentation, and heating may reduce problematic antinutrients contained in soy. The authors found that consuming moderate amounts of traditionally prepared and minimally processed soy foods may offer modest health benefits while minimizing potential for adverse health effects. However, additional studies are necessary to elucidate the variable thyroid response to soy supplementation, and more rigorous studies are required to

Polyunsaturated omega-3 fatty acids (PUFAs), a functional component present in vegetable oils, are generally recognized as being beneficial to health. Omega-3 PUFAs are rich in double bonds and unsaturated in nature; this attribute makes them highly susceptible to lipid oxidation and unfit for incorporation into long shelf life foods. The microencapsulation of oils in a polymeric matrix (mainly polysaccharides) offers the possibility of controlled release of the lipophilic functional ingredient and can be useful for the supplementation of foods with PUFAs. The present paper provides a literature review of different vegetable sources of omega-3 fatty acids, the functional effects of omega-3 fatty acids, different microencapsulation methods that can possibly be used for the encapsulation of oils, the properties of vegetable oil microcapsules, the effect of encapsulation on oxidation stability and fatty acid composition of vegetable oils, and the incorporation of long-chain omega-3 polyunsaturated fatty acids in foods.

Optofluidics is a rapidly advancing field that utilizes the integration of optics and microfluidics to provide a number of novel functionalities in microsystems. In this review, we discuss how this approach can potentially be applied to address some of the greatest challenges facing both the developing and developed world, including healthcare, food shortages, malnutrition, water purification, and energy. While medical diagnostics has received most of the attention to date, here we show that some other areas can also potentially benefit from optofluidic technology. Whenever possible we briefly describe how microsystems are currently used to address these problems and then explain why and how optofluidics can provide better solutions. The focus of the article is on the applications of optofluidic techniques in low-resource settings, but we also emphasize that some of these techniques, such as those related to food production, food safety assessment, nutrition monitoring, and energy production, could be very useful in well-developed areas as well.

Most food products are highly perishable as they constitute a rich nutrient source for microbial development. Among the microorganisms contaminating food, some present metabolic activities leading to spoilage. In addition to hygienic rules to reduce contamination, various treatments are applied during production and storage to avoid the growth of unwanted microbes. The nature and appearance of spoilage therefore depend on the physiological state of spoilers and on their ability to resist the processing/storage conditions and flourish on the food matrix. Spoilage also relies on the interactions between the microorganisms composing the ecosystems encountered in food. The recent rapid increase in publicly available bacterial genome sequences, as well as the access to high-throughput methods, should lead to a better understanding of spoiler behavior and to the possibility of decreasing food spoilage. This review lists the main bacterial species identified as food spoilers, their ability to develop during storage and/or processing, and the functions potentially involved in spoilage. We have also compiled an inventory of the available genome sequences of species encompassing spoilage strains. Combining in silico analysis of genome sequences with experimental data is proposed in order to understand and thus control the bacterial spoilage of food better.

Previous scholarship on novel foods, including functional foods, has suggested that they are difficult to categorise for both regulators and users. It is argued that they blur the boundary between ‘food' and ‘drug' and that uncertainties about the products create ‘experimental' or ‘restless' approaches to consumption. We investigate these uncertainties drawing on data about the use of functional foods containing phytosterols, which are licensed for sale in the EU for people wishing to reduce their cholesterol. We start from an interest in the products as material objects and their incorporation into everyday practices. We consider the scripts encoded in the physical form of the products through their regulation, production and packaging and find that these scripts shape but do not determine their use. The domestication of phytosterols involves bundling the products together with other objects (pills, supplements, foodstuffs). Considering their incorporation into different systems of objects offers new understandings of the products as foods or drugs. In their accounts of their practices, consumers appear to be relatively untroubled by uncertainties about the character of the products. We conclude that attending to materials and practices offers a productive way to open up and interrogate the idea of categorical uncertainties surrounding new food products. PMID:26157471

Bioactive peptides (BAPs), derived through enzymatic hydrolysis of food proteins, have demonstrated potential for application as health-promoting agents against numerous human health and disease conditions, including cardiovascular disease, inflammation, and cancer. The feasibility of pharmacological application of these peptides depends on absorption and bioavailability in intact forms in target tissues, which in turn depends on structure of the peptides. Therefore, production and processing of peptides based on important structure-function parameters can lead to the production of potent peptides. This article reviews the literature on BAPs with emphasis on strategic production and processing methods as well as antihypertensive, anticancer, anticalmodulin, hypocholesterolemic, and multifunctional properties of the food protein-derived peptides. It is recommended that future research efforts on BAP should be directed toward elucidation of their in vivo molecular mechanisms of action, safety at various doses, and pharmacological activity in maintaining homeostasis during aberrant health conditions in human subjects.

The scale of the obesity epidemic creates a pressing consumer need as well as an enormous business opportunity for successful development and marketing of food products with added benefits for weight control. A number of proposed functional food ingredients have been shown to act post-absorptively to influence substrate utilization or thermogenesis. Characteristics and supporting data on conjugated linoleic acid, diglycerides, medium-chain triglycerides, green tea, ephedrine, caffeine, capsaicin and calcium, are reviewed here, giving examples of how these could act to alter energy expenditure or appetite control. Consideration is also given to other factors, in addition to efficacy, which must be satisfied to get such ingredients into foods. We conclude that, for each of the safe, putatively metabolically active agents, there remain gaps in clinical evidence or knowledge of mechanisms, which need to be addressed in order to specify the dietary conditions and food product compositions where these ingredients could be of most benefit for weight control.

Background Food insecurity, uncertainty about the ability to acquire adequate food, is associated with cardiometabolic disease in pregnant women. Whether food insecurity interventions improve cardiometabolic health is unknown. Methods We conducted a retrospective analysis of women who visited the obstetrics clinic in a community health center from 2013 through 2015. Patients could be referred to the Food for Families (Food for Families) program, which connects food insecure women to food resources. We hypothesized that participation in Food for Families would be associated with better blood pressure and blood glucose trends during pregnancy. We used a propensity score–matched design to reduce bias from differential entry into Food for Families. Results Eleven percent of women who visited the obstetrics clinic were referred to Food for Families. In propensity score–matched analyses, we found no difference in baseline systolic blood pressure (SBP) between those who were referred and enrolled in Food for Families (113.5 mm Hg), those who were referred and did not enroll in Food for Families (113.9 mm Hg), and those who were not referred to Food for Families (114 mm Hg) (P = .79). However, during pregnancy, women who were referred to and enrolled in Food for Families had a better SBP trend (0.2015 mm Hg/wk lower, P = .006). SBP trends did not differ between women who were referred and did not enroll in Food for Families and those who were not referred. We observed no differences in blood glucose trends between groups (P = .40). Conclusions Food for Families participation was associated with better blood pressure trends in pregnant women but no differences in blood glucose trends. Food insecurity reduction programs may improve cardiovascular health for vulnerable pregnant women, and this topic deserves further study incorporating randomized program entry. PMID:27809418

The viable but nonculturable (VBNC) state is a unique survival strategy of many bacteria in the environment in response to adverse environmental conditions. VBNC bacteria cannot be cultured on routine microbiological media, but they remain viable and retain virulence. The VBNC bacteria can be resuscitated when provided with appropriate conditions. A good number of bacteria including many human pathogens have been reported to enter the VBNC state. Though there have been disputes on the existence of VBNC in the past, extensive molecular studies have resolved most of them, and VBNC has been accepted as a distinct survival state. VBNC pathogenic bacteria are considered a threat to public health and food safety due to their nondetectability through conventional food and water testing methods. A number of disease outbreaks have been reported where VBNC bacteria have been implicated as the causative agent. Further molecular and combinatorial research is needed to tackle the threat posed by VBNC bacteria with regard to public health and food safety. PMID:24191231

The present study was to investigate the effects of diltiazem, a ghrelin receptor agonist, on food intake and gastrointestinal functions in rats. Rats were intragastrically administered with diltiazem solution (daily 16 mg/kg, 30 mg/kg or 80 mg/kg, 30 d), and the rats with saline as control. To detect the effects of diltiazem on food intake and body weight, the average daily food intake and body weight were recorded, and the serum metabolic hormones of plasma growth hormone (GH) and neuropeptide Y (NPY) were tested by radioimmunoassay. By means of the spectrophotometer and the modified Mett's method, the effects of diltiazem on rat's gastrointestinal function and pepsin activity were tested, respectively. In addition, the gastric juice's acidity of rats was detected by titration and the secretion amount was calculated. The results showed that the food intake and body weight were maximally promoted by diltiazem at the dose of 30 mg/kg daily (30 d). The average daily food intake and body weight were significantly increased, and the serum concentrations of GH and NPY were also remarkably increased in diltiazem-treated groups compared with those in control group. The results also showed that the gastric emptying rate, gastric acid secretion and the activity of pepsin were significantly increased in diltiazem-treated group compared with those in control group. These results suggest that diltiazem induces enhancement of eating, in the same time, it can also stimulate the gastrointestinal function and regulate growth of rat.

Food labelling on food packaging has the potential to have both positive and negative effects on diets. Monitoring different aspects of food labelling would help to identify priority policy options to help people make healthier food choices. A taxonomy of the elements of health-related food labelling is proposed. A systematic review of studies that assessed the nature and extent of health-related food labelling has been conducted to identify approaches to monitoring food labelling. A step-wise approach has been developed for independently assessing the nature and extent of health-related food labelling in different countries and over time. Procedures for sampling the food supply, and collecting and analysing data are proposed, as well as quantifiable measurement indicators and benchmarks for health-related food labelling.

Health conditions are sometimes included in entertainment media comedies as a context for and as a source of humor. Food allergies are a typical case in point: They are potentially life-threatening yet may be used in humorous contexts. We conducted a content analysis of food allergies in entertainment media and tested the effects of humorous portrayals from an exemplar entertainment program. The content analysis confirmed that when food allergies were portrayed in television and the movies, it was most frequently in a humorous context and often contained inaccurate information. A follow-up experiment showed viewing a humorous portrayal of food allergies had an indirect negative effect on related health policy support via decreased perceived seriousness of food allergies. Inclusion of an educational video eliminated this effect on reduced policy support, with cognitive dissonance as a mediator. Findings support the hypothesis that portraying a health condition in a humorous context may reduce perceptions of seriousness and willingness to support public health policies to address risks associated with the condition, supporting and extending prior research findings.

Health and sustainability guidelines for institutional food service are directed at improving dietary intake and increasing the ecological benefits of the food system. The development and implementation of institutional food service guidelines, such as the Health and Human Services (HHS) and General Services Administration (GSA) Health and Sustainability Guidelines for Federal Concessions and Vending Operations (HHS/GSA Guidelines), have the potential to improve the health and sustainability of the food system. Institutional guidelines assist staff, managers, and vendors in aligning the food environment at food service venues with healthier and more sustainable choices and practices. Guideline specifics and their effective implementation depend on the size, culture, nature, and management structure of an institution and the individuals affected. They may be applied anywhere food is sold, served, or consumed. Changing institutional food service practice requires comprehensive analysis, engagement, and education of all relevant stakeholders including institutional management, members of the food supply chain, and customers. Current examples of food service guidelines presented here are the HHS and GSA Health and Sustainability Guidelines for Federal Concessions and Vending Operations, which translate evidence-based recommendations on health and sustainability into institutional food service practices and are currently being implemented at the federal level. Developing and implementing guidelines has the potential to improve long-term population health outcomes while simultaneously benefitting the food system. Nutritionists, public health practitioners, and researchers should consider working with institutions to develop, implement, and evaluate food service guidelines for health and sustainability.

This study is part of the research undertaken in the EU funded project CLYMBOL ("Role of health-related CLaims and sYMBOLs in consumer behaviour"). The first phase of this project consisted of mapping the prevalence of symbolic and non-symbolic nutrition and health-related claims (NHC) on foods and non-alcoholic beverages in five European countries. Pre-packaged foods and drinks were sampled based on a standardized sampling protocol, using store lists or a store floor plan. Data collection took place across five countries, in three types of stores. A total of 2034 foods and drinks were sampled and packaging information was analyzed. At least one claim was identified for 26% (95% CI (24.0%-27.9%)) of all foods and drinks sampled. Six percent of these claims were symbolic. The majority of the claims were nutrition claims (64%), followed by health claims (29%) and health-related ingredient claims (6%). The most common health claims were nutrient and other function claims (47% of all claims), followed by disease risk reduction claims (5%). Eight percent of the health claims were children's development and health claims but these were only observed on less than 1% (0.4%-1.1%) of the foods. The category of foods for specific dietary use had the highest proportion of NHC (70% of foods carried a claim). The prevalence of symbolic and non-symbolic NHC varies across European countries and between different food categories. This study provides baseline data for policy makers and the food industry to monitor and evaluate the use of claims on food packaging.

Fast growing food processing industry in most countries across the world, generates huge quantity of by-products, including pomace, hull, husk, pods, peel, shells, seeds, stems, stalks, bran, washings, pulp refuse, press cakes, etc., which have less use and create considerable environmental pollution. With growing interest in health promoting functional foods, the demand of natural bioactives has increased and exploration for new sources is on the way. Many of the food processing industrial by-products are rich sources of dietary, functional, and novel fibers. These by-products can be directly (or after certain modifications for isolation or purification of fiber) used for the manufacture of various foods, i.e. bread, buns, cake, pasta, noodles, biscuit, ice creams, yogurts, cheese, beverages, milk shakes, instant breakfasts, ice tea, juices, sports drinks, wine, powdered drink, fermented milk products, meat products and meat analogues, synthetic meat, etc. A comprehensive literature survey has been carried on this topic to give an overview in the field dietary fiber from food by-products. In this article, the developments in the definition of fiber, fiber classification, potential sources of dietary fibers in food processing by-products, their uses, functional properties, caloric content, energy values and the labelling regulations have been discussed.

The presence of nitrates and nitrites in food is associated with an increased risk of gastrointestinal cancer and, in infants, methemoglobinemia. Despite the physiologic roles for nitrate and nitrite in vascular and immune function, consideration of food sources of nitrates and nitrites as healthful dietary components has received little attention. Approximately 80% of dietary nitrates are derived from vegetable consumption; sources of nitrites include vegetables, fruit, and processed meats. Nitrites are produced endogenously through the oxidation of nitric oxide and through a reduction of nitrate by commensal bacteria in the mouth and gastrointestinal tract. As such, the dietary provision of nitrates and nitrites from vegetables and fruit may contribute to the blood pressure-lowering effects of the Dietary Approaches to Stop Hypertension (DASH) diet. We quantified nitrate and nitrite concentrations by HPLC in a convenience sample of foods. Incorporating these values into 2 hypothetical dietary patterns that emphasize high-nitrate or low-nitrate vegetable and fruit choices based on the DASH diet, we found that nitrate concentrations in these 2 patterns vary from 174 to 1222 mg. The hypothetical high-nitrate DASH diet pattern exceeds the World Health Organization's Acceptable Daily Intake for nitrate by 550% for a 60-kg adult. These data call into question the rationale for recommendations to limit nitrate and nitrite consumption from plant foods; a comprehensive reevaluation of the health effects of food sources of nitrates and nitrites is appropriate. The strength of the evidence linking the consumption of nitrate- and nitrite-containing plant foods to beneficial health effects supports the consideration of these compounds as nutrients.

The advent of multiple global crises, especially those of climate change, economics, energy, water, food and health evident in 2008, is of considerable moment to those who are suffering their consequences and for those with responsibility and interest in the systems affected. A coalition of parties in the Asia Pacific Region who work in the food and health systems met in August, 2009 in Taiwan and instigated a Food in Health Security (FIHS) Network which might join with other like-minded networks in and beyond the region. Sustainable health has many dimensions, among which food and nutrition is often neglected; there is a wide spectrum of nutritionally-related disorders. Malnutrition remains the global concern for agricultural research and development scientists and linkage with the health sector is key to progress. The disconnect between agricultural and health sectors negatively impacts consumer nutrition and health. Ethical and equity affect food and health systems. Food and health security is attainable only when the underlying social inequities are addressed; it is an ethical issue as reflected in the UN Universal declaration of Human Rights which includes the right to food for health and well-being. Food and health security are part of the larger security agenda and merit corresponding attention. Policy recommendations with immediacy are greater investment in combined food and health research; an Asia Pacific security agenda which emphasizes planetary, human, health and food security as relevant to traditional defence security; and community and household security measures which include maternal literacy, communication technology and entrepreneurial opportunity.

Arsenic is a toxic metalloid of global concern. It usually originates geogenically but can be intensified by human activities such as applications of pesticides and wood preservatives, mining and smelting operations, and coal combustion. Arsenic-contaminated food is a widespread problem worldwide. Data derived from population-based studies, clinical case series, and case reports relating to ingestion of inorganic arsenic in drinking water, medications, or contaminated food or beverages show the capacity of arsenate and arsenite to adversely affect multiple organ systems. Chronic arsenic poisoning can cause serious health effects including cancers, melanosis (hyperpigmentation or dark spots, and hypopigmentation or white spots), hyperkeratosis (hardened skin), restrictive lung disease, peripheral vascular disease (blackfoot disease), gangrene, diabetes mellitus, hypertension, and ischemic heart disease.

