    Malnutrition affects a large number of people throughout the developing world. Approaches to reducing malnutrition rarely focus on ecology and agriculture to simultaneously improve human nutrition and environmental sustainability. However, evidence suggests that interdisciplinary approaches that combine the knowledge bases of these disciplines can serve as a central strategy in alleviating hidden hunger for the world's poorest. To describe the role that ecological knowledge plays in alleviating hidden hunger, considering human nutrition as an overlooked ecosystem service. We review existing literature and propose a framework that expands on earlier work on econutrition. We provide novel evidence from case studies conducted by the authors in western Kenya and propose a framework for interdisciplinary collaboration to alleviate hidden hunger, increase agricultural productivity, and improve environmental sustainability. Our review supports the concept that an integrated approach will impact human nutrition. We provide evidence that increased functional agrobiodiversity can alleviate anemia, and interventions that contribute to environmental sustainability can have both direct and indirect effects on human health and nutritional well-being. Integrated and interdisciplinary approaches are critical to reaching development goals. Ecologists must begin to consider not only how their field can contribute to biodiversity conservation, but also, the relationship between biodiversity and provisioning of nontraditional ecosystem services such as human health. Likewise, nutritionists and agronomists must recognize that many of the solutions to increasing human wellbeing and health can best be achieved by focusing on a healthy environment and the conservation of ecosystem services.

    In contrast to the spectacular advances in the first half of the twentieth century with micronutrient-related diseases, human nutrition science has failed to stem the more recent rise of obesity and associated cardiometabolic disease (OACD). This failure has triggered debate on the problems and limitations of the field and what change is needed to address these. We briefly review the two broad historical phases of human nutrition science and then provide an overview of the main problems that have been implicated in the poor progress of the field with solving OACD. We next introduce the field of nutritional ecology and show how its ecological-evolutionary foundations can enrich human nutrition science by providing the theory to help address its limitations. We end by introducing a modeling approach from nutritional ecology, termed nutritional geometry, and demonstrate how it can help to implement ecological and evolutionary theory in human nutrition to provide new direction and to better understand and manage OACD.

    Throughout the life span, the brain is a metabolically highly active organ that uses a large proportion of total nutrient and energy intake. Furthermore, the development and repair of neural tissue depend on the proper intake of essential structural nutrients, minerals, and vitamins. Therefore, what we eat, or refrain from eating, may have an important impact on our cognitive ability and mental performance. Two of the key areas in which diet is thought to play an important role are in optimizing neurodevelopment in children and in preventing neurodegeneration and cognitive decline during aging. From early development to aging, brain imaging can detect structural, functional, and metabolic changes in humans and modifications due to altered nutrition or to additional nutritional supplementation. Inclusion of imaging measures in clinical studies can increase understanding with regard to the modification of brain structure, metabolism, and functional endpoints and may provide early sensitive measures of long-term effects. In this symposium, the utility of existing brain imaging technologies to assess the effects of nutritional intervention in humans is described. Examples of current research showing the utility of these markers are reviewed.

    The comet assay is a widely used biomonitoring tool for DNA damage. The most commonly used cells in human studies are lymphocytes. There is an urgent need to find an alternative target human cell that can be collected from normal subjects with minimal invasion. There are some reports of buccal cells, collected easily from the inside of the mouth, being used in studies of DNA damage and repair, and these were of interest. However, our preliminary studies following the published protocol showed that buccal cells sustained massive damage and disintegrated at the high pH [O. Ostling, K.J. Johanson. Microelectrophoretic study of radiation-induced DNA damages in individual mammalian cells. Biochem. Biophys. Res. Commun. 123 (1984) 291-298] used, but that at lower pH were extremely resistant to lysis, an essential step in the comet assay. Therefore, the aims of this study were to develop a protocol than enabled buccal cell lysis and DNA damage testing in the comet assay, and to use the model to evaluate the potential use of the buccal cell model in human biomonitoring and nutritional study. Specifically, we aimed to investigate intra- and inter-individual differences in buccal cell DNA damage (as strand breaks), the effect of in vitro exposure to both a standard oxidant challenge and antioxidant treatment, as well as in situ exposure to an antioxidant-rich beverage and supplementation-related effects using a carotenoid-rich food. Successful lysis was achieved using 0.25% trypsin for 30 min followed by proteinase K (1 mg/ml) treatment for 60 min. When this procedure was performed on cells pre-embedded in agarose on a microscope slide, followed by electrophoresis (in 0.01 M NaOH, 1 mM EDTA, pH 9.1, 18 min at 12 V), a satisfactory comet image was obtained, though inter-individual variation was quite wide. Pre-lysis exposure of cells to a standard oxidant challenge (induced by H{sub 2}O{sub 2}) increased DNA strand breaks in a dose related manner, and incubation of cells in

    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.

    1999-07-01

    This paper presents the speech delivered by Gro Harlem Brundtland, Director-General of WHO, on issues related to nutrition from a health and a human rights perspective. According to Brundtland, nutrition is a universal factor that both affects and defines the health of all people. It affects not only growth and physical development of a child, but also his cognitive and social development. However, inequity, poverty, underdevelopment, as well as inadequate access to food, health and care still exist which have resulted to the deaths of millions of children and left many more suffering from diseases. Poverty has also been identified as the main obstacle to the attainment of health. The existence of structural poverty and ill health eventually leads to poor development, which includes poor nutrition, poor health, and poor human rights. The impact of poverty on health is further worsened by discrimination on the basis of race, color, sex, language, or religion. To address this issue, the WHO will renew their focus on the political and legal links between health and human rights. A human rights perspective provides the international community with an opportunity to support the development of public health policies and practices that promote healthy nutrition as a center of all social and economic development.

  11. Isotope techniques in human studies of zinc nutrition. Report of an IAEA consultants' meeting

    1997-01-01

    A Consultants' Meeting was convened by the IAEA in November 1996 to review current knowledge of the role of zinc in human nutrition - with particular reference to (1) relevant public health issues in developing countries, and (2) the role that isotope techniques can play in increasing our understanding of some of these matters. More specifically, the Consultants Group was invited to advise the Agency on its future programmes in this area. It was concluded that there is now abundant scientific evidence that zinc deficiency of nutritional origin is a widespread phenomenon with important health consequences, particularly in developing countries. Even mild zinc deficiency is now thought to contribute to pregnancy complications, low birth weight, impaired immune competence, maternal and infant mortality and morbidity, and growth failure in infancy and childhood. Hence zinc deficiency may have far-reaching consequences for maternal, infant and child health in many developing countries. Isotope techniques - mainly using stable isotopes of zinc, but in some cases using radioisotopes - provide many possibilities 'for improving our understanding of the basic biochemical and metabolic functions of zinc, and for increasing our knowledge of the roles of this essential micronutrient in human nutrition. Through the use of isotope techniques, we may also expect to be better able to assess, and to increase, the efficacy of dietary and other intervention programmes designed to improve the nutritional status of developing country populations whose intakes are below the levels needed to achieve optimal health. This report briefly reviews some of these isotope techniques and makes recommendations on their use in IAEA research and technical co-operation programmes

    We describe a compact ultrafiltration system for the removal of pyrogens and bacteria from water labeled with the stable isotopes of deuterium and oxygen-18. The ultrafiltration system is constructed from readily available commercial components and can achieve complete removal of pyrogens and bacteria from 1L contaminated water within 30 min. By use of our procedure, loss of the isotopically labeled water by retention in the filtration system was minimal. The purified water is suitable for both oral and intravenous administration to healthy human subjects participating in nutrition studies

    Full Text Available 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.

    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.

    Foodchains are significant vectors of internal human radioactive contamination. Way of life, especially feeding habits are at present strikingly evolving under the influence of a better knowledge of food requirements and availability, greater use of additives, new technologies, economical, social and psychological factors. As a consequence, Cs and Pu in the diet vary, in spite of their unchanged concentration in the environment. Between source term and effective dose rate, many factors arise that lead to dose factor variability which must be quantified. These considerations should lead to a new optimization of radiological food control [fr

    Full text: The developing regions of the world are undergoing a rapid demographic and epidemiological transition. The number of child deaths and disease, and their causes, are important markers for this change and serve as indices of human development. More important to society at large is the change in the pattern of child growth of the survivors. Although they survive, a large proportion of children in developing countries fail to grow physically and develop mentally, thereby affecting not only health but also educational performance and economic productivity. National development is retarded at its root. In societies undergoing demographic transition, decreases in fertility rates usually lag behind changes in mortality by several decades. Thus, rapid population growth is typical of this transition. Dietary determinants of nutrition and health of populations undergoing transition also change. Typically, predominantly cereal-based food consumption patterns change to ones incorporating a greater proportion of animal food products, higher total fat and saturated fats, and a progressive inclusion of industrially processed food in the diet. The rural poor come to the cities and become the urban poor. They tend to live in precarious housing in unsanitary environments. Working merely for subsistence, they place great demands on governments to provide health and education services. The political dimension of these unsatisfied demands, in terms of unmet basic human needs, characterises life in developing societies. This situation not only fuels political struggles but is also the cause of great frustration to concerned scientists and health professionals. The impact of nutrition on infant survival and child growth is at the heart of what matters in the developing regions of the world. Most countries undergoing the nutrition transition have supplementary feeding programs and other major nutrition interventions targeted mainly at the urban and rural poor. For example, a

    This article reviews key findings about the long-term impact of a nutrition intervention carried out by the Institute of Nutrition of Central America and Panama from 1969 to 1977. Results from follow-up studies in 1988-89 and 2002-04 show substantial impact on adult human capital and economic productivity. The 1988-89 study showed that adult body size and work capacity increased for those provided improved nutrition through age 3 y, whereas the 2002-04 follow-up showed that schooling was increased for women and reading comprehension and intelligence increased in both men and women. Participants were 26-42 y of age at the time of the 2002-04 follow-up, facilitating the assessment of economic productivity. Wages of men increased by 46% in those provided with improved nutrition through age 2 y. Findings for cardiovascular disease risk factors were heterogeneous; however, they suggest that improved nutrition in early life is unlikely to increase cardiovascular disease risk later in life and may indeed lower risk. In conclusion, the substantial improvement in adult human capital and economic productivity resulting from the nutrition intervention provides a powerful argument for promoting improvements in nutrition in pregnant women and young children.

