    Niederpruem, Donald J. (Indiana University Medical Center, Indianapolis), Hudner Hobbs, and Lyle Henry. Nutritional studies of development in Schizophyllum commune. J. Bacteriol. 88:1721–1729. 1964.—Individual carbon and nitrogen sources which sustain dikaryotic fruiting in the basidiomycete Schizophyllum commune were determined. Combination studies indicated that certain poor substrates were inhibitory; these included acetate, citrate, KNO2, and l-lysine. Homokaryotic (haploid) fruiting was promoted by dilute culture medium. Both developmental systems were arrested by respiratory CO2. Elevated temperature (e.g., 30 C) essentially completely blocked homokaryotic fruiting of S. commune. Images PMID:14240962

    Nutrition is one of the most important factors affecting pubertal development. Puberty entails a progressive nonlinear process starting from prepubescent to full sexual maturity through the interaction and cooperation of biological, physical, and psychological changes. Consuming an adequate and balanced healthy diet during all phases of growth (infancy, childhood and puberty) appears necessary both for proper growth and normal pubertal development. Girls begin puberty at an earlier age compared to past decades. Excessive eating of many processed, high-fat foods, may be the cause of this phenomenon. Overweight or obese children are more likely to enter puberty early. Some evidence suggests that obesity can accelerate the onset of puberty in girls and may delay the onset of puberty in boys. Moreover, the progression of puberty is affected by nutrition. On the other hand, puberty triggers a growth spurt, which increases nutritional needs including macro and micronutrients. Increased caloric, protein, iron, calcium, zinc and folate needs have to be provided during this critical period of rapid growth. Severe primary or secondary malnutrition also can delay the onset and progression of puberty. The higher incidence of anorexia nervosa and bulimia in adolescents imposes a nutritional risk on pubertal development. Moreover, many environmental endocrine disruptors (EDs) have been identified that can significantly impair the normal course of puberty. This mini-review sums up some important findings in this important complex that link nutrition and pubertal development. PMID:25538876

    Detailed metabolic studies were conducted of the Apollo 16 and Apollo 17 flight crews, and the results are presented in tabular form. Intake and absorption data are also included. Apollo nutrient intakes were found to be characteristically hypocaloric. Estimates of body composition changes from metabolic balance data, from preflight and postflight weights and volumes, and from total body water and potassium provide no evidence for diminished caloric requirements during a flight. As observed during the Gemini Program and during periods of bed rest, measurements of bone density and metabolic balance confirm a tendency toward loss of skeletal tissue in weightlessness. No evidence exists that any inflight metabolic anomaly, including hypokalemia, was induced by marginal or deficient nutrient intakes. In general, the Apollo crewmen were well nourished and exhibited normal gastroenterological functions, although appetite was somewhat diminished and the organoleptic response to food was somewhat modified during flight.

    Health care service markets in general and hospital care service markets in particular are characterized by many competitive developments. Hence, hospital marketing managers are forced to respond to these emerging competitive pressures. However, in formulating appropriate marketing management strategies, hospital managers need to have detailed knowledge about consumers and their behaviors in the marketplace. This paper focuses on the Nutrition Care division of the Department of Nutrition Service at a hospital and its venture into new service development. This case study is intended to emphasize the significance of acquiring adequate knowledge of customers in the health care services industry. It particularly emphasizes the critical role that this type of information concerning customer behavior plays in the development and implementation of an appropriate business expansion strategy. Furthermore, the aim of this case study is to help the reader to relate the acquired marketing information to the problem at hand, and make the appropriate marketing management decision.

    Precise nutritional specifications arising from both physiological and experimental requirements necessitated a comprehensive study of the chemical composition of the Skylab food supply. Each of the approximately seventy different food items was analyzed for digestible and non-digestible carbohydrate, and for protein, amino acids, fat, fatty acids, vitamins and minerals. Menus were formulated to provide at least the National Research Council's Recommended Dietary Allowance of all essential nutrients and, in addition, to provide constant daily intakes of calcium, phosphorus, magnesium, sodium, potassium and protein. In general, the crew members adhered to their programmed menus. The ability to swallow and digest food was unaffected by prolonged weightlessness. Taste acuity also appeared to be undiminished in flight. The bone and muscle changes which occurred in previous flights were more pronounced in Skylab. It is concluded that these changes did not develop as a result of nutritional deficit. If such changes are nutritionally related, they point to the existence of nutritional requirements in weightlessness which differ quantitatively from those observed on earth.

    Maternal consumption of fish during the gestational period exposes the fetus to both nutrients, especially the long-chain polyunsaturated fatty acids (LCPUFAs), believed to be beneficial for fetal brain development, as well as to the neurotoxicant methylmercury (MeHg). We recently reported that nutrients present in fish may modify MeHg neurotoxicity. Understanding the apparent interaction of MeHg exposure and nutrients present in fish is complicated by the limitations of modeling methods. In this study we fit varying coefficient function models to data from the Seychelles Child Development Nutrition Study (SCDNS) cohort to assess the association of dietary nutrients and children’s development. This cohort of mother-child pairs in the Republic of Seychelles had fish consumption averaging 9 meals per week. Maternal nutritional status was assessed for five different nutritional components known to be present in fish (n-3 LCPUFA, n-6 LCPUFA, iron status, iodine status, and choline) and associated with children’s neurological development. We also included prenatal MeHg exposure (measured in maternal hair). We examined two child neurodevelopmental outcomes (Bayley Scales Infant Development-II (BSID-II) Mental Developmental Index (MDI) and Psychomotor Developmental Index (PDI)), each administered at 9 and at 30 months. The varying coefficient models allow the possible interactions between each nutritional component and MeHg to be modeled as a smoothly varying function of MeHg as an effect modifier. Iron, iodine, choline, and n-6 LCPUFA had little or no observable modulation at different MeHg exposures. In contrast the n-3 LCPUFA docosahexaenoic acid (DHA) had beneficial effects on the BSID-II PDI that were reduced or absent at higher MeHg exposures. This study presents a useful modeling method that can be brought to bear on questions involving interactions between covariates, and illustrates the continuing importance of viewing fish consumption during pregnancy as a

    We conducted a systematic review of studies that examined the effect of interventions combining a child development component with a nutrition one; in some cases the nutrition interventions also included health-promotion components. Only papers with both child development and nutrition outcomes and rated as moderate-to-good quality were included. Eleven efficacy and two nonrandomized trials, and eight program evaluations were identified. Only six trials examined interventions separately and combined. The trials showed nutritional interventions usually benefited nutritional status and sometimes benefited child development. Stimulation consistently benefited child development. There was no significant loss of any effect when interventions were combined, but there was little evidence of synergistic interaction between nutrition and stimulation on child development. Only three trials followed up the children after intervention. All at-scale program evaluations were combined interventions. Five benefited child development, but one did not, and two showed deficits. There was generally little benefit of at-scale programs to nutritional status. We found no rigorous evaluations of adding stimulation to health and nutrition services at scale and there is an urgent need for them. There is also a need to establish quality-control mechanisms for existing scaled-up programs and to determine their long-term effects. There is also a need to determine if there are any sustained benefits for the children after programs finish.

    Malnutrition permeates all aspects of health, growth, cognition, motor and social development of young children in developing countries. More than 50% of deaths in these children can be attributed to malnutrition, most often in conjunction with serious infection. Irreversible and lifelong sequelae prevent children from reaching their full potential. Child survival initiatives and programs have accomplished much to save the lives of children from common and preventable illnesses, but the quality of the survivors' health needs to be improved, with much more attention paid to nutrition of the preschool and school child. Promotion of nutritional health must become an integral part of primary health services, especially for infants, preschoolers, schoolchildren, and women. Promotion of exclusive breastfeeding and appropriate complementary feeding and weaning are essential inputs. A daunting challenge is to improve diet quality through the raising and consumption of small animals by rural subsistence households to enhance maternal and child nutrition. School feeding from preschool onward must be an integral part of education so children are in a condition to learn. An excellent example of such programs is the WHO initiated Integrated Management of Childhood Illness, which integrates nutrition into the care of both sick and well children. The Early Child Development Program initiated by the World Bank and UNICEF has taken hold in many countries. Nutrition outcomes are closely linked with health and education activities starting in the preconception period through pregnancy, lactation, and childhood. Investment in human capital early in life will optimize the growth and social and economic development of children, families, and communities.

By contrasting an historical analysis of the politicoeconomic development of agriculture and nutrition in the southern Cauca Valley with the assumptions guiding U.S. intervention in the health field there, a more complete picture of the causes of malnutrition is obtained, among which should be counted the intervention of the U.S. itself. Inter alia, other approaches to the malnutrition problem are suggested.

    There is increasing evidence to suggest that prenatal nutritional factors may have long-term effects on the offspring. Osteoporosis is a worldwide public health problem leading to both morbidity and mortality, through associated bone fractures. Although in clinical practice most effort in fracture prevention is aimed at slowing the rate of age-related bone loss, there is accumulating evidence that peak bone mass, achieved in early adulthood, is an important factor in determining bone strength in later life. A variety of studies have shown that peak bone mass is influenced by early life events, including nutrition in the prenatal period. This chapter will use the example of bone development to consider the effects of maternal diet and nutritional status on the offspring. PMID:23428680

    The importance of nutrition to public health and preventive medicine is evident. Undernutrition is a main nutritional risk factor in the elderly and has been established as a cause of excess morbidity and mortality in different segments of the older population. In the infant population, inadequate nutrition is one of the causes of iron-deficiency anemia, which is associated with impaired physical and cognitive development and lowered immunity. The aim of this paper was to estimate the nutritional pattern and micronutrient deficiencies in elderly and young populations in the Negev. In southern Israel, 351 subjects over 64 years old reported mean dietary intake that was lower than that in younger persons and was independent of the presence of chronic diseases. Current data from southern Israel on healthy Jewish children revealed anemia prevalence of 15% in the second year of life. Data from recent prospective study on Bedouin children showed that anemia affected one quarter of children at age one year. Thus, infants in this area are at high risk for iron deficiency. The findings require the attention of public health authorities and food manufacturers, and should result in a range of activities including publicity and educational programs, fortification of foods, and supplementation programs in high risk-groups.

    The nutrition of older people in developing countries, and the effect of their nutritional status on the quality of life, have not received sufficient attention. A 1997 symposium held at the London (England) School of Hygiene and Tropical Medicine addressed the assessment of nutritional vulnerability in older people in rural and urban settings. Reported were the results of a collaborative study conducted in the urban slums of Mumbai, India; a refugee camp for Rwandans in Karagwe, Tanzania; and rural communities in Malawi. Physical impairment was highest in India and increased with both age and deteriorating nutritional status in all three settings. Among the risk factors for nutritional vulnerability identified through the study to date are living alone, social isolation, reduced food intake, illiteracy, low socioeconomic status, and certain diseases. A field handbook to assess nutritional vulnerability has been prepared based on the research program and will be published in 1988. PMID:12293175

    Mentoring programs in nutrition are essential to the survival of clinical nutrition as we know it today. The best method known to maintain an influx of talent to a discipline is by developing an active mentoring program. This paper describes 1 concept for development of a viable mentor program. Mentoring should be flexible and based on mentees' training background. Realistic goals should be set, with written and verbal feedback, to sustain a successful program. Programs should incorporate the Socratic Method whenever possible. Factors that leave doubt about the survival of nutrition as a viable area of focus for physicians include the inability to generate adequate funds to support oneself and limited numbers of mentors available with dedicated time to be a mentor. A healthy, sustainable mentoring program in clinical nutrition will ensure survival of physician-based nutrition programs.

    Limited human data are available to assess the association between prenatal mercury vapor (Hg⁰)) exposure from maternal dental amalgam restorations and neurodevelopment of children. We evaluated the association between maternal dental amalgam status during gestation and children's neurodevelopmental outcomes at 5 years in the Seychelles Child Development Nutrition Study (SCDNS). Maternal amalgam status was determined prospectively in a longitudinal cohort study examining the associations of prenatal exposure to nutrients and methylmercury (MeHg) with neurodevelopment. A total of 236 mother-child pairs initially enrolled in the SCDNS in 2001 were eligible to participate. Maternal amalgam status was measured as number of amalgam surfaces (the primary metric) and number of occlusal points. The neurodevelopmental assessment battery was comprised of age-appropriate tests of cognitive, language, and perceptual functions, and scholastic achievement. Linear regression analysis controlled for MeHg exposure, maternal fatty acid status, and other covariates relevant to child development. Maternal amalgam status evaluation yielded an average of 7.0 surfaces (range 0-28) and 11.0 occlusal points (range 0-40) during pregnancy. Neither the number of maternal amalgam surfaces nor occlusal points were associated with any outcome. Our findings do not provide evidence to support a relationship between prenatal exposure to Hg⁰ from maternal dental amalgam and neurodevelopmental outcomes in children at 5 years of age.

    Nutrition is now becoming once more of intense interest to biological and medical scientists working on the control of development and human health. It is also now of ever greater public health interest. Few scientists, however, recognize that the same interest for those involved in fundamental science and public health developed a century ago focusing on the way in which nutrition and specific micronutrients, as well as general energy and protein intakes, were crucial to infant growth and appropriate development. The discovery of vitamins was matched by the proposition that stunted children in poor communities in the Western world were suffering from poverty-related poor diets. The critical role of nutrition was established by feeding studies, which then led to major food and agricultural policy changes during the Second World War, when food supplies were scarce throughout Europe. The success of these wartime policies led to a revolution in governmental thinking and a cheap food policy, together with a major boost in national agricultural production as an issue of national security. Nutritionists transferred their scientific interest to the study of childhood malnutrition in the developing world. The promotion of intensive agriculture and the food industry led to a revolution in food supplies, with the intense promotion of meat, milk, butter, and sugar production and consumption. The resulting escalation in cardiovascular disease related to the dietary change slowly altered public health policies, but as cardiovascular deaths decreased in the developed world, obesity and diabetes progressively increased. Now the lower- and middle-income countries (i.e., the developing world) have far more cardiovascular disease as Western diets and cultural habits are imported. The remarkable escalation of diabetes and cardiovascular disease, particularly in populations currently and previously subjected to malnutrition, now reveals unusual susceptibility to these diseases.

    Nutrition is now becoming once more of intense interest to biological and medical scientists working on the control of development and human health. It is also now of ever greater public health interest. Few scientists, however, recognize that the same interest for those involved in fundamental science and public health developed a century ago focusing on the way in which nutrition and specific micronutrients, as well as general energy and protein intakes, were crucial to infant growth and appropriate development. The discovery of vitamins was matched by the proposition that stunted children in poor communities in the Western world were suffering from poverty-related poor diets. The critical role of nutrition was established by feeding studies, which then led to major food and agricultural policy changes during the Second World War, when food supplies were scarce throughout Europe. The success of these wartime policies led to a revolution in governmental thinking and a cheap food policy, together with a major boost in national agricultural production as an issue of national security. Nutritionists transferred their scientific interest to the study of childhood malnutrition in the developing world. The promotion of intensive agriculture and the food industry led to a revolution in food supplies, with the intense promotion of meat, milk, butter, and sugar production and consumption. The resulting escalation in cardiovascular disease related to the dietary change slowly altered public health policies, but as cardiovascular deaths decreased in the developed world, obesity and diabetes progressively increased. Now the lower- and middle-income countries (i.e., the developing world) have far more cardiovascular disease as Western diets and cultural habits are imported. The remarkable escalation of diabetes and cardiovascular disease, particularly in populations currently and previously subjected to malnutrition, now reveals unusual susceptibility to these diseases.

    The purpose of this study was to observe early lesions of rat epiphyseal plates and metaphysis caused by T-2 toxin and T-2 toxin combined with a low nutrition diet to determine possible pathogenic factors of Kashin-Beck disease (KBD). Ninety Wistar rats were divided into three groups. Group A was fed with a normal diet as control; group B was fed with a normal diet and T-2 toxin; and group C was fed with a low nutrition diet and T-2 toxin. The left knee specimens were collected, fixed in formaldehyde solution, stained by hematoxylin and eosin and Masson. After two weeks, the epiphyseal plate showed necrosis of chondrocytes in groups B and C. After four weeks, more obvious chondrocyte necrosis appeared. The positive rate of Lamellar necrosis in group C was significantly higher than that in groups B and A (P < 0.01). Metaphyseal trabecular bone showed sparse disorder and disruption in group C. T-2 toxin combined with a low nutrition diet could lead to more serious chondrocyte necrosis in the epiphyseal plate and disturb metaphyseal trabecular bone formation.

    Fetal growth retardation due to maternal malnutrition is widespread especially in the Third World. Little is known about the mechanisms that regulate the growth of the fetus and placenta during protein malnutrition. It is known that the placental size and levels of circulating placental hormones such as human chorionic gonadotrophins (hCG), human placental lactogen (hPL), and estrogens are affected by the nutritional status of the mother. There is suggestive evidence that during malnutrition, hPL may increase lipolysis and exert a glucose sparing effect in the mother, thereby promoting glucose availability to the fetus. We have studied the influence of dietary protein deficiency on the binding of dexamethasone to the specific cytosol receptors in adult and fetal tissues. A low protein diet in adult male rats is associated with a decrease in dexamethasone binding to liver cytosol receptors. On the other hand, protein deprivation in pregnant female rats leads to an increase in dexamethasone binding to liver cytosol receptors of both the mother and fetus. However, the influences of maternal protein deprivation on dexamethasone receptors in the fetal liver and lungs are not similar. At 21 days gestation the binding of dexamethasone to fetal lung receptors of protein-deficient mothers is lower than that in the controls. These differences at a critical time in the fetal lung development indicate that a fall in receptors for dexamethasone may lead to impaired phospholipid synthesis in fetuses of protein-deficient mothers and point to the importance of nutritional factors in the biochemistry of fetal development.

    This study was designed to explore the nutritional value of proteins derived from algal biomasses of genus Spirulina maxima, with a view to the possible use of such proteins in human alimentation. Recently the use of such biomasses has commanded attention both as an alternative source of alimentary protein and as a coadjuvant in diet treatment requiring a reduced caloric intake - this because these substances seem to prolong gastric transit time and so produce a feeling of satiety. Our research was conducted in young growing rats; it provided confirmation of the validity of Spirulina as a protein source in terms of good weight gains by the test animals and freedom from adverse effects; the same research, on the other hand, failed to confirm the effectiveness of these protein materials in reducing caloric intake: throughout the test period, indeed, feed consumption (hence caloric intake) was practically the same in the control lot and in animals receiving Spirulina protein.

    The value of the zebrafish model has been well established. However, culture variability within and among laboratories remains a concern, particularly as it relates to nutrition. Investigators using rodent models addressed this concern several decades ago and have developed strict nutritional regimes to which their models adhere. These investigators decreased the variability associated with nutrition in most studies by developing standardized reference and open formulation diets. Zebrafish investigators have not embraced this approach. In this article, we address the problems associated with the lack of nutritional information and standardization in the zebrafish research community. Based on the knowledge gained from studies of other animals, including traditional research models, other fish species, domesticated and companion animals, and humans, we have proposed an approach that seeks to standardize nutrition research in zebrafish. We have identified a number of factors for consideration in zebrafish nutrition studies and have suggested a number of proposed outcomes. The long term-goal of nutrition research will be to identify the daily nutritional requirements of the zebrafish and to develop appropriate standardized reference and open formulation diets.

    Evidence of health disparities has been reported around the world. One of the intermediate factors between socioeconomic status (SES) and health is nutrition. Many studies reported socioeconomically disadvantaged people had more risk of obesity and lifestyle-related diseases than others in western society. Micronutrient intake affected by SES, but little evidence indicates that SES affects either energy intake or the macronutrient composition of the diet in western countries. In contrast, there is not enough evidence of a consistent relationship between SES and nutrition in Asian countries at present. The present status of nutrition disparities in Asia is considered to vary by economic level of the country. For developing countries in Asia, India and Vietnam, SES associates with BMI positively in women. For relatively developed countries in Asia, Korea and Japan, SES associates with BMI negatively in women. Low SES groups consume more carbohydrate, and less protein and fat, so not only micronutrient but also macronutrient intake is affected by SES both in developing and in developed Asian countries. There are some studies on the pathway from SES to diet/nutrition. The association between low SES and obesity may be mediated, in part, by the low cost of energy-dense foods, concern about food price and dietary knowledge. Nutrition policy research is required to reduce nutrition disparities in Asia. We need a collaborative study of the impact of potential political options on diet and on health with other academic fields. PMID:26598891

    Nutrition appeared somewhat late on the scene in the I.B.P. projects in the U.K., but eventually it occupied an integral part of many of the H.A. (human adaptability) investigations. The nutritional data obtained in the studies of isolated and nearisolated communities in Tristan da Cunha and in New Guinea provided information of wide nutritional significance. There were also detailed and extensive studies in Israel which, similarly to those in New Guinea, attempted to relate nutritional factors to enviroment, working conditions, and physical fitness. Some extraordinarily low energy intakes found in Ethiopians have induced much speculation on the extent which man can adequately adapt to restricted food supplies. Interesting nutritional observations, of general importance, have also arisen from results obtained on such disparate groups as Glasgow adolescents, Tanzanian and Sudanese students, children in Malawi and vegans in the U.K.

    One of the important roles of pharmacists as members of a nutrition support team is nutritional prescription support. We developed a nutritional prescription support system (NPSS) that facilitates prescription support and analysis and evaluated its usefulness in nutritional therapy. An NPSS for prescription support and the management of patient information was created. With this NPSS, the nutritional status was assessed, and, on the basis of the results, such variables as the total energy expenditure were calculated. This system allows prescription support for parenteral nutrition (PN) therapy, enteral nutrition (EN) therapy, and the transition period between them. This system was used for 2 representative patients and evaluated. In a malnourished patient receiving oral warfarin, EN solutions were compared by means of the NPSS, and an appropriate EN solution was selected. In addition, the prothrombin time-international normalized ratio was monitored, and favorable results were obtained regarding the adjustment of the warfarin dose and nutritional management. In a patient with aspiration pneumonia, continuous nutritional management to EN from PN therapy was straightforwardly performed with the NPSS. This NPSS allows rapid, comprehensive nutritional management during the transition period to EN from PN therapy, despite these therapies being considered separately in conventional nutritional management. The NPSS is useful for simplifying prescription support and facilitating information sharing among members of a nutrition support team.

    Socioemotional development in early childhood has long-term impacts on health status and social outcomes, and racial and socioeconomic disparities in socioemotional skills emerge early in life. The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) is an early childhood nutrition intervention with the potential to ameliorate these disparities. Our objective was to assess the impact of WIC on early socioemotional development in a longitudinal study. We examined the association between WIC participation and scores on the Brief Infant Toddler Social Emotional Assessment (BITSEA) in 327 predominantly African American mother-child dyads who were participants in the longitudinal Conditions Affecting Neurocognitive Development in Early Life (CANDLE) Study (Memphis, TN). To account for selection bias, we used within-child fixed effects to model the variability in each child's BITSEA scores over two measurement occasions (ages 12 and 24 months). Final models were adjusted for time-varying characteristics including child age, maternal stress, mental health, child abuse potential, marital status, and food stamp participation. In fully adjusted models, we found no statistically significant effect of WIC on change in socioemotional development (β = 0.22 [SD = 0.39] and β = - 0.58 [SD = 0.79] for BITSEA Competence and Problem subdomains, respectively). Using rigorous methods and a longitudinal study design, we found no significant association between WIC and socioemotional development in a high needs population. This finding suggests that early childhood interventions that more specifically target socioemotional development are necessary if we are to reduce racial disparities in socioemotional skills and prevent poor social and health outcomes across the life course.

    2014-03-01

    Using a sociological approach that elaborates on key observations of institutional entrepreneurs in international nutrition, this paper explores institutional boundaries and boundary work in international nutrition. Sociological concepts of "boundary making" and "situated knowledge" are applied to the boundaries between the nutrition sciences and lay nutrition knowledge in nutrition intervention. These concepts allow an analysis of how nutrition science creates boundaries between its field and other sciences and between nutrition as a science and other nutrition practices, providing additional perspective on current challenges in global food security and malnutrition. Analysis of boundary processes in international nutrition can also illuminate the development of "implementation" or "delivery science" in the field of international nutrition as it attempts to strengthen effectiveness of global efforts to reduce malnutrition. Although some risk taking in the academic world is rewarded, the analysis indicates that there are underlying processes that may inhibit full partnership with local people in the course of intervention work that builds scientific nutrition knowledge. As nutrition science becomes increasingly central to development, the boundaries that are reinforced by digging in heels over the implementation of programs with little local input or softened by inviting local stakeholders to publicly consider the problems in global nutrition together are important to consider in helping to create directions that favor viable solutions.

    Heifer development depends on nutritional management decisions throughout all growing phases. Optimizing costs to raise heifers improves profitability of dairy farms. Feed costs for heifers make up 50% of heifer costs. Required growth rates depend on the desired age at first calving and estimated mature body weight. Intensive milk feeding improves calf growth and subsequent milk production. Prepubertal heifers should be fed for adequate gains to calve between 22 and 24 months of age. Controlling gains in pregnant heifers to limit fat deposition is possible using limit-feeding of a higher concentrate diet or using high-fiber forages to reduce diet energy. PMID:27161393

    2014-04-01

    Presented here is an overview of the pathway from early nutrient deficiency to long-term brain function, cognition, and productivity, focusing on research from low- and middle-income countries. Animal models have demonstrated the importance of adequate nutrition for the neurodevelopmental processes that occur rapidly during pregnancy and infancy, such as neuron proliferation and myelination. However, several factors influence whether nutrient deficiencies during this period cause permanent cognitive deficits in human populations, including the child's interaction with the environment, the timing and degree of nutrient deficiency, and the possibility of recovery. These factors should be taken into account in the design and interpretation of future research. Certain types of nutritional deficiency clearly impair brain development, including severe acute malnutrition, chronic undernutrition, iron deficiency, and iodine deficiency. While strategies such as salt iodization and micronutrient powders have been shown to improve these conditions, direct evidence of their impact on brain development is scarce. Other strategies also require further research, including supplementation with iron and other micronutrients, essential fatty acids, and fortified food supplements during pregnancy and infancy.

    2011-01-01

    A growing body of evidence highlights the importance of a mother’s nutrition from preconception through lactation in programming the emerging organ systems and homeostatic pathways of her offspring. The developing immune system may be particularly vulnerable. Indeed, examples of nutrition-mediated immune programming can be found in the literature on intra-uterine growth retardation, maternal micronutrient deficiencies, and infant feeding. Current models of immune ontogeny depict a “layered” expansion of increasingly complex defenses, which may be permanently altered by maternal malnutrition. One programming mechanism involves activation of the maternal hypothalamic-pituitary-adrenal axis in response to nutritional stress. Fetal or neonatal exposure to elevated stress hormones is linked in animal studies to permanent changes in neuroendocrine-immune interactions, with diverse manifestations such as an attenuated inflammatory response or reduced resistance to tumor colonization. Maternal malnutrition may also have a direct influence, as evidenced by nutrient-driven epigenetic changes to developing T regulatory cells and subsequent risk of allergy or asthma. A 3rd programming pathway involves placental or breast milk transfer of maternal immune factors with immunomodulatory functions (e.g. cytokines). Maternal malnutrition can directly affect transfer mechanisms or influence the quality or quantity of transferred factors. The public health implications of nutrition-mediated immune programming are of particular importance in the developing world, where prevalent maternal undernutrition is coupled with persistent infectious challenges. However, early alterations to the immune system, resulting from either nutritional deficiencies or excesses, have broad relevance for immune-mediated diseases, such as asthma, and chronic inflammatory conditions like cardiovascular disease.

    The challenge of modern nutrition and health research is to identify food-based strategies promoting life-long optimal health and well-being. This research is complex because it exploits a multitude of bioactive compounds acting on an extensive network of interacting processes. Whereas nutrition research can profit enormously from the revolution in 'omics' technologies, it has discipline-specific requirements for analytical and bioinformatic procedures. In addition to measurements of the parameters of interest (measures of health), extensive description of the subjects of study and foods or diets consumed is central for describing the nutritional phenotype. We propose and pursue an infrastructural activity of constructing the "Nutritional Phenotype database" (dbNP). When fully developed, dbNP will be a research and collaboration tool and a publicly available data and knowledge repository. Creation and implementation of the dbNP will maximize benefits to the research community by enabling integration and interrogation of data from multiple studies, from different research groups, different countries and different-omics levels. The dbNP is designed to facilitate storage of biologically relevant, pre-processed-omics data, as well as study descriptive and study participant phenotype data. It is also important to enable the combination of this information at different levels (e.g. to facilitate linkage of data describing participant phenotype, genotype and food intake with information on study design and-omics measurements, and to combine all of this with existing knowledge). The biological information stored in the database (i.e. genetics, transcriptomics, proteomics, biomarkers, metabolomics, functional assays, food intake and food composition) is tailored to nutrition research and embedded in an environment of standard procedures and protocols, annotations, modular data-basing, networking and integrated bioinformatics.

    Aims: To assess the effect of maternal diet during pregnancy on the risk of delivering a baby who is small for gestational age (SGA). Methods: Case-control study of 844 cases (SGA) and 870 controls (appropriate size for gestational age (AGA)). Only term (37+ completed weeks of gestation) infants were included. Retrospective food frequency questionnaires were completed at birth on the diet at the time of conception and in the last month of pregnancy. Results: At the time of conception, mothers of AGA infants ate significantly more servings of carbohydrate rich food and fruit, and were more likely to have taken folate and vitamin supplements than mothers of SGA infants. There was some evidence that mothers of AGA infants also ate more servings of dairy products, meat, and fish (0.05 < p < 0.1). However, after adjustment for maternal ethnicity, smoking, height, weight, hypertension, and occupation, fish intake (p  =  0.04), carbohydrate-rich foods (p  =  0.04), and folate supplementation (p  =  0.02) were associated with a reduced risk of SGA. In the last month of pregnancy, only iron supplementation was associated with a reduced risk of SGA (p  =  0.05) after adjustment for potential confounders. Conclusions: This study suggests that small variations in maternal diets within the normal range during pregnancy in developed countries are associated with differences in birth weight.

    Recent epidemiological studies indicate a strong link between intrauterine under-nutrition and propensity of such offspring for developing obesity and metabolic syndrome in later life. Garg et al investigated the mechanistic basis of this phenomenon and its potential reversibility in rats. The authors found that rats experiencing gestational under-nutrition but fed normally after birth (IUGR) gained body mass with excessive subcutaneous and visceral fat. The IUGR rats were also metabolically inflexible since they showed similar rates of energy expenditure and O(2) consumption in the fed and fasted states. However, if such pups were food-restricted during lactation (PNGR), their metabolic profiles resembled those of control and IPGR (subject to food restriction during pre- and postnatal periods) rats. Thus, postnatal caloric restriction superimposed on intrauterine under nutrition significantly improved insulin sensitivity and adiposity of rats that would otherwise develop metabolic inflexibility and visceral obesity. The observations of Garg et al, have serious implications in term of the design of the future experimental studies as well as their clinical translation in humans. PMID:23193434

    Vinasse is a residue that originates from the distillation of fuel alcohol. However, it contains a relative amount of nutrients. The aim of this work was to develop a nutritive solution using vinasse and to compare it with a commercial solution for the cultivation of lettuce, watercress and rocket. Vinasse obtained from juice must was decanted and filtered, followed by chemical analyses of the nutrients. A nutritive solution composed of 10% vinasse supplemented with nutrients was in agreement with the results of the chemical analyses (a similar amount of Furlani's solution). Experiments were then performed in an NFT (Nutrient film technique) system. The treatments used the vinasse solution and a commercial solution constituted from a Yara Fertilizantes(®) product. The height of the aerial part and the number of leaves of the crops were evaluated at 7, 14, 21, 28, 35 and 42 days. In most crops, the results were very similar. The vinasse solution promoted a larger number of leaves in lettuce and the highest aerial part in watercress. For the rocket, there were no significant differences between the two solutions. In conclusion, a nutritive solution was developed using vinasse, and this solution provided suitable growth, which was higher in some cases, for the crops studied herein. This study shows the great potential of this technology as a rational alternative to vinasse disposal. PMID:23201600

The vinasse solution promoted a larger number of leaves in lettuce and the highest aerial part in watercress. For the rocket, there were no significant differences between the two solutions. In conclusion, a nutritive solution was developed using vinasse, and this solution provided suitable growth, which was higher in some cases, for the crops studied herein. This study shows the great potential of this technology as a rational alternative to vinasse disposal.

    1993-12-01

    This paper describes an investigation of concepts that various groups hold about food and nutrition. Groups investigated were students in Years 4 and 8, university students in a BEd (primary) program and parents of the Year 4 students. It was found that for many important concepts relating to food selection, the basic ideas of each group were surprisingly consistent, despite the influence of formal education. In particular, misconception about energy and its role in nutrition and particular food groups was an important finding. Implications for school and community education are drawn from the results.

    Myopia is the major cause for hypopsia of primary and middle school students. The height, weight and vision of 3,884 students were measured. It is concluded from their statistical analysis that vision and weight are positively interrelated whereas there is no interrelation found between vision and height. It is also pointed out that one of the key factors affecting vision is weight, which will be affected by irrational food structure, food preference and hypotrophy. The heavy study load of primary and middle school students is also one of the numerous causes for the increasing incidence of myopia. PMID:7843393

    Sustainable development, a foundation of the post-2015 global agenda, depends on healthy and productive citizens. The origins of adult health begin early in life, stemming from genetic-environmental interactions that include adequate nutrition and opportunities for responsive learning. Inequities associated with inadequate nutrition and early learning opportunities can undermine children's health and development, thereby compromising their productivity and societal contributions. Transactional theory serves as a useful framework for examining the associations that link early child development and nutrition because it emphasizes the interplay that occurs between children and the environment, mediated through caregiver interactions. Although single interventions targeting early child development or nutrition can be effective, there is limited evidence on the development, implementation, evaluation, and scaling up of integrated interventions. This manuscript introduces a special edition of papers on six topics central to integrated child development/nutrition interventions: (1) review of integrated interventions; (2) methods and topics in designing integrated interventions; (3) economic considerations related to integrated interventions; (4) capacity-building considerations; (5) examples of integrated interventions; and (6) policy implications of integrated interventions. Ensuring the health and development of infants and young children through integrated child development/nutrition interventions promotes equity, a critical component of sustainable development.

    SUMMARY Information on the status of long chain polyunsaturated fatty acids (LC-PUFA) in pregnancy and breast milk in very high fish eating populations is limited. The aim of this study was to examine dietary intake and changes in fatty acid status in a population of pregnant women in the Republic of Seychelles. Serum docosahexaenoic acid (DHA) decreased significantly between 28 weeks gestation and delivery (n=196). DHA status did not correlate significantly with length of gestation and was not associated with self reported fish intake which was high at 527 g/wk. In breast milk, the ratio of DHA to arachidonic acid (AA) was consistent with those observed in other high fish eating populations. Overall the data suggest that high exposure to LCPUFAs from habitual fish consumption does not prevent the documented decrease in LCPUFA status in pregnancy that occurs as a result of fetal accretion in the third trimester of pregnancy.

    New York State established a Nutrition Surveillance Program (NSP) in 1984. Precedents for the program included the Pediatric Nutrition Surveillance System of the Public Health Service's Centers for Disease Control and Prevention and periodic food and nutrition surveys conducted by the National Center for Health Statistics and the Human Nutrition Information Service, Department of Agriculture. The first phase of NSP was connected to a new program, the Supplemental Nutrition Assistance Program (SNAP), which established support for more than 1,000 emergency food programs across the State. SNAP also expanded the home delivered meal program for the frail elderly and the Special Supplemental Food Program for Women, Infants, and Children. NSP provided information on the extent of unmet nutrition needs that was used to establish funding requests and provided data describing the characteristics of SNAP participants that were used in developing new SNAP program components. The second phase of NSP began in 1988. It identified populations that were thought to be at nutrition risk and compiled information about the extent of unmet need, the characteristics of the population, and the status of current nutrition programs to meet the needs. As a result of this review, NSP added a nutrition component to the Dental Survey of School Children; conducted a dietary survey; developed an inventory of information sources in all State agencies; and established an annual work plan using department of health objectives. The third phase of NSP is the policy and planning phase, monitoring the Year 2000 Objectives and the Five-Year Plan of the New York State Food and Nutrition Policy Council. PMID:8464981

    The environment, defined broadly by all that is external to the individual, conditions the phenotype during development, particularly the susceptibility to develop non-communicable diseases. This notion, called Developmental Origins of Health and Disease (DOHaD), is based on numerous epidemiological studies as well as animal models. Thus, parental nutrition and obesity can predispose the offspring to develop metabolic and cardiovascular diseases in adulthood. The known underlying mechanisms include an altered development of tissues that adapt to maternal metabolic condition, and a placental dysfunction, which in turn impacts fetal growth and development. Epigenetic mechanisms modulate gene expression without affecting the DNA sequence itself. The main epigenetic marks are DNA methylation and histone post-translational modifications. These marks are erased and set-up during gametogenesis and development in order to ensure cellular identity. Therefore, they can lead to a memorisation of early environment and induce long-term alteration of cell and tissue functions, which will condition the susceptibility to non-communicable diseases. The placenta is a programming agent of adult disease. The environment, such as smoking or psychosocial stress, is able to modify epigenetic processes in placenta, such as small RNA expression and DNA methylation. We showed that placenta is sensitive to maternal obesity and maternal nutrition, in terms of histology, transcription and epigenetic marks. A clear sexual dimorphism is remarkable in the placental response to maternal environment. In adulthood, the phenotype is also different between males and females. Epigenetic mechanisms could underlie this differential response of males and females to the same environment. The DOHaD can no longer be ignored in Biology of Reproduction.

    Multifaceted community interventions directed at improving food environments are emerging, but their impact on dietary change and obesity prevalence has not been documented adequately. The Healthy Communities Study (HCS) is seeking to identify characteristics and combinations of programs and policies that are associated with children’s diets and obesity-related outcomes in various types of communities across the U.S. The purpose of this paper is to describe the methods used in 2013–2015 in the HCS to assess dietary intake, school nutrition environments, and other nutrition-related behaviors. The conceptual framework of the HCS is based on the socioecological model and behaviors shown in previous studies to be related to obesity in children-guided selection of domains. Nine domains were identified as essential measures of nutrition in the HCS: (1) intake of selected foods and beverages; (2) food patterns and behaviors; (3) social support; (4) home environment; (5) school environment; (6) community environment; (7) breastfeeding history; (8) household food insecurity; and (9) dieting behaviors and body image. Children’s dietary intake was assessed using a dietary screener and up to two automated 24-hour recalls. Dietary-related behaviors were assessed by a survey administered to the parent, child, or both, depending on child age. School nutrition measures were obtained from a combination of school staff surveys and researcher observations. Information from these measures is expected to contribute to a better understanding of “what is working” to improve the dietary behaviors that are likely to prevent obesity and improve health in children.

    Maternal nutrition during pregnancy and lactation influences the offspring's health in the long-term. Indeed, human epidemiological studies and animal model experiments suggest that either an excess or a deficit in maternal nutrition influence offspring development and susceptibility to metabolic disorders. Different epigenetic mechanisms may explain in part the way by which dietary factors in early critical developmental steps might be able to affect the susceptibility to develop metabolic diseases in adulthood. microRNAs are versatile regulators of gene expression and play a major role during tissue homeostasis and disease. Dietary factors have also been shown to modify microRNA expression. However, the role of microRNAs in fetal programming remains largely unstudied. This review evaluates in vivo studies conducted to analyze the effect of maternal diet on the modulation of the microRNA expression in the offspring and their influence to develop metabolic and cardiovascular disease in later life. In overall, the available evidence suggests that nutritional status during pregnancy influence offspring susceptibility to the development of cardiometabolic risk factors, partly through microRNA action. Thus, therapeutic modulation of microRNAs can open up new strategies to combat - later in life - the effects of nutritional insult during critical points of development.

    2016-01-01

    Background The population of Portugal is aging. The lack of data on older adults’ nutritional status and the lack of nutrition knowledge amongst health professionals, caregivers, and older adults themselves, remains a challenge. Objective The Nutrition UP 65 study aims to reduce nutritional inequalities in the older Portuguese adult population and improve knowledge regarding older Portuguese adults’ nutritional status, specifically relating to undernutrition, obesity, sarcopenia, frailty, hydration, sodium, and vitamin D statuses. Methods A representative sample of older Portuguese adults was selected. Sociodemographic, lifestyle, anthropometric, functional, and clinical data were collected. Sodium excretion, hydration, and vitamin D statuses were assessed. Results Data collection (n=1500) took place between December, 2015 and June, 2016. Results will be disseminated in national and international scientific journals, and via Portuguese media. Conclusions Nutrition UP 65 results will provide evidence for the design and implementation of effective preventive public health strategies regarding the elderly. These insights may represent relevant health gains and costs savings. PMID:27628097

    While most Third World countries, particularly in Africa and Latin America, have experienced a deterioration in child welfare as a result of the severe economic downturn in the 1980s, Southeast Asia in general managed to sustain improvements in the situation of its children because it has maintained satisfactory rates of economic growth. However, there were exceptions within Southeast Asia. The Philippines, Vietnam, Dem. Kampuchea and Laos had unsatisfactory growth rates and, consequently, unsustained nutritional gains from the 1970s through the 1980s. Economic factors exerted a big impact on the Philippine nutrition situation, particularly on the dietary status of the households and the nutritional status of children. As a result of the economic dislocation occurring in the country, the nutritional gains of 1978-82 were not maintained in succeeding years. Unlike the case of Thailand, it has been estimated that the solution to nutritional problems in the Philippines is far from being achieved in the immediate future (Villavieja et al. 1989). On the other hand, the nutrition improvements in Thailand have been as remarkable as the economic growth over the last decade. Long-term investments in health, nutrition and other social services in Thailand (as well as in Indonesia) have paid off according to the assessment by the United Nations (1990). It appears, therefore, that the nutrition situation in developing countries is highly dependent on the economic situation, globally and nationally (Cornia et al. 1987), as well as on investment in social services. Adjustment policies should, therefore, consider their implications on distribution and poverty in order that they could positively contribute to the improvement of the nutrition of the people.

