    The research reported in this document was conducted as a part of the Hanford Environmental Dose Reconstruction (HEDR) Project. The objective of the HEDR Project is to estimate the radiation doses that people could have received from operations at the Hanford Site. Information required to estimate these doses includes estimates of the amounts of potentially contaminated foods that individuals in the region consumed during the study period. In that general framework, the objective of the Food Consumption Task was to develop a capability to provide information about the parameters of the distribution(s) of daily food consumption for representative groups in the population for selected years during the study period. This report describes the methods and data used to estimate food consumption and presents the results developed for Phase I of the HEDR Project.

  2. Food consumption trends and drivers

    A picture of food consumption (availability) trends and projections to 2050, both globally and for different regions of the world, along with the drivers largely responsible for these observed consumption trends are the subject of this review. Throughout the world, major shifts in dietary patterns are occurring, even in the consumption of basic staples towards more diversified diets. Accompanying these changes in food consumption at a global and regional level have been considerable health consequences. Populations in those countries undergoing rapid transition are experiencing nutritional transition. The diverse nature of this transition may be the result of differences in socio-demographic factors and other consumer characteristics. Among other factors including urbanization and food industry marketing, the policies of trade liberalization over the past two decades have implications for health by virtue of being a factor in facilitating the ‘nutrition transition’ that is associated with rising rates of obesity and chronic diseases such as cardiovascular disease and cancer. Future food policies must consider both agricultural and health sectors, thereby enabling the development of coherent and sustainable policies that will ultimately benefit agriculture, human health and the environment.

    Findings from transition studies as well as studies of student food show that the transition from living at home to independent living influences student food consumption and that food consumption might be problematic during this period. Furthermore, both students' enactment of being in transition and the food habits and practices they bring with…

  4. Thought for food: imagined consumption reduces actual consumption.

    The consumption of a food typically leads to a decrease in its subsequent intake through habituation--a decrease in one's responsiveness to the food and motivation to obtain it. We demonstrated that habituation to a food item can occur even when its consumption is merely imagined. Five experiments showed that people who repeatedly imagined eating a food (such as cheese) many times subsequently consumed less of the imagined food than did people who repeatedly imagined eating that food fewer times, imagined eating a different food (such as candy), or did not imagine eating a food. They did so because they desired to eat it less, not because they considered it less palatable. These results suggest that mental representation alone can engender habituation to a stimulus.

    Food consumption is an important factor in shaping the sustainability of our food supply. The present paper empirically explores different types of sustainable food behaviors. A distinction between sustainable product choices and curtailment behavior has been investigated empirically and predictors of the two types of behavior have been identified. Respondents were classified into four segments based on their sustainable food behaviors: unsustainers, curtailers, product-oriented consumers, and sustainers. Significant differences between the segments were found with regard to food choice motives, personal and social norms, food involvement, subjective knowledge on sustainable food, ability to judge how sustainably a product has been produced and socio-demographics. It is concluded that distinguishing between behavioral strategies toward sustainable food consumption is important as consumer segments can be identified that differ both in their level of sustainable food consumption and in the type of behavior they employ.

    Recent nutritional and public health research has focused on how the availability of various types of food in a person's immediate area or neighborhood influences his or her food choices and eating habits. It has been theorized that people living in areas with a wealth of unhealthy fast-food options may show higher levels of fast-food consumption, a factor that often coincides with being overweight or obese. However, measuring food availability in a particular area is difficult to achieve consistently: there may be differences in the strict physical locations of food options as compared to how individuals perceive their personal food availability, and various studies may use either one or both of these measures. The aim of this study was to evaluate the association between weekly fast-food consumption and both a person's perceived availability of fast-food and an objective measure of fast-food presence - Geographic Information Systems (GIS) - within that person's neighborhood. A randomly selected population-based sample of eight counties in South Carolina was used to conduct a cross-sectional telephone survey assessing self-report fast-food consumption and perceived availability of fast food. GIS was used to determine the actual number of fast-food outlets within each participant's neighborhood. Using multinomial logistic regression analyses, we found that neither perceived availability nor GIS-based presence of fast-food was significantly associated with weekly fast-food consumption. Our findings indicate that availability might not be the dominant factor influencing fast-food consumption. We recommend using subjective availability measures and considering individual characteristics that could influence both perceived availability of fast food and its impact on fast-food consumption. If replicated, our findings suggest that interventions aimed at reducing fast-food consumption by limiting neighborhood fast-food availability might not be completely effective. PMID

  7. Convenience food products. Drivers for consumption.

    Convenience is one of the big trends in the food business. The demand for convenience food products is steadily increasing; therefore, understanding convenience food consumption is an important issue. Despite being vital properties of convenience food, saving time and effort have not been very successful constructs for predicting convenience food consumption. To examine a wide range of possible drivers for convenience food consumption, the present study uses a convenience food frequency questionnaire that asks about consumption behavior. A paper-and-pencil questionnaire was sent out to a representative sample of people in German-speaking Switzerland and yielded N = 918 complete datasets from persons mainly responsible for buying and preparing food in the household. The various convenience food products could be categorized into four groups, which we labeled as highly processed food items, moderately processed food items, single components, and salads. Fifteen drivers were found to have a significant impact either on total convenience consumption or on one of the identified categories. Strong predictors were age, concern about naturalness, nutrition knowledge, and cooking skills. PMID:20832437

    The aims of the present work were to study motives underlying Uruguayan consumers' food choice behaviour and to study the consumption frequency of some selected food items. A modification of the Food Choice Questionnaire and a food frequency questionnaire was administered to a group of 200 Uruguayan consumers. Feeling good and safety, sensory appeal and health and nutrient content were rated as the most important factors, while familiarity was rated as the least important. Using hierarchical cluster analysis, three clusters with different choice patterns were identified. Frequency of consumption of fruits, vegetables, milk and dairy products, and whole cereals, increased as the importance attributed to health and nutrition increased; consumption of fatty foods decreased.

    This report details the methods used and the results of the study on the estimated historic levels of food consumption by individuals in the Hanford Environmental Dose Reconstruction (HEDR) study area from 1945--1957. This period includes the time of highest releases from Hanford and is the period for which data are being collected in the Hanford Thyroid Disease Study. These estimates provide the food-consumption inputs for the HEDR database of individual diets. This database will be an input file in the Hanford Environmental Dose Reconstruction Integrated Code (HEDRIC) computer model that will be used to calculate the radiation dose. The report focuses on fresh milk, eggs, lettuce, and spinach. These foods were chosen because they have been found to be significant contributors to radiation dose based on the Technical Steering Panel dose decision level.

    2010-12-01

    The increasing importance of convenience in consumer food choices has attracted researchers' interest. In the effort to understand how convenience affects consumers' food preferences, values are believed to play an important role. The present study attempts to examine the way personal values suggested by Schwartz (1992) are associated with behaviour and attitudes regarding convenience food. A number of constructs describing food related attitudes and behaviours were developed and their relationship with personal values was analyzed following the methodology proposed by Brunsø, Scholderer, and Grunert (2004). Data were collected through a questionnaire survey from a random sample of consumers in Thessaloniki city, Greece. The results reveal that convenience food consumption and convenience orientation in the food domain are mainly connected with values that motivate people to seek new experiences, act independently and enhance their own personal interests, while are in conflict with values of conservation and self-transcendence. The opposite holds for other food related attitudes and behaviours like involvement with cooking and variety in diet. The findings seem to be of particular interest not only for marketers of food products, but also for food policy makers. PMID:20875475

    Food consumption is associated with various environmental impacts, and consumers' food choices therefore represent important environmental decisions. In a large-scale survey, we examined consumers' beliefs about ecological food consumption and their willingness to adopt such behaviors. Additionally, we investigated in more detail how different motives and food-related attitudes influenced consumers' willingness to reduce meat consumption and to buy seasonal fruits and vegetables. We found consumers believed avoiding excessive packaging had the strongest impact on the environment, whereas they rated purchasing organic food and reducing meat consumption as least environmentally beneficial. Similarly, respondents appeared to be most unwilling to reduce meat consumption and purchase organic food. Taste and environmental motives influenced consumers' willingness to eat seasonal fruits and vegetables, whereas preparedness to reduce meat consumption was influenced by health and ethical motives. Women and respondents who preferred natural foods were more willing to adopt ecological food consumption patterns. PMID:21896294

    The problem of expanding food supply has been made more complex and more dependent on technological progress by the encroachment of a burgeoning population on a limited land area. Rapid growth in the rural labor force in the low-income developing countries not only increases the problem of providing adequate employment, particularly in the face of diminishing scope for expanding the land area, but also reduces the possibility of solving poverty problems simply by a redistribution of assets and income flows. Section II reviews past trends and current levels of food production, trade, and consumption. Section III discusses a controversial issue: the extent and seriousness of food deprivation. These sections lead to the same conclusion: the choice of development strategy is decisive in determining the level at which the food equation balances. An examination of contrasting development strategies and their implications for food production (Section IV) is followed by an exploration of the emerging consensus on the complex and difficult task of implementing a unimodal pattern of accelerated agricultural development, consistent with a high rate of growth in employment and food consumption. Interacting health-, nutrition-, and family-planning programs are viewed as important claimants of organizational and other resources. The review leads to the conclusion that reduction of malnutrition and related manifestations of poverty requires a set of interacting forces, characterized as a ring, that link nutritional need, generation of effective demand for food on the part of the poor, increased employment, a strategy of development that structures demand towards goods and services that have a high employment content, production of wage goods, and an emphasis on growth in agriculture. 183 references, 4 tables.

    The aim of this study was to examine the associations of food store choice with food consumption among urban slum women. A cross-sectional survey was carried out among 188 urban slum women (19-50 years old) in Jakarta, Indonesia. A semiquantitative food frequency questionnaire was used to assess food consumption. Associations between food consumption and food store choice were tested by linear regression. This study found that frequencies of buying food from small shops (warung), street food vendors, and modern food stores were significantly associated with consumption of snacks, mixed dishes, and fruit respectively. In addition, buying food from traditional markets and small cafes (warung makan) was not significantly associated with particular types of food consumption. As modern food stores are rarely utilized by these women, small shops (warung) and street food vendors are likely to be important channels to improve slum dwellers' diet. PMID:27208014

    The aim of this study was to investigate whether food reward plays a role in the stimulating effect of moderate alcohol consumption on subsequent food intake. In addition, we explored the role of oral and gut sensory pathways in alcohol's effect on food reward by modified sham feeding (MSF) or consumption of a preload after alcohol intake.In a single-blind crossover design, 24 healthy men were randomly assigned to either consumption of vodka/orange juice (20 g alcohol) or orange juice only, followed by consumption of cake, MSF of cake or no cake. Food reward was evaluated by actual food intake measured by an ad libitum lunch 45 min after alcohol ingestion and by behavioural indices of wanting and liking of four food categories (high fat, low fat, sweet and savoury).Moderate alcohol consumption increased food intake during the ad libitum lunch by 11% (+338 kJ, P = 0.004). Alcohol specifically increased intake (+127 kJ, P <0.001) and explicit liking (P = 0.019) of high-fat savoury foods. Moreover, moderate alcohol consumption increased implicit wanting for savoury (P = 0.013) and decreased implicit wanting for sweet (P = 0.017) before the meal. Explicit wanting of low-fat savoury foods only was higher after alcohol followed by no cake as compared to after alcohol followed by cake MSF (P = 0.009), but not as compared to alcohol followed by cake consumption (P = 0.082). Both cake MSF and cake consumption had no overall effect on behavioural indices of food reward.To conclude, moderate alcohol consumption increased subsequent food intake, specifically of high-fat savoury foods. This effect was related to the higher food reward experienced for savoury foods. The importance of oral and gut sensory signalling in alcohol's effect on food reward remains largely unclear.

    Estimation of food consumption and nutrient intake is a topic of growing interest. Currently, both in Europe and in Spain, there are numerous sources of information on food consumption, that we provide information on different levels: national, household and individual, all of them are useful, but including some limitations, mainly arising from the lack of accurate data on food purchased but not consumed. The data obtained allow, among other things, meet dietary habits, explore the food quality, study the energy and nutrient intake and / or assessing exposure to food risks. Among the existing sources in Spain can highlight two surveys especially useful: the Household Budget Survey of the National Statistics Institute (INE) and Food Consumption Panel Ministry of Agriculture, Food and Environment (MAGRAMA). Both provide for many years food consumption but, lately, only in households. Both European and Spanish would be necessary to improve the usefulness of the data, standardize the type of survey used and could be comparable between them. PMID:25719768

    Vegetarian dietary patterns have been reported to be associated with a number of favourable health outcomes in epidemiological studies, including the Adventist Health Study 2 (AHS-2). Such dietary patterns may vary and need further characterisation regarding foods consumed. The aims of the present study were to characterise and compare the food consumption patterns of several vegetarian and non-vegetarian diets. Dietary intake was measured using an FFQ among more than 89 000 members of the AHS-2 cohort. Vegetarian dietary patterns were defined a priori, based on the absence of certain animal foods in the diet. Foods were categorised into fifty-eight minor food groups comprising seventeen major food groups. The adjusted mean consumption of each food group for the vegetarian dietary patterns was compared with that for the non-vegetarian dietary pattern. Mean consumption was found to differ significantly across the dietary patterns for all food groups. Increased consumption of many plant foods including fruits, vegetables, avocados, non-fried potatoes, whole grains, legumes, soya foods, nuts and seeds was observed among vegetarians. Conversely, reduced consumption of meats, dairy products, eggs, refined grains, added fats, sweets, snack foods and non-water beverages was observed among vegetarians. Thus, although vegetarian dietary patterns in the AHS-2 have been defined based on the absence of animal foods in the diet, they differ greatly with respect to the consumption of many other food groups. These differences in food consumption patterns may be important in helping to explain the association of vegetarian diets with several important health outcomes. PMID:25247790

    This report was written to provide the food consumption methodology to be used in the Hanford Environmental Dose Reconstruction (HDER) Project beyond Phase I (which ended in July 1990). In Phase I (Callaway 1992), baseline food consumption estimates (grams per day) for 10 primary food types in the original 10-county study region were derived from the 1977--1978 National Food Consumption Survey (USDA 1983). The baseline estimates were multiplied by the 1945:1977 ratios to produce consumption estimates for 1945. This ratio backcasting method used in Phase I to project consumption estimates from 1977 back to 1945 will be refined using additional USDA data to improve and document the acceptability of the ratios for deriving backcast consumption estimates. The number of food types and population groups will be expanded to provide more disaggregated estimates of food consumption. Food consumption estimates will be developed for 1945, 1951, and 1957. A database of individual diets will be created from which daily diets will be randomly selected for use in the dose model to calculate doses for reference individuals.

    The present study explored the relationships between fried food consumption and metabolic risk factors and hypertension in Korean adults. The study was based on the fifth Korean National Health and Nutrition Examination Survey between 2010 and 2011. A total of 9221 Korean adults aged ≥19 years were studied. Fried food consumption was assessed using a validated FFQ. Metabolic risk factors such as waist circumference, fasting plasma glucose (FPG), TAG, HDL-cholesterol and systolic and diastolic blood pressure (SBP and DBP) were measured. Hypertension was defined as SBP≥140 mmHg, DBP≥90 mmHg or current use of antihypertensive medication. Adjusted OR for elevated blood pressure significantly increased in men (OR 1·62; 95% CI 1·11, 2·37; P(trend)=0·0447) and women (OR 2·20; 95% CI 1·21, 4·00; P(trend)=0·0403) with a greater than twice a week consumption of fried food compared with those who rarely consumed fried food. However, fried food consumption was not associated with other metabolic risk factors (abdominal obesity, high FPG, hypertriacylglycerolaemia, low HDL-cholesterol and the metabolic syndrome). The adjusted OR for hypertension increased by 2·4-fold in women (OR 2·37; 95% CI 1·19, 4·72; P(trend)=0·0272) with a greater than twice a week fried food consumption compared with those who rarely consumed it. No significant association was found between fried food consumption and hypertension in men. This study suggests that frequent fried food consumption is associated with hypertension in Korean women. Further studies are needed to investigate the effect of different types of fried foods on hypertension. PMID:26449129

    The increasing consumption of junk food and snacks in Chile in recent years and its association with marketing strategies and prevalent diseases, is reviewed. In the context of world economy, junk food is a global phenomenon. The availability of junk food and snacks at low prices and marketing has triggered an evolution of consumption of foods that require neither the structure nor the preparation of a formal meal. Many studies have suggested that the increase in snack consumption is associated with an increase in obesity, tooth decay and other chronic diseases among children and adolescents. The hypothesis suggests a link between the pattern of snack consumption and an increase increase in the energy density of food consumed, a decrease in satiety, passive over consumption, and an increase in obesity. Between 1977 and 1996, the contribution: of snacks to daily energy intake among children between 2 and 5 years increased by 30% in the United States. In each age group in Chile the frequency of non-transmissible chronic diseases is increasing due primarily to a westernized diet that is high in fat, cholesterol, sodium, and sugar and a sedentary lifestyle. Education about junk food consumption and healthy eating habits in the family, starling since childbirth and public policies about healthy lifestyles should be strengthened. PMID:15631213

    Serotonergic involvement has been implicated in preferential consumption of treat foods. We tested the effect of acute tryptophan depletion (ATD) on food consumption by overweight and lean adults with and without a history of recurrent major depressive disorder (MDD). ATD and taste-matched placebo challenges were administered double-blind in counter-balanced order. Participants were classified as lean (n = 36) or overweight (n=19) on the basis of body mass index (BMI). Total calorie, carbohydrate, protein, and sweet food consumption were assessed via a test meal 8-hours following ATD. Four food items of comparable palatability were offered as a part of the test: two sweet (one carbohydrate-rich, and one protein-rich) and two non-sweet (one carbohydrate-rich, and one protein-rich). As compared to the placebo challenge, ATD significantly increased sweet calorie intake among overweight participants and increased their propensity to consume sweet food first before any other type of food. Lean participants’ sweet calorie intake and food preference were unaffected by ATD. Findings suggest serotonergic involvement in the sweet food consumption by overweight individuals. PMID:19171315

    Background The purpose of this study was to investigate relationships between ideological beliefs, perceptions of the importance of health behaviours, health attitudes, food consumption, and Body Mass Index (BMI). A behavioural model was hypothesized based on the Theory of Reasoned Action (Fishbein & Ajzen, 1975). Methods A survey was conducted among shoppers aged between 40 and 70 years at Eastland Shopping Centre, Melbourne, Australia. The hypothesized model was tested with this empirical data (n = 410) for younger (n = 151) and older (n = 259) age groups using structural equation modelling. Results The findings generally support the study hypotheses. For both groups, egalitarianism had a direct and positive influence on perceptions of the importance of health behaviours. Materialism and masculinity impacted negatively on health attitudes, which positively influenced importance of health behaviours. Perceptions of importance of health behaviours impacted positively on the consumption of healthy foods such as vegetables and fruits, but negatively on consumption of unhealthy foods including sweets and fats. However, BMI was significantly influenced by the consumption of unhealthy foods (e.g., sugar and fats) only for the younger age group. Hence, the associations between beliefs, attitudes, consumption behaviours, and BMI outcomes differed between younger and older age populations. Conclusion Social ideological beliefs appear to influence health attitudes and thereafter, the consumption of healthy and unhealthy foods and BMI via different pathways. PMID:18412977

    A total of 100 American females (mean age = 20.8 years) completed a questionnaire, in which their beliefs, evaluations, liking and consumption (frequency, consumption compared to others, intention to consume) of milk, cheese, ice cream, chocolate and "high-fat foods" were measured. For the design and analysis, the basic frame of reference was the Fishbein-Ajzen model of reasoned action, but the final analyses were carried out with stepwise multiple regression analysis. In addition to the components of the Fishbein-Ajzen model, beliefs and evaluations were used as independent variables. On the average, subjects reported liking all the products but not "high-fat foods", and thought that milk and cheese were "good for you" whereas the remaining items were "bad for you". Principal component analysis for beliefs revealed factors related to pleasantness/benefit aspects, to health and weight concern and to the "functionality" of the foods. In stepwise multiple regression analyses, liking was the predominant predictor of reported consumption for all the foods, but various belief factors, particularly those related to concern with weight, also significantly predicted consumption. Social factors played only a minor role. The multiple R's of the predictive functions varied from 0.49 to 0.74. The fact that all four foods studied elicited individual sets of beliefs and belief structures, and that none of them was rated similar to the generic "high-fat foods", emphasizes that consumers attach meaning to integrated food entities rather than to ingredients.

    In Western countries where food supply is satisfactory, consumers organize their diets around a large combination of foods. It is the purpose of this article to examine how recent nonnegative matrix factorization (NMF) techniques can be applied to food consumption data to understand these combinations. Such data are nonnegative by nature and of high dimension. The NMF model provides a representation of consumption data through latent vectors with nonnegative coefficients, that we call consumption systems (CS), in a small number. As the NMF approach may encourage sparsity of the data representation produced, the resulting CS are easily interpretable. Beyond the illustration of its properties we provide through a simple simulation result, the NMF method is applied to data issued from a French consumption survey. The numerical results thus obtained are displayed and thoroughly discussed. A clustering based on the k-means method is also achieved in the resulting latent consumption space, to recover food consumption patterns easily usable for nutritionists. PMID:21418050

    We prospectively assessed the (1) frequency and socio-economic correlates of takeaway food consumption during adolescence; and (2) association between frequent takeaway food consumption with intakes of major food groups and anthropometric measures and blood pressure (BP). In total, 699 Sydney schoolchildren (380 girls and 319 boys) who had dietary data at both 12 and 17 years of age were included for analyses. Takeaway food consumption was self-reported and based on a single question. Anthropometric measures and BP were collected. The proportion of participants who ate takeaway foods once per week or more increased significantly over 5 years from the age of 12 to 17 years: 35·5-44·1 % (P<0·0001). In total, 12-year-old girls compared with boys had reduced odds of takeaway foods once per week or more at the age of 17 years (P=0·01), multivariable-adjusted OR 0·63 (95 % CI 0·44, 0·90). In total, 12-year-old children who ate takeaway foods once per week or more had significantly lower mean fruit (220·3 v. 253·0 g/d; P=0·03) and vegetable consumption (213·2 v. 247·7 g/d; P=0·004), 5 years later (at 17 years of age). Frequent takeaway food consumption at the age of 12 years was not associated with anthropometric indices and BP at the age of 17 years. Consumption of takeaway foods became more frequent during adolescence, particularly among boys, and it was associated with reduced intake of fruits and vegetables. PMID:27046032

  11. A review of visual cues associated with food on food acceptance and consumption.

    Several sensory cues affect food intake including appearance, taste, odor, texture, temperature, and flavor. Although taste is an important factor regulating food intake, in most cases, the first sensory contact with food is through the eyes. Few studies have examined the effects of the appearance of a food portion on food acceptance and consumption. The purpose of this review is to identify the various visual factors associated with food such as proximity, visibility, color, variety, portion size, height, shape, number, volume, and the surface area and their effects on food acceptance and consumption. We suggest some ways that visual cues can be used to increase fruit and vegetable intake in children and decrease excessive food intake in adults. In addition, we discuss the need for future studies that can further establish the relationship between several unexplored visual dimensions of food (specifically shape, number, size, and surface area) and food intake.

    This paper investigated Vietnamese food consumption patterns, in terms of food quantity and total energy intake, and examined how these food patterns differ by demography and socio-economic status for the Vietnamese. Data used in this paper were from the Vietnam Living Standards Survey national cross-sectional study in 1997-1998. Descriptive and regression analyses identified different food consumption patterns among 5,999 participating households. Results showed that the traditional diet in Vietnam is high in carbohydrates and low in fat; together with unaccounted eating-out foods, these dietary patterns may contribute to the population's low energy intake. The regression models identified place of residence, family income, household size, education of the head of household, ethnicity, and ecological region to be significantly associated with energy intake. Socio-economic and demographic status must be considered in developing national strategies and implementing plans of action to improve nutrition. PMID:15003913

  13. Neighborhood fast food restaurants and fast food consumption: A national study

    PubMed Central

    2011-01-01

    Background Recent studies suggest that neighborhood fast food restaurant availability is related to greater obesity, yet few studies have investigated whether neighborhood fast food restaurant availability promotes fast food consumption. Our aim was to estimate the effect of neighborhood fast food availability on frequency of fast food consumption in a national sample of young adults, a population at high risk for obesity. Methods We used national data from U.S. young adults enrolled in wave III (2001-02; ages 18-28) of the National Longitudinal Study of Adolescent Health (n = 13,150). Urbanicity-stratified multivariate negative binomial regression models were used to examine cross-sectional associations between neighborhood fast food availability and individual-level self-reported fast food consumption frequency, controlling for individual and neighborhood characteristics. Results In adjusted analysis, fast food availability was not associated with weekly frequency of fast food consumption in non-urban or low- or high-density urban areas. Conclusions Policies aiming to reduce neighborhood availability as a means to reduce fast food consumption among young adults may be unsuccessful. Consideration of fast food outlets near school or workplace locations, factors specific to more or less urban settings, and the role of individual lifestyle attitudes and preferences are needed in future research.