    Full Text Available In this paper, the significance of animal food (meat and milk in human nutrition and satisfaction of life needs with special look on health is reviewed. Meat is excelent source of proteins with high biological value.The proteins from meat are of high quality because they contain high share of essencial amino acids which are necessary for human organism. Polyunsaturated fatty acids, esspecialy those from ω3 group, became very importat to human nutritionists because they have significant role in prevention of stress induced deseases and of those induced by improper diets. New findings from western industrial countries point out the fact that longer intake of LA (ω-6 with relative “deficiency” of ω-3 is the main risk factor in occurence of cancer, coronary deseases (CHD, cerebrovascular deseases (CVD and alergic hyperactivity; not cholesterol as was considered till now. Therefore it is important to reduce the ω-6 / ω-3 acids ratio in meat and milk using some feedstufs in diets of animals. Dairy products contribute to health throughout life. Epidemiological researches as well as studies in animals and humans indicate that dairy food and/or their components have a protective effect against cancer. The potential anticancer agents identified so far in dairy foods include conjugated linoleic acid (CLA, calcium, vitamin D, sphingomyelin, butyric acid, ether lipids, protein and lactic acid bacteria. Milk is exclusive source of nutrients for the young and it also represents a high grade source of dietary nitrogen and indispensable amino acids for adults. Consumers are increasing looking for animal products, which could prevent disease or illness.Keywords: animal products, polyunsaturated fatty acids, meat, milk, nutrients.

Meat is excelent source of proteins with high biological value.The proteins from meat are of high quality because they contain high share of essencial amino acids which are necessary for human organism. Polyunsaturated fatty acids, esspecialy those from 3 group, became very importat to human nutritionists because they have significant role in prevention of stress induced deseases and of those induced by improper diets. New findings from western industrial countries point out the fact that longer intake of LA (-6 with relative “deficiency” of -3 is the main risk factor in occurence of cancer, coronary deseases (CHD, cerebrovascular deseases (CVD and alergic hyperactivity; not cholesterol as was considered till now. Therefore it is important to reduce the -6 / -3 acids ratio in meat and milk using some feedstufs in diets of animals. Dairy products contribute to health throughout life. Epidemiological researches as well as studies in animals and humans indicate that dairy food and/or their components have a protective effect against cancer. The potential anticancer agents identified so far in dairy foods include conjugated linoleic acid (CLA, calcium, vitamin D, sphingomyelin, butyric acid, ether lipids, protein and lactic acid bacteria. Milk is exclusive source of nutrients for the young and it also represents a high grade source of dietary nitrogen and indispensable amino acids for adults. Consumers are increasing looking for animal products, which could prevent disease or illness.

    Lukoyanova, O L; Borovik, T E

    The article provides an overview of the current literature on nutritional epigenetics. There are currently actively studied hypothesis that nutrition especially in early life or in critical periods of the development, may have a role in modulating gene expression, and, therefore, have later effects on health in adults. Nutritional epigenetics concerns knowledge about the possible effects of nutrients on gene expression. Human breast milk is well-known for its ability in preventing necrotizing enterocolitis, infectious diseases, and also non-communicable diseases, such as obesity and related disorders. This paper discusses about presumed epigenetic effects of human breast milk and some its components. While evidence suggests that a direct relationship may exist of some components of human breast milk with epigenetic changes, the mechanisms involved are stillunclear.

    Human development index (HDI) is extensively used to measure the standard of living of a country. India made a study progress in the HDI value. Extreme poverty is concentrated in rural areas of northern States while income growth has been dynamic in southern States and urban areas. This study was undertaken to assess the trends in HDI, human poverty index (HPI) and incidence of poverty among Indian states, the socio-economic, health, and diet and nutritional indicators which determine the HDI, changes in protein and calorie adequacy status of rural population, and also trends in malnutrition among children in India. The variations in socio-economic, demographic and dietary indicators by grades of HDI were studied. The trends in poverty and nutrition were also studied. Univariate, bivariate and multivariate analysis were done to analyse data. While India's HDI value has improved over a time; our rank did not improve much compared to other developing countries. Human poverty has not reduced considerably as per the HPI values. The undernutrition among preschool children is still a major public health problem in India. The incidence of poverty at different levels of calorie requirement has not reduced in both rural and urban areas. The time trends in nutritional status of pre-school children showed that, even though, there is an improvement in stunting over the years, the trend in wasting and underweight has not improved much. Proper nutrition and health awareness are important to tackle the health hazards of developmental transition. Despite several national nutrition programmes in operation, we could not make a significant dent in the area of health and nutrition. The changing dietary practices of the urban population, especially the middle class, are of concern. Further studies are needed to measure the human development and poverty situation of different sections of the population in India using an index, which includes both income indicators and non income

    Fortification of human milk is a standard practice for feeding very low birth weight infants. However, preterm infants often still experience suboptimal growth and feeding intolerance. New fortification strategies and different commercially available fortifiers have been developed. Commercially available fortifiers are constituted by a blend of ingredients from different sources, including plant oils and bovine milk proteins, thus presenting remarkable differences in the quality of macronutrients with respect to human milk. Based on the consideration that donkey milk has been suggested as a valid alternative for children allergic to cow's milk proteins, due to its biochemical similarity to human milk, we hypothesized that donkey milk could be a suitable ingredient for developing an innovative human milk fortifier. The aim of the study is to evaluate feeding tolerance, growth and clinical short and long-term outcomes in a population of preterm infants fed with a novel multi-component fortifier and a protein concentrate derived from donkey milk, in comparison to an analogous population fed with traditional fortifier and protein supplement containing bovine milk proteins. The study has been designed as a randomized, controlled, single-blind clinical trial. Infants born milk-based multicomponent fortifier and protein supplement, or a combination of a novel multicomponent fortifier and protein supplement derived from donkey milk. The fortification protocol followed is the same for the two groups, and the two diets were designed to be isoproteic and isocaloric. Weight, length and head circumference are measured; feeding tolerance is assessed by a standardized protocol. The occurrence of sepsis, necrotizing enterocolitis and adverse effects are monitored. This is the first clinical study investigating the use of a human milk fortifier derived from donkey milk for the nutrition of preterm infants. If donkey milk derived products will be shown to improve the feeding

    The general aim of our human nutrition project is to develop a health education model grounded in ‘everyday’ or ‘situated’ cognition (Hennessey, 1993). In 1993, we began pilot work to document adult understanding of human nutrition. We used a HyperCard stack as the basis for a series of interviews with 50 adults (25 university students, and 25 adults from offcampus). The interviews were transcribed and analysed using the NUDIST computer program. A summary of the views of these 50 adults on selected aspects of human nutrition is presented in this paper.

    Dairy and milk consumption are frequently included as important elements in a healthy and balanced diet. It is the first food for mammals and provides all the necessary energy and nutrients to ensure proper growth and development, being crucial in respect to bone mass formation. However, several controversies arise from consumption of dairy and milk products during adulthood, especially because it refers to milk from other species. Despite these controversies, epidemiologic studies confirm the nutritional importance of milk in the human diet and reinforce the possible role of its consumption in preventing several chronic conditions like cardiovascular diseases (CVDs), some forms of cancer, obesity, and diabetes. Lactose malabsorption symptoms and cow milk protein allergy are generally considered to be the adverse reactions to milk consumption. The present article reviews the main aspects of milk nutritional composition and establishes several associations between its nutritious role, health promotion, and disease prevention.

  8. The evolution of human phenotypic plasticity: age and nutritional status at maturity.

    Science.gov (United States)

    Gage, Timothy B

    2003-08-01

    Several evolutionary optimal models of human plasticity in age and nutritional status at reproductive maturation are proposed and their dynamics examined. These models differ from previously published models because fertility is not assumed to be a function of body size or nutritional status. Further, the models are based on explicitly human demographic patterns, that is, model human life-tables, model human fertility tables, and, a nutrient flow-based model of maternal nutritional status. Infant survival (instead of fertility as in previous models) is assumed to be a function of maternal nutritional status. Two basic models are examined. In the first the cost of reproduction is assumed to be a constant proportion of total nutrient flow. In the second the cost of reproduction is constant for each birth. The constant proportion model predicts a negative slope of age and nutritional status at maturation. The constant cost per birth model predicts a positive slope of age and nutritional status at maturation. Either model can account for the secular decline in menarche observed over the last several centuries in Europe. A search of the growth literature failed to find definitive empirical documentation of human phenotypic plasticity in age and nutritional status at maturation. Most research strategies confound genetics with phenotypic plasticity. The one study that reports secular trends suggests a marginally insignificant, but positive slope. This view tends to support the constant cost per birth model.

    2004-01-01

    The International Atomic Energy Agency (IAEA) is actively contributing through coordinated research project mechanisms to the development of isotopic techniques applicable for pollution-nutrition interactions. This CRP is based on the recommendations of a consultants' meeting on: 'Nuclear Analytical and Isotope Techniques for assessing nutrition-pollution interactions', NAHRES-62. The main objective of the CRP is to provide a scientific basis for better assessment of selected pollutants and nutrients in biological samples with a view to elucidate their interactions and the impact on human health. Results of this study will enhance the existing body of knowledge on nutrition-pollution interactions mechanisms and can be used to develop preventive strategies. SPECIFIC OBJECTIVES: Use of non-invasive specimens (e.g. breast milk, blood, hair, urine, placenta, eventually adipose tissue for organic pollutants) as indicators to monitor the interaction between the environmental pollution (both organic and inorganic) and nutritional status. Development of protocols to assess the health impact of environmental conditions on populations living under the risk of malnutrition.