    The objectives of this study were 1) to examine the interactive influence of a compensatory nutrition regimen and lasalocid supplementation on dairy heifer growth performance and 2) to document the extent to which compensatory growth sustains lactation potential over the first two lactation cycles. Twelve Holstein heifers, weighing an average of 160 kg (about 6 mo of age) were randomly assigned to treatments arranged in a 2 x 2 factorial design. Treatment variables were two dietary regimens (control and stair-step compensatory nutrition) and two levels of lasalocid (0 and 200 mg/d). The control heifers were fed a diet containing 12% crude protein (CP) and 2.35 Mcal of metabolizable energy (ME) per kilogram of dry matter. The stair-step compensatory nutrition heifers were subjected to a phased nutrition regimen and reared according to an alternating 3-2-4-3-4-2-mo schedule. The first stair-step (prepubertal phase) consisted of energy restriction [17% CP and 2.35 Mcal/kg of ME] for 3 mo followed by realimentation (12% CP and 3.05 Mcal/kg of ME) for 2 mo. The second step (puberty and breeding) consisted of energy restriction for 4 mo followed by realimentation for 3 mo. The third step (gestation period) was energy restriction for 4 mo concluding with realimentation for 2 mo. Dry matter intake of heifers during the restriction phase was limited to 70% of the control intake. Heifers were given ad libitum access to a high energy density diet during realimentation to allow compensatory development. Stair-step heifers supplemented with lasalocid had the highest efficiency of growth (body weight gain/dry matter intake), suggesting synergistic metabolism of lasalocid with compensatory growth action. Compensatory growth induced during the last trimester enhanced metabolic status by increasing circulating insulin and decreasing triglyceride levels. Heifers on the stair-step regimen had a significant increase in milk yield during the first (21%) and second (15%) lactation

    We examined the effect of nutritional supplements (modified Age Related Eye Disease Study (AREDS)-II formulation containing vitamins, minerals, lutein, resveratrol, and omega-3 fatty acids) on choroidal neovascularization (CNV). Supplements were administered alone and combined with intravitreal anti-VEGF in an early-CNV (diode laser-induced) murine model. Sixty mice were evenly divided into group V (oral vehicle, intravitreal saline), group S (oral supplement, intravitreal saline), group V + aVEGF (oral vehicle, intravitreal anti-VEGF), and group S + aVEGF (oral supplement, intravitreal anti-VEGF). Vehicle and nutritional supplements were administered daily for 38 days beginning 10 days before laser. Intravitreal injections were administered 48 h after laser. Fluorescein angiography (FA) and flat-mount CD31 staining evaluated leakage and CNV lesion area. Expression of VEGF, MMP-2 and MMP-9 activity, and NLRP3 were evaluated with RT-PCR, zymography, and western-blot. Leakage, CNV size, VEGF gene and protein expression were lower in groups V + aVEGF, S + aVEGF, and S than in V (all p < 0.05). Additionally, MMP-9 gene expression differed between groups S + aVEGF and V (p < 0.05) and MMP-9 activity was lower in S + aVEGF than in V and S (both p < 0.01). Levels of MMP-2 and NLRP3 were not significantly different between groups. Nutritional supplements either alone or combined with anti-VEGF may mitigate CNV development and inhibit retinal disease involving VEGF overexpression and CNV. PMID:26153682

  1. Nutrition influences bone development from infancy through toddler years.

    PubMed

    Specker, Bonny

    2004-03-01

    During the last decade a greater appreciation has developed for determining factors that influence bone accretion in healthy children. Nutritional factors that may contribute to bone accretion in infants and toddlers include maternal nutritional status during pregnancy, type of infant feeding, calcium and phosphorus content of infant formula, introduction of weaning foods, and diet during the toddler and preschool years. Maternal vitamin D deficiency during pregnancy is associated with disturbances in neonatal calcium homeostasis, and maternal calcium deficiency leads to reduced neonatal bone mineral content (BMC). Preterm infants are at increased risk of osteopenia, and, although the use of high mineral formula has reduced the risk of osteopenia in these infants, it has not eliminated it. The reason for the long-term bone deficiency among preterm infants is not clear, although lower physical activity levels have been suggested as a potential cause. Studies find that human milk-fed infants have lower bone accretion than do formula-fed infants; that the greater the mineral content of formula, the greater the bone accretion; and that the inclusion of palm olein oil in infant formula may reduce bone mineral accretion. Bone accretion is not influenced by the timing of the introduction of weaning foods, despite higher serum parathyroid hormone (PTH) concentrations among infants who receive solids earlier. There is evidence of calcium intake-by-gene and calcium intake-by-physical activity interactions among toddlers and young children. The long-term effects of these early nutritional influences on later bone health are unknown. PMID:14988469

    2013-09-01

    Nutrition and growth are still a major challenge in neonatal intensive care. Many studies have demonstrated that premature infants frequently develop severe cumulative nutritional deficit during the first weeks of life. This malnutrition is the primary etiology of postnatal growth restriction, which is still universally described in very premature infants. Furthermore, both postnatal nutritional deficit and postnatal growth restriction have been associated with adverse long-term outcome in adulthood. Due to their immaturity, premature infants are frequently not fed by the enteral route. Therefore, parenteral nutrition remains an essential therapy in neonatology. Most recent recommendations suggest starting parenteral nutrition as soon as possible after birth with a minimum of 40 kcal/kg/day with around 2-3g/kg/day of amino acids and 1g/kg/day of lipids. Afterwards, intake should increase rapidly during the first week of life, up to 90-120 kcal/kg/day with around 3.5 g/kg/day amino acids and 3g/kg/day of lipids. There is great heterogeneity in parenteral nutrition practices among neonatal units, with frequent discrepancies. This article discusses the principal theoretical aspects of parenteral nutrition in premature infants, the guidelines, and the opportunity to optimize nutritional support routinely, especially in very premature infants.

    The aims of this study were (1) to carry out a nutritional assessment of selected Irish athletes and (2) to provide individual results and specific advice to each athlete on how to achieve an optimum diet. Dietary intakes were measured by a three-day weighed dietary record technique designed to evaluate each athlete's usual eating habits. The results were evaluated against a set of dietary standards in order to determine adequacy. Nutritional status was also assessed in a limited form by selected anthropometric and biochemical measurements. A total of 148 subjects took part in the assessment which began in May, 1979 and continued until April, 1980. The sports involved included: canoeing, cycling, rowing, swimming, hockey, squash and track and field events. The results indicated a range of sub-optimal dietary patterns relating in particular to abnormal intakes of folate, iron, pyridoxine and calcium. The significance and applications of these findings are discussed. ImagesFig. 1Fig. 2Fig. 3Fig. 4Fig. 5Fig. 6Fig. 7Fig. 8 PMID:7023594

In 1998 the National Academy of Sciences, USA, issued a report identifying choline as a required nutrient for humans and recommended daily intake amounts. In ongoing studies we are finding that men have a higher requirement than do postmenopausal women, who in turn need more than premenopausal women. Pregnancy and lactation are periods when maternal reserves of choline are depleted. At the same time, the availability of choline for normal development of brain is critical. When rat pups received choline supplements (in utero or during the second week of life), their brain function is changed, resulting in lifelong memory enhancement. This change in memory function appears to be due to changes in the development of the memory center (hippocampus) in brain. These changes are so important that investigators can pick out the groups of animals whose mothers had extra choline even when these animals are elderly. Thus, memory function in the aged is, in part, determined by what mother ate. Foods highest in total choline concentrations per 100 g were beef liver (418 mg), chicken liver (290 mg), and eggs (251 mg). We suggest that choline-rich foods are an important component of the diet and that especially during pregnancy it would be prudent to include them as part of a healthy diet. PMID:15640516

  6. Impact of nutritional programming on the growth, health, and sexual development of bull calves.

    The growth, health, and reproductive performance of bull calves are important prerequisites for a successful cattle breeding program. Therefore, several attempts have been made to improve these parameters via nutritional programming. Although an increase in energy uptake during the postweaning period (7-8 mo of age) of the calves leads to a faster growing rate, it has no positive effects on sexual development. In contrast, a high-nutrition diet during the prepubertal period (8-20 wk of age) reduced the age at puberty of the bulls and increased the size and/or weight of the testis and the epididymal sperm reserves. This faster sexual development is associated with an increased transient LH peak, which seems to be mediated by an increase in serum IGF-I concentrations. However, the exact mechanisms responsible for the interaction between nutrition and the subsequent development of the calves are not clear. The sexual development of bull calves depends not only on the nutrition of the calves after birth but also on the feed intake of their mothers during pregnancy. In contrast to the effects of the feed intake of the bull calves, a high-nutrition diet fed to the mother during the first trimester has negative effects on the reproductive performance of their offspring. In conclusion, it has been clearly demonstrated that growth, health, and reproductive performance can be improved by nutritional programming, but further studies are necessary to obtain a better understanding about the mechanisms responsible for this phenomenon.

  12. Nutritional and engineering aspects of microbial process development.

    Today we use many drugs produced by microorganisms. However, when these drugs were discovered it was found that the yields were low and a substantial effort had to be put in to develop commercially viable processes. A key part of this endeavor was the studies of the nutritional and the engineering parameters. In this chapter, the basic principles of optimizing the nutritional and engineering aspect of the production process are described with appropriate examples. It was found that two critical components of nutritional medium, carbon and nitrogen source regulated the synthesis of the compounds of interest. Rapidly utilizable carbon source such as glucose supported the growth but led to catabolite repression and alternative carbon sources or methods of addition had to be devised. Inorganic nitrogen sources led to undesirable changes in pH of the medium. Organic nitrogen sources could influence the yields positively or negatively and had to be chosen carefully. Essential nutrients like phosphates often inhibited the synthesis and its concentration had to be maintained below the inhibitory levels. On many occasions, trace nutrients like metal ions and vitamins were found to be critical for good production. Temperature and pH were important environmental variables and their optimum values had to be determined. The media were designed and optimized initially with 'one variable at a time' approach and later with experimental design based on statistics. The latter approach is preferred because it is economical, considers interactions between medium components and allows rapid optimization of the process. The engineering aspects like aeration, agitation, medium sterilization, heat transfer, process monitoring and control, become critical as the process is scaled-up to the production size. Aeration and agitation are probably the most important variables. In many processes dissolved oxygen concentration had to be maintained above a critical value to obtain the best yields

  13. Maternal nutrition during pregnancy as it affects infant growth, development and health.

    PubMed

    Norton, R

    1994-01-01

    Strong epidemiological evidence exists of an association between maternal nutritional status, during and before pregnancy, and birthweight and intrauterine growth retardation (IUGR). Trials of nutritional supplementation during pregnancy have, however, found only a modest effect of supplementation on birthweight, even in undernourished women. One study even found no long-term benefit to children in terms of growth or neurocognitive development. Since it is not clear whether the supplementation trials were conducted at the right time during pregnancy, future supplementation during pregnancy should probably be targeted at nutritionally disadvantaged populations during all three trimesters of pregnancy. Distinguishing between IUGR and prematurity, and between stunted and wasted IUGR infants would be helpful in future trials. More research is also needed on the effect of maternal nutrition during pregnancy on preterm delivery, and during consecutive pregnancies and prior to pregnancy.

    The National Institute of Standards and Technology (NIST) has established a Dietary Supplement Laboratory Quality Assurance Program (DSQAP) in collaboration with the National Institutes of Health Office of Dietary Supplements (NIH-ODS). The DSQAP invites laboratories twice annually to participate in interlaboratory studies where participants elect to measure concentrations of nutritional and/or toxic elements as well as active and/or marker compounds. One of these studies was designed to determine the effects of material granularity and sample processing techniques on measurement variability (precision) as well as to provide participating laboratories information on their performance relative to the NIST assigned values (bias) and to the other participants (concordance). Participants were asked to determine the mass fractions of Ca, Fe, and Zn, in mg/kg, in six breakfast cereal samples. Cereal samples consisted of three ground materials (homogenized wheat, wheat, and rice), two flake materials (wheat and rice) and a partially crushed material (a wheat/rice mixture). In general, approximately 25% of the laboratories processed and analyzed the suite of six cereal materials with adequate to exemplary measurement precision. Over half of the laboratories (60%) experienced measurement issues related to only a particular type of cereal matrix or for only a single element. A small number (15%) of laboratories experienced significant sample processing or measurement problems. Future studies planned by the DSQAP may be designed to use commercial products to aid laboratories with their sampling and analytical techniques. PMID:23380950

    PURPOSE . To describe the collaborative process between a grocery retailer and a panel of nutrition experts used to develop a nutrition guidance system (Guiding Stars) that evaluates the nutrient profile of all edible products in the supermarket, and to report the results of the food and beverage ratings. DESIGN . A collaboration between a private retailer and members of the scientific community that led to the development of a scoring algorithm used to evaluate the nutritional quality of foods and beverages. SETTING/SUBJECTS . Northeast supermarkets (n  =  160). MEASURES . Food and beverage nutrition ratings and distribution of stars across different grocery categories. ANALYSIS . Descriptive statistics for rating distributions were computed. T-tests were conducted to assess differences in mean nutrient values between foods with zero versus three stars or a dichotomized variable representing all foods with one to three stars. RESULTS . All edible grocery items (n  =  27,466) were evaluated, with 23.6% earning at least one star. Items receiving at least one star had lower mean levels of sodium, saturated fat, and sugars and higher amounts of fiber than products not earning stars. CONCLUSION . The Guiding Stars system rates edible products without regard to brand or manufacturer, and provides consumers with a simple tool to quickly identify more nutritious choices while shopping. The low percentage of products qualifying for stars reflects poorly on the food choices available to Americans. PMID:22040397

    Dyslipidemia has significantly contributed to the increase of death and morbidity rates related to cardiovascular diseases. Clinical nutrition service provided by dietitians has been reported to have a positive effect on relief of medical symptoms or reducing the further medical costs. However, there is a lack of researches to identify key competencies and job standard for clinical dietitians to care patients with dyslipidemia. Therefore, the purpose of this study was to analyze the job components of clinical dietitian and develop the standard for professional practice to provide effective nutrition management for dyslipidemia patients. The current status of clinical nutrition therapy for dyslipidemia patients in hospitals with 300 or more beds was studied. After duty tasks and task elements of nutrition care process for dyslipidemia clinical dietitians were developed by developing a curriculum (DACUM) analysis method. The developed job standards were pretested in order to evaluate job performance, difficulty, and job standards. As a result, the job standard included four jobs, 18 tasks, and 53 task elements, and specific job description includes 73 basic services and 26 recommended services. When clinical dietitians managing dyslipidemia patients performed their practice according to this job standard for 30 patients the job performance rate was 68.3%. Therefore, the job standards of clinical dietitians for clinical nutrition service for dyslipidemia patients proposed in this study can be effectively used by hospitals. PMID:25954728

    Increasing evidence from lifetime experimental studies in animals and observational and experimental studies in human subjects suggests that pre- and postnatal nutrition programme long-term health. However, key unanswered questions remain on the extent of early-life programming in contemporary European populations, relevant nutritional exposures, critical time periods, mechanisms and the effectiveness of interventions to prevent or reverse programming effects. The EARly Nutrition programming - long-term Efficacy and Safety Trials and integrated epidemiological, genetic, animal, consumer and economic research (EARNEST) consortium brings together a multi-disciplinary team of scientists from European research institutions in an integrated programme of work that includes experimental studies in human subjects, modern prospective observational studies and mechanistic animal work including physiological studies, cell-culture models and molecular techniques. Theme 1 tests early nutritional programming of disease in human subjects, measuring disease markers in childhood and early adulthood in nineteen randomised controlled trials of nutritional interventions in pregnancy and infancy. Theme 2 examines associations between early nutrition and later outcomes in large modern European population-based prospective studies, with detailed measures of diet in pregnancy and early life. Theme 3 uses animal, cellular and molecular techniques to study lifetime effects of early nutrition. Biomedical studies are complemented by studies of the social and economic importance of programming (themes 4 and 5), and themes encouraging integration, communication, training and wealth creation. The project aims to: help formulate policies on the composition and testing of infant foods; improve the nutritional value of infant formulas; identify interventions to prevent and reverse adverse early nutritional programming. In addition, it has the potential to develop new products through industrial

    In order to improve the taste, flavor and nutritional quality of chickpea (Cicer arietinum), various processing conditions were studied. The decorticated samples were processed under various conditions, either by presoaking or non-soaking in water or sodium carbonate solution. The proteins were also isolated from water or carbonate-presoaked chickpea and subjected to various processing. Carbonate-presoaked samples gave slightly lower protein and ash values. No major changes in other constituents were observed. Subjective analysis of the intensity of characteristic chickpea flavor in processed samples was carried out, indicating some improvement in the carbonate-presoaked samples. Carbonate-treated samples exhibited a lighter color. The carbonate presoaking procedure had no adverse effect on the availability of lysine and nitrogen solubility index (NSI), as compared to the water-presoaking procedure. The time required to inactivate trypsin inhibitors in carbonate-presoaked chickpea at boiling temperature, was half that required in the case of water-presoaked ones. Under the conditions used in treating chickpea with sodium carbonate, no beneficial effect was observed in reducing the tannin content. No significant differences were observed in net protein ratio (NPR) among the various processed chickpea samples, even though in some cases isolated protein gave significantly lower NPR values. Digestibility values were higher for isolated protein than for whole chickpea samples.

    In Italy, like in most parts of the world, 30% of children and almost 50% of adults are overweight. This condition is one of the causes of non-communicable diseases responsible for over two thirds of DALYs, deaths and costs for healthcare. Current surveys confirm that overweight and obesity are associated with food habits which have changed, in Italy, in the last fifty years. Fewer and fewer people have been following a Mediterranean diet, which is considered an effective diet for the prevention of many diseases. The consumption of fruit, vegetables, legumes, whole cereals, and EVO oil has decreased, while the consumption of food with high energetic density and rich in sugar, salt, and added fat has increased, especially when eating out. Schools and workplaces are the best places to promote healthy food habits and an active lifestyle. The aim is to involve families (including low-income families), educators, and catering services. This type of intervention is not new to the National Health System and has already led to improvements: however, it is still possible to improve the use of resources and coordination between social, educational, and health services bringing the community to become its own health promoter. Health operators have to be more aware of overweight as a health threat. The National Health Plan represents a commitment for Italy, the country hosting EXPO 2015, to fulfill the targets of the «Action Plan European Strategy for the Prevention and Control of Non-communicable Diseases 2012-2016» entrusting the Departments of Prevention with the interventions and development of a network of stakeholders.

    The development of nutrition and health guidelines and policies requires reliable scientific information. Unfortunately, theoretical considerations and empirical evidence indicate that a large percentage of science-based claims rely on studies that fail to replicate. The session "Strategies to Optimize the Impact of Nutrition Surveys and Epidemiological Studies" focused on the elements of design, interpretation, and communication of nutritional surveys and epidemiological studies to enhance and encourage the production of reliable, objective evidence for use in developing dietary guidance for the public. The speakers called for more transparency of research, raw data, consistent data-staging techniques, and improved data analysis. New approaches to collecting data are urgently needed to increase the credibility and utility of findings from nutrition epidemiological studies. Such studies are critical for furthering our knowledge and understanding of the effects of diet on health. PMID:24038252

    Abstract. Malnutrition is one of the most prevalent problems in older people, but there is little information about the nutritional status of the older women in China. Therefore, this study was conducted to investigate the nutritional status and clinically correlated factors for malnutrition in older Han women in China. In total, 2,556 hospital- and community-based Han women aged 60 years or older were recruited between May 2007 and December 2014. All women completed comprehensive geriatric assessment, and the Mini Nutritional Assessment Short Form (MNA-SF) was used to assess the nutritional status. The clinically corre- lated factors for malnutrition were also analyzed, including social factors, health status, and dietary behavior. The average age of these women was 75.9 ± 9.4 years, and 63.8% women lived in urban areas. Of the total respondents, 344 and 716 women were classified as malnutrition and at risk of malnutrition, respectively. Five factors were independently and positively correlated with poor nutrition, including chronic obstructive pulmonary disease (COPD), gastrointestinal disease, depression, cognitive impairment, and comorbidity (≥ 2). Three factors were independently and negatively correlated with poor nutrition, including economic status, meat intake, and fish intake. The older Han women with these five health problems should be given more attention with regards to their nutritional status. Improving economic status, eating more meat and fish were recommended for preventing poor nutrition in older women.

YouTube videos (n=115) of children alone and interacting with parents in toy kitchen settings were analyzed using constant comparison analysis. Results revealed that in the videos of play nutritional behaviours, children showed influences of their real social environments, and that this medium enabled the observation of parent-child interactions in a more natural context without the researcher's presence. These findings encourage further research in the development and validity of alternative methods of data collection. PMID:20171252

    Background Weight loss in patients with Alzheimer's disease (AD) is a common clinical manifestation that may have clinical significance. Objectives To evaluate if there is a difference between nutrition education and oral nutritional supplementation on nutritional status in patients with AD. Methods A randomized, prospective 6-month study which enrolled 90 subjects with probable AD aged 65 years or older divided into 3 groups: Control Group (CG) [n = 27], Education Group (EG) [n = 25], which participated in an education program and Supplementation Group (SG) [n = 26], which received two daily servings of oral nutritional supplementation. Subjects were assessed for anthropometric data (weight, height, BMI, TSF, AC and AMC), biochemical data (total protein, albumin, and total lymphocyte count), CDR (Clinical Dementia Rating), MMSE (Mini-mental state examination), as well as dependence during meals. Results The SG showed a significant improvement in the following anthropometric measurements: weight (H calc = 22.12, p =< 0.001), BMI (H calc = 22.12, p =< 0.001), AC (H calc = 12.99, p =< 0.002), and AMC (H calc = 8.67, p =< 0.013) compared to the CG and EG. BMI of the EG was significantly greater compared to the CG. There were significant changes in total protein (H calc = 6.17, p =< 0.046), and total lymphocyte count in the SG compared to the other groups (H cal = 7.94, p = 0.019). Conclusion Oral nutritional supplementation is more effective compared to nutrition education in improving nutritional status. PMID:21943331

    To better understand the impact of undernutrition, nutritional risk, and nutritional treatment on the clinical outcomes of hospitalized cancer patients in China, the authors conducted a multicenter, cross-sectional study with 2248 cancer patients from 20 hospitals from January to June 2010. The authors defined 19.7% and 26.8% patients as undernourished at baseline and reassessment, respectively. Patients with gastrointestinal malignancies had a higher rate of undernutrition than other patients. The nutritional risk rate was 24.6% and 40.2% at baseline and reassessment, respectively. For patients with nutritional risk, the relative risk (RR) of adverse events (AEs) significantly increased with and without nutritional treatment. In comparison with the nonnutritional treatment subgroup, patients who received enteral nutrition (EN) or total parenteral nutrition (TPN) significantly reduced the RR of AE development. The RR of AEs for EN and TPN were 0.08 (95% CI: 0.01-0.62) and 0.56 (95% CI: 0.33-0.96), respectively. Separated nutrient infusion increased the risk of AEs. The authors concluded that undernutrition and nutritional risk are general problems that impact the outcomes of hospitalized cancer patients in China. Higher NRS2002 scores are related to AE risk but not weight loss. In nutritional treatment, EN and TPN can significantly reduce the risk of AEs.

    Docosahexanoic acid (C22:6, DHA) is a highly unsaturated omega-3 fatty acid that forms part of the central nervous and visual system structures. DHA is synthesized from its precursor, alfa-linolenic acid, that is also a omega-3 fatty acid and can be obtained from vegetable oils. Marine organisms, specially fish, are good nutritional sources of DHA and eicosapentanoic acid (EPA), another omega-3 fatty acid that has a role in vascular homeostasis. DHA increases membrane fluidity, improving neurogenesis, synaptogenesis and the activity of retinal photoreceptors. The fetus, specially during the last trimester of pregnancy, has high DHA requirements. It is provided by the mother, since fetal DHA synthesis is negligible in this stage of development. Breast feeding provides DHA to the child, but most replacement artificial formulas do not provide this fatty acid. At the present moment, many products for infant nutrition contain DHA.

  17. Developing suitable methods of nutritional status assessment: a continuous challenge.

    Reliable information about the nutritional status is essential to identify potential critical nutrients and the population groups at risk of deficiency, as well as to develop effective public health policies to counteract unfavorable nutrition patterns that contribute to morbidity and mortality. In this review, the important role of biomarkers in the assessment of nutritional status is outlined, major strengths and limitations of established and new biomarkers are described, and important criteria for biomarker selection and development are discussed. Indeed, biomarkers offer a more objective assessment tool than pure dietary approaches that suffer from inadequate data reporting in particular, although biomarkers are often only measured in subsamples because of the higher costs and proband burden they entail. However, biomarkers are subject to individual variability and influences from other factors besides the nutrient of interest. Rapid turnover or tight control of nutrient concentrations in blood (homeostasis) limits their sensitivity as biomarkers, as in the case of many trace elements. The existence of different forms of a micronutrient in the body adds additional complexity. Functional biomarkers, such as enzyme activities, mirror long-term status better but are subject to confounding factors, and some are influenced by several micronutrients, not specific for only 1, so using a combination of biomarkers is advisable. Additionally, the applicability of a biomarker also depends on the existence of adequate reference values and cutoff points for the target population. Therefore, a careful selection is warranted, especially when biomarkers are to be used in larger samples.

    The Millennium Development Goals (MDGs) have contributed to unprecedented reductions in poverty and improvement in the lives of millions of men, women, and children in low- and middle-income countries. Yet, hundreds of millions of children under 5 y of age are not reaching their developmental potential. This article reviews the scientific basis for early childhood nutrition and child development interventions, the impact of integrated interventions on children's linear growth and cognitive development, and implementation strategies for integrated nutrition and child development programs. Advances in brain science have documented that the origins of adult health and well-being are grounded in early childhood, from conception through age 24 mo (first 1000 d) and extending to age 5 y (second 1000 d). Young children with adequate nutrition, nurturant caregiving, and opportunities for early learning have the best chances of thriving. Evidence from adoption, experimental, and quasi-experimental studies has shown that stunting prevention is sensitive during the first 1000 d, and sensitivity to child development interventions extends through the second 1000 d. Cognitive development responds to interventions post–1000 d with effect sizes that are inversely associated with initial age and length of program exposure. Integrated interventions need governance structures that support integrated policies and programming, with attention to training, supervision, and monitoring. The MDGs have been replaced by the Sustainable Development Goals (SDGs), with targets for the next 15 y. Achievement of the SDGs depends on children receiving adequate nutrition, nurturant caregiving, and learning opportunities from conception through age 5. PMID:26875208

    The Supplemental Nutrition Assistance Program (SNAP) protects households from severe food insecurity or extreme poverty, buffers against certain adverse health effects, and exhibits a multiplier effect on the nation's economy. Nonetheless, SNAP remains contentious and benefit reductions are currently being debated. One new direction is to reconceptualize people-based SNAP allocations within place-based community development. Programs such as the federal Healthy Food Financing Initiative encourage retailer development in underserved neighborhoods, creating healthy options and opportunities to reinvest SNAP dollars locally. By exploring relationships between these programs, researchers and practitioners can better understand how to enhance their impact on individuals and neighborhoods.

    The double burden of childhood undernutrition and adult-onset adiposity in transitioning societies poses a significant public health challenge. The development of suboptimal lean body mass (LBM) could partly explain the link between these two forms of malnutrition. This review examines the evidence on both the role of nutrition in “developmental programming” of LBM and the nutritional influences that affect LBM throughout the life course. Studies from developing countries assessing the relationship of early nutrition with later LBM provide important insights. Overall, the evidence is consistent in suggesting a positive association of early nutritional status (indicated by birth weight and growth during first 2 years) with LBM in later life. Evidence on the impact of maternal nutritional supplementation during pregnancy on later LBM is inconsistent. In addition, the role of nutrients (protein, zinc, calcium, vitamin D) that can affect LBM throughout the life course is described. Promoting optimal intakes of these important nutrients throughout the life course is important for reducing childhood undernutrition as well as for improving the LBM of adults.

    During the last two decades, the public and private sectors have made substantial research progress internationally toward improving the nutritional value of a wide range of food and feed crops. Nevertheless, significant numbers of people still suffer from the effects of undernutrition. As newly developed crops with nutritionally improved traits come closer to being available to producers and consumers, scientifically sound and efficient processes are needed to assess the safety and nutritional quality of these crops. In 2004, a Task Force of international scientific experts, convened by the International Food Biotechnology Committee (IFBiC) of ILSI, published recommendations for the safety and nutritional assessment of foods and feeds nutritionally improved through modern biotechnology (J. Food Science, 2004, 69:CRH62-CRH68). The comparative safety assessment process is a basic principle in this publication and is the starting point, not the conclusion, of the analysis. Significant differences in composition are expected to be observed in the case of nutritionally enhanced crops and must be assessed on a case-by-case basis. The Golden Rice 2 case study will be presented as an example of a food crop nutritionally enhanced through the application of modern biotechnology (i.e., recombinant DNA techniques) to illustrate how the 2004 recommendations provide a robust paradigm for the safety assessment of "real world" examples of improved nutrition crops.

    The purpose of this study was to design, develop, and formatively evaluate a computer-based multi-media nutrition education program for adults based on the Dick and Carey model of instructional design. The 4 phases of the study included analysis, design, development, and evaluation. Seventy-two volunteers from the US Air Force, aged 18 to 50 years, participated in focus groups, an E-mail survey, or a dietitian survey to establish the program's instructional goal of applying the principles of the Food Guide Pyramid to daily food choices. Objectives, assessment instruments, content, examples, and practice questions with feedback were written in the design phase. Four modules of instruction--Familiarization with Food Groups, Serving Sizes, Modifying a Menu, and Vitamins and Minerals--were programmed using Hyper-studio. Eighteen subjects aged 22 to 40 years, with at least a high school education and an average knowledge of nutrition volunteered to participate in 1 of 2 formative evaluation phases. All subjects completed a pretest, 2 posttests, 3 embedded tests, and an attitude questionnaire to ascertain program weaknesses. One module was deleted after phase 1 because the material lacked relevance to subjects. In phase 2, only 4 of 15 subjects could identify serving sizes in module 2 and only 6 of 15 subjects could do the same on posttest 1. Back buttons and review screens were added to modules 2 and 3 to facilitate identification of serving sizes. We conclude that dietetics professionals should use systematic models of instructional design, such as the Dick and Carey model, to design effective nutrition education programs for the public.

    Successful integration of nutrition interventions into large-scale development programmes from nutrition-relevant sectors, such as agriculture, can address critical underlying determinants of undernutrition and enhance the coverage and effectiveness of on-going nutrition-specific activities. However, evidence on how this can be done is limited. This study examines the feasibility of delivering maternal, infant, and young child nutrition behaviour change communication through an innovative agricultural extension programme serving nutritionally vulnerable groups in rural India. The existing agriculture programme involves participatory production of low-cost videos promoting best practices and broad dissemination through village-level women’s self-help groups. For the nutrition intervention, 10 videos promoting specific maternal, infant, and young child nutrition practices were produced and disseminated in 30 villages. A range of methods was used to collect data, including in-depth interviews with project staff, frontline health workers, and self-help group members and their families; structured observations of mediated video dissemination sessions; nutrition knowledge tests with project staff and self-help group members; and a social network questionnaire to assess diffusion of promoted nutrition messages. We found the nutrition intervention to be well-received by rural communities and viewed as complementary to existing frontline health services. However, compared to agriculture, nutrition content required more time, creativity, and technical support to develop and deliver. Experimentation with promoted nutrition behaviours was high, but sharing of information from the videos with non-viewers was limited. Key lessons learned include the benefits of and need for collaboration with existing health services; continued technical support for implementing partners; engagement with local cultural norms and beliefs; empowerment of women’s group members to champion

  7. Psychiatric agriculture: systemic nutritional modification and mental health in the developing world.

    London, Douglas S; Stoll, Andrew L; Manning, Bruce B

    2006-01-01

    Modernization of agricultural systems to increase output causes changes to the nutritional content of food entire populations consume. Human nutritional needs differ from their "food", thus producing healthy agricultural products is not equivalent to providing agricultural products that are healthy for humans. Inclusion of the food production system as a factor in the increase of neuropsychiatric disorders and other chronic diseases helps explain negative trends in modern chronic diseases that remain unchecked despite stunning advances in modern medicine. Diseases in which our own technology plays a significant role include obesity and resulting disorders, such as diabetes, heart disease, hypertension, stroke and arthritis. Modernization's lure leads to importation of modern agricultural practices into a nutritionally vulnerable, malnourished and sometimes starving developing world. Wealthier nations hedge their food portfolio by having access to a wider variety of foods. The developing world's reliance on staple foods means even a minor widespread nutritional modification of one key food can have profound effects. New agricultural techniques may improve or exacerbate neuropsychiatric disorders through nutritional modification in regions where populations walk a nutritional tightrope with little margin for error. In most of the developing world western psychiatric interventions have failed to make inroads. People's consumption of fish has a demonstrated beneficial effect on their mental health and the omega-3 fatty acid content is a significant factor. Epidemiological, biological and agricultural studies implicate a lack of dietary omega-3s as a factor in certain mental disorders. Replenishing omega-3s has improved mental illnesses in controlled clinical trials. This article's detailed tilapia fish-farming model demonstrates how aquaculture/agriculture techniques can function as a public health intervention by increasing dietary omega-3s through creation of

    This pilot study tested the influence of nutrition message framing on snack choice among kindergarteners. Three classrooms were randomly assigned to watch one of the following 60s videos: (a) a gain-framed nutrition message (i.e. the positive benefits of eating apples) (n=14); (b) a loss-framed message (i.e. the negative consequences of not eating apples) (n=18); or (c) a control scene (children playing a game) (n=18). Following this, the children were offered a choice between animal crackers and an apple for their snack. Among the children who saw one of the nutrition message videos, 56% chose apples rather than animal crackers; in the control condition only 33% chose apples. This difference was statistically significant (chi2=7.56, p<0.01). These results suggest that videos containing nutritional messages may have a positive influence on children's short-term food choices.

    Banana-based weaning food mixes were developed from the Nendran variety to study the nutritional quality of the mixes and feasibility of marketing on a commercial scale. Chemical composition viz., moisture, acid, pH, reducing and total sugars, protein and β-carotene of the developed banana-based weaning mixes were analysed. The trypsin inhibitor activity reduced during cooking, and the flatus compound could not be measured due to its very meagre gas production. The α-amylase activity and in vitro protein and carbohydrate digestibilities were also analysed. A feeding trial of the developed mixes was conducted in infants as a supplement to study the nutritional quality of the developed banana-based weaning food mixes. Results showed an increase in all the anthropometric measurements during the feeding period, and the developed mixes can be prepared on a commercial scale to prevent malnutrition and undernutrition during the rapid growing period of infants.

    Background Concerns have been raised about the quality of reporting in nutritional epidemiology. Research reporting guidelines such as the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement can improve quality of reporting in observational studies. Herein, we propose recommendations for reporting nutritional epidemiology and dietary assessment research by extending the STROBE statement into Strengthening the Reporting of Observational Studies in Epidemiology—Nutritional Epidemiology (STROBE-nut). Methods and Findings Recommendations for the reporting of nutritional epidemiology and dietary assessment research were developed following a systematic and consultative process, coordinated by a multidisciplinary group of 21 experts. Consensus on reporting guidelines was reached through a three-round Delphi consultation process with 53 external experts. In total, 24 recommendations for nutritional epidemiology were added to the STROBE checklist. Conclusion When used appropriately, reporting guidelines for nutritional epidemiology can contribute to improve reporting of observational studies with a focus on diet and health. PMID:27270749

    This paper discusses simple but effective methods of surveillance of growth and nutrition of children in developing countries where resources are scarce and food shortages most likely to occur. In the youngest age group, the simplest weight-for-age chart, already used, is undoubtedly the best method. Where the age of children is not known, arm circumference provides an acceptable alternative. In older children, arm circumference alone may not be reliable and can be improved by measuring height as well and combining the two results.

    The elderly population is increasing and it is well documented that may present some health problems related to nutritional intake. Both mental and physical impairments in the elderly may need specific adaptations to dietary assessment methods. But all self-report approaches include systematic and random errors, and under-reporting of dietary energy intake is common. Biomarkers of protein intake, as 24 hours urinary Nitrogen, may not be useful in elderly patients because of incontinence problems. Some micronutrients, like vitamin B12, have special importance in the elderly population. Also, measurement of fluid intake is also critical because elderly population is prone to dehydration. A detailed malnutrition status assessment should be included in the geriatric dietary history, and assessment. Body mass index (BMI) is not useful in the elderly, and it is important to evaluate functional status. Gait speed, handgrip strength using hand dynamometry can be used. Body Shape Index (ABSI) appears to be an accurate measure of adiposity, and is associated with total mortality. Further research is needed to clarify the best and simple methods to accurately estimate food and beverage fluid intake in the elderly population, and to evaluate nutritional and hidration status.

    The organisation of services to support the increasing number of people receiving enteral tube feeding (ETF) at home varies across regions. There is evidence that multi-disciplinary primary care teams focussed on home enteral nutrition (HEN) can provide cost-effective care. This paper describes the development and evaluation of a HEN Team in one UK city. A HEN Team comprising dietetians, nurses and a speech and language therapist was developed with the aim of delivering a quality service for people with gastrostomy tubes living at home. Team objectives were set and an underpinning framework of organisation developed including a care pathway and a schedule of training. Impact on patient outcomes was assessed in a pre-post test evaluation design. Patients and carers reported improved support in managing their ETF. Cost savings were realised through: (1) prevention of hospital admission and related transport for ETF related issues; (2) effective management and reduction of waste of feed and thickener; (3) balloon gastrostomy tube replacement by the HEN Team in the patient’s home, and optimisation of nutritional status. This service evaluation demonstrated that the establishment of a dedicated multi-professional HEN Team focussed on achievement of key objectives improved patient experience and, although calculation of cost savings were estimates, provided evidence of cost-effectiveness.

    Total parenteral nutrition (TPN) is widely used in premature and/or surgical neonates, but there is little information available about its effects on intestinal growth and development. Adult TPN models have demonstrated mucosal atrophy, and a young piglet model showed similar but increased intestinal hypotrophy. We have investigated these effects in the neonatal piglet model. Five three-day old piglets received a glucose (40 g/kg/d), amino acid (8 g/kg/d), and fat (4 g/kg/d) solution intravenously for 3 weeks. Matched littermates were fed an artificial sow-milk formula enterally at an equivalent caloric rate (215 kcal/kg/d). A third littermate was sow breast fed for the same study period. No differences were seen in the TPN or formula-fed piglets in weight gain (31 to 34 g/kg/d), hematocrit (25% to 27%), BUN (12 to 13 mg/dL), total serum protein (4.1 to 4.4 g/dL), or total bilirubin (0.4 to 0.6 mg/dL); however, the TPN animals were mildly hyperglycemic (167 mg/dL). The sow-fed control group had greater weight gain (51 g/kg/d) but were without caloric restriction. There were significant decreases in weight and length of the gastrointestinal tract, particularly in the proximal small bowel of the TPN piglets. Compared with formula piglets or sow-fed controls, the TPN proximal small bowel weight was reduced by 67% and 72%, respectively. Similar but less marked differences were seen in the TPN distal small bowel. There were no significant differences in the proximal or distal small bowel measurements between the formula and sow-fed piglets, despite their differences in overall weight gain.(ABSTRACT TRUNCATED AT 250 WORDS)

    We have previously reported that offspring of mothers fed a high fat (HF) diet during pregnancy and lactation enter puberty early and are hyperleptinaemic, hyperinsulinaemic and obese as adults. Poor maternal care and bonding can also impact offspring development and disease risk.We therefore hypothesized that prenatal nutrition would affect maternal care and that an interaction may exist between a maternal HF diet and maternal care, subsequently impacting on offspring phenotype.Wistar rats were mated and randomized to control dams fed a control diet (CON) or dams fed a HF diet from conception until the end of lactation (HF). Maternal care was assessed by observing maternal licking and grooming of pups between postnatal day (P)3 and P8. Postweaning (P22), offspring were fed a control (–con) or HF (–hf) diet. From P27, pubertal onset was assessed. At ∼P105 oestrous cyclicity was investigated. Maternal HF diet reduced maternal care; HF-fed mothers licked and groomed pups less than CON dams.Maternal fat:lean ratio was higher in HF dams at weaning and was associated with higher maternal plasma leptin and insulin concentrations, but there was no effect of maternal care on fat:lean ratio or maternal hormone levels. Both female and male offspring of HF dams were lighter from birth to P11 than offspring of CON dams, but by P19, HF offspring were heavier than controls. Prepubertal retroperitoneal fat mass was greater in pups from HF-fed dams compared to CON and was associated with elevated circulating leptin concentrations in females only, but there was neither an effect of maternal care, nor an interaction between maternal diet and care on prepubertal fat mass. Pups from HF-fed dams went into puberty early and this effect was exacerbated by a postweaning HF diet.Maternal and postweaning HF diets independently altered oestrous cyclicity in females: female offspring of HF-fed mothers were more likely to have prolonged or persistent oestrus, whilst female offspring fed

    Purpose This study evaluated the feasibility of developing linguistically tailored educational messages designed to match the linguistic styles of patients segmented into types with the Descriptor™, and to determine patient preferences for tailored or standard messages based on their segments. Patients and methods Twenty patients with type 2 diabetes (T2DM) were recruited from a diabetes health clinic. Participants were segmented using the Descriptor™, a language-based questionnaire, to identify patient types based on their control orientation (internal/external), agency (high/low), and affect (positive/negative), which are well studied constructs related to T2DM self-management. Two of the seven self-care behaviors described by the American Association of Diabetes Educators (healthy eating and taking medication) were used to develop standard messages and then linguistically tailored using features of the six different construct segment types of the Descriptor™. A subset of seven participants each provided feedback on their preference for standard or linguistically tailored messages; 12 comparisons between standard and tailored messages were made. Results Overall, the tailored messages were preferred to the standard messages. When the messages were matched to specific construct segment types, the tailored messages were preferred over the standard messages, although this was not statistically significant. Conclusion Linguistically tailoring messages based on construct segments is feasible. Furthermore, tailored messages were more often preferred over standard messages. This study provides some preliminary evidence for tailoring messages based on the linguistic features of control orientation, agency, and affect. The messages developed in this study should be tested in a larger more representative sample. The present study did not explore whether tailored messages were better understood. This research will serve as preliminary evidence to develop future studies

    The purposes of the study were to analyze nutritional status, psychosocial stimulation, and factors affecting the cognitive development of preschool-age children. This study was conducted in the Village of Babakan, Sub-District of Dramaga, Bogor Regency, West Java. This cross-sectionally designed study was conducted with mothers who had preschool children aged 3-5 years as respondents. Fifty-eight children were included. The distribution of mother's educational level was quite diverse, and the largest percentage (44.8%) had senior high school education. Approximately 78% of the family income per capita was classified into the non-poor category and 22.4% into the poor category. The average mother's nutritional knowledge score was 76.7 ± 2.5 (moderate category). Most of the preschool children (84.4%) had psychosocial stimulation scores in the moderate category (30-45). The nutritional status of children showed that 15.5% were underweight, 5.2% were wasted, 3.4% were severely wasted, and 19% of the children were in the short and very short categories (stunted). The stepwise regression results showed that psychosocial stimulation (P < 0.001), participation in early childhood education (P = 0.002) and nutritional status based on the height index for age (P = 0.028) had a positive and significant effect on cognitive development of the preschool children (adjusted R(2), 0.434; P = 0.028).