    This paper examines the motives and experiences of attendees at a Slow Food festival to gain an understanding of how people engage with ethical consumer projects. Slow Food is a global social movement aimed at promoting food that is regionally, ethically, and sustainably produced, and convivially consumed. The movement uses culinary tourist events, such as food festivals and farmers' markets, to promote its philosophy and attract new members. There have been no empirical studies of ethical consumption using a Slow Food event as a case study. This study uses an ethnographic approach and a framework of virtue ethics to explore the views of people attending a major Slow Food festival in the city of Melbourne, Australia. Semi-structured interviews were conducted in situ with 33 participants (19 consumers and 14 stallholders) to discover their rationales for attending the festival, and their perspectives on ethical consumption. Transcripts were coded and thematically analysed, resulting in three themes reflecting varying degrees of public virtues (altruistic motivations) and private virtues (personal wellbeing): the quest for virtuous lifestyles through ethical consumption, the importance of co-production, and the challenges of putting ethical consumer projects like Slow Food into daily practice. The findings reveal the manner in which virtue ethics affects foodways and highlights the contingent and challenging nature of practising ethical eating. PMID:25934088

    Nutrition labelling is an important strategic approach for encouraging consumers to make healthier food choices. The availability of highly palatable foods labelled as 'low fat or reduced calorie' may encourage the over-consumption of these products. This study aimed to determine whether the manipulation of nutrition labelling information can influence food portion size consumption. Normal and overweight men (n=24) and women (n=23) were served an identical lunch meal on three separate days, but the information they received prior to consuming the lunch meal was manipulated as follows: "baseline", "high fat/energy" and "low fat/energy". Food and energy intake was significantly increased in the low fat/energy condition compared with both baseline and the high fat/energy condition. An additional 3% (162 kJ) energy was consumed by subjects under the low fat/energy condition compared to baseline. No differences were observed between the baseline and high fat/energy condition. Subjects who consumed most in the low fat/energy condition were found to be mostly men, to have a higher BMI and to be overweight. Low fat/energy information can positively influence food and energy intake, suggesting that foods labelled as 'low fat' or 'low calorie' may be one factor promoting the consumption of large food portions.

  16. Organic food consumption in Poland: Motives and barriers.

    PubMed

    Bryła, Paweł

    2016-10-01

    This paper aims to investigate selected aspects of organic food consumption in Poland. We conducted a survey in a representative sample of 1000 consumers. Polish consumers are convinced that organic food is more expensive, healthier, more environmentally friendly, more tasty and more authentic than conventional food. They believe its arouses more trust, has a better quality, is subject to more strict controls, and is produced in a more traditional way. According to Polish consumers, the most important characteristics of organic food are healthiness and high quality. The perceived authenticity of organic food depends on its natural taste, product quality, labelling, in particular having a European quality sign, as well as the retailer type and a separate exposition place in the points of purchase (merchandising). The critical barrier to the development of the organic food market in Poland is the high price, followed by an insufficient consumer awareness, low availability of organic products, short expiry dates and low visibility in the shop. The principal motives of organic food selection in Poland include: healthiness, ecological character of the product, food safety considerations, superior taste, and quality assurance. We identified the motives for and barriers to organic food consumption in Poland. PMID:27417333

    The impact of television (TV) advertisements (commercials) on children's eating behaviour and health is of critical interest. In a preliminary study we examined lean, over weight and obese children's ability to recognise eight food and eight non-food related adverts in a repeated measures design. Their consumption of sweet and savoury, high and low fat snack foods were measured after both sessions. Whilst there was no significant difference in the number of non-food adverts recognised between the lean and obese children, the obese children did recognise significantly more of the food adverts. The ability to recognise the food adverts significantly correlated with the amount of food eaten after exposure to them. The overall snack food intake of the obese and overweight children was significantly higher than the lean children in the control (non-food advert) condition. The consumption of all the food offered increased post food advert with the exception of the low-fat savoury snack. These data demonstrate obese children's heightened alertness to food related cues. Moreover, exposure to such cues induce increased food intake in all children. As suggested the relationship between TV viewing and childhood obesity appears not merely a matter of excessive sedentary activity. Exposure to food adverts promotes consumption. PMID:15010186

    In an environment with easy access to highly palatable and energy-dense food, food-related cues drive food-seeking regardless of satiety, an effect that can lead to obesity. The ventral tegmental area (VTA) and its mesolimbic projections are critical structures involved in the learning of environmental cues used to predict motivationally relevant outcomes. Priming effects of food-related advertising and consumption of palatable food can drive food intake. However, the mechanism by which this effect occurs, and whether these priming effects last days after consumption, is unknown. Here, we demonstrate that short-term consumption of palatable food can prime future food approach behaviors and food intake. This effect is mediated by the strengthening of excitatory synaptic transmission onto dopamine neurons that is initially offset by a transient increase in endocannabinoid tone, but lasts days after an initial 24-h exposure to sweetened high-fat food (SHF). This enhanced synaptic strength is mediated by a long-lasting increase in excitatory synaptic density onto VTA dopamine neurons. Administration of insulin into the VTA, which suppresses excitatory synaptic transmission onto dopamine neurons, can abolish food approach behaviors and food intake observed days after 24-h access to SHF. These results suggest that even a short-term exposure to palatable foods can drive future feeding behavior by “rewiring” mesolimbic dopamine neurons. PMID:26884159

    Current theoretical models attempting to explain diet-related weight status among children center around three individual-level theories. Alone, these theories fail to explain why children are engaging or not engaging in health-promoting eating behaviors. Our Comprehensive Child Consumption Patterns model takes a comprehensive approach and was developed specifically to help explain child food consumption behavior and addresses many of the theoretical gaps found in previous models, including integration of the life course trajectory, key influencers, perceived behavioral control, and self-regulation. Comprehensive Child Consumption Patterns model highlights multiple levels of the socioecological model to explain child food consumption, illustrating how negative influence at multiple levels can lead to caloric imbalance and contribute to child overweight and obesity. Recognizing the necessity for multi-level and system-based interventions, this model serves as a template for holistic, integrated interventions to improve child eating behavior, ultimately impacting life course health development.

    The present study compared how intrinsic (sensory) and extrinsic (packaging) product properties influence actual food choice in combination with the concept of product appropriateness in a specific consumption context. Food choice of seven test products was measured in three breakfast sessions within a simulated cafeteria setting with subsequent product consumption. Test products were five breakfast drinks and two dessert products considered as inappropriate for breakfast. One hundred and three participants took part in a blind taste session, after which they chose one out of the seven foods to consume for breakfast. In a second session (familiar package session), the same participants based their choice on the package of the seven foods they tasted in the first session. An additional group of 65 participants took part in a third naïve package session, where they chose just on the basis of package without being previously exposed to the foods. Results showed that food choices in the naïve package session were guided by the package that labelled the products as "breakfast product". Food choices in the blind session were strongly correlated (r = 0.8) with the liking of the products. Food choice in the "familiar package session" lay between the blind and naïve package session. It is concluded that food choice in a simulated cafeteria setting is guided by extrinsic (package) as well as intrinsic (sensory) properties and both can act as a cue for product appropriateness given a specific consumption context. Depending on the salience of either intrinsic or extrinsic properties during the choice moment their impact on choice is stronger. PMID:24845783

    Soda consumption may contribute to weight gain over time. Objective data were used to determine whether soda consumption predicts weight gain or changes in glucose regulation over time. Subjects without diabetes (128 men, 75 women; mean age 34.3±8.9 years; mean body mass index [BMI] 32.5±7.4; mean percentage body fat 31.6%±8.6%) self-selected their food from an ad libitum vending machine system for 3 days. Mean daily energy intake was calculated from food weight. Energy consumed from soda was recorded as were food choices that were low in fat (<20%) or high in simple sugars (>30%). Food choices were expressed as percentage of daily energy intake. A subset of 85 subjects had measurement of follow-up weights and oral glucose tolerance (57 men, 28 women; mean follow-up time=2.5±2.1 years, range 6 months to 9.9 years). Energy consumed from soda was negatively related to age (r=–0.27, P=0.0001), and choosing low-fat foods (r=−0.35, P<0.0001), but positively associated with choosing solid foods high in simple sugars (r=0.45, P<0.0001) and overall average daily energy intake (r=0.46, P<0.0001). Energy intake from food alone did not differ between individuals who did and did not consume beverage calories (P=0.11). Total daily energy intake had no relationship with change in weight (P=0.29) or change in glucose regulation (P=0.38) over time. However, energy consumed from soda correlated with change in weight (r=0.21, P=0.04). This relationship was unchanged after adjusting for follow-up time and initial weight. Soda consumption is a marker for excess energy consumption and is associated with weight gain. PMID:24321742

    The consumption of specific functional foods (FF) and some determinants of FF item selection were assessed using a questionnaire administered to 1112 individuals in the Canary Islands (Spain). Food items considered were Milk products: easily digestible milk (or milk low in lactose), milk enriched with vitamins and/or minerals, skimmed milk with soluble fiber, milk with royal jelly, milk with modified fatty acids (omega 3), milk products low in fat, pro-biotic foods (yoghurt and fermented milk) and yoghurt with phytosterols; Cereals: fortified breakfast cereals, wholemeal cereals and energy bars; Drinks: juices and enriched drinks, stimulating drinks and isotonic drinks; DHA-enriched, low cholesterol eggs; Meat products: low salt sausages and cooked low fat ham; Fats: enriched margarine, margarine rich in phytosterols and sunflower oil rich in oleic acid; Condiments: iodated salt. These food items were organized into 7 FF groups (milk products, cereals, fortified drinks, DHA eggs, meat product, fats, condiments). The results indicated that the highest prevalence was fortified drinks (63.6%; 95% CI: 60.7-66.5). Overall FF consumption prevalence was 80.1% (95% CI: 77-83): single FF item consumption being rare. There were significant inter-group relationships, and some group intakes (milk products, cereals and drinks) were related to age but with no overall relationship between consumption and age. The education level was significantly related to the consumption of cereals, drinks, meat products and condiments (χ2 test p = 0.04). Some specific FF item consumption segregated with environment (rural or urban) but with no overall significant relationship between the FF group and environment or gender. PMID:21959777

    Micronutrient deficiency remains a serious problem in Indonesia with approximately 100 million people, or 40% of the population, suffering from one or more micronutrient deficiencies. In rural areas with poor market access, forests and trees may provide an essential source of nutritious food. This is especially important to understand at a time when forests and other tree-based systems in Indonesia are being lost at unprecedented rates. We use food consumption data from the 2003 Indonesia Demographic Health Survey for children between the ages of one and five years and data on vegetation cover from the Indonesian Ministry of Forestry to examine whether there is a relationship between different tree-dominated land classes and consumption of micronutrient-rich foods across the archipelago. We run our models on the aggregate sample which includes over 3000 observations from 25 provinces across Indonesia as well as on sub-samples from different provinces chosen to represent the different land classes. The results show that different tree-dominated land classes were associated with the dietary quality of people living within them in the provinces where they were dominant. Areas of swidden/agroforestry, natural forest, timber and agricultural tree crop plantations were all associated with more frequent consumption of food groups rich in micronutrients in the areas where these were important land classes. The swidden/agroforestry land class was the landscape associated with more frequent consumption of the largest number of micronutrient rich food groups. Further research needs to be done to establish what the mechanisms are that underlie these associations. Swidden cultivation in is often viewed as a backward practice that is an impediment to food security in Indonesia and destructive of the environment. If further research corroborates that swidden farming actually results in better nutrition than the practices that replace it, Indonesian policy makers may need to

  12. Peer effects, fast food consumption and adolescent weight gain.

    2015-07-01

    This paper aims at opening the black box of peer effects in adolescent weight gain. Using Add Health data on secondary schools in the U.S., we investigate whether these effects partly flow through the eating habits channel. Adolescents are assumed to interact through a friendship social network. We propose a two-equation model. The first equation provides a social interaction model of fast food consumption. To estimate this equation we use a quasi maximum likelihood approach that allows us to control for common environment at the network level and to solve the simultaneity (reflection) problem. Our second equation is a panel dynamic weight production function relating an individual's Body Mass Index z-score (zBMI) to his fast food consumption and his lagged zBMI, and allowing for irregular intervals in the data. Results show that there are positive but small peer effects in fast food consumption among adolescents belonging to a same friendship school network. Based on our preferred specification, the estimated social multiplier is 1.15. Our results also suggest that, in the long run, an extra day of weekly fast food restaurant visits increases zBMI by 4.45% when ignoring peer effects and by 5.11%, when they are taken into account.

    We investigated water-related resource use, emissions and ecosystem impacts of food consumed in Switzerland. To do so, we coupled LCA methodologies on freshwater consumption, freshwater eutrophication and the consequent local and global biodiversity impacts with Swiss customs data and multiregional input-output analysis. Most of the resource use, emissions and impacts occur outside the national boundaries which illustrates the extent of environmental outsourcing facilitated by international trade. Countries that are severely affected by Swiss food consumption include Spain, the United States and Ecuador. Cocoa, coffee, and almonds stood out as products with high impacts. By identifying spatial hotspots and impactful products, awareness of policy-makers as well as individual consumers can be raised and efforts of detailed assessments can be streamlined. However, political and economic constraints and the resistance by individual consumers limit the high potential of changes in diets and trade relations to decrease the environmental impacts of food.

    Purpose This study identifies trends in the availability of various food choices in United States’ middle and high schools from 2004–2007, and examines the potential associations between such food availability and students’ self-reported eating habits and BMI-related outcomes. Methods Data are based on nationally representative samples of 78,442 students in 684 secondary schools surveyed from 2004 to 2007 as part of the Youth, Education, and Society (YES) study and the Monitoring the Future (MTF) study. In the YES study, school administrators and food service managers completed self-administered questionnaires on their school’s food environment. In the MTF study, students in the same schools completed self-administered questionnaires, providing data used to construct BMI and food consumption measures. Results Overall, there was a decrease in the availability of regular sugar/fat food items in both middle and high schools, and some indication of an increase high school availability of reduced fat food items through school lunch or a la carte. Some minimal evidence was found for relationships between the school food environment and student BMI-related outcomes and food consumption measures. Conclusions United States secondary schools are making progress in the types of foods offered to students, with food items of lower nutritional value becoming less prevalent in recent years. Continued monitoring of food environment trends may help clarify if and how such factors relate to youth health outcomes. PMID:19699436

    The current study used a modified implicit association test (IAT) to change implicit evaluations of unhealthy snack food and tested its effects on subsequent consumption. Furthermore, we investigated whether these effects were moderated by inhibitory self-control. A sample of 148 women (17-25 years) motivated to manage weight through healthy eating completed an IAT intervention, and pre- and post-intervention IATs assessing implicit evaluations of unhealthy food. The intervention IAT trained participants to pair unhealthy food stimuli with either positive or negative stimuli. A task disguised as a taste-test was used to assess consumption of unhealthy snack foods. Inhibitory self-control was measured using a self-report scale. As predicted, the implicit evaluation of unhealthy food became more negative from pre- to post-training among participants in the food negative pairing condition; however, there was no corresponding change in the food positive pairing condition. The effect of the training on snack consumption was moderated by inhibitory self-control with only participants low in inhibitory self-control having lower snack intake following the food negative training. This finding is consistent with dual-process models of behaviour which predict that self-control capacity renders impulses less influential on behaviour. Furthermore, it suggests that an intervention that retrains implicit food evaluations could be effective at reducing unhealthy eating, particularly among those with low inhibitory self-control.

    Current advertising messages for food products deserve special attention, since they indicate that the media has played a central role in shaping new eating habits. The food industry, seeking to serve a new customer segment (increasingly preoccupied with health and physical well-being), and with a specific interest in this promising market, has intensified its marketing strategies for stimulating consumption of diet and light food products. This study analyzed 20 food advertisements published from June to October 2006 in Brazilian magazines and newspapers with nationwide circulation. The following elements were analyzed in the advertisements: the advertiser; the audience; the language; and the message. It was seen that the advertising message mainly targeted women, proposing guilt-free consumption, promising a combination of esthetics and health. In order to enhance their product, several advertisements omitted relevant nutritional information while others promoted hazardous combinations with pharmaceutical products, and still others induced the target public to replace regular meals with their product. The results signal the need to broaden the discussion on the strategies for food advertising, as the citizen's right to information and health cannot be subjugated to market values. PMID:21987330

    Soda consumption may contribute to weight gain over time. Objective data were used to determine whether soda consumption predicts weight gain or changes in glucose regulation over time. Subjects without diabetes (128 men, 75 women; mean age 34.3±8.9 years; mean body mass index 32.5±7.4; mean percentage body fat 31.6%±8.6%) self-selected their food from an ad libitum vending machine system for 3 days. Mean daily energy intake was calculated from food weight. Energy consumed from soda was recorded as were food choices that were low in fat (<20% of calories from fat) or high in simple sugars (>30%). Food choices were expressed as percentage of daily energy intake. A subset of 85 subjects had measurement of follow-up weights and oral glucose tolerance (57 men, 28 women; mean follow-up time=2.5±2.1 years, range 6 months to 9.9 years). Energy consumed from soda was negatively related to age (r=-0.27, P=0.0001) and choosing low-fat foods (r=-0.35, P<0.0001), but positively associated with choosing solid foods high in simple sugars (r=0.45, P<0.0001) and overall average daily energy intake (r=0.46, P<0.0001). Energy intake from food alone did not differ between individuals who did and did not consume beverage calories (P=0.11). Total daily energy intake had no relationship with change in weight (P=0.29) or change in glucose regulation (P=0.38) over time. However, energy consumed from soda correlated with change in weight (r=0.21, P=0.04). This relationship was unchanged after adjusting for follow-up time and initial weight. Soda consumption is a marker for excess energy consumption and is associated with weight gain. PMID:24321742

    A cross-sectional study was conducted in 29 villages of Khamkeuth District in Bolikhamxay Province in the Lao PDR during March to May 2013. The study aimed to determine the characteristics associated with rodent consumption and related behaviors among different ethnic groups, ages, and genders. Five-hundred-eighty-four (584) males and females from 18-50 years of age participated in this study. Half of them were Hmong (292, 50%) while 152 respondents were Lao-Tai (26%) or other ethnic groups (140, 24%). Most of the respondents (79.5%) had farming as their main occupation. Prevalences of the studied outcomes were high: 39.9 for hunting or capturing rodents in the previous year, 77.7% for preparing rodents as food, and 86.3% for rodent consumption. Multivariable logistic regression analysis showed that likelihood of these types of rodent contact was more consistently associated with behavioral factors (gathering things from the forest and elsewhere, cultivation-related activities, and taking measures to prevent rodent-borne disease) than with socio-demographic, environmental, or cultural factors. The strongest associations were observed for gathering things; these associations were consistently positive and statistically significant. Although this study did not directly assess rodent-borne zoonosis risk, we believe that study findings raise concern that such risk may be substantial in the study area and other similar areas. Further epidemiological studies on the association between rodent-borne disease infection and rodent hunting, preparation for food, and consumption are recommended. Moreover, further studies are needed on the association between these potential exposure factors (i.e., rodent hunting, preparation for food, and consumption) and rodent-borne infections, especially among ethnic groups like the Hmong in Lao PDR and those in neighboring countries with similar socio-demographic, environmental, behavioral and cultural contexts.

Over 3,000 compounds are being added to processed food, with numerous effects on the food: to add color, stabilize, texturize, preserve, sweeten, thicken, add flavor, soften, emulsify, and so forth. According to World Health Organization, governments have lately focused on legislation to reduce such ingredients or compounds in manufactured foods as they may have side effects causing health risks such as heart disease, cancer, diabetes, allergens, and obesity. By supervising what and how much to eat as well as what not to eat, we can maximize a patient's life quality through avoidance of unhealthy ingredients. Smart e-health systems with powerful knowledge bases can provide suggestions of appropriate foods to individuals. Next-generation smart knowledgebase systems will not only include traditional syntactic-based search, which limits the utility of the search results, but will also provide semantics for rich searching. In this paper, performance of concept matching of food ingredients is semantic-based, meaning that it runs its own semantic based rule set to infer meaningful results through the proposed Ontology-Driven Mobile Safe Food Consumption System (FoodWiki).

    The purpose of this report is to provide a bibliography for the Native American tribe participants in the Hanford Environmental Dose Reconstruction (HEDR) Project to use. The HEDR Project's primary objective is to estimate the radiation dose that individuals could have received as a result of emissions since 1944 from the US Department of Energy's Hanford Site near Richland, Washington. Eight Native American tribes are responsible for estimating daily and seasonal consumption of traditional foods, demography, and other lifestyle factors that could have affected the radiation dose received by tribal members. This report provides a bibliography of recorded accounts that tribal researchers may use to verify their estimates. The bibliographic citations include references to information on the specific tribes, Columbia River plateau ethnobotany, infant feeding practices and milk consumption, nutritional studies and radiation, tribal economic and demographic characteristics (1940--1970), research methods, primary sources from the National Archives, regional archives, libraries, and museums.

    The geographical differences in mortality from cancer of seven sites of the digestive organs and consumption of foods in 46 of the prefectures, excluding Okinawa and their capital cities were statistically observed. The groups of foods statistically associated with cancer death are: pork, cooking oil and shochu (low class distilled spirits) for esophageal cancer; fresh fish, salted fish, vegetables and alcoholic beverages for stomach cancer; alcoholic beverages, salted or dried fish, vegetables, bread, milk, butter, margarine, ketchup, beer and fresh fish for colonic cancer; fresh fish, salted or dried fish, salt and popular grade sake for rectal cancer; pork, popular grade sake and green tea for cancer of the biliary passages; salted or dried fish, vegetables, alcoholic beverages, oil and fresh fish for pancreatic cancer; beef, poultry, eggs and vinegar for liver cancer. Further epidemiological analyses are required to find the biological causal relationships. PMID:6513019

    Separate lines of research have demonstrated the role of mood and memory in the amount of food we consume. However, no work has examined these factors in a single study and given their combined effects beyond food research, this would seem important. In this study, the interactive effect of these factors was investigated. Unrestrained female participants (n = 64) were randomly assigned to either a positive or neutral mood induction, and were subject to a lunch cue (recalling their previously eaten meal) or no lunch cue, followed by a snack taste/intake test. We found that in line with prediction that food intake was lower in the lunch cue versus no cue condition and in contrast, food intake was higher in the positive versus neutral mood condition. We also found that more food was consumed in the lunch cue/positive mood compared to lunch cue/neutral mood condition. This suggests that positive mood places additional demands on attentional resources and thereby reduces the inhibitory effect of memory on food consumption. These findings confirm that memory cue and positive mood exert opposing effects on food consumption and highlight the importance of both factors in weight control interventions. PMID:25280672

    This article analyzes food consumption in relation to levels of DDE (the principal metabolite of DDT) in the adipose tissue of 207 Mexican women residing in States with high and low exposure to DDT. Data on the women's dietary habits and childbearing history were obtained from a personal interview. Adipose tissue DDE levels were measured by gas-liquid chromatography and compared by analysis of variance (ANOVA) and multiple linear regression. Adipose tissue DDE levels increased significantly with age (p = 0.005) and residence in coastal areas (p = 0.002) and non-significantly with the consumption of onion, cauliflower, prickly pear, squash blossoms, sweet corn, broad beans, chili pepper sauce, ham, and fish. Even so, during breastfeeding there was a non-significant reduction in these levels. The findings suggest that certain foods serve as vehicles for DDE residues and confirm that breastfeeding is a mechanism for the elimination of this insecticide, which accumulates over the years in the human body.