    The Nutrition Risk Standing Review Panel (SRP) reviewed and discussed the specific gaps and tasks for the Human Health Countermeasures (HHC) Element related to nutrition identified in the Human Research Program (HRP) Integrated Research Plan. There was general consensus that the described gaps and proposed tasks were critical to future NASA mission success. The SRP acknowledged the high scientific quality of the work currently being undertaken by the Nutritional Biochemistry group under the direction of Dr. Scott Smith. In review of the entire HRP, four new gaps were identified that complement the Element's existing research activities. Given the limitations of ground-based analogs for many of the unique physiological and metabolic alterations in space, future studies are needed to quantify nutritional factors that change during actual space flight. In addition, future tasks should seek to better evaluate the time course of physiological and metabolic alterations during flight to better predict alterations during longer duration missions. Finally, given the recent data suggesting a potential role for increased inflammatory responses during space flight, the role of inflammation needs to be explored in detail, including the development of potential countermeasures and new ground based analogs, if this possibility is confirmed.

    1996-01-01

    Full Text Available Available evidence suggests that trace elements, such as zinc, once thought to have no nutritional relevance, are possibly deficient in large sections of the human population. Conditioned deficiencies have been reported to result from malabsorption syndromes, acrodermatitis enteropathica, alcoholism, gastrointestinal disease, thermal injury, chronic diseases (eg, diabetes, sickle cell anemia, and in total parenteral nutrition therapy. Awareness that patients with these problems are at risk has led health professionals to focus increasingly on the importance of zinc therapy in the prevention and treatment of deficiency. More recently zinc toxicity and its role in human nutrition and well-being have come under investigation. Reports have focused on the role of zinc toxicity in causes of copper deficiency, changes in the immune system and alterations in blood lipids. As the numerous challenges presented by the study of zinc in human nutrition are met, more appropriate recommendations for dietary and therapeutic zinc intake are being made.

    Proline plays important roles in protein synthesis and structure, metabolism (particularly the synthesis of arginine, polyamines, and glutamate via pyrroline-5-carboxylate), and nutrition, as well as wound healing, antioxidative reactions, and immune responses. On a pergram basis, proline plus hydroxyproline are most abundant in collagen and milk proteins, and requirements of proline for whole-body protein synthesis are the greatest among all amino acids. Therefore, physiological needs for proline are particularly high during the life cycle. While most mammals (including humans and pigs) can synthesize proline from arginine and glutamine/glutamate, rates of endogenous synthesis are inadequate for neonates, birds, and fish. Thus, work with young pigs (a widely used animal model for studying infant nutrition) has shown that supplementing 0.0, 0.35, 0.7, 1.05, 1.4, and 2.1% proline to a proline-free chemically defined diet containing 0.48% arginine and 2% glutamate dose dependently improved daily growth rate and feed efficiency while reducing concentrations of urea in plasma. Additionally, maximal growth performance of chickens depended on at least 0.8% proline in the diet. Likewise, dietary supplementation with 0.07, 0.14, and 0.28% hydroxyproline (a metabolite of proline) to a plant protein-based diet enhanced weight gains of salmon. Based on its regulatory roles in cellular biochemistry, proline can be considered as a functional amino acid for mammalian, avian, and aquatic species. Further research is warranted to develop effective strategies of dietary supplementation with proline or hydroxyproline to benefit health, growth, and development of animals and humans.

    Neutron Activation Analysis, NAA, has been successfully used on a regularly basis in several areas of nutrition and foodstuffs. NAA has become an important and useful research tool due to the methodology's advantages. These include high accuracy, small quantities of samples and no chemical treatment. This technique allows the determination of important elements directly related to human health. NAA also provides data concerning essential and toxic concentrations in foodstuffs and specific diets. In this paper some studies in the area of nutrition which have been carried out at the Neutron Activation Laboratory of IPEN/CNEN-SP will be presented: a Brazilian total diet study: nutritional element dietary intakes of Sao Paulo state population; a study of trace element in maternal milk and the determination of essential trace elements in some edible mushrooms.

    The International Atomic Energy Agency is a partner in addressing nutrition and health problems in more than 50 countries in collaboration with Member State counterparts, other United Nations organizations, and donors. In the general public, few people are aware that the work of the International Atomic Energy Agency extends beyond the realms of the nuclear power and safeguarding against the misuse of radioactive materials. Indeed, for many years now Agency activities in research and technical co-operation include a strong emphasis on isotope techniques as tools to evaluate human nutritional status and the nutritional quality of foods within the context of national development programmes. These techniques are considered the best methods for measuring the uptake and bioavailability of many important vitamins and minerals. Thus, they are well-suited for determining the success of food supplementation programmes and other interventions aimed at fighting many forms of malnutrition found throughout the world. (IAEA)

    2012-12-01

    While our caloric needs can mostly be met by wind-pollinated crops such as cereals, a recent analysis of USDA data shows that animal-pollinated crops contain the vast majority of many essential nutrients, including vitamins A and C, calcium, fluoride, and folic acid. In this work we combined global crop yield data with data on nutritional content in each crop to map nutrient production around the world, and to illustrate the value of pollination services to human nutrition. Spatially explicit crop yields (at 5 min resolution) were multiplied by crop nutrient content and by crop dependence on pollination to map where reductions in total nutrient production would occur if pollination services were removed. Nutrient demand maps (human nutrient requirements multiplied by population density) were generated to identify regions where local reduction in pollination services could threaten nutritional security. Nutrient deficiency maps (nutrient supply minus nutrient demand) were also created to identify hotspots where local crop production is not adequate to meet local nutritional needs.

    The present review examines the pig as a model for physiological studies in human subjects related to nutrient sensing, appetite regulation, gut barrier function, intestinal microbiota and nutritional neuroscience. The nutrient-sensing mechanisms regarding acids (sour), carbohydrates (sweet), glutamic acid (umami) and fatty acids are conserved between humans and pigs. In contrast, pigs show limited perception of high-intensity sweeteners and NaCl and sense a wider array of amino acids than humans. Differences on bitter taste may reflect the adaptation to ecosystems. In relation to appetite regulation, plasma concentrations of cholecystokinin and glucagon-like peptide-1 are similar in pigs and humans, while peptide YY in pigs is ten to twenty times higher and ghrelin two to five times lower than in humans. Pigs are an excellent model for human studies for vagal nerve function related to the hormonal regulation of food intake. Similarly, the study of gut barrier functions reveals conserved defence mechanisms between the two species particularly in functional permeability. However, human data are scant for some of the defence systems and nutritional programming. The pig model has been valuable for studying the changes in human microbiota following nutritional interventions. In particular, the use of human flora-associated pigs is a useful model for infants, but the long-term stability of the implanted human microbiota in pigs remains to be investigated. The similarity of the pig and human brain anatomy and development is paradigmatic. Brain explorations and therapies described in pig, when compared with available human data, highlight their value in nutritional neuroscience, particularly regarding functional neuroimaging techniques.

    Nutrition is paramount in shaping all aspects of animal biology. In addition, the influence of the intestinal microbiota on physiology is now widely recognized. Given that diet also shapes the intestinal microbiota, this raises the question of how the nutritional environment and microbial assemblages together influence animal physiology. This research field constitutes a new frontier in the field of organismal biology that needs to be addressed. Here we review recent studies using animal models and humans and propose an integrative framework within which to define the study of the diet-physiology-microbiota systems and ultimately link it to human health. Nutritional Geometry sits centrally in the proposed framework and offers means to define diet compositions that are optimal for individuals and populations. Copyright © 2017 Elsevier Inc.

    Ecosystems worldwide are being affected by numerous kinds of anthropogenic activities. Rapid and uncontrolled industrial growth in most part of the developing world has aggravated environmental contamination, some of which are potent pollutants. It is common knowledge that such pollutants significantly affect human health, as is the case with heavy metals and with organic dusts as an emerging concern. There is a distinction between pollution and contamination, in that a contaminant may be present in a given medium with or without causing harmful effects. Pollutants are regarded as agents causing harm to the environment subsequently leading to impairment of human health. Certain pollutants (e.g. lead absorption by anaemic subjects) cause ill health effects including deterioration of the nutritional status of individuals. Up until now, nutritional status and environmental pollution have mostly been treated as separate issues and there is very little information available about their relationship. Yet, previous studies have indicated that nutrition and pollution are interconnected with regard to their effects on human health. In recent years, a great deal of effort has been put into developing sensitive methods of measuring pollutants both in the environment and biological systems. However, the quantitative evaluation of impacts on health is still in its infancy and therefore far from satisfaction. To monitor the interaction between environmental pollution and nutrition, as well as health status, some indicators exist. Breast milk is an example of an indicator used for Real Time Monitoring (RTM). It has been demonstrated that the effect of the presence of pollutants in breast milk has an effect on morbidity and growth faltering in the nursing infant. Similarly, other non-invasive indicators such as urine and saliva and less invasive ones, as whole blood have commonly been used to monitor some pollutants (e.g. toxic metals). Placenta can also be employed as a dual

    This work was carried out to study the effect of adding drinking water with either, copper sulfate, ascorbic acid or drinking cooled water on growth performance (live body weight,body weight gain, feed intake, feed conversion and water consumption), digestibility coefficients of nutrients, carcass traits, some physiological parameters and economical efficiency of growing NZW rabbits under Egyptian summer conditions. Ninety six weanling New Zealand White (NZW) male rabbits at five weeks of age and nearly similar average body weight (650.3 ±3.7 g) were randomly divided into eight treatment groups (twelve rabbits in each group), and then each group was subdivided into four replicates, each of three rabbits. The rabbits were assigned to drinking water as follow: the 1 st group was given fresh tap water without any additives as a control. The 2 n d, 3 r d and 4 t h groups were given tap fresh water supplemented with copper sulfate at levels of 40, 80 and 120 mg/L drinking water, respectively. The 5 t h, 6 t h and 7 t h groups were given tap fresh water supplemented with ascorbic acid at levels of 250, 500 and 750 mg/L drinking water, respectively. The 8 t h group was given cooled drinking water (CW) at 10-15 degree C. Results showed that supplementation of 40 or 80 mg copper sulfate/L or 500 mg ascorbic acid/L to heat-stressed rabbits drinking water improved final live body weight, body weight gain, daily water consumption, feed conversion ratio, performance index and economical efficiency. Hot carcass percentage was significantly (P<0.01) decreased with 80 mg/L copper sulfate and increased significantly (P<0.01) due to supplementation the drinking water with 250 mg ascorbic acid/L. Cooled water (10-15 degree C) improved significantly (P<0.01) each of final body weight, body weight gain, feed conversion ratio, performance index, economical efficiency and decreased significantly (P<0.01) each of hot carcass %, dressed weight %, heart %, total giblets %, rectal