    An increased consumption of healthy foods to reduce chronic diseases risks is needed. We developed and evaluated a multigrain snack as a nutritive alternative to the highly consumed corn tortilla chips. Corn, wheat, and chickpea grains were boiled in 1% calcium oxide solution, steeped, washed, and ground before being mixed with soy protein isolate and oat flour to prepare the multigrain masa. Multigrain tortillas were moulded, baked, dried, and fried. Proximate composition, dietary fiber, protein quality, sensorial, and textural properties were evaluated. A commercial tortilla chip was used as control. The multigrain snack contained 153% more protein, 53% more dietary fiber, and 43 % less fat than commercial tortilla chips. Its lysine and isoleucine contents helped to increase the corrected-net protein utilization by 10%, while digestibility increased from 83.5 to 91.8% as compared to commercial tortilla chips. The mean breaking force was 6,082 g for the multigrain snack and 4,780 g for the commercial tortilla chips. The mean acceptability score for the multigrain snack was 12.1 (unstructured line scale 0-15 cm), and 82% of the panelists rated the snack as acceptable. In conclusion, a nutritionally enhanced multigrain tortilla snack was developed which provides significantly more dietary fiber and protein and less fat than traditional commercial corn tortilla chips, but with comparable appearance and high acceptability.

    The Biomarkers of Nutrition for Development (BOND) project is designed to provide evidence-informed advice to anyone with an interest in the role of nutrition in health. The BOND program provides information with regard to selection, use, and interpretation of biomarkers of nutrient exposure, status, function, and effect, which will be especially useful for readers who want to assess nutrient status. To accomplish this objective, expert panels are recruited to evaluate the literature and to draft comprehensive reports on the current state of the art with regard to specific nutrient biology and available biomarkers for assessing nutritional status at the individual and population levels. Phase I of the BOND project includes the evaluation of biomarkers for 6 nutrients: iodine, folate, zinc, iron, vitamin A, and vitamin B-12. This review of vitamin A is the current article in this series. Although the vitamin was discovered >100 y ago, vitamin A status assessment is not trivial. Serum retinol concentrations are under homeostatic control due in part to vitamin A's use in the body for growth and cellular differentiation and because of its toxic properties at high concentrations. Furthermore, serum retinol concentrations are depressed during infection and inflammation because retinol-binding protein (RBP) is a negative acute-phase reactant, which makes status assessment challenging. Thus, this review describes the clinical and functional indicators related to eye health and biochemical biomarkers of vitamin A status (i.e., serum retinol, RBP, breast-milk retinol, dose-response tests, isotope dilution methodology, and serum retinyl esters). These biomarkers are then related to liver vitamin A concentrations, which are usually considered the gold standard for vitamin A status. With regard to biomarkers, future research questions and gaps in our current understanding as well as limitations of the methods are described. PMID:27511929

    The environment in which a breeding female lives prior to conception and during the early stages of her pregnancy has striking effects on oocytes developing in the ovarian follicle and on early embryos in the reproductive tract. Of the various environmental factors known to affect oocyte and embryo development, altered nutrition during this critical period has been particularly well studied. Alterations in the quantity of food consumed or the composition of the diet imposed solely during the pre-mating period affect oocyte maturity, blastocyst yield, prenatal survival and the number of offspring born alive. Importantly, nutrition at this time also affects the quality of embryos and resultant offspring, with increasing evidence from a variety of species showing that peri-conception nutrition can alter behaviour, cardiovascular function and reproductive function throughout post-natal life. In livestock species, it is important to devise nutritional strategies that improve reproductive efficiency and the quality of offspring but that do not add to the environmental footprint of the production system and which recognize likely changes in feedstuff availability arising from predicted changes in climate.

    Multifaceted community interventions directed at improving food environments are emerging, but their impact on dietary change and obesity prevalence has not been adequately documented. The Healthy Communities Study (HCS) is seeking to identify characteristics and combinations of programs and policies that are associated with children's diets and obesity-related outcomes in various types of communities across the U.S. The purpose of this paper is to describe the methods used in 2013-2015 in the HCS to assess dietary intake, school nutrition environments, and other nutrition-related behaviors. The conceptual framework of the HCS is based on the socioecological model and behaviors shown in previous studies to be related to obesity in children guided selection of domains. Nine domains were identified as essential measures of nutrition in the HCS: (1) intake of selected foods and beverages; (2) food patterns and behaviors; (3) social support; (4) home environment; (5) school environment; (6) community environment; (7) breastfeeding history; (8) household food insecurity; and (9) dieting behaviors and body image. Children's dietary intake was assessed using a dietary screener and up to two automated 24-hour recalls. Dietary-related behaviors were assessed by a survey administered to the parent, child, or both, depending on child age. School nutrition measures were obtained from a combination of school staff surveys and researcher observations. Information from these measures is expected to contribute to a better understanding of "what is working" to improve the dietary behaviors that are likely to prevent obesity and improve health in children.

    Nutritional studies including food and beverage consumption assessment are needed for different purposes in the field of nutrition, food supply monitoring, toxicology or in the context of intervention strategies that include changes in eating behaviors. Different methods have been used, each with strengths, weaknesses, biases and limitations that must be considered when choosing the most appropriate in each case. The development of new technologies offers exciting developments to improve the validity and accuracy of these methods, as well as their efficiency and commodity. The characteristics of the individuals under study, its environment and the resources available should be considered as well.

    It is the position of the Academy of Nutrition and Dietetics that all people should have consistent access to an appropriately nutritious diet of food and water, coupled with a sanitary environment, adequate health services, and care that ensure a healthy and active life for all household members. The Academy supports policies, systems, programs, and practices that work with developing nations to achieve nutrition security and self-sufficiency while being environmentally and economically sustainable. For nations to achieve nutrition security, all people must have access to a variety of nutritious foods and potable drinking water; knowledge, resources, and skills for healthy living; prevention, treatment, and care for diseases affecting nutrition status; and safety-net systems during crisis situations, such as natural disasters or deleterious social and political systems. More than 2 billion people are micronutrient deficient; 1.5 billion people are overweight or obese; 870 million people have inadequate food energy intake; and 783 million people lack potable drinking water. Adequate nutrient intake is a concern, independent of weight status. Although this article focuses on nutritional deficiencies in developing nations, global solutions for excesses and deficiencies need to be addressed. In an effort to achieve nutrition security, lifestyles, policies, and systems (eg, food, water, health, energy, education/knowledge, and economic) contributing to sustainable resource use, environmental management, health promotion, economic stability, and positive social environments are required. Food and nutrition practitioners can get involved in promoting and implementing effective and sustainable policies, systems, programs, and practices that support individual, community, and national efforts.

  9. The Change in Nutritional Status in Traumatic Brain Injury Patients: A Retrospective Descriptive Study

    NASA Astrophysics Data System (ADS)

    Masha'al, Dina A.

    There is a high prevalence in malnutrition among traumatic brain injury (TBI) due to the hypermetabolism and hypercatabolism which develop post injury. Traumatic brain injury patients are different, even among themselves, in their energy requirements and response to nutritional therapy. This implies that there are other factors that affect the energy intake of these patients and enhance the incidence of malnutrition. This dissertation study examines the nutritional status of TBI patients upon admission to the intensive care unit (ICU) and during their hospital stay to describe baseline status, detect changes in nutritional status over 7 days, and identify the factors affecting the adequacy of energy intake and the change in nutritional status as a consequence. Anthropometric measurements, biomedical measurements, measures of severity of illness, daily health status, level of brain injury severity, and other data were collected from the medical records of 50 patients, who were ≥ 18 years old, mechanically ventilated in the first 24 hours of ICU admission, and had a Glasgow Coma Scale score between 3-12. These data were used to examine the previous relationships. Although there was no statistically significant change found in body mass index and weight, there was a significant change detected in other nutritional markers, including hemoglobin, albumin, and total lymphocyte levels over the 7 days of ICU and hospital stay. No significant relationship was found between the adequacy of energy intake and total prescribed energy, severity of illness, level of brain injury severity, daily health status, patient age, intracranial pressure, or time of feeding initiation. Findings may be used to develop and test interventions to improve nutritional status during the acute phase of TBI. This will lay a foundation for health care providers, including nurses, to establish standards for practice and nutrition protocols to assure optimal nutrition assessment and intervention in a

  10. Influence of metabolic hormones and nutrition on ovarian follicle development in cattle: practical implications.

    PubMed

    Gong, J G

    2002-07-01

    Nutrition has long been known to have a profound influence on reproductive performance of female cattle, but the underlying mechanism remains poorly understood. Whilst early investigations focused on the modulation of nutrition on hypothalamic-pituitary axis, more recent studies have tested the hypothesis that metabolic hormones as nutritional signals exert a direct effect at the ovarian level. In cattle, treatment with recombinant bovine somatotrophin (rGH) significantly increases the population of small ovarian follicles. This is associated with increases in circulating concentrations of insulin and insulin-like growth factor-I (IGF-I). Subsequent studies, both in vitro and in vivo, have highlighted the importance of IGF-I and/or insulin acting in synergy with FSH and LH. More recently, we demonstrated that feeding heifers with 200% maintenance requirements for a short period significantly increases circulating insulin concentrations and population of small ovarian follicles. Based on these findings, our recent work has aimed at addressing some practical problems in cattle production. Firstly, we showed that both rGH pretreatment and increased dietary intake significantly enhance the response to standard superovulatory regimes. Secondly, we have demonstrated that feeding a diet to increase circulating insulin concentrations during the early lactation can advance the first ovulation postpartum and increase conception rate to the first service in dairy cows. In summary, nutrition influences ovarian follicle development in cattle possibly through changes in metabolic hormones. These interactions can be manipulated to improve reproductive performance.

    There is convincing epidemiological and clinical evidence that, independent of aging, lifestyle and, notably, nutrition are associated with development or progression of major human cancers, including breast, prostate, colorectal tumors, and an increasingly large collection of diet-related cancers. Mechanisms underlying this association are mostly related to the distinct epigenetic effects of different dietary patterns. In this context, Mediterranean diet has been reported to significantly reduce mortality rates for various chronic illnesses, including cardiovascular diseases, neurodegenerative diseases and cancer. Although many observational studies have supported this evidence, dietary intervention studies using a Mediterranean dietary pattern or its selected food components are still limited and affected by a rather large variability in characteristics of study subjects, type and length of intervention, selected end-points and statistical analysis. Here we review data of two of our intervention studies, the MeDiet study and the DiMeSa project, aimed at assessing the effects of traditional Mediterranean diet and/or its component(s) on a large panel of both plasma and urine biomarkers. Both published and unpublished results are presented and discussed. PMID:27057203

    OBJECTIVE The purpose of this study was to develop a survey of general and diabetes-specific nutrition knowledge for youth with type 1 diabetes and their parents and to assess the survey’s psychometric properties. RESEARCH DESIGN AND METHODS A multidisciplinary pediatric team developed the Nutrition Knowledge Survey (NKS) and administered it to youth with type 1 diabetes (n = 282, 49% females, 13.3 ± 2.9 years) and their parents (82% mothers). The NKS content domains included healthful eating, carbohydrate counting, blood glucose response to foods, and nutrition label reading. Higher NKS scores reflect greater nutrition knowledge (score range is 0–100%). In youths, glycemic control was assessed by A1C, and dietary quality was determined by the Healthy Eating Index-2005 (HEI-2005) derived from 3-day diet records. Validity was based on associations of NKS scores with A1C and dietary quality. Reliability was assessed using the Kuder-Richardson Formula 20 (KR-20) and correlations of domain scores to total score. RESULTS Mean NKS scores (23 items) were 56.9 ± 16.4% for youth and 73.4 ± 12.5% for parents. The KR-20 was 0.70 for youth and 0.59 for parents, representing acceptable internal consistency of the measure. In multivariate analysis, controlling for youth age, family income, parent education, diabetes duration, and insulin regimen, parent NKS scores were associated with corresponding youth A1C (β = −0.13, P = 0.03). Both parent (β = 0.20, P = 0.002) and youth (β = 0.25, P < 0.001) NKS scores were positively associated with youth HEI-2005 scores. CONCLUSIONS The NKS appears to be a useful measure of general and diabetes-specific nutrition knowledge for youth with type 1 diabetes and their parents. PMID:22665217

    A prospective study of nutritional support during pelvic irradiation was carried out in 32 patients with a primary pelvic malignancy and prior weight loss. Both curative and palliative patients were eligible for the study. Seventeen patients were randomized to receive intravenous hyperalimentation (IVH) and fifteen patients served as controls who were maintained on their regular diet. Patients were stratified by percent body weight loss. Tolerance to therapy was assessed by evaluation of functional status and by using nutritional parameters of body weight change, change in serum protein levels, and response to delayed hypersensitivity skin tests. The curative IVH group tolerated therapy well by both functional and nutritional measurements. All curative IVH patients completed the planned radiation therapy without a treatment break and were fully active following treatment. Patients gained an average of 4.0 kg body weight during irradiation, which was significantly different from the curative control patients. They demonstrated a significant increase in serum transferrin reflecting an improvement in visceral protein. In addition, all showed a positive response to delayed hypersensitivity skin tests at the completion of irradiation. The palliative IVH patients often did poorly because of progression of disease and demonstrated only an elevation of serum transferrin during treatment. The results in the curative IVH group suggest a potential adjunctive role for intravenous hyperalimentation in the malnourished cancer patient undergoing pelvic irradiation. Clearly, further study of nutritional support during pelvic irradiation is needed using curative patients with a single tumor type and significant prior weight loss.

    Background Social networking sites (SNSs) such as Facebook have the potential to enhance online public health interventions, in part, as they provide social exposure and reinforcement. Objective The objective of the study was to evaluate whether social exposure provided by SNSs enhances the effects of online public health interventions. Methods As a sample intervention, we developed Food Hero, an online platform for nutritional education in which players feed a virtual character according to their own nutritional needs and complete a set of virtual sport challenges. The platform was developed in 2 versions: a "private version" in which a user can see only his or her own score, and a "social version" in which a user can see other players’ scores, including preexisting Facebook friends. We assessed changes in participants’ nutritional knowledge using 4 quiz scores and 3 menu-assembly scores. Monitoring feeding and exercising attempts assessed engagement with the platform. Results The 2 versions of the platform were randomly assigned between a study group (30 members receiving the social version) and a control group (33 members, private version). The study group's performance on the quizzes gradually increased over time, relative to that of the control group, becoming significantly higher by the fourth quiz (P=.02). Furthermore, the study group's menu-assembly scores improved over time compared to the first score, whereas the control group's performance deteriorated. Study group members spent an average of 3:40 minutes assembling each menu compared to 2:50 minutes in the control group, and performed an average of 1.58 daily sport challenges, compared to 1.21 in the control group (P=.03). Conclusions This work focused on isolating the SNSs' social effects in order to help guide future online interventions. Our results indicate that the social exposure provided by SNSs is associated with increased engagement and learning in an online nutritional educational platform

    2013-01-01

    Concerns about the increasing rates of obesity in developing countries have led many policy makers to question the impacts of maternal and early child nutrition on risk of later obesity. The purposes of the review are to summarise the studies on the associations between nutrition during pregnancy and infant feeding practices with later obesity from childhood through adulthood and to identify potential ways for preventing obesity in developing countries. As few studies were identified in developing countries, key studies in developed countries were included in the review. Poor prenatal dietary intakes of energy, protein and micronutrients were shown to be associated with increased risk of adult obesity in offspring. Female offspring seem to be more vulnerable than male offspring when their mothers receive insufficient energy during pregnancy. By influencing birthweight, optimal prenatal nutrition might reduce the risk of obesity in adults. While normal birthweights (2500-3999 g) were associated with higher body mass index (BMI) as adults, they generally were associated with higher fat-free mass and lower fat mass compared with low birthweights (<2500 g). Low birthweight was associated with higher risk of metabolic syndrome and central obesity in adults. Breastfeeding and timely introduction of complementary foods were shown to protect against obesity later in life in observational studies. High-protein intake during early childhood however was associated with higher body fat mass and obesity in adulthood. In developed countries, increased weight gain during the first 2 years of life was associated with a higher BMI in adulthood. However, recent studies in developing countries showed that higher BMI was more related to greater lean body mass than fat mass. It appears that increased length at 2 years of age was positively associated with height, weight and fat-free mass, and was only weakly associated with fat mass. The protective associations between breastfeeding

    The primary objective of this pilot study is to provide evidence that a budget-tailored culinary nutrition program is both appropriate and applicable to undergraduate food science students both in everyday life as well as their future health careers. Two validated programs were combined into one program in order to evaluate their combined effects: Cooking With a Chef and Cooking Matters at the Store. The secondary objective of this pilot study is to evaluate the components and reliability of a questionnaire created specifically for this pilot study. A review of past literature was written, which included culinary nutrition as a source of primary prevention, the importance of incorporating cost with culinary nutrition, and the importance of incorporating cost with culinary nutrition. Based on the literature review, it was determined that a budget-tailored culinary nutrition program was appropriate and applicable to undergraduate food science students interested in pursuing health-related careers. The pilot study design was a semi-crossover study: all four groups received the program, however, two groups were first treated as the control groups. All fifty-four participants received 5 sessions of culinary nutrition information from Cooking With a Chef, collaboratively delivered by a nutrition educator and a chef, and one session of information about shopping healthy on a budget from Cooking Matters at the Store in the form of a grocery store tour led by the nutrition educator. Three questionnaires were administered to the participants that evaluated culinary nutrition and price knowledge, cooking attitudes, and opinions of the programs' relevance to participants' everyday lives and careers. Two of the questionnaires, including a questionnaire developed specifically for the pilot study, were delivered as a pre- and post-test while the third questionnaire was delivered as a post-test. Eight random participants also partook in a focus group session led by the nutrition

    The Texas Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) sought to engage the WIC staff and community in the implementation of relevant and effective client-centered nutrition education. The program was implemented in a 4-stage framework. The collaborative process of developing client-centered nutrition education allowed members to learn from one another, thus ensuring commitment to client-centered nutrition education from all levels of staff. The co-created materials and trainings developed during the implementation played a key role. Evaluation feedback started at the infancy of implementation and gave all community members a stake in developing client-centered nutrition education and an opportunity to be invested in its success, which led to increased execution at the local agency level over the implementation stages.

    On the analysis of the factual energy expenditure by cosmonauts during extravehicular activities two choices of special rations (SR) were developed. Hygienic testing showed that all nutritional components in these SRs were present in optimal quantities. Consumption of the SR foods during any basic meal will not misbalance the latter but satisfy the body demand of the main indispensable nutritional factors.

    Nutritional geometry has shown the benefits of viewing nutrition in a multidimensional context, in which foraging is viewed as a process of balancing the intake and use of multiple nutrients. New insights into nutrient regulation have been generated in studies performed in a laboratory context, where accurate measures of amounts (e.g. eaten, converted to body mass, excreted) can be made and analysed using amounts-based nutritional geometry. In most field situations, however, proportional compositions (e.g. of foods, diets, faeces) are the only measures readily available, and in some cases are more relevant to the problem at hand. For this reason, a complementary geometric method was recently introduced for analysing multi-dimensional data on proportional compositions in nutritional studies, called the right-angled mixture triangle (RMT). We use literature data from field studies of primates to demonstrate how the RMT can provide insight into a variety of important concepts in nutritional ecology. We first compare the compositions of foods, using as an example primate milks collected in both the wild and the laboratory. We next compare the diets of different species of primates from the same habitat and of the same species (mountain gorillas) from two distinct forests. Subsequently, we model the relationships between the composition of gorilla diets in these two habitats and the foods that comprise these diets, showing how such analyses can provide evidence for active nutrient-specific regulation in a field context. We provide a framework to relate concepts developed in laboratory studies with field-based studies of nutrition.

  13. Nutrition intervention strategies to combat zinc deficiency in developing countries.

    1998-06-01

    Widespread zinc deficiency is likely to exist in developing countries where staple diets are predominantly plant based and intakes of animal tissues are low. The severe negative consequences of zinc deficiency on human health in developing countries, however, have only recently been recognized. An integrated approach employing targeted supplementation, fortification and dietary strategies must be used to maximize the likelihood of eliminating zinc deficiency at a national level in developing countries. Supplementation is appropriate only for populations whose zinc status must be improved over a relatively short time period, and when requirements cannot be met from habitual dietary sources. As well, the health system must be capable of providing consistent supply, distribution, delivery and consumption of the zinc supplement to the targeted groups. Uncertainties still exist about the type, frequency, and level of supplemental zinc required for prevention and treatment of zinc deficiency. Salts that are readily absorbed and at levels that will not induce antagonistic nutrient interactions must be used. At a national level, fortification with multiple micronutrients could be a cost effective method for improving micronutrient status, including zinc, provided that a suitable food vehicle which is centrally processed is available. Alternatively, fortification could be targeted for certain high risk groups (e.g. complementary foods for infants). Efforts should be made to develop protected fortificants for zinc, so that potent inhibitors of zinc absorption (e.g. phytate) present either in the food vehicle and/or indigenous meals do not compromise zinc absorption. Fortification does not require any changes in the existing food beliefs and practices for the consumer and, unlike supplementation, does not impose a burden on the health sector. A quality assurance programme is required, however, to ensure the quality of the fortified food product from production to consumption

  14. The nutrition transition and obesity in the developing world.

    2001-03-01

    Changes in diet and activity patterns are fueling the obesity epidemic. These rapid changes in the levels and composition of dietary and activity/inactivity patterns in transitional societies are related to a number of socioeconomic and demographic changes. Using data mainly from large nationally representative and nationwide surveys, such as the 1989, 1991, 1993 and 1997 China Health and Nutrition Surveys, in combination with comparative analysis across the regions of the world, we examine these factors. First, we show the shifts in diet and activity are consistent with the rapid changes in child and adult obesity and in some cases have been causally linked. We then provide a few examples of the rapid changes in the structure of diet and activity, in particular associated with increased income. Cross-country and in-depth analysis of the China study are used to explore these relationships. People living in urban areas consume diets distinctly different from those of their rural counterparts. One of the more profound effects is the accelerated change in the structure of diet, only partially explained by economic factors. A second is the emergence of a large proportion of families with both currently malnourished and overweight members as is shown by comparative analysis of a number of Asian and Latin American countries.

    The cases of Mexico, Kenya, and India are described to illustrate the difficulty of assuring national food supplies in the face of rapid population growth. In 1985, despite a world cereal surplus, some 700 million of the earth's poorest inhabitants lacked sufficient food to support a normal life, and some 17 million children died of malnutrition or diseases aggravated by malnutrition. 16% of today's Third World population lacks sufficient food to maintain health. Rapid population growth is a cause of hunger in both countries and households. In already densely populated countries such as Bangladesh, population growth reduces the availability of agricultural land for each rural family, causing rural incomes to decrease and worsening rural unemployment. Few developing countries have been able to avoid serious urban unemployment and underemployment. Unstable governments try to calm urban unrest by concentrating all social and economic investment in the cities, causing suffering and diminished production in the countryside. Today more than 60 countries have food deficits. The majority of them are poor and becoming poorer. India, Kenya, and Mexico have had relative success in balancing food production and population growth, but each still has malnutrition due to inadequate economic policies for most of the poor and to implacable population growth. India's population of 785 million is growing at a rate of 2.3%/year. 1984 per capita calorie consumption was 92% of the required minimum. The poorest 20% of the population shared 7% of total household income. Since 1950 food production in India has almost tripled, but population nearly doubled in the same years. Poor food distribution and unequal agricultural progress have meant that malnutrition continues to plague India. Approximately 45% of the population suffered some degree of malnutrition in 1986. It is unlikely that India's future agricultural progress will be as rapid as that of the past 3 decades. Erosion

    Investment in nutritional programmes can contribute to economic growth and is cost-effective in improving child survival and development. In order to communicate this to decision-makers, the PROFILES nutrition advocacy and policy development programme was applied in certain developing countries. Effective advocacy is necessary to generate financial and political support for scaling up from small pilot projects and maintaining successful national programmes. The programme uses scientific knowledge to estimate development indicators such as mortality, morbidity, fertility, school performance and labour productivity from the size and nutritional condition of populations. Changes in nutritional condition are estimated from the costs, coverage and effectiveness of proposed programmes. In Bangladesh this approach helped to gain approval and funding for a major nutrition programme. PROFILES helped to promote the nutrition component of an early childhood development programme in the Philippines, and to make nutrition a top priority in Ghana's new national child survival strategy. The application of PROFILES in these and other countries has been supported by the United States Agency for International Development, the United Nations Children's Fund, the World Bank, the Asian Development Bank, the Micronutrient Initiative and other bodies.

    Adequate nutrition is critical during long-term spaceflight, as is the ability to easily monitor dietary intake. A comprehensive nutritional status assessment profile was designed for use before, during and after flight. It included assessment of both dietary intake and biochemical markers of nutritional status. A spaceflight food-frequency questionnaire (FFQ) was developed to evaluate intake of key nutrients during spaceflight. The nutritional status assessment protocol was evaluated during two ground-based closed-chamber studies (60 and 91 d; n = 4/study), and was implemented for two astronauts during 4-mo stays on the Mir space station. Ground-based studies indicated that the FFQ, administered daily or weekly, adequately estimated intake of key nutrients. Chamber subjects maintained prechamber energy intake and body weight. Astronauts tended to eat 40--50% of WHO-predicted energy requirements, and lost >10% of preflight body mass. Serum ferritin levels were lower after the chamber stays, despite adequate iron intake. Red blood cell folate concentrations were increased after the chamber studies. Vitamin D stores were decreased by > 40% on chamber egress and after spaceflight. Mir crew members had decreased levels of most nutritional indices, but these are difficult to interpret given the insufficient energy intake and loss of body mass. Spaceflight food systems can provide adequate intake of macronutrients, although, as expected, micronutrient intake is a concern for any closed or semiclosed food system. These data demonstrate the utility and importance of nutritional status assessment during spaceflight and of the FFQ during extended-duration spaceflight.

    This review examines the current evidence for a possible connection between nutritional intake (including micronutrients and whole diet) and neurocognitive development in childhood. Earlier studies which have investigated the association between nutrition and cognitive development have focused on individual micronutrients, including omega-3 fatty acids, vitamin B12, folic acid, choline, iron, iodine, and zinc, and single aspects of diet. The research evidence from observational studies suggests that micronutrients may play an important role in the cognitive development of children. However, the results of intervention trials utilizing single micronutrients are inconclusive. More generally, there is evidence that malnutrition can impair cognitive development, whilst breastfeeding appears to be beneficial for cognition. Eating breakfast is also beneficial for cognition. In contrast, there is currently inconclusive evidence regarding the association between obesity and cognition. Since individuals consume combinations of foods, more recently researchers have become interested in the cognitive impact of diet as a composite measure. Only a few studies to date have investigated the associations between dietary patterns and cognitive development. In future research, more well designed intervention trials are needed, with special consideration given to the interactive effects of nutrients. PMID:23532379

    There is growing evidence of the effectiveness of early childhood interventions to improve the growth and development of children. Although, historically, nutrition and stimulation interventions may have been delivered separately, they are increasingly being tested as a package of early childhood interventions that synergistically improve outcomes over the life course. However, implementation at scale is seldom possible without first considering the relative cost and cost-effectiveness of these interventions. An evidence gap in this area may deter large-scale implementation, particularly in low- and middle-income countries. We conduct a literature review to establish what is known about the cost-effectiveness of early childhood nutrition and development interventions. A set of predefined search terms and exclusion criteria standardized the search across five databases. The search identified 15 relevant articles. Of these, nine were from studies set in high-income countries and six in low- and middle-income countries. The articles either calculated the cost-effectiveness of nutrition-specific interventions (n = 8) aimed at improving child growth, or parenting interventions (stimulation) to improve early childhood development (n = 7). No articles estimated the cost-effectiveness of combined interventions. Comparing results within nutrition or stimulation interventions, or between nutrition and stimulation interventions was largely prevented by the variety of outcome measures used in these analyses. This article highlights the need for further evidence relevant to low- and middle-income countries. To facilitate comparison of cost-effectiveness between studies, and between contexts where appropriate, a move towards a common outcome measure such as the cost per disability-adjusted life years averted is advocated. Finally, given the increasing number of combined nutrition and stimulation interventions being tested, there is a significant need for evidence of cost

    This pilot study examined the effectiveness of a 4-month clinic-based dietary intervention emphasizing the intake of deep yellow and dark green vegetables versus usual care on improving diet quality in postpartum women. The intervention group (n = 31) received 1 face-to-face nutrition education session with a registered dietitian, 2 follow-up phone calls, and 3 pamphlets distributed by mail. The usual care group (n = 25) received handouts with guidelines on healthy eating. Dietary outcomes were assessed from 3-day food recalls and evaluated using paired and independent t tests. Intervention women exhibited a significant increase in total vegetable intake (P < .001) and in dark green and deep yellow vegetables (P < .001). In comparison, the control group increased the intake of total vegetables (P < .001), but did not increase the consumption of dark green and deep yellow vegetables. When comparing the change in intake between study groups for both types of vegetables, the difference was not significant. Furthermore, 61% of the intervention women met the goals for total vegetable intake compared with 12% for the usual care group (P < .001). The intervention group also had a greater percentage of women (25.8%) that met the goal for deep yellow and dark green vegetable intake when compared with the usual care group (8%; P < .08). These results suggest that postpartum women are receptive to nutrition education and that nutrition education can influence vegetable intake.

    2012-07-01

    This review paper highlights mechanisms for nutritional regulation of maternal health and fetal development. Malnutrition (nutrient deficiencies or obesity) in pregnant women adversely affects their health by causing or exacerbating a plethora of problems, such as anaemia, maternal haemorrhage, insulin resistance, and hypertensive disorders (e.g. pre-eclampsia/eclampsia). Maternal malnutrition during gestation also impairs embryonic and fetal growth and development, resulting in deleterious outcomes, including intrauterine growth restriction (IUGR), low birthweight, preterm birth, and birth defects (e.g. neural tube defects and iodine deficiency disorders). IUGR and preterm birth contribute to high rates of neonatal morbidity and mortality. Major common mechanisms responsible for malnutrition-induced IUGR and preterm birth include: (i) abnormal growth and development of the placenta; (ii) impaired placental transfer of nutrients from mother to fetus; (iii) endocrine disorders; and (iv) disturbances in normal metabolic processes. Activation of a series of physiological responses leading to premature and sustained contraction of the uterine myometrium also results in preterm birth. Recent epidemiologic studies have suggested a link between IUGR and chronic metabolic disease in children and adults, and the effects of IUGR may be carried forward to subsequent generations through epigenetics. While advanced medical therapies, which are generally unavailable in low-income countries, are required to support preterm and IUGR infants, optimal nutrition during pregnancy may help ameliorate many of these problems. Future studies are necessary to develop effective nutritional interventions to enhance fetal growth and development and alleviate the burden of maternal morbidity and mortality in low- and middle-income countries.

Urea and NH4 in low concentration, asparagine, and lysine were very good N sources. Several other amino acids were also utilized but growth was less abundant. Inorganic and organic phosphates were utilized; they were required at relatively low concentrations. Glycerophosphate gave excellent growth in a comparatively wide range of concentrations (0.1-5 mg P %). The optimal Ca concentration was 10-100 mg %. Needs for boron, manganese, zinc, strontium, rubidium, lithium, and iodine were demonstrated. The iodine effect was remarkable (peak growth with 1μg %); the effective concentration range was very narrow. Iron, cobalt, and bromine seemed to be adequately supplied as impurities of the macro-nutrients. A modified artificial medium (ASP12 I) for the Conchocelis phase is presented.

    Alzheimer's disease (AD) is a multi-factorial neurodegenerative disorder and the leading cause of dementia, wherein synapse loss is the strongest structural correlate with cognitive impairment. Basic research has shown that dietary supply of precursors and co-factors for synthesis of neuronal membranes enhances the formation of synapses. Daily intake of a medical food containing a mix of these nutrients for 12 weeks in humans improved memory, measured as immediate and delayed verbal recall by the Wechsler Memory Scale-revised, in patients with very mild AD (MMSE 24-26). An improvement of immediate verbal recall was noted following 24 weeks of intervention in an exploratory extension of the study. These data suggest that the intervention may improve synaptic formation and function in early AD. Here we review emerging technologies that help identify changes in pathological hallmarks in AD, including synaptic function and loss of connectivity in the early stages of AD, before cognitive and behavioural symptoms are observable. These techniques include the detection of specific biomarkers in the cerebrospinal fluid, as well as imaging procedures such as fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET), amyloid PET, structural/functional magnetic resonance imaging, diffusion tensor imaging, magnetoencephalography (MEG) and electroencephalography (EEG). Such techniques can provide new insights into the functional and structural changes in the brain over time, and may therefore help to develop more effective AD therapies. In particular, nutritional intervention studies that target synapse formation and function may benefit from these techniques, especially FDG-PET and EEG/MEG employed in the preclinical or early stages of the disease.

    Poor nutrition (substandard diet quantity and/or quality resulting in under- or overnutrition) and the lack of early learning opportunities contribute to the loss of developmental potential and life-long health and economic disparities among millions of children aged <5 y. Single-sector interventions representing either early child development (ECD) or nutrition have been linked to positive child development and/or nutritional status, and recommendations currently advocate for the development and testing of integrated interventions. We reviewed the theoretical and practical benefits and challenges of implementing integrated nutrition and ECD interventions along with the evidence for best practice and benefit-cost and concluded that the strong theoretical rationale for integration is more nuanced than the questions that the published empirical evidence have addressed. For example, further research is needed to 1) answer questions related to how integrated messaging influences caregiver characteristics such as well-being, knowledge, and behavior and how these influence early child nutrition and development outcomes; 2) understand population and nutritional contexts in which integrated interventions are beneficial; and 3) explore how varying implementation processes influence the efficacy, uptake, and cost-benefit of integrated nutrition and ECD interventions.

Changes in our dentition and facial appearance are caused by changing our diet from primitive hunter gatherer to a more modern industrialized agriculture. Nutrition and its impact on epigeneticaly- mediated mechanisms continuously shape our phenotype which impacts overall health and can reverse the path for overall health and facial bone development. Orthodontics and nutrition both play a role in following nature's path to reestablishing facial balance and dental arches proportions to accommodate all 32 teeth. PMID:27319035

    A key step toward developing appropriate evidence-based public health nutrition policies is determining exactly how that evidence should be collected and assessed. Despite this the extent to which different evidence bases influence policy selection is rarely explored. This article presents an epistemological framework which offers a range of considerations affecting this process generally and with particular implications for both micronutrient requirements and the role of behavior in the policy-making process. Qualitative case study data covering 6 European countries/regions (Czech Republic, Italy, the Netherlands, Nordic countries, Poland, and Spain), and three micronutrients (folate, iodine, and vitamin D), have been presented to illustrate the relevance of the Framework.

    This review addresses recent relevant advances to clinical nutrition regarding gastrointestinal disease surgery. Medline Ovid, EMBASE and Central were searched systematically in April 2014. Inclusion criteria were randomized controlled trials, non-randomized controlled trials and observational studies evaluating nutritional support in gastrointestinal surgery published within 5 years. The review included 56 relevant studies. Themes were: nutrition screening and risk factors predict outcome; preoperative nutritional support; shortening fasting periods and including carbohydrate solutions; early nutrition after surgery; immune modulating nutrition; synbiotics, growth hormone, omega-3 and oral, enteral and parenteral nutrition in combination. Screening for nutritional risk is profound, with special focus on dietary intake in the past week. Age and severity of disease need to be included in the screening system. Patients at severe nutritional risk benefit from nutritional therapy before surgery. New standards are developing quickly and clinical guidelines on surgery should include updated knowledge within clinical nutrition.

    The aims of this study were to document the extent of nutritional content in U.S. dental hygiene program curricula; identify program directors' opinions, perceptions, and barriers to expanding nutritional content; and evaluate if a proposed nutrition curriculum model would be beneficial. This mixed methods study involved quantitative and qualitative aspects. An invitation letter was sent to all 335 directors of entry-level U.S. dental hygiene programs. In response, 55 directors submitted nutrition course syllabi from their programs (16.4% of the total) for the quantitative analysis. In addition, 14 nutrition instructors and ten program directors were interviewed regarding their perceptions and opinions of nutrition education for dental hygiene students. All aspects of the content analysis results revealed that nutrition content in entry-level dental hygiene programs is diverse. Some programs did not include nutrition content, while others provided oral and systemic nutrition intervention subject matter. Some programs offered multiple clinical nutrition applications and patient contact opportunities while most required none. The interview results disclosed a variety of opinions and perceptions of dental hygienists' role in nutrition. Several interviewees viewed dental hygienists' role in nutrition to be an integral part of patient care, while others indicated no role or providing caries prevention counseling only. Although dental hygienists are expected to provide nutrition assessments and interventions, no standards or standardized competencies exist for nutrition in dental hygiene education. A standardized nutrition model could be beneficial for entry-level programs to ensure dental hygienists possess basic knowledge to perform nutrition assessments and intervention to address Healthy People 2020's intervention initiatives.

    It is widely appreciated that larvae of the nematode Caenorhabditis elegans arrest development by forming dauer larvae in response to multiple unfavorable environmental conditions. C. elegans larvae can also reversibly arrest development earlier, during the first larval stage (L1), in response to starvation. "L1 arrest" (also known as "L1 diapause") occurs without morphological modification but is accompanied by increased stress resistance. Caloric restriction and periodic fasting can extend adult lifespan, and developmental models are critical to understanding how the animal is buffered from fluctuations in nutrient availability, impacting lifespan. L1 arrest provides an opportunity to study nutritional control of development. Given its relevance to aging, diabetes, obesity and cancer, interest in L1 arrest is increasing, and signaling pathways and gene regulatory mechanisms controlling arrest and recovery have been characterized. Insulin-like signaling is a critical regulator, and it is modified by and acts through microRNAs. DAF-18/PTEN, AMP-activated kinase and fatty acid biosynthesis are also involved. The nervous system, epidermis, and intestine contribute systemically to regulation of arrest, but cell-autonomous signaling likely contributes to regulation in the germline. A relatively small number of genes affecting starvation survival during L1 arrest are known, and many of them also affect adult lifespan, reflecting a common genetic basis ripe for exploration. mRNA expression is well characterized during arrest, recovery, and normal L1 development, providing a metazoan model for nutritional control of gene expression. In particular, post-recruitment regulation of RNA polymerase II is under nutritional control, potentially contributing to a rapid and coordinated response to feeding. The phenomenology of L1 arrest will be reviewed, as well as regulation of developmental arrest and starvation survival by various signaling pathways and gene regulatory

    Background Childhood is a time of active growth in terms of physical size, mental, emotional and psychological development. Normal growth is dependent on adequate nutrition and encompasses major transformations from birth to adulthood. Nutrition is a focal point for health and well being; and has special significance in countries with disadvantages in socioeconomic and hygienic standards. Objective The objective of the present study was to assess the nutritional status in terms of prevalence of underweight, stunting and thinness among rural school going children. Method The present study was cross-sectional study, conducted on 438 rural school going children (169 male and 259 female) with the age group 4-16 years, during the period from April 2014 to July 2014. Age was recorded in year; height and weight were measured in centimeter and kilogram respectively. BMI was calculated by using standard equation. Result The present study concluded that the nutritional status in terms of prevalence of underweight, stunting and thinness were found to be 30.85%, 24.54% and 10.05% respectively among rural school going children of Kavre district. It was revealed that 37.87% was underweight, 29.59% was stunted and 11.25% was thinness among male children whereas in female children, 26.27% was underweight, 21.24% was stunted and 9.27% was thinness. Hence, high prevalence of underweight, stunting and thinness were observed in male than in female children. Conclusion The present study has successfully documented the nutritional status in terms of prevalence of underweight, stunting and thinness among the rural school going children of Kavre district. The results of the present study will be useful for policy makers in their endeavor to formulate various developmental and health care programs.

    Limited information is available on effects of growth hormone transgene and nutrition on growth and development of aquatic animals. Here, we present a study to test these effects with growth-enhanced transgenic common carp under two nutritional conditions or feeding rations (i.e., 5% and 10% of fish body weight per day). Compared with the nontransgenic fish, the growth rates of the transgenic fish increased significantly in both feeding rations. The shape of the pharyngeal bone was similar among treatments, but the transgenic fish had relatively smaller and lighter pharyngeal bone compared with the nontransgenic fish. Calcium content of the pharyngeal bone of the transgenic fish was significantly lower than that of the nontransgenic fish. Feeding ration also affected growth rate but less of an effect on bone development. By manipulating intrinsic growth and controlling for both environment (e.g., feeding ration) and genetic background or genotype (e.g., transgenic or not), this study provides empirical evidence that the genotype has a stronger effect than the environment on pharyngeal bone development. The pharyngeal bone strength could be reduced by decreased calcium content and calcification in the transgenic carp.

    Objectives To investigate the impact of implant-prosthetic rehabilitation combined with nutritional counseling on the nutritional status of patients with severely reduced dentitions. Design An explorative intervention study including an intra-individual comparison of 20 patients with severely reduced dentitions in terms of nutrition- and quality of life-related parameters recorded at baseline and at six and twelve months after implant-prosthetic rehabilitation. Participants Twenty patients from the Department of Prosthetic Dentistry of Justus-Liebig University of Giessen, with an mean age of 63 years, who had fewer than ten pairs of antagonists. Measurements The baseline data collection included dental status, a chewing ability test, laboratory parameters, anthropometric data (body mass index), energy supply, a 3-day dietary record, an analysis of the oral health-related quality of life (OHRQoL) with the OHIP-G14, the Mini-Mental Status (MMS) and Mini Nutritional Assessment (MNA). Six months after implantation and prosthetic rehabilitation, individual nutritional counseling was performed by a dietician. Data were again collected and analyzed. A final follow-up was conducted 12 months after prosthetic rehabilitation. Results Despite the highly significant improvement in masticatory ability and OHRQoL after implant-prosthetic rehabilitation, no significant changes were observed regarding MNA, anthropometric data or energy supply. Except for cholinesterase (p = 0.012), ferritin (p = 0.003), folic acid (p = 0.019) and vitamin A (p = 0.004), no laboratory parameter changed significantly during the investigation period. In addition, no general significant differences were observed for nutrient intake or food choice. Conclusion The present study does not confirm the assumption that the implant-prosthetic rehabilitation of patients with severely reduced residual dentitions with or without an individual nutritional counseling influences nutritional status.