We have been studying the evaluation of food, nutrition and functional substances, in the selected organic materials for useful life-support systems in closed bio-ecosystems for space agriculture on Mars in the future. We have already proposed several species as food materials; cyanobacterium, Nostoc sp. HK-01 and the Japanese cherry tree. Nostoc sp. HK-01 is a terrestrial cyanobacterium which has high tolerances to several space environments. In addition to its high tolerances to serious environments, HK-01 has a high protein content. Total protein per 100 g of the dried colony of Nostoc sp. HK-01 was approximately 50 g. Woody plant materials also have several properties which can be utilized in our habitation environment and as food. We have already found abilities to produce important functional substances for humans in the selected trees. Here, we show the extended results of our experiments.

Functional food products promote claims such as 'freedom from hunger' and 'feel fuller for longer'. A legislative framework has been established by the European Food Safety Authority to evaluate the validity of such claims: a claim must be substantiated by scientific evidence and should be clearly understood by consumers. Since consumed foods influence appetite by means of a system of physiological satiety signals, functional foods could in principle act by increasing the potency and/or duration of these signals. Importantly, what constitutes a useful action: a reduction in hunger, an increase in fullness, a change in food intake at a meal, an adjustment in daily energy balance or a reduction in body weight? Any claim should not go beyond the scientific evidence of an effect, and methods exist to scientifically evaluate claims. The wording of a claim is, therefore, critical. The difference between a proof of concept and a guarantee of success is an important point that needs to be conveyed to the consumer.
Whey is a byproduct of cheese making; whey proteins are globular proteins which can be modified and polymerized to add functional benefits, these benefits can be both nutritional and structural in foods. Modified proteins can be used in non-foods, being of particular interest in polymer films and coatings. Food packaging materials, including plastics, can linings, interior coatings of paper containers, and beverage cap sealing materials, are generally made of synthetic petroleum based compounds. These synthetic materials may pose a potential human health risk due to presence of certain chemicals such as Bisphenol A (BPA). They also add to environmental pollution, being difficult to degrade. Protein-based materials do not have the same issues as synthetics and so can be used as alternatives in many packaging types. As proteins are generally hydrophilic they must be modified structurally and their performance enhanced by the addition of waterproofing agents. Polymerization of whey proteins results in a network, adding both strength and flexibility. The most interesting of the food-safe waterproofing agents are the (large aspect ratio) nanoclays. Nanoclays are relatively inexpensive, widely available and have low environmental impact. The clay surface can be modified to make it organophilic and so compatible with organic polymers. The objective of this study is the use of polymerized whey protein (PWP), with reinforcing nanoclays, to produce flexible surface coatings which limit the transfer of contents while maintaining food safety. Four smectite and kaolin type clays, one treated and three natural were assessed for strengthening qualities and the potential waterproofing and plasticizing benefits of other additives were also analyzed. The nutritional benefits of whey proteins can also be used to enhance the protein content of various foodstuffs. Drinkable yogurt is a popular beverage in the US and other countries and is considered a functional food, especially when

The human enteric microbiome represents a veritable organ relied upon by the host for a range of metabolic and homeostatic functions. Through the production of metabolites such as short chain fatty acids (SCFA), folate, vitamins B and K, lactic acid, bacteriocins, peroxides and exopolysaccharides, the bacteria of the gut microbiome provide nutritional components for colonocytes, liver and muscle cells, competitively exclude potential pathogenic organisms and modulate the hosts immune system. Due to the extensive variation in structure, size and composition, microbial exopolysaccharides represent a useful set of versatile natural ingredients for the food industrial sector, both in terms of their rheological properties and in many cases, their associated health benefits. The exopolysaccharide-producing bacteria that fall within the 35 Lactobacillus and five Bifidobacterium species which have achieved qualified presumption of safety (QPS) and generally recognised as safe (GRAS) status are of particular interest, as their inclusion in food products can avoid considerable scrutiny. In addition, additives commonly utilised by the food industry are becoming unattractive to the consumer, due to the demand for a more 'natural' and 'clean labelled' diet. In situ production of exopolysaccharides by food-grade cultures in many cases confers similar rheological and sensory properties in fermented dairy products, as traditional additives, such as hydrocolloids, collagen and alginate. This review will focus on microbial synthesis of exopolysaccharides, the human health benefits of dietary exopolysaccharides and the technofunctional applications of exopolysaccharide-synthesising microbes in the food industry.
Cardiovascular diseases (CVD) are the leading cause of death globally (World Health Organisation, 2011). Many of the risk factors for CVD are modifiable, including overweight and obesity. Numerous strategies have been proposed to fight CVD, with a special focus being placed on dietary interventions for weight management. The literature suggests that two nutrients, fiber and protein, may play significant roles in weight control and hence cardiovascular health. Increasing both protein and fiber in the diet can be difficult because popular low-carbohydrate and high-protein diets tend to have considerably low-fiber intakes (Slavin, 2005). One approach to obtain both is to develop functional foods using unique ingredients. Lupin flour is a novel food ingredient derived from the endosperm of lupin. It contains 40-45% protein, 25-30% fiber, and negligible sugar and starch (Petterson and Crosbie, 1990). Research conducted to date reveals that lupin-enriched foods, which are naturally high in protein and fiber, may have a significant effect on CVD risk factors. This review explores whether there is a role for fiber-, protein-, and lupin-enriched foods in improving cardiovascular health.

Microalgae contain a variety of bioactive lipids with potential applications in aquaculture feed, biofuel, food and pharmaceutical industries. While microalgae-derived polyunsaturated fatty acid (PUFA) and their roles in promoting human health have been extensively studied, other lipid types from this resource, such as phytosterols, have been poorly explored. Phytosterols have been used as additives in many food products such as spread, dairy products and salad dressing. This review focuses on the recent advances in microalgae-derived phytosterols with functional bioactivities and their potential applications in functional food and pharmaceutical industries. It highlights the importance of microalgae-derived lipids other than PUFA for the development of an advanced microalgae industry. PMID:26184233

Food and agriculture commodity boards have become important funders of nutrition research. There are benefits and cautions (biases toward health benefits, failure to publish negative results, and aggressive promotion of single studies) for this activity. The California Dried Plum Board, along with other commodity boards, have developed independent Scientific Nutrition Advisory Panels to guide and evaluate the research they fund. In the case of the California Dried Plum Board, this has resulted in research that has distinguished the nature and dose of dried plum and juice to maintain bowel health and opened up a surprising new function for dried plum in the prevention of age-related bone loss.

This review focuses on the enhanced functional characteristics of enzymatic hydrolysates of whey proteins (WPHs) in food applications compared to intact whey proteins (WPs). WPs are applied in foods as whey protein concentrates (WPCs), whey protein isolates (WPIs), and WPHs. WPs are byproducts of cheese production, used in a wide range of food applications due to their nutritional validity, functional activities, and cost effectiveness. Enzymatic hydrolysis yields improved functional and nutritional benefits in contrast to heat denaturation or native applications. WPHs improve solubility over a wide range of pH, create viscosity through water binding, and promote cohesion, adhesion, and elasticity. WPHs form stronger but more flexible edible films than WPC or WPI. WPHs enhance emulsification, bind fat, and facilitate whipping, compared to intact WPs. Extensive hydrolyzed WPHs with proper heat applications are the best emulsifiers and addition of polysaccharides improves the emulsification ability of WPHs. Also, WPHs improve the sensorial properties like color, flavor, and texture but impart a bitter taste in case where extensive hydrolysis (degree of hydrolysis greater than 8%). It is important to consider the type of enzyme, hydrolysis conditions, and WPHs production method based on the nature of food application.

Developments in food science and technology have accelerated the production and availability of health foods. Although consumers may acquire health benefits from some products, they may also suffer adverse health effects and economic losses. Unlike medicine, which is administered by health professionals, foods are chosen directly by the consumer and can be used at their own discretion. Food labeling plays a major role in providing consumers with proper information when choosing the desired products; however, the food labeling system is complex and inadequately understood by consumers. Moreover, there are some products that do not follow food labeling laws and contain ingredients that have not undergone proper effectiveness and safety evaluations. With the increasing popularity of health foods, it is becoming more important to ensure that they are effective and safely used. The biggest concern is that some consumers may mistake health foods for medicines that can cure or prevent diseases. The main reason that consumers are confused and misled is due to the vast amount of information that is available. This paper provides an overview of the following four approaches that we have taken in order to develop countermeasures against health foods being used improperly by consumers: (1) conducting a survey of actual health food use; (2) collecting data on adverse events suspected to be caused by health foods, and evaluating the causal relationship with methods suited to investigating health foods; (3) examining the safety of natural ingredients used in health foods; and (4) constructing an online database that compiles information on the safety and effectiveness of health foods and/or ingredients, and sharing such information with consumers and health professionals.

The evolution of the human diet over the past 10,000 years from a Paleolithic diet to our current modern pattern of intake has resulted in profound changes in feeding behavior. Shifts have occurred from diets high in fruits, vegetables, lean meats, and seafood to processed foods high in sodium and hydrogenated fats and low in fiber. These dietary changes have adversely affected dietary parameters known to be related to health, resulting in an increase in obesity and chronic disease, including cardiovascular disease (CVD), diabetes, and cancer. Some intervention trials using Paleolithic dietary patterns have shown promising results with favorable changes in CVD and diabetes risk factors. However, such benefits may be offset by disadvantages of the Paleolithic diet, which is low in vitamin D and calcium and high in fish potentially containing environmental toxins. More advantageous would be promotion of foods and food ingredients from our ancestral era that have been shown to possess health benefits in the form of functional foods. Many studies have investigated the health benefits of various functional food ingredients, including omega-3 fatty acids, polyphenols, fiber, and plant sterols. These bioactive compounds may help to prevent and reduce incidence of chronic diseases, which in turn could lead to health cost savings ranging from $2 to $3 billion per year as estimated by case studies using omega-3 and plant sterols as examples. Thus, public health benefits should result from promotion of the positive components of Paleolithic diets as functional foods.

Evidence shows that one of the main causes for rising obesity rates is excessive consumption of sugar, which is due in large part to the high sugar content of most soda and juice drinks and junk foods. Worryingly, UK and global populations are consuming increasing amounts of sugary drinks and junk foods (high in salt, sugar and saturated fats). However, there is raised public awareness, and parents in particular want something to be done to curb the alarming rise in childhood obesity. Population-wide policies (i.e. taxation, regulation, legislation, reformulation) consistently achieve greater public health gains than interventions and strategies targeted at individuals. Junk food and soda taxes are supported by increasing evidence from empirical and modelling studies. The strongest evidence base is for a tax on sugar sweetened beverages, but in order to effectively reduce consumption, that taxation needs to be at least 20%. Empirical data from a number of countries which have implemented a duty on sugar or sugary drinks shows rapid, substantial benefits. In the UK, increasing evidence from recent scientific reports consistently support substantial reductions in sugar consumption through comprehensive strategies which include a tax. Furthermore, there is increasing public support for such measures. A sugar sweetened beverages tax will happen in the UK so the question is not 'If?' but 'When?' this tax will be implemented. And, crucially, which nation will get there first? England, Ireland, Scotland or Wales?

The disposal of food waste is a large environmental problem. In the United Kingdom (UK), approximately 15 million tonnes of food are wasted each year, mostly disposed of in landfill, via composting, or anaerobic digestion (AD). European Union (EU) guidelines state that food waste should preferentially be used as animal feed though for most food waste this practice is currently illegal, because of disease control concerns. Interest in the potential diversion of food waste for animal feed is however growing, with a number of East Asian states offering working examples of safe food waste recycling - based on tight regulation and rendering food waste safe through heat treatment. This study investigates the potential benefits of diverting food waste for pig feed in the UK. A hybrid, consequential life cycle assessment (LCA) was conducted to compare the environmental and health impacts of four technologies for food waste processing: two technologies of South Korean style-animal feed production (as a wet pig feed and a dry pig feed) were compared with two widespread UK disposal technologies: AD and composting. Results of 14 mid-point impact categories show that the processing of food waste as a wet pig feed and a dry pig feed have the best and second-best scores, respectively, for 13/14 and 12/14 environmental and health impacts. The low impact of food waste feed stems in large part from its substitution of conventional feed, the production of which has substantial environmental and health impacts. While the re-legalisation of the use of food waste as pig feed could offer environmental and public health benefits, this will require support from policy makers, the public, and the pig industry, as well as investment in separated food waste collection which currently occurs in only a minority of regions.

Purpose: Dietary variation is important for health maintenance and disease prevention among older adults. However, oral health deficits impair ability to bite and chew foods. This study examines the association between oral health and foods avoided or modified in a multiethnic rural population of older adults. It considers implications for nutrition and medical service provision to this population. Design and Methods: In-home interviews and oral examinations were conducted with 635 adults in rural North Carolina counties with substantial African American and American Indian populations. Avoidance and modification data were obtained for foods representing different dental challenges and dietary contributions. Data were weighted to census data for ethnicity and sex. Bivariate analyses of oral health measures and foods avoided used chi-square and logistic regression tests. Multivariable analyses used proportional odds or nominal regression models. Results: Whole fruits and raw vegetables were the most commonly avoided foods; substantial proportions of older adults also avoided meats, cooked vegetables, and other foods. Food avoidance was significantly associated with self-rated oral health, periodontal disease, bleeding gums, dry mouth, having dentures, and having fewer anterior and posterior occlusal contacts. Associations persisted when controlling for demographic and socioeconomic status indicators. From 24% to 68% of participants reported modifying specific fruits, vegetables, and meats. Modifying harder foods was related to location of teeth and periodontal disease and softer foods to oral pain and dry mouth. Implications: Food services for older adults should consider their oral health status. Policy changes are needed to provide oral health care in benefits for older adults. PMID:19574543

Functional foods are "foods and beverages with claimed health benefits based on scientific evidence". Health claims need to be substantiated scientifically. The future of functional foods will heavily rely on proven efficacy in well-controlled intervention studies with human volunteers. In order to have the maximum output of human trials, improvements are needed with respect to study design and optimization of study protocols. Efficacy at realistic intake levels needs to be established in studies with humans via the use of suitable biomarkers, unless the endpoint can be measured directly. The human body is able to deal with chemical entities irrespective of their origin, and the pharmaceutical terms "absorption, distribution, metabolism and excretion" have their equivalent when biomarkers are concerned. Whereas only "diurnal variation" or "circadian rhythm" is sometimes considered, little attention is paid to "kinetics of biomarkers". "Kinetics of biomarkers" comprises "formation, distribution, metabolism and excretion". However, this is at present neither an established science nor common practice in nutrition research on functional foods. As a consequence, sampling times and matrices, for example, are chosen on the basis of historical practice and convenience (for volunteers and scientists) but not on the basis of in depth insight. The concept of kinetics of biomarkers is illustrated by a variety of readily comprehensible examples, such as malaria, cholesterol, polyphenols, glutathione-S-transferase alpha, F2-isoprostanes, interleukin-6, and plasma triacylglycerides.

Observed changes in eating and drinking behaviors in economically developing countries is associated to the increase of obesity and related chronic diseases. Researchers from Public Health (PH) field have attributed this problem to food processing and have created new food classification systems to support their thesis. These classifications conceptually differ from processing level concepts in Food Science and states to people that food processing is directly related to nutritional impact of food. Our work aims to compare the concept of food processing from the standpoints of Food Science and Technology (FST) and of PH as well as to discuss differences related to formulation or level of processing of products and their impact on nutritional quality. There is a misconception among food processing/unit operation /food technology and formulation or recipes. For the PH approach, classification is based on food products selection and the use of ingredients that results in higher consumption of sugar, sodium, fat and additives, whereas in FST, processing level is based on the intensity and amount of unit operations to enhance shelf life, food safety, food quality and availability of edible parts of raw materials. Nutritional quality of a product or preparation is associated to formulation/recipe and not to the level of processing, with few exceptions. The impact of these recommendations on the actual comprehension of food processing and quality by the population must be considered.

Food fortification can deliver essential micronutrients to large population segments without modifications in consumption pattern, suggesting that fortified foods may be formulated for populations at risk for fragility fractures. This scoping review determined the extent to which randomized controlled studies have been carried out to test the impact of fortified foods on bone outcomes, searching PubMed for all studies using the terms ‘fortified AND bone', and ‘fortification AND bone'. Studies were restricted to English language, published between 1996 and June 2015. From 360 articles, 24 studies met the following criteria: human study in adults ⩾18 years (excluding pregnancy or lactation); original study of a fortified food over time, with specific bone outcomes measured pre- and post intervention. Six studies involved adults <50 years; 18 involved adults ⩾50 years. Singly or in combination, 17 studies included calcium and 16 included vitamin D. There were 1 or 2 studies involving either vitamin K, magnesium, iron, zinc, B-vitamins, inulin or isoflavones. For adults <50 years, the four studies involving calcium or vitamin D showed a beneficial effect on bone remodeling. For adults ⩾50 years, n=14 provided calcium and/or vitamin D, and there was a significant bone turnover reduction. No consistent effects were reported in studies in which addition of vitamin K, folic acid or isoflavone was assessed. Results from this scoping review indicate that up to now most studies of fortification with bone health have evaluated calcium and/or vitamin D and that these nutrients show beneficial effects on bone remodeling.