    Mean daily intake of all foods except cereals i.e. pulses, green leafy vegetables, roots and tubers, fruits, milk and milk products, sugar and fats of Indian obese male respondents was higher than the values recommended by Indian Council of Medical Research (ICMR, 1987). The consumption of fat and sugar was 18 and 8 percent more than the recommended intake values respectively. However, their non-obese counterparts consumed significantly (P < 0.05) lower amounts of all the foods except cereals and pulses. The intake of various nutrients i.e. energy, protein, fats, beta-carotene, thiamine, riboflavin, niacin, vit B12, folacin, ascorbic acid and calcium by obese respondents was considerably higher than the recommended values (ICMR, 1990) and the control group. All the obese respondents were consuming adequate (100% and above) amounts of energy, protein and fats. Intake of carbohydrates was marginally adequate (75-99.9%) among 92 percent of the obese respondents whereas 8 percent were consuming adequate amount of carbohydrates. They had higher consumption of visible as well as invisible fat than the control group. PMID:11142609

    West Africa has undergone rapid economic and political changes during the last 20 years. After the failure of economic policies implemented since independence, programs for structural adjustment have strongly influenced the economy. Food problems affect each country differently. The Sahel has experienced food shortages and starvation whereas in forested countries the food supply has remained stable. Nevertheless, food policies have not succeeded in contributing to urban and rural development. The rate of urbanization in west Africa is generally low but the rate of urban population growth is particularly high, much more than the growth rates of industry and infrastructure. Although metropolitan areas are affected by poverty, they offer more hope and opportunities than rural areas. Urban markets have expanded and diversified as social differences have also increased and contributed to changes in consumption structure. Urban growth has contributed to the increase of imported food: this is indicated by both the strong dependency and the change of food habits towards western food patterns. Recently however, west African urban dwellers are still preferring local items if they are affordable. When imported products are used, they are integrated within a stable meal plan consisting of a single dish with a base and a sauce, which is typical of African food preparation. Surveys of consumption-budgets are still only available on a national scale. These can provide accurate information about food consumption patterns of families, particularly for significant trends. However, they do not provide information about the dynamics of food consumption, neither for urban areas or the individual. Now a significant proportion of individual food consumption occurs outside of the home, mainly with food provided by street vendors. This new consumption habit is a response to the urban food crisis. Consumption of street-vendor-food comprises one component but this cannot be dissociated from

    The study examined the patterns of food spending, food nutrient consumption, and nutrient deficiency profiles of households in Nigeria using a cross-sectional nationwide household survey data. Food nutrients were estimated from food expenditure data while the nutrient deficiency profiles were assessed adapting Foster et al. (1984) poverty index. The study established widespread nutritional deficiencies with low-income household cohorts bearing a greater burden of the deficiencies. Protein-protein deficiency appears to be much more prevalent in urban than rural areas. However, the deficiency of micro-nutrients seems to diffuse across urban-rural divides of the country with deficiency of calcium, vitamin A, and vitamin C appearing to be more pronounced in rural areas while phosphorous, vitamin B1, vitamin B2, and vitamin B3 deficiencies seem to be higher in urban settings. Pro-poor income growth strategies and sensitively guided urban-rural food and nutrition interventions are advocated for improved food consumption and nutritional deficiency reduction. PMID:26083997

    Background: The uterine cervix is the second most common site of cancer among Indian women.Though the human papillomavirus has been demonstrated to be a causative agent for this cancer, a variety of other risk factors are in play, such as sexual and reproductive patterns, socioeconomic, hygienic practices, and diet. The accumulated evidence suggests that cervical cancer is preventable and is highly suitable for primary prevention. The dietary intake of antioxidants and vitamins like vitamin A, carotenoids, vitamin C, folacin and tocopherol is found to have protective effects against cancer of the cervix. Dietary data regarding cervical cancer are still scanty. Objective: The present study was therefore undertaken to study the dietary pattern among uterine cervical cancer patients and normal controls. Materials and Methods: A total of 60 consecutive patients and 60 controls were enrolled from a referral hospital during the year 2004. A schedule inclusive of the food frequency pattern and 24-h dietary recall along with the general information was administered to all the enrolled subjects to describe findings on the food consumption pattern along with other important factors. Results: The mean intake of energy, protein, vitamins, etc., between the cases and controls was not significantly different except for the vitamin C level. Serum vitamin E was found to have lower average in patients as compared to controls. The nutrient intake of cervical cancer patients and controls was grossly deficient in the socioeconomic group studied. With regard to the macronutrient intake, calorie and protein intakes showed a deficit of around 50% when compared to RDA. Conclusion: The food consumption profile was not significantly different between cervical cancer patients and normal controls. PMID:20596306

    An increasing number of people are consuming raw unpasteurized milk. Enhanced nutritional qualities, taste, and health benefits have all been advocated as reasons for increased interest in raw milk consumption. However, science-based data to substantiate these claims are limited. People continue to consume raw milk even though numerous epidemiological studies have shown clearly that raw milk can be contaminated by a variety of pathogens, some of which are associated with human illness and disease. Several documented milkborne disease outbreaks occurred from 2000-2008 and were traced back to consumption of raw unpasteurized milk. Numerous people were found to have infections, some were hospitalized, and a few died. In the majority of these outbreaks, the organism associated with the milkborne outbreak was isolated from the implicated product(s) or from subsequent products made at the suspected dairy or source. In contrast, fewer milkborne disease outbreaks were associated with consumption of pasteurized milk during this same time period. Twenty nine states allow the sale of raw milk by some means. Direct purchase, cow-share or leasing programs, and the sale of raw milk as pet food have been used as means for consumers to obtain raw milk. Where raw milk is offered for sale, strategies to reduce risks associated with raw milk and products made from raw milk are needed. Developing uniform regulations including microbial standards for raw milk to be sold for human consumption, labeling of raw milk, improving sanitation during milking, and enhancing and targeting educational efforts are potential approaches to this issue. Development of pre- and postharvest control measures to effectively reduce contamination is critical to the control of pathogens in raw milk. One sure way to prevent raw milk-associated foodborne illness is for consumers to refrain from drinking raw milk and from consuming dairy products manufactured using raw milk. PMID:19737059

  13. Lifestyle segmentation of US food shoppers to examine organic and local food consumption.

    PubMed

    2011-08-01

    The food related lifestyle (FRL) model, widely used on European data, is applied to US data using a modified survey instrument to examine organic and local food consumption. Since empirical studies indicate these shoppers are motivated by environmental and health concerns and limited by access, the conceptual framework employs an environmental behavior model, Attitude Behavior Context (ABC), which is consistent with means-end chain theory, the Health Belief (HB) model, and the FRL model. ABC theory incorporates contextual factors that may limit consumers' ability to act on their intentions. US food shopper data was collected in 2003 (n=956) utilizing an instrument with variables adapted from the FRL, ABC, and HB models. Cluster analysis segmented food shoppers into four FRL groups: rational, adventurous, careless, and a fourth segment that had some characteristics of both conservative and uninvolved consumers. The segments exhibited significant differences in organic and local food consumption. These were correlated with consumers' environmental concerns, knowledge and practices, health concerns and practices, as well as some demographic characteristics (race, gender, age, education), income, and variables that measured access to these foods. Implications for marketing and public policy strategies to promote organic and local foods include: emphasizing taste, nutrition, value, children, and enjoyment of cooking for rational consumers; and emphasizing health, fitness, and freshness, and providing ethnic foods for adventurous consumers. While both careless and conservative/uninvolved consumers valued convenience, the former tended to be in the highest income group, while the latter were in the lowest, were more likely to be either in the youngest or oldest age groups, and were very concerned about food safety and health.

    The effect of the built environment on diet (and ensuing health outcomes) is less understood than the effect of diet on obesity. Natural experiments are increasingly advocated in place of cross-sectional studies unable to suggest causality. The central research question of this paper, therefore, asks whether a neighborhood-level food retail intervention will affect dietary habits or food security. The intervention did not have a significant impact on fruit and vegetable consumption, and the intervention population actually purchased prepared meals more frequently. More problematic, only 8% of respondents overall regularly consumed enough fruits and vegetables, and 34% were food insecure. Further complicating this public health issue, the new grocery store closed after 17 months of operation. Results indicate that geographic access to food is only one element of malnutrition, and that multi-pronged dietary interventions may be more effective. The economic failure of the store also suggests the importance of non-retail interventions to combat malnutrition. PMID:23921626

    Sedentary behavior has progressed with modern society, generating very low levels of energy expenditure and subsequent body weight disorders (obesity). There is also evidence that the absence of physical activity associated with short sleep time and watching television or playing video games leads to poor eating habits and favors high-energy intake. These findings have generally been reported in adults, with a few studies including data on children and adolescents. This brief review summarizes the current literature regarding the impact of such activities on food consumption and eating behavior in children and adolescents. There appears to be an uncoupling effect dissociating these activities from the sensation of hunger and thus energy intake. Children and adolescents seem to increase their energy intake during and after such activities without any alteration of their subjective appetite. In addition to considering the impact of sedentary behavior and physical activity level, future public health recommendations should also focus on associated nutritional adaptations (energy balance).

Methods Data were from 45,241 adult participants in the National Health and Nutrition Survey 2006, a nationally-representative, cross-sectional survey of Mexican households. Descriptive statistics and multivariable linear and logistic regression were used to assess the relationship between location of residence, educational attainment, socioeconomic status and the following: 1) expenditure on all food and at restaurants, and 2) frequency of consumption of comida corrida/restaurant food and street food. Results Food expenditure and consumption of food prepared away from home were positively associated with socioeconomic status, educational attainment, and urban vs. rural residence (p<0.001 for all relationships in bivariate analyses). Conclusions Consumption of food prepared outside of the home may be an important part of the diet among urban Mexican adults and those with high socioeconomic status and educational attainment.

We employ a nationally-representative sample from the Early Childhood Longitudinal Survey-Kindergarten Cohort (ECLS-K) and the Nielsen Company data on spot television advertising of cereals, fast food restaurants and soft drinks to children across the top 55 designated-market areas to estimate the relation between exposure to food advertising on television and children's food consumption and body weight. Our results suggest that soft drink and fast food television advertising is associated with increased consumption of soft drinks and fast food among elementary school children (Grade 5). Exposure to 100 incremental TV ads for sugar-sweetened carbonated soft drinks during 2002-2004 was associated with a 9.4% rise in children's consumption of soft drinks in 2004. The same increase in exposure to fast food advertising was associated with a 1.1% rise in children's consumption of fast food. There was no detectable link between advertising exposure and average body weight, but fast food advertising was significantly associated with body mass index for overweight and obese children (≥85th BMI percentile), revealing detectable effects for a vulnerable group of children. Exposure to advertising for calorie-dense nutrient-poor foods may increase overall consumption of unhealthy food categories. PMID:21439918

    The authors examined associations among fast-food consumption, diet, and neighborhood fast-food exposure by using 2000-2002 Multi-Ethnic Study of Atherosclerosis data. US participants (n = 5,633; aged 45-84 years) reported usual fast-food consumption (never, <1 time/week, or > or =1 times/week) and consumption near home (yes/no). Healthy diet was defined as scoring in the top quintile of the Alternate Healthy Eating Index or bottom quintile of a Western-type dietary pattern. Neighborhood fast-food exposure was measured by densities of fast-food outlets, participant report, and informant report. Separate logistic regression models were used to examine associations of fast-food consumption and diet; fast-food exposure and consumption near home; and fast-food exposure and diet adjusted for site, age, sex, race/ethnicity, education, and income. Those never eating fast food had a 2-3-times higher odds of having a healthy diet versus those eating fast food > or =1 times/week, depending on the dietary measure. For every standard deviation increase in fast-food exposure, the odds of consuming fast food near home increased 11%-61% and the odds of a healthy diet decreased 3%-17%, depending on the model. Results show that fast-food consumption and neighborhood fast-food exposure are associated with poorer diet. Interventions that reduce exposure to fast food and/or promote individual behavior change may be helpful. PMID:19429879

    Fast food consumption is a dietary factor associated with higher prevalence of childhood obesity in the United States. The association between food prices and consumption of fast food among 5th and 8th graders was examined using individual-level random effects models utilizing consumption data from the Early Childhood Longitudinal Study, Kindergarten Class of 1998-99 (ECLS-K), price data from American Chamber of Commerce Researchers Association (ACCRA), and contextual outlet density data from Dun and Bradstreet (D&B). The results found that contextual factors including the price of fast food, median household income, and fast food restaurant outlet densities were significantly associated with fast food consumption patterns among this age group. Overall, a 10% increase in the price of fast food was associated with 5.7% lower frequency of weekly fast food consumption. These results suggest that public health policy pricing instruments such as taxes may be effective in reducing consumption of energy-dense foods and possibly reducing the prevalence of overweight and obesity among US children and young adolescents.

    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. PMID:24630940

    With the rapid urbanization, city plays a more and more significant role in the carbon cycle of urban ecosystem. The contribution of household food carbon consumption to urban carbon cycle has become increasingly important, and has been the hot issues of the urban carbon cycle study. We analyzed the dynamics of the food carbon consumption in Xiamen City from 1988 to 2010, evaluated and forecasted the trends of food carbon consumption and its environmental load. The results showed that, from 1988 to 2010, per capita food consumption and per capita food carbon consumption declined by 6% and 25%, respectively. However, due to the rapid growth of population, the total food consumption and total food carbon consumption increased by 116% and 70%, respectively. The rising of total food carbon consumption led to the increasing environmental load of food carbon. The environmental load of food carbon increased from 98 800 t to 166 200 t, particularly there is a dramatic increase of carbon input into soil in recent years. From 2011 to 2024, total food carbon consumption and environmental load will continue to rise and then decline in 2025. Per capita food carbon consumption will decline continuously from 2011. The analysis of household food consumption showed that per household food carbon consumption was affected by household income, food cost and household persons. High food carbon consumption household usually had in average three persons eating at home, spent in average 3 125 yuan x month(-1) on food, the per household food carbon consumption was 1 134.91 kg,and the per capita food carbon consumption was 378.30 kg. Per capita food carbon consumption of high-consumption family was 4.84 times higher than that of low-consumption family. PMID:23798154

    A Total Diet Study (TDS) consists of selecting, collecting and analysing commonly consumed foods to obtain concentration data of different chemical compounds in foods as eaten. A TDS food list summarises the most consumed foods and represents the dietary habits of the general population of the country under study. The work reported here investigated whether TDS food lists that were initially designed for the whole population of the country under study also sufficiently cover the dietary pattern of specific subpopulations that are extra vulnerable for certain contaminants. The work was performed using data of three European countries: the Czech Republic, France and the UK. Each national food consumption database was combined with the corresponding national TDS food list (containing 336, 212 and 119 food items for the Czech Republic, France and the UK, respectively). The data were aggregated on the highest level of hierarchy of FoodEx-1, a pan-European food classification system, including 20 main FoodEx-1 groups. For the group 'milk and dairy products', the coverage of the consumption by the food list was investigated for more refined subgroups. For each food group or subgroup and country, the average percentage of coverage of the diet by the national TDS food list was calculated for different subpopulations, including children versus adults, women versus men, vegetarians versus non-vegetarians, and women of child-bearing age versus older women. The average diet of the different subpopulations was sufficiently covered by the food list of the Czech Republic and France. For the UK the average coverage was low due to a different food-coding approach and because food lists were not derived directly from national food consumption data. At the level of the 20 main food groups, differences between the subpopulations with respect to the average coverage of consumption by the TDS food list were minimal. The differences were more pronounced when looking in detail at the

    Does contextual information about disgust influence children's food consumption and subjective experience of taste? Three- to eight-year-old children (N = 60) were presented with two identical foods, yet children were led to believe that one food had been contaminated by sneezing and licking, while the other was clean. When given the opportunity to eat the foods, 5- to 8-year-old children consumed more clean food and rated the clean food's taste more positively; younger children did not distinguish between the foods. The relation between contamination and subjective taste held even among children who ate both foods and had direct evidence that they were identical. These data indicate that children's consumption behavior and food preferences are influenced by information external to foods themselves. PMID:25558024

    Studies show that a number of forest foods consumed in Cameroon are highly nutritious and rich in health boosting bioactive compounds. This study assessed the knowledge and perceptions towards the nutritional and health promoting properties of forest foods among forest dependent communities. The relationship between knowledge, perceptions and socio-demographic attributes on consumption of forest foods was also determined. A total of 279 females in charge of decision making with respect to food preparation were randomly selected from 12 villages in southern and eastern Cameroon and interviewed using researcher administered questionnaires. Multivariate logistic regression analysis was used to identify the factors affecting consumption of forest foods. Baillonella toxisperma (98%) and Irvingia gabonesis (81%) were the most known nutrient rich forest foods by the respondents. About 31% of the respondents were aware of the nutritional value and health benefits of forest foods. About 10%-61% of the respondents expressed positive attitudes to questions related with health benefits of specific forest foods. Consumption of forest foods was found to be higher among polygamous families and also positively related to length of stay in the forest area and age of respondent with consumption of forest foods. Education had an inverse relationship with use of forest foods. Knowledge and positive attitude towards the nutritional value of forest foods were also found to positively influence consumption of forest foods. Since knowledge was found to influence attitude and consumption, there is need to invest in awareness campaigns to strengthen the current knowledge levels among the study population. This should positively influence the attitudes and perceptions towards increased consumption of forest foods. PMID:26686583

    Objective The objective of this study is to examine the relationship between residential exposure to fast-food entrées, using two measures of potential spatial access: proximity (distance to the nearest location) and coverage (number of different locations), and weekly consumption of fast-food meals. Methods Traditional fast-food restaurants and non-traditional fast-food outlets, such as convenience stores, supermarkets, and grocery stores, from the 2006 Brazos Valley Food Environment Project were linked with individual participants (n = 1409) who completed the nutrition module in the 2006 Brazos Valley Community Health Assessment. Results Increased age, poverty, increased distance to the nearest fast food, and increased number of different traditional fast-food restaurants, non-traditional fast-food outlets, or fast-food opportunities were associated with less frequent weekly consumption of fast-food meals. The interaction of gender and proximity (distance) or coverage (number) indicated that the association of proximity to or coverage of fast-food locations on fast-food consumption was greater among women and opposite of independent effects. Conclusions Results provide impetus for identifying and understanding the complex relationship between access to all fast-food opportunities, rather than to traditional fast-food restaurants alone, and fast-food consumption. The results indicate the importance of further examining the complex interaction of gender and distance in rural areas and particularly in fast-food consumption. Furthermore, this study emphasizes the need for health promotion and policy efforts to consider all sources of fast-food as part of promoting healthful food choices. PMID:21599955

    In utero exposure to mercury and lead has been linked to various adverse health effects related to growth and development. However, there was no evidence on the relationship between food consumption during pregnancy and mercury or lead level in cord blood. Therefore we measured mercury and lead levels in bloods, urines, and cord bloods obtained from 302 pregnant women and estimated relationships between food consumption during pregnancy and mercury or lead level in cord blood to identify perinatal mercury and lead exposures originated from foods during pregnancy. Relationship between food consumption and mercury or lead level was estimated using a generalized linear model after adjustment for body mass index (BMI), delivery experience, income, recruitment year, and other dietary factors for mercury and age, BMI, cesarean section, delivery experience, recruitment year, and other dietary factors for lead. Fish consumption was positively associated with mercury level in cord blood (p=0.0135), while cereal and vegetable consumptions were positively associated with lead level in cord blood (p=0.0517 for cereal and p=0.0504 for vegetable). Furthermore, tea consumption restrained increase of lead level in cord blood (p=0.0014). Our findings support that mercury or lead exposure in Korean pregnant women may come from frequent fish and cereal or vegetable consumption while tea consumption may decrease lead exposure in pregnant women. Therefore, careful intervention through food consumption should be considered. PMID:27135573

    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. PMID:23663212

    2011-01-01

    Background Very little is known about street food and fast food consumption patterns in South Africa despite this being a large sector of the national economy in terms of employment provided and sales of food. The objective of this study was to determine the use of street foods and fast foods purchased by South Africans living in different provinces and geographic areas. Methods A cross-sectional survey was conducted. Structured interview-administered questionnaires in 11 official languages were conducted at the participants' homes. A nationally representative sample (n = 3287) was drawn from all ethnic groups, and provinces including participants 16 years and older. Logistic regression was done to evaluate factors impacting on fast food consumption. Results Frequent (2 ≥ times/week) street food consumption ranged from 1.8% in Northern Cape to 20.6% in Limpopo; frequent (2 ≥ times/week) fast food consumption ranged between 1.5% in North West Province to 14.7% in Gauteng. The highest intake of street food was in the medium socio-economic category (14.7%) while the highest intake of fast foods was in the high socio-economic category (13.2%). Overall, fruit was the most commonly purchased street food by all ethnic groups over the previous week although this practice was highest in black participants (35.8%). Purchases of soft drinks ranged from 4.8% in whites to 16.4% in blacks and savoury snacks from 2.3% to 14.5% in whites and blacks, respectively. Consumption of fast foods and street foods were influenced by a number of socio-demographic factors including ownership of major home appliances. Frequent fast food consumers had a significantly higher dietary diversity score (4.69; p < 0.0001) while frequent street food consumers had a significantly lower score (3.81; p < 0.0001). Conclusions A large percentage of the population purchase street foods and fast foods. This is of some concern when one notes the high prevalence of soft drink consumption in terms of its

    OBJECTIVE To evaluate the consumption of ultra-processed foods, its associated factors, and its influence on nutrient intake in young adults. METHODS In 2004-2005, the individuals belonging to the Pelotas birth cohort of 1982 were identified for a home interview. A total of 4,297 individuals were interviewed and 4,202 individuals were included in the study (follow-up rate of 77.4%). Diet was assessed using a questionnaire on dietary intake and the percentage of daily caloric intake attributed to ultra-processed foods as well as the intake of macro- and micronutrients were estimated. The association between cohort characteristics and the consumption of ultra-processed foods was assessed using linear regression. Analysis of variance and Pearson’s Chi-square test were used to evaluate the association between the quintiles of the consumption of ultra-processed food, nutrient intake and adequacy of nutrient intake, respectively. RESULTS The consumption of ultra-processed foods corresponded to 51.2% of the total caloric intake. The consumption of ultra-processed foods was higher among women, individuals with higher education, and individuals who were never poor and eutrophic. The increased consumption of ultra-processed foods was positively correlated with the consumption of fat, cholesterol, sodium, iron, calcium, and calories (p < 0.001) and was negatively correlated with the consumption of carbohydrates, protein, and dietary fiber (p < 0.001). CONCLUSIONS The high consumption of ultra-processed foods and its positive correlation with the intake of sodium, cholesterol, and fats underscores the need to perform interventions aimed at decreasing the intake of this food group.

    2011-08-01

    Over the last decade, a strong upsurge in Spanish immigration has fostered a thriving ethnic food market. To examine indigenous consumer predilections toward ethnic foods, a carefully designed choice experiment is employed, with particular focus on ethnocentricity and food neo-phobia traits on potential purchase decisions. Employing a two level nested logit model, consumers choose to accept/reject ethnic foods, with a positive response met by a further series of different ethnic cuisine and consumption scenario alternatives. Bivariate tests reveal that higher ethnocentric and neo-phobic segments possess common socio-demographic characteristics, whilst neo-phobia plays a significantly stronger role in determining the probability of rejection. Further tests reveal culturally similar Mexican food as the preferred ethnic food across all consumption scenarios. Moreover, the 'restaurant' is the favoured format of consumption, whilst there is evidence of a strong association between specific ethnic food types and consumption formats. The implications of our research suggest that in the short to medium turn, price is a strong strategic variable, whilst marketing strategies must successfully isolate and exploit specific 'ethnic food/consumption scenario' mixes. Finally, stronger messages emphasizing quality and convenience factors are seen as key to bolstering the underrepresented 'home preparation' ethnic food market in Spain. PMID:21513751

    This study examined the effects of aspartame, saccharin, and sucrose on hunger and food intake. Twenty normal adults consumed a standard breakfast followed 3 h later by 200 mL of either water or a sweetened drink. One hour later, subjects' ad libitum consumption of a standardized lunch was measured. Subjects recorded self-assessments of hunger-related indices every half hour on visual analogue scales (VAS). ANOVA with repeated measures showed a significant effect of drink type on VAS scores 15 and 45 min after drinks were consumed but not for other times or for lunch consumption. Hunger-related ratings after drink consumption were generally highest for water, lower for noncaloric sweeteners (NCSs), and lowest for sugar. Pairwise comparisons of means showed that only the ratings for sugar and water were significantly different. The results show that, under the conditions of this study, NCSs do not increase hunger or food intake. PMID:2021127

    Background As populations are ageing, more emphasis is placed on healthy ageing. Over the past decades, food consumption patterns and food availability have also changed drastically and therefore this study aimed to describe these changes in an ageing population. Subjects/Methods Food consumption of participants from the MRC National Survey on Health and Development (NSHD), a British birth cohort study, was assessed using a 5 day estimated food records at 60-64y (2006-11), 53y (1999), 43y (1989), and 36y (1982). Only those who recorded ≥ 3 days at all four time points were included in the analyses, n=989 (n=438 men and n=551 women); trends were tested using the Friedman test. Results Consumption of white bread, whole milk, fats and oils, meat and meat products, alcoholic drinks, coffee, and sugar, preserves and confectionery decreased (p<0.001) whilst consumption of wholemeal and granary bread, semi-skimmed milk, fish, and fruit and vegetables increased (p<0.001) over time. These observed changes in food consumption reflect a healthier diet, e.g. replacement of white bread by granary and wholemeal bread, lower consumption of red and processed meats, somewhat higher consumption of fish, higher consumption of vegetables, and lower consumption of coffee. This could partly be due to ageing of the cohort or compliance with dietary recommendations, facilitated by greater availability of healthier foods, such as semi-skimmed milk and wholegrain bread, in the UK. Conclusions The changes in food consumption in this British birth cohort over the past three decades are encouraging and reflect a healthier diet in the later years. PMID:25351642

    OBJECTIVE: To perform a review of studies of food consumption and nutritional adaptation in Brazilian infants pointing the main findings and limitations of these studies. DATA SOURCE: The articles were selected from Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs) (Latin-American and Caribbean Literature in Health Sciences), Scientific Electronic Library Online (SciELO) and Science Direct in Portuguese and in English. The descriptors were: ''food consumption'', ''nutritional requirements'', ''infant nutrition'' and ''child''. The articles selected were read by two evaluators that decided upon their inclusion. The following were excluded: studies about children with pathologies; studies that approached only food practices or those adaptation of the food groups or the food offert; and studies that did not utilize the Dietary Reference Intakes (DRI). DATA SYNTHESIS: Were selected 16 studies published between 2003 and 2013. In the evaluation of the energy consumption, four studies presented energetic consumption above the individual necessities. The prevalence of micronutrients inadequacy ranged from 0.4% to 65% for iron, from 20% to 59.5% for vitamin A, from 20% to 99.4% for zinc, from 12.6% to 48.9% for calcium and from 9.6% 96.6% for vitamin C. CONCLUSIONS: The food consumption of Brazilian infants is characterized by high frequencies of inadequacy of micronutrients consumption, mainly iron, vitamin A and zinc. These inadequacies do not exist only as deficiencies, but also as excesses, as noted for energetic consumption. PMID:25935607