    This exploratory study employed a netnographic approach (netnography being a research methodology that adopts the practices of ethnography in an Internet-based setting) to reveal opportunities for kindergarten food familiarization. The study analyses kindergarten teachers' discussions on seven Internet message boards regarding the various food and nutrition experiences in their classes. Semi-structured interviews were then conducted with seven kindergarten teachers to explore further the message board findings. Five opportunities for how food familiarization occurs in kindergartens emerged from the analysis. These opportunities were categorized as being either "overt": (1) nutrition lessons, (2) snack times, (3) cooking experiences, or "covert" (4) food as teaching materials, and (5) dramatic play centres. Overt refers to any opportunity centred on food, healthy eating, or nutrition, whereas covert refers to opportunities where food was involved but in a non-exclusive manner. The five opportunities are examined and discussed in terms of their implications for children's food preference development. Results should be useful for future researchers for two main reasons. First, the results demonstrate the wide variety of food and nutrition experiences kindergarten students encounter throughout the day, beyond healthy eating interventions or foods served during meals. And second, because the findings are preliminary they require further research using various methods of data collection and samples of teachers.

    Retinocollicular connections form precise topographical maps that are normally completed through the selective elimination of misplaced axons and the stabilization of topographically ordered axon terminals during early development. Omega-3 fatty acids, acquired exclusively through the diet, and its main metabolite, docosahexaenoic acid (DHA), are involved in brain development and synaptic maturation. We have previously shown that the nutritional restriction of omega-3/DHA results in abnormal retinocollicular topographical fine-tuning. Therefore, we studied the role of omega-3 fatty acids nutritional supplementation and the developmental time windows during which this postnatal supplementation would restore normal topographical maps in the visual system. Female rats and their litters were chronically fed with either control (soy oil) or restricted omega-3 (coconut oil) diets. Fish oil supplementation was introduced between either postnatal day (PND) 7-13, PND7-28 or PND21-42. At PND13, PND28 or PND42, animals received an anterograde eye injection of a neuronal tracer to visualize retinocollicular axons. Confirming previous observations we found that an omega-3/DHA deficiency resulted in an abnormally high innervation density of retinal axons at the visual layers of the superior colliculus (SC). Although a short-term fish oil supplementation between PND7-13 could not restore normal retinocollicular topography, an extended treatment between PND7-28 completely recovered normal innervation densities of retinotectal axons. However, a late onset supplementation protocol, between PND28-42, was no longer effective in the restoration of the abnormal topographical pattern induced by an early omega-3 nutritional malnutrition. The results suggest a critical period for omega3/DHA dietary intake for the proper development of visual topographical maps. PMID:25916576

    Holstein bull calves often reach artificial insemination centers in suboptimal body condition. Early-life nutrition is reported to increase reproductive performance in beef bulls. The objective was to determine whether early-life nutrition in Holstein bulls had effects similar to those reported in beef bulls. Twenty-six Holstein bull calves were randomly allocated into 3 groups at approximately 1 wk of age to receive a low-, medium-, or high-nutrition diet, based on levels of energy and protein, from 2 to 31 wk of age. Calves were on their respective diets until 31 wk of age, after which they were all fed a medium-nutrition diet. To evaluate secretion profiles and concentrations of blood hormones, a subset of bulls was subjected to intensive blood sampling every 4 wk from 11 to 31 wk of age. Testes of all bulls were measured once a month; once scrotal circumference reached 26cm, semen collection was attempted (by electroejaculation) every 2 wk to confirm puberty. Bulls were maintained until approximately 72 wk of age and then slaughtered at a local abattoir. Testes were recovered and weighed. Bulls fed the high-nutrition diet were younger at puberty (high=324.3 d, low=369.3 d) and had larger testes for the entire experimental period than bulls fed the low-nutrition diet. Bulls fed the high-nutrition diet also had an earlier and more substantial early rise in LH than those fed the low-nutrition diet and had increased concentrations of insulin-like growth factor-I (IGF-I) earlier than the bulls fed the low-nutrition diet. Furthermore, we detected a temporal association between increased IGF-I concentrations and an early LH rise in bulls fed the high-nutrition diet. Therefore, we inferred that IGF-I had a role in regulating the early gonadotropin rise (in particular, LH) and thus reproductive development of Holstein bulls. Overall, these results support our hypothesis that Holstein bull calves fed a high-nutrition diet reach puberty earlier and have larger testes than

    Introduction: Nutritional support generates complications that must be detected and treated on time. Objective: To estimate the incidence of some complications of nutritional support in patients admitted to general hospital wards who received nutritional support in six high-complexity institutions. Methods: Prospective, descriptive and multicentric study in patients with nutritional support; the variables studied were medical diagnosis, nutritional condition, nutritional support duration, approach, kind of formula, and eight complications. Results: A total of 277 patients were evaluated; 83% received enteral nutrition and 17% received parenteral nutrition. Some 69.3% presented risk of malnourishment or severe malnourishment at admittance. About 35.4% of those receiving enteral nutrition and 39.6% of the ones who received parenteral nutrition had complications; no significant difference per support was found (p= 0.363). For the enteral nutrition, the most significant complication was the removal of the catheter (14%), followed by diarrhea (8.3%); an association between the duration of the enteral support with diarrhea, constipation and removal of the catheter was found (p < 0.05). For parenteral nutrition, hyperglycemia was the complication of highest incidence (22.9%), followed by hypophosphatemia (12.5%); all complications were associated with the duration of the support (p < 0.05). Nutritional support was suspended in 24.2% of the patients. Conclusions: Complications with nutritional support in hospital-ward patients were frequent, with the removal of the catheter and hyperglycemia showing the highest incidence. Duration of the support was the variable that revealed an association with complications. Strict application of protocols could decrease the risk for complications and boost nutritional support benefits. PMID:24893056

    Traumatic brain injury (TBI) is a major cause of death and disability worldwide. Certain patients appear to benefit when they receive immune enhancing additives, such as glutamine, arginine, and omega-3 fatty acids. We hypothesized that TBI patients given enteral feedings containing these supplements may have improved nutrition measures and infection rates when compared to standard tube feedings. This is a retrospective review of patients from a Level-One trauma center from July 2009 to July 2013. A total of 240 TBI patients received either an immune enhancing nutrition (IEN) formula (n = 126), or a standard formula (SF) (n = 114) based on the attending surgeon's preference. Data collected included demographic information, infection information and outcome measures. Patients were similar in terms of age, ISS, head AIS, and initial prealbumin level. Patients receiving IEN were found to have lower rates of blood stream infections (10.3% vs 19.3%, p < 0.05), whereas pneumonia and UTI rates were similar between groups. In addition, both groups had similar rates of all-cause mortality and hospital length of stay, however IEN patients spent longer in the ICU and on ventilators. In TBI patients receiving IEN, prealbumin levels were higher at the second, third, and fourth week of admission (week 2 - 22.2 vs 17.4, p = 0.006; week 3 - 24.6 vs 20.1, p = 0.04; week 4 - 26.3 vs 22.1, p = 0.19; week 5 - 25.8 vs 20.3, p = 0.21). This study suggests that patients with traumatic brain injury who receive IEN are more likely to have increased prealbumin levels perhaps reflecting improved nutrition throughout their hospital stay and may show some benefit in rates of infections, particularly in bacteremia.

    Functional near infrared spectroscopy (NIRS) is a non-invasive optical imaging technique used to monitor cerebral blood flow (CBF) and by proxy neuronal activation. The use of NIRS in nutritional intervention studies is a relatively novel application of this technique, with only a small, but growing, number of trials published to date. These trials—in which the effects on CBF following administration of dietary components such as caffeine, polyphenols and omega-3 polyunsaturated fatty acids are assessed—have successfully demonstrated NIRS as a sensitive measure of change in hemodynamic response during cognitive tasks in both acute and chronic treatment intervention paradigms. The existent research in this area has been limited by the constraints of the technique itself however advancements in the measurement technology, paired with studies endeavoring increased sophistication in number and locations of channels over the head should render the use of NIRS in nutritional interventions particularly valuable in advancing our understanding of the effects of nutrients and dietary components on the brain.

    The growth and development of the human skeleton requires an adequate supply of many different nutritional factors. Classical nutrient deficiencies are associated with stunting (e.g. energy, protein, Zn), rickets (e.g. vitamin D) and other bone abnormalities (e.g. Cu, Zn, vitamin C). In recent years there has been interest in the role nutrition may play in bone growth at intakes above those required to prevent classical deficiencies, particularly in relation to optimising peak bone mass and minimising osteoporosis risk. There is evidence to suggest that peak bone mass and later fracture risk are influenced by the pattern of growth in childhood and by nutritional exposures in utero, in infancy and during childhood and adolescence. Of the individual nutrients, particular attention has been paid to Ca, vitamin D, protein and P. There has also been interest in several food groups, particularly dairy products, fruit and vegetables and foods contributing to acid–base balance. However, it is not possible at the present time to define dietary reference values using bone health as a criterion, and the question of what type of diet constitutes the best support for optimal bone growth and development remains open. Prudent recommendations (Department of Health, 1998; World Health Organization/Food and Agriculture Organization, 2003) are the same as those for adults, i.e. to consume a Ca intake close to the reference nutrient intake, optimise vitamin D status through adequate summer sunshine exposure (and diet supplementation where appropriate), be physically active, have a body weight in the healthy range, restrict salt intake and consume plenty of fruit and vegetables.

    The neonatal pig ranks among the most prominent research models for the study of pediatric nutrition and metabolism. Its precocial development at birth affords ready adaptation to artificial rearing systems, and research using this model spans a wide array of nutrients. Sophisticated in vitro and in vivo methodologies supporting both invasive, reduction-science research as well as whole-animal preclinical investigations have been developed. Potential applications may dually benefit both agricultural and medical sciences (e.g., "agrimedical research"). The broad scope of this review is to outline the fundamental elements of the piglet model and to highlight key aspects of relevance to various macronutrients, including lipids, carbohydrates, proteins/amino acids, and calcium/phosphorus. The review examines similarities between piglets and infants and also piglet idiosyncrasies, concluding that, overall, the piglet represents an adaptable and robust model for pediatric nutrition and metabolism research.

    Early-life programming is becoming an established concept that states that the environment during early development affects health and disease in adulthood, probably via epigenetic mechanisms such as DNA methylation, histone modifications, RNA silencing, or a combination. Accumulating evidence suggests that nutrition during pregnancy and early postnatal life is one of the most important environmental cues that programs microbiological, metabolic, and immunologic development. The neonatal period is crucial for the early microbial colonization of the almost sterile gastrointestinal tract of the newborn infant. These first colonizers play an important role in host health because they are involved in nutritional, immunologic, and physiologic functions. Evidence from animal and human studies indicates that the composition of the gut microbiota has an effect on body composition, digestion, and metabolic homeostasis. Furthermore, the functionality of the metabolism develops after birth when the newborn is first exposed to nutrition via the gastrointestinal tract. Exposure to environmental microbial components is also suggested to have a key role in the maturation process of the immune system, and in turn the immune system shapes the composition of the microbiota. Therefore, the use of nutritional strategies to program the microbiota composition to favor a more beneficial bacterial population and to support the development of the metabolic and immune systems may provide a good opportunity to prevent later health problems such as obesity, diabetes, and allergy.

    analyses also suggest that the physiological and developmental processes occurring in well-fed bees are vastly different than those occurring in pollen deprived bees. Our data support the hypothesis that poor diet causes normal age-related development to go awry. Conclusion Poor nutrition has major consequences for the expression of genes underlying the physiology and age-related development of nurse worker bees. More work is certainly needed to fully understand the consequences of starvation and the complex biology of nutrition and development in this system, but the genes identified in the present study provide a starting point for understanding the consequences of poor diet and for mitigating the economic costs of colony starvation.

    The impact of nutrition on brain development in preterm infants has been increasingly appreciated. Early postnatal growth and nutrient intake have been demonstrated to influence brain growth and maturation with subsequent effects on neurodevelopment that persist into childhood and adolescence. Nutrition could also potentially protect against injury. Inflammation and perinatal infection play a crucial role in the pathogenesis of white matter injury, the most common pattern of brain injury in preterm infants. Therefore, nutritional components with immunomodulatory and/or anti-inflammatory effects may serve as neuroprotective agents. Moreover, growing evidence supports the existence of a microbiome-gut-brain axis. The microbiome is thought to interact with the brain through immunological, endocrine, and neural pathways. Consequently, nutritional components that may influence gut microbiota may also exert beneficial effects on the developing brain. Based on these properties, probiotics, prebiotic oligosaccharides, and certain amino acids are potential candidates for neuroprotection. In addition, the amino acid glutamine has been associated with a decrease in infectious morbidity in preterm infants. In conclusion, early postnatal nutrition is of major importance for brain growth and maturation. Additionally, certain nutritional components might play a neuroprotective role against white matter injury, through modulation of inflammation and infection, and may influence the microbiome-gut-brain axis.

    In metazoans, members of the insulin-like peptide (ILP) family play a role in multiple physiological functions in response to the nutritional status. ILPs have been identified and characterized in a wide variety of insect species. Insect ILPs that are mainly produced by several pairs of medial neurosecretory cells in the brain circulate in the hemolymph and act systemically on target tissues. Physiological and biochemical studies in Lepidoptera and genetic studies in the fruit fly have greatly expanded our knowledge of the physiological functions of ILPs. Here, we outline the recent progress of the structural classification of insect ILPs and overview recent studies that have elucidated the physiological functions of insect ILPs involved in nutrient-dependent growth during development.

    The HEALTHY study was a randomized, controlled, multicenter and middle school-based, multifaceted intervention designed to reduce risk factors for the development of type 2 diabetes. The study randomized 42 middle schools to intervention or control, and followed students from the sixth to the eighth grades. Here we describe the design of the HEALTHY nutrition intervention component that was developed to modify the total school food environment, defined to include the following: federal breakfast, lunch, after school snack and supper programs; a la carte venues, including snack bars and school stores; vending machines; fundraisers; and classroom parties and celebrations. Study staff implemented the intervention using core and toolbox strategies to achieve and maintain the following five intervention goals: (1) lower the average fat content of foods, (2) increase the availability and variety of fruits and vegetables, (3) limit the portion sizes and energy content of dessert and snack foods, (4) eliminate whole and 2% milk and all added sugar beverages, with the exception of low fat or nonfat flavored milk, and limit 100% fruit juice to breakfast in small portions and (5) increase the availability of higher fiber grain-based foods and legumes. Other nutrition intervention component elements were taste tests, cafeteria enhancements, cafeteria line messages and other messages about healthy eating, cafeteria learning laboratory (CLL) activities, twice-yearly training of food service staff, weekly meetings with food service managers, incentives for food service departments, and twice yearly local meetings and three national summits with district food service directors. Strengths of the intervention design were the integration of nutrition with the other HEALTHY intervention components (physical education, behavior change and communications), and the collaboration and rapport between the nutrition intervention study staff members and food service personnel at both school

    Autism is a neurodevelopmental disability that may affect nutritional management of children with autism. This study aimed to compare the nutritional status of children with autism with that of typically developing children (aged 4-6 years) in China. Nutritional status was assessed by means of nutritional data, anthropometric data, biochemical assessment, physical examination for nutrient deficiencies and providing a questionnaire to parents. A total of fifty-three children with autism and fifty-three typically developing children were enrolled in this study. The parents were asked to complete the questionnaire regarding the eating behaviour and gastrointestinal symptoms of their children. They were also asked to provide a 3 d food diary. Children with autism exhibited several abnormalities in terms of eating behaviour and gastrointestinal symptoms. The levels of vitamins A and B6, Zn and Ca intakes were <80 % of the dietary reference intakes in both groups. In addition, the proportions of vitamin C and Ca intake deficiencies in the autism group were significantly higher than those in the control group. Serum Zn level was less than the normal reference range in both the groups. Serum Ca, vitamin A and folate levels in children with autism were significantly lower when compared with children without autism. According to the anthropometric data, the mean BMI, weight-for-height Z-score (Z WH) and BMI for age Z-score (Z BMIA) of children with autism were significantly higher than those of the typically developing children. Thus, nutritional inadequacies were observed in children with autism and typically developing children in China, which were, however, more pronounced among children with autism.

    Unlike five other strains of Mucor rouxii previously studied, certain nutritional factors must be present for rapid growth and completely yeastlike development of M. rouxii (National Regional Research Laboratory 1894) under CO2; high CO2 tensions markedly inhibit growth of this strain. Addition of yeast extract, peptone, or enzymatically hydrolyzed casein in substrate amounts to a basal medium (containing acid-hydrolyzed casein) completely relieved CO2 inhibition of growth and permitted yeastlike development. The “CO2 growth factor” activity of these supplements proved to be dialyzable and acid labile. These findings, together with the results of gel filtration and amino acid analysis, suggested that CO2 growth factor activity can be attributed to small peptides. Images PMID:5413828

    Nutrient deficiencies are prevalent worldwide. Diseases and morbid conditions have been described to result from nutritional deficiencies. It is essential to address nutrient deficiencies as these may lead to chronic long-term health problems such as rickets, iron deficiency anemia, goiter, obesity, coronary heart disease, type 2 diabetes, stroke, cancer and osteoporosis. In the present review we surveyed the extent and severity of nutritional deficiencies in Israel through a selective and comprehensive Medline review of previous reports and studies performed during the last 40 years. Israeli populations have multiple nutritional deficiencies, including iron, calcium, zinc, folic acid, and vitamins B12, C, D and E, spanning all age groups, several minorities, and specific regions. In Israel, some of the nutrients are mandatorily implemented and many of them are implemented voluntarily by local industries. We suggest ways to prevent and treat the nutritional deficiencies, as a step to promote food fortification in Israel. PMID:24868510

    During the last decade, the area of biotech crops modified for agronomic input traits (e.g., herbicide tolerance and insect protection) has increased to 90 million halyear, grown by over 8 million farmers in a total of 17 countries. As adoption of these improved agronomic trait biotech crops has grown, so has interest in biotech crops that have improved nutritional characteristics for use as feed and food. A previous publication by the International Life Sciences Institute (ILSI) reported on the principles and concepts proposed for the nutritional and safety assessments of foods and feeds nutritionally improved through biotechnology. In this paper, the guidelines and principles recommended in the earlier publication are discussed relative to a specific case study, Lysine maize. Lysine maize is a feed ingredient with enhanced nutritional characteristics for poultry and swine and provides an alternative to the need for addition of supplemental lysine to some diets for these animals. The 2004 Task Force of the ILSI has also applied the concepts from that report to 4 other case studies: sweet potato enriched in provitamin A (2 examples, one using biotechnology and one using conventional breeding); Golden Rice 2; double-embryo maize; and ASP-1 enhanced protein sweet potato.

    Modifying the food environment is a promising strategy for promoting healthier eating behavior. This study aimed to evaluate nutritional and weight changes in a program that used worksite cafeterias to reduce employees’ calorie content of purchased foods and improve their macronutrient intake. Participants were randomly assigned to one of two conditions: 1) only environmental change (i.e., the introduction of 10 new low-energy-density (ED) foods and provision of labels for all foods sold at lunch, which listed ED, calories, and macronutrient content) or 2) the environmental change plus pricing incentives for purchasing low-ED foods and education about low-ED eating delivered in four, 1-hour group sessions. Participant lunch choices were monitored electronically at the point of purchase for 3 months before the intervention was instituted (i.e., the baseline period) and for 3 months afterward (i.e., intervention period). Participants were adults (n = 96, BMI = 29.7 ± 6.0 kg/m2) who regularly ate lunch at their workplace cafeteria. There was no difference between groups in total energy intake over the study period. Across groups, energy and percent of energy from fat decreased and percent of energy from carbohydrate increased from baseline to the intervention period (all p <. 01). Follow-up analyses, conducted by averaging Baseline Months 1 and 2 and comparing them to Intervention Month 3 as a conservative estimate of overall impact of the intervention, indicated that change in energy, carbohydrate, and fat intake remained significant (p < .001). Providing nutrition labels and reducing the ED of selected foods was associated with improved dietary intake. PMID:20434060

    Actually, food, diet and diet therapy germinated together with the change of meal patterns and traditional Chinese medicine from very ancient China; they appeared in an embryonic form till the Shang and Zhou Dynasties and received great importance from the governors who arranged officials to manage their diets and banquets. Moreover, food, diet and meal patterns were replenished through the Zhou, Qin, Han and Jin Dynasties and epitomized and reached thriving and prosperous standards till the Tang Dynasty. They then became perfected, developed, and formed a complete theory in the dynasties of Song, Jin, Yuan, Ming and Qing. The basis of modern nutrition was made up until the end of 19th century and the beginning of 20th century, which was the time when natural science, including microbiology, chemistry, food industry, etc. were extended into China, yet it was not fully formed until the established of the People's Republic of China. Practicing, teaching, training and research activities started regularly in 1950. With a big population and poor economy basis, the first problem that the Chinese people has now been basically solved. Chinese nutritional scientists worked hard to find out the nutritional problems and status of the people. Through the broad-scale 'Nationwide Nutrition Survey', we now understand our main problems. On this basis, RDA, dietary goal and dietary guidance have been put forward. Although the problem of adequate food and clothing has been basically solved, the Chinese are still facing both the problem of nutrition insufficiency and nutrition excess. However, although nutrition insufficiency and deficiency still extensively exist, nutrition excess and imbalance are emerging in other sections of the population. There is still a shortage of qualified nutritional scientists and technicians, and the training of nutritionists is urgent. Food supplies, including milk, beef, green vegetables and fruit should be increased, especially for some rural and

  6. A randomized trial to investigate the effects of pre-natal and infant nutritional supplementation on infant immune development in rural Gambia: the ENID trial: Early Nutrition and Immune Development

    PubMed Central

    2012-01-01

    Background Recent observational research indicates that immune development may be programmed by nutritional exposures early in life. Such findings require replication from trials specifically designed to assess the impact of nutritional intervention during pregnancy on infant immune development. The current trial seeks to establish: (a) which combination of protein-energy (PE) and multiple-micronutrient (MMN) supplements would be most effective; and (b) the most critical periods for intervention in pregnancy and infancy, for optimal immune development in infancy. Methods/Design The ENID Trial is a 2 x 2 x 2 factorial randomized, partially blind trial to assess whether nutritional supplementation to pregnant women (from < 20 weeks gestation to term) and their infants (from 6 to 12 months of age) can enhance infant immune development. Eligible pregnant women from the West Kiang region of The Gambia (pregnancy dated by ultrasound examination) are randomized on entry to 4 intervention groups (Iron-folate (FeFol = standard care), multiple micronutrients (MMN), protein-energy (PE), PE + MMN). Women are visited at home weekly for supplement administration and morbidity assessment and seen at MRC Keneba at 20 and 30 weeks gestation for a detailed antenatal examination, including ultrasound. At delivery, cord blood and placental samples are collected, with detailed infant anthropometry collected within 72 hours. Infants are visited weekly thereafter for a morbidity questionnaire. From 6 to 12 months of age, infants are further randomized to a lipid-based nutritional supplement, with or without additional MMN. The primary outcome measures of this study are thymic development during infancy, and antibody response to vaccination. Measures of cellular markers of immunity will be made in a selected sub-cohort. Subsidiary studies to the main trial will additionally assess the impact of supplementation on infant growth and development to 24 months of age. Discussion

    Strategic translational research is designed to address research gaps that answer specific guidance questions. It provides translational value with respect to nutrition guidance and regulatory and public policy. The relevance and the quality of evidence both matter in translational research. For example, design decisions regarding population, intervention, comparator, and outcome criteria affect whether or not high-quality studies are considered relevant to specific guidance questions and are therefore included as evidence within the context of systematic review frameworks used by authoritative food and health organizations. The process used in systematic reviews, developed by the USDA for its Nutrition Evidence Library, is described. An eating pattern and cardiovascular disease (CVD) evidence review is provided as an example, and factors that differentiated the studies considered relevant and included in that evidence base from those that were excluded are noted. Case studies on ω-3 (n-3) fatty acids (FAs) and industrial trans-FAs illustrate key factors vital to relevance and translational impact, including choice of a relevant population (e.g., healthy, at risk, or diseased subjects; general population or high-performance soldiers); dose and form of the intervention (e.g., food or supplement); use of relevant comparators (e.g., technically feasible and realistic); and measures for both exposure and outcomes (e.g., inflammatory markers or CVD endpoints). Specific recommendations are provided to help increase the impact of nutrition research on future dietary guidance, policy, and regulatory issues, particularly in the area of lipids. PMID:27422509

    Previous reviews of nutritional status in children under 5 years describe the Caribbean grouped with Latin America. This paper focuses specifically on the Caribbean and the goals and targets of the Millennium Declaration that have bearing on childhood development. The results indicate that CARICOM countries have made progress in terms of child health as assessed by gross health indicators. Yet, the millennium generation experiences coexistence of undernutrition and overweight in early childhood. The associations of GNI with markers such as poverty indices are somewhat inconsistent with traditional findings and highlight a need to reassess the causes of infant mortality and low birth weight. However, a lack of systematic local data has hampered progress on an individual country basis. Interventions that deal more pointedly with country specific needs are required including those targeting obesity if the MDGs are to be attained by all member states.

    Pregnancy is a vital period where several hyperplasic, hypertrophic processes together with metabolic adaptation and preparation for extra-uterine life take place. Present review accounts for central aspects of nutrition throughout gestation on the embryonic and fetal periods. It is centered in the major changes occurring in fetal pancreas, with special mention to the susceptibility of this main glucose homeostasis organ to support nutritional changes during maturation and development. Studies performed in animal models as human are commented considering the role of maternal nutrition on β-cell mass size, insulin and other pancreatic hormones production, and insulin sensitivity. Details of both the thrifty genotype and phenotype hypothesis are given, indicating that hypo/subnutrition causes metabolic adaptations that permit the future body to grow and develop itself in limited environmental and energetic conditions. The Barker hypothesis is considered suggesting that this metabolic hypothesis is a double-edged sword in the actual abundance World. Lastly the review, taking into account our own research and other papers, analyses less known aspects that relate maternal diet with insulin resistance/sensitivity markers at delivery. Particularly the role of the saturated fatty acid/carbohydrate and omega-6/omega-3 ratios in the frame of maternal diet is reviewed considering the quality of those diets under the Healthy Eating Index and the Adherence to Mediterranean Diet scores and the relationship with insulin resistance profile at birth. Present review ends indicating that nutritional habits should be strongly stated before gestation in order to assure a proper nutrition since the first moment of pregnancy. This will support an adequate fetal and pancreatic growth and development, and in turn, adequate glucose homeostasis during pregnancy and later in life, slowing down or preventing from degenerative diseases related with metabolic syndrome and type 2 diabetes

    Malpighiaceae ovules have a well-developed nucellus; previous observations indicate that during seed development, the endosperm does not proliferate, thus, remaining scarce. This study aimed at identifying the nutritive tissues during seed development in Malpighiaceae, focusing especially on the endosperm. We analysed the seed development of Janusia mediterranea, J. occhionii, Mascagnia cordifolia, and Tetrapterys chamaecerasifolia, which were collected and processed by traditional methods for light microscopy. Ovules are subcampylotropous, crassinucellate and unitegmic in Janusia and bitegmic in M. cordifolia and T. chamaecerasifolia. The nucellus is well developed and protrudes through the micropyle, touching the funicular obturator. During development, a pachychalaza is formed, and the integuments coalesce in bitegmic species. Through a series of nucellar cell divisions, the perisperm is formed. In Janusia species, the endosperm is not produced. In M. cordifolia and T. chamaecerasifolia, the endosperm is nuclear, but it is scarce and ephemeral. The mature seed is exalbuminous, and the perisperm is consumed, and thus, the mature embryo is total. The absence of endosperm in Janusia is newly observed for the family and indicates functional transfer for the abundant perisperm.

    The purpose of this study was to investigate the nutrition and diet related knowledge, attitude, and behavior of elementary school children in Seoul. The subjects included were 439 (male 236, female 203) elementary school children in the 4th to the 6th grades. The statistical analysis was conducted using SPSS 12.0 program. The average obesity index (OI) was 104.98 and 99.82 for male and female subjects, respectively. The average percentage of underweight, normal, overweight and obese of subjects was 33.7%, 32.8%, 12.3%, and 19.4%, respectively. The percentage of the underweight group of female subjects was higher than that of the male subjects. The percentage of the obese group of male subjects was higher than that of the female subjects. The average score of nutrition knowledge, nutrition attitude and dietary behavior was 6.8, 7.44, and 7.34, respectively. Dietary behavior of male subjects was positively correlated with parents' education levels, monthly household income and nutrition attitude. Dietary behavior of female subjects was positively correlated with monthly household income, nutrition knowledge and nutrition attitude. Dietary behavior of female subjects was positively correlated with obesity index (OI). Proper nutrition education and intervention are required for the improvement of elementary school children's nutrition knowledge, nutrition attitudes and dietary behaviors. PMID:20016735

    Nutritional and developmental insults in the first few years of life have profound public health implications, including substantial contributions to neonatal, infant, and early childhood morbidity and mortality, as well as longer term impacts on cognitive development, school achievement, and worker productivity. Optimal development that can lead to the attainment of the individual's fullest potential therefore requires a combination of genetic capacity, adequate nutrition, psychosocial stimulation, and safe, clean physical environments. Researchers and policymakers have called for integrated child nutrition and development interventions for more than twenty years, yet there are only a handful of efficacy trials and even fewer examples of integrated interventions that have been taken to scale. While a critical component to the design of such interventions is formative research, there is a dearth of information in both the literature and policy arenas to guide this phase of the process. To move the field forward, this paper first provides an overview of formative research methods with a focus on qualitative inquiry, a description of the critical domains to be assessed (infant and young child feeding, responsive feeding, and child development), and currently available resources. Application of these methods is provided through a real-world case study—the design of an integrated nutrition and child development efficacy trial in Andhra Pradesh, India. Recommendations for next steps are discussed, the most important of which is the need for a comprehensive set of formative guidelines for designing locally tailored, culturally appropriate integrated interventions.

    This article describes the development and field testing of five 1-minute videotaped nutrition public service announcements focusing on the role of nutrition in reducing cancer risks. Topics include dietary fat, vitamin A, vitamin C, cruciferous vegetables, and fiber. Produce departments in two large supermarkets were the test sites. Videotapes were shown over a 3-day period for a total of 20 hours in each store. Of the total 1,196 customers intercepted, 1,050 (88 percent) agreed to be interviewed to determine whether they had viewed the video; the impact of the video on nutrition awareness, diet, and immediate purchases; and their perception of the stores' providing nutrition information. Only 26 percent of the customers viewed the videotapes. The main reason cited for nonviewing was lack of time. Forty-three percent of viewers stated that this was new information to them, and 21 percent said they would change their eating habits as a result of seeing the tape. Seventeen percent of viewers stated that they actually purchased foods recommended in the tapes. Of all the customers surveyed, 40 percent said they would shop more often at a supermarket that showed nutrition videos. PMID:1333620

  1. Choline nutrition programs brain development via DNA and histone methylation.

    PubMed

    Blusztajn, Jan Krzysztof; Mellott, Tiffany J

    2012-06-01

    Choline is an essential nutrient for humans. Metabolically choline is used for the synthesis of membrane phospholipids (e.g. phosphatidylcholine), as a precursor of the neurotransmitter acetylcholine, and, following oxidation to betaine, choline functions as a methyl group donor in a pathway that produces S-adenosylmethionine. As a methyl donor choline influences DNA and histone methylation--two central epigenomic processes that regulate gene expression. Because the fetus and neonate have high demands for choline, its dietary intake during pregnancy and lactation is particularly important for normal development of the offspring. Studies in rodents have shown that high choline intake during gestation improves cognitive function in adulthood and prevents memory decline associated with old age. These behavioral changes are accompanied by electrophysiological, neuroanatomical, and neurochemical changes and by altered patterns of expression of multiple cortical and hippocampal genes including those encoding key proteins that contribute to the biochemical mechanisms of learning and memory. These actions of choline are observed long after the exposure to the nutrient ended (months) and correlate with fetal hepatic and cerebral cortical choline-evoked changes in global- and gene-specific DNA cytosine methylation and with dramatic changes of the methylation pattern of lysine residues 4, 9 and 27 of histone H3. Moreover, gestational choline modulates the expression of DNA (Dnmt1, Dnmt3a) and histone (G9a/Ehmt2/Kmt1c, Suv39h1/Kmt1a) methyltransferases. In addition to the central role of DNA and histone methylation in brain development, these processes are highly dynamic in adult brain, modulate the expression of genes critical for synaptic plasticity, and are involved in mechanisms of learning and memory. A recent study documented that in a cohort of normal elderly people, verbal and visual memory function correlated positively with the amount of dietary choline consumption

    Focus group interviews were used to develop a nutrition education video and a teacher's guide for use in Florida high schools. Authors conducted a pilot and four focus group interviews with ninth grade students in five geographically distinct regions of Florida. Most students agreed that a video with scenarios or success stories would work well. Teens expressed interest in 10 topics: eating disorders; consequences of unhealthy eating; preparing quick, healthy meals; what constitutes a balanced diet; nutrition and fitness; weight control; food and the environment; the food guide pyramid; nutrition facts and fallacies; and food labels. Students suggested no more than three or four topics should be covered in the video, and the video cast should consist mainly of teen-agers with different body sizes, who were average, attractive, and from different ethnic backgrounds. Music was recommended only for transitions between scenes, as background, or during the credits. PMID:9471089

    Knowledge of reproductive biology of plants is crucial to understand their natural mode of propagation, which may aid in conservation and crop improvement. The reproductive details are also crucial for beginning the cultivation of a potential crop on a commercial scale. Fruits of sea buckthorn, Hippophae rhamnoides, are used in a variety of medicinal and nutritional products. So far, fruits are collected from the female plants in the wild. It is known that the species fruits profusely and also propagates by forming root suckers, but the details of sexual reproduction are not available. We investigated the mode of reproduction and development of fruits from natural populations of sea buckthorn. Megasporogenesis and megagametogenesis were studied through resin-embedded sectioning and ovule-clearing methods, and fruit development through histochemistry. The study of mitosis and male meiosis showed that the plants at the site were diploid (2n = 2x = 24). The embryo sac may develop either through the monosporic pathway and differentiates into 'Polygonum type' or aposporously into 'Panicum type'. The embryo may develop by sexual and adventitious pathways. Thus, sea buckthorn is a facultative apomict. The occurrence of diverse reproductive pathways assures the possibility of generation of novel genotypes through sexuality, while apomictic reproduction maintains adaptive genotypes and ensures reproduction in the absence of pollination. Anatomical details suggest that the fruit of sea buckthorn may be appropriately described as a pseudo-drupe.

    Nutrition is an important factor that regulates reproductive performance of sheep and affects follicle development. However, the correlation between nutrition and follicle development is poorly understood at the molecular level. To study its possible molecular mechanisms, we performed expression profiling of granulosa cells isolated from sheep that were fed different levels of nutrition levels during the luteal phase. To do this, ewes received a maintenance diet (M), and their estrus was synchronized by intravaginal progestogen sponges for 12 days. Ewes were randomly divided into the short-term dietary-restricted group (R; 0.5 × M) and the nutrient-supplemented group (S; 1.5 × M). RNA samples were extracted from granulosa cells. Transcriptome libraries from each group were constructed by Illumina sequencing. Among 18 468 detected genes, 170 genes were significantly differentially expressed, of which 140 genes were upregulated and 30 genes were downregulated in group S relative to group R. These genes could be candidates regulating follicular development in sheep. Gene Ontology, KEGG and clustering analyses were performed. Genes related to oocyte meiosis, such as ADCY7, were upregulated. We identified two important groups of related genes that were upregulated with improved nutrition: one group comprising the genes PTGS2, UCP2 and steroidogenic acute regulatory protein and the other group comprising interleukin-1A and interleukin-1B. The genes within each group showed similar expression patterns. Additionally, all five genes are involved in the reproduction process. Quantitative real-time PCR was performed to validate the results of expression profiling. These data in our study are an abundant genomic resource to expand the understanding of the molecular and cellular events underlying follicle development. PMID:26970339

    Pregnancy is a vital time of growth and development during which maternal nutrition significantly influences the future health of both mother and baby. During pregnancy, the fetus experiences a critical period of plasticity. Epigenetics, specifically DNA methylation, plays an important role here. As nutrition is influential for DNA methylation, this review aims to determine if maternal nutrition during pregnancy can modify the offspring's epigenome at birth. Research focuses on micronutrients and methyl donors such as folate and B vitamins. Evidence suggests that maternal nutrition does not largely influence global methylation patterns, particularly in nutrient-replete populations; however, an important impact on gene-specific methylation is observed. A link is shown between maternal nutrition and the methylome of the offspring; however, there remains a paucity of research. With the potential to use DNA methylation patterns at birth to predict health of the child in later life, it is vital that further research be carried out. PMID:26917970

    2015-01-01

    Background Tuberculosis (TB) and under-nutrition are widespread in many low and middle-income countries. Momentum to prioritize under-nutrition has been growing at an international level, as demonstrated by the "Scaling Up Nutrition" movement. Low body mass index is an important risk factor for developing TB disease. The objective of this study was to project future trends in TB related outcomes under different scenarios for reducing under-nutrition in the adult population in the Central Eastern states of India. Methods A compartmental TB transmission model stratified by body mass index was parameterized using national and regional data from India. We compared TB related mortality and incidence under several scenarios that represented a range of policies and programs designed to reduce the prevalence of under-nutrition, based on the experience and observed trends in similar countries. Results The modeled nutrition intervention scenarios brought about reductions in TB incidence and TB related mortality in the Central Eastern Indian states ranging from 43% to 71% and 40% to 68% respectively, relative to the scenario of no nutritional intervention. Modest reductions in under-nutrition averted 4.8 (95% UR 0.5, 17.1) million TB cases and 1.6 (95% UR 0.5, 5.2) million TB related deaths over a period of 20 years of intervention, relative to the scenario of no nutritional intervention. Complete elimination of under-nutrition in the Central Eastern states averted 9.4 (95% UR 1.5, 30.6) million TB cases and 3.2 (95% UR 0.7-, 10.1) million TB related deaths, relative to the scenario of no nutritional intervention. Conclusion Our study suggests that intervening on under-nutrition could have a substantial impact on TB incidence and mortality in areas with high prevalence of under-nutrition, even if only small gains in under-nutrition can be achieved. Focusing on under-nutrition may be an effective way to reduce both rates of TB and other diseases associated with under-nutrition

    Background Nutritional deficits in early life have been associated with a higher prevalence of metabolic syndrome (MetS) in adulthood. Early childhood diarrhea contributes to under-nutrition and may potentially increase the risk for adult non-communicable diseases. Our objective was to examine associations between early childhood diarrhea burden and later development of MetS. Methods We studied individuals who participated in the Institute of Nutrition of Central America and Panama Nutritional Supplementation Longitudinal Study (1969–1977) and were followed up in 2002–04. We used logistic regression to determine associations of diarrhea burden at ages 0–6 mo, 6–12 mo, and 12–24 mo with odds of MetS and elevations in its components as adults. Results Among 389 adults age 25–42 years at follow-up the prevalence of MetS was 29%. Adjusting for several confounders including adult BMI, each absolute 1% increase in diarrhea burden at age 0–6 mo (but not at other time periods) was associated with increased odds of MetS (odds ratio 1.03; 95% CI 1.01–1.06). This was attributable primarily to associations with elevated BP (OR 1.03, 1.00–1.06) and waist circumference (OR 1.03, 1.00–1.06). Conclusions Childhood diarrhea burden 0–6 months is associated with MetS in adulthood after controlling for childhood growth parameters and adult BMI. PMID:23608305

    Non-nutritive sucking (NNS) is one of the most significant spontaneous actions of infants. The suction/expression rhythmicity of NNS remains unknown. We developed a sensorized pacifier for an objective measurement of NNS. Two miniaturized digital pressure sensors are embedded into a commercial pacifier and they acquired suction and expression pressures simultaneously. Experimental tests with nine newborns confirmed that our device is suitable for the measurement of the natural NNS behavior and for the extrapolation of parameters related to the suction/expression rhythmicity. Preliminary results encourage future studies to evaluate the possibility to use these parameters as indicators of oral feeding readiness of premature infants. PMID:26738001

    The contingency scenario for an emergency cabin depressurization event may require crewmembers to subsist in a pressurized suit for up to 144 hours. This scenario requires the capability for safe nutrition delivery through a helmet feed port against a 4 psi pressure differential to enable crewmembers to maintain strength and cognition to perform critical tasks. Two nutritional delivery prototypes were developed and analyzed for compatibility with the helmet feed port interface and for operational effectiveness against the pressure differential. The bag-in-bag (BiB) prototype, designed to equalize the suit pressure with the beverage pouch and enable a crewmember to drink normally, delivered water successfully to three different subjects in suits pressurized to 4 psi. The Boa restrainer pouch, designed to provide mechanical leverage to overcome the pressure differential, did not operate sufficiently. Guidelines were developed and compiled for contingency beverages that provide macro-nutritional requirements, a minimum one-year shelf life, and compatibility with the delivery hardware. Evaluation results and food product parameters have the potential to be used to improve future prototype designs and develop complete nutritional beverages for contingency events. These feeding capabilities would have additional use on extended surface mission EVAs, where the current in-suit drinking device may be insufficient.