There is a growing interest in using trait-based approaches to characterize the functional structure of animal communities. Quantitative methods have been derived mostly for plant ecology, but it is now common to characterize the functional composition of various systems such as soils, coral reefs, pelagic food webs or terrestrial vertebrate communities. With the ever-increasing availability of distribution and trait data, a quantitative method to represent the different roles of animals in a community promise to find generalities that will facilitate cross-system comparisons. There is, however, currently no theory relating the functional composition of food webs to their dynamics and properties. The intuitive interpretation that more functional diversity leads to higher resource exploitation and better ecosystem functioning was brought from plant ecology and does not apply readily to food webs. Here we appraise whether there are interpretable metrics to describe the functional composition of food webs that could foster a better understanding of their structure and functioning. We first distinguish the various roles that traits have on food web topology, resource extraction (bottom-up effects), trophic regulation (top-down effects), and the ability to keep energy and materials within the community. We then discuss positive effects of functional trait diversity on food webs, such as niche construction and bottom-up effects. We follow with a discussion on the negative effects of functional diversity, such as enhanced competition (both exploitation and apparent) and top-down control. Our review reveals that most of our current understanding of the impact of functional trait diversity on food web properties and functioning comes from an over-simplistic representation of network structure with well-defined levels. We, therefore, conclude with propositions for new research avenues for both theoreticians and empiricists.

Collecting adverse case reports suspected to be due to health foods and evaluation of the causality are important to secure safety, even if the causal relationship between health foods and reported health problem is uncertain. Case reports are mainly collected at three sites: public health centers, practical living information online network system(PIO-NET), and individual companies. The case reports from the three sources are not dealt with consistently. In this study, we investigated and characterized those case reports from the viewpoint of evaluating causality, using the causality association rating methods, namely, the dendritic and pointed methods, which we reported previously. Information in public health centers comprised 20 reports per year; approximately 40% were from health care providers and contained detailed medical data. PIO-NET information comprised 366 reports per year; 80% were self-reports from users, and few medical details were included. Company information covered 1,323 cases from 13 companies; more than 90% were from users and most of them were complaints. Case reports from public health centers and PIO-NET showed that the largerst number of victims were female aged >60, with allergy and gastrointestinal symptoms. When these case reports from the letter two sources were examined using the causality association rating systems, most were rated as "possible" and only a few were rated as "probable". As specific case reports from different information sources were examined in this study, we were able to identify several points that should be improved in our two rating methods. However, to ensure the safety of health foods, it will be necessary to collect a large number of high-quality case reports for evaluation by a suitable causality rating method, and to integrate those evaluated case reports into a single site.

Dietary- and lifestyle-related diseases are problems of epidemic proportion in the Federated States of Micronesia (FSM). Public health resources to help prevent nutrition-related problems are limited. There is also concern about biodiversity, neglect of traditional staple foods, and threatened loss of traditional knowledge. A "Go Local" campaign was initiated to increase production and consumption of locally grown foods, for their Culture, Health, Environment, Economics, and Food security ("CHEEF") benefits. To provide updates and discuss local island food topics, the Island Food Community of Pohnpei launched an interagency email network in 2003. Interested members' email addresses were recorded in distribution lists, weekly/bi-weekly emails were sent and from these messages, a database was organized to record email topic details. An analysis of all emails up to July 2009 showed that membership had expanded to over 600 listed people from all FSM states, other Pacific Island countries and beyond. Information was shared on topics ranging from scientific findings of carotenoid content in local island food cultivars, to discussions on how daily habits related to island food use can be improved. Over 200 men and women, aged 22 to 80 years, contributed items, some indicating that they had shared emails to a further network at their workplace or community. In conclusion, this email network is a simple, cost-effective method to share information, create awareness, and mobilize island food promotion efforts with potential for providing health, biodiversity and other benefits of island foods to populations in the FSM and other countries.

Purpose Functional impairment is a key indicator of need for mental health services among children and adolescents, often a stronger predictor of service usage than mental health symptoms themselves. Functional impairment may be of particular importance in low and middle income countries (LMIC) because of its potential to focus policy on treatment of child mental health problems which is generally given low priority in LMIC. However, few studies have assessed functional impairment in LMIC. The present study assessed rates of functional impairment among children in Vietnam, as a case example of an LMIC, as well as effects of other risk/protective factors of particular relevance to LMIC (e.g., whether the family lived in an urban or rural area; family structure variables such as grandparents living with the family). Methods 1,314 parents of children 6–16 years old from 10 Vietnamese provinces were interviewed. Results The overall rate of functional impairment among Vietnamese children was 20%, similar to rates in high income countries such as Germany and the United States, suggesting that LMIC status may not be associated with dramatic increases in functional impairment in children. Functional impairment was significantly greater among mental health cases than non-cases, with increases of over 550% associated with mental health caseness. A number of other risk factors (e.g., marital status) had smaller but significant effects. Conclusions Mental health problems are a major but not the sole contributor to functional impairment among Vietnamese children. The pragmatic significance of this research lies in its potential to affect public awareness and policy related to child mental health in LMIC. PMID:26315942

Polydextrose (PDX) is a non-digestible oligosaccharide used widely across most sectors of the food industry. It is a randomly linked glucose oligomer containing small amounts of sorbitol and citric acid. The random bonds in PDX prevent mammalian digestive enzymes from readily hydrolyzing the molecule and it has a reported energy value of 1 kcal/g. These properties have led to the acceptance in many countries that PDX provides similar physiological effects as other dietary fibers and has shown prebiotic potential. Dietary intervention with prebiotics has been shown to selectively stimulate the growth and/or activity of one or a limited number of intestinal bacteria associated with several physiological benefits on health. Therefore, the objective of this review was a survey of the literature on the effect of supplementation with PDX in health, and to list the benefits for maintaining health and/or reducing the development of diseases.

Immunoglobulin A (IgA) is an anti-inflammatory antibody that plays a critical role in mucosal immunity. It is found in large quantities in human milk, but there are lower amounts in bovine milk. In humans, IgA plays a significant role in providing protection from environmental pathogens at mucosal surfaces and is a key component for the establishment and maintenance of intestinal homeostasis via innate and adaptive immune mechanisms. To date, many of the dairy-based functional foods are derived from bovine colostrum, targeting the benefits of IgG. IgA has a higher pathogenic binding capacity and greater stability against proteolytic degradation when ingested compared with IgG. This provides IgA-based products greater potential in the functional food market that has yet to be realized.

General job training programs, and separate disease prevention or health promotion programs, are usually viewed as two different strategies for reducing poverty and promoting community development. We propose that with better alignment of the strategies, new jobs with the potential to simultaneously improve population health, lower the cost of health care, and reduce unemployment could be created and filled. Initiatives for three types of entry-level positions-in the fields of community health, environmental remediation and protection, and food preparation-show particular promise as vehicles for health and economic improvement at the individual and community levels. Building on current federal programs, new pilot projects financed by federal funding should be created to test and refine such initiatives and their impact and assemble an evidence base for future policy action.

Everyday great amounts of food are produced, processed, transported by the food industry and consumed by us and these activities have direct impact on our health and the environment. The current food system has started causing strain on the Earth's natural resources and that is why sustainable food production systems are needed. This review article discusses the need for sustainable diets by exploring the interactions between the food industry, nutrition, health and the environment, which are strongly interconnected. The most common environmental issues in the food industry are related to food processing loss, food wastage and packaging; energy efficiency; transportation of foods; water consumption and waste management. Among the foods produced and processed, meat and meat products have the greatest environmental impact followed by the dairy products. Our eating patterns impact the environment, but the environment can impact dietary choices as well. The foods and drinks we consume may also affect our health. A healthy and sustainable diet would minimise the consumption of energy-dense and highly processed and packaged foods, include less animal-derived foods and more plant-based foods and encourage people not to exceed the recommended daily energy intake. Sustainable diets contribute to food and nutrition security, have low environmental impacts and promote healthy life for present and future generations. There is an urgent need to develop and promote strategies for sustainable diets; and governments, United Nations agencies, civil society, research organisations and the food industry should work together in achieving this.

This review concerns the issues of foodfortifications and the creation of functional foods (FF) and food supplements based on probiotics and covers an issue of approaches to the regulation of probiotic food products in various countries. The status of functional foods, optimizing GIT functions, as a separate category of FF is emphasized. Considering the strain-specificity effect of probiotics, the minimum criteria used for probiotics in food products are: 1) the need to identify a probiotics at genus, species, and strain levels, using the high-resolution techniques, 2) the viability and the presence of a sufficient amount of the probiotic in product at the end of shelf life, 3) the proof of functional characteristics inherent to probiotic strains, in the controlled experiments. The recommended by FA O/WHO three-stage evaluation procedure offunctional efficiency of FF includes: Phase I--safety assessment in in vitro and in vivo experiments, Phase II--Evaluation in the Double-Blind, Randomized, Placebo-Controlled trial (DBRPC) and Phase III--Post-approval monitoring. It is noted that along with the ability to obtain statistically significant results of the evaluation, there are practical difficulties of conducting DBRPC (duration, costs, difficulties in selection of target biomarkers and populations). The promising approach for assessing the functional efficacy of FF is the concept of nutrigenomics. It examines the link between the human diet and the characteristics of his genome to determine the influence of food on the expression of genes and, ultimately, to human health. Nutrigenomic approaches are promising to assess the impact of probiotics in healthy people. The focusing on the nutrigenomic response of intestinal microbial community and its individual populations (in this regard the lactobacilli can be very informative) was proposed.

Food sovereignty has been defined as “the right of peoples to healthy and culturally appropriate food produced through ecologically sound and sustainable methods, and their right to define their own food and agriculture systems.” Human health is an implied component of this definition through the principle of healthy food. In fact, improved human health is commonly cited as a benefit of transforming food production away from the dominant practices of industrial agriculture. Yet, does the use of “ecologically sound and sustainable methods” of food production necessarily translate into better human health outcomes? Does greater choice in defining an agricultural or food system create gains in health and well-being? We elucidate the conceptual linkages between food sovereignty and human health, critically examine the empirical evidence supporting or refuting these linkages, and identify research gaps and key priorities for the food sovereignty-human health research agenda. Five domains of food sovereignty are discussed including: (1) use of agroecological management practices for food production, (2) the localization of food production and consumption, (3) promotion of social justice and equity, (4) valuation of traditional knowledge, and (5) the transformation of economic and political institutions and structures to support self-determination. We find that although there are many plausible linkages between food sovereignty and human health, the empirical evidence in support of the hypothesis that increasing food sovereignty yields improvements to human health is weak. We propose that a concerted effort to generate new empirical evidence on the health implications of these domains of food sovereignty is urgently needed, and suggest areas of research that may be crucial for addressing the gaps in the evidence base.

Although it has been traditionally regarded as an intermediate of carbon metabolism and major component of fermented dairy products contributing to organoleptic and antimicrobial properties of food, there is evidence gathered in recent years that lactate has bioactive properties that may be responsible of broader properties of functional foods. Lactate can regulate critical functions of several key players of the immune system such as macrophages and dendritic cells, being able to modulate inflammatory activation of epithelial cells as well. Intraluminal levels of lactate derived from fermentative metabolism of lactobacilli have been shown to modulate inflammatory environment in intestinal mucosa. The molecular mechanisms responsible to these functions, including histone deacetylase dependent-modulation of gene expression and signaling through G-protein coupled receptors have started to be described. Since lactate is a major fermentation product of several bacterial families with probiotic properties, we here propose that it may contribute to some of the properties attributed to these microorganisms and in a larger view, to the properties of food products fermented by lactic acid bacteria.

The rhythm of life on earth is shaped by seasonal changes in the environment. Plants and animals show profound annual cycles in physiology, health, morphology, behaviour and demography in response to environmental cues. Seasonal biology impacts ecosystems and agriculture, with consequences for humans and biodiversity. Human populations show robust annual rhythms in health and well-being, and the birth month can have lasting effects that persist throughout life. This review emphasizes the need for a better understanding of seasonal biology against the backdrop of its rapidly progressing disruption through climate change, human lifestyles and other anthropogenic impact. Climate change is modifying annual rhythms to which numerous organisms have adapted, with potential consequences for industries relating to health, ecosystems and food security. Disconcertingly, human lifestyles under artificial conditions of eternal summer provide the most extreme example for disconnect from natural seasons, making humans vulnerable to increased morbidity and mortality. In this review, we introduce scenarios of seasonal disruption, highlight key aspects of seasonal biology and summarize from biomedical, anthropological, veterinary, agricultural and environmental perspectives the recent evidence for seasonal desynchronization between environmental factors and internal rhythms. Because annual rhythms are pervasive across biological systems, they provide a common framework for trans-disciplinary research. PMID:26468242

Pasta, a delicious meal favorite and the signature dish of many of the world's most famous chefs and a bonding comfort meal for millions all over the world, it has been recognized as an identifying ingredient of traditional healthy Mediterranean and Latin American meals. Pasta has come a long way from the days when it was erroneously considered by consumers to be a "fattening food." Today it is perceived as one of the "healthy options." In fact, because pasta is so supremely versatile as a base to a meal, it is easily possible to serve it in ways to satisfy both our notions of "healthy eating" and our appetites for interesting and tasty food. Pasta, being so popular as a delicious family meal favorite and equally relished all over the world, it deserves a lot than any other food to serve as an ideal functional food. Here we analyze various health ingredients that have been incorporated in pasta as disease/disorder curing agents and/or potent nutritional supplements and their effects on cooking and quality parameters of pasta as well as their various health benefits and therapeutic attributes.

The Federated States of Micronesia (FSM) and other countries throughout the Pacific are facing an epidemic of non-communicable disease health problems. These are directly related to the increased consumption of unhealthy imported processed foods, the neglect of traditional food systems, and lifestyle changes, including decreased physical activity. The FSM faces the double burden of malnutrition with both non-communicable diseases and micronutrient deficiencies, including vitamin A deficiency and anemia. To help increase the use of traditional island foods and improve health, the Island Food Community of Pohnpei has initiated a program in the FSM to support and promote local food policies, along with its Go Local awareness campaign. Such local food policies are defined broadly and include individual and family commitments, community group local food policies and policies established by government, including presidential proclamations and increased taxation on soft drinks. The aim of this paper is to describe this work. An inter-agency, community- and research-based, participatory and media approach was used. Partners are both non-governmental and governmental. The use of continuing awareness work along with local food policy establishment and the acknowledgement of the individuals and groups involved are essential. The work is still in the preliminary stage but ad hoc examples show that this approach has had success in increased awareness on health issues and improving dietary intake on both an individual and group basis. This indicates that further use of local food policies could have an instrumental impact in FSM as well as other Pacific Island countries in promoting local foods and improving dietary intake and health, including the control of non-communicable diseases and other dietary-related health problems.

A focus group process, conducted by a community-academic partnership, qualitatively assessed food insecurity perspectives of parents and community staff assisting families with food assistance. Food insecurity was reported to affect all aspects of their life, increasing stress and reducing coping abilities. The Agency for Healthcare Research and Quality encourages research with priority populations, including low-income populations. This research supports the body of knowledge correlating relationships between poverty, food insecurity, and chronic health conditions. Perspectives of food-insecure people are often missing from policy and advocacy interventions. Nurses can use lessons learned and recommendations from this research to address food-insecurity-related health disparities.
The 2015 Advanced Environmental Health/Advanced Food Technology (AEH/AFT) Standing Review Panel (from here on referred to as the SRP) met for a site visit in Houston, TX on December 14 - 15, 2015. The SRP met with representatives from the Space Human Factors and Habitability (SHFH) Element and members of the Human Research Program (HRP) to review the updated research plans for the Risk of Adverse Health Effects Due to Host-Microorganism Interactions (MicroHost Risk) and the Risk of Performance Decrement and Crew Illness due to an Inadequate Food System (Food Risk). During the meeting, the SRP also met with the vehicle engineers to discuss possible food storage options. The SRP would like to commend Dr. Oubre and Dr. Douglas for their detailed presentations, as well the frank, refreshing, and comprehensive engineering presentation. This gave much needed perspective to the food storage issues and reassured the committee about NASA's approach to the problem. In terms of critiques, the SRP remains unconvinced about the rationale for probiotic use other than for specific applications supported by the literature. It is not clear what gap or problem is being addressed by the use of probiotics, and the rationale for their use needs to be clearly rooted in the available literature. The SRP thinks that if low-Earth orbit is associated with immune system impairment, then there may additional risks linked with the use of probiotics. It is not clear to the SRP how NASA will determine if probiotics are having their intended beneficial effect. A similar concern is raised as to what gaps or problems are being addressed by "functional foods". Mixed infections, rather than single species infections, which can augment severity of disease, also represent a significant concern. Overall, the SRP considers this to be a strong program that is well-organized, well-coordinated and generates valuable data.