    Nutrition sensitive policy addresses the underlying determinants of nutrition-related disease and is a powerful tool in reducing the incidence of non-communicable disease. Some members of the food industry have long standing commitments to health-oriented nutrition policies. The aim of this study was to develop and apply a balanced scorecard of nutrition sensitive indicators to the policies of influential New Zealand food and beverage manufacturers and explore factors affecting policy processes. Results: The average nutrition sensitivity score of the twenty influential manufacturers policies was 42 against a benchmark of 75. Some manufacturers performed well whilst others had substantial scope for improvement, the largest variation was in policy development and implementation, whereas nutrition quality was relatively consistent. Manufacturers with written policy (n = 11) scored on average three times higher than their counterparts with verbal policy. The value a manufacturer placed on nutrition influenced whether formal nutrition policies were developed. The reputational risk of failing to deliver on publicly declared nutrition commitments acted as an informal accountability mechanism. We conclude the balanced scorecard offers a useful tool for assessing the nutrition sensitivity of influential food and beverage manufacturers’ policies. Our results provide a baseline for repeat assessments of the nutrition sensitivity of food manufacturers’ policies. PMID:29257049

    2013-01-01

    Analysis of stable carbon and nitrogen isotopes from soft or mineralized tissues is a direct and widely-used technique for modeling diets. In addition to its continued role in paleodiet analysis, stable isotope analysis is now contributing to studies of physiology, disease, and nutrition in archaeological and living human populations. In humans and other animals, dietary uptake and distribution of carbon and nitrogen among mineralized and soft tissue is carried out with varying efficiency due to factors of internal biology. Human pathophysiologies may lead to pathology-influenced isotopic fractionation that can be exploited to understand not just skeletal health and diet, but physiological health and nutrition. This study reviews examples from human biology, non-human animal ecology, biomedicine, and bioarchaeology demonstrating how stable isotope analyses are usefully applied to the study of physiological adaptation and adaptability. Suggestions are made for future directions in applying stable isotope analysis to the study of nutritional stress, disease, and growth and development in living and past human populations.

    In human nutrition research, nuclear analytical techniques, particularly neutron activation analysis (NAA), are used mainly for the in vitro study of trace elements. According to work sponsored by the IAEA, up to 15 trace elements and 5 minor elements of nutritional interest may be determined in biological materials by NAA with good accuracy and precision. A programme is described in which NAA was used for the determination of 14 trace elements and one minor element in human milk. NAA also plays an important role in the certification of reference materials for nutritional studies. (author) 17 refs.; 6 tables

    Milk is considered to be a complete food and an almost indispensable part of the diets of infants and children. In this paper we present the concentration of some radiologically and nutritionally important trace elements such as Th, Cs, Co, Rb, Fe, Ca and Zn present in human milk and commercially available milk. The trace elements in human and other milk samples were determined using instrumental neutron activation analysis technique. The results show that higher concentrations of Th, Cs, Ca and Rb were found in ordinary milk samples in comparison with the human milk samples. Whereas, a higher concentrations of Fe and Co were observed in human milk samples. These data will be useful for the nutritional and biokinetic studies of these elements in infants and children of different age groups. (author)

  15. Calcium in edible insects and its use in human nutrition

    Full Text Available Calcium is one of the most problematic substances in human nutrition. Nutrition in the present population is not optimal, because of insufficient consumption of milk and dairy products. Due to the expanding interest of specialists and the general public about entomophagy, as well as increase of the EU interest in this type of food, there is a need to consider the use of edible insects as an alternative source of nutrition. From the perspective of edible insects as a source of calcium, edible insects could be considered as a possible source of calcium for enriching the diet and also as a substitute for people with lactose intolerance and allergies to other categories of foods rich in calcium. Of the six analysed species of edible insect, Bombyx mori had the highest calcium content, almost comparable to semi-skimmed cow's milk. Gryllus assimillis can also be a rich source of calcium as well as other analysed species. The lowest content of calcium was detected in Zophobas morio. Common meat (chicken, beef, pork has lower calcium content comparing with all analysed species of edible insect (Apis mellifera, Bombyx mori, Gryllus assimillis, Locusta migratoria, Tenebrio molitor, Zophobas morio. Therefore, the selected species of edible insect could serve as an alternative source of calcium for people with lactose intolerance and allergies to soy. Phosphorus level in human body is closely related to calcium in the calcium-phosphate metabolism, therefore phosphorus level was detected in these samples too. Bombyx mori had the highest phosphorus content and the lowest content of phosphorus was measured in Zophobas morio samples.

    L-Tryptophan is the unique protein amino acid (AA) bearing an indole ring: its biotransformation in living organisms contributes either to keeping this chemical group in cells and tissues or to breaking it, by generating in both cases a variety of bioactive molecules. Investigations on the biology of Trp highlight the pleiotropic effects of its small derivatives on homeostasis processes. In addition to protein turn-over, in humans the pathways of Trp indole derivatives cover the synthesis of the neurotransmitter/hormone serotonin (5-HT), the pineal gland melatonin (MLT), and the trace amine tryptamine. The breakdown of the Trp indole ring defines instead the "kynurenine shunt" which produces cell-response adapters as L-kynurenine, kynurenic and quinolinic acids, or the coenzyme nicotinamide adenine dinucleotide (NAD(+)). This review aims therefore at tracing a "map" of the main molecular effectors in human tryptophan (Trp) research, starting from the chemistry of this AA, dealing then with its biosphere distribution and nutritional value for humans, also focusing on some proteins responsible for its tissue-dependent uptake and biotransformation. We will thus underscore the role of Trp biochemistry in the pathogenesis of human complex diseases/syndromes primarily involving the gut, neuroimmunoendocrine/stress responses, and the CNS, supporting the use of -Omics approaches in this field.

    Human milk feeding is encouraged for all infants; however, the mammary gland depends on maternal dietary intake of vitamins A, B1, B2, B6, B12, D, docosahexaenoic acid (DHA), choline, and iodine. Nutrition support team knowledge of maternal feeding guidelines for these nutrient sources can therefore impact infant intake. We hypothesized that these key nutrients for lactation in the mother's diet would be less than the dietary guidelines in the United States. This was a secondary analysis of nutrition data collected during a randomized, controlled trial. Dietary records were analyzed from 16 mothers (13 with singleton and 3 with multiple births) completing the study. Mean dietary intakes of selected nutrients were calculated and compared with the current dietary reference intakes. Mean maternal dietary intake for singletons was significantly (P vitamin A (58%), vitamin D (44%), and choline (58%);) DHA comprised only 5% of the current expert recommendation. Based on singleton recommendations, mothers to twins consumed an adequate intake except for DHA. Women providing breast milk for singleton preterm infants did not consume dietary reference intakes for key nutrients. Twin mothers' diets were adequate except for DHA, but these guidelines are based on singleton pregnancies and remain poorly understood for twin needs. The nutrition support team can have a unique role in maternal dietary education to impact human milk nutrient delivery to the infant. © 2018 American Society for Parenteral and Enteral Nutrition.

    Patients with end-stage cancer and advanced chronic bowel disease are often malnourished, which has a negative effect on patients' outcome, well-being, and activity. It is inconclusive whether these patients benefit from home parenteral nutrition. This prospective exploratory study investigates its influence on nutrition state, muscle strength, mobility, and quality of life. Patients ≥18 years old with an indication for home parenteral nutrition were included and followed for 2-24 months. Nutrition parameters, activity, and quality of life were assessed. Forty-eight patients participated (mean age 11.5 years), and 85% were severely malnourished (subjective global assessment score, class C). Four weeks after parenteral nutrition, patients with tumors demonstrated a deterioration in phase angle (from 3.9 to 3.4) and extracellular mass:body cell mass ratio (from 1.6 to 2.1), while patients with bowel disease improved (from 3.4 to 4.0 and 2.1 to 1.6, respectively); grip strength remained constant in both groups (difference: 1.11 and -2.11, respectively). Activity improved in patients with bowel disease but stayed the same in the tumor group (P = .02 and P = .33, respectively). When the groups were pooled, emotional and social functioning domain scores (P parenteral nutrition. Both groups seem to benefit from home parenteral nutrition without harmful side effects.

    In the context of the global obesity epidemic, national nutrition policies have come under scrutiny. The present paper examines whose interests - industry or public health - are served by these policies and why. Using an exemplary case study of submissions to an inquiry into obesity, the research compared the positions of industry and public health groups with that taken by government. We assessed whether the interests were given equal consideration (a pluralist model of influence) or whether the interests of one group were favoured over the other (a neo-pluralist model). 2006 New Zealand Inquiry into Obesity. Food and advertising industry and public health submitters. The Government's position was largely aligned with industry interests in three of four policy domains: the national obesity strategy; food industry policy; and advertising and marketing policies. The exception to this was nutrition policy in schools, where the Government's position was aligned with public health interests. These findings support the neo-pluralist model of interest group influence. The dominance of the food industry in national nutrition policy needs to be addressed. It is in the interests of the public, industry and the state that government regulates the food and advertising industries and limits the involvement of industry in policy making. Failure to do so will be costly for individuals, in terms of poor health and earlier death, costly to governments in terms of the associated health costs, and costly to both the government and industry due to losses in human productivity.

    To analyze if body mass index (BMI) and waist circumference (WC) as measures of nutritional status, and the Mini Nutritional Assessment Short Form (MNA-SF) as a nutritional risk measure are associated with increased risk of incident disability in basic activities of daily living (BADL) in a population based cohort of Spanish older adults. Concurrent cohort study. Albacete City, Spain. 678 subjects over age 70 from the FRADEA Study (Frailty and Dependence in Albacete). BMI, WC and MNA-SF were recorded at the basal visit of the FRADEA Study. Incident disability in BADL was defined as loss of the ability to perform bathing, grooming, dressing, toilet use, or feeding from basal to follow-up visit, using the Barthel index. The association between nutritional status and nutritional risk with incident BADL disability was determined by Kaplan-Meier analysis and logistic regression adjusted for age, sex, basal function, comorbidity, cognitive decline, depression risk and frailty status. Each point less of MNA-SF (OR 1.17, 95%CI 1.04-1.31) and MNA-SFanorexia almost reached the significance (OR 1.65, 95%CI 0.94-2.87). Nutritional risk measured with the MNA-SF is associated with incident disability in BADL in older adults, while nutritional status measured with BMI or WC is not.