    Background Food-Based Dietary Guidelines (FBDGs) are developed to promote healthier eating patterns, but increasing food prices may make healthy eating less affordable. The aim of this study was to design a range of cost-minimized nutritionally adequate health-promoting food baskets (FBs) that help prevent both micronutrient inadequacy and diet-related non-communicable diseases at lowest cost. Methods Average prices for 312 foods were collected within the Greater Copenhagen area. The cost and nutrient content of five different cost-minimized FBs for a family of four were calculated per day using linear programming. The FBs were defined using five different constraints: cultural acceptability (CA), or dietary guidelines (DG), or nutrient recommendations (N), or cultural acceptability and nutrient recommendations (CAN), or dietary guidelines and nutrient recommendations (DGN). The variety and number of foods in each of the resulting five baskets was increased through limiting the relative share of individual foods. Results The one-day version of N contained only 12 foods at the minimum cost of DKK 27 (€ 3.6). The CA, DG, and DGN were about twice of this and the CAN cost ~DKK 81 (€ 10.8). The baskets with the greater variety of foods contained from 70 (CAN) to 134 (DGN) foods and cost between DKK 60 (€ 8.1, N) and DKK 125 (€ 16.8, DGN). Ensuring that the food baskets cover both dietary guidelines and nutrient recommendations doubled the cost while cultural acceptability (CAN) tripled it. Conclusion Use of linear programming facilitates the generation of low-cost food baskets that are nutritionally adequate, health promoting, and culturally acceptable. PMID:27760131

    Enterocutaneous fistula is a challenging clinical condition with serious complications and considerable morbidity and mortality. Early nutritional support has been found to decrease these complications and to improve the clinical outcome. Location of the fistula and physiological status affect the nutrition management plan in terms of feeding route, calories, and protein requirements. This study investigated the nutritional management procedures at the Universiti Kebangsaan Malaysia Medical Center, and attempted to determine factors that affect the clinical outcome. Nutritional management was evaluated retrospectively in 22 patients with enterocutaneous fistula seen over a 5-year period. Medical records were reviewed to obtain data on nutritional status, biochemical indices, and route and tolerance of feeding. Calories and protein requirements are reported and categorized. The results show that surgery was the predominant etiology and low output fistula was the major physiological category; anatomically, the majority were ileocutaneous. The spontaneous healing rate was 14%, the total healing rate was 45%, and the mortality rate was 22%, with 14% due to fistula-associated complications. There was a significant relationship between body mass index/serum albumin levels and fistula healing; these parameters also had a significant relationship with mortality. Glutamine was used in 50% of cases; however, there was no significant relationship with fistula healing or mortality rate. The nutritional status of the patient has an important impact on the clinical outcome. Conservative management that includes nutrition support is very important in order to improve nutritional status before surgical repair of the fistula.

    In New Zealand, the burden of nutrition-related disease is greatest among vulnerable and disadvantaged groups, including Maori and Pacific peoples. However, little research is currently available on effective ways to improve nutrition in these communities. This paper describes the development of six paper-based nutrition education resources for multi-ethnic participants in a large supermarket intervention trial. Six focus groups involving 15 Maori, 13 Pacific and 16 non-Maori, non-Pacific participants were held. A general inductive approach was applied to identify common themes around participants' understanding and thoughts on relevance and usefulness of the draft resources. Feedback from focus groups was used to modify resources accordingly. Five themes emerged across all focus groups and guided modification of the resources: (i) perceived higher cost of healthy food, (ii) difficulty in changing food-purchasing habits, (iii) lack of knowledge, understanding and information about healthy food, (iv) desire for personally relevant information that uses ethnically appropriate language and (v) other barriers to healthy eating, including limited availability of healthy food. Many issues affect the likelihood of purchase and consumption of healthy food. These issues should be taken into account when developing nutritional materials for New Zealanders and possibly other multi-ethnic populations worldwide.

    Intrauterine growth restriction is a significant problem worldwide, resulting in increased rates of neonatal morbidity and mortality, as well as increased risks for metabolic and cardiovascular disease. The present study investigated the role of maternal undernutrition and L-arginine administration on fetal growth and development. Embryo transfer was utilized to generate genetically similar singleton pregnancies. On Day 35 of gestation, ewes were assigned to receive either 50 or 100% of their nutritional requirements. Ewes received i.v. injections of either saline or L-arginine three times daily from Day 100 to Day 125. Fetal growth was assessed at necropsy on Day 125. Maternal dietary manipulation altered circulating concentrations of leptin, progesterone, and amino acids in maternal plasma. Fetal weight was reduced in nutrient-restricted ewes on Day 125 compared with 100% fed ewes. Compared with saline-treated underfed ewes, maternal L-arginine administration did not affect fetal weight but increased weight of the fetal pancreas by 32% and fetal peri-renal brown adipose tissue mass by 48%. These results indicate that L-arginine administration enhanced fetal pancreatic and brown adipose tissue development. The postnatal effects of increased pancreatic and brown adipose tissue growth warrant further study.

Weight proportions of mean moisture, ash, protein, and lipid contents of the minced fish were 75.49, 1.00, 15.00, and 7.92 (g/100 g), respectively. The formulation of the developed pâté is in accordance with legislation for fish products. Cachapinta pâté is a product with high content of polyunsaturated fatty acids, low level of trans fat, and good indices of nutritional quality. Tests of sensory acceptance, purchase intent, and sensory attributes (except spreadability) averaged a score above 6.0, indicating acceptability of the product. Our study suggests that the potential of minced cachapinta for pâté production is high, and that it can contribute a value-added product to seafood consumption. PMID:25649424

    Background Accumulating data from animal and human studies indicate that the prenatal environment plays a significant role in shaping children’s neurocognitive development. Clinical, epidemiologic, and basic science research suggests that two experiences relatively common in pregnancy — an unhealthy maternal diet and psychosocial distress — significantly affect children’s future neurodevelopment. These prenatal experiences exert their influence in the context of one another and yet, almost uniformly, are studied independently. Scope and Method of Review In this review, we suggest that studying neurocognitive development in children in relation to both prenatal exposures is ecologically most relevant, and methodologically most sound. To support this approach, we selectively review two research topics that demonstrate the need for dual exposure studies, including exemplar findings on (1) the associations between pregnant women’s inadequate maternal intake of key nutrients – protein, fat, iron, zinc, and choline – as well as distress in relation to overlapping effects on children’s neurocognitive development; and (2) cross-talk between the biology of stress and nutrition that can amplify each experience for the mother and fetus,. We also consider obstacles to this kind of study design, such as questions of statistical methods for ‘disentangling’ the exposure effects, and aim to provide some answers. Conclusion Studies that specifically include both exposures in their design can begin to determine the relative and/or synergistic impact of these prenatal experiences on developmental trajectories — and thereby contribute most fully to the understanding of the early origins of health and disease.

    2012-08-01

    Eating habits may be formed at a young age and once entrenched, tend to track across childhood and beyond (Tsuji et al, 2012). Although parents have a significant role in the development of their child's dietary intake (Clarke et al, 2007), Harris (2010) argues that the diets and feeding habits of young children are now no longer the sole responsibility of parents but other childcare professionals, including nannies and nursery staff. The aim of this article is to provide parents and professionals with guidance to help encourage parents, and other members of the multidisciplinary team, to provide children with a healthy diet.

    Background Maternal and child under nutrition is highly prevalent in low-income and middle-income countries, resulting in substantial increases in mortality and overall disease burden. The aim of this baseline survey was to determine the association between selected maternal characteristics, maternal nutritional status and children’s nutritional status. Methods and Findings A survey with a cross sectional design was conducted between September and October 2012 in Hula, Ethiopia. The study subjects were 197 mothers of children between the ages of 6 and 23 months. Weight and height (mothers) or recumbent length (children) were measured using calibrated, standardized techniques. Seven percent of children were below -2 weight for height Z score (WHZ), 11.5% were below -2 height for age Z score (HAZ) and 9.9% were below -2 weight for age Z score (WAZ). Maternal anthropometrics were associated with child nutritional status in the bivariate analysis. Maternal BMI (r = 0.16 P = 0.02) and educational status (r = 0.25 P = 0.001) were correlated with WHZ of children while maternal height (r = 0.2 P = 0.007) was correlated with HAZ of children. After multivariate analysis, children whose mothers had salary from employment had a better WHZ score (P = 0.001) and WAZ score (P<0.001). Both maternal BMI and maternal height were associated with WHZ (P = 0.04) and HAZ (P = 0.01) score of children. Conclusion Having a mother with better nutritional status and salaried employment is a benefit for the nutritional status of the child. The interrelationship between maternal and child nutritional status stresses the value of improving maternal nutritional status as this should improve both maternal and child health outcomes. Therefore strategies to improve nutritional status of children should also include improving the nutritional status of the mother and empowering her financially. PMID:26588687

    Long-term follow-up of randomised trials and observational studies provide the best evidence presently available to assess long-term effects of nutrition, and such studies are an important component in determining optimal infant feeding practices. Attrition is, however, an almost inevitable occurrence with increasing age at follow-up. There is a common assumption that studies with <80% follow-up rates are invalid or flawed, and this criticism seems to be more frequently applied to follow-up studies involving randomised trials than observational studies. In this article, we explore the basis and evidence for this "80% rule" and discuss the need for greater consensus and clear guidelines for analysing and reporting results in this specific situation.

    2014-01-01

    Introduction Tailoring interventions to address identified barriers to change may be an effective strategy to implement guidelines and improve practice. However, there is inadequate data to inform the optimal method or level of tailoring. Consequently, we conducted the PERFormance Enhancement of the Canadian nutrition guidelines by a Tailored Implementation Strategy (PERFECTIS) study to determine the feasibility of a multifaceted, interdisciplinary, tailored intervention aimed at improving adherence to critical care nutrition guidelines for the provision of enteral nutrition. Methods A before-after study was conducted in seven ICUs from five hospitals in North America. During a 3-month pre-implementation phase, each ICU completed a nutrition practice audit to identify guideline-practice gaps and a barriers assessment to identify obstacles to practice change. During a one day meeting, the results of the audit and barriers assessment were reviewed and used to develop a site-specific tailored action plan. The tailored action plan was then implemented over a 12-month period that included bi-monthly progress meetings. Compliance with the tailored action plan was determined by the proportion of items in the action plan that was completely implemented. We examined acceptability of the intervention through staff responses to an evaluation questionnaire. In addition, the nutrition practice audit and barriers survey were repeated at the end of the implementation phase to determine changes in barriers and nutrition practices. Results All five sites successfully completed all aspects of the study. However, their ability to fully implement all of their developed action plans varied from 14% to 75% compliance. Nurses, on average, rated the study-related activities and resources as ‘somewhat useful’ and a third of respondents ‘agreed’ or ‘strongly agreed’ that their nutrition practice had changed as a result of the intervention.

  19. Planning strategies for development of effective exercise and nutrition countermeasures for long-duration space flight

    2002-01-01

    Exercise and nutrition represent primary countermeasures used during space flight to maintain or restore maximal aerobic capacity, musculoskeletal structure, and orthostatic function. However, no single exercise, dietary regimen, or combination of prescriptions has proven entirely effective in maintaining or restoring cardiovascular and musculoskeletal functions to preflight levels after prolonged space flight. As human space flight exposures increase in duration, identification, assessment, and development of various effective exercise- and nutrition-based protective procedures will become paramount. The application of adequate dietary intake in combination with effective exercise prescription will be based on identification of basic physiologic stimuli that maintain normal function in terrestrial gravity, and understanding how specific combinations of exercise characteristics (e.g., duration, frequency, intensity, and mode) can be combined with minimal nutritional requirements that mimic the stimuli normally produced by living in Earth's gravity environment. This can be accomplished only with greater emphasis of research on ground-based experiments targeted at understanding the interactions between caloric intake and expenditure during space flight. Future strategies for application of nutrition and exercise countermeasures for long-duration space missions must be directed to minimizing crew time and the impact on life-support resources.

    2015-01-01

    Unlike the genome, the epigenome can be modified and hence some epigenetic risk markers have the potential to be reversed. Such modifications take place by means of drugs, diet or environmental exposures. It is widely accepted that epigenetic modifications take place during early embryonic and primordial cell development, but it is also important that we gain an understanding of the potential for such changes later in life. These “later life” epigenetic modifications in response to dietary intervention are the focus of this paper. The epigenetic modifications investigated include DNA methylation, histone modifications and the influence of microRNAs. The epigenotype could be used not only to predict susceptibility to certain cancers but also to assess the effectiveness of dietary modifications to reduce such risk. The influence of diet or dietary components on epigenetic modifications and the impact on cancer initiation or progression has been assessed herein. PMID:25647662

    Nutrition is a well-known factor in the growth, health and development of children. It is also acknowledged that worldwide many people have dietary imbalances resulting in over- or undernutrition. In 2009, the multinational food company FrieslandCampina initiated the South East Asian Nutrition Survey (SEANUTS), a combination of surveys carried out in Indonesia, Malaysia, Thailand and Vietnam, to get a better insight into these imbalances. The present study describes the general study design and methodology, as well as some problems and pitfalls encountered. In each of these countries, participants in the age range of 0·5-12 years were recruited according to a multistage cluster randomised or stratified random sampling methodology. Field teams took care of recruitment and data collection. For the health status of children, growth and body composition, physical activity, bone density, and development and cognition were measured. For nutrition, food intake and food habits were assessed by questionnaires, whereas in subpopulations blood and urine samples were collected to measure the biochemical status parameters of Fe, vitamins A and D, and DHA. In Thailand, the researchers additionally studied the lipid profile in blood, whereas in Indonesia iodine excretion in urine was analysed. Biochemical data were analysed in certified laboratories. Study protocols and methodology were aligned where practically possible. In December 2011, data collection was finalised. In total, 16,744 children participated in the present study. Information that will be very relevant for formulating nutritional health policies, as well as for designing innovative food and nutrition research and development programmes, has become available.

    Bedouin Arabs in southern Israel are a traditionally semi-nomadic population undergoing the nutrition transition in a context of urbanisation. The effect of these changes on the nutritional status of pregnant women is unknown. The Dietary Exposures and Pregnancy Outcomes in a Society In Transition (DEPOSIT) study evaluated the adequacy of pregnant Bedouin women's usual dietary intake and their nutritional status. Dietary intake was assessed in a cross-sectional study design using repeat 24 h recall (24HR) questionnaires. The National Cancer Institute method was used to estimate the usual intake of selected nutrients. The Estimated Average Requirement (EAR) was used to evaluate nutrient intake adequacy. Measured weight and height data were used to calculate the participants' BMI. A total of 1109 24HR were obtained from 683 participants, of which 8 % contained no animal-source protein and an additional 43 % contained no haeme-Fe. Animal-source protein intake reached less than half of the EAR for most participants (71 %). Over 90 % had inadequate intakes of Ca, Fe, animal-source Zn, vitamin A and folate. The probability of consuming haeme-source Fe was higher among urban than rural participants (OR 1·68, 95 % CI 1·17, 2·41), and among those with employed v. unemployed husbands (OR 1·81, 95 % CI 1·27, 2·58). Only 14 % reported consuming home-produced animal products. According to pre-pregnancy BMI, 42 % were overweight or obese. The DEPOSIT study findings suggest that Bedouin Arab women are in need of interventions that address the co-existing problems of inadequate nutrient intakes and increased risk of obesity.

    This review compares iron and zinc food sources, dietary intakes, dietary recommendations, nutritional status, bioavailability and interactions, with a focus on adults in economically-developed countries. The main sources of iron and zinc are cereals and meat, with fortificant iron and zinc potentially making an important contribution. Current fortification practices are concerning as there is little regulation or monitoring of intakes. In the countries included in this review, the proportion of individuals with iron intakes below recommendations was similar to the proportion of individuals with suboptimal iron status. Due to a lack of population zinc status information, similar comparisons cannot be made for zinc intakes and status. Significant data indicate that inhibitors of iron absorption include phytate, polyphenols, soy protein and calcium, and enhancers include animal tissue and ascorbic acid. It appears that of these, only phytate and soy protein also inhibit zinc absorption. Most data are derived from single-meal studies, which tend to amplify impacts on iron absorption in contrast to studies that utilize a realistic food matrix. These interactions need to be substantiated by studies that account for whole diets, however in the interim, it may be prudent for those at risk of iron deficiency to maximize absorption by reducing consumption of inhibitors and including enhancers at mealtimes.

    Parenteral nutrition (PN) is a feeding mode suitable for children that do not achieve requirements via the enteral route. For this intervention to be successful, healthcare professionals require: knowledge on nutrient requirements; access to an aseptic compounding facility; and a system that ensures adequate and safe delivery of PN. Previously, it was thought that individualised PN was the “gold standard” for delivering nutrients to children; however, studies have highlighted concerns regarding inadequate delivery of nutrients, prescribing and compounding errors. We, therefore, set out to develop and implement all-in-one (AIO) paediatric PN solutions. Through a systematic approach, four AIO PN solutions were developed: birth–two months of age (Ped 1); two months–10 kg (Ped 2); 11–15 kg (Ped 3); and 16–30 kg (Ped 4). We implemented them with the help of a teaching pack, over a one month time period, and reviewed usage at six months. At that time, five children initially received standard PN without electrolyte changes; but after a few days, electrolytes needed amendments, and three required individualised PN. A change to AIO PN is feasible and safe; however, some may require electrolyte changes, and there will always be those that will require individualised PN. PMID:23739142

    During the last 2 decades, the public and private sectors have made substantial international research progress toward improving the nutritional value of a wide range of food and feed crops. Nevertheless, significant numbers of people still suffer from the effects of undernutrition. In addition, the nutritional quality of feed is often a limiting factor in livestock production systems, particularly those in developing countries. As newly developed crops with nutritionally improved traits come closer to being available to producers and consumers, we must ensure that scientifically sound and efficient processes are used to assess the safety and nutritional quality of these crops. Such processes will facilitate deploying these crops to those world areas with large numbers of people who need them. This document describes 5 case studies of crops with improved nutritional value. These case studies examine the principles and recommendations published by the Intl. Life Sciences Inst. (ILSI) in 2004 for the safety and nutritional assessment of foods and feeds derived from nutritionally improved crops (ILSI 2004). One overarching conclusion that spans all 5 case studies is that the comparative safety assessment process is a valid approach. Such a process has been endorsed by many publications and organizations, including the 2004 ILSI publication. The type and extent of data that are appropriate for a scientifically sound comparative safety assessment are presented on a case-by-case basis in a manner that takes into account scientific results published since the 2004 ILSI report. This report will appear in the January issue of Comprehensive Reviews in Food Science and Food Safety.

    This review focuses on the nutritional effects from birth until age at first calving on growth, mammary developmental changes, and first-lactation milk yield in heifer calves. The advancement in the genetic potential and the nutritional requirements of the animals has hastened the growth rate. Genetic selection for high milk yield has suggested higher growth capacity and hence increasing nutritional inputs are required. Rapid rearing by feeding high energy or high concentrate diets not only reduces the age of sexual maturity but also lowers the time period of attaining the age of first calving. However, high energy diets may cause undesirable fat deposition thereby affecting future milk yield potential. Discrepancies exist whether overfed or overweight heifers at puberty can influence the mammary development and future milk yield potential and performance. The data on post-pubertal nutritional management suggested that body weight at calving and post-pubertal growth rate is important in first lactation milk yield. There is a continuous research need for strategic feeding that accelerates growth of dairy heifers without reduction in subsequent production. Nutritional management from birth, across puberty and during pregnancy is critical for mammary growth and for producing a successful cow. This review will mostly highlight studies carried out on dairy breeds and possible available opportunities to manipulate nutritional status from birth until age at first calving.

    Background The authors examined factors associated with nutritional resilience/vulnerability among preschoolers in the Gaza Strip in 2007, where political violence and deprivation are widespread. Methods This cross-sectional study was carried out in 2007 using random sampling of kindergartens in order to select 350 preschoolers. Binary logistic regression was used to compare resilient (adequate nutrition) and vulnerable (stunted) groups with those with moderate nutrition. Results Approximately 37% of the subjects demonstrated nutritional resilience and 15% were vulnerable. Factors associated with nutritional resilience were child younger age, normal birth weight, actively hand- or spoon-feeding when the child was below two years, and residential stability in the past two years. The only factor associated with nutritional vulnerability was lower total score on the mother's General Health Questionnaire, which we interpret as a marker of maternal mental health. Conclusions Children with low-birth weight and older children had worse nutritional resiliency outcomes. Further, poorer outcomes for children were associated with lower maternal mental health status, as well as increased family residential instability. Our results add to the large literature on the pervasive effects of violence and instability on children and underscore the need for resources for early intervention and for the urgent resolution of the Palestinian and other armed conflicts.

    Exercise and a healthy diet are beneficial after cancer, but are not uniformly adopted by cancer survivors. This study reports on the feasibility, acceptability, and effectiveness of a self-management-based nutrition and exercise intervention for Australian cancer survivors. Adult survivors (n  =  25) during curative chemotherapy (stratum 1[S1]; n  =  11) or post-treatment (stratum 2 [S2]; n  =  14) were recruited prospectively from a single center. The Flinders Living Well Self-Management Program™ (FLW Program) was utilized to establish patient-led nutrition and exercise goals and develop a tailored 12-wk intervention plan. Fortnightly reviews occurred with assessments at baseline, 6 and 12 wk. A recruitment and retention rate of 38% and 84% were observed. Both strata maintained total skeletal muscle mass. Small reductions in body mass index, hip circumference, and percentage body fat, and small increases in hand grip strength and exercise capacity among subjects in both strata were observed. No significant differences were observed between strata; however, significant increases in exercise capacity and global health status for S2 were observed from baseline to 12 wk. FLW Program is a feasible mode of delivering nutrition and exercise intervention to cancer survivors and it appears that there are no barriers to implementing this program early during chemotherapy. Hence, the additive effect of gains achieved over a longer duration is promising and this should be explored in randomized controlled trials adequately powered to observe clinically and statistically significant improvements in relevant outcomes.

    The purpose of this study was to provide preliminary Canadian research assessing nutrition students' cultural competence and to identify areas for future education initiatives in dietetic education that could ultimately improve dietitians' cultural competence. A mixed-methods study was conducted using a 24-item questionnaire that was administered to students enrolled in third- and fourth-year undergraduate nutrition classes (n = 133). In total, 115 questionnaires were analyzed for quantitative data, and 109 were analyzed for qualitative data. The students scored an overall medium-high level of cultural competence. Out of the 5 areas examined (skills, attitudes, awareness, desires, knowledge), students' multicultural knowledge scores were the lowest. It was found that a lower number of barriers to learning about other cultures were significantly associated with a higher overall cultural competence score, and taking a course in cultural foods significantly increased the students' knowledge and overall cultural competence (P ≤ 0.05). The qualitative data found that students felt the cultural competence curriculum had gaps and identified several ideas for improvement. In conclusion, this research data provides novel insights into the cultural competence of Canadian dietetic students and additionally supports future research and curriculum development to enhance cultural competence.

    Personal and organizational performance is determined by commitment and both technical and general competencies, including leadership skills. Academia, however, mainly targets technical aspects in its curricular programs. On the other hand, the inter-disciplinary and multi-sector nature of Nutrition necessitates high levels of collaboration between stakeholders. Leadership development is therefore required in Nutrition. This paper describes the endeavor made in Iran and the Middle-East region, aiming at building leadership capacity among nutrition professionals. The empowered human resource is expected to facilitate nutrition security at the national and regional levels. Since 2007, the development process of the initiative has begun through research, bench marking, and consultation. The “learning organizations,” “leadership from inside-out,” and “transformational leadership” frameworks have been employed as underpinning theories. Main topics have been self-awareness, effective communication, shared visioning, trust building, creativity, and motivating. Outbound team-building activities and coaching have also been included.

    Evidence suggests that maternal and fetal immune dysfunction may impact fetal brain development and could play a role in neurodevelopmental disorders, although the definitive pathophysiological mechanisms are still not completely understood. Stress, malnutrition and physical inactivity are three maternal behavioral lifestyle factors that can influence immune and central nervous system (CNS) functions in both the mother and fetus, and may therefore, increase risk for neurodevelopmental/psychiatric disorders. First, we will briefly review some aspects of maternal-fetal immune system interactions and development of immune tolerance. Second, we will discuss the bidirectional communication between the immune system and CNS and the pathways by which immune dysfunction could contribute to neurodevelopmental disorders. Third, we will discuss the effects of prenatal stress and malnutrition (over and undernutrition) on perinatal programming of the CNS and immune system, and how this might influence neurodevelopment. Finally, we will discuss the beneficial impact of physical fitness during pregnancy on the maternal-fetal unit and infant and how regular physical activity and exercise can be an effective buffer against stress- and inflammatory-related disorders. Although regular physical activity has been shown to promote neuroplasticity and an anti-inflammatory state in the adult, there is a paucity of studies evaluating its impact on CNS and immune function during pregnancy. Implementing stress reduction, proper nutrition and ample physical activity during pregnancy and the childbearing period may be an efficient strategy to counteract the impact of maternal stress and malnutrition/obesity on the developing fetus. Such behavioral interventions could have an impact on early development of the CNS and immune system and contribute to the prevention of neurodevelopmental and psychiatric disorders. Further research is needed to elucidate this relationship and the underlying

    Developmental plasticity in response to environmental cues can take the form of polyphenism, as for the discrete morphs of some insects, or of an apparently continuous spectrum of phenotype, as for most mammalian traits. The metabolic phenotype of adult rats, including the propensity to obesity, hyperinsulinemia, and hyperphagia, shows plasticity in response to prenatal nutrition and to neonatal administration of the adipokine leptin. Here, we report that the effects of neonatal leptin on hepatic gene expression and epigenetic status in adulthood are directionally dependent on the animal's nutritional status in utero. These results demonstrate that, during mammalian development, the direction of the response to one cue can be determined by previous exposure to another, suggesting the potential for a discontinuous distribution of environmentally induced phenotypes, analogous to the phenomenon of polyphenism.

    Zebrafish is one of the most used vertebrate model organisms in molecular and developmental biology, recently gaining popularity also in medical research. However, very little work has been done to assess zebrafish as a model species in nutritional studies in aquaculture in order to utilize the methodological toolbox that this species represents. As a starting point to acquire some baseline data for further nutritional studies, growth of a population of zebrafish was followed for 15 weeks. Furthermore, whole body proteome was screened during development by means of bi-dimensional gel electrophoresis and mass spectrometry. Fish were reared under best practice laboratory conditions from hatching until 103 days post-fertilization (dpf) and regularly fed ad libitum with Artemia nauplii from 12 dpf. A growth burst occurred within 9-51 dpf, reaching a plateau after 65 dpf. Fork length and body weight were significantly lower in males than in females from 58 dpf onwards. Proteomics analysis showed 28 spot proteins differently expressed through development and according to sex. Of these proteins, 20 were successfully identified revealing proteins involved in energy production, muscle development, eye lens differentiation, and sexual maturation. In summary, zebrafish exhibited a rapid growth until approximately 50 dpf, when most individuals started to allocate part of the dietary energy intake for sexual maturation. However, proteomic analysis revealed that some individuals reached sexual maturity earlier and already from 30 dpf onwards. Thus, in order to design nutritional studies with zebrafish fed Artemia nauplii, it is recommended to select a period between 20 and 40 dpf, when fish allocate most of the ingested energy for non-reproductive growth purposes.

    Reliable information about the nutritional status is essential to identify potential critical nutrients and the population groups at risk of deficiency, as well as to develop effective public health policies to counteract unfavorable nutrition patterns that contribute to morbidity and mortality. In this review, the important role of biomarkers in the assessment of nutritional status is outlined, major strengths and limitations of established and new biomarkers are described, and important criteria for biomarker selection and development are discussed. Indeed, biomarkers offer a more objective assessment tool than pure dietary approaches that suffer from inadequate data reporting in particular, although biomarkers are often only measured in subsamples because of the higher costs and proband burden they entail. However, biomarkers are subject to individual variability and influences from other factors besides the nutrient of interest. Rapid turnover or tight control of nutrient concentrations in blood (homeostasis) limits their sensitivity as biomarkers, as in the case of many trace elements. The existence of different forms of a micronutrient in the body adds additional complexity. Functional biomarkers, such as enzyme activities, mirror long-term status better but are subject to confounding factors, and some are influenced by several micronutrients, not specific for only 1, so using a combination of biomarkers is advisable. Additionally, the applicability of a biomarker also depends on the existence of adequate reference values and cutoff points for the target population. Therefore, a careful selection is warranted, especially when biomarkers are to be used in larger samples. PMID:25469404

    A growing body of evidence supports the notion that integrated programs addressing nutrition and stimulation provide stronger impacts on nutritional and developmental outcomes than either intervention alone. When translating evidence into practice, several advantages and challenges for integration can be noted. Combined interventions may be more efficient than separate interventions, because they are intended for the same population and make use of the same facilities, transportation, and client contacts. In addition, for families, particularly for those most at risk, combined interventions can also lead to increased access to services. However, in order for integrated nutrition and early childhood development interventions to be successful, a variety of challenges must be addressed. These include workload of staff and supervisors, communication and coordination among different ministries and among staff in different sectors, and common language and measurement. It must be acknowledged at both the national and community levels that comprehensive, integrated care addressing both the physical and developmental needs of the child is key to promoting optimal health, growth, and development for children.

    We examined the effect of larval and adult nutrition on worker honey bee (Apis mellifera L.) ovary development. Workers were fed high or low-pollen diets as larvae, and high or low-protein diets as adults. Workers fed low-protein diets at both life stages had the lowest levels of ovary development, followed by those fed high-protein diets as larvae and low- quality diets as adults, and then those fed diets poor in protein as larvae but high as adults. Workers fed high-protein diets at both life stages had the highest levels of ovary development. The increases in ovary development due to improved dietary protein in the larval and adult life stages were additive. Adult diet also had an effect on body mass. The results demonstrate that both carry-over of larval reserves and nutrients acquired in the adult life stage are important to ovary development in worker honey bees. Carry-over from larval development, however, appears to be less important to adult fecundity than is adult nutrition. Seasonal trends in worker ovary development and mass were examined throughout the brood rearing season. Worker ovary development was lowest in spring, highest in mid-summer, and intermediate in fall.

    The effects of maternal nutrition on offspring wool production (quality and quantity) were evaluated. Primiparous Rambouillet ewes (n = 84) were randomly allocated to 1 of 6 treatments in a 2 × 3 factorial design. Selenium treatment [adequate Se (ASe, 9.5 μg/kg of BW) vs. high Se (HSe, 81.8 μg/kg of BW)] was initiated at breeding, and maternal nutritional intake [control (CON, 100% of requirements) vs. restricted (60% of CON) vs. overfed (140% of CON)] was initiated at d 50 of gestation. Lamb birth weight was recorded at delivery, and all lambs were placed on the same diet immediately after birth to determine the effects of prenatal nutrition on postnatal wool production and follicle development. At 180 ± 2.2 d of age, lambs were necropsied and pelt weights were recorded. Wool samples were collected from the side and britch areas, whereas skin samples were collected from the side of each lamb only. Although Se status did not influence side staple length in males, female lambs born from ewes on the ASe treatment had a shorter staple length (P < 0.05) when compared with females from ewes on the HSe treatment. Maternal nutritional intake and Se status did not influence (P ≥ 0.23) wool characteristics on the britch. However, at the britch, wool from female lambs had a reduced comfort factor (P = 0.01) and a greater (P = 0.02) fiber diameter compared with wool from male lambs. Maternal Se supplementation, maternal nutritional plane, sex of the offspring, or their interactions had no effect (P > 0.13) on primary (29.10 ± 1.40/100 µm(2)) and secondary (529.84 ± 21.57/100 µm(2)) wool follicle numbers. Lambs from ASe ewes had a greater (P = 0.03) secondary:primary wool follicle ratio compared with lambs from HSe ewes (20.93 vs. 18.01 ± 1.00). Despite similar postnatal diets, wool quality was affected by maternal Se status and the maternal nutritional plane.

    This review highlights the fundamental role of nutrition in the maintenance of health, the immune response, and disease prevention. Emerging global mechanistic insights in the field of nutritional immunology cannot be gained through reductionist methods alone or by analyzing a single nutrient at a time. We propose to investigate nutritional immunology as a massively interacting system of interconnected multistage and multiscale networks that encompass hidden mechanisms by which nutrition, microbiome, metabolism, genetic predisposition, and the immune system interact to delineate health and disease. The review sets an unconventional path to apply complex science methodologies to nutritional immunology research, discovery, and development through “use cases” centered around the impact of nutrition on the gut microbiome and immune responses. Our systems nutritional immunology analyses, which include modeling and informatics methodologies in combination with pre-clinical and clinical studies, have the potential to discover emerging systems-wide properties at the interface of the immune system, nutrition, microbiome, and metabolism.

    Background The Australian Guide to Healthy Eating (AGHE) for pregnancy provides a number of food- and nutrition-related recommendations to assist pregnant women in optimizing their dietary behavior. However, there are limited data demonstrating pregnant women’s knowledge of the AGHE recommendations. This study investigated Australian pregnant women’s knowledge of the AGHE and related dietary recommendations for maintaining a healthy pregnancy. The variations in nutrition knowledge were compared with demographic characteristics. Methods A cross-sectional study assessed eight different nutrition knowledge domains and the demographic characteristics of pregnant women. Four hundred women across Australia completed a multidimensional online survey based on validated and existing measures. Results More than half of the pregnant women surveyed (65%) were not familiar with the AGHE recommendations. The basic recommendations to eat more fruit, vegetables, bread, and cereals but less meat were poorly understood. An in-depth investigation of knowledge of nutrition information revealed misconceptions in a range of areas, including standard serving size, nutrients content of certain foods, energy density of fat, and the importance of key nutrients in pregnancy. Univariate analysis revealed significant demographic variation in nutrition knowledge scores. Multiple regression analysis confirmed the significant independent effects on respondents’ nutrition knowledge score (P<0.000) of the education level, income, age, stage of pregnancy, language, and having a health/nutrition qualification. The model indicated that independent variables explained 33% (adjusted R2) of the variance found between respondents’ knowledge scores. Conclusion Australian pregnant women’s knowledge regarding AGHE for pregnancy and other key dietary recommendations is poor and varies significantly with their demographic profile. The setting of dietary guidelines is not sufficient to ensure

    A growing body of scientific and epidemiological evidence indicates that diet and health are related: diet may be a risk factor or have potential protective effects. As a consequence, the focus of nutrition research has experienced a shift towards qualitative aspects of diet which could influence chronic disease, longevity, quality of life and physical and cognitive performance, leading to the development of Community Nutrition. The main undertakings in a Community Nutrition Unit are related to the identification, assessment and monitoring of nutrition problems at the community level and to planning, design, implementation and evaluation of nutrition intervention programs. Such programs combine a number of suitable strategies in a whole population approach, a high risk approach or an approach targeted at specific population groups, and are implemented in different settings, such as the work place, schools or community organizations. Community nutrition interventions aim to gradually achieve change in eating patterns towards a healthier profile. Community Nutrition programs require the use of a combination of strategies and a working group of people from different backgrounds. Many factors influence the nutritional status of an individual or a population. In order to gain effective work output, sound understanding of these patterns and a practical surveillance system are required. PMID:17424768

    2014-12-01

    The human brain confronts two major challenges during its development: (i) meeting a very high energy requirement, and (ii) reliably accessing an adequate dietary source of specific brain selective nutrients needed for its structure and function. Implicitly, these energetic and nutritional constraints to normal brain development today would also have been constraints on human brain evolution. The energetic constraint was solved in large measure by the evolution in hominins of a unique and significant layer of body fat on the fetus starting during the third trimester of gestation. By providing fatty acids for ketone production that are needed as brain fuel, this fat layer supports the brain's high energy needs well into childhood. This fat layer also contains an important reserve of the brain selective omega-3 fatty acid, docosahexaenoic acid (DHA), not available in other primates. Foremost amongst the brain selective minerals are iodine and iron, with zinc, copper and selenium also being important. A shore-based diet, i.e., fish, molluscs, crustaceans, frogs, bird's eggs and aquatic plants, provides the richest known dietary sources of brain selective nutrients. Regular access to these foods by the early hominin lineage that evolved into humans would therefore have helped free the nutritional constraint on primate brain development and function. Inadequate dietary supply of brain selective nutrients still has a deleterious impact on human brain development on a global scale today, demonstrating the brain's ongoing vulnerability. The core of the shore-based paradigm of human brain evolution proposes that sustained access by certain groups of early Homo to freshwater and marine food resources would have helped surmount both the nutritional as well as the energetic constraints on mammalian brain development.

    Adolescence is a critical period, because major physical and psychologic changes occur during a very short period of time. Changes in dietary habits may induce different types of nutritional disorders and are likely to track into adulthood. The aim of this review is to describe the key findings related to nutritional status in European adolescents participating in the HELENA (Healthy Lifestyle in Europe by Nutrition in Adolescence) study. We performed a cross-sectional study in 3528 (1845 females) adolescents aged 12.5–17.5 y. Birth weight was negatively associated with abdominal fat mass in adolescents and serum leptin concentrations (in female adolescents), providing additional evidence for a programming effect of birth weight on energy homeostasis control. Breakfast consumption was associated with lower body fat content and healthier cardiovascular profile. Adolescents eat half of the recommended amount of fruit and vegetables and less than two-thirds of the recommended amount of milk and milk products but consume more meat and meat products, fats, and sweets than recommended. For beverage consumption, sugar-sweetened beverages, sweetened milk, low-fat milk, and fruit juice provided the highest amount of energy. Although the intakes of saturated fatty acids (FAs) and salt were high, the intake of polyunsaturated FAs was low. Adolescents spent, on average, 9 h/d of their waking time (66–71% and 70–73% of the registered time in boys and girls, respectively) in sedentary activities. Factors associated with adolescents’ sedentary behavior included the following: 1) age; 2) media availability in the bedroom; 3) sleeping time; 4) breakfast consumption; and 5) season.

    Ninety-five percent of persons over the age of 65 years live in the community and benefit from community-based health and nutrition services. The purpose of this project was to evaluate diet, function, and mental health in 40 men and women aged 65 years and older who were residing in a large metropolitan community. Nutritional status was assessed using two 24-hour recalls, 5 days of food records, a food frequency, and anthropometric measurements. Participants responded to standardized activities of daily living and instrumental activities of daily living instruments and an investigator-developed, performance-based appraisal of food preparation and management. Cognition and mood were assessed using the Folstein Mini-Mental Examination and the Yesavage Depression Scale. The nutrient intakes for individuals were compared with the Recommended Dietary Allowances (RDAs) and the Food Guide Pyramid. Mean energy intake was 1,625 kcal (range = 787 to 2,910 kcal); 7 persons consumed more than 2,000 kcal. The mean vitamin and mineral intake for participants met the RDAs except for calcium, vitamin D, zinc, and magnesium intakes. The average percentages of carbohydrate, protein, and fat were 53%, 16%, and 30%, respectively. Nutritional assessments of subjects with and without congregate meals were contrasted. Six of the 13 congregate-meal participants were at nutritional risk, compared with 6 of 27 not receiving congregate meals. The interrelationships of diet, functional status, and mental health factors were examined along with recommendations for future data collection in similar studies. PMID:9597028

We performed a narrative review of the publications of the NHS and NHS II between 1976 and 2016. Results. Through periodic assessment of diet by validated dietary questionnaires over 40 years, the NHSs have identified dietary determinants of diseases such as breast and other cancers; obesity; type 2 diabetes; cardiovascular, respiratory, and eye diseases; and neurodegenerative and mental health disorders. Nutritional biomarkers were assessed using blood, urine, and toenail samples. Robust findings, from the NHSs, together with evidence from other large cohorts and randomized dietary intervention trials, have contributed to the evidence base for developing dietary guidelines and nutritional policies to reduce intakes of trans fat, saturated fat, sugar-sweetened beverages, red and processed meats, and refined carbohydrates while promoting higher intake of healthy fats and carbohydrates and overall healthful dietary patterns. Conclusions. The long-term, periodically collected dietary data in the NHSs, with documented reliability and validity, have contributed extensively to our understanding of the dietary determinants of various diseases, informing dietary guidelines and shaping nutritional policy.

    Background: Knowledge about how to support nutritional self-care in the vulnerable elderly living in their own homes is an important area for health care professionals. The aim of this case study was to evaluate the effects of nutritional intervention by comparing perceived health, sense of coherence, self-care ability, and nutritional risk in two older home-dwelling individuals before, during, and after intervention and to describe their experiences of nutritional self-care before and after intervention. Methods: A study circle was established to support nutritional self-care in two older home-dwelling individuals (≥65 years of age), who participated in three meetings arranged by health professionals over a period of six months. The effects of this study circle were evaluated using the Nutritional Form For the Elderly, the Self-care Ability Scale for the Elderly (SASE), the Appraisal of Self-care Agency scale, the Sense of Coherence (SOC) scale, and responses to a number of health-related questions. Qualitative interviews were performed before and after intervention to interpret the changes that occurred during intervention. Results: A reduced risk of undernutrition was found for both participants. A higher total score on the SASE was obtained for one participant, along with a slightly stronger preference for self-care to maintain sufficient food intake, was evident. For the other participant, total score on the SASE decreased, but the SOC score improved after intervention. Decreased mobility was reported, but this did not influence his food intake. The study circle was an opportunity to express personal views and opinions about food intake and meals. Conclusion: An organized meeting place for dialogue between older home-dwelling individuals and health care professionals can stimulate the older person’s engagement, consciousness, and learning about nutritional self-care, and thereby be of importance in reducing the risk of undernutrition.

    Within the longitudinal study on nutrition and health status in an aging population of Giessen, Germany, baseline measurements with regard to antioxidant status were obtained in 85 free living elderly persons. The subjects were at least 60 years old, non-smoking, feeding themselves, and not supplementing any vitamins or minerals. Dietary intake of nutrients was assessed by means of a 3-day estimated food record, which was especially developed and validated for this study. Antioxidant status was evaluated by fasting plasma concentrations of vitamin C, E, beta-carotene, and selenium. The results show that in this study group self-determined nutrition provides enough nutrients to yield a good antioxidant status in the advanced age. Although no differences could be detected in dietary intake of vitamin C, E, and beta-carotene between males and females, significantly higher plasma concentrations of all substances investigated were found in females when compared to males.

    Nutritional metabolomics is rapidly maturing to use small molecule chemical profiling to support integration of diet and nutrition in complex biosystems research. These developments are critical to facilitate transition of nutritional sciences from population-based to individual-based criteria for nutritional research, assessment and management. This review addresses progress in making these approaches manageable for nutrition research. Important concept developments concerning the exposome, predictive health and complex pathobiology, serve to emphasize the central role of diet and nutrition in integrated biosystems models of health and disease. Improved analytic tools and databases for targeted and non-targeted metabolic profiling, along with bioinformatics, pathway mapping and computational modeling, are now used for nutrition research on diet, metabolism, microbiome and health associations. These new developments enable metabolome-wide association studies (MWAS) and provide a foundation for nutritional metabolomics, along with genomics, epigenomics and health phenotyping, to support integrated models required for personalized diet and nutrition forecasting.