Having entered the genomics era with confidence in the future of medicine, including psychiatry, identifying the role of DNA and polymorphic associations with brain reward circuitry has led to a new understanding of all addictive behaviors. It is noteworthy that this strategy may provide treatment for the millions who are the victims of “Reward Deficiency Syndrome” (RDS) a genetic disorder of brain reward circuitry. This article will focus on drugs and food being mutuality addictive, and the role of dopamine genetics and function in addictions, including the interaction of the dopamine transporter, and sodium food. We will briefly review our concept that concerns the genetic antecedents of multiple–addictions (RDS). Studies have also shown that evaluating a panel of established reward genes and polymorphisms enables the stratification of genetic risk to RDS. The panel is called the “Genetic Addiction Risk Score (GARS)”, and is a tool for the diagnosis of a genetic predisposition for RDS. The use of this test, as pointed out by others, would benefit the medical community by identifying at risk individuals at a very early age. We encourage, in depth work in both animal and human models of addiction. We encourage further exploration of the neurogenetic correlates of the commonalities between food and drug addiction and endorse forward thinking hypotheses like “The Salted Food Addiction Hypothesis”.

technologies, such as milling, sieving, and debranning or pearling. Finally, cereal constituents, such as starch, can be used as encapsulation materials for probiotics in order to improve their stability during storage and enhance their viability during their passage through the adverse conditions of the gastrointestinal tract. It could be concluded that functional foods based on cereals is a challenging perspective, however, the development of new technologies of cereal processing that enhance their health potential and the acceptability of the food product are of primary importance.

This study provides a spatial analysis of distribution and access to commercial fruit and vegetable establishments within the territory of a representative sample of public fitness facilities known as the Health Academy Program (HAP) in Belo Horizonte, Minas Gerais State, Brazil. The study evaluated commercial food establishments within a buffer area based on a radius of 1,600 meters around each of 18 randomly selected fitness facilities. Quality of access to fruits and vegetables was assessed by the Healthy Food Store Index (HFSI), consisting of the variables availability, variety, and advertising of fruits, vegetables and ultra-processed foods. The analysis was based on calculation of the Kernel intensity estimator, nearest neighbor method, and Ripley K-function. Of the 336 food establishments, 61.3% were green grocers and open-air markets, with a median HFSI of 11 (5 to 16). In only 17% of the territories, the majority of the "hot area" establishments displayed better access to healthy foods, and only three areas showed a clustering pattern. The study showed limited access to commercial establishments supplying healthy fruits and vegetables within the territory of the public fitness program.

Some dietary proteins cause specific effects going beyond nutrient supply. A number of proteins seem to act directly in the intestine, such as IGFs, lactoferrin and immunoglobulins. Many substances, however, are peptides encrypted in intact molecules and are released from their encrypted position by enzymes during gastrointestinal transit or by fermentation or ripening during food processing. Among food-derived bioactive proteins and peptides from plants and animals, those obtained from milk are known in particular. Numerous effects have been described after in vitro and animal trials for bioactive proteins and peptides, such as immunomodulating, antihypertensive, osteoprotective, antilipemic, opiate, antioxidative and antimicrobial. This article reviews the current knowledge of the existence of bioactive proteins and of in vitro bioactivity and the present evidence of health effects exerted by such substances or products containing bioactive compounds. For example, there is evidence for the antihypertensive effects of milk products fermented with Lactobacillus helveticus containing the tripeptides IPP and VPP, which inhibit angiotensin converting enzyme, and for osteoprotective effects by milk basic protein. There is less profound evidence on the immunomodulating effects of lactoferrin and postprandial triglyceride reduction by a hydrolysate of bovine hemoglobin.

The recent developments of metagenomics permit an extremely high-resolution molecular scan of the intestinal microbiota giving new insights and opening perspectives for clinical applications. Beyond the unprecedented vision of the intestinal microbiota given by large-scale quantitative metagenomics studies, such as the EU MetaHIT project, functional metagenomics tools allow the exploration of fine interactions between food constituents, microbiota and host, leading to the identification of signals and intimate mechanisms of crosstalk, especially between bacteria and human cells. Cloning of large genome fragments, either from complex intestinal communities or from selected bacteria, allows the screening of these biological resources for bioactivity towards complex plant polymers or functional food such as prebiotics. This permitted identification of novel carbohydrate-active enzyme families involved in dietary fibre and host glycan breakdown, and highlighted unsuspected bacterial players at the top of the intestinal microbial food chain. Similarly, exposure of fractions from genomic and metagenomic clones onto human cells engineered with reporter systems to track modulation of immune response, cell proliferation or cell metabolism has allowed the identification of bioactive clones modulating key cell signalling pathways or the induction of specific genes. This opens the possibility to decipher mechanisms by which commensal bacteria or candidate probiotics can modulate the activity of cells in the intestinal epithelium or even in distal organs such as the liver, adipose tissue or the brain. Hence, in spite of our inability to culture many of the dominant microbes of the human intestine, functional metagenomics open a new window for the exploration of food-microbe-host crosstalk.

The "organic" claim explicitly informs consumers about the food production method. Yet, based on this claim, people often infer unrelated food attributes. The current research examined whether the perceived advantage of organic over conventional food generalizes across different organic food types. Compared to whole organic foods, processed organic foods are less available, familiar and prototypical of the organic food category. In two studies (combined N = 258) we investigated how both organic foods types were perceived in healthfulness, taste and caloric content when compared to their conventional alternatives. Participants evaluated images of both whole (e.g., lettuce) and processed organic food exemplars (e.g., pizza), and reported general evaluations of these food types. The association of these evaluations with individual difference variables - self-reported knowledge and consumption of organic food, and environmental concerns - was also examined. Results showed that organically produced whole foods were perceived as more healthful, tastier and less caloric than those produced conventionally, thus replicating the well-established halo effect of the organic claim in food evaluation. The organic advantage was more pronounced among individuals who reported being more knowledgeable about organic food, consumed it more frequently, and were more environmentally concerned. The advantage of the organic claim for processed foods was less clear. Overall, processed organic (vs. conventional) foods were perceived as tastier, more healthful (Study 1) or equally healthful (Study 2), but also as more caloric. We argue that the features of processed food may modulate the impact of the organic claim, and outline possible research directions to test this assumption. Uncovering the specific conditions in which food claims bias consumer's perceptions and behavior may have important implications for marketing, health and public-policy related fields.

Cardiovascular disease (CVD) is a major cause of death and disability in many developed countries. The purpose of this literature review is to establish a recommendation for the intake of functional food ingredients in a healthy diet--such as plant sterols (PSs) in low-fat and functional matrices, fatty acid composition and other nutrients of tree nuts and flavonoids in dark chocolate--for the prevention and treatment of CVD. These three specific functional foods are explored in this review, since there is a higher potential for their increased consumption by the population to prevent CVD. First, PS have been added to various nontraditional matrices, such as low-fat products and functional oils, which have shown cholesterol-lowering effects in most clinical trials. Secondly, a growing number of clinical studies indicate that the beneficial effect of tree nuts may not only be due to their fatty acid composition but to other key nutrients, which may provide supplementary health benefits, such as endothelial cell function, as well as decreasing total cholesterol and low-density lipoprotein cholesterol (LDL-C). Lastly, flavonoids in dark chocolate may protect LDL-C particles from undergoing oxidative modification. However, some gaps in our knowledge need to be filled before firm recommendations can be made for habitual dark chocolate consumption. Overall, these functional foods should be considered as an addition to current lipid-lowering recommendations for improving CVD risk.

Being naturally enriched in key nutrients and in various health-promoting compounds, seaweeds represent promising candidates for the design of functional foods. Soluble dietary fibers, peptides, phlorotannins, lipids and minerals are macroalgae’s major compounds that can hold potential in high-value food products derived from macroalgae, including those directed to the cardiovascular-health promotion. This manuscript revises available reported data focusing the role of diet supplementation of macroalgae, or extracts enriched in bioactive compounds from macroalgae origin, in targeting modifiable markers of cardiovascular diseases (CVDs), like dyslipidemia, oxidative stress, vascular inflammation, hypertension, hypercoagulability and activation of the sympathetic and renin-angiotensin systems, among others. At last, the review also describes several products that have been formulated with the use of whole macroalgae or extracts, along with their claimed cardiovascular-associated benefits. PMID:26569268

This paper presents the results of a research in urban ethnobotany, conducted in a market of Bolivian immigrants in the neighborhood of Liniers, Ciudad Autónoma de Buenos Aires (Argentina). Functional foods and nutraceuticals belonging to 50 species of 18 families, its products, and uses were recorded. Some products are exclusive from the Bolivian community; others are frequent within the community, but they are also available in the general commercial circuit; they are introduced into it, generally, through shops called dietéticas (“health-food stores”), where products associated with the maintenance of health are sold. On this basis, the traditional and nontraditional components of the urban botanical knowledge were evaluated as well as its dynamics in relation to the diffusion of the products. Both the framework and methodological design are innovative for the studies of the urban botanical knowledge and the traditional markets in metropolitan areas. PMID:22203866

Biguanides such as metformin are widely used worldwide for the treatment of type-2 diabetes. The identification of guanidine and related compounds in French lilac plant (Galega officinalis L.) led to the development of biguanides. Despite of their plant origin, biguanides have not been reported in plants. The objective of this study was to quantify biguanide related compounds (BRCs) in experimentally or clinically substantiated antidiabetic functional plant foods and potatoes. The corrected results of the Voges-Proskauer (V-P) assay suggest that the highest amounts of BRCs are present in green curry leaves (Murraya koenigii (L.) Sprengel) followed by fenugreek seeds (Trigonella foenum-graecum L.), green bitter gourd (Momordica charantia Descourt.), and potato (Solanum tuberosum L.). Whereas, garlic (Allium sativum L.), and sweet potato (Ipomea batatas (L.) Lam.) contain negligible amounts of BRCs. In addition, the possible biosynthetic routes of biguanide in these plant foods are discussed.

Objective Explicitly—as opposed to subtly—labeling a food healthy may inadvertently license people to indulge, imply that the food tastes bad, or lead to reactance. We investigated the effects of explicit and subtle health messages on individuals’ food selection in two field studies. Methods We manipulated the signs on healthy foods such that they explicitly stated that the food was healthy, subtly suggested it with an image, or did not mention health. As participants, attendees at academic conferences, approached registration tables, research assistants recorded the number and type of snacks individuals chose. Results Participants were more likely to choose the healthy food when it was labeled with the subtle health message than when it was labeled with the explicit health message, which itself was not more effective than the control message. Conclusion Subtle messages may be more useful than explicit health messages in encouraging individuals to make a healthy snack choice. PMID:24467259

Background Mental resilience can be seen as a trait that enables an individual to recover from stress and to face the next stressor with optimism. People with resilient traits are considered to have a better mental and physical health. However, there are limited data available assessing the relationship between resilient individuals and their perspective of their health and immune status. Therefore, this study was conducted to examine the relationship between mental resilience, perceived health, and perceived immune status. Methods A total of 779 participants recruited at Utrecht University completed a questionnaire consisting of demographic characteristics, the brief resilience scale for the assessment of mental resilience, the immune function questionnaire (IFQ), and questions regarding their perceived health and immune status. Results When correcting for gender, age, height, weight, smoker status, amount of cigarettes smoked per week, alcohol consumption status, amount of drinks consumed per week, drug use, and frequency of past year drug use, mental resilience was significantly correlated with perceived health (r=0.233, p=0.0001), perceived immune functioning (r=0.124, p=0.002), and IFQ score (r=−0.185, p=0.0001). Conclusion A significant, albeit modest, relationship was found between mental resilience and perceived immune functioning and health. PMID:28356753

The present study focused on the role of the Health Belief Model (HBM) in predicting willingness to use functional breads, across four European countries: UK (N=552), Italy (N=504), Germany (N=525) and Finland (N=513). The behavioural evaluation components of the HBM (the perceived benefits and barriers conceptualized respectively as perceived healthiness and pleasantness) and the health motivation component were good predictors of willingness to use functional breads whereas threat perception components (perceived susceptibility and perceived anticipated severity) failed as predictors. This result was common in all four countries and across products. The role of 'cue to action' was marginal. On the whole the HBM fit was similar across the countries and products in terms of significant predictors (the perceived benefits, barriers and health motivation) with the exception of self-efficacy which was significant only in Finland. Young consumers seemed more interested in the functional bread with a health claim promoting health rather than in reducing risk of disease, whereas the opposite was true for older people. However, functional staple foods, such as bread in this European study, are still perceived as common foods rather than as a means of avoiding diseases. Consumers seek these foods for their healthiness (the perceived benefits) as they expect them to be healthier than regular foods and for the pleasantness (the perceived barriers) as they do not expect any change in the sensory characteristics due to the addition of the functional ingredients. The importance of health motivation in willingness to use products with health claims implies that there is an opening for developing better models for explaining health-promoting food choices that take into account both food and health-related factors without making a reference to disease-related outcome.

The rise in food prices since 2007 is widely recognized as signaling a crisis of food insecurity among the world's poor. Scholars sought to chart the impacts of the crisis on food insecurity by conducting simulation studies, assessing anthropometric outcomes, and evaluating shifts in experience-based measures of food security. Few studies, however, have investigated the broader impacts on those most vulnerable and how rapid rises in food prices play out in the everyday lives of those most impacted. We used qualitative methods to investigate the impact of the rise in food prices on the urban poor in Ethiopia. Twenty semi-structured interviews were conducted in August 2011, in the provincial town of Jimma. Themes identified in these interviews included coping strategies, consumption priorities, and impacts on institutional networks of sharing. Our results suggest that several important cultural practices, including funerals and coffee ceremonies, were undermined by the rise in prices, and that respondents linked food prices to increasing food insecurity, which they in turn linked to high levels of stress, poor mental health, and reduced physical health. Our results are consistent with several other studies that suggest that food insecurity has a range of non-nutritional consequences, and that these are due in part to the highly social nature of food. Recognizing the effects of food insecurity on dimensions of everyday life such as interaction with neighbors, and feelings of shame, draws attention to the potential for food price increases to have erosive effects on communal social capital, and to increase the vulnerability of affected peoples to future shocks.

The health relevance of dairy products has mostly been judged by their abundant nutrients (protein, calcium and riboflavin) and recommendations for these derived in lactase-persistent Caucasian populations. Extrapolation to Asians who are generally lactase non-persisters may not be biologically, culturally or environmentally sound. A number of studies, especially among north-east Asians as in Taiwan, provide guidance for their optimal dairy intakes. In Taiwan, the NAHSIT (Nutrition and Health Surveys in Taiwan) linked to the National Health Insurance and Death Registry data bases provide most of the evidence. Cultural and socio-economic barriers create population resistance to increase dairy consumption beyond one serving per day as reflected in food balance sheet and repeat survey trend analyses. For the morbidity and mortality patterns principally seen in Asia, some, but not too much, dairy is to be preferred. This applies to all-cause and cardiovascular, especially stroke, mortality, to the risk of overfatness (by BMI and abdominal circumference) and diabetes and very likely to fracture and its sequelae. In Taiwan, there is no apparent association with total cancer mortality, but among Europeans, there may be protection. Historically, while fermented mammalian milks have been consumed in south Asia and various Asian subgroups and regions, most of the uptake of dairy in Asia after World War 2 has been from imported powdered milk or fresh liquid milk, encouraged further by the use of yogurts and popularization of milk teas and coffee. Asian dietary guidelines and clinical nutrition protocols need to encourage a modest, asymptomatic dairy intake.

Health care leaders are broadening their awareness to include the need to address the food system as a means to individual, public, and global health, above and beyond basic nutritional factors. Key voices from the health care sector have begun to engage in market transformation and are aggregating to articulate the urgency for engagement in food and agricultural policy. Systemic transformation requires a range of policies that complement one another and address various aspects of the food system. Health care involvement in policy and advocacy is vital to solve the expanding ecological health crises facing our nation and globe and will require an urgency that may be unprecedented.

The marine environment represents a relatively untapped source of functional ingredients that can be applied to various aspects of food processing, storage, and fortification. Moreover, numerous marine-based compounds have been identified as having diverse biological activities, with some reported to interfere with the pathogenesis of diseases. Bioactive peptides isolated from fish protein hydrolysates as well as algal fucans, galactans and alginates have been shown to possess anticoagulant, anticancer and hypocholesterolemic activities. Additionally, fish oils and marine bacteria are excellent sources of omega-3 fatty acids, while crustaceans and seaweeds contain powerful antioxidants such as carotenoids and phenolic compounds. On the basis of their bioactive properties, this review focuses on the potential use of marine-derived compounds as functional food ingredients for health maintenance and the prevention of chronic diseases.