    Full Text Available Background: There is a dearth of information on existing nutrition training programs in West Africa. A preliminary step in the process of developing a comprehensive framework to strengthen human capacity for nutrition is to conduct an inventory of existing training programs. Objective: This study was conducted to provide baseline data on university-level nutrition training programs that exist in the 16 countries in West Africa. It also aimed to identify existing gaps in nutrition training and propose solutions to address them. Design: Participating institutions were identified based on information provided by in-country key informants, UNICEF offices or through internet searches. Data were collected through semi-structured interviews during on-site visits or through self-administered questionnaires. Simple descriptive and bivariate analyses were performed. Results: In total, 83 nutrition degree programs comprising 32 B.Sc. programs, 34 M.Sc. programs, and 17 Ph.D. programs were identified in the region. More than half of these programs were in Nigeria. Six countries (Cape Verde, Guinea-Bissau, Liberia, Mali, The Gambia, and Togo offered no nutrition degree program.

    Full Text Available Breakfast is often referred to as the most important meal of the day and in recent years has been implicated in weight control, cardio-metabolic risk factors and cognitive performance although, at present, the literature remains inconclusive as to the precise health benefits of breakfast. There are extensive reports of breakfast’s contributions to daily food and nutrient intakes, as well as many studies that have compared daily food and nutrient intakes by breakfast consumers and skippers. However, significant variation exists in the definitions of breakfast and breakfast skippers, and in methods used to relate breakfast nutrient intakes to overall diet quality. The present review describes a novel and harmonised approach to the study of the nutritional impact of breakfast through The International Breakfast research Initiative involving national dietary survey data from Canada, Denmark, France, Spain, the UK and the USA. It is anticipated that the analysis of such data along harmonised lines, will allow the project to achieve its primary goal of exploring approaches to defining optimal breakfast food and nutrient intakes. Such data will be of value to public health nutrition policy-makers and food manufacturers and will also allow consistent messaging to help consumers to optimize food choices at breakfast.

    In case of shortage of breast milk despite proper lactation care or the poor state of the mother’s health, breast milk from human milk bank is recommended for feeding preterm infants This study retrospectively evaluated the first year of the operation of the Regional Human Milk Bank Data concerning donors was collected in the human milk bank during the cooperation. The clinical characteristics of the recipients was made on the basis of medical documentation from the Holy Family Hospital in Warsaw, Poland. Analysis of nutritional value was performed with the human milk analyzer (MIRIS AB) In the first year of activity, 45 voluntary donors established cooperation, donating from 650 to 32030 ml of human milk. The content of nutrients in milk provided by donors was variable - protein 0.4-1.5 g / 100 ml, fat 1.1-7.4 g / 100 ml, carbohydrates 6.3-7.9 g / 100 ml. The average length of using donated human milk was 4 days and the average volume of milk for one infant was 282 ml The donor profiles have a significant impact on the milk composition form HMB. The nutritional value can be improved by recruitment donors from mothers that gave birth prematurely and by beginning donation at earlier stages of lactation as soon as lactation is stabilized. In case of shortage of mothers own milk the immediate implementation of donors milk as a short-term support can significantly reduce the food intolerance incidence in the group of prematurely born infants

    We apply nutritional geometry, a framework for modelling the interactive effects of nutrients on animals, to help understand the role of modern environments in the obesity pandemic. Evidence suggests that humans regulate the intake of protein energy (PE) more strongly than non-protein energy (nPE), and consequently will over- and under-ingest nPE on diets with low or high PE, respectively. This pattern of macronutrient regulation has led to the protein leverage hypothesis, which proposes that the rise in obesity has been caused partly by a shift towards diets with reduced PE:nPE ratios relative to the set point for protein regulation. We discuss potential causes of this mismatch, including environmentally induced reductions in the protein density of the human diet and factors that might increase the regulatory set point for protein and hence exacerbate protein leverage. Economics--the high price of protein compared with fats and carbohydrates--is one factor that might contribute to the reduction of dietary protein concentrations. The possibility that rising atmospheric CO₂ levels could also play a role through reducing the PE:nPE ratios in plants and animals in the human food chain is discussed. Factors that reduce protein efficiency, for example by increasing the use of ingested amino acids in energy metabolism (hepatic gluconeogenesis), are highlighted as potential drivers of increased set points for protein regulation. We recommend that a similar approach is taken to understand the rise of obesity in other species, and identify some key gaps in the understanding of nutrient regulation in companion animals.

  12. Human health and nutrition: How isotopes are helping to overcome ''hidden hunger''

    1994-01-01

    In a number of ways, the work of the IAEA is contributing to efforts directed at overcoming hidden hunger and other nutrition problems. The rationale for the IAEA's involvement is twofold. First, adequate nutrition is an essential component of any strategy for improving health, and the IAEA's Statute specifically identifies ''enlarging the contribution of atomic energy to peace, health and prosperity'' as the major objective of programmes. Second, isotope techniques have a wide variety of applications -some of them unique - for targeted research in human nutrition, for assessing nutritional status, and for monitoring the effectiveness of nutritional intervention programmes. This article provides a brief overview of these techniques and their main applications in areas of human nutrition

    The increased number of articles published in nutrition is a reflection of the relevance to scientific community. The characteristics and quality of nutritional studies determine whether readers can obtain valid conclusions from them, as well as their usefulness for evidence-based strategic policies. To determine the characteristics of papers published in nutrition journals. Descriptive study design. We reviewed 330 original papers published between January-June 2007. From: American Journal of Clinical Nutrition (AJCN), Journal of Nutrition, European Journal Nutrition, European Journal of Clinical Nutrition and Public Health Nutrition. We classified them according to the subjects studied; risk factors, study design and country of origin. Almost half the papers studied healthy people (53.3%). The most frequent illness was obesity (13.9%). Food consumption is the most frequent risk factor (63.3%). Social factors appear exclusively only in 3.6% of the papers. Clinical trials were the most common analytical design (31.8%), mainly in the AJCN (45.6%). Cross-sectional studies were the most frequent type of observational design (37.9%). Ten countries produced over half of the papers (51.3%). The US publishes the highest number of papers (20.6%), whilst developing countries make only scarce contributions to scientific literature on nutrition. Most of the papers had inferential power. They generally studied both healthy and sick subjects, coinciding with the aims of international scientific policies. However, the topics covered reflect a clear bias, prioritizing problems pertaining to developed countries. Social determinants of health should also be considered, along with behavioral and biological risk factors.

    Lack of access to nutritious and balanced diets remains a major impediment to the health and well-being of people living in rural areas. The study utilizes a qualitative systematic approach to conduct an environmental scan and review of scientific literature of studies conducted in South Africa, specifically KwaZulu-Natal (KZN). Availability and access to nutritious, diverse and balanced diets were identified as key constraints for achieving food and nutrition security as well as for human health and well-being. This has led to both under- and over-nutrition, with the former, in particular stunting, affecting children under 5 years. A high incidence of over-nutrition, both overweight and obesity, was observed among black African females. In South Africa, poor people rely mostly on social grants and cannot afford a balanced diet. Under these circumstances, agriculture could be used to increase availability and access to diverse and nutritious foods for the attainment of a balanced diet. The wider use of traditional vegetable crops and pulses could improve availability and access to healthy and locally available alternatives. The promotion of household and community food gardens, and the use of nutrient dense crops with low levels of water use, i.e., high nutritional water productivity, offers prospects for addressing malnutrition in poor rural areas.

    Globally, the aging population is growing rapidly, creating an urgent need to attenuate age-related health conditions, including metabolic disease and disability. A promising strategy for healthy aging based on consistently positive results from studies with a variety of species, including non-human primates (NHP), is calorie restriction (CR), or the restriction of energy intake while maintaining intake of essential nutrients. The burgeoning evidence for this approach in humans is reviewed and the major study to date to address this question, CALERIE (Comprehensive Assessment of the Long-term Effects of Reducing Intake of Energy), is described. CALERIE findings indicate the feasibility of CR in non-obese humans, confirm observations in NHP, and are consistent with improvements in disease risk reduction and potential anti-aging effects. Finally, the mechanisms of CR in humans are reviewed which sums up the fact that evolutionarily conserved mechanisms mediate the anti-aging effects of CR. Overall, the prospect for further research in both NHP and humans is highly encouraging. Copyright © 2017 Elsevier B.V. All rights reserved.

    Plants are one of the most important resources of human foods and medicines. Rapidly increasing knowledge on nutrition, medicine, and plant biotechnology has dramatically changed the concepts about food, health and agriculture, and brought in a revolution on them. Nutritional therapy and phytotherapy have emerged as new concepts and healing systems have quickly and widely spread in recent years. Strong recommendations for consumption of nutraceuticals, natural plant foods, and the use of nutritional therapy and phytotherapy have become progressively popular to improve health, and to prevent and treat diseases. With these trends, improving the dietary nutritional values of fruits, vegetables and other crops or even bioactive components in folk herbals has become targets of the blooming plant biotechnology industry. This review attempts to display and remark on these aspects. It summarizes the progress made on nutraceuticals, nutritional therapy, phytonutrients, phytotherapy, and their related epidemiological investigations and clinical studies. It also covers markets of these health-promoting products and disease-preventing or healing systems, as well as regulations behind them that direct the development of biotechnology study and application. Finally, related patents are listed and briefly analyzed, regarding of plant biotechnological research and progress on transgenic crops to improve nutritional value, phytotherapy efficiency, or to produce pharmaceutically important secondary metabolites or high-valued protein medicines such as vaccines and antibodies.