    Objectives We studied the association and agreement between questionnaire data and biomarkers of marine food among Greenland Inuit. Design Cross sectional study. Methods The study population comprised 2,224 Inuit, age 18+ (43% men); data collected 2005–2008 in Greenland. Using a food frequency questionnaire (FFQ), we calculated consumption of seal, whale, and fish (g/day) and as meals/month, intake of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), total N3, and mercury. We measured erythrocyte membrane fatty acids (FA) and whole blood mercury (Hg). Associations were assessed by Pearson correlation and agreement between the 2 methods was assessed by Bland–Altman plots depicting mean difference between the methods. Using multiple linear regressions, the associations were studied between whole blood mercury, erythrocyte FA and frequency or gram per day of seal, whale, and fish. Results Partial correlations ranged from r=0.16, p<0.0001 (DHA) to r=0.56, p<0.0001 (mercury). The best fitted lines were found for mercury and DHA. Mean difference was negative for mercury but positive for all the FA biomarkers. In a multiple logistic regression analysis, the best association was found between whole blood mercury and seal consumption, both as frequency in meals and actual intake gram per day: β=1.07 µg (95% CI: 1.06; 1.08) and β=1.04 µg (95% CI: 1.03; 1.04), respectively. Conclusion Mercury showed the best correlation and agreement between calculated and measured values. Calculated actual intake in gram per day and frequency of meals showed similar associations with whole blood mercury and erythrocyte membrane FAs. PMID:22663940

    Food consumption and preferences may be shaped by exposure to stressful environments during sensitive periods in development, and even small changes in consumption can have important effects on long term health. Adolescence is increasingly recognized as a sensitive period, in which adverse experiences can alter development, but the specific programming effects that may occur during adolescence remain incompletely understood. The current study seeks to explore the effects of stress during late adolescence on consumption of a palatable, high-fat, high-sugar food in adulthood—under basal conditions, as well following acute stress. Male Long-Evans rats were exposed to a regimen of variable stress for seven days in late adolescence (PND 45–51). During the stress regimen, stressed animals gained significantly less weight than control animals, but weight in adulthood was unaffected by adolescent stress. Palatable food consumption differed between experimental groups, and the direction of effect depended on context; stressed rats ate significantly more palatable food than controls upon first exposure, but ate less following an acute stressor. Leptin levels and exploratory behaviors did not differ between stressed and non-stressed groups, suggesting that other factors regulate preference for a palatable food. Altered food consumption following adolescent stress suggests that rats remain sensitive to stress during late adolescence, and that adult feeding behavior may be affected by previous adverse experiences. Such programming effects highlight adolescence as a period of plasticity, with the potential to shape long term food consumption patterns and preferences. PMID:26872268

    This study applied and extended the Theory of Planned Behaviour (TPB; Ajzen, 1988) in an examination of the variables influencing fast-food consumption in an Australian sample. Four hundred and four participants responded to items measuring TPB constructs and retrospective and prospective measures of fast-food consumption. Additional independent variables included: Consideration of Future Consequences (Strathman, Gleicher, Boninger, & Edwards, 1994), Fear of Negative Evaluation (Leary, 1983), and Self-Identification as a Healthy Eater Scale (Armitage & Conner, 1999a). Structural Equation Modeling (SEM) was used to examine predictors of consumption. SEM indicated that the TPB successfully predicted fast-food consumption. Factor analyses assisted in the definition of constructs that underlay attitudes towards fast foods. These constructs were included in an 'extended' TPB model which then provided a richer source of information regarding the nature of the variables influencing fast-food consumption. Findings suggest that fast-food consumption is influenced by specific referent groups as well as a general demand for meals that are tasty, satisfying, and convenient. These factors reflect immediate needs and appear to override concerns about longer-term health risks associated with fast food. Results are discussed in the context of possible applications.

    We tested a theoretical model concerning the role of attentional bias and negative affect in food consumption that offers important advances. We hypothesized that the effects of negative affect manipulations on food consumption vary as a function of trait levels of negative urgency (NU; tendency to act impulsively when distressed), and attentional bias and that the roles of emotional arousal and negative emotional valence differ and should be studied separately. 190 undergraduate women were randomly assigned to either an anger or neutral mood condition. Women in both conditions completed the Food Stroop, in which the presentation of food and neutral words were counterbalanced. After the task, participants were given the opportunity to eat mandarin oranges and/or chocolate candy while the experimenter was out of the room. The type and quantity of food consumed was counted after the participant departed. As hypothesized, the roles of emotional arousal and valence differed and the effect of the induced emotion was moderated by NU. Women high in NU who experienced emotional arousal were more likely to eat candy and consumed more candy than other women. Emotional valence had no effect on candy consumption. Neither increases in emotional arousal or emotional valence influenced attentional bias to food cues. Attentional bias was also unrelated to food consumption. The impact of negative mood inductions on palatable food consumption appears to operate through emotional arousal and not negative emotional valence, and it may operate primarily for women high in NU.

    The workshop "Food-consumption surveys in developing countries: Future challenges," held in Chiang Rai, Thailand, January 25--26, 2003, brought together 30 nutritionists and food safety experts from 10 Southeast Asian countries as well as from countries outside the region. It provided a forum for sharing information and experiences relating to food-consumption survey methodology. It enabled detailed discussions of the gathering of food-consumption data in developing countries for purposes of nutrition assessment, exposure assessment, and studies of diet-disease relationships. The workshop participants emphasized the need to obtain the support of policy and decision makers to establish a mechanism for conducting regular coordinated food-consumption surveys to meet these needs. The participants emphasized the importance of identifying all relevant stakeholders and involving them in the planning and conduct of these surveys. A number of technical issues related to food-con.sumption surveys were discussed, including food-intake methodologies. It was felt that surveys on individuals are preferred, and a combination of 24-hour recall and food-frequency questionnaire would most likely provide the required data. The workshop emphasized the need to develop, maintain, and update databases at the national and regional levels for nutrients and non-nutrients as well as contaminants and food additives. To ensure that surveys are conducted regularly and professionally, the importance of having qualified and trained personnel was emphasized. Several issues related to reports of food-consumption data were discussed, including timely reporting, effective dissemination, and appropriate usage. The participants unanimously recommended the organization of further technical meetings or workshops to follow up on recommended activities and enable continuing regional collaboration on food-consumption surveys.

    Soft drink and fast food are energy dense foodstuffs that are heavily marketed to adolescents, and are likely to be important in terms of risk of obesity. This study sought to examine the influences on soft drink and fast food consumption among adolescents as part of a cross-sectional survey of 2,719 adolescents (aged 11-16) from 93 randomly selected schools in New South Wales, Australia. Students provided information on soft drink and fast food consumption, and responded to statements examining influences over consumption. Over half of the boys and more than one third of the girls reported drinking soft drink daily, and consumption peaked in Grade 8 students. A quarter of students reported choosing soft drinks instead of water or milk, and around 40% agreed that soft drink was usually available in their homes. Availability in the home and drinking soft drinks with meals was most strongly associated with consumption in all age groups. Fast food consumption was higher among boys than girls in all age groups. Convenience and value for money yielded the strongest associations with fast food consumption in boys, while preferring fast food to meals at home and preferring to "upsize" meals were most strongly associated with consumption in girls. Interventions to reduce consumption of soft drinks should target availability in both the home and school environment by removing soft drinks and replacing them with more nutritive beverages. Fast food outlets should be encouraged to provide a greater range of healthy and competitively priced options in reasonable portions. PMID:19786394

    Food is evaluated for various attributes. One of the key food evaluation domains is hedonicity. As food is consumed, its hedonic valence decreases (due to prolonged sensory stimulation) and hedonic habituation results. The aim of the present study was to investigate changes in food pleasantness ratings during consumption of a simple food by individuals without olfactory experience with food as compared to normosmics. 15 congenital anosmics and 15 normosmic controls were each presented with ten 10 g banana slices. Each was visually inspected, then smelled and chewed for ten seconds and subsequently rated for hedonicity on a 21-point scale. There was a significant difference in pleasantness ratings between congenital anosmics and controls (F(1, 26) = 6.71, p = .02) with the anosmics exhibiting higher ratings than the controls, a significant main repeated-measures effect on the ratings (F(1.85, 48) = 12.15, p<.001), which showed a decreasing trend over the course of consumption, as well as a significant portion*group interaction (F(1.85, 48) = 3.54, p = .04), with the anosmic participants experiencing a less pronounced decline. The results of the present explorative study suggest that over the course of consumption of a simple food, congenitally anosmic individuals experience differential patterns of appreciation of food as compared to normosmics. In this particular case, the decrease of hedonic valence was less pronounced in congenital anosmics. PMID:22529901

    In the consumer phase of a typical quantitative microbiological risk assessment (QMRA), mathematical equations identify data gaps. To acquire useful data we designed a food consumption and food handling survey (2,226 respondents) for QMRA applications that is especially aimed at obtaining quantitative data. For a broad spectrum of food products, the survey covered the following topics: processing status at retail, consumer storage, preparation, and consumption. Questions were designed to facilitate distribution fitting. In the statistical analysis, special attention was given to the selection of the most adequate distribution to describe the data. Bootstrap procedures were used to describe uncertainty. The final result was a coherent quantitative consumer phase food survey and parameter estimates for food handling and consumption practices in The Netherlands, including variation over individuals and uncertainty estimates.

    To identify barriers to traditional food consumption and factors that facilitate it among the Cree community of Mistissini, a series of four focus groups was conducted with a total of twenty-three people. Two ecological models were created, one for facilitating factors and a second for obstacles, illustrating the role of numerous interconnected influences of traditional food consumption. Environmental impact project, laws and regulation, local businesses, traditional knowledge, youth influence, employment status, and nonconvenience of traditional food were named among numerous factors influencing traditional food consumption. The findings of this study can be used by political and public health organizations to promote traditional food where more emphasis should be invested in community and environmental strategies.

    Food consumption surveys are performed in many countries. Comparison of results from those surveys across nations is difficult because of differences in methodological approaches. While consensus about the preferred methodology associated with national food consumption surveys is increasing, no inventory of methodological aspects across continents is available. The aims of the present review are (1) to develop a framework of key methodological elements related to national food consumption surveys, (2) to create an inventory of these properties of surveys performed in the continents North-America, South-America, Asia and Australasia, and (3) to discuss and compare these methodological properties cross-continentally. A literature search was performed using a fixed set of search terms in different databases. The inventory was completed with all accessible information from all retrieved publications and corresponding authors were requested to provide additional information where missing. Surveys from ten individual countries, originating from four continents are listed in the inventory. The results are presented according to six major aspects of food consumption surveys. The most common dietary intake assessment method used in food consumption surveys worldwide is the 24-HDR (24 h dietary recall), occasionally administered repeatedly, mostly using interview software. Only three countries have incorporated their national food consumption surveys into continuous national health and nutrition examination surveys. PMID:25984745

    Objective. This study was conducted to identify some factors (beliefs and norms) which are related to fast food consumption among high school students in Isfahan, Iran. We used the framework of the theory planned behavior (TPB) to predict this behavior. Subjects & Methods. Cross-sectional data were available from high school students (n = 521) who were recruited by cluster randomized sampling. All of the students completed a questionnaire assessing variables of standard TPB model including attitude, subjective norms, perceived behavior control (PBC), and the additional variables past behavior, actual behavior control (ABC). Results. The TPB variables explained 25.7% of the variance in intentions with positive attitude as the strongest (β = 0.31, P < 0.001) and subjective norms as the weakest (β = 0.29, P < 0.001) determinant. Concurrently, intentions accounted for 6% of the variance for fast food consumption. Past behavior and ABC accounted for an additional amount of 20.4% of the variance in fast food consumption. Conclusion. Overall, the present study suggests that the TPB model is useful in predicting related beliefs and norms to the fast food consumption among adolescents. Subjective norms in TPB model and past behavior in TPB model with additional variables (past behavior and actual behavior control) were the most powerful predictors of fast food consumption. Therefore, TPB model may be a useful framework for planning intervention programs to reduce fast food consumption by students. PMID:23936635

    Routine operations at the Savannah River Site (SRS) result in the release of radionuclides to the atmosphere and to the Savannah River. The resulting radiological doses to the off-site maximum individual and the 80-km population are estimated on a yearly basis. These estimates are generated using dose models prescribed in the NRC Reg. Guide 1.109 for the commercial nuclear power industry. A study of land and water usage characteristics in the region of the Savannah River Site has been conducted to determine site-specific values of the NRC dose model parameters. The study's scope included local characteristics of meat, milk, vegetable production; Savannah River recreational activities and fish harvests; meat, milk, vegetable, and seafood consumption rates; and Savannah River drinking-water populations. Average and maximum consumption rates of beef, milk, vegetables, and fish have been determined for individuals residing in the southern United States. The study suggest that many of the consumption rates provided by the NRC may not be appropriate for residents of the South. Average consumption rates are slightly higher than the defaults provided by the NRC. Maximum consumption rates, however, are typically lower than NRC values. Agricultural productivity in the SRS region was found to be quite different than NRC recommendations. Off-site doses have been predicted using both NRC and SRS parameter values to demonstrate the significance of site-specific data.

    Understanding how healthfully people think they eat compared to others has implications for their motivation to engage in dietary change and the adoption of health recommendations. Our goal was to investigate the scope, sources, and measurements of bias in comparative food consumption beliefs. Across 4 experiments, participants made direct comparisons of how their consumption compared to their peers' consumption and/or estimated their personal consumption of various foods/nutrients and the consumption by peers, allowing the measurement of indirect comparisons. Critically, the healthiness and commonness of the foods varied. When the commonness and healthiness of foods both varied, indirect comparative estimates were more affected by the healthiness of the food, suggesting a role for self-serving motivations, while direct comparisons were more affected by the commonness of the food, suggesting egocentrism as a nonmotivated source of comparative bias. When commonness did not vary, the healthiness of the foods impacted both direct and indirect comparisons, with a greater influence on indirect comparisons. These results suggest that both motivated and nonmotivated sources of bias should be taken into account when creating interventions aimed at improving eating habits and highlights the need for researchers to be sensitive to how they measure perceptions of comparative eating habits.

    Do people's perceptions that they live in a harsh environment influence their food choices? Drawing on life-history theory, we propose that cues indicating that the current environment is harsh (e.g., news about an economic crisis, the sight of people facing adversity in life) lead people to perceive that resources in the world are scarce. As a consequence, people seek and consume more filling and high-calorie foods, which they believe will sustain them for longer periods of time. Although perceptions of harshness can promote unhealthy eating, we show how this effect can be attenuated and redirected to promote healthier food choices. PMID:23302296

    BACKGROUND/OBJECTIVES The purpose of this study is to identify how level of information affected intention, using the Theory of Planned Behavior. SUBJECTS/METHODS The study was conducted survey in diverse community centers and shopping malls in Seoul, which yielded N = 209 datasets. To compare processed foods consumption behavior, we divided samples into two groups based on level of information about food additives (whether respondents felt that information on food additives was sufficient or not). We analyzed differences in attitudes toward food additives and toward purchasing processed foods, subjective norms, perceived behavioral control, and behavioral intentions to processed foods between sufficient information group and lack information group. RESULTS The results confirmed that more than 78% of respondents thought information on food additives was insufficient. However, the group who felt information was sufficient had more positive attitudes about consuming processed foods and behavioral intentions than the group who thought information was inadequate. This study found people who consider that they have sufficient information on food additives tend to have more positive attitudes toward processed foods and intention to consume processed foods. CONCLUSIONS This study suggests increasing needs for nutrition education on the appropriate use of processed foods. Designing useful nutrition education requires a good understanding of factors which influence on processed foods consumption. PMID:24944779

    Background Gestational diabetes prevalence is increasing, mostly because obesity among women of reproductive age is continuously escalating. We aimed to investigate the incidence of gestational diabetes according to the consumption of fast food in a cohort of university graduates. Methods The prospective dynamic “Seguimiento Universidad de Navarra” (SUN) cohort included data of 3,048 women initially free of diabetes or previous gestational diabetes who reported at least one pregnancy between December 1999 and March 2011. Fast food consumption was assessed through a validated 136-item semi-quantitative food frequency questionnaire. Fast food was defined as the consumption of hamburgers, sausages, and pizza. Three categories of fast food were established: low (0–3 servings/month), intermediate (>3 servings/month and ≤2 servings/week) and high (>2 servings/week). Non-conditional logistic regression models were used to adjust for potential confounders. Results We identified 159 incident cases of gestational diabetes during follow-up. After adjusting for age, baseline body mass index, total energy intake, smoking, physical activity, family history of diabetes, cardiovascular disease/hypertension at baseline, parity, adherence to Mediterranean dietary pattern, alcohol intake, fiber intake, and sugar-sweetened soft drinks consumption, fast food consumption was significantly associated with a higher risk of incident gestational diabetes, with multivariate adjusted OR of 1.31 (95% conficence interval [CI]:0.81–2.13) and 1.86 (95% CI: 1.13–3.06) for the intermediate and high categories, respectively, versus the lowest category of baseline fast food consumption (p for linear trend: 0.007). Conclusion Our results suggest that pre-pregnancy higher consumption of fast food is an independent risk factor for gestational diabetes. PMID:25215961

    Although fast food is affordable and convenient, it is also high in calories, saturated fat and sodium. The frequency of fast food intake at the time of, and after, acute myocardial infarction (AMI) is modifiable. However, patterns of fast food intake and characteristics associated with its consumption among AMI patients are unknown. We studied fast food consumption at the time of AMI and 6 months later in 2481 patients from the prospective, 24-center TRIUMPH study of AMI patients. Fast food intake was categorized as frequent (≥ weekly) vs. infrequent (< weekly). Multivariable log-binomial regression was used to identify patient characteristics associated with frequent fast food intake 6 months after AMI. At baseline, 884 patients (36%) reported frequent fast food intake, which decreased to 503 (20%) 6 months after discharge (p-value <0.001). Male sex, white race, lack of college education, current employment and dyslipidemia were independently associated with frequent fast food intake 6 months after AMI. In contrast, older patients and those who had coronary bypass surgery were less likely to eat fast food frequently. Documentation of discharge dietary counseling was not associated with 6-month fast food intake. In conclusion, fast food consumption by AMI patients declined 6 months after the index hospitalization, but certain populations, including younger patients, men, those currently working, and less educated patients were more likely to consume fast food, at least weekly, during follow-up. Novel interventions that go beyond traditional dietary counseling may be needed to address continued fast food consumption after AMI in these patients. PMID:21306695

    Infection resulting from foodborne pathogens, including Escherichia coli O157:H7, is often associated with consumption of raw or undercooked ground beef. However, little is known about the frequency of ground beef consumption in the general population. The objective of this study was to describe patterns of self-reported ground beef and pink ground beef consumption using data from the 2006 through 2007 FoodNet Population Survey. From 1 July 2006 until 30 June 2007, residents of 10 FoodNet sites were contacted by telephone and asked about foods consumed within the previous week. The survey included questions regarding consumption of ground beef patties both inside and outside the home, the consumption of pink ground beef patties and other types of ground beef inside the home, and consumption of ground beef outside the home. Of 8,543 survey respondents, 75.3% reported consuming some type of ground beef in the home. Of respondents who ate ground beef patties in the home, 18.0% reported consuming pink ground beef. Consumption of ground beef was reported most frequently among men, persons with incomes from $40,000 to $75,000 per year, and persons with a high school or college education. Ground beef consumption was least often reported in adults ≥65 years of age. Men and persons with a graduate level education most commonly reported eating pink ground beef in the home. Reported consumption of ground beef and pink ground beef did not differ by season. Ground beef is a frequently consumed food item in the United States, and rates of consumption of pink ground beef have changed little since previous studies. The high rate of consumption of beef that has not been cooked sufficiently to kill pathogens makes pasteurization of ground beef an important consideration, especially for those individuals at high risk of complications from foodborne illnesses such as hemolytic uremic syndrome.

    Nutritional recommendations call for balanced, diversified consumption of starchy foods and increased whole-grain food intake. Their efficiency may depend on sociodemographic and socioeconomic factors, for which little information is available. The aim of the present study was to investigate the relationship between sociodemographic and socioeconomic characteristics and starchy food consumption in a large general population of French adults. Dietary intake was assessed using at least six 24-h dietary records collected, during a 2-year period, from 4574 men and women aged 45-60 years who participated in the Supplémentation en VItamines Minéraux et AntioXydants cohort study in 1995-7. Compliance with the recommendation ( > or = 3 and < 6 servings/d), non-consumption of whole-grain products, variety and daily cost were compared across sociodemographic and socioeconomic categories using logistic regression and covariance analyses. About 55 % of subjects complied with the starchy food recommendation, with little variation across sociodemographic characteristics. Consumption of whole-grain products was less likely in men (P = 0.001), in subjects with a lower education level (P-trend = 0.01) and in those belonging to intermediate occupational categories (P = 0.02). The variety of starchy food intake increased with education level (P-trend = 0.0002) and was lowest for manual workers (P = 0.03). The proportion of daily food cost spent on starchy foods decreased with occupational category (P < 0.0001), and was higher in rural areas (P = 0.0004). The starchy food budget spent on potatoes decreased with the educational level (P-trend = 0.007), whereas it increased for rice and unsweetened breakfast cereals (P-trend = 0.001 for both). Public recommendations concerning starchy food variety and whole-grain intake should specifically target subjects with a lower education level and/or occupational category. PMID:19995473

    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.

    In the first experiment, two rhesus monkeys earned their entire ration of food and water during daily sessions with no provisions to ensure constant daily intakes. Two variable-interval schedules of food presentations were concurrent with one variable-interval schedule of water presentations; the maximum rate of food presentations arranged by one food schedule was varied. As the rate of food presentations was increased, the absolute level of responding on the two food schedules combined decreased, while responding on the water schedule increased. The preference for the variable food schedule compared to the other food schedule approximately matched the proportion of reinforcers obtained from it. The preference for the variable food schedule compared to the water schedule did not match, but greatly decreased, as the proportion of reinforcers from the food schedule increased. When Experiment I was replicated, with provisions to ensure constant daily intakes of food and water (Experiment II), the absolute response rates under the two food schedules combined and under the water schedule no longer changed with increases in the rate of food during the sessions. On the other hand, choice between the two food schedules remained proportional to the distribution of obtained food pellets. These results were interpreted as indicating that behavior to obtain nonsubstitutable commodities, such as food and water, is strongly controlled by the economic conditions of daily consumption, while choice between substitutable commodities is independent of these factors.

    Research has shown that subtle health claims used by food marketers influence pre-intake expectations, but no study has examined how they influence individuals' post-consumption experience of satiety after a complete meal and how this varies according to the value placed on food taste. In two experiments, we assess how labeling a pasta salad as "healthy" or "hearty" influences self-reported satiety, consumption volume, and subsequent consumption of another food. Using MANOVA, Study 1 shows that individuals who report low taste importance consume less-yet feel just as satiated-when a salad is labeled "hearty" rather than "healthy." In contrast, for individuals with higher taste importance, consumption and self-reported satiety are correlated and are both higher when a salad is labeled as "hearty" versus "healthy." Study 2 primes taste importance, rather than measuring it, and replicates these findings for consumption, but not for self-reported satiety. There was no effect on the consumption of other foods in either study. Overall, our findings add to earlier work on the impact of health labels by showing that subtle food descriptions also influence post-intake experiences of satiety, but that the direction of the effects depends on taste importance and on the selection of direct or indirect measures of satiety.

    Anthropogenic warming is caused mainly by emissions of greenhouse gases (GHGs), such as carbon dioxide, methane, and nitrous oxide, with agriculture as a main contributor for the latter 2 gases. Other parts of the food system contribute carbon dioxide emissions that emanate from the use of fossil fuels in transportation, processing, retailing, storage, and preparation. Food items differ substantially when GHG emissions are calculated from farm to table. A recent study of approximately 20 items sold in Sweden showed a span of 0.4 to 30 kg CO(2) equivalents/kg edible product. For protein-rich food, such as legumes, meat, fish, cheese, and eggs, the difference is a factor of 30 with the lowest emissions per kilogram for legumes, poultry, and eggs and the highest for beef, cheese, and pork. Large emissions for ruminants are explained mainly by methane emissions from enteric fermentation. For vegetables and fruits, emissions usually are foods rich in carbohydrates, such as potatoes, pasta, and wheat, are <1.1 kg/kg edible food. We suggest that changes in the diet toward more plant-based foods, toward meat from animals with little enteric fermentation, and toward foods processed in an energy-efficient manner offer an interesting and little explored area for mitigating climate change.