The U.S. Household Food Security Scale, developed with federal support for use in national surveys, is an effective research tool. This study uses these new measures to examine associations between food insecurity and health outcomes in young children. The purpose of this study was to determine whether household food insecurity is associated with adverse health outcomes in a sentinel population ages < or = 36 mo. We conducted a multisite retrospective cohort study with cross-sectional surveys at urban medical centers in 5 states and Washington DC, August 1998-December 2001. Caregivers of 11,539 children ages < or = 36 mo were interviewed at hospital clinics and emergency departments (ED) in central cities. Outcome measures included child's health status, hospitalization history, whether child was admitted to hospital on day of ED visit (for subsample interviewed in EDs), and a composite growth-risk variable. In this sample, 21.4% of households were food insecure (6.8% with hunger). In a logistic regression, after adjusting for confounders, food-insecure children had odds of "fair or poor" health nearly twice as great [adjusted odds ratio (AOR) = 1.90, 95% CI = 1.66-2.18], and odds of being hospitalized since birth almost a third larger (AOR = 1.31, 95% CI = 1.16-1.48) than food-secure children. A dose-response relation appeared between fair/poor health status and severity of food insecurity. Effect modification occurred between Food Stamps and food insecurity; Food Stamps attenuated (but did not eliminate) associations between food insecurity and fair/poor health. Food insecurity is associated with health problems for young, low-income children. Ensuring food security may reduce health problems, including the need for hospitalizations.

Ethnic minority populations in the United States are disproportionately affected by obesity. To address this disparity, research has begun to investigate the role of culture, ethnicity, and experiences with racism on food choices and health interventions. The aim of the current study was to develop and evaluate a new scale measuring the extent to which individuals' culture, as they perceive it, influences perceptions of food-related health messages. A diverse sample of 422 college students responded to the item pool, as well as surveys on race-related stress, self-efficacy in making healthy food choices, ethnic identity, and social support for health-related behaviors. Exploratory and confirmatory factor analyses produced a five-factor model: Connection (the extent to which food connected individuals with their culture), Authority (beliefs that health care providers were familiar with individuals' cultural foods), Unhealthy Food Perceptions (beliefs that individuals' cultural foods were perceived as unhealthy), Healthy Food Perceptions (beliefs that others perceive individuals' cultural foods to be healthy), and Social Value (the extent to which social relationships are improved by shared cultural food traditions). Authority and Healthy Food Perceptions were related to individuals' confidence in their ability to make healthy food choices. Authority was inversely correlated with negative coping with racism-related events. Ethnic identity was significantly correlated with all but Unhealthy Food Perceptions. Race/ethnicity differences were identified for Healthy Food Perceptions, Unhealthy Food Perceptions, Social Value, Connection, but not Authority. Applications and suggestions for further research using the Culturally-based Communication about Health, Eating, and Food (CHEF) Scale are proposed.

Polyphenols are important constituents of food products of plant origin. Fruits, vegetables, and beverages are the main sources of phenolic compounds in the human diet. These compounds are directly related to sensory characteristics of foods such as flavor, astringency and color. Polyphenols are extensively metabolized both in tissues and by the colonic microbiota. Normally, the circulating polyphenols are glucuronidated and/or sulphated and no free aglycones are found in plasma. The presence of phenolic compounds in the diet is beneficial to health due to their antioxidant, anti-inflammatory, and vasodilating properties. The health effects of polyphenols depend on the amount consumed and their bioavailability. Moreover, polyphenols are able to kill or inhibit the growth of microorganisms such as bacteria, fungi, or protozoans. Some dietary polyphenols may have significant effects on the colonic flora providing a type of prebiotic effect. The anti-nutrient properties of polyphenols are also discussed in this paper. The antioxidant, anti-inflammatory, vasodilating, and prebiotic properties of polyphenols make them potential functional foods.

Food marketing influences children's food preferences and consumption and is important to consider in the prevention of child obesity. In this paper, health messages in commercials during children's peak viewing times were analysed by examining how food is articulated in the health discourse. In total, 82 food commercials from 66h of television recordings of the most popular commercial channels with children in Sweden (TV3, TV4 and Channel 5) were analysed with discourse theoretical tools according to Laclau and Mouffe and with a focus on rhetoric. Physical, mental and social health aspects were present in 71% of the commercials. Three health discourse types; a medical (food as protection and treatment), a hedonic (food as feeling good) and a social discourse type (food as caring) were discerned. In relation to these, the heart symbol, lifestyle associations and nature/the natural were elements that could be interpreted in different ways. Moreover, foods carrying unhealthy associations were promoted in the health discourse and presented as especially healthy by offensive rhetoric. The analysis raises awareness of the prevailing health messages in food marketing. Children and parents should be encouraged to develop their critical thinking about television food advertising and how it may influence social norms and dietary practices.

A potential solution for weakened rural economies is the development of local food systems, which include affordable foods sources for consumers and economically feasible structures for producers. Local food systems are purported to promote sustainability, improve local economies, increase access to healthy foods, and improve the local diets. Four entrepreneurial food systems innovations that support local economies include farmers’ markets, community supported agriculture, farm to institution programs and food hubs. We review current literature to determine whether innovations for aggregation, processing, distribution and marketing in local food systems: 1) enable producers to make a living; 2) improve local economies; 3) provide local residents with greater access to affordable, healthy food; and 4) contribute to greater consumption of healthy food among residents. While there is some evidence for each, more transdisciplinary research is needed to determine whether entrepreneurial food systems innovations provide economic and public health benefits.

Two type of ready to eat supplementary food formulations were developed by roller drying based on wheat, soy protein concentrate, whey protein concentrate, and green gram flour and were fortified with vitamins and minerals to meet the one third of the Recommended daily allowance (RDA). The supplementary food formulations contained 20-21% protein, 370-390 kcal of energy and 2,300 μg of β-carotene per 100 g serving. The physico-chemical, functional and nutritional characteristics were evaluated. The chemical score indicated that sulphur containing amino acids were the first limiting in both the formulations. The calculated nutritional indices, essential amino acid index, biological value, nutritional index and C-PER were higher for formula II. Rat bioassay showed higher PER (2.3) for formula II compared to formula I (2.1). The bioaccessibility of iron was 23%. Sensory studies indicated that the products were acceptable with a shelf life of 1 year under normal storage condition. However, the formulations were nutritionally better than only cereal based supplementary food formulations available commercially. The product could be served in the form of porridge with water/milk or in the form of small laddu.

The Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico is a five-century institution that, besides the unique clinical role in the center of Milan, may rely on benefactor donations such as fields and farming houses not far from the city, for a total of 8500 ha, all managed by the "Sviluppo Ca' Granda' Foundation". Presently, the main products of these fields are represented by rice and cow's milk. During the latest years, farmers and managers have developed a model of sustainable food production, with great attention to the product quality based on compositional analysis and functional nutritional characteristics. This experience represents a new holistic model of food production and consumption, taking great care of both sustainability and health.

Marketing activities have attracted increased attention from scholars interested in racial disparities in obesity prevalence, as well as the prevalence of other preventable conditions. Although reducing the marketing of nutritionally poor foods to racial/ethnic communities would represent a significant step forward in eliminating racial disparities in health, we focus instead on a critical-related question. What is the relationship between marketing activities, food culture, and health disparities? This commentary posits that food culture shapes the demand for food and the meaning attached to particular foods, preparation styles, and eating practices, while marketing activities shape the overall environment in which food choices are made. We build on prior research that explores the socio-cultural context in which marketing efforts are perceived and interpreted. We discuss each element of the marketing mix to highlight the complex relationship between food culture, marketing activities, and health disparities.

Endothelial dysfunction is now well established as a pivotal early event in the development of major cardiovascular diseases including hypertension, atherosclerosis, and diabetes. The alteration of the endothelial function is often triggered by an imbalance between the endothelial formation of vasoprotective factors including nitric oxide (NO) and endothelium-dependent hyperpolarization, and an increased level of oxidative stress involving several prooxidant enzymes such as NADPH oxidase and, often also, the appearance of cyclooxygenase-derived vasoconstrictors. Preclinical studies have indicated that polyphenol-rich food and food-derived products such as grape-derived products, black and red berries, green and black teas and cocoa, and omega-3 fatty acids can trigger activating pathways in endothelial cells promoting an increased formation of nitric oxide and endothelium-dependent hyperpolarization. Moreover, intake of such food-derived products has been associated with the prevention and/or the improvement of an established endothelial dysfunction in several experimental models of cardiovascular diseases and in humans with cardiovascular diseases. This review will discuss both experimental and clinical evidences indicating that different types of food and natural products are able to promote endothelial and vascular health, as well as the underlying mechanisms.

For human beings, food is a critical contributor to physical well being, a major source of pleasure, worry and stress, a major occupant of waking time and, across the world, the single greatest category of expenditures. This is a first study of the way food functions in the minds and lives of people from four cultures. Adults and college students from Flemish Belgium, France, U.S.A. and Japan were surveyed with questions dealing with beliefs about the diet-health link, worry about food, the degree of consumption of foods modified to be "healthier" (e.g. reduced in salt or fat), the importance of food as a positive force in life, the tendency to associate foods with nutritional vs. culinary contexts, and satisfaction with the healthiness of one's own diet. In all domains except beliefs about the importance of diet for health, there are substantial country (and usually gender) differences. Generally, the group associating food most with health and least with pleasure is the Americans, and the group most food-pleasure-oriented and least food-health-oriented is the French. In all four countries, females, as opposed to males, show a pattern of attitudes that is more like the American pattern, and less like the French pattern. In either gender, French and Belgians tend to occupy the pleasure extreme, Americans the health extreme, with the Japanese in between. Ironically, the Americans, who do the most to alter their diet in the service of health, are the least likely to classify themselves as healthy eaters. We conclude that there are substantial cross-cultural differences in the extent to which food functions as a stressor vs. a pleasure. These differences may influence health and may partially account for national differences in rates of cardiovascular diseases (the "French paradox").

Executive function (EF) has long been considered to be a unitary, domain-general cognitive ability. However, recent research suggests differentiating “hot” affective and “cool” cognitive aspects of EF. Yet, findings regarding this two-factor construct are still inconsistent. In particular, the development of this factor structure remains unclear and data on school-aged children is lacking. Furthermore, studies linking EF and overweight or obesity suggest that EF contributes to the regulation of eating behavior. So far, however, the links between EF and eating behavior have rarely been investigated in children and non-clinical populations. First, we examined whether EF can be divided into hot and cool factors or whether they actually correspond to a unitary construct in middle childhood. Second, we examined how hot and cool EF are associated with different eating styles that put children at risk of becoming overweight during development. Hot and cool EF were assessed experimentally in a non-clinical population of 1657 elementary-school children (aged 6–11 years). The “food approach” behavior was rated mainly via parent questionnaires. Findings indicate that hot EF is distinguishable from cool EF. However, only cool EF seems to represent a coherent functional entity, whereas hot EF does not seem to be a homogenous construct. This was true for a younger and an older subgroup of children. Furthermore, different EF components were correlated with eating styles, such as responsiveness to food, desire to drink, and restrained eating in girls but not in boys. This shows that lower levels of EF are not only seen in clinical populations of obese patients but are already associated with food approach styles in a normal population of elementary school-aged girls. Although the direction of effect still has to be clarified, results point to the possibility that EF constitutes a risk factor for eating styles contributing to the development of overweight in the long

Climate/environmental change (C-E-C) is affecting human health and quality of life. Significant attention has been given to the impact of C-E-C on food supply, and food as a vehicle for exposure. However, C-E-C has been superimposed on prevalent malnutrition, infectious and non-communicable diseases. We discuss why nutrition is not synonymous with food and must be viewed as a biological variable that affects and is affected by both C-E-C as well as the current global health challenges. The nexus of C-E-C, food, nutrition and health must be considered in the development of safe and efficacious interventions. A case is presented for how the convergence of C-E-C, food/nutrition and health, presents an opportunity for more integrated approaches to achieve global health goals.

We investigated whether social presence cues encourage consumers to self-regulate and select healthier food products. In the first experiment, workers completed food choices in an e-commerce environment. After the activation of health-related goals, they saw a social presence cue and were asked to choose between healthy and unhealthy food options. The analyses revealed main effects of social presence and health goal activation on food choices. These effects were additive, such that the combination of social presence and health goals induced significantly healthier choices compared with the control group. The second experiment further examined social presence cues that were presented on a menu. The results showed significant effects on food choices and on the perceived self-regulatory success in dieting. These findings indicate that social presence cues could be employed to increase healthful eating and, furthermore, that it may be useful to co-activate multiple cues in health promotion messages.

The presence of a functional relationship between the ingestion of artificial food colors and an increase in the frequency and/or duration of selected behaviors that are representative of the hyperactive behavior syndrome was experimentally investigated. Two eight-year-old females, who had been on the Feingold K-P diet for a minimum of 11 months, were the subjects studied. The experimental design was a variation of the BAB design, with double-blind conditions. This design allowed an experimental analysis of the placebo phases as well as challenge phases. Data were obtained by trained observers on Out of Seat, On Task, and Physically Aggressive behaviors, as they occurred in the subjects' regular class setting. Results indicated (a) the existence of a functional relationship between the ingestion of artificial food colors and an increase in both the duration and frequency of hyperactive behaviors, (b) the absence of a placebo effect, and (c) differential sensitivity of the dependent variables to the challenge effects.

Objectives To identify the agriculture, food, and nutrition security interventions that facilitate sustainable food production and have a positive impact on health. Methods Systematic review methods were used to synthesize evidence from multiple systematic reviews and economic evaluations through a comprehensive search of 17 databases and 10 websites. The search employed a pre-defined protocol with clear inclusion criteria. Both grey and peer-reviewed literature published in English, Spanish, and Portuguese between 1 January 1997 and November 2013 were included. To classify as "sustainable," interventions needed to aim to positively impact at least two dimensions of the integrated framework for sustainable development and include measures of health impact. Results Fifteen systematic reviews and seven economic evaluations met the inclusion criteria. All interventions had some impact on health or on risk factors for health outcomes, except those related to genetically modified foods. Impact on health inequalities was rarely measured. All interventions with economic evaluations were very cost-effective, had cost savings, or net benefits. In addition to impacting health (inclusive social development), all interventions had the potential to impact on inclusive economic development, and some, on environmental sustainability, though these effects were rarely assessed. Conclusions What is needed now is careful implementation of interventions with expected positive health impacts but with concurrent, rigorous evaluation. Possible impact on health inequalities needs to be considered and measured by future primary studies and systematic reviews, as does impact of interventions on all dimensions of sustainable development.

American Samoa, one of the U.S.-affiliated Pacific Islands, has documented the highest prevalence of adults with obesity (75%) in the world. The nutritionally poor food and beverage environment of food retail venues has been suspected to be a contributing factor, although an evaluation of these venues in American Samoa has not been conducted. In January 2014, American Samoa established an Obesity Task Force to develop policies and strategies to combat obesity. To inform the efforts of the task force, the American Samoa Department of Health and CDC conducted a baseline assessment of the availability, pricing, and promotion of healthful foods at retail food venues. Previously validated food environment assessment tools were modified to incorporate American Samoa foods and administered in a geographically representative sample of 70 stores (nine grocery stores and 61 convenience stores) and 20 restaurants. In convenience stores, healthful items were not found as available as less healthful counterparts, and some healthful items were more expensive than their less healthful counterparts. For restaurants, 70% offered at least one healthful entrée, whereas only 30% had healthful side dishes, such as vegetables. Actions to promote healthy eating, such as providing calorie information, were rare among restaurants. Improving availability, affordability, and the promotion of healthful foods in American Samoa stores and restaurants could support healthy eating among American Samoa residents.

Introduction Living in a rural food desert has been linked to poor dietary habits. Understanding community perspectives about available resources and feasible solutions may inform strategies to improve food access in rural food deserts. The objective of our study was to identify resources and solutions to the food access problems of women in rural, southernmost Illinois. Methods Fourteen focus groups with women (n = 110 participants) in 4 age groups were conducted in a 7-county region as part of a community assessment focused on women’s health. We used content analysis with inductive and deductive approaches to explore food access barriers and facilitators. Results Similar to participants in previous studies, participants in our study reported insufficient local food sources, which they believe contributed to poor dietary habits, high food prices, and the need to travel for healthful food. Participants identified existing local activities and resources that help to increase access, such as home and community gardens, food pantries, and public transportation, as well as local solutions, such as improving nutrition education and public transportation options. Conclusion Multilevel and collaborative strategies and policies are needed to address food access barriers in rural communities. At the individual level, education may help residents navigate geographic and economic barriers. Community solutions include collaborative strategies to increase availability of healthful foods through traditional and nontraditional food sources. Policy change is needed to promote local agriculture and distribution of privately grown food. Understanding needs and strengths in rural communities will ensure responsive and effective strategies to improve the rural food environment. PMID:27126555

The concept of functional and novel foods undoubtedly bears great potential as an asset to human health. However, this very same quest for ever new bioactive ingredients calls for reliable and distinct risk assessment as they may be potentially hazardous to human health. Most of today’s methodologies still rely on decades old routines of animal trials and use of tumor-derived cell lines. Since such methodologies are not in line with the actual processes in the human body and with the 3R (replacement, reduction, refinement) concept, the results are often unreliable and misleading. Therefore, in this paper we propose the utilization of available untransformed small intestinal cell lines derived from human and pig tissue of non-tumor origin and describe several available cell models of the gut that offer a functional, close resemblance with the in vivo environment.