  9. Pollination and Plant Resources Change the Nutritional Quality of Almonds for Human Health

    Insect-pollinated crops provide important nutrients for human health. Pollination, water and nutrients available to crops can influence yield, but it is not known if the nutritional value of the crop is also influenced. Almonds are an important source of critical nutrients for human health such as unsaturated fat and vitamin E. We manipulated the pollination of almond trees and the resources available to the trees, to investigate the impact on the nutritional composition of the crop. The pollination treatments were: (a) exclusion of pollinators to initiate self-pollination and (b) hand cross-pollination; the plant resource treatments were: (c) reduced water and (d) no fertilizer. In an orchard in northern California, trees were exposed to a single treatment or a combination of two (one pollination and one resource). Both the fat and vitamin E composition of the nuts were highly influenced by pollination. Lower proportions of oleic to linoleic acid, which are less desirable from both a health and commercial perspective, were produced by the self-pollinated trees. However, higher levels of vitamin E were found in the self-pollinated nuts. In some cases, combined changes in pollination and plant resources sharpened the pollination effects, even when plant resources were not influencing the nutrients as an individual treatment. This study highlights the importance of insects as providers of cross-pollination for fruit quality that can affect human health, and, for the first time, shows that other environmental factors can sharpen the effect of pollination. This contributes to an emerging field of research investigating the complexity of interactions of ecosystem services affecting the nutritional value and commercial quality of crops. PMID:24587215

  10. Stable isotopes in human nutrition research. Final report on an IAEA co-ordinated research programme, Vienna, Austria, 1993

    International Nuclear Information System (INIS)

    1993-01-01

    The Co-ordinated Research Programme (CRP) on Applications of Stable Isotope Tracers in Human Nutrition Research was established by the Agency in October 1988 and was completed in 1992. At various times during this period the CRP encompassed 16 participants in 16 countries. Its general objective was to help establish competence in the use of stable isotope techniques, particularly in developing countries, and particularly with reference to applications of 2 H, 13 C, 15 N, and 18 O in human nutrition research. Thereby it was hoped that it would be possible (i) to identify centres and scientists throughout the developing world who could use stable isotopes in human nutrition research, (ii) to assess the need for methodological adaptations for isotope-based methods in developing countries, and (iii) to advance the competence of the participants in using stable isotopes as tracers of human metabolism. In addition it was expected that the CRP would make a study of some major questions which have been identified by international groups of nutrition experts, particularly in areas relating to energy and protein metabolism. This document comprises copies of the working papers submitted by all CRP participants who contributed a final report on their project. These reports include details of the rationale, methods, results and interpretations from each of the respective studies. Refs, figs and tabs

    The calorie and nutritional requirements for a man working in an alien hostile environment of cold regions and high altitude are described and compared to those of normal requirements. Carbohydrates, fats and vitamins fulfilling the caloric and nutritional requirements are generally available in adequate amounts except under conditions of appetite loss. However, the proteins and amino acids should be provided in such a way as to meet the altered behavioral and metabolic requirements. Work in extreme cold requires fulfilling enhanced calorie needs. In high mountainous regions, cold combined with hypoxia produced loss of appetite and necessitated designing of special foods.

    In Senegal, the Laboratory of Nutrition of the Department of Animal Biology of the Faculty of Science and Technology of UCAD has been using stable isotopic techniques for nearly twenty years. Stable isotopes were applied to different target populations to measure milk production, exclusive breastfeeding, body composition, micronutrient bioavailability and total energy expenditure.The application of stable isotopic techniques in nutrition has contributed to advocacy for exclusive breastfeeding for up to 6 months in Senegal. It enabled government decision-makers to obtain essential information on the quality of foods needed for optimal effect during pregnancy and for infant growth and the results were reflected in the national policy on micronutrient supplementation.

There is almost no available information related to dietary practices among Omani athletes, especially during the competition. This study aimed to assess the nutritional practices (nutritional knowledge, eating habits and daily nutrients intake among Omani male handball athletes in Muscat city, Oman.Methods: This is a cross sectional study including 35 male handball athletes involved in serious training for no less than three years. Data collection was done through personal interviews using a study questionnaire which enlisted questions relating to socio-demographic information, anthropometric measurements and nutritional practices. All the study participants declared no intake of anabolic steroids.Results: The mean age of the study participants was 27 ± 3 years. Their anthropometric assessment revealed that their mean height was 166 ± 12 cm, mean weight was 75 ± 10 kg, and body mass index was 27 ± 3. Nutritional knowledge analysis revealed that 80% had no nutritional supervision by a nutritionist/dietitian. Their knowledge of nutritional requirements was only 23% correct for total energy intake, 63% for protein intake, 46% for carbohydrate intake, 11% for fat intake and 83% for water intake. Eating habits indicated that 55% had <3 meals/day, 51% had lunch as the principal meal, 51% always added extra salt to their food, 28% took protein supplements on a daily basis, and 51% used pre-competition glycogen load diet. However, none consumed vitamins or mineral supplements. The mean daily caloric intake was 3674 ± 265 kcal/day, which was roughly comprised of 596 ± 66 g carbohydrates, 147 ± 28 g of protein and 78 ± 20 g of total fat.Conclusion: Professional nutritional supervision is needed in order to improve the nutritional knowledge and eating habits of Omani athletes, and therefore improve their athletic performance.

    Empowerment is seen as a key strategy for sustainable health promotion efforts. However, there is only limited research on how to link the empowerment approach to the promotion of healthy eating, which is a major current public health issue. The article presents the development of a study framework for implementing and evaluating an empowerment intervention for healthy nutrition. This framework was created for a community intervention study meaning to involve elderly citizens in Bavaria, Germany. The study protocol was developed in an iterative process basing on (i) literature reviews on the topics empowerment in relation to healthy nutrition and mixed-methods evaluation, (ii) workshops with empowerment and public health experts and (iii) consultations with local community representatives. Through these measures we identified good practice criteria as well as specific challenges of integrating empowerment and healthy nutrition, e.g. engaging people in healthy nutrition, reconciling participants' nutrition preferences with public health nutrition priorities and evaluating bottom-up activities in the community. Consequences for the study design were deducted from the literature and the consultations, e.g. practical recommendations as to how power could be gradually assigned to group members. A qualitative mixed-method evaluation design was chosen to capture emergent empowerment processes. The study framework presented here is the first on empowerment and nutrition to provide explicit guidance on how empowerment may be applied to healthy nutrition and implemented and evaluated in the community context. © The Author 2015.

    The aim of this article is to review why the first 1000 days of life are a vulnerable period of human development and the long-term effects of a nutrition experiment carried out in Guatemala (1969-1977). In 1969-77, a supplement called Atole, containing high quality protein, energy and micronutrients, was provided to women during pregnancy and lactation and to children nutritional requirements, greater susceptibility to infections, high sensitivity to programming effects and full dependence on others for care, nutrition, and social interaction. Compared with Fresco, Atole improved total nutrient intakes (protein, energy, and micronutrients) and reduced stunting, but only in children nutrition intervention. This provides a powerful argument for promoting improvements in nutrition in pregnant women and young children in low income countries. © 2017 Wiley Periodicals, Inc.

    Full Text Available The present literature review is a part of the NNR5 project with the aim of reviewing and updating the scientific basis of the 4th edition of the Nordic Nutrition Recommendations (NNR issued in 2004. The main objective of the review is to assess the influence of different intakes of iodine at different life stages (infants, children, adolescents, adults, elderly, and during pregnancy and lactation in order to estimate the requirement for adequate growth, development, and maintenance of health. The literature search resulted in 1,504 abstracts. Out of those, 168 papers were identified as potentially relevant. Full paper selection resulted in 40 papers that were quality assessed (A, B, or C. The grade of evidence was classified as convincing, probable, suggestive, and no conclusion. We found suggestive evidence for improved maternal iodine status and thyroid function by iodine supplementation during pregnancy. Suggestive evidence was found for the relationship between improved thyroid function (used as an indicator of iodine status during pregnancy and cognitive function in the offspring up to 18 months of age. Moderately to severely iodine-deficient children will probably benefit from iodine supplementation or improved iodine status in order to improve their cognitive function, while only one study showed improved cognitive function following iodine supplementation in children from a mildly iodine-deficient area (no conclusion. No conclusions can be drawn related to other outcomes included in our review. There are no new data supporting changes in dietary reference values for children or adults. The rationale for increasing the dietary reference values for pregnant and lactating women in the NNR5 needs to be discussed in a broader perspective, taking iodine status of pregnant women in the Nordic countries into account.

    Oral administration of preformed specific antibodies is an attractive approach against infections of the digestive system in humans and animals in times of increasing antibiotic resistances. Previous studies showed a positive effect of egg yolk IgY antibodies on bacterial intoxications in animals and humans. Immunization of chickens with specific antigens offers the possibility to create various forms of antibodies. Research shows that orally applied IgY's isolated from egg yolks can passively cure or prevent diseases of the digestive system. The use of these alternative therapeutic drugs provides further advantages: (1) The production of IgY's is a non-invasive alternative to current methods; (2) The keeping of chickens is inexpensive; (3) The animals are easy to handle; (4) It avoids repetitive bleeding of laboratory animals; (5) It is also very cost effective regarding the high IgY concentration within the egg yolk. Novel targets of these antigen specific antibodies are Helicobacter pylori and also molecules involved in signaling pathways in gastric cancer. Furthermore, also dental caries causing bacteria like Streptococcus mutans or opportunistic Pseudomonas aeruginosa in cystic fibrosis patients are possible targets. Therefore, IgY's included in food for human consumption may be able to prevent or cure human diseases.

    1981-01-01

    A method based on Radiochemical Neutron Activation Analysis (RNAA) is described which allows simultaneous measurement of two stable isotopes of calcium, 46 Ca and 48 Ca, in human feces, plasma, and urine for the purpose of studying human nutrition and metabolism of calcium. It is shown that these measurements can be made with relative analytical precision of 1-5% depending on the particulars of a given experiment. The method has been applied in humans and data are given showing that kinetics of plasma appearance of 46 Ca administered orally with food can be readily investigated. This method allows investigation of a number of important nutritional and metabolic issues in all human population groups without regard to radioisotope safety considerations, and should prove especially helpful in relation to studies of calcium bioavailability from different foods in a variety of population groups for whom use of radiocalcium is not warranted.