    It would be of enormous public health importance if diet and physical activity—both modifiable behavioral factors--were causally related to cancer. Nevertheless, the nutritional epidemiology of cancer remains problematic, in part because of persistent concerns that standard questionnaires measure diet and physical activity with too much error. We present a new strategy for addressing this measurement error problem. First, as background, we note that food frequency and physical activity questionnaires require respondents to report ‘typical’ diet or activity over the previous year or longer. Multiple 24-hour recalls (24HR), based on reporting only the previous day’s behavior, offer potential cognitive advantages over the questionnaires, and biomarker evidence suggests the 24HR is more accurate than the food frequency questionnaire. The expense involved in administering multiple 24HRs in large epidemiologic studies, however, has up to now been prohibitive. In that context, we suggest that internet-based 24HRs, for both diet and physical activity, represent a practical and cost-effective approach for incorporating multiple recalls in large epidemiologic studies. We discuss 1) recent efforts to develop such internet-based instruments and their accompanying software support systems; 2) ongoing studies to evaluate the feasibility of using these new instruments in cohort studies; 3) additional investigations to gauge the accuracy of the internet-based recalls vis-à-vis standard instruments and biomarkers; and 4) new statistical approaches for combining the new instruments with standard assessment tools and biomarkers The incorporation of internet-based 24HRs into large epidemiologic studies may help advance our understanding of the nutritional determinants of cancer.

    Background Undernutrition continues to pose challenges to Uganda's children, but there is limited knowledge on its association with physical and intellectual development. Objective In this cross-sectional study, we assessed the nutritional status and milestone development of 6- to 8-month-old children and associated factors in two districts of southwestern Uganda. Design Five hundred and twelve households with mother–infant (6–8 months) pairs were randomly sampled. Data about background variables (e.g. household characteristics, poverty likelihood, and child dietary diversity scores (CDDS)) were collected using questionnaires. Bayley Scales of Infant and Toddler Development (BSID III) and Ages and Stages questionnaires (ASQ) were used to collect data on child development. Anthropometric measures were used to determine z-scores for weight-for-age (WAZ), length-for-age (LAZ), weight-for-length (WLZ), head circumference (HCZ), and mid-upper arm circumference. Chi-square tests, correlation coefficients, and linear regression analyses were used to relate background variables, nutritional status indicators, and infant development. Results The prevalence of underweight, stunting, and wasting was 12.1, 24.6, and 4.7%, respectively. Household head education, gender, sanitation, household size, maternal age and education, birth order, poverty likelihood, and CDDS were associated (p<0.05) with WAZ, LAZ, and WLZ. Regression analysis showed that gender, sanitation, CDDS, and likelihood to be below the poverty line were predictors (p<0.05) of undernutrition. BSID III indicated development delay of 1.3% in cognitive and language, and 1.6% in motor development. The ASQ indicated delayed development of 24, 9.1, 25.2, 12.2, and 15.1% in communication, fine motor, gross motor, problem solving, and personal social ability, respectively. All nutritional status indicators except HCZ were positively and significantly associated with development domains. WAZ was the main predictor for

    Background: Improved glycated hemoglobin (Hb A1c) delays the progression of microvascular and macrovascular complications in individuals with type 1 diabetes (T1D). We previously showed that higher baseline intakes of n–3 (ω-3) fatty acids and leucine are associated with preserved β cell function 2 y later in youth with T1D. Objective: In the current study, we extend this work to explore the longitudinal associations of nutritional factors with Hb A1c in youth with T1D. Design: We included 908 T1D youth with baseline and follow-up Hb A1c measurements. Nutritional factors assessed at baseline were as follows: breastfeeding status and timing of complimentary food introduction; intakes of leucine, carbohydrates, protein, fat, and fiber estimated from a food-frequency questionnaire (FFQ); and plasma biomarkers for vitamins D and E, eicosapentaenoic acid (EPA), and docosahexaenoic acid. We fit linear regression models adjusted for baseline Hb A1c, sociodemographic variables, diabetes-related variables, time between baseline and follow-up visits, saturated fat, physical activity, and for FFQ-derived nutrients, total calories. The vitamin D model was further adjusted for season and body mass index z score. Results: The mean ± SD age and diabetes duration at baseline was 10.8 ± 3.9 y and 10.1 ± 5.8 mo, respectively. A total of 9.3% of participants had poor Hb A1c (value ≥9.5%) at baseline, which increased to 18.3% during follow-up (P < 0.0001). Intakes of EPA (β = −0.045, P = 0.046), leucine (β = −0.031, P = 0.0004), and protein (β = −0.003, P = 0.0002) were significantly negatively associated with follow-up Hb A1c after adjustment for confounders. Intake of carbohydrates was significantly positively (β = 0.001, P = 0.003) associated with follow-up Hb A1c after adjustment for confounders. Conclusions: Several nutritional factors may be associated with Hb A1c during early stages of disease progression in youth recently diagnosed with T1D. In addition to

    Malnutrition is a relatively common problem in patients on hemodialysis (HD) and is associated with increased morbidity and mortality in affected patients. With the aid of subjective global assessment (SGA), a semi-quantitative scale for estimating nutritional status, the malnutrition score (MS), has been developed. The MS incorporates advantages of the SGA while extending the reliability and precision. This study was performed to assess the nutritional status in patients on HD at the Mostafa Khomeini Hospital, Tehran, Iran. Based on the MS, which consists of seven components--weight change, dietary intake, gastrointestinal (GI) symptoms, functional capacity, comorbidity, subcutaneous fat, and muscle wasting--we conducted a cross-sectional descriptive-analytic study on 54 HD patients (35 males, 19 females) with age range of 18 to 82 years (mean 44.2 +/- 19.8 years). Each component of the MS has a score from one (normal) to five (very severe). Anthropometric measurements including triceps skin-fold thickness (TSF), mid-arm circumference (MAC) and mid-arm muscle circumference (MAMC) were taken on all patients. Also, the body mass index and TSF/MAC ratio were calculated. Relevant laboratory parameters were checked. The duration of HD of the study patients ranged between 5 and 36 months (mean 19.5 +/- 1.5 months). Data analysis was carried out using the SPSS, Pearson correlation, 't' test and regression. Based on the MS, 40.7% of patients had malnutrition (mean score 13.8 +/- 2.8). There were statistically significant correlations between TSF (p < 0.01), MAC (p = 0.02), MAMC (p = 0.01), TSF/MAC ratio (p < 0.001), BMI (p = 0.028), serum albumin concentration (p = 0.021) and MS. No statistically significant correlation was found between the MS and urea reduction ratio, protein catabolic rate, age, gender, or duration of dialysis. After 1 year, 20.4% of patients died because of dialysis-related complications. The mortality rate did not show significant correlation with

    Children with autism spectrum disorder (ASD) have problems of food selectivity, implying risks of nutritional deficiencies. The aim was to compare intakes of macro and micronutrients and body mass index in ASD and typically developing (TD) children. In a case-control study, 3-day food diaries and anthropometric measurements were completed for ASD (n = 40) and TD (n = 113) children (aged 6-10 years) living in the same area. Body mass indices were below the 5th percentile in 20 % of ASD versus 8.85% of TD children. We found intakes were lower for fluoride (p = 0.017) and higher for vitamin E (p = 0.001). There was limited food variety and inadequacy of some intakes suggests that routine monitoring of ASD children should include assessment of their dietary habits, as well as anthropometric measurements.

    Background Food insecurity and poor nutrition are key barriers to anti-retroviral therapy (ART) adherence. Culturally-appropriate and sustainable interventions that provide nutrition counseling for people on ART and of diverse nutritional statuses are needed, particularly given rising rates of overweight and obesity among people living with HIV (PLHIV). Methods As part of scale-up of a nutritional counseling intervention, we recruited and trained 17 peer counselors from 14 government-run HIV clinics in Honduras to deliver nutritional counseling to ART patients using a highly interactive curriculum that was developed after extensive formative research on locally available foods and dietary patterns among PLHIV. All participants received the intervention; at baseline and 2 month follow-up, assessments included: 1) interviewer-administered, in-person surveys to collect data on household food insecurity (15-item scale), nutritional knowledge (13-item scale), dietary intake and diversity (number of meals and type and number of food groups consumed in past 24 hours); and 2) anthropometric measures (body mass index or BMI, mid-upper arm and waist circumferences). We used multivariable linear regression analysis to examine changes pre-post in food insecurity and the various nutritional outcomes while controlling for baseline characteristics and clinic-level clustering. Results Of 482 participants at baseline, we had complete follow-up data on 356 (74%), of which 62% were women, median age was 39, 34% reported having paid work, 52% had completed primary school, and 34% were overweight or obese. In multivariate analyses adjusting for gender, age, household size, work status, and education, we found that between baseline and follow-up, household food insecurity decreased significantly among all participants (β=−0.47, p<.05) and among those with children under 18 (β=−1.16, p<.01), while nutritional knowledge and dietary intake and diversity also significantly improved

    The pre-school years (i.e., 1–5 years of age) is a time of rapid and dramatic postnatal brain development, i.e., neural plasticity, and of fundamental acquisition of cognitive development i.e., working memory, attention and inhibitory control. Also, it is a time of transition from a direct maternal mediation/selection of diet-based nutrition to food selection that is more based on self-selection and self-gratification. However, there have been fewer published studies in pre-school children than in infants or school-aged children that examined the role of nutrition in brain/mental development (i.e., 125 studies vs. 232 and 303 studies, respectively during the last 28 years, Figure 1). This may arise because of age-related variability, in terms of individual differences in temperament, linguistic ability, and patterns of neural activity that may affect assessment of neural and cognitive development in pre-school children. In this review, we suggest several approaches for assessing brain function in children that can be refined. It would be desirable if the discipline developed some common elements to be included in future studies of diet and brain function, with the idea that they would complement more targeted measures based on time of exposure and understanding of data from animal models. Underlining this approach is the concepts of “window of sensitivity” during which nutrients may affect postnatal neural development: investigators and expert panels need to specifically look for region-specific changes and do so with understanding of the likely time window during which the nutrient was, or was not available.

    It is increasingly recognized that developing countries are undergoing an epidemiologic transition similar to that which occurred in industrialized countries in previous centuries. While infectious diseases are still the main cause of morbidity and mortality, there is a marked increase in chronic non-communicable diseases, particularly in the most advanced developing countries, and these diseases are expected to take the lead in a decade or two. Most of these diseases, above all coronary heart diseases, stroke and diabetes, are related to diet and lifestyles, for example tobacco and alcohol consumption. As a matter of fact, these societies are also facing a growing epidemic of overweight and obesity, due to the frequent energetic imbalance between energy-dense food consumption and reduced daily physical expenditure. This health transition, favoured by demographic changes towards aging populations, is occurring at an increased pace in urban societies widely exposed to the modernization of lifestyle, sedentary occupation, and to lipid- and sugar-rich food, often poor in fibre and micronutrients. Increased world access to cheaper vegetable oil is thought to have triggered off this accelerated and generalized trend, though animal food, rich in saturated fat, and imported or locally-made industrialized food also play a role. While increased national and household incomes facilitate the initial change, as the transition advances poor people progressively become the main victims, as has been observed in the more advanced developing countries. Metabolic imprinting due to intra-uterine and infant malnutrition, which are still common in these societies, is also thought to play a significant role in the increase in the expression of insulin resistance, obesity and chronic diseases when these children are exposed to abundant food and modern lifestyle, later in life.

    Over recent years, modelling approaches from nutritional ecology (known as Nutritional Geometry) have been increasingly used to describe how animals and some other organisms select foods and eat them in appropriate amounts in order to maintain a balanced nutritional state maximising fitness. These nutritional strategies profoundly affect the physiology, behaviour and performance of individuals, which in turn impact their social interactions within groups and societies. Here, we present a conceptual framework to study the role of nutrition as a major ecological factor influencing the development and maintenance of social life. We first illustrate some of the mechanisms by which nutritional differences among individuals mediate social interactions in a broad range of species and ecological contexts. We then explain how studying individual- and collective-level nutrition in a common conceptual framework derived from Nutritional Geometry can bring new fundamental insights into the mechanisms and evolution of social interactions, using a combination of simulation models and manipulative experiments.

Food and nutrition are themselves broad topics, and each is influenced by a myriad of local and international forces, making them both interesting and important, but also challenging in their complexity. It is especially difficult to deal with such a vast and complicated terrain in such a short paper, and one must inevitably deal only superficially with a number of complex areas. This paper will review a number of key forces for change in the global system, with a focus on the implications of each for food and nutrition. Each area is central to the experience of economic, social and political development, particularly in the period since 1945, and each is tied in various ways with that complex and interrelated set of changes that we call globalisation. Seven key factors will be explored: global population growth, leading to strong pressures on world availability of arable land and food; increasing integration in the global economy, as measured through such things as trade, financial flows and information exchanges, and with specific implications for the food industry and for trade in food products; growing gaps between rich and poor countries; similar increases in disparities between rich and poor segments within individual countries; the rapid growth of cities in the developing world, resulting in massive challenges for the food supply systems of many nations; the growth within some countries, for example in a number of Asian countries, of a "new middle class" with distinctive patterns of consumption; and, high levels of population movements between countries resulting in the creation of significant communities of immigrants in a number of nations. Examples will be drawn from the two regions familiar to the author, Asia and Sub-Saharan Africa, but with a particular emphasis on East Asia. PMID:15228985

    Milk has been well established as the optimal nutrition source for infants, yet there is still much to be understood about its molecular composition. Therefore, our objective was to develop and compare comprehensive milk proteomes for human and rhesus macaques to highlight differences in neonatal nutrition. We developed a milk proteomics technique that overcomes previous technical barriers including pervasive post-translational modifications and limited sample volume. We identified 1606 and 518 proteins in human and macaque milk, respectively. During analysis of detected protein orthologs, we identified 88 differentially abundant proteins. Of these, 93% exhibited increased abundance in human milk relative to macaque and include lactoferrin, polymeric immunoglobulin receptor, alpha-1 antichymotrypsin, vitamin D-binding protein, and haptocorrin. Furthermore, proteins more abundant in human milk compared with macaque are associated with development of the gastrointestinal tract, the immune system, and the brain. Overall, our novel proteomics method reveals the first comprehensive macaque milk proteome and 524 newly identified human milk proteins. The differentially abundant proteins observed are consistent with the perspective that human infants, compared with nonhuman primates, are born at a slightly earlier stage of somatic development and require additional support through higher quantities of specific proteins to nurture human infant maturation.

    Benefits and risks of nutrition support were evaluated in 31 malnourished children with newly diagnosed Wilms' tumor managed according to the third National Wilms' Tumor Study protocol. Patients were classified at diagnosis as being at high nutritional risk (HNR, n = 19) or low nutritional risk (LNR, n = 12). Ten HNR patients were randomized to central parenteral nutrition (CPN) and nine HNR patients were randomized to peripheral parenteral nutrition (PPN) plus enteral nutrition (EN) for 4 weeks of initial intense treatment and EN (nutritional counseling, oral foods and supplements) thereafter. Thirteen HNR patients (seven CPN, six PPN) completed the protocol. Twelve LNR patients received EN; 11 Stage I malnourished patients were randomized to 10 or 26 weeks of chemotherapy. Dietary, anthropometric, and biochemical data were determined for HNR patients at weeks 0-4, 6, 13, 19, and 26 and for LNR patients at weeks 1, 2, 5, and 26. In HNR patients, adequate parenteral nutrition support reversed protein energy malnutrition (PEM), and prevented chemotherapy and radiotherapy delays due to granulocytopenia. CPN was superior to PPN in reversing PEM: energy intake, weight gain, and retinol binding protein were higher (P less than 0.05). LNR patients lost weight and fat reserves in the first 2 weeks of treatment; depletion persisted at week 5, and 25% had chemotherapy delays. Thereafter, EN reversed PEM in patients with both chemotherapy regimens. These data suggest that CPN is preferable during initial intense treatment for HNR patients, and that, although EN is ineffective in preventing depletion and treatment delays in the first 5 weeks of treatment for LNR patients, it is effective thereafter.

  17. Nutritional Assessment.

    Nutritional assessment focuses on evaluation of animal-specific, diet-specific, feeding management, and environmental factors. Assessment includes evaluation of a patient's medical history, comprehensive diet history, and physical examination including body weight, body condition, and muscle condition. Diagnostic testing may identify comorbidities associated with obesity or concurrent health conditions that need to be considered when developing a nutrition plan. When obesity is diagnosed during the nutritional assessment this finding along with health implications must be clearly communicated to the pet owner. Careful consideration of animal-specific, diet-specific, owner-specific, and environmental factors allows the clinician to develop a specific nutrition plan tailored to the needs of pet and owner.

    The salmon fishing industry of the Pacific Coast is dependent on the survival and propagation of 5 species of salmon which spawn in rivers of that portion of the North American continent extending from California to Alaska. The development of these rivers for power, irrigation, flood control and other projects has drastically reduced the natural spawning areas available to salmon. To prevent the extinction of these fish and the concurrent losses to the fishing industry, various State and Federal agencies have initiated a major program of artificial propagation. This area of animal husbandry has received little attention from nutritional workers and there is a paucity of information on the nutritional requirements of salmon. To supply this essential information the U. S. Fish and Wildlife Service established the Salmon Nutrition Laboratory at Cook, Washington in 1952. This report represents the first of a series which will be presented from the laboratory.

    Despite the increased emphasis on chronic non-communicable diseases, there are notable deficits about nutrition education in many medicine training programs particularly gastroenterology fellowship programs. In the present cross-sectional study, we examined the nutritional knowledge related to clinical nutrition among Iranian gastroenterology fellows. Thirty-six gastroenterology fellows currently enrolled in a gastroenterology fellowship program completed a questionnaire, including two sections. The first of which assessed the gastroenterology fellows experience about nutrition training, nutrition management of patients with gastrointestinal (GI) disorders and evaluating perceived nutrition education needs. The second section consisted of multiple choice questions that assessed nutritional knowledge. A total of 32 gastroenterology fellows completed the first section. The majority of gastroenterology fellows failed to partake in any nutrition education during their fellowship training particularly for inpatients despite the availability to participate in the nutrition training especially for the purpose of nutrition support. Mean correct response rates for the second section was 38%. The highest mean score was seen in nutrition assessment (48.1%), followed by scores of 40.5% in nutrition support, 37.0% nutrition in GI disease, and 25.0% in micro and macronutrients. Iranian gastroenterology fellows have serious deficits in their nutrition knowledge. This study paves the way for the development of an education program to improve nutritional knowledge of gastroenterology fellows.

    Replacing cows in the herd is second only to nutrition as the single greatest input cost in cow/calf beef production. The increased availability of cereal grains for feeding livestock has allowed replacement heifers to enter the production system at younger ages. Many heifer development programs feed to ensure heifers reach puberty before the time that they are mated to calve at 2 yr of age. Nutrition level during development has been associated with altered milk production and stayability. We hypothesized that heifers exposed to a lower nutrition level during the peripubertal period would have less methylation of the DNA in the mammary gland and ovarian cortex. We also hypothesized that the ovarian reserve would decrease in heifers fed for rapid growth compared to heifers fed for slow growth during puberty. At 257±1 d of age, heifers in the Stair-Step treatment (n=6) received 157 kcal ME/BW kg0.75 for 84 d and heifers in the Conventional treatment (n=6) were offered 228 kcal ME/BW kg0.75. At d 84, heifers were fed for an additional 83 d. Stair-Step heifers were offered 277 kcal ME/BW kg0.75, and heifers on the Conventional treatment received 228 kcal ME/BW kg0.75. Mammary weights (P=0.43), capillary area density (P=0.74), and capillary surface density (P=0.18) did not differ between treatments and neither did alveolar number (P=0.55) and alveolar density (P=0.49). Reproductive tract weights (P=0.69) and ovarian weight (P=0.68) and ovarian size (P>0.75) did not differ between treatments. In histological sections, Stair-Step heifers had more primordial follicles than Conventional heifers (P=0.02), but primary (P=0.59) and secondary (P=0.15) follicles did not differ. Global methylation of parenchymal tissue (P=0.82), mammary fat pad (P=0.45), and ovarian cortex (P=0.14) did not differ between treatments. Anterior pituitary weight did not differ between treatments (P=0.16). Our hypothesis that modifying peripubertal nutrition modifies global methylation of the

    Over the past 40 years, tourism-based economic development has transformed social and economic conditions in the Yucatan Peninsula, Mexico. We address how these changes have influenced anthropometric indicators of growth and nutritional status in Yalcoba, a Mayan farming community involved in the circular migration of labor in the tourist economy. Data are presented on stature and weight for children measured in 1938 in the Yucatan Peninsula and from 1987 to 1998 in the Mayan community of Yalcoba. In addition, stature, weight and BMI are presented for adults in Yalcoba based on clinic records. Childhood stature varied little between 1938 and 1987. Between 1987 and 1998 average male child statures increased by 2.6cm and female child statures increased by 2.7cm. Yet, 65% of children were short for their ages. Between 1987 and 1998, average child weight increased by 1.8kg. Child BMIs were similar to US reference values and 13% were considered to be above average for weight. Forty percent of adult males and 64% of females were overweight or obese. The anthropometric data from Yalcoba suggest a pattern of stunted children growing into overweight adults. This pattern is found elsewhere in the Yucatan and in much of the developing world where populations have experienced a nutrition transition toward western diets and reduced physical activity levels.

    The modernization during the last century resulted in urbanization coupled with modifications in lifestyles and dietary habits. In the same era, industrial developments made it easier to meet the requirements for processed foods. However, consumers are now interested in minimally processed foods owing to increase in their awareness to have fruits and vegetables with superior quality, and natural integrity with fewer additives. The food products deteriorate as a consequence of physiological aging, biochemical changes, high respiration rat,e and high ethylene production. These factors contribute substantially to discoloration, loss of firmness, development of off-flavors, acidification, and microbial spoilage. Simultaneously, food processors are using emerging approaches to process perishable commodities, along with enhanced nutritional and sensorial quality. The present review article is an effort to utilize the modern approaches to minimize the processing and deterioration. The techniques discussed in this paper include chlorination, ozonation, irradiation, photosensitization, edible coating, natural preservative use, high-pressure processing, microwave heating, ohmic heating, and hurdle technology. The consequences of these techniques on shelf-life stability, microbial safety, preservation of organoleptic and nutritional quality, and residue avoidance are the limelight of the paper. Moreover, the discussion has been made on the feasibility and operability of these techniques in modern-day processing.

  7. The FRD3 citrate effluxer promotes iron nutrition between symplastically disconnected tissues throughout Arabidopsis development.

    We present data supporting a general role for FERRIC REDICTASE DEFECTIVE3 (FRD3), an efflux transporter of the efficient iron chelator citrate, in maintaining iron homeostasis throughout plant development. In addition to its well-known expression in root, we show that FRD3 is strongly expressed in Arabidopsis thaliana seed and flower. Consistently, frd3 loss-of-function mutants are defective in early germination and are almost completely sterile, both defects being rescued by iron and/or citrate supply. The frd3 fertility defect is caused by pollen abortion and is associated with the male gametophytic expression of FRD3. Iron imaging shows the presence of important deposits of iron on the surface of aborted pollen grains. This points to a role for FRD3 and citrate in proper iron nutrition of embryo and pollen. Based on the findings that iron acquisition in embryo, leaf, and pollen depends on FRD3, we propose that FRD3 mediated-citrate release in the apoplastic space represents an important process by which efficient iron nutrition is achieved between adjacent tissues lacking symplastic connections. These results reveal a physiological role for citrate in the apoplastic transport of iron throughout development, and provide a general model for multicellular organisms in the cell-to-cell transport of iron involving extracellular circulation.

    Background Although widely available, the general public, cancer patients, and cancer survivors have difficulties accessing evidence-based information on nutrition and cancer. It is challenging to distinguish myths from facts, and sometimes conflicting information can be found in different places. The public and patients would benefit from evidence-based, correct, and clear information from an easily recognizable source. Objective The aim of this project is to make scientific information available for the general public, cancer patients, and cancer survivors through a website. The aim of this paper is to describe and evaluate the development of the website as well as related statistics 1st year after its launch. Methods To develop the initial content for the website, the website was filled with answers to frequently asked questions provided by cancer organizations and the Dutch Dietetic Oncology Group, and by responding to various fiction and facts published in the media. The website was organized into 3 parts, namely, nutrition before (prevention), during, and after cancer therapy; an opportunity for visitors to submit specific questions regarding nutrition and cancer was included. The website was pretested by patients, health care professionals, and communication experts. After launching the website, visitors’ questions were answered by nutritional scientists and dieticians with evidence- or eminence-based information on nutrition and cancer. Once the website was live, question categories and website statistics were recorded. Results Before launch, the key areas for improvement, such as navigation, categorization, and missing information, were identified and adjusted. In the 1st year after the launch, 90,111 individuals visited the website, and 404 questions were submitted on nutrition and cancer. Most of the questions were on cancer prevention and nutrition during the treatment of cancer. Conclusions The website provides access to evidence- and eminence

    Peak bone mass (PBM) is defined as the highest bone mineral content (BMC) reached in any period of a person's life. The bone mass once gained at the peak begins to decline and continues to do so until the end of life. The aim of this study was to evaluate the relationship of nutrition and physical activity on bone mineralization during the adolescent period. The study took place at Hacettepe University Ihsan Doğramaci Children's Hospital Adolescent Unit. One hundred fourteen healthy male adolescents applying for different reasons, with ages ranging between 11.1 and 16.5 years, participated in the study. When all adolescents were evaluated, no statistical relationship between the daily calcium intake, BMC and bone mineral density (BMD) was obtained. However, a positive statistical relationship was found for those participants in Tanner stage I. This result is in support of previous studies stating the importance of calcium intake and bone mineralization in the prepubertal stage, suggested by our findings, which yielded a positive correlation only in the prepubertal stage. One of the reasons for the same effect not being observed in puberty is thought to be due to the hormonal changes and active role of sex steroids. This shows how critical the prepubertal period is for future bone health. During this critical period of prepuberty, the significance of nutritions and physical activity is evident.

    Between-country comparisons of estimated dietary intake are particularly prone to error when different food composition tables are used. The objective of this study was to describe our procedures and rationale for the selection and adaptation of available food composition to a single database to enable cross-country nutritional intake comparisons. Latin American Study of Nutrition and Health (ELANS) is a multicenter cross-sectional study of representative samples from eight Latin American countries. A standard study protocol was designed to investigate dietary intake of 9000 participants enrolled. Two 24-h recalls using the Multiple Pass Method were applied among the individuals of all countries. Data from 24-h dietary recalls were entered into the Nutrition Data System for Research (NDS-R) program after a harmonization process between countries to include local foods and appropriately adapt the NDS-R database. A food matching standardized procedure involving nutritional equivalency of local food reported by the study participants with foods available in the NDS-R database was strictly conducted by each country. Standardization of food and nutrient assessments has the potential to minimize systematic and random errors in nutrient intake estimations in the ELANS project. This study is expected to result in a unique dataset for Latin America, enabling cross-country comparisons of energy, macro- and micro-nutrient intake within this region. PMID:26389952

    A 24 kcal/oz (81 kcal/100 ml) premature infant formula (Enfamil Premature Formula) with moderately high mineral content (117 mg Ca/100 ml and 58 mg P/100 ml) and a protein content of 3 g/100 kcal was evaluated in sixteen 3-day balance studies at 10 and 21 days of age in nine premature infants with birth weights from 1,200 to 1,400 g. Growth rates were similar to in utero rates, and the formula was well accepted and tolerated. Calcium retention (62.5%) was similar to in utero accretion, and phosphorus retention was only slightly lower. Nitrogen retention was high without the development of metabolic acidosis or abnormal serum urea nitrogen levels.

    The purpose of this research was to describe the context created by students as they worked in groups on a nutrition computer-assisted instruction (CAI) program. Students worked on the program in groups of three. Observational methods were used to collect data from students in two sixth-grade classrooms that were part of an experimental program designed to restructure the educational process. Thirty-two students, from 12 groups, were observed as they completed the program. The groups were assigned by the teachers according to standard principles of cooperative learning. Students completed "Ship to Shore," a program designed specifically for this research. The program required three to five 50-minute classroom periods to complete. The objectives of the program were to change children's knowledge structure of basic nutrition concepts and to increase children's critical thinking skills related to nutrition concepts. We collected observational data focused on three domains: (1) student-computer interaction, (2) student-student interaction, and (3) students' thinking and learning skills. Grounded theory methods were used to analyze the data. Specifically, the constant-comparative method was used to develop open coding categories, defined by properties and described by dimensions. The open coding categories were in turn used in axial coding to differentiate students' learning styles. Five styles of student interaction were defined. These included (1) dominant directors (n = 6; 19%), (2) passive actors (n = 5; 16%), (3) action-oriented students (n = 7; 22%), (4) content-oriented students (n = 8; 25%), and (5) problem solvers (n = 5; 16%). The "student style" groups were somewhat gender specific. The dominant directors and passive actors were girls and the action-oriented and content-oriented students were boys. The problem solvers group was mixed gender. Children's responses to computer-based nutrition education are highly variable. Based on the results of this research

    2003-05-01

    The present paper addresses the emergence and development of Nordic food and nutrition policies, with some reference to the types of nutrition policies characteristic of other North European countries. Nutrition programmes aimed at dietary change have a long history of public responsibility in several Nordic and North European countries. The extent of involvement, the orientation and (indication of) success have, however, varied considerably between countries. First, different types of policies are characterised by their choice of programmes and measures, e.g. information campaigns v. market regulation or catering and public services. Second, the distinctions are associated not only with programmes, but also with the status and validity of nutritional advice and dietary guidelines in public policy making. Third, when focusing on how and on what grounds the governments have developed nutrition policies, it is evident that while more or less the same participants and issues are involved, their roles and relationships may be different. In this case the role and involvement of nutritional expertise and scientific arguments in various countries will be discussed. Finally, nutrition policies may entail conflicts of interest, particularly when health concerns are confronted with food industry and agricultural interests. This situation is quite evident in the question of animal fat. The present paper addresses how these issues have been dealt with quite differently in various countries. PMID:14506905

    Nutritional therapy for cancer patients includes various objectives such as improvement of cachexia, elucidation of the mechanism of malnutrition, development of therapy for anorexia, nutrition support during chemotherapy or radiotherapy, and inhibition of tumor growth under controlled caloric intake. This review describes recent remarkable developments in nutritional therapy for cancer patients. Cytokines such as interleukin (IL)-1, IL-6, and tumor necrosis factor which induce proteolysis and lipolysis are involved in the cause of malnutrition and cachexia in cancer patients. IL-1 also plays a significant role in the development of cancer anorexia via direct action in the brain. For anorexia therapy, progestogens have been shown to improve appetite and food intake in cancer patients. Moreover, glutamine supplementation improves the host protein metabolism without enhancement of tumor growth during chemotherapy. Among the effects of caloric intake on anticancer therapy, AO-90, a methionine-free intravenous amino acid solution, has been shown to increase the antitumor effect of 5-fluorouracil in clinical studies. From these observations, recent progress in nutritional therapy for cancer patients has been remarkable. Further study of nutritional therapy is required in order to maintain or improve the quality of life of cancer patients in the future.

    Introduction Nutrition transition is occurring rapidly in the world, especially in developing countries. The nutrition transition occurred in Iran very fast due to urbanization and changes in the lifestyle of people, leading to overweight and obesity. However, nutritional deficiencies are still detected due to economic factors and low nutritional knowledge. Nutrition policies do not adequately respond to the nutrition challenges in Iran. This study was conducted to evaluate and analyze the nutrition policy process challenges in Iran. Methods A qualitative study using semi-structured interviews was conducted with 59 policy makers and nutrition experts of medical universities across Iran. Interviews were continued until data saturation was achieved. Data were supplemented with surveys and documentary analysis. Thematic analysis was guided by the propositions of the stages heuristic framework. Results The results were categorized into four main themes and eight sub-themes. The main themes were 1) nutrition problem definition, 2) policy formulation, 3) implementation of the policies, and 4) evaluation of the policies. However, the multi-faceted nature of the nutritional problem makes it difficult to deal with, so a multi-sectoral approach is needed. Conclusion Nutrition policies have been implemented in Iran with varying degrees of success and with different levels of cross-sectoral collaboration. The nutrition policies sometimes have not been able to respond to the nutritional problems. One of the important reasons is that nutrition is not a priority for policy makers. Many policies suffer from a lack of adequate and appropriate resource allocation. Cooperation mechanisms to resolve nutritional problems are sometimes ineffective and inefficient. PMID:27053992

    The purpose of this investigation was to develop, implement, and evaluate a theoretically based nutritional education intervention through a DVD lecture series (three 30-minute classes) in summer intensive programs for pre-professional, adolescent ballet dancers. Objectives of this intervention program were to increase knowledge of basic sports nutrition principles and the Female Athlete Triad and promote self-efficacy for adopting healthier dietary habits. Dancers ranging from 13 to 18 years old who were attending summer intensive programs affiliated with professional ballet companies were recruited. Group One (n = 231) participated in the nutrition education program, while Group Two the control participants (n = 90) did not. Assessments of the participants' dietary status consisted of a demographic questionnaire, a Sports Nutrition Knowledge and Behavior Questionnaire, and a Food Frequency Questionnaire. The intervention group was assessed at baseline, immediately post-program, and at six weeks post-program. The control group was assessed at baseline and at six weeks post-baseline. The intervention program was effective at increasing nutrition knowledge, perceived susceptibility to the Female Athlete Triad, and self-efficacy constructs. Improvements in dietary intake were also observed among intervention group participants. To improve overall health and performance nutrition education should be incorporated into the training regimens of adolescent dancers. This potentially replicable DVD-based program may be an effective, low-cost mechanism for doing that.

    2013-05-21

    This article examines two strands of discourse on wild capture fisheries; one that focuses on resource sustainability and environmental impacts, another related to food and nutrition security and human well-being. Available data and research show that, for countries most dependent on fish to meet the nutritional requirements of their population, wild capture fisheries remain the dominant supplier. Although, contrary to popular narratives, the sustainability of these fisheries is not always and everywhere in crisis, securing their sustainability is essential and requires considerable effort across a broad spectrum of fishery systems. An impediment to achieving this is that the current research and policy discourses on environmental sustainability of fisheries and food security remain only loosely and superficially linked. Overcoming this requires adoption of a broader sustainability science paradigm to help harness synergies and negotiate tradeoffs between food security, resource conservation, and macroeconomic development goals. The way society chooses to govern fisheries is, however, an ethical choice, not just a technical one, and we recommend adding an ethical dimension to sustainability science as applied to fisheries.

    Reducing the size of low-solubility iron (Fe)-containing compounds to nanoscale has the potential to improve their bioavailability. Because Fe and zinc (Zn) deficiencies often coexist in populations, combined Fe/Zn-containing nanostructured compounds may be useful for nutritional applications. Such compounds are developed here and their solubility in dilute acid, a reliable indicator of iron bioavailability in humans, and sensory qualities in sensitive food matrices are investigated. Phosphates and oxides of Fe and atomically mixed Fe/Zn-containing (primarily ZnFe2O4) nanostructured powders were produced by flame spray pyrolysis (FSP). Chemical composition and surface area were systematically controlled by varying precursor concentration and feed rate during powder synthesis to increase solubility to the level of ferrous sulfate at maximum Fe and Zn content. Solubility of the nanostructured compounds was dependent on their particle size and crystallinity. The new nanostructured powders produced minimal color changes when added to dairy products containing chocolate or fruit compared to the changes produced when ferrous sulfate or ferrous fumarate were added to these foods. Flame-made Fe- and Fe/Zn-containing nanostructured powders have solubilities comparable to ferrous and Zn sulfate but may produce fewer color changes when added to difficult-to-fortify foods. Thus, these powders are promising for food fortification and other nutritional applications.

    This article examines two strands of discourse on wild capture fisheries; one that focuses on resource sustainability and environmental impacts, another related to food and nutrition security and human well-being. Available data and research show that, for countries most dependent on fish to meet the nutritional requirements of their population, wild capture fisheries remain the dominant supplier. Although, contrary to popular narratives, the sustainability of these fisheries is not always and everywhere in crisis, securing their sustainability is essential and requires considerable effort across a broad spectrum of fishery systems. An impediment to achieving this is that the current research and policy discourses on environmental sustainability of fisheries and food security remain only loosely and superficially linked. Overcoming this requires adoption of a broader sustainability science paradigm to help harness synergies and negotiate tradeoffs between food security, resource conservation, and macroeconomic development goals. The way society chooses to govern fisheries is, however, an ethical choice, not just a technical one, and we recommend adding an ethical dimension to sustainability science as applied to fisheries.

    Bangladesh is one of the poorest countries of the world with the highest population density. The Bangladesh government recognizes the educational and financial benefits of early childhood development (ECD) and has incorporated ECD into the national plan of action. However, ECD activities are not fully established in the country and there have been few evaluations. In this paper, we present ECD programs that are integrated into health and nutrition services in Bangladesh. We present four evaluation reports of such programs and we also include seven published research projects showing evidence that such integrations are feasible. We provide short reviews on coverage, methodology, and effects of the published reports and share our experience of challenges faced and steps taken to solve them. Overall, very few programs are based on scientific evidence and fewer are even evaluated. The research projects so far conducted are promising and there is sufficient evidence on feasibility of integrating ECD activities into nutrition and health programs. Suggestions are made on measures to overcome the implementation problems and on suitable methods to establish high-quality ECD programs in Bangladesh and in other low- and middle-income countries.

  6. Parallels between nutrition and physical activity: research questions in development of peak bone mass.

    Lifestyle choices are attributed to 40% to 60% of adult peak bone mass. The National Osteoporosis Foundation (NOF) sought to update its 2000 consensus statement on peak bone mass and partnered with the American Society for Nutrition, which, in turn, charged a 9-member writing committee with using a systematic review approach to update the previous NOF guidelines. PubMed searches of the scientific literature from January 2000 through December 2014 were conducted on all relevant lifestyle choice factors and their relation to increasing bone mass during childhood and adolescence. The writing group concluded that there is strong evidence for the benefits of physical activity and calcium intake on bone mass accretion, moderately strong evidence for the benefits of vitamin D and dairy intake on bone mass and for physical activity on bone structure, and weaker evidence for other lifestyle choices. There were parallels and synergies between the benefits of diet and exercise on development of peak bone mass, but the type of evidence and public policy recommendations in the two disciplines differ in several important ways. Nutrition uses a more reductionist approach in contrast to physical activity, which uses a more global approach. This leads to differences in research priorities in the 2 disciplines. The disciplines can advance more quickly through collaboration and adoption of the best approaches from each other. PMID:25965111

    The fibroblast growth factor (FGF)-FGF receptor (FGFR) system plays a role in angiogenesis and maintenance of vascular integrity, but its potential role in adipose tissue related angiogenesis and development is still unknown. Administration of SSR, a low molecular weight inhibitor of multiple FGFRs, did not significantly affect body weight nor weight of subcutaneous or gonadal (GON) fat, as compared with pair-fed control mice. Adipocyte hypertrophy and reduced adipocyte density were only observed in GON adipose tissues of treated mice. Adipose tissue angiogenesis was not affected by SSR treatment, as normalized blood vessel density was comparable in adipose tissues of both groups. Blocking the FGF-FGFR system in vivo does not markedly affect adipose tissue development in mice with nutritionally induced obesity.

    The distinctive qualities of the cuisine of Hangzhou are the result of its geographical situation, which provided good soils, reliable rainfall, a lake that has been a water source and renowned beauty spot for centuries. The rich water-sources facilitated the development of gastronomy, agriculture, trade and administration, especially after it became the capital of the Southern Sung Dynasty. Hangzhou's food sources are especially diverse, notably for fish, green vegetables, fungi, and tofu, and have been since early records. As capital, it became a leader in cuisine, and in the development of the restaurant industry. The strength of food traditions has been reinforced constantly by the cultural, medicinal, nutritional, and social values of food and cooking, by the interest of Chinese scholars in food and wine, and by the narrative that accompanies specific dishes.

    Intramuscular fat (IMF) content plays a key role in various quality traits of meat. IMF content varies between species, between breeds and between muscle types in the same breed. Other factors are involved in the variation of IMF content in animals, including gender, age and feeding. Variability in IMF content is mainly linked to the number and size of intramuscular adipocytes. The accretion rate of IMF depends on the muscle growth rate. For instance, animals having a high muscularity with a high glycolytic activity display a reduced development of IMF. This suggests that muscle cells and adipocytes interplay during growth. In addition, early events that influence adipogenesis inside the muscle (i.e proliferation and differentiation of adipose cells, the connective structure embedding adipocytes) might be involved in interindividual differences in IMF content. Increasing muscularity will also dilute the final fat content of muscle. At the metabolic level, IMF content results from the balance between uptake, synthesis and degradation of triacylglycerols, which involve many metabolic pathways in both adipocytes and myofibres. Various experiments revealed an association between IMF level and the muscle content in adipocyte-type fatty acid-binding protein, the activities of oxidative enzymes, or the delta-6-desaturase level; however, other studies failed to confirm such relationships. This might be due to the importance of fatty acid fluxes that is likely to be responsible for variability in IMF content during the postnatal period rather than the control of one single pathway. This is evident in the muscle of most fish species in which triacylglycerol synthesis is almost zero. Genetic approaches for increasing IMF have been focused on live animal ultrasound to derive estimated breeding values. More recently, efforts have concentrated on discovering DNA markers that change the distribution of fat in the body (i.e. towards IMF at the expense of the carcass fatness

    Nutrition programs that target English-as-Second-Language (ESL) students can potentially improve their nutrition knowledge. This pilot study evaluated the effect of a Food Guide Pyramid (FGP) lesson on nutrition knowledge of ESL students (ages 9-12 years) in a refugee after-school program. A pre- and post-FGP lesson one group design was used. A 12-item knowledge questionnaire was administered to students (N = 15) and their opinions about the lesson were obtained. Overall FGP lesson mean knowledge scores did not increase significantly from pretest to posttest; however, scores that measured specific objectives on the ability to identify food groups and the number of servings for food groups increased, while scores on the ability to identify the importance of each food group for health decreased. Overall, students liked the nutrition lesson, described learning mainly about the FGP, and reported no confusing aspects. Findings suggest that nutrition education targeted to ESL students should emphasize foods versus nutrients and promote active learner involvement. PMID:19835000

    Gilthead seabream and European sea bass are two of the most commonly farmed fish species. Larval development is critical to ensure high survival rates and thus avoid unacceptable economic losses, while nutrition and immunity are also important factors. For this reason this paper evaluates the ontogenetic development of seabream and sea bass digestive and immune systems from eggs to 73 days post-fertilisation (dpf) by assessing the expression levels of some nutrition-relevant (tryp, amya, alp and pept1) and immune-relevant (il1b, il6, il8, tnfa, cox2, casp1, tf, nccrp1, ighm and ight) genes. The results point to similar ontogenetic development trends for both species as regard nutrition and differences in some immunity related genes.