Companies in the food industry have high expectations for food products that meet the consumers' demand for a healthy life style. In this context Functional Food plays a specific role. These foods are not intended only to satisfy hunger and provide the necessary human nutrients, but also to prevent nutrition-related diseases and increase the physical and mental well-being of their consumer. Among participants in space science and missions, recognition of nutraceuticals and dietary supplements is growing for their potential in reducing health risks and to improve health quality and eating habits during long-term flights and missions. In 2008 the entire functional foods market was worth over an estimated US $80 billion, with the US holding a majority share in the nutraceuticals market (35%) followed byJapan (25%) and with the ever-growing European market, currently estimated at US$8 billion. India and China are the two major countries known for their production of traditional functional food products and nutraceuticals, but other South-East Asian countries and Gulf nations are developing potential markets.

Increasingly consumption of healthy foods is advised to improve population health. Reasons people give for choosing one food over another suggest that non-sensory features like health aspects are appreciated as of lower importance than taste. However, many food choices are made in the absence of the actual perception of a food’s sensory properties, and therefore highly rely on previous experiences of similar consumptions stored in memory. In this study we assessed the differential strength of food associations implicitly stored in memory, using an associative priming paradigm. Participants (N = 30) were exposed to a forced-choice picture-categorization task, in which the food or non-food target images were primed with either non-sensory or sensory related words. We observed a smaller N400 amplitude at the parietal electrodes when categorizing food as compared to non-food images. While this effect was enhanced by the presentation of a food-related word prime during food trials, the primes had no effect in the non-food trials. More specifically, we found that sensory associations are stronger implicitly represented in memory as compared to non-sensory associations. Thus, this study highlights the neuronal mechanisms underlying previous observations that sensory associations are important features of food memory, and therefore a primary motive in food choice.

Soil health as a factor of ensuring food security (the case of the Asia-Pacific Region) Food security is a complex issue of both international and national levels. The food embargo on imported products has defined the preservation and regeneration of soils as a priority task in ensuring the food security of the Russian Federation. Soils are a finite, non-renewable resource and their preservation is extremely important for the national food security. Food production is the major function of soils; production of high-quality foods, rich in nutrients, is possible only in healthy soils. Therefore, a healthy and fertile soil is the most important factor in ensuring the food security and improved subsistence. By 2050, in order to meet the demand for food, the global agricultural production has to increase by 60%, and almost by 100% in the developing countries. In many countries and subregions of the Asia-Pacific Region, the population growth rates outrun the rates of food production. The possibilities of incorporating new lands into agricultural activities and providing their irrigation are also limited. In the context of expanding cooperation with the Asia-Pacific neighbors, Russia can make its contribution into improving the food security of the region. Russia has vast territories that could be used for crops farming; a substantial part of these lands have not been farmed yet. Hence, in the Russian Far East, production of grain crops can be increased by incorporating the unused territories into agricultural activities. Therefore, the Russian Far East is a unique site for creating a crops farming territory. And the preservation and regeneration of soils will provide for the production growth and ensure the food security of Russia and the Asia-Pacific region.

The challenges of producing and distributing the food necessary to feed an anticipated 9 billion people in developed and developing societies by 2050 without destroying Earth's finite soil and water resources present extremely complex problems that lack simple solutions. The ability of modern societies to adequately address these and other food-related problems will require an educated workforce trained not only in traditional food safety, security, and public health, but also in other areas including food production, sustainable practices, and ecosystem health. To help address the need for such an educated workforce, a curricular framework was developed to assist those tasked with designing education and training for future food systems workers. One sentence summary: A curricular framework for education and training in food safety and security was developed that incorporates One Health concepts.

Food consumption patterns in Asia are rapidly changing. Urbanization and changing lifestyles have diminished the consumption of traditional meals based on cereals, vegetables and root crops. These changes are accompa-nied by an increasing prevalence of chronic diseases among Asian populations. ILSI Southeast Asia and CSIRO, Australia jointly organized the Symposium on Understanding and Influencing Food Behaviours for Health, focusing on the use of consumer science to improve food behaviour. The goals of the Symposium were to present an understanding of Asian consumers and their food choices, examine the use of consumer research to modify food choices towards better health, illustrate how health programs and food regulations can be utilized effectively to promote healthier choices, and identify knowledge gaps regarding the promotion of healthy food behaviour in Asian populations. There is no difference in taste perception among Asians, and Asian preference for certain tastes is determined by exposure and familiarity largely dictated by culture and its underlying values and beliefs. Cross-cultural validity of consumer science theories and tools derived from western populations need to be tested in Asia. Information on consumption levels and substitution behaviours for foods and food products, obtained using consumer research methods, can guide the development of food regulations and programs that will enable individuals to make healthier choices. Existing knowledge gaps include consumer research techniques appropriate for use in Asian settings, diet-health relationships from consumption of traditional Asian diets, and methods to address the increasing prevalence of over- and undernutrition within the same households in Asia.

To date, few studies have explored the neurochemical mechanisms supporting individual differences in food preference in humans. Here we investigate how dorsal striatal dopamine, as measured by the positron emission tomography (PET) tracer [18F]fluorometatyrosine (FMT), correlates with food-related decision-making, as well as body mass index (BMI) in 16 healthy-weight to moderately obese individuals. We find that lower PET FMT dopamine synthesis binding potential correlates with higher BMI, greater preference for perceived “healthy” foods, but also greater healthiness ratings for food items. These findings further substantiate the role of dorsal striatal dopamine in food-related behaviors and shed light on the complexity of individual differences in food preference. PMID:24806534

This study aimed to investigate gender differences in the fast food intake, health attitudes, and perceptions of fast food among adult Arab consumers aged 19 to 65 years in Kuwait. A total of 499 consumers (252 males, 247 females) were selected at convenience from three shopping malls in Kuwait City. The consumers were interviewed using a specially designed questionnaire. The findings revealed that men were more frequently consumed fast food than women (p < 0.001). Men were significantly more likely to consume "double" burgers (52%) than women (29.9%) (P < 0.001). The great majority of consumers (95%) considered fast food harmful to health. However, the consumers were continued to intake fast food (92%), indicating that health information on fast food not necessarly affects their consumption. Local foods were more likely to be considered fast food if eaten as a sandwich or without a disposal container. It can be concluded that fast food perceptions are influenced by gender, media and socio-cultural factors. Nutrition education programmes should focus on nutritive values of the foods rather than on their "fast food" classification.
In this article we analyze notions about healthy food and the perceptions of risks related to industrialized foodstuffs within a group of young and middle-aged females and males who belong to the middle class and live in the Metropolitan Area of Buenos Aires. Data come from eight focus groups that were carried out in 2013. The study shows that the participants of the focus group have incorporated scientific-nutritional knowledge into their conceptions of healthy food. However, few discuss the risks of industrialized food beyond the growing public attention regarding trans fats and salt content. Although organic foods are positively valued, participants object to their high cost and the location of their commercialization. We show how in their food practices, the participants of the focus groups weigh their concern about health against other priorities such as costs, convenience, aesthetics, pleasure and sociability.

It is presented a review of the guidelines implementation of the National Food and Nutrition Policy (PNAN) contextualizing the actions in the Brazilian Unified Health System (SUS) scenario. At ten years of its publication, PNAN faces challenges both to expand and qualify the shares of food and nutrition on health. It is challenging to stand as interlocutor and legitimate representative of the area of health, political and institutional context of food security and nutrition. Issues related to the articulation of PNAN and future National Policy on Food and Nutrition Security will be analyzed to demonstrate the convergence of agendas among the priorities for the guarantee of the SAN. The authors identify the potential of this field of action, from the current institutional setting, and the need for comprehensive solutions that address the complexity of food and nutrition in health.

Residual styrene present in polystyrene food packaging may migrate into food at low levels. To assure safe use, safe exposure levels are derived for consumers potentially exposed via food using No/Low Adverse Effect Levels from animal and human studies and assessment factors proposed by European organisations (EFSA, ECHA, ECETOC). Ototoxicity and developmental toxicity in rats and human ototoxicity and effects on colour discrimination have been identified as the most relevant toxicological properties for styrene health assessments. Safe exposure levels derived from animal studies with assessment factors of EFSA and ECHA were expectedly much lower than those using the ECETOC approach. Comparable safe exposure levels were obtained from human data with all sets of assessment factors while ototoxicity in rats led to major differences. The safe exposure levels finally selected based on criteria of science and health protection converged to the range of 90-120 mg/person/d. Assuming a consumption of 1 kg food/d for an adult, this translates to 90 mg styrene migration into 1 kg food as safe for consumers. This assessment supports a health based Specific Migration Limit of 90 ppm, a value somewhat higher than the current overall migration limit of 60 ppm in the European Union.

Objectives. We investigated the risk of household food insecurity and reported fair or poor health among very young children who were US citizens and whose mothers were immigrants compared with those whose mothers had been born in the United States. Methods. Data were obtained from 19 275 mothers (7216 of whom were immigrants) who were interviewed in hospital-based settings between 1998 and 2005 as part of the Children's Sentinel Nutrition Assessment Program. We examined whether food insecurity mediated the association between immigrant status and child health in relation to length of stay in the United States. Results. The risk of fair or poor health was higher among children of recent immigrants than among children of US-born mothers (odds ratio [OR] = 1.26; 95% confidence interval [CI] = 1.02, 1.55; P < .03). Immigrant households were at higher risk of food insecurity than were households with US-born mothers. Newly arrived immigrants were at the highest risk of food insecurity (OR = 2.45; 95% CI = 2.16, 2.77; P < .001). Overall, household food insecurity increased the risk of fair or poor child health (OR = 1.74; 95% CI = 1.57, 1.93; P < .001) and mediated the association between immigrant status and poor child health. Conclusions. Children of immigrant mothers are at increased risk of fair or poor health and household food insecurity. Policy interventions addressing food insecurity in immigrant households may promote child health. PMID:19106417

The Bowman-Birk inhibitor (BBI) is a small water-soluble protein present in soybean and almost all monocotyledonous and dicotyledonous seeds. The molecular size of BBI ranges from 1,513 Da to about 20,000 Da. BBI is to seeds what alpha(1)-antitrypsin is to humans. Soy-based food products rich in BBI include soybean grits, soymilk, oilcake, soybean isolate, and soybean protein concentrate. BBI is stable within the pH range encountered in most foods, can withstand boiling water temperature for 10 min, resistant to the pH range and proteolytic enzymes of the gastrointestinal tract, bioavailable, and not allergenic. BBI reduces the proteolytic activities of trypsin, chymotrypsin, elastase, cathepsin G, and chymase, serine protease-dependent matrix metalloproteinases, urokinase protein activator, mitogen activated protein kinase, and PI3 kinase, and upregulates connexin 43 (Cx43) expression. Several studies have demonstrated the efficacy of BBI against tumor cells in vitro, animal models, and human phase IIa clinical trials. FDA considers BBI as a drug. In 1999, FDA allowed a health claim on food labels stating that a daily diet containing 25 grams of soy protein, also low in saturated fat and cholesterol, may reduce the risk of heart disease [corrected] This review highlights the biochemical and functional food properties of the Bowman-Birk inhibitor.

Emergency foodbanks have become an increasingly prominent and controversial feature of austerity in Europe and the USA. In the UK, foodbanks have been called a 'public health emergency'. Despite this, there has been no UK research examining the health of foodbank users. Through an ethnographic study, this paper is the first to explore the health and health perceptions of foodbank users via a case study of Stockton-on-Tees in the North East of England, UK during a period of welfare reform and austerity. Participant observation, field notes and interviews with foodbank users and volunteers were conducted over a seventeen month period (November 2013 to March 2015) inside a Trussell Trust foodbank. Foodbank users were almost exclusively of working age, both men and women, with and without dependent children. All were on very low incomes - from welfare benefits or insecure, poorly paid employment. Many had pre-existing health problems which were exacerbated by their poverty and food insecurity. The latter meant although foodbank users were well aware of the importance and constitution of a healthy diet, they were usually unable to achieve this for financial reasons - constantly having to negotiate their food insecurity. More typically they had to access poor quality, readily available, filling, processed foods. Foodbank users are facing the everyday reality of health inequalities at a time of ongoing austerity in the UK.
Background Inadequate access to healthful foods has been identified as a significant barrier to healthful dietary behaviors among individuals who live in low-income communities. The purpose of this study was to gather low-income community members’ opinions about their food purchasing choices and their perceptions of the most effective ways to increase access to healthful foods in their communities. Methods Spanish and English focus groups were conducted in low-income, ethnically-diverse communities. Participants were asked about their knowledge, factors influencing their food purchasing decisions, and their perceptions regarding solutions to increase access to healthful foods. Results A total of 148 people participated in 13 focus groups. The majority of participants were female and ethnically diverse (63% Hispanic, 17% African American, 16% Caucasian, and 4% “other”). More than 75% of the participants reported making less than $1999 USD per month. Participants reported high levels of knowledge and preference for healthful foods. The most important barriers influencing healthful shopping behaviors included high price of healthful food, inadequate geographical access to healthful food, poor quality of available healthful food, and lack of overall quality of the proximate retail stores. Suggested solutions to inadequate access included placement of new chain supermarkets in their communities. Strategies implemented in convenience stores were not seen as effective. Farmers’ markets, with specific stipulations, and community gardens were regarded as beneficial supplementary solutions. Conclusion The results from the focus groups provide important input from a needs assessment perspective from the community, identify gaps in access, and offer potential effective solutions to provide direction for the future.

A global economic and financial crisis is engulfing the developing world, coming on top of high food and fuel prices. This paper assesses the impact of the crises on food consumption, nutrition, and health. Several methods were applied, including risk analysis using the cost of the food basket, assessment surveys, simulations, regression analysis using a food consumption score (FCS), reflecting diet frequency and diversity, and a review of the impact of such dietary changes on nutritional status and health. The cost of the food basket increased in several countries, forcing households to reduce quality and quantity of food consumed. The FCS, which is a measure of diet diversity, is negatively correlated with food prices. Simulations show that energy consumption declined during 2006-2010 in nearly all developing regions, resulting potentially in an additional 457 million people (of 4.5 billion) at risk of being hungry and many more unable to afford the dietary quality required to perform, develop, and grow well. As a result of the crises, large numbers of vulnerable households have reduced the quality and quantity of foods they consume and are at risk of increased malnutrition. Population groups most affected are those with the highest requirements, including young children, pregnant and lactating women, and the chronically ill (particularly people with HIV/AIDS and tuberculosis). Because undernutrition during the first 2 y of life has life-long consequences, even short-term price rises will have long-term effects. Thus, measures to mitigate the impact of the crises are urgently required.

Economic growth inevitably influences the food chain. Growing demand with changes in lifestyle and health consciousness encourage use of packaged and pre-prepared foods. The needs of environmental protection from waste generated are largely overlooked, and a lack of knowledge about the impact on the environment and its health effects constitute food security/safety problems. Food production and waste generation directly affect resource (i.e., energy and water) consumption and often contaminate the environment. More pressure on food production has inculcated the use of pesticides, herbicides, antibiotics and chemical fertilizers which add to current global pollution. At least half of food grown is discarded before and after it reaches consumers. It is estimated that one third to half of landfill waste comes from the food sector. This landfill releases green house gases (GHG) as well as leachate which worsen soil and water quality and safety. Pharmaceutical and chemical contaminations from residential, industrial and agricultural sources make their way into nearby water and soil and can eventually affect our food systems. Phthalates, PFOA, BPA, commonly used in plastics and personal care products, are found in unacceptable concentrations in Taiwanese waters. They, too, contribute to food contamination and long-term health risk. Existing waste management strategies warrant more stringent norms for waste reduction at source. Awareness through education could reduce food waste and its consequences. This review encompasses impacts of food production systems on the environment, pollution which results from food waste, costs and economic advantages in food waste management, and health consequences of waste.

Objective To quantify the prevalence of advertising for foods and beverages potentially detrimental to dental health on UK television watched by children.Design Content analysis of pre-recorded television advertisements (adverts).Materials and methods Three hundred and fifty-two hours of television were recorded (one weekday and one weekend day, 6 am - 10 pm) from the main commercial channel (ITV1). All adverts were coded using pre-defined criteria.Setting UK television recorded between January and December 2012.Results Of 9,151 adverts, foods and beverages were the second most commonly advertised products (16.7%; n = 1,532). Nearly two-thirds of food adverts were for items that are potentially harmful to dental health (61%; n = 934). Of these, 96.6% were cariogenic and 11% were acidogenic foods. During peak children's viewing hours, the proportion of foods that are potentially harmful to dental health was significantly higher than for non-harmful foods (65.9% vs. 34.1%; p = 0.011). Adverts for foods potentially harmful to dental health were rare around children's programmes, but significantly more frequent during other programmes watched by children (p <0.001).Conclusion UK children are exposed to a particularly high proportion of advertisements for foods that are potentially detrimental to their dental health during their peak viewing hours and around the programmes they watch the most.