    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.

    Nutrition has multiple roles during space flight from providing sufficient nutrients to meet the metabolic needs of the body and to maintain good health, to the beneficial psychosocial aspects related to the meals. Nutrition is central to the functioning of the body; poor nutrition compromises all the physiological systems. Nutrition is therefore likely to have a key role in counteracting the negative effects of space flight (e.g., radiation, immune deficits, oxidative stress, and bone and muscle loss). As missions increase in duration, any dietary/nutritional deficiencies will become progressively more detrimental. Moreover, it has been recognized that the human diet contains, in addition to essential macronutrients, a complex array of naturally occurring bioactive micronutrients that may confer significant long-term health benefits. It is therefore critical that astronauts be adequately nourished during missions. Problems of nutritional origin are often treatable by simply providing the appropriate nutrients and adequate recommendations. This review highlights six key issues that have been identified as space research priorities in nutrition field: in-flight energy balance; altered feeding behavior; development of metabolic stress; micronutrient deficiency; alteration of gut microflora; and altered fluid and electrolytes balance. For each of these topics, relevance for space exploration, knowledge gaps and proposed investigations are described. Finally, the nutritional questions related to bioastronautics research are very relevant to multiple ground-based-related health issues. The potential spin-offs are both interesting scientifically and potentially of great clinical importance.

    This study goes deeply through the nutrition of the first primate and analyses the nutrition in the line of human evolution. Simply dividing the shifts in the nutrition through the human evolution, it is obvious that some elements in the diet are more important than the others. Since the beginning of the Neolithic, the ratio of plant-to-animal foods in the diet has sharply increased from an average of probably 65% to 35% during Paleolithic times to as high as 90% to 10% since the advent of ag...

    The Mediterranean diet has been long associated with improved cardiovascular prognosis, chemoprevention, and lower incidence of neurodegeneration. Of the multiple components of this diet, olive oil stands out because its use has historically been limited to the Mediterranean basin. The health benefits of olive oil and some of its components are being rapidly decoded. In this paper we review the most recent pharma-nutritional investigations on olive oil biophenols and their health effects, chiefly focusing on recent findings that elucidate their molecular mechanisms of action.

    2017-01-01

    Food and nutrition insecurity continues to pose a serious global challenge, reflecting government shortcomings in meeting international obligations to ensure the availability, accessibility, and quality of food and to ensure the highest attainable standard of health of their peoples. With global drivers like climate change, urbanization, greater armed conflict, and the globalization of unhealthy diet, particularly in under-resourced countries, food insecurity is rapidly becoming an even greater challenge for those living in poverty. International human rights law can serve a critical role in guiding governments that are struggling to protect the health of their populations, particularly among the most susceptible groups, in responding to food and nutrition insecurity. This article explores and advocates for a human rights approach to food and nutrition security, specifically identifying legal mechanisms to "domesticate" relevant international human rights standards through national policy. Recognizing nutrition security as a determinant of public health, this article recognizes the important links between the four main elements of food security (i.e., availability, stability, utilization, and access) and the normative attributes of the right to health and the right to food (i.e., availability, accessibility, affordability, and quality). In drawing from the evolution of international human rights instruments, official documents issued by international human rights treaty bodies, as well as past scholarship at the intersection of the right to health and right to food, this article interprets and articulates the intersectional rights-based obligations of national governments in the face of food and nutrition insecurity.

    Zinc deficiency increases the risk and severity of a variety of infections, restricts physical growth, and affects specific outcomes of pregnancy. Global recognition of the importance of zinc nutrition in public health has expanded dramatically in recent years, and more experience has accumulated on the design and implementation of zinc intervention programs. Therefore, the Steering Committee of the International Zinc Nutrition Consultative Group (IZiNCG) completed a second IZiNCG technical document that reexamines the latest information on the intervention strategies that have been developed to enhance zinc nutrition and control zinc deficiency. In particular, the document reviews the current evidence regarding preventive zinc supplementation and the role of zinc as adjunctive therapy for selected infections, zinc fortification, and dietary diversification or modification strategies, including the promotion and protection of breastfeeding and biofortification. The purposes of this introductory paper are to summarize new guidelines on the assessment of population zinc status, as recommended by the World Health Organization (WHO), the United Nations Children's Fund (UNICEF), the International Atomic Energy Agency (IAEA), and IZiNCG, and to provide an overview on several new advances in zinc metabolism. The following papers will then review the intervention strategies individually.

    2015-01-01

    It is with great excitement we welcome you to the first edition of the NAHRES E-Newsletter. We intend to issue an E-Newsletter several times per year to share information about our latest projects, events, publications and more. Adequate nutrition is a fundamental cornerstone of development. The burden of malnutrition hinders the advancement of individuals, communities and countries and a concerted effort is needed to combat malnutrition in all its forms. The Nutritional and Health-Related Environmental Studies section of the IAEA complements the efforts of other UN agencies and NGO’s by supporting the use of nuclear techniques to understand changes in body composition following an intervention, and how the body is using the nutrients in the food we eat. This information helps nutrition policymakers decide what interventions will be most effective to reduce malnutrition. This mandate resonates with Article II of the IAEA's Statute: ''The Agency shall seek to accelerate and enlarge the contribution of atomic energy to peace, health and prosperity throughout the world.''Nuclear techniques add value by improving the specificity and sensitivity of nutritional evaluations such as the assessment of body composition, total daily energy expenditure, intake of human milk in breastfed infants, vitamin A status, and bioavailability of micronutrients from foods. The IAEA has promoted extensive use of these techniques in Member States through supporting national and regional nutrition projects via the Technical Cooperation Program and through Coordinated Research Projects addressing priority areas in nutrition.

    We studied links between human malnutrition and wild meat availability within the Rainforest Biotic Zone in central Africa. We distinguished two distinct hunted mammalian diversity distributions, one in the rainforest areas (Deep Rainforest Diversity, DRD) containing taxa of lower hunting sustainability, the other in the northern rainforest-savanna mosaic, with species of greater hunting potential (Marginal Rainforest Diversity, MRD). Wild meat availability, assessed by standing crop mammalian biomass, was greater in MRD than in DRD areas. Predicted bushmeat extraction was also higher in MRD areas. Despite this, stunting of children, a measure of human malnutrition, was greater in MRD areas. Structural equation modeling identified that, in MRD areas, mammal diversity fell away from urban areas, but proximity to these positively influenced higher stunting incidence. In DRD areas, remoteness and distance from dense human settlements and infrastructures explained lower stunting levels. Moreover, stunting was higher away from protected areas. Our results suggest that in MRD areas, forest wildlife rational use for better human nutrition is possible. By contrast, the relatively low human populations in DRD areas currently offer abundant opportunities for the continued protection of more vulnerable mammals and allow dietary needs of local populations to be met.

    2014-01-01

    Climate change and degradation of ecosystem services functioning may threaten the ability of current agricultural systems to keep up with demand for adequate and inexpensive food and for clean water, waste disposal and other broader ecosystem services. Human health is likely to be affected by changes occurring across multiple geographic and time scales. Impacts range from increasing transmissibility and the range of vector-borne diseases, such as malaria and yellow fever, to undermining nutrition through deleterious impacts on food production and concomitant increases in food prices. This paper uses case studies to describe methods that make use of satellite remote sensing and Demographic and Health Survey data to better understand individual-level human health and nutrition outcomes. By bringing these diverse datasets together, the connection between environmental change and human health outcomes can be described through new research and analysis.

    The Interagency Committee on Human Nutrition Research (ICHNR) is charged with improving the planning, coordination, and communication among federal agencies engaged in nutrition research and with facilitating the development and updating of plans for federal research programs to meet current and future domestic and international needs for nutrition. The ICHNR is co-chaired by the USDA Under Secretary for Research, Education, and Economics and Chief Scientist and the US Department of Health and Human Services Assistant Secretary for Health and is made up of >10 departments and agencies. Once the ICHNR was reassembled after a 10-y hiatus, the ICHNR recognized a need for a written roadmap to identify critical human nutrition research gaps and opportunities. This commentary provides an overview of the process the ICHNR undertook to develop a first-of-its-kind National Nutrition Research Roadmap, which was publicly released on 4 March 2016. The primary audience for the Roadmap is federal science agency leaders, along with relevant program and policy staff who rely on federally supported human nutrition research, in addition to the broader scientific community. The Roadmap is framed around the following 3 questions: 1 ) How can we better understand and define eating patterns to improve and sustain health? 2 ) What can be done to help people choose healthy eating patterns? 3 ) How can we develop and engage innovative methods and systems to accelerate discoveries in human nutrition? Within these 3 questions, 11 topical areas were identified on the basis of the following criteria: population impact, feasibility given current technological capacities, and emerging scientific opportunities. This commentary highlights initial federal and some professional research society efforts to address the Roadmap's research and resource priorities. We conclude by noting examples of early collaborations and partnerships to move human nutrition research forward in the 21st century. © 2017

Student of Human Nutrition and Dietetics, have reported shortcomings in their general competencies, such as organizational skills, teamwork, knowledge to develop proposals for intervention. Were given to students a problem-based learning (PBL activity with collaborative learning competence for to investigate their evolutions in collaborative learning and the knowledge in nutrition education. The results suggest that the PBL provided better preparation with respect to several of the competencies. The effect of PBL for the experienced students' collaborative learning and education nutrition competencies is especially promising in the professional development of future nutritionists.

    Banana inflorescences are popularly known as 'navels,' and they are used in Brazil as nutritional complements. However, the nutritional value of banana inflorescences (male flowers and bracts) has never been studied. Therefore, plant material of Musa acuminata, cultivar "ouro", was collected in Rio de Janeiro state, Brazil, and then submitted to chemical procedures to determine its nutritional composition. The experiment was arranged a completely randomized design and performed in triplicate. The sample composition analysis showed percentual average value for moisture, protein, fat and ash as 8.21, 14.50, 4.04 and 14.43, respectively. The dehydrated inflorescences were found to contain a significant nutritive complement based on their high content of potassium (5008.26 mg / 100 g) and fiber 49.83% (lignin, cellulose and hemicelluloses) revealing important functional and nutritional properties. In a parallel evaluation, the anatomical study revealed key elements for the recognition of Musa acuminata when reduced to fragments.