    Background Saudi Arabia has passed through lifestyle changes toward unhealthy dietary patterns such as high fast food consumption. Adolescents and young adults, particularly girls, are the main groups exposed to and affected by these adverse eating behaviors. Objective The aim of this study was to examine the trends of fast food consumption among adolescent and young adult Saudi girls living in Riyadh, and to compare between them. Design In a cross-sectional survey, 127 adolescent Saudi girls (13–18 years) and 69 young adult Saudi girls (19–29 years) were randomly recruited to participate in this study. Weight, height, waist circumference, and hip circumference were measured using standardized methods. Twenty-four-hour diet recall and a face-to-face interview food questionnaire were performed. Results Most of the participants had adequate intake of protein, riboflavin, iron, and sodium, but exhibited low intake for several other nutrients. Among study participants, 95.4% consume restaurants’ fast food and 79.1% eat fast food at least once weekly. Burgers and carbonated soft drinks were the main kinds of fast food meals and beverages usually eaten by girls. Adolescent girls who usually ate large portion sizes of fast food had significantly higher mean waist circumference and hip circumference. Participants eat fast food primarily for enjoying the delicious taste, followed by convenience. Restaurants’ hygiene and safety standards were the main concern regarding fast food for 62.2% of girls. Finally, international restaurants were preferable by participants to buy fast food compared with local restaurants (70.9% vs. 29.1%). Conclusion Our findings provide evidence on the high prevalence of fast food consumption among Saudi girls, suggesting an urgent need for community-based nutrition interventions that consider the trends of fast food consumption and targeted eating behaviors of adolescent and young adult girls.

    The aim of this study was to examine the effectiveness of various types of parental communication in modifying children's responses to television food advertising. In a combined diary-survey study among 234 parents of 4- to 12-year-old children, I investigated how different styles of advertising mediation (active vs. restrictive) and consumer communication (concept-oriented vs. socio-oriented) moderated the relation between children's advertising exposure and their consumption of advertised energy-dense food products. Interaction analysis in regression showed that active advertising mediation (i.e. explaining the purpose and nature of advertising), and socio-oriented consumer communication (i.e. emphasizing control and restrictions) significantly reduced the impact of advertising on children's food consumption. Parental restrictions of advertising exposure were only effective among younger children (<8). These results suggest that critical discussion about advertising and rule making about consumption are most effective in countering the impact of food advertising. PMID:19972665

    Background The physical environments in which adolescents reside and their access to food stores may influence their consumption of fruit and vegetables. This association could either be direct or mediated via psychosocial variables or home availability of fruit and vegetables. A greater understanding of these associations would aide the design of new interventions. The purpose of this study was to examine associations between distance to food stores and restaurants and fruit and vegetable consumption and the possible mediating role of psychosocial variables and home availability. Methods Fruit and vegetable consumption of 204 Boy Scouts was assessed by a food frequency questionnaire in 2003. Participant addresses were geo-coded and distance to different types of food stores and restaurants calculated. Fruit and vegetable preferences, home availability and self-efficacy were measured. Regression models were run with backward deletion of non-significant environmental and psychosocial variables. Mediation tests were performed. Results Residing further away from a small food store (SFS) (convenience store and drug store) was associated with increased fruit and juice and low fat vegetable consumption. Residing closer to a fast food restaurant was associated with increased high fat vegetable and fruit and juice consumption. Vegetable preferences partially mediated (26%) the relationship between low fat vegetable consumption and distance to the nearest SFS. Conclusion Distance to SFS and fast food restaurants were associated with fruit and vegetable consumption among male adolescents. Vegetable preferences partially mediated the distance to low fat vegetable relationship. More research is needed to elucidate how environmental variables impact children's dietary intake.

    Background The demographics and lifestyles of Canadians are changing, thereby influencing food choices and food preparation in the home. Although different dietary practices are associated with increased risk of foodborne illness, our ability to evaluate food consumption trends and assess risks associated with foodborne illness is limited by lack of data on current eating habits and consumer food safety practices. The objective of this study was to describe, for the first time, the food consumption patterns in a Canadian-based population from a food safety perspective, in order to establish baseline data on actual food intake of individuals. Method A cross-sectional telephone survey of 2,332 randomly selected residents of Waterloo Region, Ontario, Canada (C-EnterNet pilot site) was conducted between November 2005 and March 2006. Food intake was assessed using a 7-day dietary recall method. Results Certain food items were consumed more than others among the same food groups, and consumption of many food items varied by gender and age. Specific foods considered high-risk for the transmission of certain enteric pathogens were significantly more likely to be consumed by males (i.e. unpasteurized juice, bean sprouts, and undercooked meat) and elderly individuals (i.e. undercooked eggs). The majority of households prepared and consumed most meals at home, allocating an average of 44 minutes to prepare a meal. Conclusion Baseline data on actual food intake is useful to public health professionals and food safety risk assessors for developing communication messages to consumers and in foodborne outbreak investigations.

  1. Impacts of traditional food consumption advisories: Compliance, changes in diet and loss of confidence in traditional foods

    2011-01-01

    Background Food consumption advisories are often posted when industrial activities are expected to affect the quality and availability of traditional foods used by First Nations. We were recently involved in a project and asked to summarize details regarding the impacts of traditional food consumption advisories with respect to compliance, broader changes in diet and loss of confidence in traditional foods by people. Methods Our review was not conducted as a formal systematic comprehensive review; rather, we focused on primary and grey literature presenting academic, health practitioner and First Nations viewpoints on the topic available from literature databases (i.e., PubMed, Web of KnowledgeSM) as well as the internet search engine Google. Some information came from personal communications. Results Our overview suggests that when communicated effectively and clearly, and when community members are involved in the process, consumption advisories can result in a decrease in contaminant load in people. On the other hand, consumption advisories can lead to cultural loss and have been linked to a certain amount of social, psychological, nutritional, economic and lifestyle disruption. In some cases, communities have decided to ignore consumption advisories opting to continue with traditional lifestyles believing that the benefits of doing so outweigh the risk of following advisories. Conclusions We identified that there are both positive and negative aspects to the issuance of traditional food consumption advisories. A number of variables need to be recognized during the development and implementation of advisories in order to ensure a balance between human health, maintenance of cultures and industrial activity.

    Two studies tested a model where perceived stress was the proposed mediator for the relationship between perceived social support and bulimic behaviors, and between perceived social support and unhealthy food consumption among undergraduate students. Study 1 was a longitudinal, online study in which undergraduate students completed the Multidimensional Scale of Perceived Social Support and the Bulimia Test-Revised at the Time 1 assessment, and the Perceived Stress Scale and the Eating Disorder Examination Questionnaire at the Time 2 assessment, approximately four weeks later. Study 2 was an experimental study in which female participants were randomly assigned into a group with or without social support. Stress was induced with a speech task, followed by a bogus taste task paradigm designed to assess unhealthy food consumption. Bootstrap analyses revealed an indirect effect of perceived social support on bulimic behaviors and unhealthy food consumption through perceived stress. Perceived social support was associated with lower perceived stress in both studies. Lower perceived stress was associated with less self-reported bulimic behaviors in Study 1 and greater consumption of unhealthy foods in Study 2. The negative association between perceived stress and calorie consumption in Study 2 was moderated by dietary restraint. Findings suggest that stress perception helps to explain the relationship between perceived social support and bulimic behaviors, and between perceived social support and calorie consumption. Stress perception may be an important treatment target for eating disorder symptoms among undergraduate students. PMID:27085167

    Limited data exist regarding nutrient intakes and overall dietary quality in Canadian Arctic populations. This cross-sectional study determined the frequency of consumption of traditional meats (e.g. caribou, polar bear, seal, char and whale) and non-traditional store-bought foods including non-traditional meats (e.g. beef, pork and chicken), grains, dairy, fruits, vegetables and non-nutrient dense foods (NNDFs) (e.g. butter, chocolate, chips, candy and pop) by Inuvialuit adults (175 women, mean age 44 ± 14 years; 55 men, mean age 41 ± 13 years) in three remote communities in the Northwest Territories. Using a validated quantitative food frequency questionnaire, frequency of consumption over a 30-day period was determined for 141 commonly reported foods. Mean consumption of traditional meats (1.6 times/day), fruits (1 time/day) and vegetables (0.6 times/day) was less frequent than that of NNDFs (5.0 times/day). Nutritional intervention strategies are needed to promote more frequent consumption of nutrient-rich foods and less frequent consumption of NNDFs in these Arctic communities. PMID:22475024

    The aim of this study was to assess food consumption in Brazilian children 6 to 59 months of age by region of the country and area of residence. This was a descriptive cross-sectional study of 4,322 children in the National Demographic and Health Survey (2006-2007). The data showed low daily consumption of leafy vegetables (12.7%), vegetables (21.8%), and meat (24.6%) and high consumption (1-3 times a week) of soft drinks (40.5%), fried foods (39.4%), salty snacks (39.4%), and sweets (37.8%). Comparing the regions of Brazil, children in the South, Southeast, and Central-West consumed more rice, bread, potatoes, beans, greens, vegetables, and meat, but they also ate more foods not recommended for their age, like sweets and soft drinks (soda). Rural children showed lower consumption of foods recommended for their age and also those not recommended for their age, as compared to their urban counterparts. According to this study, food consumption in these young children fails to meet the recommendations for healthy eating in this age bracket. PMID:23033190

    Strategies for reducing food waste and developing sustainable diets require information about the impacts of consumption behavior and waste generation on climatic, water, and land resources. We quantified the carbon, water, and ecological footprints of 17,110 family members of Chinese households, covering 1935 types of foods, by combining survey data with available life-cycle assessment data sets. We also summarized the patterns of both food consumption and waste generation and analyzed the factors influencing the observed trends. The average person wasted (consumed) 16 (415) kg of food at home annually, equivalent to 40 (1080) kg CO2e, 18 (673) m(3), and 173 (4956) gm(2) for the carbon, water and ecological footprints, respectively. The generation of food waste was highly correlated with consumption for various food groups. For example, vegetables, rice, and wheat were consumed the most and accounted for the most waste. In addition to the three plant-derived food groups, pork and aquatic products also contributed greatly to embedded footprints. The data obtained in this study could be used for assessing national food security or the carrying capacity of resources. PMID:26011615

    Despite the progressive development of the organic food sector in Taiwan, little is known about how consumers' consumption motives will influence organic food decision through various degrees of involvement and whether or not consumers with various degrees of uncertainty will vary in their intention to buy organic foods. The current study aims to examine the effect of consumption motives on behavioral intention related to organic food consumption under the mediating role of involvement as well as the moderating role of uncertainty. Research data were collected from organic food consumers in Taiwan via a questionnaire survey, eventually obtaining 457 valid questionnaires for analysis. This study tested the overall model fit and hypotheses through structural equation modeling method (SEM). The results show that consumer involvement significantly mediates the effects of health consciousness and ecological motives on organic food purchase intention, but not applied to food safety concern. Moreover, the moderating effect of uncertainty is statistical significance, indicating that the relationship between involvement and purchase intention becomes weaker in the condition of consumers with higher degree of uncertainty. Several implications and suggestions are also discussed for organic food providers and marketers. PMID:27178878

    Objective: The aim of the present study was to determine the prevalence of excess weight and analyze eating habits in relation to cardiovascular disease in adolescents from the city of Vitória de Santo Antão, state of Pernambuco, northeast Brazil. Methods: A cross-sectional study was carried out with male and female students (10-19 years old) enrolled at public and private schools in Vitória de Santo Antão. Sociodemographic, anthropometric and lifestyle variables were collected. Food consumption was evaluated using a Food Frequency Questionnaire and subsequently converted to monthly intake pattern scores, obtaining the intake distribution for a group of foods associated with the risk of developing cardiovascular disease and for a group of protective foods. The significance level for the statistical tests was set at 5.0%. Results: The sample consisted of 2866 students. The female gender accounted for 54.2% of the sample, and median age was 14 years (interquartile range: 12-16 years). The food intake scores showed greater dispersion in the group of protective foods (51.1%). Higher median scores for consumption of risk foods were found among adolescents whose mothers had more than 9 years of schooling (p<0.001). Conclusions: Excess weight was prevalent among the students analyzed. The consumption of risk foods was only associated with maternal schooling, which shows the need for nutritional interventions directed at families, regardless of socioeconomic status. PMID:26113308

    Fast food restaurants spend millions of dollars annually on child-targeted marketing, a substantial portion of which is allocated to toy premiums for kids' meals. The objectives of this study were to describe fast food toy premiums, and examine whether young children's knowledge of fast food toy premiums was associated with their fast food consumption. Parents of 3- to 5-year old children were recruited from pediatric and WIC clinics in Southern New Hampshire, and completed a cross-sectional survey between April 2013-March 2014. Parents reported whether their children usually knew what toys were being offered at fast food restaurants, and whether children had eaten at any of four restaurants that offer toy premiums with kids' meals (McDonald's, Burger King, Subway, Wendy's) during the 7 days preceding the survey. Seventy-one percent of eligible parents participated (N = 583); 48.4% did not receive any education beyond high school, and 27.1% of children were non-white. Half (49.7%) the children had eaten at one or more of the four fast food restaurants in the past week; one-third (33.9%) had eaten at McDonald's. The four restaurants released 49 unique toy premiums during the survey period; McDonald's released half of these. Even after controlling for parent fast food consumption and sociodemographics, children were 1.38 (95% CI = 1.04, 1.82) times more likely to have consumed McDonald's if they usually knew what toys were offered by fast food restaurants. We did not detect a relationship between children's toy knowledge and their intake of fast food from the other restaurants. In this community-based sample, young children's knowledge of fast food toys was associated with a greater frequency of eating at McDonald's, providing evidence in support of regulating child-directed marketing of unhealthy foods using toys.

    The present study investigated the influence of a weight loss reality TV show on body satisfaction, mood and food consumption. Young Australian women (N = 99) first completed baseline measures of state body satisfaction and mood. They were then randomly allocated to either a weight loss or a home renovation programme and were provided with snack foods during viewing. Post-measures included state body satisfaction, state mood and trait dietary restraint and snack food consumption. BMI moderated the relationship between condition and body satisfaction and mood. Larger women experienced less body satisfaction and less positive mood in response to the weight loss programme. Dietary restraint moderated the relationship between condition and food consumption. A greater percentage of women with lower dietary restraint ate in the control condition; whilst a greater percentage of women with higher dietary restraint ate food whilst watching the weight loss programme. These findings highlight the potential negative impact of weight-focused reality TV on mood, body satisfaction and snack food consumption among some women. PMID:25936290

    This paper describes the methods used to reconstruct the movement of commercial foods in and through the study area of the Hanford Environmental Dose Reconstruction Project. The most dose-relevant radionuclide released from Hanford separations plants was {sup 131}I via the atmospheric pathway. As a result of atmospheric deposition of {sup 131}I, commercial food supplies may have been contaminated. Because of the half-life of {sup 131}I is relatively short, foods consumed soon after production, such as milk and produce, presented the highest risk. For that reason, this paper deals primarily with the reconstruction of milk and produce production, marketing, and consumption from 1945-1951, the period with the highest known {sup 131}I releases. The reconstructed food production and consumption information was used as input to radiation dose estimates for representative individuals and as default values for real individuals who may not remember where they obtained food or how much they consumed during that period. Specific methods for tracing the movement of commercial milk and produce back from the point of human consumption, through commercial markets, to original production are presented. Results include the characteristics of food consumption exhibited by representative individuals, examples of commercial milk and produce market structures, and a review of commercial milk production and processing practices from 1945-1951.

    Foods advertised were recorded in 2 television (TV) channels. The present article studies the association between products advertised and those consumed by mothers and children. A total of 365 mothers and their children were assessed. A positive correlation was observed between the food advertisements that the mothers recalled and the frequency of TV food advertisements (Rho = 0.44, P = 0.03). A positive correlation was found between the frequency of the foods advertised on TV and the consumption of these by the mothers (r = 0.73, P = 0.0001) and their children (Rho = 0.66, P = 0.0001). These results suggest that TV advertisements influence the food choices of mothers and children. PMID:22695042

    There is mounting evidence that many highly processed foods have addictive properties, and that some cases of compulsive overeating resemble an addiction disorder. While support for the Yale Food Addiction Scale (YFAS) as a valid diagnostic tool has been impressive and continues to increase, to date, no research has examined the food-addiction construct in response to an actual food stimulus, and in relation to direct measures of appetite and food consumption. As part of a larger community-based study of overeating in healthy adults who were predominately overweight and obese (aged 25–50 years), 136 participants completed the YFAS, of whom 23 met the diagnostic criteria for food-addiction. They took part in a 2-day, double-blind, cross-over, single-dose drug challenge using a psychomotor stimulant (methylphenidate) and placebo. Participants were first assessed on ratings of appetite and food cravings after holding and tasting their favorite snack food, after which they were able to eat all or part of the snack, as they wished. Three separate repeated-measures analysis-of-variance procedures were carried out, each with two between-subjects factors (Diagnosis: food-addiction vs. non-food addiction) and (Sex: male vs. female) and 1 within-subjects factor (Days: drug vs. placebo). As anticipated, for all three dependent variables, there was a significant main effect for Days with a response decrease from placebo to the drug condition. With respect to food cravings and appetite ratings, results indicated that the food addiction group had significantly higher scores on both variables. For food consumption, there was a significant Days × Diagnosis interaction whereby the food-addiction group showed no food-intake suppression across days compared to the non-food-addiction group who demonstrated a significant decrease in snack-food consumption with methylphenidate. The finding that the food-addiction group was resistant to the food-intake suppression typically induced by

    The aim of the present study is to explore the contribution of different types of meal intake behaviour on a healthy diet and seeks to find associations with food consumption habits. A cross-sectional survey with data from 1332 Spanish adults aged between 20 and 79 years was conducted. The survey was carried out during the cardiovascular health event 'Semanas del Corazon 2008' in four Spanish cities. Several food consumption habits such as the recommended intake of fruits, vegetables, milk and dairy products, as well as the regular consumption of fatty and salty food and ready-made meals, were used as dependent variables in logistic regression. We evaluated different meal intake behaviour such as the type of meals, snacking, and drinks taken with a meal. Our survey revealed that snacking is positively associated with the regular consumption of salty and fatty food, and having sugary drinks with meals was positively associated with the regular consumption of ready-made meals. Having a forenoon meal is positively associated with the consumption of two or more portions of milk and dairy products and vegetables, and taking an afternoon meal with the recommended intake of milk and dairy products and fruits. Drinking water during a meal increases the probability of consuming two or more portions of fruits and vegetables. Our results enhance the understanding of the contribution that meal intake behaviour makes to a healthy diet based on food consumption habits. This work provides an insight into eating behaviour and would make a useful contribution to interventions aimed at promoting healthier eating habits. PMID:25127937

    Abstract Background: No national studies have examined associations between (1) school food availability and accessibility and (2) secondary student fruit and vegetable (FV) consumption. This article uses 5 years of nationally representative data from secondary school students to examine associations between the school food environment and student fruit and green vegetable consumption. Methods: From 2008 to 2012, cross-sectional, nationally representative data from US middle and high school students were collected annually on self-reported fruit and green vegetable consumption. Each year, data from administrators at each relevant school were collected on food item availability (any venue) and accessibility (total number of school sources). Data were obtained from 10,254 eighth-grade students in 317 schools and 18,898 tenth- and 12th-grade students in 518 schools. Associations were estimated by multi-level models controlling for student- and school-level characteristics. Results: Availability showed minimal association with student consumption. Candy/regular-fat snack accessibility was associated negatively with middle school fruit consumption. Salad bar availability and accessibility were positively associated with middle school green vegetable consumption; FV accessibility was associated positively with high school fruit and green vegetable consumption. Significant associations were consistent across student racial/ethnic and socioeconomic groups. Conclusions: Forthcoming USDA nutrition standards for school foods and beverages sold outside of reimbursable meal programs should result in the removal of school candy/regular-fat snacks. In deciding which items to make available under the new standards, schools should consider increasing the number of FV sources—including salad bars—thereby potentially increasing student FV consumption.

    2013-01-01

    Background Malnutrition in children is a major public health concern. This study aimed to determine the association between dietary diversity and stunting, underweight, wasting, and diarrhea and that between consumption of each specific food group and these nutritional and health outcomes among children. Methods A nationally representative household survey of 6209 children aged 12 to 59 months was conducted in Cambodia. We examined the consumption of food in the 24 hours before the survey and stunting, underweight, wasting, and diarrhea that had occurred in the preceding 2 weeks. A food variety score (ranging from 0 to 9) was calculated to represent dietary diversity. Results Stunting was negatively associated with dietary diversity (adjusted odd ratios [ORadj] 0.95, 95% confident interval [CI] 0.91-0.99, P = 0.01) after adjusting for socioeconomic and geographical factors. Consumption of animal source foods was associated with reduced risk of stunting (ORadj 0.69, 95% CI 0.54-0.89, P < 0.01) and underweight (ORadj 0.74, 95% CI 0.57-0.96, P = 0.03). On the other hand, the higher risk of diarrhea was significantly associated with consumption of milk products (ORadj 1.46, 95% CI 1.10-1.92, P = 0.02) and it was significantly pronounced among children from the poorer households (ORadj 1.85, 95% CI 1.17-2.93, P < 0.01). Conclusions Consumption of a diverse diet was associated with a reduction in stunting. In addition to dietary diversity, animal source food was a protective factor of stunting and underweight. Consumption of milk products was associated with an increase in the risk of diarrhea, particularly among the poorer households. Both dietary diversity and specific food types are important considerations of dietary recommendation. PMID:23866682

    This study examined the relationship among socioeconomic factors, frequency of food away from home (FAFH) and food-consumption patterns of 1,070 housewives, and the association of those factors with obesity, using data from the third Korea National Health and Nutrition Examination Survey. Although lower intakes of fruits, meats, and fast foods were associated with seldom eating out, no consistent pattern was observed regarding the relationship between the frequency of FAFH and food consumption for all groups of housewives. Further analysis indicated that obesity rates were lower among housewives aged 20-49 years with 7-12 years of education and moderate eating-out frequency, compared to older, less educated women. It appeared that reducing the frequency of FAFH does not always entail desirable food intakes among full-time housewives in Korea. Our findings suggest that choosing healthy meals away from home is more important for housewives than refraining from eating out. PMID:21888582

    In California, more than 2 million adolescents (58%) drink soda or other sugar-sweetened beverages every day, and more than 1.6 million adolescents (46%) eat fast food at least twice a week. Adolescents who live and go to school in areas with more fast food restaurants and convenience stores than healthier food outlets such as grocery stores are more likely to consume soda and fast food than teens who live and go to school in areas with healthier food environments. State and local policy efforts to improve the retail food environment may be effective in improving adolescents' dietary behaviors. PMID:21830348

Setting China Kadoorie Biobank in which participants from 10 geographically diverse areas across China were enrolled between 2004 and 2008. Participants 199 293 men and 288 082 women aged 30 to 79 years at baseline after excluding participants with cancer, heart disease, and stroke at baseline. Main exposure measures Consumption frequency of spicy foods, self reported once at baseline. Main outcome measures Total and cause specific mortality. Results During 3 500 004 person years of follow-up between 2004 and 2013 (median 7.2 years), a total of 11 820 men and 8404 women died. Absolute mortality rates according to spicy food consumption categories were 6.1, 4.4, 4.3, and 5.8 deaths per 1000 person years for participants who ate spicy foods less than once a week, 1 or 2, 3 to 5, and 6 or 7 days a week, respectively. Spicy food consumption showed highly consistent inverse associations with total mortality among both men and women after adjustment for other known or potential risk factors. In the whole cohort, compared with those who ate spicy foods less than once a week, the adjusted hazard ratios for death were 0.90 (95% confidence interval 0.84 to 0.96), 0.86 (0.80 to 0.92), and 0.86 (0.82 to 0.90) for those who ate spicy food 1 or 2, 3 to 5, and 6 or 7 days a week, respectively. Compared with those who ate spicy foods less than once a week, those who consumed spicy foods 6 or 7 days a week showed a 14% relative risk reduction in total mortality. The inverse association between spicy food consumption and total mortality was stronger in those who did not consume alcohol than those who did (P=0.033 for interaction). Inverse associations were also observed for deaths due to cancer, ischemic heart diseases, and respiratory diseases. Conclusion In this large prospective study, the habitual

    Background Obesity is a growing global issue that is linked to cognitive and psychological deficits. Objective This preliminary study investigated the efficacy of training to improve inhibitory control (IC), a process linked to overeating, on consumption and cognitive control factors. Methods This study utilized a multisession mobile phone–based intervention to train IC in an overweight and obese population using a randomized waitlist-control design. A combination of self-assessment questionnaires and psychophysiological measures was used to assess the efficacy of the intervention in terms of improved general IC and modified food consumption after training. Attitudes toward food were also assessed to determine their mediating role in food choices. A total of 58 participants (47 female) completed 2 assessment sessions 3 weeks apart, with 2 weeks of intervention training for the training group during this time. The groups did not differ in baseline demographics including age, body mass index, and inhibitory control. Results Inhibitory control ability improved across the training sessions, with increases in P3 amplitude implying increased cognitive control over responses. Inhibitory control training was associated with increased healthy and reduced unhealthy food consumption in a taste test and in the week following training, as measured by the Healthy Eating Quiz and the food consumption test. Cognitive restraint was enhanced after training for the training but not the waitlist condition in the Three-Factor Eating Questionnaire, implying that attempts to avoid unhealthy foods in the future will be easier for the training group participants. Conclusions Inhibitory control training delivered via a purpose-designed mobile phone app is easy to complete, is convenient, and can increase cognitive restraint and reduce unhealthy food consumption.