Previous research has found that while self-regulation is a resource that can be depleted, enhanced motivation to do so can help people successfully self-regulate. The aim of this research was to determine whether activating health goals-either via laboratory priming techniques or via advertisements-can help people regulate food intake later in the day, when self-regulation resources are typically depleted. In two experimental studies, participants completed goal activation tasks in the morning or in the afternoon while they had a snack food (M&M's candies) available for consumption. In study 1, 121 participants viewed television shows with either healthy food ads, indulgent food ads, or non-food ads embedded within the program. In study 2, 149 participants completed a supraliminal but nonconscious goal priming exercise, in which they searched for health, indulgence, or control words in a puzzle. In both studies, activation of health goals led to decreased consumption of the snack food in the afternoon. In contrast, activation of health goals did not change consumption in the morning, when self-regulatory resources are typically high, due to replenishment after rest. These results suggest that activating health goals-either via classic laboratory goal-priming paradigms or via "real world primes," such as ads for healthy foods-helps people to overcome failures in curbing food consumption due to depleted self-regulatory resources later in the day.

Fermentation has had a long history in human food production and consumption. Fermented foods and beverages can comprise anywhere between 5-40% of the human diet in some populations. Not only is this process beneficial for extending shelf-life for foods and beverages, but also fermentation can enhance nutritional properties in a safe and effective manner. In many developed countries, traditional methods are now replaced with specific technologies for production of fermented foods, and an emerging industrial practice allows for higher quality standardization of food products in the market place. Due to changes in fermentation processes and the increased consumption of these products, a detailed review of recent patents involving fermented foods and beverages and their impact on health is warranted. Fermented food products that can enhance nutrition, improve health, and prevent disease on a global level will require consistent fermentation methods, evaluation of nutritional compositions, and food safety testing. This review is intended to guide the development of fermented foods for enhanced human health benefits and suggests the need for multidisciplinary collaborations and structural analysis across the fields of food science, microbiology, human nutrition, and biomedical sciences.

This research involved a diagnosis of the educational actions and organic food of the Taste and Awareness Project (Projeto Sabor e Saber, PSS) in a state school in Florianopolis, Brazil. Based on a qualitative approach, a semi-structured interview, documentation analysis and focal groups were used for data collection. The participants were managers of School Meals; a school head and a group of students and teachers representing the school. The results indicated that the PSS has advanced in its objectives, combining the introduction of organic foods with educational actions involving food, health, nutrition and the environment but with no evaluations of this process; organic food is present in school meals, although there is no record of educational actions; food is a subject on the Science course; the themes of food, health and nutrition in the school environment come up without planning; the evaluation of students regarding the food is positive, but no reference was made to organic foods. It was concluded that the use of organic food, is still not an element of the pedagogical project. However, the research contributed to the teachers, on the need to develop educational actions in health, organic foods and nutrition, within the school community.

The growing momentum of several common life-style diseases such as myocardial infarction, cardiovascular disorders, stroke, hypertension, diabetes, and atherosclerosis has become a serious global concern. Recent developments in the field of proteomics offering promising solutions to solving such health problems stimulates the uses of biopeptides as one of the therapeutic agents to alleviate disease-related risk factors. Functional peptides are typically produced from protein via enzymatic hydrolysis under in vitro or in vivo conditions using different kinds of proteolytic enzymes. An array of biological activities, including antioxidative, antihypertensive, antidiabetic and immunomodulating has been ascribed to different types of biopeptides derived from various food sources. In fact, biopeptides are nutritionally and functionally important for regulating some physiological functions in the body; however, these are yet to be extensively addressed with regard to their production through advance strategies, mechanisms of action and multiple biological functionalities. This review mainly focuses on recent biotechnological advances that are being made in the field of production in addition to covering the mode of action and biological activities, medicinal health functions and therapeutic applications of biopeptides. State-of-the-art strategies that can ameliorate the efficacy, bioavailability, and functionality of biopeptides along with their future prospects are likewise discussed.

Whey proteins are well known for their high nutritional value and versatile functional properties in food products. Estimates of the worldwide production of whey indicate that about 700,000 tonnes of true whey proteins are available as valuable food ingredients. Nutritional and functional characteristics of whey proteins are related to the structure and biological functions of these proteins. During recent decades, interest has grown in the nutritional efficacy of whey proteins in infant formula and in dietetic and health foods, using either native or predigested proteins. This paper focuses attention on the differences and similarities in composition of human and bovine milks with reference to infant formula. More desirable milk protein composition for consumption by humans is obtained by the addition of lactoferrin and more specific fractionations of proteins from bovine milk. Optimization of heating processes is important to minimize the destruction of milk components during fractionation and preservation processes. Some functional characteristics of whey proteins are discussed in relation to their properties for application in food products. Information obtained from functional characterization tests in model systems is more suitable to explain retroactively protein behavior in complex food systems than to predict functionality.

Household food insufficiency is a significant problem in the United States, and has been associated with poor outcomes on mental health indicators among low-income women. However, it is difficult to disentangle the mental health consequences of household food insufficiency from poverty and other shared risk factors. Drawing on theories of the social production of health and disease, research evidence linking food insufficiency with poor mental health, and high rates of food insufficiency among welfare recipients, we examined whether a change in household food insufficiency is associated with a change in women's self-reported mental health in a sample of current and recent welfare recipients over a 3-year period of time, controlling for common risk factors. Data were obtained from a prospective survey of women who were welfare recipients in an urban Michigan county in February 1997 (n=753). We estimated fixed effect models for changes in mental health status that make use of information on household food insufficiency gathered in the fall of 1997, 1998, and 1999. The relationship between household food insufficiency and respondents' meeting the diagnostic screening criteria for major depression remained highly significant even when controlling for factors known to confer increased risk of depression and time invariant unobserved heterogeneity. These findings add to growing evidence that household food insufficiency has potentially serious consequences for low-income women's mental health. If confirmed by further research, they suggest that the public health burden of depression in welfare recipients and other low-income women could be reduced by policy-level interventions to reduce their exposure to household food insufficiency.

Environmental pollution and food safety are two of the most important issues of our time. Soil and water pollution, in particular, have historically impacted on food safety which represents an important threat to human health. Nowhere has that situation been more complex and challenging than in China, where a combination of pollution and an increasing food safety risk have affected a large part of the population. Water scarcity, pesticide over-application, and chemical pollutants are considered to be the most important factors impacting on food safety in China. Inadequate quantity and quality of surface water resources in China have led to the long-term use of waste-water irrigation to fulfill the water requirements for agricultural production. In some regions this has caused serious agricultural land and food pollution, especially for heavy metals. It is important, therefore, that issues threatening food safety such as combined pesticide residues and heavy metal pollution are addressed to reduce risks to human health. The increasing negative effects on food safety from water and soil pollution have put more people at risk of carcinogenic diseases, potentially contributing to 'cancer villages' which appear to correlate strongly with the main food producing areas. Currently in China, food safety policies are not integrated with soil and water pollution management policies. Here, a comprehensive map of both soil and water pollution threats to food safety in China is presented and integrated policies addressing soil and water pollution for achieving food safety are suggested to provide a holistic approach.

The consumption and commercial exploitation of Allanblackia (Clusiaceae) seed oils is of current interest. The favorable physicochemical characteristics of Allanblackia oil (solid at room temperature; high stearic acid content) lend food products that contain it (i.e., vegetable-based dairy products, ice cream, spreads) health advantages over others that contain higher levels of lauric, myristic, and/or palmitic acids, which can increase blood cholesterol levels. Such considerations are important for individuals prone to cardiovascular disease or with hypercholesterolemia. Domestication projects of several Allanblackia species in tropical Africa are underway, but wildcrafting of fruits to meet the seed demand still occurs. Proper species authentication is important, since only authenticated oil can be deemed safe for human consumption. The chemical constituency of Allanblackia seed oils, and potential roles of these phytochemicals in preventive strategies (e.g., as part of a healthy diet) and as pharmacological agents used to treat chronic disease were examined in this review. The primary and secondary metabolite constituency of the seed oils of nearly all Allanblackia species is still poorly known. The presence, identity, and quantity of potentially bioactive secondary metabolites in the seed oils, and pharmacological testing of isolated compounds were identified as important directions for future research.

For a number of reasons, meat products are an exceptionally adequate means for introducing different bioactive compounds into the diet without modifying eating habits. In recent years, there has been a notable development of meat products designed as potentially functional foods. Within the framework of the functional food, this article provides a general view of the reasons that motivate and justify their formulation, with special emphasis on: a) aspects to be considered in their design in order to be able to make nutrition claims and statements concerning their health-promoting properties; b) the strategies employed to optimize the presence of functional ingredients, favoring the presence of beneficial bioactive compounds and limiting others with negative consequences for our health, and c) the procedures for demonstrating a relationship between the consumption of potentially functional meat products with beneficial effects on health and the way in which these studies are reflected in the literature.

Species diversity is changing globally and locally, but the complexity of ecological communities hampers a general understanding of the consequences of animal species loss on ecosystem functioning. High animal diversity increases complementarity of herbivores but also increases feeding rates within the consumer guild. Depending on the balance of these counteracting mechanisms, species-rich animal communities may put plants under top-down control or may release them from grazing pressure. Using a dynamic food-web model with body-mass constraints, we simulate ecosystem functions of 20,000 communities of varying animal diversity. We show that diverse animal communities accumulate more biomass and are more exploitative on plants, despite their higher rates of intra-guild predation. However, they do not reduce plant biomass because the communities are composed of larger, and thus energetically more efficient, plant and animal species. This plasticity of community body-size structure reconciles the debate on the consequences of animal species loss for primary productivity. PMID:27703157

Targeted marketing of high-calorie foods and beverages to ethnic minority populations, relative to more healthful foods, may contribute to ethnic disparities in obesity and other diet-related chronic conditions. We conducted a systematic review of studies published in June 1992 through 2006 (n = 20) that permitted comparison of food and beverage marketing to African Americans versus Whites and others. Eight studies reported on product promotions, 11 on retail food outlet locations, and 3 on food prices. Although the evidence base has limitations, studies indicated that African Americans are consistently exposed to food promotion and distribution patterns with relatively greater potential adverse health effects than are Whites. The limited evidence on price disparities was inconclusive.

The Mediterranean diet (MD) is considered one of the healthiest dietary models. Many of the characteristic components of the MD have functional features with positive effects on health and wellness. The MD adherence, calculated through various computational scores, can lead to a reduction of the incidence of major diseases (e.g., cancers, metabolic and cardiovascular syndromes, neurodegenerative diseases, type 2 diabetes and allergy). Furthermore, eating habits are the main significant determinants of the microbial multiplicity of the gut, and dietary components influence both microbial populations and their metabolic activities from the early stages of life. For this purpose, we present a study proposal relying on the generation of individual gut microbiota maps from MD-aware children/adolescents. The maps, based on meta-omics approaches, may be considered as new tools, acting as a systems biology-based proof of evidence to evaluate MD effects on gut microbiota homeostasis. Data integration of food metabotypes and gut microbiota “enterotypes” may allow one to interpret MD adherence and its effects on health in a new way, employable for the design of targeted diets and nutraceutical interventions in childcare and clinical management of food-related diseases, whose onset has been significantly shifted early in life.

Atherosclerosis, one of the main pathologic entities considered epidemic and a worldwide public health problem, is currently under constant review as regards its basic determining mechanisms and therapeutic possibilities. In this regard, all patients afflicted with the disease exhibit mitochondrial dysfunction, oxidative stress and inflammation. Interestingly, nitric oxide - a known vasoactive messenger gas - has been closely related to the inflammatory, oxidative and mitochondrial dysfunctional process that characterizes atherosclerosis. In addition, it has recently been demonstrated that alterations in the bioavailability of nitric oxide would induce the expression of heat shock proteins. This agrees with the use of functional foods as a strategy to prevent both vascular aging and the development of atherosclerosis. Finally, a greater knowledge regarding the mechanisms implied in the development of atherosclerosis will enable proposing new and possible hygiene, health and therapeutic interventions.

Background Prison is a major “place” for drug users in the US, yet remarkably little is known about the lived experience of incarceration. More information about prison life is needed to improve health outcomes for incarcerated and formerly incarcerated people. Methods Thirty (30) formerly incarcerated women were interviewed about prison food. All interviews were digitally recorded and transcribed. Qualitative data analysis software was used to code and organize the data using thematic analysis. Results As described in these participants’ narratives, prison food systems contributed to the construction of boundaries that distinguished the prison place from places and life outside the institution's walls. Participants also described boundaries within the prison that resulted in a patchwork of interior places, each with their own unique structure, meaning, and food system. These places, constructed by physical location, movement, and power, or lack thereof, included various micro-geographies that further defined women's individual prison experience. The boundaries that separated these places were not fixed: Women shifted and diminished internal and external borders by resisting food policies and reproducing their outside lives inside. Conclusion These findings call for public policy officials and prison administrators to reexamine the prison place in order to facilitate healthier eating behaviors and lay the groundwork for more positive communication between inmates and correctional staff and administration. More research is needed to measure how these types of changes to the prison food environment impact nutritional, mental health, substance abuse, and criminal justice outcomes. PMID:24412007

In the article there is presented the experience of justification of hygienic standards of food safety with the use of criteria for the risk for population health. Health risk assessment under the impact of tetracyclines with food showed that the content of residual amounts of these antibiotics at the level of 10 mg/kg (permissible residual tetracycline accepted in Customs Union Member Countries (CUMC) will not increase the risk to public health, including the most sensitive groups of the population. The assessment ofthe health risk associated with the receipt of ractopamine with food, showed that eating foods containing ractopamine at ADI level (0-1 mg/kg body weight), and even at the limit of quantification levels in meat products, is inadmissible because of unacceptable risk of functional disorders and diseases of the cardiovascular system. The results of the substantiation of the permissible levels of nitrates content in crop production showed that at the level of exposure according to hygienic standards established in the CUMC as at the recommended and actual consumption levels of products ofplant origin, the health risk as carcinogenic and non-carcinogenic, does not exceed acceptable levels. The results of the assessment of the risk associated with the permissible levels of L. monocytogenes in certain food groups showed that an exposure level of hygienic standards established in the CUMC, standards of Codex Alimentarius Commission and EU documents (before release to the market by the manufacturer) the health risk does not exceed the maximum permissible level of the appearance of serious diseases. Adoption of standards of Codex Alimentarius Commission and the EU (for handling products in the market) is not acceptable because it can lead to an unacceptable risk of listeriosis for the population of the Russian Federation as a whole, and for the most sensitive groups.

Due to new, previously unknown, properties attributed to engineered nanoparticles many new products are introduced in the agro-food area. Nanotechnologies cover many aspects, such as disease treatment, food security, new materials for pathogen detection, packaging materials and delivery systems. As with most new and evolving technologies, potential benefits are emphasized, while little is known on safety of the application of nanotechnologies in the agro-food sector. This review gives an overview of scientific issues that need to be addressed with priority in order to improve the risk assessment for nanoparticles in food. The following research topics are considered to contribute pivotally to risk assessment of nanotechnologies and nanoparticles in food products. Set a definition for NPs to facilitate regulatory discussions, prioritization of research and exchange of study results. Develop analytical tools for the characterization of nanoparticles in complex biological matrices like food. Establish relevant dose metrics for nanoparticles used for both interpretation of scientific studies as well as regulatory frameworks. Search for deviant behavior (kinetics) and novel effects (toxicity) of nanoparticles and assess the validity of currently used test systems following oral exposure. Estimate the consumer exposure to nanoparticles.

The objective of this study was to examine food insecurity among psychiatric patients and as a concern for mental health practitioners. Food security and psychological distress were measured among 113 patients hospitalized in a psychiatric emergency unit. Of 113 respondents 67 (59.3%) enjoyed food security and 46 (40.7%) lacked food security. Food insecure respondents showed a higher level of psychological distress than food secure respondents. A large proportion of in-patients may be suffering food insecurity which is negatively associated with their psychological well being. Mental health practitioners need to be aware of the potential association of food insecurity and mental distress among psychiatric patients.

This qualitative study explored the understandings of body size, food and eating, and health held by Filipino women living in Canada. Women (n = 11) aged 19 to 30 years old who were born in the Philippines and living in British Columbia participated in individual interviews where they discussed their beliefs and practices relating to their body, food, and health. Informants' comments reflected contrasting "Canadian" and "Filipino" meanings. Canadian beliefs emphasized the desirability of thinness, "watching" intake of fat, rice, and junk food, and minimizing disease risk. Filipino beliefs valued fatness, "just eating" fat and rice, and maximizing disease resistance. While most informants appeared to have adopted the Canadian values, Filipino beliefs continued to be of some significance in their lives. These findings demonstrate the socially constructed nature of health beliefs and illustrate how members of a minority ethnic group negotiate among conflicting cultural beliefs about body size, food and health.

This study applies the concepts of health halos and unhealthy = tasty intuition to examine how the different health and nutrition-related (HNR) appeal types interact with different food product types compared with taste claims. The experiment investigated the impact of benefit-seeking and risk-avoidance HNR appeals compared with that of taste appeals on different food types. The authors found that although respondents evaluated food ads with the two HNR appeals as less risky/more beneficial and healthier than food ads with a taste claim, the respondents showed better ad-related evaluations on the HNR appeals for perceivably healthy food and on taste appeal for perceivably unhealthy food. The findings provide several theoretical and practical implications for health food marketing and public health policy.