    Acceleration of progress in nutrition will require effective, large-scale nutrition-sensitive programmes that address key underlying determinants of nutrition and enhance the coverage and effectiveness of nutrition-specific interventions. We reviewed evidence of nutritional effects of programmes in four sectors--agriculture, social safety nets, early child development, and schooling. The need for investments to boost agricultural production, keep prices low, and increase incomes is undisputable; targeted agricultural programmes can complement these investments by supporting livelihoods, enhancing access to diverse diets in poor populations, and fostering women's empowerment. However, evidence of the nutritional effect of agricultural programmes is inconclusive--except for vitamin A from biofortification of orange sweet potatoes--largely because of poor quality evaluations. Social safety nets currently provide cash or food transfers to a billion poor people and victims of shocks (eg, natural disasters). Individual studies show some effects on younger children exposed for longer durations, but weaknesses in nutrition goals and actions, and poor service quality probably explain the scarcity of overall nutritional benefits. Combined early child development and nutrition interventions show promising additive or synergistic effects on child development--and in some cases nutrition--and could lead to substantial gains in cost, efficiency, and effectiveness, but these programmes have yet to be tested at scale. Parental schooling is strongly associated with child nutrition, and the effectiveness of emerging school nutrition education programmes needs to be tested. Many of the programmes reviewed were not originally designed to improve nutrition yet have great potential to do so. Ways to enhance programme nutrition-sensitivity include: improve targeting; use conditions to stimulate participation; strengthen nutrition goals and actions; and optimise women's nutrition, time

The primary aim of this paper is to summarize the findings from two recent cluster randomized controlled trials (Wise Mind and LA Health) that tested the hypothesis that modification of school cafeteria environments, including changes in nutrition standards, would yield beneficial changes in childhood nutrition and healthy eating in the school lunch environment. A secondary aim was to investigate the association of participant characteristics and changes in nutrition and healthy eating. A third aim was to investigate the relationships between the food intake of children and: (1) foods selected by the children and (2) food that was uneaten during the lunch meal (plate waste). The studies used similar approaches for modifying the school cafeteria environment and both studies used the digital photography method to measure changes in food intake, food selection, and plate waste. Both studies reported significant improvements in childhood nutrition, and the LA Health study reported improved healthy eating, following introduction of the cafeteria modification program in comparison to baseline and/or control arms. These studies confirm the hypothesis that interventions that modify the school cafeteria environment can beneficially impact childhood nutrition. PMID:23154216

    Cookin' Up Health is a culturally targeted and individualized tailored nutrition intervention using a computer-based interactive format. Using a cooking show theme, the program demonstrates step-by-step meal preparation emphasizing healthy selection and portion control. Focus groups were conducted with women in two rural counties in West Virginia to guide the development of the intervention. Women felt more susceptible to heart disease because the changing role of women creates more stress and less time; weight loss was a greater motivator for dietary change than was preventing heart disease; social support is a barrier and facilitator for dietary change; cultural heritage and the way women were raised were major barriers to making health changes as adults; convenience and the cost of eating healthier were major factors when trying to make changes in diet; and women did not feel confident in their ability to maintain dietary changes.

    In order to evaluate the effect of nutritional education on the risk of developing lifestyle-related diseases, we measured taurine and isoflavone content in 24-hour urine samples (24-U) of 3rd grade Chinese children (CC) and of age-matched Japanese children (JC), as well as adult Chinese and Japanese (CA, JA) according to the WHO-CARDIAC (Cardiovascular Diseases and Alimentary Comparison) Study protocol. There was a significantly higher prevalence of obesity and "thin" individuals in CC compared with JC. While K intake was not significantly different in the children, the sodium to potassium ratio (Na/ K) and the intake of sodium chloride (NaCl) were significantly higher in CC than in JC. Taurine excretion (24-U) was significantly higher in CC than in JC, but isoflavone excretion was significantly lower in CC than in JC. Taurine excretion was significantly lower in CA than in JA, while isoflavone excretion was almost the same in CA and JA. After nutritional education CC consumed more isoflavones than the control group that had been subjected to only environmental education. JC exhibited significantly higher 24-U taurine and isoflavone excretion after taking the nutritional class.

  6. Development of tuberous roots and sugar accumulation as related to invertase activity and mineral nutrition.

    PubMed

    Sucrose storage in tuberous roots was not observed when the tissues had very high activities of acid invertase. High activities of the enzyme were always present in the roots at early stages of their development. In species where the activity of the enzyme decreased during root development, sucrose was stored. Thus, acid invertase was undetectable in mature roots of carrots (Daucus carota L.) where sucrose formed almost 80% of the dry matter. Conversely, radish (Raphanus sativus L.) and turnip (Brassica rapa L.) roots, in which the activity of the enzyme remained high until maturity, did not store appreciable amounts of sucrose (2% and 9%, respectively, of the dry matter in the mature roots), reducing sugars being the main reserve (more than 80% of the dry matter in mature turnips). The correlation between sucrose content and acid invertase activity was furthermore evident in both sucrose- and hexose-storing roots when the activity of this enzyme was affected by changes in the mineral nutrition. Deficiencies of nitrogen and sulphur reduced the activity of acid and alkaline invertases and led to increase in sucrose content and decrease in reducing sugars. However, the decline of alkaline invertase activity in tissues low in acid invertase had no clear effect on sugar content. Sodium chloride (10(-1)M) affected acid invertase and sugars in a manner similar to that of the two deficiencies, but had practically no effect on alkaline invertase. The changes in sugar content produced by the variations in mineral nutrition were small in hexose-storing roots in relation to those of sucrose-storing roots. It is possible that this result is related to the different levels of acid invertase in the two types of roots.

    This study examines the performance of dietitians-in-training on developing a diet plan for a diabetic patient either independently or after peer discussion. Participants (n = 58) from an undergraduate program in food and nutrition were divided into two groups based on their prior knowledge before being randomly assigned into three conditions: (1) peer discussion with just-in-time information (JIT information), (2) peer discussion without JIT information), and (3) independent performers. The learners' performance in the three conditions was analyzed. The results presented here describe the role of prior knowledge and JIT information across the conditions and the interaction of the two factors as well as the instructional implications of the findings.

    Optimal nutrition will be critical for crew members who embark on space exploration missions. Nutritional assessment provides an opportunity to ensure that crewmembers begin their missions in optimal nutritional status, to document changes during a mission and, if necessary, to provide intervention to maintain that status throughout the mission, and to assesses changes after landing in order to facilitate the return to their normal status as soon as possible after landing. We report here the findings from our nutritional assessment of astronauts who participated in the International Space Station (ISS) missions, along with flight and ground-based research findings. We also present ongoing and planned nutrition research activities. These studies provide evidence that bone loss, compromised vitamin status, and oxidative damage are the critical nutritional concerns for space travelers. Other nutrient issues exist, including concerns about the stability of nutrients in the food system, which are exposed to longterm storage and radiation during flight. Defining nutrient requirements, and being able to provide and maintain those nutrients on exploration missions, will be critical for maintaining crew member health.

    The adequate dietary intake is important to maintain the nutritional status of the patients after pancreatic cancer surgery. This prospective study was designed to investigate the dietary intake and the nutritional status of the patients who had pancreatic cancer surgery. Thirty-one patients (15 men, 16 women) were enrolled and measured body weight, body mass index (BMI), nutritional risk index (NRI), and Malnutrition Universal Screening Tool (MUST). Actual oral intake with nutritional impact symptoms recorded on the clinical research foam at every meal and medical information were collected from electronic medical charts. The rates of malnutrition at admission were 45.1% (14/31) and 28.9% (9/31) by NRI and MUST method, respectively, but those were increased to 87% (27/31) and 86.6% (26/31) after operation on discharge. The median values of daily intake of energy, carbohydrates, fat, and protein were 588.1 kcal, 96.0 g, 11.8 g, and 27.0 g, respectively. Most patients (n = 20, 64.5%) experienced two or more symptoms such as anorexia, abdominal bloating and early satiety. There were negative correlations between C-reactive protein (CRP) levels and the intake of total energy, protein, fat, and zinc. The rates of malnutrition were increased sharply after surgery and the dietary intake also influenced the inflammatory indicators. The results suggested that need of considering special therapeutic diets for the patients who received pancreatic surgery. PMID:27812517

  10. Impact of foods nutritionally enhanced through biotechnology in alleviating malnutrition in developing countries.

    According to United Nations (UN) projections, the world's population will grow from 6.1 billion in 2000 to 8 billion in 2025 and 9.4 billion in 2050. Most (93%) of the increase will take place in developing countries. The rapid population growth in developing countries creates major challenges for governments regarding food and nutrition security. According to current World Health Organization estimates, more than 3 billion people worldwide, especially in developing countries, are malnourished in essential nutrients. Malnutrition imposes severe costs on a country's population due to impaired physical and cognitive abilities and reduced ability to work. Little progress has been made in improving malnutrition over the past few decades. The Food and Agriculture Organization of the UN would like to see more nutrient-rich foods introduced into these countries, because supplements are expensive and difficult to distribute widely. Biofortification of staple crops through modern biotechnology can potentially help in alleviating malnutrition in developing countries. Several genetically modified crops, including rice, potatoes, oilseeds, and cassava, with elevated levels of essential nutrients (such as vitamin A, iron, zinc, protein and essential amino acids, and essential fatty acids); reduced levels of antinutritional factors (such as cyanogens, phytates, and glycoalkaloid); and increased levels of factors that influence bioavailability and utilization of essential nutrients (such as cysteine residues) are advancing through field trial stage and regulatory processes towards commercialization. The ready availability and consumption of the biofortified crops would have a significant impact in reducing malnutrition and the risk of chronic disease in developing countries.

    This Comment by the Committee on Nutrition of the European Society for Paediatric Gastroenterology, Hepatology, and Nutrition aims to provide a summary of the role of nutrition-related factors on obesity prevention in children ages 2 to 18 years. This Comment emphasizes that dietary interventions should be incorporated into a multidisciplinary strategy for obesity prevention. No single nutrient has been unequivocally associated with the development of obesity. Methodological limitations in study design and the complex nature of obesity must be taken into account when interpreting the association with reported dietary factors. Energy intake should be individually determined, taking into account energy expenditure and growth. Preferential intake of slowly absorbed carbohydrates and limiting the ingestion of rapidly absorbed carbohydrates and simple sugars should be promoted. No specific recommendations for macronutrient intakes to prevent obesity can be made. Plant foods can be used as the main food contributors to a well-balanced diet with adequate monitoring of nutrient intake. Plain water should be promoted as the main source of fluids for children instead of sugar-sweetened beverages. Children should eat at least 4 meals, including breakfast, every day. Regular family meals should be encouraged. Regular consumption of fast food with large portion sizes and high energy density should be avoided. Healthy food options should be promoted for snacking. Food portion sizes should be appropriate for age and body size. Nutrition and lifestyle education aimed at the prevention of obesity should be included in the routine care of children by health care professionals.

    2012-01-01

    Background Information about behavior of energy intake in ultra-endurance cyclists during a 24-hour team relay race is scarce. The nutritional strategy during such an event is an important factor which athletes should plan carefully before the race. The purpose of this study was to examine and compare the nutritional intake of ultra-endurance cyclists during a 24-hour team relay race with the current nutritional guidelines for endurance events. Additionally, we analyzed the relationship among the nutritional and performance variables. Methods Using a observational design, nutritional intake of eight males (mean ± SD: 36.7 ± 4.7 years; 71.6 ± 4.9 kg; 174.6 ± 7.3 cm; BMI 23.5 ± 0.5 kg/m2) participating in a 24-hour team relay cycling race was assessed. All food and fluid intake by athletes were weighed and recorded. Additionally, distance and speed performed by each rider were also recorded. Furthermore, before to the race, all subjects carried out an incremental exercise test to determine two heart rate-VO2 regression equations which were used to estimate the energy expenditure. Results The mean ingestion of macronutrients during the event was 943 ± 245 g (13.1 ± 4.0 g/kg) of carbohydrates, 174 ± 146 g (2.4 ± 1.9 g/kg) of proteins and 107 ± 56 g (1.5 ± 0.7 g/kg) of lipids, respectively. This amount of nutrients reported an average nutrient intake of 22.8 ± 8.9 MJ which were significantly lower compared with energy expenditure 42.9 ± 6.8 MJ (P = 0.012). Average fluid consumption corresponded to 10497 ± 2654 mL. Mean caffeine ingestion was 142 ± 76 mg. Additionally, there was no relationship between the main nutritional variables (i.e. energy intake, carbohydrates, proteins, fluids and caffeine ingestion) and the main performance variables (i.e. distance and speed). Conclusions A 24-hour hours cycling competition in a team relay format elicited high energy demands which were not compensated by energy intake of the athletes despite that dietary

    In the recent years there has been a proliferation of initiatives to classify food products according to their nutritional composition (e.g., high in fat/sugar) to better guide consumer choices and regulate the food environment. This global trend, lately introduced in Asia as well, utilizes nutrient profiling (NP) to set compositional criteria for food products. Even though the use of NP to set targets for product reformulation has been proposed for years, to date only two NP systems have been specifically developed for that purpose. The majority of the NP applications, especially in Asia, focus on marketing and/or health claim regulation, as well as front-of-pack labeling. Product reformulation has been identified, by the World Health Organization and other official bodies, as a key tool for the food industry to help address public health nutrition priorities and provide support towards the reduction of excessive dietary sugar, salt and fats. In the United Kingdom, the Responsibility Deal is an excellent example of a public-private collaborative initiative that successfully reduced the salt content of products available in the supermarkets by 20-30%, resulting in an estimated 10% reduction in salt intake at the population level. Validation of NP systems targeted towards reformulation supports the hypothesis that, by adopting them, the industry can actively support existing policies in the direction of lowering consumptions in public health-sensitive nutrients. The symposium presented a discussion on the current NP landscape in Asia, the importance of reformulation for public health and the Nestlé approach to improve the food environment in Asia through NP.

    There is scarce research and programmatic evidence on the effect of poor water, sanitation, and hygiene (WASH) conditions of the physical environment on early child cognitive, sensorimotor, and socioemotional development. Furthermore, many common WASH interventions are not specifically designed to protect babies in the first 3 years of life, when gut health and linear growth are established. We review evidence linking WASH, anemia, and child growth, and highlight pathways through which WASH may affect early child development, primarily through inflammation, stunting, and anemia. Environmental enteropathy, a prevalent subclinical condition of the gut, may be a key mediating pathway linking poor hygiene to developmental deficits. Current early child development research and programs lack evidence-based interventions to provide a clean play and infant feeding environment in addition to established priorities of nutrition, stimulation, and child protection. Solutions to this problem will require appropriate behavior change and technologies that are adapted to the social and physical context and conducive to infant play and socialization. We propose the concept of baby WASH as an additional component of early childhood development programs.

    A comprehensive search of the literature for studies examining physical activity or nutrition interventions in the workplace, published between 1999 and March 2009, was conducted. This search identified 29 relevant studies. Interventions were grouped according to the theoretical framework on which the interventions were based (e.g. education, cognitive-behavioural, motivation enhancement, social influence, exercise). Weighted Cohen's d effect sizes, percentage overlap statistics, confidence intervals and fail safe Ns were calculated. Most theoretical approaches were associated with small effects. However, large effects were found for some measures of interventions using motivation enhancement. Effect sizes were larger for studies focusing on one health behaviour and for randomized controlled trials. The workplace is a suitable environment for making modest changes in the physical activity, nutrition and health of employees. Further research is necessary to determine whether these changes can be maintained in the long term.

    A statewide professional development program was developed and implemented throughout California for school nutrition directors with the goal of creating healthy school environments and regional networks for collaboration and healthy school environment sustainability. Needs of school nutrition directors were identified through a needs assessment questionnaire. Results of the needs assessment questionnaire (n = 256) identified (a) planning cost-effective menus; (b) reducing calories, sodium, saturated fat, and trans fat in menus; and (c) using U.S. Department of Agriculture foods cost-effectively as the most useful topics. Highest rated topics informed the content of the professional development program. A post-professional development questionnaire identified key "insights, inspirations, and strategies" as (a) marketing of school foods program, (b) expansion of salad bars, and (c) collaboration with community partners. A 6-month follow-up questionnaire identified that 86% of participants made progress toward implementing at least one of their five insights, inspirations, and strategies in their school districts. Most common areas that were implemented were marketing and branding (32%), revamping salad bars (18%), and motivating staff (16%). School and Community Actions for Nutrition survey analysis showed a significant increase in the use of marketing methods in school nutrition programs from baseline to 6-month post-program implementation (p = .024).

  7. Nutritional status in peritoneal dialysis: studies in body composition, lipoprotein metabolism and peritoneal function.

    PubMed

    Johansson, Ann-Cathrine

    2002-01-01

    This thesis is based on clinical studies including virtually all patients treated with peritoneal dialysis in Gothenburg during the 1990s. The patients had a fundamentally altered body composition compared to healthy subjects, characterised by a reduction in body cell mass and body fat already at start of dialysis. During PD treatment. a further decrease in body cell mass was observed. Energy stores tended to normalise during the first years of treatment and remained constant thereafter, or declined subsequently. Extracellular water, calculated from the four-compartment model, was increased when patients started PD treatment and increased further, in parallel to the reduction in body cell mass. These alterations were seen in combination with a normal. or slightly reduced, body weight. Standard methods of assessing nutritional status may therefore not be valid in the dialysis population. Prediction equations to estimate total body water, used in measurements of dialysis adequacy, give erroneous results in PD patients, as shown in a study on our PD population. This may have important clinical consequences, especially in wasted patients. Reduced muscle mass is a marker of protein-energy malnutrition, and therefore simple and reliable methods to measure muscle mass are warranted. When lean body mass was calculated from creatinine generation rate and compared to lean body mass estimated from measurements of total body potassium. the agreement between the two methods was low. Furthermore, when repeated measurements of creatinine generation rate were performed, the variation coefficient was unacceptably high. Thus. creatinine generation rate cannot be recommended as a method to evaluate somatic protein status in PD patients. The lipoprotein metabolic derangements are pronounced in PD patients. in which a further increase in cholesterol and cholesterol-rich apoB-containing lipoproteins are added to the already pre-existing renal dyslipidemia. characterised by increased

    School nutrition policies limiting access to sweetened beverages, candy, and salty snacks have the potential to improve the health of children. To effectively evaluate policy success, appropriate and validated dietary assessment instruments are needed. The objective of this study was to develop and validate a beverage and snack questionnaire suitable for use among young adolescents. A new 19-item Beverage and Snack Questionnaire (BSQ) was administered to middle school students on two occasions, 2 weeks apart, to measure test-retest reliability. The questionnaire inquired about frequency of consumption, both at school and away from school, of soft drinks, salty snacks, sweets, milk, and fruits and vegetables. Students also completed 4-day food records. To assess validity, food-record data were compared with BSQ data. Forty-six students of diverse backgrounds from metropolitan Seattle, WA, participated in this study. Participants answered the BSQ during class time and completed the food record at home. Pearson correlation coefficients assessed test-retest reliability and validity. Using frequency per week data, the test-retest reliability coefficients were r=0.85 for fruits and vegetables consumed at school and r=0.74 and r=0.72 for beverages and sweets/snacks, respectively, consumed at school. Correlations ranged from r=0.73 to 0.77 for foods consumed outside of school. Compared with the criterion food record, validity coefficients were very good: r=0.69 to 0.71 for foods consumed at school and r=0.63 to 0.70 for foods consumed away from school. The validity coefficients for the 19 individual food items ranged from r=0.56 to 0.87. This easy-to-administer 19-item questionnaire captures data on sugar-sweetened beverages, salty snacks, sweets, milk, and fruit and vegetables as well as a more lengthy and expensive food record does. The BSQ can be used by nutrition researchers and practitioners to accurately evaluate student consumption of foods that are the focus of

    As part of a comprehensive programme to prevent non-communicable disease in South Africa, there is a need to develop public education campaigns on healthy eating. Urban populations of lower socioeconomic status are a priority target population. This study involved formative research to guide the development of a nutrition resource appropriate to the budgetary constraints and information needs of poor households in the major urban centres of South Africa. Twenty-two focus groups were convened to explore the target audience's knowledge, beliefs, attitudes and practices as they related to healthy eating and their views about the proposed nutrition resource (N = 167). A brief questionnaire assessed eating and cooking practices among focus group participants. Key informant interviews with eight dieticians/nutritionists working with this population added to the focus group findings. The research identified important issues to take into account in the development of the resource. These included the need to: directly address prevalent misconceptions about healthy eating and unhealthy eating practices; increase self-efficacy regarding the purchasing and preparation of healthy food; represent diverse cultural traditions and consider the issues of affordability and availability of food ingredients. This study demonstrates the value of using formative research in the design of nutrition-related communication in a multicultural, poor, urban South African setting. PMID:26590241

    1997-10-01

    In patients with acute pancreatitis or an acute flare of chronic pancreatitis, a discrepancy exists between increased protein/calorie requirements induced by a hypermetabolic stress state and reduced ingestion/assimilation of exogenous nutrients, which promotes progressive nutritional deterioration. Patients with severe pancreatitis (defined by > or =3 Ranson criteria, an APACHE II score of > or =10, development of major organ failure, and/or presence of pancreatic necrosis) are more likely to require aggressive nutritional support than patients with mild disease. The type of formula and level of the gastrointestinal tract into which nutrients are infused determine the degree to which pancreatic exocrine secretion is stimulated. Animal studies and early prospective randomized controlled trials in humans suggest that total enteral nutrition via jejunal feeding may be the preferred route to parenteral alimentation in this disease setting.

    2015-01-01

    Obesity, diabetes, and related metabolic disorders are major health issues worldwide. As the epidemic of metabolic disorders continues, the associated medical comorbidities, including the detrimental impact on reproduction, increase as well. Emerging evidence suggests that the effects of maternal nutrition on reproductive outcomes are likely to be mediated, at least in part, by oocyte metabolism. Well-balanced and timed energy metabolism is critical for optimal development of oocytes. To date, much of our understanding of oocyte metabolism comes from the effects of extrinsic nutrients on oocyte maturation. In contrast, intrinsic regulation of oocyte development by metabolic enzymes, intracellular mediators, and transport systems is less characterized. Specifically, decreased acid transport proteins levels, increased glucose/lipid content and elevated reactive oxygen species in oocytes have been implicated in meiotic defects, organelle dysfunction and epigenetic alteration. Therefore, metabolic disturbances in oocytes may contribute to the diminished reproductive potential experienced by women with metabolic disorders. In-depth research is needed to further explore the underlying mechanisms. This review also discusses several approaches for metabolic analysis. Metabolomic profiling of oocytes, the surrounding granulosa cells, and follicular fluid will uncover the metabolic networks regulating oocyte development, potentially leading to the identification of oocyte quality markers and prevention of reproductive disease and poor outcomes in offspring.

    Grocery sales are a data source of potential value to dietary assessment programs in public health informatics. However, the lack of a computable method for mapping between nutrient and food item information represents a major obstacle. We studied the feasibility of linking point-of-sale data to USDA-SR nutrient database information in a sustainable way. We analyzed 2,009,533 de-identified sales items purchased by 32,785 customers over a two-week period. We developed a method using the item category hierarchy in the supermarket’s database to link purchased items to records from the USDA-SR. We describe our methodology and its rationale and limitations. Approximately 70% of all items were mapped and linked to the SR; approximately 90% of all items could be mapped with an equivalent expenditure of additional effort. 100% of all items were mapped to USDA standard food groups. We conclude that mapping grocery sales data to nutritional information is feasible. PMID:22195115

    The study sought to ascertain and describe the physical and mental health states of Afghan refugee children after the terrorist attack on September 11, 2001 in the US and the aerial bombing of Afghanistan that followed. A cross-sectional survey was carried out in four refugee camps in Peshawar, Pakistan from February to March 2002, and comparisons among camps were made. A total of 70 males (mean age SD = 9.81 +/- 1.98 years old) and 30 females (7.94 +/- 2.07) answered a self-developed questionnaire on demographic data, traumatic events experience, living environment in the camps, and physical and mental health, through interviews. Anthropometric measures were measured and physical symptoms including anaemia and edema were assessed. Severe malnutrition was not shown and there were no significant differences in most nutritional and physical states among the camps. Nevertheless, in the newer camps more children experienced war related traumatic events. Mental symptoms were prevalent in all camps, though the characteristics of the symptoms differed among the camps. PMID:16425652

We studied the feasibility of linking point-of-sale data to USDA-SR nutrient database information in a sustainable way. We analyzed 2,009,533 de-identified sales items purchased by 32,785 customers over a two-week period. We developed a method using the item category hierarchy in the supermarket's database to link purchased items to records from the USDA-SR. We describe our methodology and its rationale and limitations. Approximately 70% of all items were mapped and linked to the SR; approximately 90% of all items could be mapped with an equivalent expenditure of additional effort. 100% of all items were mapped to USDA standard food groups. We conclude that mapping grocery sales data to nutritional information is feasible.

  17. Nutritional Status and Liver Transplantation

    Chronic liver disease has a profound effect on nutritional status and undernourishment is almost universally present in patients with end-stage liver disease undergoing liver transplantation. In the last decades, due to epidemiological changes, a trend showing an increase in patients with end-stage liver disease and associated obesity has also been reported in developed countries. Nutrition abnormalities may influence the outcome after transplantation therefore, the importance to carefully assess the nutritional status in the work-up of patients candidates for liver transplantation is widely accepted. More attention has been given to malnourished patients as they represent the greater number. The subjective global nutritional assessment and anthropometric measurements are recognized in current guidelines to be adequate in identifying those patients at risk of malnutrition. Cirrhotic patients with a depletion in lean body mass and fat deposits have an increased surgical risk and malnutrition may impact on morbidity, mortality and costs in the post-transplantation setting. For this reason an adequate calorie and protein intake should always be ensured to malnourished cirrhotic patient either through the diet, or using oral nutritional supplements or by enteral or parenteral nutrition although studies supporting the efficacy of nutritional supplementation in improving the clinical outcomes after transplantation are still scarce. When liver function is restored, an amelioration in the nutritional status is expected. After liver transplantation in fact dietary intake rapidly normalizes and fat mass is progressively regained while the recovery of muscle mass can be slower. In some patients unregulated weight gain may lead to over-nutrition and may favor metabolic disorders (hypertension, hyperglycemia, hyperlipidemia). This condition, defined as ‘metabolic syndrome’, may play a negative role on the overall survival of liver transplant patients. In this report we

    This article aimed at understanding nutritional knowledge, attitudes, and behaviors of homosexual persons living with HIV/AIDS in Chongqing, China. A cross sectional design using a valid and reliable survey was used. The survey was completed in Chongqing, Southwest China (n = 172). Knowledge of nutrition was deficient regarding sources of nutrients such as calcium and iron, relationships between diet/nutrients and disease, and only 36.1% of participants knew about the Balanced Diet Pagoda for Chinese. Eating habits did not meet the nutritional requirements, and a majority (59.3%) did not eat breakfast every day. The average score on the knowledge quiz was 51.8%. This study showed that homosexual persons with HIV/AIDS in China longed for nutrition knowledge, and this was supported by objective data. Efforts and targeted education programs aiming to improve their nutrition knowledge, attitudes, and behaviors need to be emphasized.

    This case study, in a Veterans Affairs Alzheimer's unit, was conducted to evaluate noise and lighting conditions at mealtimes and to assess the food intake of ambulatory dementia residents. The case study compared the noise, lighting, and nutritional intake of 16 Alzheimer's residents eating the same cycle menu in the extended-care (EC) dining room and the Alzheimer's unit (AU) dining room five weeks later. Noise was significantly lower in the EC (p < or = .02). Lighting was significantly higher in the EC (p < or = .001). Intake of calories and protein was slightly higher, with some days significantly higher, in the AU. Total five-day fluid intake at breakfast was significantly higher in the AU (p < or = .02). Although residents' total food and fluid intake was higher in the AU, the project identified a need to decrease noise and increase lighting in the AU. Lighting enhancement and noise reduction may further improve intake, which, in turn, may promote improved nutritional status.

    Over the past decade, our research group has characterized and used a mouse model to demonstrate that “nutritional programming” of bone development occurs when mice receive soy isoflavones (ISO) during the first days of life. Nutritional programming of bone development can be defined as the ability for diet during early life to set a trajectory for better or compromised bone health at adulthood. We have shown that CD-1 mice exposed to soy ISO during early neonatal life have higher bone mineral density (BMD) and greater trabecular inter-connectivity in long bones and lumbar spine at young adulthood. These skeletal sites also withstand greater forces before fracture. Because the chemical structure of ISO resembles that of 17-β-estradiol and can bind to estrogen receptors in reproductive tissues, it was prudent to expand analyses to include measures of reproductive health. This review highlights aspects of our studies in CD-1 mice to understand the early life programming effects of soy ISO on bone and reproductive health. Preclinical mouse models can provide useful data to help develop and guide the design of studies in human cohorts, which may, depending on findings and considerations of safety, lead to dietary interventions that optimize bone health.

    Samples of white and brown bread, both sliced and unsliced, and of wheatgerm breads and wholemeal bread were purchased in London and analysed for a wide range of nutrients. Available carbohydrate, dietary fibre, fatty acids, riboflavin, vitamin B6, and iodine were determined in bulked samples of each type of bread and, in addition, every loaf was analysed for moisture, fat, protein, phosphorus, chloride, sodium, potassium, calcium, magnesium, iron, zinc, copper, manganese, thiamin, nicotinic acid, and free and total folic acid, in order to provide an estimate the variability within each kind of bread. Virtually all the constituents that were measured in the individual loaves showed inter-loaf variation--particularly moisture contents and the levels of calcium, copper and folic acid. Unsliced loaves were more variable than sliced loaves but when expressed on a dry matter basis there were no significant differences in the nutrient levels in sliced and unsliced breads. Wheatgerm breads were relatively more homogenous products but wholemeal loaves were very unhomogenous reflecting the difficulty of accurately identifying unwrapped wholemeal loaves in retail outlets. Some differences from previously published values for all breads were found for dietary fibre, iron, thiamin and vitamin B6. Experience of sampling at retail outlets and analysis provided by this study will be integrated into the design of a planned study of breads throughout Britain.

    Background In light of its epidemic proportions in developed and developing countries, obesity is considered a serious public health issue. In order to increase knowledge concerning the ability of health care professionals in caring for obese adolescents and adopt more efficient preventive and control measures, a questionnaire was developed and validated to assess non-dietitian health professionals regarding their Knowledge of Nutrition in Obese Adolescents (KNOA). Methods The development and evaluation of a questionnaire to assess the knowledge of primary care practitioners with respect to nutrition in obese adolescents was carried out in five phases, as follows: 1) definition of study dimensions 2) development of 42 questions and preliminary evaluation of the questionnaire by a panel of experts; 3) characterization and selection of primary care practitioners (35 dietitians and 265 non-dietitians) and measurement of questionnaire criteria by contrasting the responses of dietitians and non-dietitians; 4) reliability assessment by question exclusion based on item difficulty (too easy and too difficult for non-dietitian practitioners), item discrimination, internal consistency and reproducibility index determination; and 5) scoring the completed questionnaires. Results Dietitians obtained higher scores than non-dietitians (Mann–Whitney U test, P < 0.05), confirming the validity of the questionnaire criteria. Items were discriminated by correlating the score for each item with the total score, using a minimum of 0.2 as a correlation coefficient cutoff value. Item difficulty was controlled by excluding questions answered correctly by more than 90% of the non-dietitian subjects (too easy) or by less than 10% of them (too difficult). The final questionnaire contained 26 of the original 42 questions, increasing Cronbach’s α value from 0.788 to 0.807. Test-retest agreement between respondents was classified as good to very good (Kappa test, >0.60). Conclusion The

    The benefits of early enteral feeding (EEN) have been demonstrated in gastrointestinal surgery. But, the impact of EEN has not been elucidated yet. We assessed the postoperative nutritional status of patients who had undergone pancreaticoduodenectomy (PD) according to the postoperative nutritional method and compared the clinical outcomes of two methods. A prospective randomized trial was undertaken following PD. Patients were randomly divided into two groups; the EEN group received the postoperative enteral feed and the control group received the postoperative total parenteral nutrition (TPN) management. Thirty-eight patients were included in our analyses. The first day of bowel movement and time to take a normal soft diet was significantly shorter in EEN group than in TPN group. Prealbumin and transferrin were significantly reduced on post-operative day (POD) 7 and were slowly recovered until POD 90 in the TPN group than in the EEN group. EEN group rapidly recovered weight after POD 21 whereas it was gradually decreased in TPN group until POD 90. EEN after PD is associated with preservation of weight compared with TPN and impact on recovery of digestive function after PD. PMID:22379336

    No nutrition literacy instruments have been tested in breast cancer survivors, yet nutrition is a critical lifestyle factor for optimizing weight and improving quality of life in breast cancer survival. Our objectives were to adapt our Nutrition Literacy Assessment Instrument for breast cancer populations and to pilot test its validity and reliability. We modified the instrument based on review by content experts in cancer and nutrition and cognitive interviews with 18 cancer survivors. The modified instrument (Nutrition Literacy Assessment Instrument for Breast Cancer, NLit-BCa) was pilot-tested with 17 high-risk women and 55 breast cancer survivors. We conducted the NLit-BCa on two separate occasions 4 weeks apart and assessed reliability by confirmatory factor analysis. Construct validity was evaluated by comparing results of the NLit-BCa to a Healthy Eating Index score derived from two separate 24-h dietary recalls. Content validity of the NLit-BCa was acceptable (0.93). Entire reliability for three instrument domains was substantial (>0.80), while remaining domains demonstrated fair or moderate reliability. Significant relationships were found between five of the six domains of nutrition literacy and diet quality (P < 0.05). The NLit-BCa is content valid and demonstrates promising reliability and construct validity related to diet quality, through a larger sample size, and removal of non-discriminating items is needed to confirm these findings. Thus, the NLit-BCa demonstrates potential for comprehensively measuring nutrition literacy in breast cancer populations.

    Background Approximately 600 million children of preschool and school age are anaemic worldwide. It is estimated that half of the cases are due to iron deficiency. Consequences of iron deficiency anaemia during childhood include growth retardation, reduced school achievement, impaired motor and cognitive development, and increased morbidity and mortality. The provision of daily iron supplements is a widely used strategy for improving iron status in children but its effectiveness has been limited due to its side effects, which can include nausea, constipation or staining of the teeth. As a consequence, intermittent iron supplementation (one, two or three times a week on nonconsecutive days) has been proposed as an effective and safer alternative to daily supplementation. Objectives To assess the effects of intermittent iron supplementation, alone or in combination with other vitamins and minerals, on nutritional and developmental outcomes in children from birth to 12 years of age compared with a placebo, no intervention or daily supplementation. Search methods We searched the following databases on 24 May 2011: CENTRAL (2011, Issue 2), MEDLINE (1948 to May week 2, 2011), EMBASE (1980 to 2011 Week 20), CINAHL (1937 to current), POPLINE (all available years) and WHO International Clinical Trials Registry Platform (ICTRP). On 29 June 2011 we searched all available years in the following databases: SCIELO, LILACS, IBECS and IMBIOMED. We also contacted relevant organisations (on 3 July 2011) to identify ongoing and unpublished studies. Selection criteria Randomised and quasi-randomised trials with either individual or cluster randomisation. Participants were children under the age of 12 years at the time of intervention with no specific health problems. The intervention assessed was intermittent iron supplementation compared with a placebo, no intervention or daily supplementation.

    Weight loss is common in elderly people with dementia, particularly those with Alzheimer' disease (AD), and feeding difficulties are major issues in their care in the later stages of the disease. In this study (REAL FR for Réseau sur la maladie d'Alzheimer Français) we prospectively used the Mini Nutritional Assessment (MNA) to examine the nutritional status of 479 subjects. Three groups of patients were studied: group 1 = 22 patients with undernutrition (MNA = 17), group 2 = 166 patients with risk of undernutrition (17 < MNA < 24), and group 3 = 291 patients without undernutrition (MNA = 24). Correlations with behavioral and psychological signs and symptoms of dementia (Neuropsychiatric Inventory NPI), with caregiver distress (Zarit), and with the Mini Mental State Examination (MMSE) were studied. Undernutrition is more frequently associated with low MMSE (p < 0.001), high behavioural disturbances (p < 0.001) and high distress of caregivers (p < 0.001). Risk of undernutrition is also associated with NPI (p < 0.001) and Zarit (p < 0.001). These first results in a French cohort of patients with AD underline the importance of the evaluation of nutritional status and finally the follow-up of eating behavior, cognitive status and the quality of life of the caregivers.

    Background: Leptin is secreted by adipose tissue and decreases appetite. However, the role of leptin in the pathogenesis of hemodialysis (HD)-related malnutrition has not been fully evaluated. Objectives: The aim of study was to investigate the association between the serum leptin levels, serum C-reactive protein (CRP) levels, and nutritional status in hemodialysis patients. Patients and Methods: This analytical descriptive study included 45 hemodialysis patients and 40 healthy subjects. Biochemical parameters and serum leptin levels were measured. The nutritional status was evaluated using a food frequency questionnaire (FFQ) and the calculation of the body mass index (BMI). Results: Serum leptin (P < 0.05) and albumin (P < 0.0001) levels and BMI (P < 0.001) of HD patients were significantly lower, while CRP levels were significantly higher than those of controls (P < 0.0001). HD patients consumed the lower daily servings of the food groups compared to the control subjects (P < 0.0001). A significant positive correlation between serum levels of leptin and albumin and BMI was demonstrated. No significant correlations were identified between leptin level, CRP level, and other variables. Conclusions: The findings suggest that low levels of leptin may be a contributory factor for malnutrition in HD patients. Further studies are required to ascertain the significance of leptin levels in relation to nutritional factors in hemodialysis patients. PMID:26430525

    The importance of early childhood development (ECD) is scientifically established and is increasingly recognized by governments and international organizations. However, progress in protecting and improving ECD is constrained by multisectoral influences on ECD, the multiple sectors and venues for delivering services, the lack of a common fiscal and policy space, and weak or fragmented data and monitoring systems. This paper describes two tools and strategies to strengthen multisectoral, system-wide policy environments for ECD. One is the Systems Approach for Better Education Results (SABER)-ECD framework for tracking progress toward an integrated ECD system. Developed by the World Bank, SABER-ECD assists governments and their partners to take stock of their existing ECD policies and programs, analyze strengths and areas for improvement using common metrics, and learn from international examples. The other tool is an Agenda-Setting and Commitments framework, based on research in global health and nutrition that can guide national-level actors in their advocacy and strategic efforts to strengthen the integrated ECD system. These represent practical and research-based tools to translate scientific evidence concerning ECD into effective and large-scale actions.

    The human gut contains a microbial community composed of tens of trillions of organisms that normally assemble during the first 2-3 y of postnatal life. We propose that brain development needs to be viewed in the context of the developmental biology of this "microbial organ" and its capacity to metabolize the various diets we consume. We hypothesize that the persistent cognitive abnormalities seen in children with undernutrition are related in part to their persistent gut microbiota immaturity and that specific regions of the brain that normally exhibit persistent juvenile (neotenous) patterns of gene expression, including those critically involved in various higher cognitive functions such as the brain's default mode network, may be particularly vulnerable to the effects of microbiota immaturity in undernourished children. Furthermore, we postulate that understanding the interrelationships between microbiota and brain metabolism in childhood undernutrition could provide insights about responses to injury seen in adults. We discuss approaches that can be used to test these hypotheses, their ramifications for optimizing nutritional recommendations that promote healthy brain development and function, and the potential societal implications of this area of investigation.

    Introduction Interventions to improve child diet are recommended as dietary patterns developed in childhood track into adulthood and influence the risk of chronic disease. For child health, childcare services are required to provide foods to children consistent with nutrition guidelines. Research suggests that foods and beverages provided by services to children are often inconsistent with nutrition guidelines. The primary aim of this study is to assess, relative to a usual care control group, the effectiveness of a multistrategy childcare-based intervention in improving compliance with nutrition guidelines in long day care services. Methods and analysis The study will employ a parallel group randomised controlled trial design. A sample of 58 long day care services that provide all meals (typically includes 1 main and 2 mid-meals) to children while they are in care, in the Hunter New England region of New South Wales, Australia, will be randomly allocated to a 6-month intervention to support implementation of nutrition guidelines or a usual care control group in a 1:1 ratio. The intervention was designed to overcome barriers to the implementation of nutrition guidelines assessed using the theoretical domains framework. Intervention strategies will include the provision of staff training and resources, audit and feedback, ongoing support and securing executive support. The primary outcome of the trial will be the change in the proportion of long day care services that have a 2-week menu compliant with childcare nutrition guidelines, measured by comprehensive menu assessments. As a secondary outcome, child dietary intake while in care will also be assessed. To assess the effectiveness of the intervention, the measures will be undertaken at baseline and ∼6 months postbaseline. Ethics and dissemination The study was approved by the Hunter New England Human Research Ethics Committee. Study findings will be disseminated widely through peer-reviewed publications. PMID

    The role of early nutrition as a cost-effective measure to ensure optimal infant growth, development, and long-term health is gaining attention. In particular, the role of supplementation with nutrients such as n-3 (omega-3) fatty acids, iron, zinc, and B vitamins, which are relevant to brain structure and function, is of interest. However, for all of these nutrients, there is a lack of clarity and no consensus regarding their role in the mental and motor development of children. Systematic reviews with or without a meta-analysis are a well-established means of reviewing existing evidence and of integrating findings from various studies, including those related to infant nutrition. In this article, I provide an overview of the basic principles of systematic review and meta-analysis of randomized controlled trials (RCTs) and summarize such evidence related to the effects of early nutrition on mental and motor development. The inclusion of only RCTs in a systematic review could be considered the major strength. Randomization is the only means to control for unknown and unmeasured differences between comparison groups as well as for those that are known and measured. However, even if only RCTs are included, reviews are not free of potential biases. An understanding of the strengths and limitations of the meta-analytic approach, which I discuss in this article, is needed by everyone involved in decision making regarding interventions assessed by this approach.