    Objective To examine whether psychosocial factors mediate (explain) the association between socioeconomic position and takeaway food consumption. Design A cross-sectional postal survey conducted in 2009. Setting Participants reported their usual consumption of 22 takeaway food items, and these were grouped into a “healthy” and “less healthy” index based on each items' nutritional properties. Principal Components Analysis was used to derive three psychosocial scales that measured beliefs about the relationship between diet and health (α = 0.73), and perceptions about the value (α = 0.79) and pleasure (α = 0.61) of takeaway food. A nutrition knowledge index was also used. Socioeconomic position was measured by highest attained education level. Subjects Randomly selected adults (n = 1,500) aged between 25–64 years in Brisbane, Australia (response rate  =  63.7%, N = 903). Results Compared with those with a bachelor degree or higher, participants with a diploma level of education were more likely to consume “healthy” takeaway food (p = 0.023) whereas the least educated (high school only) were more likely to consume “less healthy” choices (p = 0.002). The least educated were less likely to believe in a relationship between diet and health (p<0.001), and more likely to have lower nutritional knowledge compared with their highly educated counterparts (p<0.001). Education differences in beliefs about the relationship between diet and health partly and significantly mediated the association between education and “healthy” takeaway food consumption. Diet- and health-related beliefs and nutritional knowledge partly and significantly mediated the education differences in “less healthy” takeaway food consumption. Conclusions Interventions that target beliefs about the relationship between diet and health, and nutritional knowledge may reduce socioeconomic differences in takeaway food consumption, particularly for

    Recent years have seen considerable interest in examining the impact of food prices on food consumption and subsequent health consequences. Fiscal policies targeting the relative price of unhealthy foods are frequently put forward as ways to address the obesity epidemic. Conversely, various food subsidy interventions are used in attempts to reduce levels of under-nutrition. Information on price elasticities is essential for understanding how such changes in food prices affect food consumption. It is crucial to know not only own-price elasticities but also cross-price elasticities, as food substitution patterns may have significant implications for policy recommendations. While own-price elasticities are common in analyses of the impact of food price changes on health, cross-price effects, even though generally acknowledged, are much less frequently included in analyses, especially in the public health literature. This article systematically reviews the global evidence on cross-price elasticities and provides combined estimates for seven food groups in low-income, middle-income and high-income countries alongside previously estimated own-price elasticities. Changes in food prices had the largest own-price effects in low-income countries. Cross-price effects were more varied and depending on country income level were found to be reinforcing, undermining or alleviating own-price effects. PMID:25236930

    Cessation of drug use often coincides with increased food consumption and weight gain in recovering addicts. However, it is not known whether this phenomenon (particularly the weight gain) is uniquely human, or whether it represents a consequence of drug cessation common across species. To address this issue, rats (n = 10/group) were given systemic injections of D-amphetamine (3 mg/kg) or an equal volume of saline vehicle for 9 consecutive days. Beginning 2 days after the final injection, rats were given free access to a highly palatable food mixture (consisting of sugar and butter) along with their standard chow diet, and food consumption and body weight were measured every 48 h for 30 days. Consistent with clinical observations, amphetamine-treated rats showed a greater increase in body weight over the course of the 30 days relative to vehicle-treated rats. Surprisingly, there was no difference in highly palatable food consumption between amphetamine- and vehicle-treated groups, but the amphetamine-treated group consumed significantly more standard chow than the control group. The finding that a history of chronic amphetamine exposure increases food consumption is consistent with previous work in humans showing that withdrawal from drugs of abuse is associated with overeating and weight gain. The current findings may reflect amphetamine-induced sensitization of mechanisms involved in reward motivation, suggesting that weight gain following drug cessation in humans could be due to similar mechanisms.

    Quantitation of food consumption is necessary when determining mutation responses to multiple chemical exposures in the sex-linked recessive lethal assay in Drosophila. One method proposed for quantitating food consumption by Drosophila is to measure the incorporation of 14C-leucine into the flies during the feeding period. Three sources of variation in the technique of Thompson and Reeder have been identified and characterized. First, the amount of food consumed by individual flies differed by almost 30% in a 24 hr feeding period. Second, the variability from vial to vial (each containing multiple flies) was around 15%. Finally, the amount of food consumed in identical feeding experiments performed over the course of 1 year varied nearly 2-fold. The use of chemical consumption values in place of exposure levels provided a better means of expressing the combined mutagenic response. In addition, the kinetics of food consumption over a 3 day feeding period for exposures to cyclophosphamide which produce lethality were compared to non-lethal exposures. Extensive characterization of lethality induced by exposures to cyclophosphamide demonstrate that the lethality is most likely due to starvation, not chemical toxicity.

    Background: The consumption of different types of fast food is increasingly growing in all parts of the world, both in developed and developing countries. Because of the changes and transitions in the lifestyle and dietary habits of people, an increasing number of people from different age groups, particularly adolescents and young adults, are inclined toward consuming fast food. Objectives: The objective of this study was to investigate the factors influencing fast-food consumption among adolescents in Tehran, Iran. Patients and Methods: The present qualitative study was conducted in 2012 - 2013 in Tehran, the capital of Iran. To achieve the objective of this study, 42 adolescents were enrolled in this study through a purposive sampling method, and the required data was collected via individual semi-structured in-depth interviews. Data collection and analysis were carried out simultaneously, and the collected data was analyzed via a thematic content analysis and using MAXQDA 10 software. Results: In this study after coding the transcribed interviews, the findings were categorized into three main themes as follows: personal views, social factors, and family factors. Each theme included several categories and subcategories, and the coded sentences and phrases were placed under each category and subcategory. Conclusions: The results of this study showed that the number of factors promoting fast-food consumption appeared to be more than the inhibiting factors and that the diverse factors at the individual and social level influenced fast-food consumption among adolescents.

    This study reports the food consumption patterns of adults aged 18 to 59 years in the Malaysian Adults Nutrition Survey (MANS) carried out between October 2002 and December 2003. A total of 6,742 subjects comprising 3,274 men and 3,468 women representing the northern, central , southern and east coast of Peninsular Malaysia as well as Sabah and Sarawak were interviewed. A semiquantitative food frequency questionnaire (FFQ) which consisted of 126 food items was used to evaluate the food consumption pattern (habitual food intake) of the respondents during the previous one- year period. The results demonstrate that nasi putih (cooked rice) was consumed by 97% of the population twice daily (average 2½ plates per day). Other food items consumed daily were marine fish, (one medium fish per day), green leafy vegetables (one cup per day) and sweetened condensed milk (three teaspoons per day. The mean frequencies for daily intake of rice, leafy vegetables, marine fish, local kuih, anchovy (ikan bilis) and biscuits were significantly higher among the rural compared to the urban adults. In contrast, more urban dwellers consumed chicken and eggs more frequently than their rural counterparts. More men than women consumed chicken and eggs more frequently. Malaysian adults showed a satisfactory habit of drinking plain water, with 99% drinking at least six glasses of plain water daily. Other beverages such as tea (47%), coffee (28%), chocolate-based drinks (23%) and cordial syrup (11%) were also consumed on daily basis, however, in a smaller proportion of the population. There were differences in the prevalence of daily consumption of foods when comparing urban and rural population, and also between men and women. The prevalence of daily consumption of marine fish among rural and urban adults was 51% and 34% respectively. For sweetened condensed milk, men and women consumed 43% and 28% respectively; however, more women drank full cream milk than men. Between the age groups, 21

    A recent official report on the Scottish Diet reviews evidence for poor health and poor diets among the Scots, and makes extensive and specific recommendations about dietary change. This paper examines the extent to which reported consumption of fifteen of the food groups discussed in that report vary among four neighbourhoods in Glasgow City. Some foods appear to be typical of a wider Glaswegian (or Scottish) diet and show little variation among neighbourhoods (e.g. semi-skimmed milk, white fish, confectionery, cakes and pastries, savoury snacks). Other foods however show marked differences between neighbourhoods after controlling for sex, age and social class; these include fruit, vegetables, meat (particularly processed meat products), bread, spreading fats, sugar, natural fruit juice and alcohol. This suggests that such intraurban variations in food consumption cannot be explained simply by socio-demographic or socio-economic factors in individuals and that cultural and supply factors also need to be taken into account.

  10. Relative Preference and Localized Food Affect Predator Space Use and Consumption of Incidental Prey.

    Schartel, Tyler E; Schauber, Eric M

    2016-01-01

    Abundant, localized foods can concentrate predators and their foraging efforts, thus altering both the spatial distribution of predation risk and predator preferences for prey that are encountered incidentally. However, few investigations have quantified the spatial scale over which localized foods affect predator foraging behavior and consumption of incidental prey. In spring 2010, we experimentally tested how point-source foods altered how generalist predators (white-footed mice, Peromyscus leucopus) utilized space and depredated two incidental prey items: almonds (Prunus dulcis; highly profitable) and maple seeds (Acer saccharum; less profitable). We estimated mouse population densities with trapping webs, quantified mouse consumption rates of these incidental prey items, and measured local mouse activity with track plates. We predicted that 1) mouse activity would be elevated near full feeders, but depressed at intermediate distances from the feeder, 2) consumption of both incidental prey would be high near feeders providing less-preferred food and, 3) consumption of incidental prey would be contingent on predator preference for prey relative to feeders providing more-preferred food. Mouse densities increased significantly from pre- to post-experiment. Mean mouse activity was unexpectedly greatest in control treatments, particularly <15 m from the control (empty) feeder. Feeders with highly preferred food (sunflower seeds) created localized refuges for incidental prey at intermediate distances (15 to 25m) from the feeder. Feeders with less-preferred food (corn) generated localized high risk for highly preferred almonds <10 m of the feeder. Our findings highlight the contingent but predictable effects of locally abundant food on risk experienced by incidental prey, which can be positive or negative depending on both spatial proximity and relative preference.

    Abundant, localized foods can concentrate predators and their foraging efforts, thus altering both the spatial distribution of predation risk and predator preferences for prey that are encountered incidentally. However, few investigations have quantified the spatial scale over which localized foods affect predator foraging behavior and consumption of incidental prey. In spring 2010, we experimentally tested how point-source foods altered how generalist predators (white-footed mice, Peromyscus leucopus) utilized space and depredated two incidental prey items: almonds (Prunus dulcis; highly profitable) and maple seeds (Acer saccharum; less profitable). We estimated mouse population densities with trapping webs, quantified mouse consumption rates of these incidental prey items, and measured local mouse activity with track plates. We predicted that 1) mouse activity would be elevated near full feeders, but depressed at intermediate distances from the feeder, 2) consumption of both incidental prey would be high near feeders providing less-preferred food and, 3) consumption of incidental prey would be contingent on predator preference for prey relative to feeders providing more-preferred food. Mouse densities increased significantly from pre- to post-experiment. Mean mouse activity was unexpectedly greatest in control treatments, particularly <15 m from the control (empty) feeder. Feeders with highly preferred food (sunflower seeds) created localized refuges for incidental prey at intermediate distances (15 to 25m) from the feeder. Feeders with less-preferred food (corn) generated localized high risk for highly preferred almonds <10 m of the feeder. Our findings highlight the contingent but predictable effects of locally abundant food on risk experienced by incidental prey, which can be positive or negative depending on both spatial proximity and relative preference.

    Background: The proposed changes to the Nutrition Facts Label by the US Food and Drug Administration will include information on added sugars for the first time. Objective: The objective was to evaluate the sources of added sugars in the diets of a representative sample of US children and adults by food purchase location and food source (eg, food group). Design: This cross-sectional study among 31,035 children, adolescents, and adults aged ≥6 y from the 2003–2004, 2005–2006, 2007–2008, and 2009–2010 NHANES used data from a 24-h dietary recall to evaluate consumption of added sugars. Food locations of origin were identified as stores (supermarket or grocery store), quick-service restaurants/pizza (QSRs), full-service restaurants (FSRs), schools, and others (eg, vending machines or gifts). Added sugars consumption by food purchase location was evaluated by age, family income-to-poverty ratio, and race-ethnicity. Food group sources of added sugars were identified by using the National Cancer Institute food categories. Results: Added sugars accounted for ∼14.1% of total dietary energy. Between 65% and 76% of added sugars came from stores, 6% and 12% from QSRs, and 4% and 6% from FSRs, depending on age. Older adults (aged ≥51 y) obtained a significantly greater proportion of added sugars from stores than did younger adults. Lower-income adults obtained a significantly greater proportion of added sugars from stores than did higher-income adults. Intake of added sugars did not vary by family income among children/adolescents. Soda and energy and sports drinks were the largest food group sources of added sugars (34.4%), followed by grain desserts (12.7%), fruit drinks (8.0%), candy (6.7%), and dairy desserts (5.6%). Conclusions: Most added sugars came from foods obtained from stores. The proposed changes to the Nutrition Facts Label should capture the bulk of added sugars in the US food supply, which suggests that the recommended changes have the potential to

    Public health bodies in many countries are attempting to increase population-wide habitual consumption of whole grains. Limited data on dietary habits exist in Singaporean children. The present study therefore aimed to assess whole grain consumption patterns in Singaporean children and compare these with dietary intake, physical activity and health parameters. Dietary intake (assessed by duplicate, multipass, 24-h food recalls), physical activity (by questionnaire) and anthropometric measurements were collected from a cross-section of 561 Singaporean children aged 6-12 years. Intake of whole grains was evaluated using estimates of portion size and international food composition data. Only 38·3 % of participants reported consuming whole grains during the dietary data collection days. Median intake of whole grains in consumers was 15·3 (interquartile range 5·4-34·8) g/d. The most commonly consumed whole-grain food groups were rice (29·5 %), wholemeal bread (28·9 %) and ready-to-eat breakfast cereals (18·8 %). A significantly lower proportion of Malay children (seven out of fifty-eight; P < 0·0001) consumed whole grains than children of other ethnicities. Only 6 % of all children consumed the amount of whole grains most commonly associated with improved health outcomes (48 g/d). There was no relationship between whole grain consumption patterns and BMI, waist circumference or physical activity but higher whole grain intake was associated with increased fruit, vegetable and dairy product consumption (P < 0·001). These findings demonstrate that consumption of whole grain foods is low at a population level and infrequent in Singaporean children. Future drives to increase whole-grain food consumption in this population are likely to require input from multiple stakeholders. PMID:27547396

    A high sugar intake is a subject of scientific debate due to the suggested health implications and recent free sugar recommendations by the WHO. The objective was to complete a food composition table for added and free sugars, to estimate the intake of total sugars, free sugars, and added sugars, adherence to sugar guidelines and overall diet quality in Dutch children and adults. In all, 3817 men and women (7–69 years) from the Dutch National Food Consumption Survey 2007–2010 were studied. Added and free sugar content of products was assigned by food composition tables and using labelling and product information. Diet was assessed with two 24-h recalls. Diet quality was studied in adults with the Dutch Healthy Diet-index. Total sugar intake was 22% Total Energy (%TE), free sugars intake 14 %TE, and added sugar intake 12 %TE. Sugar consumption was higher in children than adults. Main food sources of sugars were sweets and candy, non-alcoholic beverages, dairy, and cake and cookies. Prevalence free sugar intake <10 %TE was 5% in boys and girls (7–18 years), 29% in women, and 33% in men. Overall diet quality was similar comparing adults adherent and non-adherent to the sugar guidelines, although adherent adults had a higher intake of dietary fiber and vegetables. Adherence to the WHO free sugar guidelines of <5 %TE and <10 %TE was generally low in the Netherlands, particularly in children. Adherence to the added and free sugar guidelines was not strongly associated with higher diet quality in adults. PMID:26828518

    The aim of the study was to explore the association between perceived stress, depression and food consumption frequency. A self-administered questionnaire that included the perceived stress scale, the depression scale and dietary intake was used in the baseline survey of a cohort study of 2579 local college students over 7 cities in China. Gender and city differences were found in perceived stress scores and depression scores. There were also significant differences among diverse smoking levels and among perceived weight categories in perceived stress and depression scores. Stepwise logistic regression models found that frequency of consumption of fresh fruit, ready-to-eat food and snack food had apparently independent effects on perceived stress, whereas the intake level of fresh fruit, ready-to-eat food and fast food was significantly associated with depression. The link between food consumption frequency, perceived stress and depression suggests that diet intervention may be considered a mediate strategy integrated in psychology prevention program among normal population of the college.

    In many parts of the world, freshwater is already a scarce and overexploited natural resource, raising concerns about global food security and damage to freshwater ecosystems. This situation is expected to intensify with the FAO estimating that world food production must double by 2050. Food chains must therefore become much more efficient in terms of consumptive water use. For the small and geographically well-defined Australian mango industry, having an average annual production of 44 692 t of marketable fresh fruit, the average virtual water content (sum of green, blue and gray water) at orchard gate was 2298 l kg-1. However, due to wastage in the distribution and consumption stages of the product life cycle, the average virtual water content of one kg of Australian-grown fresh mango consumed by an Australian household was 5218 l. This latter figure compares to an Australian-equivalent water footprint of 217 l kg-1, which is the volume of direct water use by an Australian household having an equivalent potential to contribute to water scarcity. Nationally, distribution and consumption waste in the food chain of Australian-grown fresh mango to Australian households represented an annual waste of 26.7 Gl of green water and 16.6 Gl of blue water. These findings suggest that interventions to reduce food chain waste will likely have as great or even greater impact on freshwater resource availability as other water use efficiency measures in agriculture and food production.

    Food consumption, digesta retention time, and food preference were measured for captive whooping cranes fed pelleted diets. The basal commercial diet was compared to four mixtures containing 70% basal and 30% of one of four important winter foods for the whooping crane: blue crab (Callinectes sapidus), wolfberry fruit (Lycium carolinianurn), live oak acorn (Quercus virginiana), or common Rangia clam (Rangia cuneata). Because captive birds would not eat whole foods, we were prevented from direct food preference tests. Food passed through the gut rapidly, with almost complete elimination within 7 hr. There was some indication that retention time was shorter for the low fiber and high ash and calcium clam diet. Cranes ate less wolfberry feed (g/day) than the other feeds, and all birds ate less wolfberry feed on the day it was first fed, compared to basal diet the previous day. Birds ate more low energy feed than high energy feed. Due to combined effects of low energy content, lower metabolizable energy coefficients, and reduced feed consumption, less energy was assimilated for study diets than basal diet. Apparent shorter retention times for some diets con-taming whooping crane foods may partly explain lower digestibilities and metabolizable energy of winter whooping crane foods compared to commercial crane diet.

    Abstract Foodborne pathogens are a leading cause of mild-to-severe gastrointestinal illnesses worldwide. Escherichia coli pathotypes have been known to cause gastrointestinal illnesses in children less than 5 years old in Colombia. However, insufficient information is available on the prevalence of E. coli contamination of food products and the kind of E. coli food product reservoirs. The two objectives of this study were designed to address this issue. The first objective was to ascertain coliform, E. coli, and pathogenic E. coli contamination of food products readily available for human consumption in Cartagena, Colombia. The second objective was to evaluate the relationship between pathogenic E. coli isolated from food products and those isolated from cases of diarrhea in children. Food product samples consisting of pasteurized milk, unpasteurized fruit juice, ground beef, cheese, and vegetables were obtained at four retail stores. The food samples were cultured in liquid media and tested for the presence of coliforms and E. coli. E. coli isolates were tested by polymerase chain reaction for the presence of pathogenic E. coli. Coliforms, E. coli, and E. coli intestinal pathotypes contamination were detected in 88.4%, 53%, and 2.1% of food product samples, respectively. Ground beef and cheese were the only food samples contaminated with E. coli intestinal pathotypes including enteropathogenic (EPEC), Shiga toxin–producing (STEC), and enterotoxigenic E. coli (ETEC). Closed multilocus sequencing typing relationships between diarrheagenic E. coli isolates from food products and from individuals with diarrhea suggest that food products readily available at public markets in Cartagena can transmit ETEC and possibly EPEC and STEC. We demonstrated that a high proportion of food products for human consumption available at public markets in Cartagena are contaminated with coliforms, E. coli, and E. coli intestinal pathogens. Furthermore, food products containing E. coli

    Increased intake of saturated fat and refined sugars underlies much of the problem of emerging obesity all over the world. This includes middle-income countries like Thailand, which are subject to successful marketing of Western fast foods especially targeted at adolescents. In this study we explore the socio-cultural influences on fast-food intake for non-metropolitan (rural and urban) adolescents in North East Thailand (Isan). Our questionnaire sample included 634 persons aged 15-19 years who are in and out of formal schooling and who are randomly representing upper, central and lower Isan. All were asked about their knowledge of fast-food health risks and their attitudes towards, and consumption of, fast food and traditional food. As well, we used several focus groups to obtain qualitative data to complement the information derived from the questionnaire. Some three quarters of sampled youth were aware that fast food causes obesity and half knew of the link to heart disease. About half consumed fast food regularly, induced by the appeal of 'modern' lifestyles, social events and marketing, as well as by the convenience, speed and taste. Nearly two-thirds thought that local foods should be more popular and these beliefs were more likely to be found among children from educated and urban families. Local foods already constitute a cultural resistance to fast-food uptake. We propose several methods to boost this resistance and protect the youth of Thailand against fast food and its many adverse health consequences. PMID:21547247

    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. PMID:25363129

    Limited data are available on the residue levels of polybrominated diphenyl ethers (PBDEs) in baby food. In this study, 24 PBDE congeners were determined in 147 homemade baby food samples collected from 97 households for 6-, 9-, 12-, 15-, and from 24 to 27-month-old infant groups during the period of 2012-2013. The concentrations of total PBDEs (ΣPBDE) ranged from 24.5 to 6000 (mean: 263) pg/g fresh weight, higher than those found in commercial formulae from the United States. The predominant congeners were BDEs 209 and 47, accounting for 92% of the ΣPBDE concentrations, reflected by high deca-BDE consumption in Korea. The residue levels and detection rates of BDE 47 in the baby food samples showed a gradual increasing trend with an increase in infant ages, due to changes in the food ingredients from hypoallergenic to greasy. The daily intakes of BDEs 47 and 209 via baby food consumption ranged from 0.04 to 0.58, 0.80 to 20.3, and 1.06 to 22.3 ng/kg body weight/day for 6-, 9-, 12-, 15-, and 24-27-month-old infant groups, respectively; these intakes were lower than the oral reference doses proposed by the US EPA. Together with three exposure sources, baby food, breast milk and dust ingestion for 6-month-old infants, the daily intake of ΣPBDE was 25.5 ng/kg body weight/day, which was similar to the intake via baby food consumption only for over 24-month-old infants in our study. This indicates that baby food is an important exposure pathway of PBDEs for over 24-month-old infants. This is the first study regarding the occurrence and exposure assessment of PBDEs via homemade baby food. PMID:25218705

    While thinking about food is a ubiquitous facet of daily life, the perils of imaginary eating are well documented; food-related mental imagery elevates both cravings and consumption. Given the serious health issues that often arise from overeating and obesity, identifying strategies that can be used to combat the link between imagination and consumption is, therefore, of considerable theoretical and practical importance. Here we explored the possibility that a fundamental property of mental imagery-the visual perspective from which an event is viewed-may alter the appraisal of unhealthy foods. Specifically, because it is accompanied by attenuated sensorimotor activity, third-person (cf. first-person) imagery was expected to weaken the link between imagination and consumption. The results of 3 studies supported this prediction showing that third-person (cf. first-person) simulations decreased the mental representation, actual consumption, and willingness to pay for desirable items. Driving these effects was the natural reduction of sensory components furnished by third-person imagery. Together, these findings suggest that adoption of a third-person vantage point during mental imagery may be a viable and effective tactic for curbing consumption in everyday life. PMID:26844366

    This paper presents evidence on the impact of individual as well as regional characteristics on the dynamics of fat, protein, alcohol and cigarette consumption, and on the diversity of the diet in Russia between 1994 and 2005. All those aspects of nutritional behavior are important inputs to the production of health. A dynamic panel data model is used to estimate demand functions for fat, protein, alcohol, cigarettes and diversity of the diet. The results suggest the existence of strong habits in drinking and smoking, and the absence of habits in fat and protein consumption. We also found evidence of habit formation for food diversity. Comparing nutritional behavior of younger and older consumers, we find significant differences in the demand for fat and cigarettes. Older consumers seem to be more persistent in their drinking and smoking behavior. Similarly, men show higher habit persistence for alcohol and cigarette consumption. The results also suggest that among individual determinants, especially education, income and employment have statistically significant impacts on consumption behavior. Regarding the macroeconomic variables, economic growth is negatively related to protein consumption, while regional unemployment rate is negatively affecting the demand for protein and food diversity. Finally, Russian consumers react to the price changes of alcohol, cigarettes, fat and protein as suggested by theory. Consumer demand for food diversity responds negatively to price changes of alcohol and cigarettes, but positively to the price of fat. PMID:23562250

    Background: Poor nutrition habits in adolescent girls endanger their health and are followed by serious systemic diseases in adulthood and negative effects on their reproductive health. To design health promotion programs, understanding of the intra- and interpersonal associated factors with treatment is essential, and this was the aim of this study. Materials and Methods: This cross-sectional study was conducted on 193 adolescent girls of age 11-15 years. Random cluster selection was used for sample selection. Food group consumption pattern was assessed by food frequency questionnaire. Also, perceived susceptibility/severity and nutritional attitude as intrapersonal factors and social support as interpersonal factor were assessed. The relationship between food group consumption level and nutritional attitude and perceived treat (susceptibility/severity) as intrapersonal factors and perceived social support as interpersonal factor were assessed by linear multiple regression and analysis of variance (ANOVA). Results: Results showed that the level of sweetmeat food consumption was related to perceived social support (P = 0.03) and nutritional attitude (P = 0.01) negatively. In addition, an inverse and significant association was found between the level of junk food intake and informational perceived social support (P = 0.004). The association between the level of fast food intake and the perceived parental social support for preparation of healthy food was negatively significant (P = 0.03). Breakfast consumption was related to nutritional attitude (P = 0.03), social support (P = 0.03), and perceived severity (P = 0.045). Conclusions: Results revealed that perceived social support and nutritional attitude are the important and related factors in dietary intake among girls, and promotion of social support and modification of nutritional attitude may lead to healthy nutritional behaviors among them.