However, little is known about pre-service teachers' preparation in this area. This article addresses this gap by providing a case study of one approach to food education, which was purposefully…
A written questionnaire was used to assess the opportunities and challenges for food safety education in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). The sample included directors and health professionals with nutrition counseling responsibilities in 79 WIC clinics in a midwestern state. Seventy-two percent of the clinics participated in the study. Data analysis included descriptive statistics, chi(2) analysis, and Cronbach's alpha. Seventy-two percent reported offering food safety advice to 20% or more of their clients daily. Ninety percent identified the food-safety knowledge of their WIC clients to be fair to very poor. The need for food safety handouts, targeted for WIC clients, was identified by 27% of the respondents. WIC professionals are promoting safe food handling among a high-risk population group. Expansion of current food-safety education efforts with WIC clients is encouraged with emphasis on methods to effectively overcome barriers to safe food handling.
The EC Quality of Life Programme (QoL), Key Action 1--Food, Nutrition & Health aims at providing a healthy, safe, and high-quality food supply leading to reinforced consumer's confidence in the safety of the European food. Key Action 1 is currently supporting several European projects investigating analytical methods for food control including sensors, risk analysis, and food safety standardisation. Their objectives range from the development and validation of prevention strategies for mycotoxin formation via the development of a communication platform for Genetically Modified Organisms (GMO), validation and standardisation of diagnostic Polymerase Chain Reaction (PCR) for food-borne pathogens, up to the evaluation of the potential cancer-preventing activity of pro- and pre-biotic ("SYNBIOTIC") combinations in human volunteers. This paper also informs on future research needs in food safety.
Public health practitioners interested in supporting consumers to make healthy, sustainable food choices need to understand consumer motivations to reduce food system risk. Increasingly food technologies that have enhanced access to food supply are being recognised as also impacting on the sustainability of the food system. This study explored the actions taken by Australian participants in response to their concerns about perceived food related threats to health and environment. Variance in willingness to act is analysed within the context of environmental and ecological citizenship, and a continuum describes the range of positions held. From the outset some participants self-identified as environmentally concerned and proactive, while others indicated a secondary interest in the environment. The catalyst for action for the majority was the priority of individual health and such self-interest can be a powerful motivator for change. Others related health to the environment and described efforts to minimise individual impact. Equally important for action to occur is being at a stage in life where other demands do not compete for the time and energy necessary to take citizenship actions. These results provide insight into the support that public health practitioners can offer to consumers who wish to make sustainable food choices.

This article discusses the establishment of inter-sector action between health and food and nutritional security in Brazil from 2003 to 2010, when this issue was launched as a priority on the government's agenda. A qualitative study was developed according to constructivist epistemology, using key-informant interviews in the field's nationwide social oversight body. Advances and challenges in this process are addressed as analytical categories. The National Food and Nutrition Policy (PNAN) was mentioned as the link between the two fields, decentralized through a network with activity in the states and municipalities. However, the study found political, institutional, and operational obstacles to the effective implementation of the PNAN in the Brazilian Unified National Health System and consequently to a contribution to the advancement of Health and Food and Nutritional Security in the country. The predominance of the biomedical, curative, and high-complexity model was cited as the principal impediment, while health promotion policies like the PNAN were assigned secondary priority.

Over the past decade, the liability risks associated with food and beverage product marketing have increased significantly, particularly with respect to nutrition and health-related product benefit claims. FDA and FTC enforcement priorities appear to have contributed to the increasing liability trends that are associated with these nutrition and health-related claims. This article examines key enforcement and litigation developments involving conventional food and beverage product marketing claims during the first 18 months of President Obama's administration: Part I considers FDA enforcement priorities and recent warning letters; Part II considers FTC enforcement priorities, warning letters, and consent orders; and Part III considers the relationship between FDA and FTC enforcement priorities and recent false advertising cases brought by private parties challenging nutrition and health-related marketing claims for food and beverage products. The article makes recommendations concerning ways in which food and beverage companies can help minimize liability risks associated with health-related marketing claims. In addition, the article suggests that federal policy reforms may be required to counter the perverse chilling effects current food liability trends appear to be having on health-related marketing claims for food and beverage products, and proposes a number of specific reforms that would help encourage the responsible use of well-substantiated marketing claims that can help foster healthy dietary practices. In view of the obesity prevention and other diet-related public health priorities of the Obama administration, the article suggests that this is an opportune time to address the apparent chilling effects increasing food liability risks are having on nutrition and health-related marketing claims for healthy food and beverage products, and potential adverse consequences for public health.

Introduction: The US Centers for Disease Control and Prevention (USDHHS-CDC 1996) revealed that the outbreaks of food borne diseases include inadequate cooking, heating, or re-heating of foods consumption of food from unsafe sources, cooling food inappropriately and allowing too much of a time lapse. As we all know that the food handlers have been working in various types of community kitchen and their health status can affect the status of food hygiene which can lead to contamination of foods attributing to acute gastroenteritis and food poisoning in various subgroups of the population e.g., medical/dental/nursing students. The background characteristics of these food handlers may have important role to affect health status of these handlers. Methods: The indexed study was carried out among the food handlers working in the food establishments the 5 teaching hospitals of Bareilly city in U.P. India during one year i.e., from August 2013 to July 2014. The survey method using schedule was conducted to get information about the background characteristics and food handlers and each food handler was examined clinically for assessing health status. Chi-Square test was used as test of significance and regression analysis was also done to nullifying the effect of confounders. Results: The health status of the mess workers was found to be significantly associated with use of gloves, hand washing after toilet and hand washing before cooking and serving food. Conclusion: The rationale of this study was that though many studies have been carried out to show the health status of the food handlers and their background characteristics, no study has highlighted the association of these background characteristics and personal hygiene practices with the health status of food handlers.

This paper presents a summary of Pohnpei, Federated States Micronesia's involvement in a global health study focused on documenting traditional food systems in different parts of the world and providing evidence that local resources are critical for food security, nutrition and health. The Pohnpei study was based in Mand Community, Madolenihmw. The study found that there was a great diversity of foods locally available (381 food items documented), but these were underused. Overweight, obesity, diabetes, and vitamin A deficiency were identified as serious problems. Interventions included community meetings, school activities, and agriculture workshops, cooking classes, charcoal oven development, weight loss and planting competitions, poster campaigns and other relevant mass media. Significant dietary improvements were achieved following the intervention efforts, as well as positive changes in attitude towards local food including: decrease in average daily rice consumption from 846 g/person in 2005 to 544 g/person in 2007 (p = 0.0002); increase in provitamin A carotenoid intake from 227 microg/person in 2005 to 475 microg/person in 2007 (p = 0.02); increased frequency of consumption of local banana (53%), giant swamp taro (476%), local vegetables (130%); and increased dietary diversity (4.8 local food groups consumed in 2005 to 5.5 in 2007). Another positive outcome in Pohnpei was the popularization of the slogan "Let's Go Local."

Objective Food insecurity may be a modifiable and independent risk factor for worse control of medical conditions, but it has not been explored among veterans. We determined the prevalence of, and factors independently associated with, food insecurity among veterans in the Veterans Aging Cohort Study (VACS). Methods Using data from VACS from 2002–2008, we determined the prevalence of food insecurity among veterans who have accessed health care in the Veterans Health Administration (VA) as defined by “concern about having enough food for you or your family in the past month.” We used multivariable logistic regression to determine factors independently associated with food insecurity and tests of trend to measure the association between food insecurity and control of hypertension, diabetes, HIV, and depression. Results Of the 6,709 veterans enrolled in VACS, 1,624 (24%) reported being food insecure. Food insecurity was independently associated with being African American, earning <$25,000/year, recent homelessness, marijuana use, and depression. Being food insecure was also associated with worse control of hypertension, diabetes, HIV, and depression (p<0.001). Conclusion Food insecurity is prevalent and associated with worse control of medical conditions among veterans who have accessed care in the VA. PMID:25931630

Laccases are increasingly being used in food industry for production of cost-effective and healthy foods. To sustain this trend widespread availability of laccase and efficient production systems have to be developed. The present paper delineate the recent developments that have taken place in understanding the role of laccase action, efforts in overexpression of laccase in heterologous systems, and various cultivation techniques that have been developed to efficiently produce laccase at the industrial scale. The role of laccase in different food industries, particularly the recent developments in laccase application for food processing, is discussed. PMID:21048859

This study evaluated the association between health related quality of life and food security among persons living with HIV (PLHIV). We studied 167 PLHIV who completed questionnaires assessing food security, disease symptomatology, and several domains of the SF-36 health related quality of life survey. HIV disease state was assessed from medical records. Associations between independent and outcome variables were determined through linear regression models. Compared to food security, very low food security was significantly associated with lower mental component summary scores, [average difference -4.98 (95 % CI -9.85, -0.10)]; mental health, [average difference -5.44 (95 % CI -10.08, -0.81)]; and general health, [average difference -5.13 (95 % CI -9.65, -0.65)] after adjusting for covariates. About a fourth of participants experienced severe food insecurity, which negatively influenced their mental health and general wellbeing. The inclusion of resources for food assistance in HIV treatment programs may help ameliorate mental health challenges faced by PLHIV.

A protocol for extraction of yellow mealworm larvae proteins was established, conditions were evaluated and the resulting protein extract was characterised. The freeze-dried yellow mealworm larvae contained around 33% fat, 51% crude protein and 43% true protein on a dry matter basis. The true protein content of the protein extract was about 75%, with an extraction rate of 70% under optimised extraction conditions using 0.25 M NaOH, a NaOH solution:ethanol defatted worm ratio of 15:1 mL/g, 40°C for 1 h and extraction twice. The protein extract was a good source of essential amino acids. The lowest protein solubility in distilled water solution was found between pH 4 and 5, and increased with either increasing or decreasing pH. Lower solubility was observed in 0.5 M NaCl solution compared with distilled water. The rheological tests indicated that temperature, sample concentration, addition of salt and enzyme, incubation time and pH alterations influenced the elastic modulus of yellow mealworm protein extract (YMPE). These results demonstrate that the functional properties of YMPE can be modified for different food applications.

Physically active lifestyles and other health-enhancing behaviors play an important role in preserving executive function into old age. Conversely, emerging research suggests that executive functions facilitate participation in a broad range of healthy behaviors including physical activity and reduced fatty food, tobacco, and alcohol consumption. They do this by supporting the volition, planning, performance monitoring, and inhibition necessary to enact intentions and override urges to engage in health damaging behavior. Here, we focus firstly on evidence suggesting that health-enhancing behaviors can induce improvements in executive function. We then switch our focus to findings linking executive function to the consistent performance of health-promoting behaviors and the avoidance of health risk behaviors. We suggest that executive function, health behavior, and disease processes are interdependent. In particular, we argue that a positive feedback loop may exist whereby health behavior-induced changes in executive function foster subsequent health-enhancing behaviors, which in turn help sustain efficient executive functions and good health. We conclude by outlining the implications of this reciprocal relationship for intervention strategies, the design of research studies, and the study of healthy aging. PMID:27601977

Nutrient dense foods that are associated with better health outcomes tend to cost more per kilocalorie (kcal) than do refined grains, sweets and fats. The price disparity between healthful and less healthful foods appears to be growing. This study demonstrates a new method for linking longitudinal retail price data with objective, nutrient-based ratings of the nutritional quality of foods and beverages. Retail prices for 378 foods and beverages were obtained from major supermarket chains in the Seattle, WA for 2004-8. Nutritional quality was based on energy density (kcal/g) and two measures of nutrient density, calculated using the Naturally Nutrient Rich (NNR) score and the Nutrient Rich Foods index (NRF9.3). Food prices were expressed as $/100g edible portion and as $/1,000 kcal. Foods were stratified by quintiles of energy and nutrient density for analyses. Both measures of nutrient density were negatively associated with energy density and positively associated with cost per 1,000 kcal. The mean cost of foods in the top quintile of nutrient density was $27.20/1,000 kcal and the 4 y price increase was 29.2%. Foods in the bottom quintile cost a mean of $3.32/1000 kcal and the 4 y price increase was 16.1%. There is a growing price disparity between nutrient-dense foods and less nutritious options. Cost may pose a barrier to the adoption of healthier diets and so limit the impact of dietary guidance. Nutrient profiling methods provide objective criteria for tracking retail prices of foods in relation to their nutritional quality and for guiding food and nutrition policy. PMID:25411518
The Baniwa people, a member of the Aruak group which lives in the northwestern Amazon, has a rich mythic tradition that influences how the political, ethical, and practical dimensions of their social life are expressed and that guides the ancestral knowledge that guarantees the group's survival under adverse environmental conditions. The article analyzes myths and rites built around fish as a food source; these have an intimate relationship with cosmological explanations of the origin of the gods, water bodies, and the micro-ecosystems that foster the reproduction of aquatic fauna. Baniwa mythology draws an association between the reproductive processes of fish and a set of social relations involving human and nonhuman societies. Predation and edibility--notions underlying food rites--are viewed as part of a set of practices meant to produce and maintain kinship alliances, ease the food/prey peril, and maintain the cosmic balance that sustains life.

Although the reduction and prevalence of dental caries in many countries has been largely associated with the use of fluorine and improving dental hygiene, eating habits also play a role in the development of caries. Fermentable carbohydrates characteristics of the food, rate of consumption, food protectors, the quality and quantity of saliva indices that determine the remineralization of teeth are factors to be considered. All these elements are analyzed through the sociodemographic, behavioral, physical and biological environment directly or indirectly with diet and caries.

Introduction Dietary phytochemicals are found in plant-based foods such as fruits, vegetables and grains and may be categorised in a nested hierarchical manner with many hundred individual phytochemicals identified to date. To associate phytochemical intakes with positive health outcomes, a fundamental step is to accurately estimate the dietary phytochemical intake from foods reported. The purpose of this systematic review protocol is to describe the process to be undertaken to summarise the evidence for food-based dietary phytochemical intakes and health outcomes for adults. Methods and analysis The review will be undertaken following the PRISMA guidelines and the Cochrane Handbook for Systematic Reviews of Interventions using the Review Manager software. Phytochemical subclasses (phenolic acids, flavanols, etc) will be used to search for relevant studies using the Web of Science and Scopus scientific databases. The retrieved studies will be screened based on inclusion of natural whole food items and health outcomes. Phytochemical studies related to cardiovascular disease, cancer, overweight, glucose tolerance, digestive, reproductive, macular and bone health and mental disorders, fatigue and immunity will be examined based on prior scoping. The evidence will be aggregated by the food types and health outcomes. Comparison of differences in the outcomes for randomised controlled trials and observational studies will be undertaken. The strength of the review lies in its focus on whole food items and health conditions rather than one type of phytochemical related to one single health condition. Subgroup and sensitivity analyses will be conducted where an adequate number of publications are found per phytochemical subclass. Dissemination By comparing the outcomes from experimental and observational studies, the review will determine whether the overall conclusions related to the phytochemical subclasses are the same between study types for the identified health

This review addresses epidemiological, public health, and social policy implications of categorizing young children and their adult female caregivers in the United States as food secure when they live in households with “marginal food security,” as indicated by the U.S. Household Food Security Survey Module. Existing literature shows that households in the US with marginal food security are more like food-insecure households than food-secure households. Similarities include socio-demographic characteristics, psychosocial profiles, and patterns of disease and health risk. Building on existing knowledge, we present new research on associations of marginal food security with health and developmental risks in young children (<48 mo) and health in their female caregivers. Marginal food security is positively associated with adverse health outcomes compared with food security, but the strength of the associations is weaker than that for food insecurity as usually defined in the US. Nonoverlapping CIs, when comparing odds of marginally food-secure children’s fair/poor health and developmental risk and caregivers’ depressive symptoms and fair/poor health with those in food-secure and -insecure families, indicate associations of marginal food security significantly and distinctly intermediate between those of food security and food insecurity. Evidence from reviewed research and the new research presented indicates that households with marginal food security should not be classified as food secure, as is the current practice, but should be reported in a separate discrete category. These findings highlight the potential underestimation of the prevalence of adverse health outcomes associated with exposure to lack of enough food for an active, healthy life in the US and indicate an even greater need for preventive action and policies to limit and reduce exposure among children and mothers.

Home economics and health teachers are to be found in many parts of the world. They teach students about food in relation to its nutritional, safety and environmental properties. The effects of such teaching might be expected to be reflected in the food knowledge of adults who have undertaken school education in these areas. This study examined the food knowledge associations of school home economics and health education among Australian adults. Two separate online surveys were conducted nationwide among 2022 (November 2011) and 2146 Australian adults (November-December 2012). True/false and multiple choice questions in both surveys were used to assess nutrition, food safety and environmental knowledge. Knowledge scores were constructed and compared against respondents' experience of school health or home economics education via multiple regression analyses. The results from both studies showed that home economics (and similar) education was associated with higher levels of food knowledge among several age g