    Two hundred years ago, the United States was just emerging as a new nation. Chemistry and biology, on which the science of nutrition is based, were also just beginning or in their infancy. Dietetics and nutrition education, being applied sciences, were concerned then--as they are now--with the solution of practical problems of everyday living. Dietetics was an important part of medical practice in colonial days. Much of the teaching then about the value of diet in health and disease was provided by pithy statements, based on empiricism backed by authority, by which the science of medicine was taught to students, and by which health instruction was offered to the public. The experimental method of studying "Nature," promulgated by Francis Bacon, was just beginning to be employed in studies of nutrition. Delay in accepting experimental results, such as Lind's demonstration of the value of citrus fruits in the treatment of scurvy, may be attributed in part to a lack of understanding of the experimental method. In part, it may have been due to the absence of animal experimental methods that are capable of providing clear-cut and convincing evidence. Three of the greatest experimental scientists of the eighteenth century--Lavoisier, Count Rumford, and Benjamin Franklin--busied themselves with matters of concern to dietitians and home economists. Their work and that of others provided a firm foundation for the advances in scientific knowledge during the last two hundred years. PMID:1104697

    Background. Orang Asli (aborigine) children are susceptible to soil-transmitted helminth (STH) infections due to their lifestyle and substandard sanitation system. Objectives. This study aimed to examine the helminthic and nutritional status of Orang Asli school children in Sekolah Kebangsaan Pos Legap, a remote primary school at Kuala Kangsar District in the state of Perak, Malaysia. In addition, the sensitivities of four STH stool examination techniques were also compared. Methods. Demography and anthropometry data were collected by one-to-one interview session. Collected stools were examined with four microscopy techniques, namely, direct wet mount, formalin ether concentration (FEC), Kato-Katz (KK), and Parasep™. Results. Anthropometry analysis showed that 78% (26/33) of children in SK Pos Legap were malnourished and 33% (11/33) of them were stunted. Stool examinations revealed almost all children (97%) were infected by either one of the three commonest STHs. FEC was the most sensitive method in detection of the three helminth species. Conclusion. This study revealed that STH infections and nutritional status still remain a health concern among the Orang Asli children. These communal problems could be effectively controlled by regular monitoring of STH infection loads, administration of effective antihelminthic drug regimen, and also implementation of effective school nutritional programs.

    Recent evidence has shown that an unhealthy diet is associated with a higher risk of tumor recurrence, metastasis, and death among patients with colorectal cancer (CRC). The aims of this study were to assess nutritional adequacy and diet quality in a group of CRC patients postsurgery and to identify possible associations between dietary and nutritional aspects and environmental factors and weight status. This was an observational study conducted on a random sample of 74 patients, aged 50-69 years. Dietary intake was evaluated utilizing a validated frequency questionnaire, and diet quality was evaluated utilizing the Healthy Eating Index for Spanish Diet and the MedDietScore. Data regarding socioeconomic, demographic, lifestyles, dietary supplements use, and body mass index were collected. Subjects followed a diet characterized by a low carbohydrate intake (94% of the cases), excessive protein (48%), high fat intake (67%), and some micronutrient deficiencies. The inadequacy of some nutrients was associated with male gender, overweight/obesity, smoking, and low educational level; and low adherence to the MedDiet was identified in those with a low educational level (adjusted odds ratio = 4.16, P < 0.05). Therefore, such patients should be an important target group when applying educational programs and giving individualized nutritional advice to improve their quality of life. PMID:27144653

    Two hundred years ago, the United States was just emerging as a new nation. Chemistry and biology, on which the science of nutrition is based, were also just beginning or in their infancy. Dietetics and nutrition education, being applied sciences, were concerned then--as they are now--with the solution of practical problems of everyday living. Dietetics was an important part of medical practice in colonial days. Much of the teaching then about the value of diet in health and disease was provided by pithy statements, based on empiricism backed by authority, by which the science of medicine was taught to students, and by which health instruction was offered to the public. The experimental method of studying "Nature," promulgated by Francis Bacon, was just beginning to be employed in studies of nutrition. Delay in accepting experimental results, such as Lind's demonstration of the value of citrus fruits in the treatment of scurvy, may be attributed in part to a lack of understanding of the experimental method. In part, it may have been due to the absence of animal experimental methods that are capable of providing clear-cut and convincing evidence. Three of the greatest experimental scientists of the eighteenth century--Lavoisier, Count Rumford, and Benjamin Franklin--busied themselves with matters of concern to dietitians and home economists. Their work and that of others provided a firm foundation for the advances in scientific knowledge during the last two hundred years.

    Objective. This study aims to evaluate the effect of daily dietary nutritional supplement on somatic, psychological, and urogenital symptoms in postmenopausal women. Material and Methods. In this study 28 healthy, symptomatic, peri- and postmenopausal women of 47–67 years of age were allocated to use the nutritional supplement JuicePLUS+®. Primary research parameters: Menopause Rating Scale (MRS) was used to assess menopausal symptoms at baseline and after 8 and 16 weeks of treatment. Secondary parameters: proliferation behaviour of vaginal smear was scored at baseline and after treatment. Results. Treatment with the supplement resulted in a reduction of somatic, psychological, and urogenital symptoms. The overall MRS score showed an average improvement of 44.01%. Most benefits were observed for the psychological symptoms irritability (60.55%) and physical and mental exhaustion (49.08%); modest effects were observed for hot flashes (44.86%) and sleeping problems (35.56%). There was a minor improvement in sexual problems; 6 women reported an increased libido. No statistically significant effect was found in vaginal dryness and proliferation behaviour of vaginal mucosa. No adverse effects were observed. Conclusion. Dietary nutritional supplement may constitute an effective alternative therapy to conventional alternative medicine for somatic, psychological, and sexual symptoms.

    Background. Orang Asli (aborigine) children are susceptible to soil-transmitted helminth (STH) infections due to their lifestyle and substandard sanitation system. Objectives. This study aimed to examine the helminthic and nutritional status of Orang Asli school children in Sekolah Kebangsaan Pos Legap, a remote primary school at Kuala Kangsar District in the state of Perak, Malaysia. In addition, the sensitivities of four STH stool examination techniques were also compared. Methods. Demography and anthropometry data were collected by one-to-one interview session. Collected stools were examined with four microscopy techniques, namely, direct wet mount, formalin ether concentration (FEC), Kato-Katz (KK), and Parasep™. Results. Anthropometry analysis showed that 78% (26/33) of children in SK Pos Legap were malnourished and 33% (11/33) of them were stunted.

    Malnutrition has been associated with increased morbidity and mortality. The objective of this study was to determine the nutritional status and micronutrient levels of hospitalized patients in an infectious disease clinic and investigate their association with adverse clinical outcomes. The nutritional status of the study participants was assessed using the Nutritional Risk Screening 2002 (NRS 2002) and micronutrient levels and routine biochemical parameters were tested within the first 24 h of the patient’s admission. The incidence of zinc, selenium, thiamine, vitamin B6, vitamin B12 deficiency were 66.7% (n = 40), 46.6% (n = 29), 39.7% (n = 27), 35.3% (n = 24), 14.1% (n = 9), respectively. Selenium levels were significantly higher in patients with urinary tract infections, but lower in soft tissue infections. Copper levels were significantly higher in patients with soft tissue infections. In the Cox regression models, lower albumin, higher serum lactate dehydrogenase levels and higher NRS-2002 scores were associated with increased death. Thiamine, selenium, zinc and vitamin B6 deficiencies but not chromium deficiencies are common in infectious disease clinics. New associations were found between micronutrient levels and infection type and their adverse clinical outcomes. Hypoalbuminemia and a high NRS-2002 score had the greatest accuracy in predicting death, systemic inflammatory response syndrome and sepsis on admission. PMID:26938553

    The aim of this study was to estimate the prevalence and severity of feeding and nutritional problems in children with neurological impairment within a defined geographical area. In a cross-sectional study, a validated questionnaire was sent to 377 parents of children (aged 4 to 13 years) on the Oxford Register of Early Childhood Impairments with oromotor dysfunction. The return rate was 72%. Of these, 93% had cerebral palsy; 47% were unable to walk; 78% had speech difficulty; and 28% continuous drooling of saliva. Gastrointestinal problems were commonly encountered: 59% were constipated; 22% had significant problems with vomiting, and 31% had suffered at least one chest infection in the previous 6 months. Feeding problems were prevalent: 89% needed help with feeding and 56% choked with food; 20% of parents described feeding as stressful and unenjoyable. Prolonged feeding times (3h/day) were reported by 28%. Only 8% of participants received caloric supplements and 8% were fed via gastrostomy tube. Even though 38% of respondents considered their child to be underweight, 64% of children had never had their feeding and nutrition assessed. The results highlight that feeding problems in children with neurological impairment are common and severe, causing parental concern. Many of these children would benefit from nutritional assessment and management as part of their overall care.

    In developing recommendations for core measures/items for the evaluation of the Youth Expanded Food and Nutrition Education Program (EFNEP), three nutrition education curricula, implemented by land grant universities, were content analyzed. Selection criteria included the following: Curriculum content must include all EFNEP core content areas and must be implemented in more than one state with school children in third through fifth grades. Content analysis strategies were employed to identify and describe common areas/themes and mediators of behaviors addressed across the selected curricula. Content analysis coding was based on a list of behavioral mediators, which have empirical associations with nutrition, physical activity, and food safety. The most evident approaches identified across the three curricula were to enhance motivation, teach cognitive knowledge, and practice behavioral skills. The presence of self-regulation and environmental theory-based strategies was limited in all three curricula. In addition, multiple themes for nutrition, physical activity, and food safety were commonly addressed across curricula with multiple educational strategies. Based on these findings, recommendations for developing content appropriate measures and items for an outcome evaluation tool for Youth EFNEP are provided.

    Measuring the quality of the nutritional resources available to wild herbivores is critical to understanding trophic regulation processes. However, the direct assessment of dietary nutritional characteristics is usually difficult, which hampers monitoring nutritional constraints in natural populations. The feeding ecology of ruminant herbivores has been often assessed by analyzing fecal nitrogen (FN) concentrations, although this method has been less evaluated in other taxa. This study analyzed the suitability of FN as an indicator of ingesta quality in the European rabbit (Oryctolagus cuniculus), which is a keystone lagomorph species in Mediterranean ecosystems and of great conservation interest. Firstly, domestic O. cuniculus were used to evaluate under experimental conditions the accuracy of total FN and the metabolic FN as diet quality indicators of forages with characteristics similar to those available under natural conditions. Secondly, the accuracy of Near-Infrared Spectroscopy (NIRS) to calculate FN was tested using partial least squares regression. Thirdly, a pilot field study was conducted to monitor FN dynamics from wild O. cuniculus in three different habitats during wet and drought periods. A strong association was found between diet type and total FN and metabolic FN (Pseudo-R(2) ≥ 0.89). It was also found that NIRS calibrations were accurate for depicting nitrogen concentrations (R(2) > 0.98 between NIRS and chemical results). Finally, the seasonal FN dynamics measured in the field were consistent with current knowledge on vegetation dynamics and forage limitations in the three habitats. The results support the use of NIRS methods and FN indices as a reliable and affordable approach to monitoring the nutritional quality of rabbit habitats. Potential applications include the assessment of the mechanistic relationships between resource limitations and population abundance, e.g., in relation to natural drought cycles and to habitat interventions

    The present review describes brain imaging technologies that can be used to assess the effects of nutritional interventions in human subjects. Specifically, we summarise the biological relevance of their outcome measures, practical use and feasibility, and recommended use in short- and long-term nutritional studies. The brain imaging technologies described consist of MRI, including diffusion tensor imaging, magnetic resonance spectroscopy and functional MRI, as well as electroencephalography/magnetoencephalography, near-IR spectroscopy, positron emission tomography and single-photon emission computerised tomography. In nutritional interventions and across the lifespan, brain imaging can detect macro- and microstructural, functional, electrophysiological and metabolic changes linked to broader functional outcomes, such as cognition. Imaging markers can be considered as specific for one or several brain processes and as surrogate instrumental endpoints that may provide sensitive measures of short- and long-term effects. For the majority of imaging measures, little information is available regarding their correlation with functional endpoints in healthy subjects; therefore, imaging markers generally cannot replace clinical endpoints that reflect the overall capacity of the brain to behaviourally respond to specific situations and stimuli. The principal added value of brain imaging measures for human nutritional intervention studies is their ability to provide unique in vivo information on the working mechanism of an intervention in hypothesis-driven research. Selection of brain imaging techniques and target markers within a given technique should mainly depend on the hypothesis regarding the mechanism of action of the intervention, level (structural, metabolic or functional) and anticipated timescale of the intervention's effects, target population, availability and costs of the techniques.

    There is some evidence for paradoxical effects of nutritional labelling on energy intake particularly amongst restrained eaters and those with a higher body mass index (BMI) resulting in greater consumption of energy from foods with a positive health message (e.g. "low-fat") compared with the same foods, unlabelled. This study aimed to investigate, in a UK general population sample, the likelihood of paradoxical effects of nutritional labelling on energy intake. Participants (n = 287) attended a London cinema and were offered a large tub of salted or toffee popcorn. Participants were randomised to receive their selected flavour with one of three labels: a green low-fat label, a red high-fat label or no label. Participants watched two film clips while completing measures of demographic characteristics, emotional state and taste of the popcorn. Following the experiment, popcorn consumption was measured. There were no main effects of nutritional labelling on consumption. Contrary to predictions neither BMI nor weight concern moderated the effect of label on consumption. There was a three-way interaction between low-fat label, weight concern and socioeconomic status (SES) such that weight-concerned participants of higher SES who saw a low-fat label consumed more than weight unconcerned participants of similar SES (t = -2.7, P = .04). By contrast, weight-concerned participants of lower SES seeing either type of label, consumed less than those seeing no label (t = -2.04, P = .04). Nutritional labelling may have different effects in different socioeconomic groups. Further studies are required to understand fully the possible contribution of food labelling to health inequalities. PMID:24879885

    Background Improving nutritional care and support for people living with HIV (PLHIV) is an integral part of comprehensive HIV treatment according to the National Nutritional Strategy of Ethiopia. However, there is no adequate published study that assesses the nutritional care and support services for adult people living with HIV/ AIDS (PLHIV) in this setting. Objective The objective of the study was to identify the existing nutritional care and support services and determine the challenges facing adults living with HIV at Hawassa Referral Hospital in southern Ethiopia. Methods A qualitative study was carried out using focus group discussions (FGDs), in-depth interviews and participant observation. Four FDGs were held and five in-depth interviews were conducted. A two-week participant observation was also conducted by trained nurses. All interviews and FDGs were tape-recorded and transcribed; those conducted in Amharic were translated back to English. Finally thematic analysis of the transcripts was performed. Results Most of the FDG participants were unsatisfied with their nutritional care and support services and expressed difficulty with disclosing their HIV status for fear of stigma and discrimination. The in-depth interviews and participant observation showed results similar to those of the FDG. Some key informants expressed a fear that such poor nutritional care and support may threaten the quality of life of people living with HIV and suggested that all stakeholders work on improving the services. Conclusion Current nutritional care and support services for people living with HIV are not well coordinated. They focus mainly on monthly supplementation of antiretroviral drugs and occasional handouts of food. The need to provide health education on antiretroviral drugs and nutrition, and to emphasise strategies aimed at improving the nutritional status of peoples living with HIV is critical. Furthermore, the study recommended strengthening the initiatives of some

    Introduction Temporary ileostomy is an emergency procedure performed in cases having septic peritonitis in presence of perforation or obstruction or gangrene of small intestine. These patients usually suffer from gross malnutrition following surgery. Aim To measure nutritional status of patients with emergency temporary ileostomy and to determine whether their postoperative nutrition can be favourably maintained by oral diet alone. Materials and Methods Sixty patients were enrolled for the study on the basis of inclusion and exclusion criteria during the study period from January 2012 to December 2013. Oral feeding was started as soon as ileostomy started functioning and patients expressed hunger, about 48-72 hours postoperatively. An individualized diet chart was formulated for each patient using Harris Benedict Equation. Nutritional assessment was done on 1) 1st day of oral feeding, 2) After 7 days of oral feeding, 3). After three months of oral feeding. Nutritional parameters (anthropometric, biochemical) employed were tabulated and statistically analysed with SPSS v 17, Chicago. Results Out of 60 patients, 36 males and 24 females were enrolled in the study. The patients were in the age group of 20-60 years with a mean age of 45 years. After 7 days of oral nutrition the nutritional status deteriorated with a significant decrease in body weight (p<0.001) and serum haemoglobin (p <0.001). However, at the end of the study, the patients had their nutritional status restored satisfactorily with normalization of basic parameters like bodyweight, haemoglobin and serum albumin (p<0.001). Conclusion Proper dietary advice and oral nutrition were found to be sufficient for gradual restoration and maintenance of satisfactory nutritional status in the postoperative period. PMID:26816941

    The purpose of this review is to provide a summary of studies on the effectiveness nutrition education interventions used by college students. Electronic databases such as Medline, Science Direct, CINAHL (EBSCOhost), and Google Scholar were explored for articles that involved nutrition education interventions for college students and that were published between 1990 and 2011. Fourteen studies, which involved a total of 1668 college students as respondents, were identified and met the inclusion criteria. The results showed that there were 3 major forms of nutrition education interventions: web-based education, lectures, and supplement provisions. Dietary intake measures were used in almost all studies and were primarily collected with food records, recall, food frequency questionnaires, and dietary habit questionnaires. The outcome measures varied among the studies, with indicators such as consumption of food, nutrition knowledge, dietary habits, physical activity, and quality of life. Methodological issues were also identified. In general, college students experienced significant changes in their dietary habits after the interventions were employed. The highlighted methodological issues should be considered to improve the quality of similar research in future. PMID:22977369

    Athletes obtain nutritional information from their coaches, yet their competency in this area is lacking. Currently, no research exists in the UK which has a different coach education system to many other countries. Therefore, the aim of this study was to evaluate the sports nutrition knowledge of UK coaching certificate (UKCC) level 2 and 3, hockey and netball qualified coaches. All coaches (n = 163) completed a sports nutrition questionnaire to identify: (a) if they provided nutritional advice; (b) their level of sport nutrition knowledge; and (c) factors that may have contributed to their level of knowledge. Over half the coaches provided advice to their athletes (n = 93, 57.1%), even though they were not competent to do so. Coaches responded correctly to 60.3 ± 10.5% of all knowledge questions with no differences between those providing advice and those who did not (p > 0.05). Those coaches who had undertaken formal nutrition training achieved higher scores than those who had not (p < 0.05). In conclusion, UK sports coaches would benefit from continued professional development in sports nutrition to enhance their coaching practice.

  19. The Nutrition and Enjoyable Activity for Teen Girls (NEAT girls) randomized controlled trial for adolescent girls from disadvantaged secondary schools: rationale, study protocol, and baseline results

    2010-01-01

    Background Child and adolescent obesity predisposes individuals to an increased risk of morbidity and mortality from a range of lifestyle diseases. Although there is some evidence to suggest that rates of pediatric obesity have leveled off in recent years, this has not been the case among youth from low socioeconomic backgrounds. The purpose of this paper is to report the rationale, study design and baseline findings of a school-based obesity prevention program for low-active adolescent girls from disadvantaged secondary schools. Methods/Design The Nutrition and Enjoyable Activity for Teen Girls (NEAT Girls) intervention will be evaluated using a group randomized controlled trial. NEAT Girls is a 12-month multi-component school-based intervention developed in reference to Social Cognitive Theory and includes enhanced school sport sessions, interactive seminars, nutrition workshops, lunch-time physical activity (PA) sessions, PA and nutrition handbooks, parent newsletters, pedometers for self-monitoring and text messaging for social support. The following variables were assessed at baseline and will be completed again at 12- and 24-months: adiposity, objectively measured PA, muscular fitness, time spent in sedentary behaviors, dietary intake, PA and nutrition social-cognitive mediators, physical self-perception and global self-esteem. Statistical analyses will follow intention-to-treat principles and hypothesized mediators of PA and nutrition behavior change will be explored. Discussion NEAT Girls is an innovative intervention targeting low-active girls using evidence-based behavior change strategies and nutrition and PA messages and has the potential to prevent unhealthy weight gain and reduce the decline in physical activity and poor dietary habits associated with low socio-economic status. Few studies have reported the long-term effects of school-based obesity prevention programs and the current study has the potential to make an important contribution to the

This paper aims to evaluate data related to recruitment and retention across three research studies with young women, and present practical advice related to recruiting and retaining young women in order to optimise study quality within nutrition research. Methods Recruitment and retention strategies used in three nutrition studies that targeted young women (18 to 35 years) were critiqued. A randomised controlled trial (RCT), a crossover validation study and a cross-sectional survey were conducted at the University of Newcastle, Australia between 2010 and 2013Successful recruitment was defined as maximum recruitment relative to time. Retention was assessed as maximum participants remaining enrolled at study completion. Results Recruitment approaches included notice boards, web and social network sites (Facebook and Twitter), with social media most successful in recruitment. The online survey had the highest recruitment in the shortest time-frame (751 participants in one month). Email, phone and text message were used in study one (RCT) and study two (crossover validation) and assisted in low attrition rates, with 93% and 75.7% completing the RCT and crossover validation study respectively. Of those who did not complete the RCT, reported reasons were: being too busy; and having an unrelated illness. Conclusion Recruiting young women into nutrition research is challenging. Use of social media enhances recruitment, while Email, phone and text message contact improves retention within interventions. Further research comparing strategies to optimise recruitment and retention in young women, including flexible testing times, reminders and incentives is warranted. PMID:24433229

    2013-01-01

    Background This study used focus groups to pilot and evaluate a new nutrition label format and refine the label design. Physical activity equivalent labels present calorie information in terms of the amount of physical activity that would be required to expend the calories in a specified food item. Methods Three focus groups with a total of twenty participants discussed food choices and nutrition labeling. They provided information on comprehension, usability and acceptability of the label. A systematic coding process was used to apply descriptive codes to the data and to identify emerging themes and attitudes. Results Participants in all three groups were able to comprehend the label format. Discussion about label format focused on issues including gender of the depicted figure, physical fitness of the figure, preference for walking or running labels, and preference for information in miles or minutes. Feedback from earlier focus groups was used to refine the labels in an iterative process. Conclusions In contrast to calorie labels, participants shown physical activity labels asked and answered, “How does this label apply to me?” This shift toward personalized understanding may indicate that physical activity labels offer an advantage over currently available nutrition labels.

    The developing immune system and central nervous system in the fetus and child are extremely sensitive to both exogenous and endogenous signals. Early immune system programming, leading to changes that can persist over the life course, has been suggested, and other evidence suggests that immune dysregulation in the early developing brain may play a role in neurodevelopmental disorders such as autism spectrum disorder and schizophrenia. The timing of immune dysregulation with respect to gestational age and neurologic development of the fetus may shape the elicited response. This creates a possible sensitive window of programming or vulnerability. This review will explore the effects of maternal prenatal and infant nutritional status (from conception until early childhood) as well as maternal prenatal stress and anxiety on early programming of immune function, and how this might influence neurodevelopment. We will describe fetal immune system development and maternal-fetal immune interactions to provide a better context for understanding the influence of nutrition and stress on the immune system. Finally, we will discuss the implications for prevention of neurodevelopmental disorders, with a focus on nutrition. Although certain micronutrient supplements have shown to both reduce the risk of neurodevelopmental disorders and enhance fetal immune development, we do not know whether their impact on immune development contributes to the preventive effect on neurodevelopmental disorders. Future studies are needed to elucidate this relationship, which may contribute to a better understanding of preventative mechanisms. Integrating studies of neurodevelopmental disorders and prenatal exposures with the simultaneous evaluation of neural and immune systems will shed light on mechanisms that underlie individual vulnerability or resilience to neurodevelopmental disorders and ultimately contribute to the development of primary preventions and early interventions.

    Background There is substantial interest in the effects of nutrition labels on consumer food-purchasing behavior. However, conducting randomized controlled trials on the impact of nutrition labels in the real world presents a significant challenge. Objective The Food Label Trial (FLT) smartphone app was developed to enable conducting fully automated trials, delivering intervention remotely, and collecting individual-level data on food purchases for two nutrition-labeling randomized controlled trials (RCTs) in New Zealand and Australia. Methods Two versions of the smartphone app were developed: one for a 5-arm trial (Australian) and the other for a 3-arm trial (New Zealand). The RCT protocols guided requirements for app functionality, that is, obtaining informed consent, two-stage eligibility check, questionnaire administration, randomization, intervention delivery, and outcome assessment. Intervention delivery (nutrition labels) and outcome data collection (individual shopping data) used the smartphone camera technology, where a barcode scanner was used to identify a packaged food and link it with its corresponding match in a food composition database. Scanned products were either recorded in an electronic list (data collection mode) or allocated a nutrition label on screen if matched successfully with an existing product in the database (intervention delivery mode). All recorded data were transmitted to the RCT database hosted on a server. Results In total approximately 4000 users have downloaded the FLT app to date; 606 (Australia) and 1470 (New Zealand) users met the eligibility criteria and were randomized. Individual shopping data collected by participants currently comprise more than 96,000 (Australia) and 229,000 (New Zealand) packaged food and beverage products. Conclusions The FLT app is one of the first smartphone apps to enable conducting fully automated RCTs. Preliminary app usage statistics demonstrate large potential of such technology, both for

    Nutritional factors might play a role in regulating serum levels of insulin-like growth factors (IGFs), which are associated with some cancers. We examined the associations of nutritional factors with IGF-1 and IGF binding protein-3 (IGFBP-3). Serum IGF-1 and IGFBP-3 levels and dietary intake were measured in 459 black and 682 white male subjects of the Coronary Artery Risk Development in Young Adults study at the Year 7 (1992-1993) exam. Analysis of covariance and multivariable linear regression were used to assess associations of IGFs with dietary factors by race. IGF-1 was positively associated with magnesium in both black and white men (P = 0.008 and 0.05, respectively). Calcium was positively significantly related to IGF-1 in black men (P = 0.04) and marginally so in white men (P = 0.09). In black men, IGFBP-3 was positively associated with magnesium (P = 0.02), and one serving of milk per day was associated with an 8.23-ng/ml higher IGF-1 concentration (P = 0.05). Tests for interaction, however, revealed no differences between blacks and whites in the associations of nutrients with IGF-1 or IGFBP-3. In conclusion, the associations of dietary factors with serum IGF-1 and IGFBP-3 observed in our study corroborate those from other studies and generally do not differ between black and white men.

    Markets throughout the world have been reducing barriers to international trade and investment in recent years. The resulting increases in levels of international trade and investment have subsequently generated research interest into the potential population health impact. We present a systematic review of quantitative studies investigating the relationship between international trade, foreign direct investment and non-nutritional health outcomes. Articles were systematically collected from the SCOPUS, PubMed, EconLit and Web of Science databases. Due to the heterogeneous nature of the evidence considered, the 16 included articles were subdivided into individual level data analyses, selected country analyses and international panel analyses. Articles were then quality assessed using a tool developed as part of the project. Nine of the studies were assessed to be high quality, six as medium quality, and one as low quality. The evidence from the quantitative literature suggests that overall, there appears to be a beneficial association between international trade and population health. There was also evidence of the importance of foreign direct investment, yet a lack of research considering the direction of causality. Taken together, quantitative research into the relationship between trade and non-nutritional health indicates trade to be beneficial, yet this body of research is still in its infancy. Future quantitative studies based on this foundation will provide a stronger basis on which to inform relevant national and international institutions about the health consequences of trade policies.

    Certain food groups are often rejected during chemotherapy (CT) due to the side effects of treatment, which may interfere with adequate diet and nutritional status. The aim of this study was to evaluate the treatment impact on the diet and nutritional status of women with breast cancer (BC). In this prospective longitudinal study, conducted in 2014-2015, 55 women diagnosed with BC, with a mean age 51.5±10.1 years, were followed and data were collected at three different times. Anthropometric and dietary assessments were performed, the latter by applying nine 24h dietary recalls, by using the Brazilian Healthy Eating Index Revised (BHEI-R), and calculating the prevalence of inadequacy by the EAR cut-off point method. Regarding the BHEI-R analysis, the majority of women had a "diet requires modification', both at the beginning (T0, 58.2%, n = 32) and during treatment (T1, 54.5%, n = 30). However, after the end of the CT, the greater percentage of patients (T2, 49.1%, n = 27) were classified as having an "inadequate diet", since the Total Fruit consumption as well as the Dark Green and Orange Vegetable and Legume consumption decreased significantly during treatment (p = 0.043 and p = 0.026, respectively). There was a significant reduction in the intake of macro and micronutrients, with a high prevalence of inadequacy, of up to 100%, for calcium, iron, phosphorus, magnesium, niacin, riboflavin, thiamin, vitamin B6, vitamin C and zinc. Assessment of the nutritional status indicated that 56% (n = 31) of patients were overweight at these three different times. Weight, BMI and Waist Circumference increased significantly, indicating a worse nutritional status, and there was a correlation between poor diet quality and higher values for BMI, Waist-Hip Ratio and Waist-to-Height Ratio.

    One hundred ninety-two patients with previously untreated metastatic cancer (102 non-small-cell lung cancer [NSCLC]; 90 colorectal cancer) were randomized to receive either ad lib nutritional intake (control group) or specific nutritional intervention during a 12-week study period when chemotherapy was administered. Those patients randomized to nutritional interventions were counselled to take oral nutrients with caloric intake equal to 1.7 to 1.95 times their basal energy expenditure, depending on their pretreatment nutritional status ("standard" group). An augmented group was counselled to have a caloric intake equivalent to that of the standard group but with 25% of calories provided as protein and additional supplements of zinc and magnesium. Counselling increased caloric intake in both tumor types but reduced weight loss in the short term only for lung cancer patients. Ninety-three NSCLC patients were evaluable for tumor response to vindesine and cisplatin. Overall, only 20.4% of the patients responded, and there were no significant differences in response rates, median time to progression, or overall duration of survival between the nutrition intervention groups and the control group. The tumor response rate to time-sequenced 5-fluorouracil (5-FU) and methotrexate in the 81 evaluable patients with colorectal cancer was only 14.8%, and no significant differences in tumor response rates were noted between the three groups. Furthermore, the median time to progression and overall duration of survival were not different for the control, standard, and augmented groups. Nutritional interventions using dietary counselling had no impact on the percent of planned chemotherapy dose administered, the degree of toxicity experienced by patients, or the frequency of treatment delays. A multivariate prognostic factor analysis demonstrated that for lung cancer, the percent of weight loss, serum albumin concentration, and presence of liver metastases were significant (P less

    Many features of human susceptibility to chronic noncommunicable diseases can be mapped onto the framework of the match/mismatch hypothesis. From an evolutionary perspective, it is highly likely that the human genome has been under selective pressure to survive and reproduce against a background of seasonal food shortages and frequent episodic famines, leading to the attractive, but unproven, concept of 'a thrifty genotype made deleterious by famine'. From an ontogeny perspective, it has been clearly demonstrated that fetal undernutrition leads to a thrifty phenotype that enhances metabolic risk if the individual is later exposed to an energy-abundant environment. Data from developing and rapidly emerging countries permit insights into both of these pathways. Many populations are rapidly emerging from conditions broadly representative of human history over the past 600 or so generations (i.e. since the dawn of agriculture) and are transitioning within very few generations to a state of dietary abundance and low physical activity. And within this framework, many individuals make an even more rapid personal transition from the womb of a malnourished mother to a state of affluence. These journeys provide exceptional opportunities to interrogate thrifty genotype/phenotype theories, but such prospects are frequently impaired by a lack of robust data.

    The differential feeding regimes experienced by the queen and worker larvae of the honeybee Apis mellifera shape a complex endocrine response cascade that ultimately gives rise to differences in brain morphologies. Brain development analyzed at the morphological level from the third (L3) through fifth (L5) larval instars revealed an asynchrony between queens and workers. In the feeding phase of the last larval instar (L5F), two well-formed structures, pedunculi and calyces, are identifiable in the mushroom bodies of queens, both of which are not present in workers until a later phase (spinning phase, L5S). Genome-wide expression analyses and normalized transcript expression experiments monitoring specific genes revealed that this differential brain development starts earlier, during L3. Analyzing brains from L3 through L5S1 larvae, we identified 21 genes with caste-specific transcription patterns (e.g., APC-4, GlcAT-P, fax, kr-h1 and shot), which encode proteins that are potentially involved in the development of brain tissues through controlling the cell proliferation rate (APC4, kr-h1) and fasciculation (GlcAT-P, fax, and shot). Shot, whose expression is known to be required for axon extension and cell proliferation, was found to be transcribed at significantly higher levels in L4 queens compared with worker larvae. Moreover, the protein encoded by this gene was immunolocalized to the cytoplasm of cells near the antennal lobe neuropiles and proximal to the Kenyon cells in the brains of L4 queens. In conclusion, during the larval period, the brains of queens are larger and develop more rapidly than workers' brains, which represents a developmental heterochrony reflecting the effect of the differential feeding regime of the two castes on nervous system development. Furthermore, this differential development is characterized by caste-specific transcriptional profiles of a set of genes, thus pointing to a link between differential nutrition and differential

    The dietetics profession lacks a comprehensive definition of advanced-level practice. Using a three-round Delphi study with mailed surveys, expert consensus on four dimensions of advanced-level practice that define advanced practice registered dietitians (RDs) in clinical nutrition was explored. Purposive sampling identified 117 RDs who met advanced-level practice criteria. In round 1, experts rated the essentiality of statements on a 7-point ordinal scale and generated open-ended practice activity statements regarding the following four dimensions of advanced-level practice: professional knowledge, abilities and skills, approaches to practice, roles and relationships, and practice behaviors. Median ratings of 1.0 to 3.0 were defined as essential, 4.0 was neutral, and 5.0 to 7.0 were nonessential. In rounds 2 and 3, experts re-rated statements not reaching consensus by evaluating their previous responses, group median rating, and comments. Consensus was reached when the interquartile range of responses to a statement was ≤2.0. Eighty-five experts enrolled (72.6%); 76 (89.4%) completed all rounds. In total, 233 statements were rated, with 100% achieving consensus; 211 (90.6%) were essential to advanced practice RD clinical practice. Having a master's degree; completing an advanced practice residency; research coursework; and advanced continuing education were essential, as were having 8 years of experience; clinical nutrition knowledge/expertise; specialization; participation in research activities; and skills in technology and communication. Highly essential approaches to practice were systematic yet adaptable and used critical thinking and intuition and highly essential values encompassed professional growth and service to patients. Roles emphasized patient care and leadership. Essential practice activities within the nutrition care process included provision of complex patient-centered nutrition care using application of advanced knowledge/expertise and

    Although traditional risk factors for cardiovascular disease are common in dialysis patients, they alone cannot explain the unacceptably high prevalence of vascular disease in this patient group. Much recent interest has therefore focused on the role of various nontraditional cardiovascular risk factors, such as inflammation, wasting, obesity, vascular calcification, and oxidative stress. In addition, genetic factors such as single nucleotide polymorphisms (SNPs) may significantly influence the immune response, the levels of inflammatory markers and body composition, as well as the prevalence of vascular calcification in this patient group. While genetic variations in the tumor necrosis factor (TNF)-alpha-308 and interleukin (IL)-10 -1082 SNPs seem to be consistently associated with adverse clinical outcome in end-stage renal disease (ESRD) patients, the results regarding genetic variations in the IL-6 gene have been conflicting. To elucidate the respective role of DNA polymorphisms in the IL-6 and C-reactive protein (CRP) genes, as well as genes that encode vascular calcification inhibitors (such as fetuin-A, matrix Gla protein, and osteoprotegerin), sufficiently powered studies are needed in which both the protein product and the specific phenotype are determined. In addition, polymorphisms in genes related to body composition may be excellent candidates for analysis in the ESRD population, since nutritional parameters are strongly associated with adverse events in these patients. It seems conceivable that in the future, prognostic or predictive multigene DNA assays (which allow a simultaneous and rapid assessment of multiple genetic variants) will provide nephrologists with a more precise approach for the identification of "high-risk" ESRD patients and the development of accurate individualized treatment strategies.

    The Alberta Pregnancy Outcomes and Nutrition (APrON) study is an ongoing prospective cohort study that recruits pregnant women early in pregnancy and, as of 2012, is following up their infants to 3 years of age. It has currently enrolled approximately 5000 Canadians (2000 pregnant women, their offspring and many of their partners). The primary aims of the APrON study were to determine the relationships between maternal nutrient intake and status, before, during and after gestation, and (1) maternal mood; (2) birth and obstetric outcomes; and (3) infant neurodevelopment. We have collected comprehensive maternal nutrition, anthropometric, biological and mental health data at multiple points in the pregnancy and the post-partum period, as well as obstetrical, birth, health and neurodevelopmental outcomes of these pregnancies. The study continues to follow the infants through to 36 months of age. The current report describes the study design and methods, and findings of some pilot work. The APrON study is a significant resource with opportunities for collaboration.

    Two hundred registered dietitians in health care facilities in the United States were surveyed to ascertain practices in enteral nutrition formulary management. A random selection of members of the Clinical Nutrition Management Dietetic Practice Group of The American Dietetic Association comprised the sample population. The response rate was 74%. The facilities were typically private, nonprofit, acute-care, with a capacity of 201 to 500 beds. Dietetic departments were primarily responsible for procuring, preparing, and distributing enteral nutrition formulas, Physicians, however, primarily initiated orders for formulas. Approximately 15% of hospitalized patients required enteral nutrition formulas, yet modular formulas were rarely used. More than 75% of the facilities utilized enteral nutrition formularies. Ninety-five percent of dietitians believed that establishing objective criteria for evaluating enteral nutrition formulas was important. Cost-containment through decreased product duplication, staff education, inventory management, and quantity ordering advantages were cited as motivating factors in criteria development. Osmolarity, lactose content, and product availability were identified as being the most important criteria in enteral product evaluation. The costs of enteral formulas were included in the standard room rate when the dietetics department was responsible for procuring and supplying enteral formulas. Patients were billed directly when the pharmacy department was responsible for purchasing or supplying enteral products. This study provides data from which a model may be developed to guide health care professionals in enteral formulary decision making. PMID:2491869

    BACKGROUND/OBJECTIVES Dietary behavior and life stress in adolescence is related to growth rate and learning ability. This study was conducted to identify the relations between dietary habits, dietary attitude nutritional knowledge and life stress among high school girls in Korea and China. SUBJECTS/METHODS The subjects of this study were 221 high school girls in Korea and 227 high school girls in China. The questionnaire were about dietary habits, dietary attitude, nutritional knowledge and life stress. RESULTS The dietary habits of chinese girls were healthier than those of Korean girls with a significant difference (P < .001). There was no significant difference in dietary attitude between Korean girls and Chinese girls. Korean girls had more nutritional knowledge than Chinese girls with a significant difference (P < .001). Korean girls did less physical exercise but spent more time watching TV and using PCs, compared to Chinese girls. Korean girls' degree of confidence in nutrition information that they had learned and their performance in their real lives were low. Also, they had a low level of awareness of the need for nutritional education. There was no significant difference in life stress between the two groups. Dietary habits had a significantly negative correlation with life stress in both Korean and Chinese girls (P < .01, P < .001). As for Chinese students, dietary attitude had a negative correlation with life stress with a significant difference (P < .05). As for Korean girls, nutritional knowledge had a negative correlation with life stress with a significant difference (P < .05), which means as life stress was less, dietary habits were better. CONCLUSIONS This study shows that effective nutrition education programs should include components that encourage application of learned nutrition information to real life, increase physical exercise and reduce life stress.

    Background The Internet has become a widely used resource for information on cancer and for support. As part of the EuroCancerComs project (www.eurocancercoms.eu), an intervention study has been designed. The study aims to help patients with cancer providing an Internet “space” where to find information about nutritional care. Methods The study consists of a randomized 6-month intervention. The website (www.supportonutrizionale.it) hosts a contents area, prepared according to guidelines and recommendations, a forum and a blog. Subjects have been randomly allocated in intervention (IG) and control group (CG). IG has a free access to the website and it is involved in live activities, discussions and examinations. CG receives the same information by e-mail, without having access to the website. Three questionnaires are used to evaluate the effectiveness of the approach, concerning quality of life (QoL), psychological status and nutrition facts. Results Since the study startup, 191 subjects have been screened, and 58 (30%) have been randomized. Participants in both groups are mainly females, married and have at least a high school education level. Participants experienced a high psychological distress for 27% of IG and 33% of CG considering the four classes of scores at the baseline. Regarding QoL, a low “role functioning” score for IG and “emotional functioning” and “social functioning” scores for both groups are reported, while “fatigue” and “nausea and vomiting” respectively for IG and CG are the worsened symptoms compared with reference values. Considering the nutrition facts questionnaire, subjects showed a medium-high score profile and the worst scale regards “Nutrition and cancer knowledge”. From the beginning of the study, a total of 48 actions have been registered, including votes to contents, comments and forum messages. Conclusion The Internet has made possible the new forms of interaction and knowledge, and it is likely to become

    Background No studies on continuous renal replacement therapy (CRRT) have analyzed nutritional status in children. The objective of this study was to assess the association between mortality and nutritional status of children receiving CRRT. Methods Prospective observational study to analyze the nutritional status of children receiving CRRT and its association with mortality. The variables recorded were age, weight, sex, diagnosis, albumin, creatinine, urea, uric acid, severity of illness scores, CRRT-related complications, duration of admission to the pediatric intensive care unit, and mortality. Results The sample comprised 174 critically ill children on CRRT. The median weight of the patients was 10 kg, 35% were under percentile (P) 3, and 56% had a weight/P50 ratio of less than 0.85. Only two patients were above P95. The mean age for patients under P3 was significantly lower than that of the other patients (p = 0.03). The incidence of weight under P3 was greater in younger children (p = 0.007) and in cardiac patients and in those who had previous chronic renal insufficiency (p = 0.047). The mortality analysis did not include patients with pre-existing renal disease. Mortality was 38.9%. Mortality for patients with weight < P3 was greater than that of children with weight > P3 (51% vs 33%; p = 0.037). In the univariate and multivariate logistic regression analyses, the only factor associated with mortality was protein-energy wasting (malnutrition) (OR, 2.11; 95% CI, 1.067-4.173; p = 0.032). Conclusions The frequency of protein-energy wasting in children who require CRRT is high, and the frequency of obesity is low. Protein-energy wasting is more frequent in children with previous end-stage renal disease and heart disease. Underweight children present a