    Objective: Skipping breakfast and consuming fast food are related to the risk of obesity and are common adolescent behaviors. The relationship between these behaviors and biomarkers related to diabetes and CVD is understudied in this population. Methods: Data are from a study of the etiologic factors related to obesity risk in adolescents. Breakfast and fast food consumption were assessed using a self-report survey. Anthropometrics, fasting lipids, glucose, insulin, and homeostatic model assessment for insulin resistance (HOMA-IR) were assessed. Multivariate analyses were used to examine the relationship between dietary behaviors and selected biomarkers, controlling for calories consumed, body mass index (BMI), and demographic covariates. Results: 367 adolescents (11 to 18-years; mean 14.7 ± 1.8 years) were assessed at the University of Minnesota-Twin Cities from 2006–2008. Breakfast consumption was significantly associated with lower BMI, body fat, insulin, HOMA-IR, and metabolic syndrome (MetS) cluster score, while fast food consumption was associated with higher BMI, body fat, low-density lipoprotein cholesterol, triglycerides, glucose, insulin, HOMA-IR, and MetS cluster score. Some gender differences were observed. Conclusion: Breakfast and fast food consumption appear to be related to important metabolic syndrome biomarkers for chronic disease in a sample of healthy adolescents. The importance of this finding needs to be validated by examining the stability of this pattern over time and to assess the pattern in other populations. PMID:26844187

    The key stocks and flows of phosphorus (P) through food consumption in Beijing and Tianjin, two megacities in northern China, were explored using a material flow analysis (MFA) approach to construct a static model of P metabolism. A total of 4498 t P has accumulated with 72% of P flow imported through food consumption eventually remaining in Beijing in 2008. Around 64% of the total inflow of P (2670 t) remained in Tianjin in 2008. P in the uncollected sewage from both urban and rural residents and the effluents from sewage treatment plants has significant negative effects on water quality. An average of 55% the P flow remained in the sewage sludge through urban food consumption. The key problems in P metabolism and management in megacities are identified based on the quantitative analysis of P cycling through food consumption. Relevant solutions for improving P recycling efficiency are also discussed. It is important to link P flows with environmental regulations and to establish a strong coordination between urban and rural areas for nutrient recycling to attain sustainable development of megacities.

    2011-01-01

    Fast food is popular among children and adolescents; however, its consumption has often been associated with negative impacts on nutrition and health. This study examined current fast food consumption status among middle school students and explored factors influencing fast food consumption by applying Theory of Planned Behavior. A total of 354 (52.5% boys) students were recruited from a middle school. The subjects completed a pre-tested questionnaire. The average monthly frequency of fast food consumption was 4.05 (4.25 for boys, 3.83 for girls). As expected, fast food consumption was considered to be a special event rather than part of an everyday diet, closely associated with meeting friends or celebrating, most likely with friends, special days. The Theory of Planned Behavior effectively explained fast food consumption behaviors with relatively high R2 around 0.6. Multiple regression analyses showed that fast food consumption behavior was significantly related to behavioral intention (b = 0.61, P < 0.001) and perceived behavioral control (b = 0.19, P < 0.001). Further analysis showed that behavioral intention was significantly related to subjective norm (b = 0.15, P < 0.01) and perceived behavioral control (b = 0.56, P < 0.001). Attitude toward fast food consumption was not significantly associated with behavioral intention. Therefore, effective nutrition education programs on fast food consumption should include components to change the subjective norms of fast food consumption, especially among peers, and perceived behavioral control. Further studies should examine effective ways of changing subjective norms and possible alternatives to fast food consumption for students to alter perceived behavioral control. PMID:21556232

    2014-01-01

    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. PMID:25363129

    Background and Objective. Few data are available linking fast food intake to diet quality in developing countries. This study was conducted to determine the association between fast food consumption and diet quality as well as obesity among Isfahani girls. Methods. This cross-sectional study was done among 140 Iranian adolescents selected by the use of systematic cluster random sampling. Dietary intakes were assessed using a validated food frequency questionnaire. Diet quality was defined based on energy density and nutrient adequacy ratios (NARs). Results. Individuals in the highest quartile of fast food intake had significantly lower NARs for vitamin B1 (P = 0.008), phosphorus (P = 0.0250), selenium (P < 0.001) and vitamin B2 (P = 0.012) compared with those in the lowest quartile. Those in top quartile of fast food intake consumed more energy-dense diets than those in the bottom quartile (P = 0.022). High intakes of fast foods were significantly associated with overweight (top quartile: 40% versus bottom quartile: 0%, P = 0.0001) and obesity (11.4% versus 2.9%, P = 0.0001). Conclusion. Fast food consumption is associated with poor diet quality and high prevalence of overweight and obesity among Isfahani adolescents. Prospective data are required to confirm these findings.

    In the current study, the associations of reward sensitivity with weight related behaviors and body mass index were investigated in a general population sample of 443 Flemish children (50.3% boys) aged 5.5-12 years. Cross-sectional data on palatable food consumption frequency, screen time, physical activity, parental education level and measured length and weight were collected. The Drive subscale of the 'Behavioral Inhibition Scale/Behavioral Activation Scale' was used as a short method to measure reward sensitivity. A significant positive association of reward sensitivity with the fast food and sweet drink consumption frequency was found. Furthermore, a significant positive association of reward sensitivity with the z-score of body mass index was demonstrated, which explained additional variance to the variance explained by palatable food consumption frequency, screen time, physical activity and parental education level. Hence, the assessment of reward sensitivity may have an added value to the assessment of weight-related behavior indicators when evaluating the determinants of overweight in a child. In sum, children high in reward sensitivity might be more attracted to fast food and sweet drinks, and hence, might be more vulnerable to develop unfavorable food habits and overweight. These findings suggest that considering inter-individual differences in reward sensitivity is of importance in future childhood obesity prevention campaigns. PMID:26898320

    This report details the methods used and the results of the study on the estimated historic levels of food consumption by individuals in the Hanford Environmental Dose Reconstruction (HEDR) study area from 1945--1957. This period includes the time of highest releases from Hanford and is the period for which data are being collected in the Hanford Thyroid Disease Study. These estimates provide the food-consumption inputs for the HEDR database of individual diets. This database will be an input file in the Hanford Environmental Dose Reconstruction Integrated Code (HEDRIC) computer model that will be used to calculate the radiation dose. The report focuses on fresh milk, eggs, lettuce, and spinach. These foods were chosen because they have been found to be significant contributors to radiation dose based on the Technical Steering Panel dose decision level.

  3. Toward a quantitative theory of food consumption choices and body weight.

    We propose a calibrated dynamic model of food consumption choices and body weight to study changes in daily caloric intake, weight, and the away-from-home share of calories consumed by adult men and women in the U.S. during the period between 1971 and 2006. Calibration reveals substantial preference heterogeneity between men and women. For example, utility losses stemming from weight gains are ten times greater for women compared to men. Counterfactual experiments show that changes in food prices and household income account for half of the increase in weight of adult men, but only a small fraction of women's weight. We argue that quantitative models of food consumption choices and body weight have a unique role to play in future research in the economics of obesity. PMID:25453360

  5. The influence of oral processing, food perception and social aspects on food consumption: a review.

    PubMed

    Pereira, L J; van der Bilt, A

    2016-08-01

    Eating is an essential activity to get energy and necessary nutrients for living. While chewing, the food is broken down by the teeth and dissolved by saliva. Taste, flavour and texture are perceived during chewing and will contribute to the appreciation of the food. The senses of taste and smell play an important role in selecting nutritive food instead of toxic substances. Also visual information of a food product is essential in the choice and the acceptance of food products, whereas auditory information obtained during the chewing of crispy products will provide information on whether a product is fresh or stale. Food perception does not just depend on one individual sense, but appears to be the result from multisensory integration of unimodal signals. Large differences in oral physiology parameters exist among individuals, which may lead to differences in food perception. Knowledge of the interplay between mastication and sensory experience for groups of individuals is important for the food industry to control quality and acceptability of their products. Environment factors during eating, like TV watching or electronic media use, may also play a role in food perception and the amount of food ingested. Distraction during eating a meal may lead to disregard about satiety and fullness feelings and thus to an increased risk of obesity. Genetic and social/cultural aspects seem to play an important role in taste sensitivity and food preference. Males generally show larger bite size, larger chewing power and a faster chewing rhythm than females. The size of swallowed particles seems to be larger for obese individuals, although there is no evidence until now of an 'obese chewing style'. Elderly people tend to have fewer teeth and consequently a less good masticatory performance, which may lead to lower intakes of raw food and dietary fibre. The influence of impaired mastication on food selection is still controversial, but it is likely that it may at least cause

    Current and potential future trends in technology, consumption and trade of food that may impact on food-borne disease are analysed and the key driving factors identified focusing on the European Union and, to a lesser extent, accounting for the United States and global issues. Understanding of factors is developed using system-based methods and their impact is discussed in relation to current events and predictions of future trends. These factors come from a wide range of spheres relevant to food and include political, economic, social, technological, regulatory and environmental drivers. The degree of certainty in assessing the impact of important driving factors is considered in relation to food-borne disease. The most important factors driving an increase in the burden of food-borne disease in the next few decades were found to be the anticipated doubling of the global demand for food and of the international trade in food next to a significantly increased consumption of certain high-value food commodities such as meat and poultry and fresh produce. A less important factor potentially increasing the food-borne disease burden would be the increased demand for convenience foods. Factors that may contribute to a reduction in the food-borne disease burden were identified as the ability of governments around the world to take effective regulatory measures as well as the development and use of new food safety technologies and detection methods. The most important factor in reducing the burden of food-borne disease was identified as our ability to first detect and investigate a food safety issue and then to develop effective control measures. Given the global scale of impact on food safety that current and potentially future trends have, either by potentially increasing or decreasing the food-borne disease burden, it is concluded that a key role is fulfilled by intergovernmental organisations and by international standard setting bodies in coordinating the

    Individuals suffering from IgE-mediated food allergy usually have to practise life-long food allergen avoidance. This document aims to provide an overview of recent evidence-based recommendations for allergen risk assessment and management in the food industry and discusses unmet needs and expectations of the food allergic consumer in that context. There is a general duty of care on the food industry and obligations in European Union legislation to reduce and manage the presence of allergens alongside other food hazards. Current evidence enables quantification of allergen reference doses used to set-up reliable food safety management plans for some foods. However, further work is required to include a wider variety of foods and to understand the impact of the food matrix as well as additional factors which affect the progression and severity of symptoms as a function of dose. Major concerns have been raised by patients, carers and patient groups about the use of precautionary 'may contain' labelling to address the issue of unintended presence of allergens; these therefore need to be reconsidered. New and improved allergen detection methods should be evaluated for their application in food production. There is an urgent requirement for effective communication between healthcare professionals, patient organizations, food industry representatives and regulators to develop a better approach to protecting consumers with food allergies.

    India is undergoing a shift in consumption from traditional foods to processed foods high in sugar, salt and fat. Partially hydrogenated vegetable oils (PHVOs) high in trans-fat are often used in processed foods in India given their low cost and extended shelf life. The World Health Organization has called for the elimination of PHVOs from the global food supply and recommends their replacement with polyunsaturated fat to maximize health benefits. This study examined barriers to replacing industrially produced trans-fat in the Indian food supply and systematically identified potential policy solutions to assist the government in encouraging its removal and replacement with healthier polyunsaturated fat. A combination of food supply chain analysis and semi-structured interviews with key stakeholders was conducted. The main barriers faced by the food-processing sector in terms of reducing use of trans-fat and replacing it with healthier oils in India were the low availability and high cost of oils high in polyunsaturated fats leading to a reliance on palm oil (high in saturated fat) and the low use of those healthier oils in product reformulation. Improved integration between farmers and processors, investment in technology and pricing strategies to incentivize use of healthier oils for product reformulation were identified as policy options. Food processors have trouble accessing sufficient affordable healthy oils for product reformulation, but existing incentives aimed at supporting food processing could be tweaked to ensure a greater supply of healthy oils with the potential to improve population health.

    1984-10-01

    Three experiments were performed on domestic pigeons deprived of food for 24 hr to determine whether the anorexic influence of naloxone, which is observed in this species, results from a central effect of this drug. Injections were given 15 min before the delivery of food, and repeated measures of the consumption of food were obtained during the next 20 min. The systemic administration of either 2 or 10 mumol of naloxone, but not of equimolar amounts of quaternary naloxone, that does not traverse the blood-brain barrier, reduced the consumption of food of the pigeons. At a dose of 20 mumol, quaternary naloxone also slightly attenuated the ingestion of food, possibly because this drug can penetrate the blood-brain barrier when given in large doses. In another experiment, the intraventricular administration of 12.5, 25, 50, or 100 micrograms of naloxone attenuated the food intake in a dose-related fashion. Injection of 25 micrograms of the antagonist was more efficient in this respect when administered intraventricularly rather than systemically. From these experiments, it is concluded that in pigeons, the anorexic influence of naloxone is, at least partly, centrally mediated. PMID:6521852

    The Great Sensations Program is a nutrition-education project developed for high school students. It was designed to (a) decrease students' consumption of salty snacks and (b) increase students' consumption of fresh fruit snacks. The overall programs were designed following principles of social learning: informative instruction, participatory classroom activities, personal goal setting, feedback, and reinforcement. The program was delivered in six lessons during regular health-education classes. A parental involvement program consisted of mailers and telephone calls to parents to teach them to encourage changes in student snacking habits. A schoolwide program was designed to provide out-of-class peer support for student modifications in salty snack foods. The program was evaluated in one high school using a 2 X 2 design. A second high school served as a no-treatment control. Program assessments were made at both schools before and after the classes, at the end of the school year, and the following fall the next school year following summer vacation. The schoolwide media program was effective in decreasing consumption of salty snack foods and in increasing consumption of target snack foods. However, only those students receiving classroom instruction maintained those changes until the end of the school year. No changes were maintained across summer vacation. These outcomes suggest that school programs developed using principles of social learning may be effective in facilitating important behavior changes at home and at school. PMID:4048086

    The introduced mollusciphagic black carp Mylopharyngodon piceus poses a significant threat to native mollusks in temperate waters throughout the northern hemisphere, but consumption rates necessary to estimate the magnitude of impact on mollusks have not been established. We measured food consumption and growth rates for small (77–245 g) and large (466–1,071 g) triploid black carp held individually under laboratory conditions at 20, 25, and 30°C. Daily consumption rates (g food · g wet weight fish−1·d−1·100) of black carp that received prepared feed increased with temperature (small black carp 1.39–1.71; large black carp 1.28–2.10), but temperature-related increases in specific growth rate (100[ln(final weight) - ln(initial weight)]/number of days) only occurred for the large black carp (small black carp −0.02 to 0.19; large black carp 0.16–0.65). Neither daily consumption rates (5.90–6.28) nor specific growth rates (0.05–0.24) differed among temperatures for small black carp fed live snails. The results of these laboratory feeding trials indicate food consumption rates can vary from 289.9 to 349.5 J·g−1·d−1 for 150 g black carp receiving prepared feed, from 268.8 to 441.0 J·g−1·d−1for 800 g black carp receiving prepared feed, and from 84.8 to 90.2 J·g−1·d−1 for 150 g black carp that feed on snails. Applying estimated daily consumption rates to estimated biomass of native mollusks indicates that a relatively low biomass of bla

    Objective To evaluate the association between the consumption of unhealthy foods in children under one year and the education level of the mothers, data obtained from participants of the II Survey on the prevalence of breastfeeding in the Brazilian capitals and the Federal District in 2008 was analyzed. Methods During the second stage of the campaign for multi-vaccination, a questionnaire on food consumption in the last 24 hours was given to mothers or guardians of children under one year old. We analyzed the consumption of unhealthy foods according to age group, maternal education, region of residence and breastfeeding status. The state capitals and the Federal District were grouped according to the five macro-regions of the country (North, Northeast, Southeast, South and West). Processed juice, soda, coffee, cookies/salted snacks and sugar and/or honey were defined as unhealthy foods. Prevalence ratios (RP) for the association between the consumption of unhealthy foods and maternal education were estimated using Poisson regression models. Results: The study included 34,366 children. The consumption of sweet foods started early and was predominant until the age of six months; after this age, the consumption of biscuits and/or snacks became more prevalent. The consumption of these foods also differs in relation to the macro-region of residence. Consumption of unhealthy foods was higher among mothers with lower education levels. Conclusions The consumption of unhealthy foods by Brazilian children under one year old was high, indicating a need for developing effective strategies to combat the consumption of unhealthy foods in Brazilian children as a way of preventing obesity and other future disorders.

    Over the last decade, the immigrant population of the Balearic Islands archipelago (Spain), in the Mediterranean, has risen to 22% of its total population. The aim of this study was to assess food consumption patterns among Balearic Islands' adolescents depending on their origin. A population-based cross-sectional nutritional survey was carried out in the Balearic Islands (2007-2008; n = 1,231; 12-17 years old). Dietary assessment was based on a 145-item semi-quantitative food-frequency questionnaire. Food consumption differences between the adolescents' point of origin and time of arrival were been studied, as well as average daily meals and snacks. The adolescents' origin and number of years living in the Balearic Islands were also assessed. Native adolescents and immigrants from other Mediterranean countries showed healthier food consumption patterns than their peers from non-Mediterranean countries. Immigrant adolescents adapted their eating patterns to native dietary patterns increasingly, the longer they lived in the Balearic Islands. PMID:25012273

    We investigated the availability, preference, and consumption of indigenous forest foods in Uluguru North (UNM) and West Usambara Mountains (WUM) of Tanzania. Data collection techniques involved focus group discussion, structured questionnaires, and botanical identification. Results revealed (1) there were 114 indigenous forest food plant species representing 57 families used by communities living adjacent to the two mountains; (2) sixty-seven species supplied edible fruits, nuts and seeds: 24 and 14 species came from WUM and UNM, respectively, while 29 came from both study areas; (3) of the 57 identified vegetable species, 22 were found in WUM only, 13 in UNM only, and 12 in both areas; (4) there were three species of edible mushrooms and five species of roots and tubers; (5) unlike the indigenous roots and tubers, the preference and consumption of indigenous vegetables, nuts, and seeds/oils was higher than exotic species in both study areas; and (6) UNM had more indigenous fruits compared to WUM, although preference and consumption was higher in WUM. We recommend increased research attention on forest foods to quantify their contribution to household food security and ensure their sustainability. PMID:21883080

    Background: Type 2 diabetes is a major problem in Western nations. Profound secular changes in the food environment and eating habits may play a role. In particular, consumption of foods prepared outside the home has greatly increased. Objective: We investigated the relation of restaurant meal consumption to incidence of type 2 diabetes among African American women with the use of data from the prospective Black Women's Health Study. Design: The participants have completed mailed follow-up questionnaires every 2 y since 1995, including food-frequency questionnaires that asked about the frequency of eating restaurant meals of various types. Cox proportional hazards models were used to calculate incidence rate ratios and 95% CIs for the association of type 2 diabetes incidence with various categories of consumption of each restaurant food relative to the lowest category, with adjustment for diabetes risk factors. Results: Among 44,072 participants aged 30–69 y and free of diabetes at baseline, 2873 incident cases of type 2 diabetes occurred during 10 y of follow-up. Consumption of restaurant meals of hamburgers, fried chicken, fried fish, and Chinese food were independently associated with an increased risk of type 2 diabetes. Incidence rate ratios for ≥2 such meals per week relative to none were 1.40 (95% CI: 1.14, 1.73) for hamburgers and 1.68 (95% CI: 1.36, 2.08) for fried chicken. Control for body mass index greatly reduced the estimates, which suggests that the associations are mediated through weight gain and obesity. Conclusion: The present study has identified a risk factor for type 2 diabetes that may be readily modifiable by dietary changes. PMID:20016014

  17. Nutrition knowledge and food consumption: can nutrition knowledge change food behaviour?

    PubMed

    Worsley, Anthony

    2002-01-01

    The status and explanatory role of nutrition knowledge is uncertain in public health nutrition. Much of the uncertainty about this area has been generated by conceptual confusion about the nature of knowledge and behaviours, and, nutrition knowledge and food behaviours in particular. So the paper describes several key concepts in some detail. The main argument is that 'nutrition knowledge' is a necessary but not sufficient factor for changes in consumers' food behaviours. Several classes of food behaviours and their causation are discussed. They are influenced by a number of environmental and intra-individual factors, including motivations. The interplay between motivational factors and information processing is important for nutrition promoters as is the distinction between declarative and procedural knowledge. Consideration of the domains of nutrition knowledge shows that their utility is likely to be related to consumers' and nutritionists' particular goals and viewpoints. A brief survey of the recent literature shows that the evidence for the influence of nutrition knowledge on food behaviours is mixed. Nevertheless, recent work suggests that nutrition knowledge may play a small but pivotal role in the adoption of healthier food habits. The implications of this overview for public health nutrition are: (i) We need to pay greater attention to the development of children's and adults' knowledge frameworks (schema building); (ii) There is a need for a renewed proactive role for the education sector; (iii) We need to take account of consumers' personal food goals and their acquisition of procedural knowledge which will enable them to attain their goals; (iv) Finally, much more research into the ways people learn and use food-related knowledge is required in the form of experimental interventions and longitudinal studies.

    The mapping and analysis of supply chains is a technique increasingly used to address problems in the food system. Yet such supply chain management has not yet been applied as a means of encouraging healthier diets. Moreover, most policies recommended to promote healthy eating focus on the consumer end of the chain. This article proposes a consumption-oriented food supply chain analysis to identify the changes needed in the food supply chain to create a healthier food environment, measured in terms of food availability, prices, and marketing. Along with established forms of supply chain analysis, the method is informed by a historical overview of how food supply chains have changed over time. The method posits that the actors and actions in the chain are affected by organizational, financial, technological, and policy incentives and disincentives, which can in turn be levered for change. It presents a preliminary example of the supply of Coca-Cola beverages into school vending machines and identifies further potential applications. These include fruit and vegetable supply chains, local food chains, supply chains for health-promoting versions of food products, and identifying financial incentives in supply chains for healthier eating.

    The objective of this study was to test if proximity of a food or preference for a food influences food intake in a competitive food environment in which one low calorie/low fat (apple slices) and one higher calorie/higher fat (buttered popcorn) food was available in the same environment. The proximity of popcorn and apple slices was manipulated and 56 participants were randomly assigned to groups. In Group Apples Near, apple slices were placed near (within arms reach) a participant and popcorn was placed far (2m away). In Group Popcorn Near, buttered popcorn was placed near and apple slices were placed far. As a control for the absence of a proximity manipulation, Group Both Near had both test foods placed near. Although participants rated the popcorn as more liked than apples, the food that was placed closer to the participant was consumed most in the two experimental groups, regardless of preference (R(2)=0.38). Total energy intake was reduced most when popcorn was placed far from a participant compared to when it was placed near (R(2)=0.24). The effects reported here were not moderated by BMI and did not vary by sex. In all, the results support the hypothesis that making a low calorie food more proximate will reduce total energy intake and increase intake of a low calorie food, even when a higher calorie and more preferred food is also available, but less proximate.

    It is widely accepted that food consumption in humans declines with advanced age; however, data from mice remain controversial. Based on our previous observation that mice spill a considerable amount of food while eating, we hypothesized that increased food spillage in old mice masks actual food intake. To investigate whether mice exhibit age-associated declines in food consumption, we evaluated the actual food consumption of C57BL/6 mice at various ages by measuring both the amount of food in the food receptacle and the amount dropped to the cage bottom during feeding. We found that old mice dropped significantly more food (36% ± 8%) than young mice (18% ± 5%), which led to overestimations of food consumption, particularly in old mice. Although actual food consumption decreased in very old mice, food intake per body weight did not significantly change. These findings suggest that caution should be taken to accurately quantify food consumption by aged animals. PMID:22451471

    Childhood obesity is currently at its highest: recent statistics show that 16% of children between the ages of 6 and 11 y are overweight [> or =95th percentile of body mass index (BMI; in kg/m(2)) for age] and that an additional 14.3% are at risk of becoming overweight (> or =85th percentile but < 95th percentile of BMI for age). As children's body weights have increased, so has their consumption of fast foods and soft drinks. The proportion of foods that children consumed from restaurants and fast food outlets increased by nearly 300% between 1977 and 1996. Children's soft drink consumption has also increased during those years, and now soft drinks provide soft drink consumers 188 kcal/d beyond the energy intake of nonconsumers. These changes in food intakes among children may partly explain the rise in childhood obesity observed in the past few years. Although the mechanism of appetite regulation will not be explored in this report, it is hypothesized that the greater energy intakes in children who consume large amounts of soft drinks and fast foods are not compensated for by increased physical activity or decreased energy intakes. Furthermore, overweight and obesity in childhood may predispose persons to morbidity in adulthood. Blood pressure and fasting insulin and cholesterol concentrations are higher in overweight children than in normal-weight children. This review focuses on current food patterns and eating habits of children, in an attempt to explain their increasing BMI. In addition, a critical review of food service and political practices regarding food choices for children at school is included. PMID:14668265

    Increased intake of saturated fat and refined sugars underlies much of the problem of emerging obesity all over the world. This includes middle-income countries like Thailand, which are subject to successful marketing of Western fast foods especially targeted at adolescents. In this study we explore the socio-cultural influences on fast-food intake for non-metropolitan (rural and urban) adolescents in North East Thailand (Isan). Our questionnaire sample included 634 persons aged 15–19 years who are in and out of formal schooling and who are randomly representing upper, central and lower Isan. All were asked about their knowledge of fast-food health risks and their attitudes towards, and consumption of, fast food and traditional food. As well, we used several focus groups to obtain qualitative data to complement the information derived from the questionnaire. Some three quarters of sampled youth were aware that fast food causes obesity and half knew of the link to heart disease. About half consumed fast food regularly, induced by the appeal of ‘modern’ lifestyles, social events and marketing, as well as by the convenience, speed and taste. Nearly two-thirds thought that local foods should be more popular and these beliefs were more likely to be found among children from educated and urban families. Local foods already constitute a cultural resistance to fast-food uptake. We propose several methods to boost this resistance and protect the youth of Thailand against fast food and its many adverse health consequences. PMID:21547247

    Present patterns of food consumption in Sweden include a substantial amount of imported vegetables as well as meat. Such a diet may be questioned for sustainability because of its dependence on, for example, inputs of energy emissions of greenhouse gases during the production, transportation and storage of some selected food consumed in Sweden during 1993 are quantified here. Contributors to the selected impact category are energy related emissions, leakage of refrigerants, and emissions of nitrous oxides from farm land. Total emissions are calculated in grams of CO{sub 2} equivalents per capita and per kg product.

    The paper examines street foods consumption in the Market Circle of Sekondi-Takoradi, Ghana. The data used for the study were obtained from individuals who were either purchasing or consuming street foods in the Market Circle in August of 2011. The results revealed that the average consumer makes use of street foods six times in a week and there was a penchant for carbohydrate based foods over other types of street foods. Reasons including cost saving, convenience and eating on credit were noted to underlie the consumption of street foods in the area. Based on the findings, it was concluded that the high consumption of street foods in the Market Circle was for reasons other than nutrition and health. PMID:26341743

    Continuous monitoring of fluid changes using bioimpedance spectroscopy (BIS) during hemodialysis could help to predict hypotensive complications and extend the patient's life. Food and beverage consumption during the treatment may influence the measurements and the calculated fluid removal. In the present article the change observed in whole body and segmental (knee-to-knee, abdomen) BIS measurements following a sequence similar to the one of dialysis treatment (lying down, sitting and eating, lying down) on healthy subjects is presented. The measurements have been performed using a commercial bioimpedance device with a frequency range of 5 kHz to 1 MHz. Knee-to-knee measurements seem to be less sensitive to these influences, compared to the standard whole body and the alternative abdomen BIS measurements. The results indicate that the individual influence of both body posture and food and beverage consumption may be superposed when combined.

    Calcium intake is one of a number of factors that affect peak bone mass. Low bone mass is related to increased incidence of osteoporotic fractures. Data from the USDA 1987-88 Nationwide Food Consumption Survey were used to determine populations most at risk of less than optimal calcium intake and food sources of calcium intake. Mean per capita daily consumption of calcium for the total U.S. population was 737 mg and varied by region of the country, household income, ethnic group, sex, and age. For most groups of females, intake was substantially less than the RDA. About 50% of total dietary calcium was supplied by milk and milk products. Milk and cheese used as ingredients in meat, grain, and vegetable mixtures contributed another 20% of dietary calcium. The remaining 30% of calcium was provided by grains and grain products, meat, poultry, fish, vegetables, fruits, eggs, legumes, nuts, and seeds. PMID:8064396

    We examined feeding periodicity of three size groups of the rusty crayfish (Orconectes rusticus) at four-hour intervals over a 28-hour period during July in a headwater stream of the Susquehanna River drainage in central New York. Feeding activity was expressed as the ratio of stomach weight divided by the crayfish wet weight. The diel food consumption patterns of all three size groups of rusty crayfish (i.e., ≤ 10 mm, 11–20 mm, and > 20 mm carapace length) were significantly different. Peak feeding of the smallest crayfish occurred during crepuscular periods. Food consumption of the intermediate size crayfish was highest at 2000 h, and feeding of large crayfish was consistently high from 1200 h to 0400 h. Feeding intensity of both small and intermediate size crayfish was highest when feeding intensity of large crayfsh was lowest. Ontogenetic differences in feeding periodicity may be associated with predation pressure from large rusty crayfish on smaller individuals.

    Background: Although fast food consumption has been linked to adverse health outcomes, the relative contribution of fast food itself compared with the rest of the diet to these associations remains unclear. Objective: Our objective was to compare the independent associations with overweight/obesity or dietary outcomes for fast food consumption compared with dietary pattern for the remainder of intake. Design: This cross-sectional analysis studied 4466 US children aged 2–18 y from NHANES 2007–2010. Cluster analysis identified 2 dietary patterns for the non–fast food remainder of intake: Western (50.3%) and Prudent. Multivariable-adjusted linear and logistic regression models examined the association between fast food consumption and dietary pattern for the remainder of intake and estimated their independent associations with overweight/obesity and dietary outcomes. Results: Half of US children consumed fast food: 39.5% low-consumers (≤30% of energy from fast food) and 10.5% high-consumers (>30% of energy). Consuming a Western dietary pattern for the remainder of intake was more likely among fast food low-consumers (OR: 1.51; 95% CI: 1.24, 1.85) and high-consumers (OR: 2.21; 95% CI: 1.60, 3.05) than among nonconsumers. The remainder of diet was independently associated with overweight/obesity (β: 5.9; 95% CI: 1.3, 10.5), whereas fast food consumption was not, and the remainder of diet had stronger associations with poor total intake than did fast food consumption. Conclusions: Outside the fast food restaurant, fast food consumers ate Western diets, which might have stronger associations with overweight/obesity and poor dietary outcomes than fast food consumption itself. Our findings support the need for prospective studies and randomized trials to confirm these hypotheses. PMID:24153348

    Introduction: Obesity is a condition in which excess body fat accumulates, which leads to various adverse effects on health, particularly cardiovascular diseases (CVDs), which reduce life expectancy and/or increase health problems. Fast food consumption is one of the factors which have been reported as a cause of obesity. Body mass index (BMI) is used to assess obesity and overweight, which can be calculated by using the formula, weight in kg, divided by square of height in metres. Aim: This study focused on the relationship of body mass index with fast food consumption, associated soft drink consumption and physical activity. Methods: Descriptive cross-sectional study was conducted in Department of Biochemistry, SBKS MI and RC, and Sumandeep Vidyapeeth. This study was approved by the ethical review board .One hundred and forty seven medical students from 1st year MBBS course were included in this study. Self-structured questionnaire was used, which contained several data like information on age, height, weight, education level. The formula used for calculating BMI was, weight in kg, divided by square of height in metres (Kg/m2). Results: In our study, out of 147 students, a total of 138 students (more than 90%) used to have fast food. Among these, a total of 47 students (34.05%) were pre-obese and obese. Out of 147 students, 87 students (59.18%) were in normal weight range, while 13 (8.84%) students were underweight. Statistical Analysis: Data was compiled in an Excel worksheet and it was analyzed for percentages and proportions. Chi-square and Pearson’s correlation test were also applied wherever they were applicable and Alpha error was set at a 5% level. Conclusion: In our study, a significant relationship was found between BMI and fast food consumption, less physical activity, and intake of soft drinks. PMID:24995170

    The Food and Agriculture Organization of the United Nations estimates that 843 million people worldwide are hungry and a greater number suffer from nutrient deficiencies. Approximately one billion people have inadequate protein intake. The challenge of preventing hunger and malnutrition will become even greater as the global population grows from the current 7.2 billion people to 9.6 billion by 2050. With increases in income, population, and demand for more nutrient-dense foods, global meat production is projected to increase by 206 million tons per year during the next 35 years. These changes in population and dietary practices have led to a tremendous rise in the demand for food protein, especially animal-source protein. Consuming the required amounts of protein is fundamental to human growth and health. Protein needs can be met through intakes of animal and plant-source foods. Increased consumption of food proteins is associated with increased greenhouse gas emissions and overutilization of water. Consequently, concerns exist regarding impacts of agricultural production, processing and distribution of food protein on the environment, ecosystem, and sustainability. To address these challenging issues, the New York Academy of Sciences organized the conference "Frontiers in Agricultural Sustainability: Studying the Protein Supply Chain to Improve Dietary Quality" to explore sustainable innovations in food science and programming aimed at producing the required quality and quantity of protein through improved supply chains worldwide. This report provides an extensive discussion of these issues and summaries of the presentations from the conference. PMID:25123207

    Protein intakes in the older population can be lower than recommended for good health, and while reasons for low protein intakes can be provided, little work has attempted to investigate these reasons in relation to actual intakes, and so identify those of likely greatest impact when designing interventions. Questionnaires assessing: usual consumption of meat, fish, eggs and dairy products; agreement/disagreement with reasons for the consumption/non-consumption of these foods; and several demographic and lifestyle characteristics; were sent to 1000 UK community-dwelling adults aged 65 years and over. In total, 351 returned questionnaires, representative of the UK older population for gender and age, were suitable for analysis. Different factors were important for consumption of the four food groups, but similarities were also found. These similarities likely reflect issues of particular concern to both the consumption of animal-based protein-rich foods and the consumption of these foods by older adults. Taken together, these findings suggest intakes to be explained by, and thus that strategies for increasing consumption should focus on: increasing liking/tastiness; improving convenience and the effort required for food preparation and consumption; minimizing spoilage and wastage; and improving perceptions of affordability or value for money; freshness; and the healthiness of protein-rich foods.

    Davis, D E

    1976-12-01

    In order to understand better the evolution and adaptive value of hibernation, ecological aspects and experimental studies of closely related hibernators, the Marmotini, are examined. The central hypothesis is that annual changes in the environment integrate three or, perhaps, four physiological processes: torpor, reporduction, consumption of food, and metabolism. Reproduction occurs promptly after emergence from hibernation. For most species, the breeding season is very short. Although the experimental data are rather meager, no variation in external factors has consistently altered the season of reproduction. Consumption of food and change in weight increases until July or September and then decreases. The large members of the Marmotini store their energy as fat, but small species store their energy as seeds and nuts. Experiments to test the hypothesis that some aspect of the supply, such as fat content, might vary seasonally have produced negative results. Complex experiments on the length of the photoperiod on woodchucks and several species of ground squirrels failed to alter the annual cycle of consumption of food. Animals kept in constant conditions showed a cycle of about 11 months, but woodchucks sent tto Australia changed their cycle in two years to match the seasons of the southern hemisphere.

    The Korea Food and Drug Administration (KFDA) revised the Health Functional Food Act in 2008 and extended the form of health functional foods to general food types. Therefore, this study was performed to investigate consumers' perceptions of the expanded form of health functional food and to predict consumption patterns. For this study, 1,006 male and female adults aged 19 years and older were selected nationwide by multi-stage stratified random sampling and were surveyed in 1:1 interviews. The questionnaire survey was conducted by Korea Gallup. The subjects consisted of 497 (49.4%) males and 509 (50.6%) females. About 57.9% of the subjects recognized the KFDA's permission procedures for health functional foods. Regarding the health functional foods that the subjects had consumed, red ginseng products were the highest (45.3%), followed by nutritional supplements (34.9%), ginseng products (27.9%), lactobacillus-containing products (21.0%), aloe products (20.3%), and Japanese apricot extract products (18.4%). Opinions on expanding the form of health functional foods to general food types scored 4.7 points on a 7-point scale, showing positive responses. In terms of the effects of medicine-type health functional foods versus generic health functional foods, the highest response was 'same effects if the same ingredients are contained' at a rate of 34.7%. For intake frequency by food type, the response of 'daily consistent intake' was 31.7% for capsules, tablets, and pills, and 21.7% for extracts. For general food types, 'daily consistent intake' was 44.5% for rice and 22.8% for beverages, which were higher rates than those for medicine types. From the above results, consumers had positive opinions of the expansion of health functional foods to generic forms but are not expected to maintain accurate intake frequencies or amounts. Thus, continuous promotion and education are needed for proper intake of generic health functional foods. PMID:21994526

    2013-01-01

    Human foods typically contain a minor fraction of the nitrogen (N) used in agricultural production. The major fraction is lost to the environment and interferes with all current environmental problems and global change issues. Food is also generally consumed far from its production location and associated N losses remain unknown unless connected to products through consumption-based indicators. We develop the N food-print as an indicator to connect N flows and losses in livestock systems to the consumption of dietary N in the form of beef, pork and fresh milk in France. This N food-print of a product is the N loss associated with its agricultural production. The conversions of N, from field application to recovery in vegetal and animal proteins, are calculated from statistical data on crop and animal production and through modelling of feed rations for cattle and swine. Beef farming to feed an individual in France uses 11.1 kg N cap-1 yr-1, out of which 3.8 kg N cap-1 yr-1 (or 35%) is the N food-print, 7% is recovered in retail products, 3% is slaughter waste and 55% returns to agriculture as manure. Pork and dairy production use 7.5 and 2.3 kg N cap-1 yr-1, respectively, out of which 53 and 48% is the N food-print, respectively; about 11% is recovered in retail products and 35% returns to agriculture as manure. In total, more than 75% of the N food-print relates to crop cultivation for feed and much of these losses (80% for dairy and pork production, 20% for beef production) occur in crop farms far from where the livestock is reared. Regional and national policies to reduce N losses should take into account that trade in feed implies causal relationships among N losses in agrosystems distant from each other.

    Eating behavior can be influenced by the rewarding value of food, i.e., "liking" and "wanting." The objective of this study was to assess in normal-weight dietary restrained (NR) vs. unrestrained (NU) eaters how rewarding value of food is affected by satiety, and by eating a nonhealthy perceived, dessert-specific food vs. a healthy perceived, neutral food (chocolate mousse vs. cottage cheese). Subjects (24NR age = 25.0 ± 8.2 years, BMI = 22.3 ± 2.1 kg/m(2); 26NU age = 24.8 ± 8.0 years, BMI = 22.1 ± 1.7 kg/m(2)) came to the university twice, fasted (randomized crossover design). Per test-session "liking" and "wanting" for 72 items divided in six categories (bread, filling, drinks, dessert, sweets, stationery (placebo)) was measured, before and after consumption of chocolate mousse/cottage cheese, matched for energy content (5.6 kJ/g) and individual daily energy requirements (10%). Chocolate mousse was liked more than cottage cheese (P < 0.05). After consumption of chocolate mousse or cottage cheese, appetite and "liking" vs. placebo were decreased in NR and NU (P < 0.03), whereas "wanting" was only decreased in NR vs. NU (P ≤ 0.01). In NR vs. NU "wanting" was specifically decreased after chocolate mousse vs. cottage cheese; this decrease concerned especially "wanting" for bread and filling (P < 0.05). To conclude, despite similar decreases in appetite and "liking" after a meal in NR and NU, NR decrease "wanting" in contrast to NU. NR decrease "wanting" specifically for a nonhealthy perceived, "delicious," dessert-specific food vs. a nutritional identical, yet healthy perceived, slightly less "delicious," "neutral" food. A healthy perceived food may thus impose greater risk for control of energy intake in NR. PMID:20186140

    Common eider Somateria mollissima L. 1758, subsp. borealis, is widely distributed along the coasts of Iceland. In this study association of parasite infections and food composition was studied among 40 females and 38 males (66 adults, 12 subadults), shot under license on four occasions within the same year (February; before egg-laying in May; after the breeding period in late June; and in November) in Skerjafjörður, SW Iceland. Parasitological examinations revealed 31 helminth species (11 digeneans, ten cestodes, seven nematodes, and three acanthocephalans). Distinct digenean species parasitized the gallbladder, kidney and bursa of Fabricius, whereas other helminths parasitized the gastrointestinal tract. Thirty-six invertebrate prey species were identified as food; waste and bread fed by humans, were also consumed by some birds. Amidostomum acutum was the only parasite found with a direct life cycle, whereas other species were food transmitted and ingested with different invertebrate prey. Opposite to females male birds rarely utilized periwinkles and gammarids as a food source. As a result, Microphallus and Microsomacanthus infection intensities were low except in February, when subadult males were responsible for an infection peak. Females caring for young increased their consumption of periwinkles close to the littoral zone in June; during pre-breeding, females also increased their gammarid intake. As a consequence, Microphallus and Microsomacanthus infection intensities temporarily peaked. Increased food intake (including Mytilus edulis) of females before the egg-laying period resulted in twofold higher Gymnophallus bursicola infection intensity than observed for males. Profilicollis botulus infection reflected seasonal changes in decapod consumption in both genders. Different life history strategies of males and females, especially before and during the breeding season and caring of young, and during molting in distinct feeding areas in summer, promote

    Obesity is a substantial health problem in the United States, and is associated with many chronic diseases. Previous studies have linked poor dietary habits to obesity. This cross-sectional study aimed to identify the association between body mass index (BMI) and fast-food consumption among 669 same-sex adult twin pairs residing in the Puget Sound region around Seattle, Washington. We calculated twin-pair correlations for BMI and fast-food consumption. We next regressed BMI on fast-food consumption using generalized estimating equations (GEE), and finally estimated the within-pair difference in BMI associated with a difference in fast-food consumption, which controls for all potential genetic and environment characteristics shared between twins within a pair. Twin-pair correlations for fast-food consumption were similar for identical (monozygotic; MZ) and fraternal (dizygotic; DZ) twins, but were substantially higher in MZ than DZ twins for BMI. In the unadjusted GEE model, greater fast-food consumption was associated with larger BMI. For twin pairs overall, and for MZ twins, there was no association between within-pair differences in fast-food consumption and BMI in any model. In contrast, there was a significant association between within-pair differences in fast-food consumption and BMI among DZ twins, suggesting that genetic factors play a role in the observed association. Thus, although variance in fast-food consumption itself is largely driven by environmental factors, the overall association between this specific eating behavior and BMI is largely due to genetic factors.

    This study evaluated the trophic ecology (diet composition, trophic strategy, similarities and overlap between species, feeding period and food consumption) of six benthivorous fish species in Araruama Lagoon, the largest hypersaline tropical lagoon on the east coast of South America, with an area of 210 km(2) and an average salinity of 52. The burrfish Chilomycterus spinosus fed on Anomalocardia flexuosa shell deposits, ingesting associated fauna. The caitipa mojarra Diapterus rhombeus differed from all other species, having not only the highest proportions of algae and Nematoda, but also feeding on polychaete tentacles. The two mojarras Eucinostomus spp. showed similar trophic strategies, feeding mostly on Polychaeta. The corocoro grunt Orthopristis ruber also fed mainly on Polychaeta, but differed from Eucinostomus spp. in secondary items. The whitemouth croacker Micropogonias furnieri fed mainly on small Crustacea at night, showing a high number of secondary prey items with low frequencies and high prey-specific abundance. The daily food consumption (g food g(-1) fish mass) for Eucinostomus argenteus was 0·012 and was 0·031 and 0·027 for M. furnieri in two different sampling events. The diet similarities between Araruama Lagoon and other brackish and marine environments indicate that hypersalinity is not a predominant factor shaping the trophic ecology of fishes in this lagoon. The stability of hypersaline conditions, without a pronounced gradient, may explain the presence of several euryhaline fishes and invertebrates well adapted to this condition, resulting in a complex food web.

    Policies that mandate calorie labeling in fast-food and chain restaurants have had little or no observable impact on calorie consumption to date. In three field experiments, we tested an alternative approach: activating consumers' self-control by having servers ask customers if they wanted to downsize portions of three starchy side dishes at a Chinese fast-food restaurant. We consistently found that 14-33 percent of customers accepted the downsizing offer, and they did so whether or not they were given a nominal twenty-five-cent discount. Overall, those who accepted smaller portions did not compensate by ordering more calories in their entrées, and the total calories served to them were, on average, reduced by more than 200. We also found that accepting the downsizing offer did not change the amount of uneaten food left at the end of the meal, so the calorie savings during purchasing translated into calorie savings during consumption. Labeling the calorie content of food during one of the experiments had no measurable impact on ordering behavior. If anything, the downsizing offer was less effective in changing customers' ordering patterns with the calorie labeling present. These findings highlight the potential importance of portion-control interventions that specifically activate consumers' self-control. PMID:22323171

    Greenhouse gas (GHG) emissions from agriculture could be mitigated from both supple side and demand side. Assessing carbon footprint (CF) of agricultural production and food consumption could provide insights into the contribution of agriculture to climate change and help to identify possible GHG mitigation options. In the present study, CF of China's agricultural production was firstly assessed from site scale to national scale, and from crop production to livestock production. Data for the crop and livestock production were collected from field survey and national statistical archive, and both life cycle assessment and input-output method were employed in the estimations. In general, CF of crop production was lower than that of livestock production on average. Rice production ranked the highest CF in crop production, and the highest CFs of livestock production were observed in mutton and beef production. Methane emissions from rice paddy, emissions from fertilizer application and water irrigation exerted the largest contribution of more than 50% for CF of crop production; however, emissions from forage feeding, enteric fermentation and manure treatment made the most proportion of more than 90 % for CF of livestock production. In China, carbon efficiency was shown in a decreasing trend in recent years. According to the present study, overuse of nitrogen fertilizer caused no yield effect but significant emissions in some sites and regions of China, and aggregated farms lowered the CFs of crop production and livestock production by 3% to 25% and 6% to 60% respectively compared to household farms. Given these, improving farming management efficiency and farm intensive development is the key strategy to mitigate climate change from supply side. However, changes in food consumption may reduce GHG emissions in the production chain through a switch to the consumption of food with higher GHG emissions in the production process to food with lower GHG emissions. Thus, CFs

    Background The increasing consumption of sugar worldwide seems to lead to several health problems, including some types of cancer. While some studies reported a positive association between sweet foods intake and breast cancer risk, little is known about their relation to mammographic density (MD), a strong breast cancer risk factor. This study examined the association of sweet foods and drinks intake with MD among 776 premenopausal and 779 postmenopausal women recruited at mammography. Methods A food-frequency questionnaire was used to assess intake of sweet foods, sugar-sweetened beverages and spoonsful of sugar added. Percent and absolute breast density were estimated using a computer-assisted method. Multivariate generalized linear models were used to evaluate associations. All models were adjusted for potential confounders, including age and body mass index. Results For increasing quartiles of sugar-sweetened beverages intake, adjusted-mean absolute density was respectively 32, 34, 32 and 36 cm2 among all women (Ptrend = 0.040) and 43, 46, 44 and 51 cm2 among premenopausal women (Ptrend = 0.007). For increasing quartiles of sweet foods intake, adjusted-mean percent density was respectively 16, 16, 17 and 19% among postmenopausal women (Ptrend = 0.036). No association was shown between intake of spoonsful of sugar added and MD. Conclusion Our results suggest that an increase in sweet foods or sugar-sweetened beverage intake is associated with higher MD. PMID:24969543

    Smartphone "apps" are a powerful tool for public health promotion, but unidimensional interventions have been ineffective at sustaining behavioural change. Various logistical issues exist in successful app development for health intervention programs and for sustaining behavioural change. This study reports on a smartphone application and messaging service, called "SmartAPPetite," which uses validated behaviour change techniques and a behavioural economic approach to "nudge" users into healthy dietary behaviours. To help gauge participation in and influence of the program, data were collected using an upfront food survey, message uptake tracking, experience sampling interviews, and a follow-up survey. Logistical and content-based issues in the deployment of the messaging service were subsequently addressed to strengthen the effectiveness of the app in changing dietary behaviours. Challenges included creating relevant food goal categories for participants, providing messaging appropriate to self-reported food literacy and ensuring continued participation in the program. SmartAPPetite was effective at creating a sense of improved awareness and consumption of healthy foods, as well as drawing people to local food vendors with greater frequency. This work serves as a storehouse of methods and best practices for multidimensional local food-based smartphone interventions aimed at improving the "triple bottom line" of health, economy, and environment.