    Full Text Available Vitamin K occurs widely in foods and has been shown to have a beneficial effect on the cardiovascular system, as well as anticancer, anti-inflammatory, and antiosteoporosis properties. A previous study indicates that long-chain menaquinone-7 may be more bioavailable than vitamin K and short-chain menaquinones. In the present study, acute, subacute toxicity and genotoxicity assays were carried out to evaluate the safety of oral menaquinone-7 in albino Wistar rats. Oral administration of menaquinone-7, at a concentration of 2000 mg/kg, did not cause toxic symptoms in either male or female rats. A subacute toxicity study also proved the safety and tolerance of prolonged treatment (for 90 days with menaquinone-7 in rats, as evidenced by biochemical, hematological, and urine parameters as well as by histopathological analysis. Genotoxicity and mutagenicity studies were performed by comet, micronucleus, and Ames tests on Salmonella typhimurium strains, which showed cellular safety and nonmutagenicity of menaquinone-7. The results indicate the safety of menaquinone-7 for human consumption.

    Full Text Available The intrauterine environment is critical for fetal growth and organ development. Evidence from animal models indicates that the developing kidney is vulnerable to suboptimal maternal nutrition and changes in health status. However, evidence from human studies are yet to be synthesised. Therefore, the aim of the current study was to systematically review current research on the relationship between maternal nutrition during pregnancy and offspring kidney structure and function in humans. A search of five databases identified 9501 articles, of which three experimental and seven observational studies met the inclusion criteria. Nutrients reviewed to date included vitamin A (n = 3, folate and vitamin B12 (n = 2, iron (n = 1, vitamin D (n = 1, total energy (n = 2 and protein (n = 1. Seven studies were assessed as being of “positive” and three of “neutral” quality. A variety of populations were studied, with limited studies investigating maternal nutrition during pregnancy, while measurements of offspring kidney outcomes were diverse across studies. There was a lack of consistency in the timing of follow-up for offspring kidney structure and/or function assessments, thus limiting comparability between studies. Deficiencies in maternal folate, vitamin A, and total energy during pregnancy were associated with detrimental impacts on kidney structure and function, measured by kidney volume, proteinuria, eGFRcystC and mean creatinine clearance in the offspring. Additional experimental and longitudinal prospective studies are warranted to confirm this relationship, especially in Indigenous populations where the risk of renal disease is greater.

    2018-01-01

    The evaluation and treatment of older people's nutritional care is generally viewed as a low priority by nurses. However, given that eating and drinking are fundamental human activities, the support and enhancement of an optimal nutritional status should be regarded as a vital part of nursing. Registered nurses must therefore be viewed as having an important role in assessing and evaluating the nutritional needs of older people as well as the ability to intervene in cases of malnutrition. This study aimed to illuminate the experience of participating in nutritional care from the perspectives of older people and registered nurses. A further aim is to illuminate the latter's experience of nutritional care per se. A qualitative, descriptive design was adopted. Data were collected through semi-structured interviews ( n  = 12) with eight registered nurses and four older persons (mean age 85.7 years) in a city in the southern part of Sweden. The subsequent analysis was conducted by content analysis. The analysis reflected three themes: 'participation in nutritional care equals information', 'nutritional care out of remit and competence' and 'nutritional care more than just choosing a flavour'. They were interpreted to illuminate the experience of participation in nutritional care from the perspective of older people and RNs, and the latter's experience of nutritional care in particular per se. Our findings indicate that a paternalistic attitude in care as well as asymmetry in the nurse-patient relationship are still common characteristics of modern clinical nursing practice for older people. Considering that participation should be central to nursing care, and despite the RN's awareness of the importance of involving the older persons in their nutritional care this was not reflected in reality. Strategies to involve older persons in their nutritional care in a nursing home context need to take into account that for this population participation might not always be

    2013-01-01

    Entomophagy is widespread among nonhuman primates and is common among many human communities. However, the extent and patterns of entomophagy vary substantially both in humans and nonhuman primates. Here we synthesize the literature to examine why humans and other primates eat insects and what accounts for the variation in the extent to which they do so. Variation in the availability of insects is clearly important, but less understood is the role of nutrients in entomophagy. We apply a multidimensional analytical approach, the right-angled mixture triangle, to published data on the macronutrient compositions of insects to address this. Results showed that insects eaten by humans spanned a wide range of protein-to-fat ratios but were generally nutrient dense, whereas insects with high protein-to-fat ratios were eaten by nonhuman primates. Although suggestive, our survey exposes a need for additional, standardized, data.

    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

    To analyze the nutritional habits and attitudes of a semiprofessional soccer team. Nutritional study of 21 semiprofessional soccer players (18-35 years) by analyzing the daily energy intake and expenditure also the distribution of macro and micro-nutrients, differentiated type of day (normal, training or competition). The energy balance is negative in the three days studied (- 31%, - 38% and -31% respectively). There were significant differences in caloric intake between the day of competition, a normal day and a day of training. These differences are observed both in absolute values (2,438 kcal vs 2,127 y 2,221 kcal respectively) as referring to body weight (30.5 kcal/kg vs 27 y 28 kcal/kg respectively). Regarding macronutrient intake, the samples eat a diet with an insufficient amount of carbohydrates (328 g vs 371 and 540 g recommended in function of physical activity). There were no significant differences in the composition of micronutrients. The football players studied show a negative energy balance with a diet low in carbohydrates. This poor nutritional status may interfere with the development of their sporting performance and, ultimately, increase the risk of lesions. This implies the need for design and implementation of a diet and introducing nutritional education programs for these athletes. Copyright © AULA MEDICA EDICIONES 2013. Published by AULA MEDICA.

    There is currently an abundance of quantitative information regarding foods we consume, such as their total nutrient composition and daily nutritional requirements. In this study, we systematically analyzed such large-scale data of foods to better understand how the composition of foods affects their overall nutritional value. Herein, we constructed two types of networks that reflect nutritional data from about 700 food products: 1) The Food-food Network, in which each edge connects a pair of foods having similar nutritional contents; and 2) the Nutrient-nutrient Network, which is based on co-occurrence patterns of different nutrients across foods. By adopting the insight we obtained from the topological properties of these networks, we present a novel measure to quantify the overall nutritional value of a food, which we call the Nutritional Fitness (NF). Some nutrients can hinder foods from having high NF, acting as ``nutritional bottlenecks.'' Interestingly, a food's NF is not only affected by individual nutrients, but also pairs of nutrients. To this effect, foods with very high NFs tend to have unique nutrient pairs not observed from the majority of foods. To summarize, our study provides insight into how NF and nutrients are intricately related.

    Researchers are increasingly interested in using human biomonitoring - the measurement of chemicals, their metabolites or specific reaction products in biological specimens/body fluids - for investigating exposure to environmental chemicals. General population human biomonitoring programs are useful for investigating human exposure to environmental chemicals and an important tool for integrating environment and health. One of these programs, the National Health and Nutrition Examination Survey (NHANES), conducted in the United States is designed to collect data on the health and nutritional status of the noninstitutionalized, civilian U.S. population. NHANES includes a physical examination, collecting a detailed medical history, and collecting biological specimens (i.e., blood and urine). These biological specimens can be used to assess exposure to environmental chemicals. NHANES human biomonitoring data can be used to establish reference ranges for selected chemicals, provide exposure data for risk assessment, and monitor exposure trends. Published by Elsevier GmbH.

    One of the most important peaceful applications of isotopes is in research for the enhancement of our understanding for increased crop production and better management of resources with higher economic efficiency and environmental safety. Nuclear techniques helped in generating useful information on such aspects as use-efficiency of fertilizer nutrients, quantifying their losses from soil and their biological transformations. Such information was, hitherto, obtained indirectly by conventional methods. Radio and stable isotopes have also been successfully employed for getting information in such diverse fields as soil erosion, turnover of soil organic matter, pesticide retention in soil ground water recharge etc. The property of 137 Cs adhering tightly to certain exchange surface in soil and its chemically inert nature has made it a useful tool for soil erosion studies. In this paper, applications of isotopes in the research and other such studies as degradation, movement and retention of pesticides, movement of nitrate in soil, biological and ammoniacal nitrogen fixation in soil is discussed

  3. Nutrition and muscle loss in humans during spaceflight

    Science.gov (United States)

    Stein, T. P.

    1999-01-01

    The protein loss in humans during spaceflight is partly due to a normal adaptive response to a decreased work load on the muscles involved in weight bearing. The process is mediated by changes in prostaglandin release, secondary to the decrease in tension on the affected muscles. On missions, where there is a high level of physical demands on the astronauts, there tends to be an energy deficit, which adds to the muscle protein loss and depletes the body fat reserves. While the adaptive response is a normal part of homeostasis, the additional protein loss from an energy deficit can, in the long run, have a negative effect on health and capability of humans to live and work in space and afterward return to Earth.

    Full Text Available Little research has explored how nutrition content in midwifery education prepares midwives to provide prenatal nutrition advice. This study examined the nature and extent of nutrition education provided in Australian midwifery programmes. A mixed-methods approach was used, incorporating an online survey and telephone interviews. The survey analysis included 23 course coordinators representing 24 of 50 accredited midwifery programmes in 2012. Overall, the coordinators considered nutrition in midwifery curricula and the midwife’s role as important. All programmes included nutrition content; however, eleven had only 5 to <10 hours allocated to nutrition, while two had a designated unit. Various topics were covered. Dietitians/other nutrition experts were rarely involved in teaching or reviewing the nutrition content. Interviews with seven coordinators revealed that nutrition education tended to be problem-oriented and at times based on various assumptions. Nutrition content was not informed by professional or theoretical models. The development of nutrition assessment skills or practical training for midwifery students in providing nutrition advice was lacking. As nutrition is essential for maternal and foetal health, nutrition education in midwifery programmes needs to be reviewed and minimum requirements should be included to improve midwives’ effectiveness in this area. This may require collaboration between nutrition experts and midwifery bodies.

    Full Text Available The Department of Basic Education (DBE has not given nutrition education the necessary emphasis that it needs, despite its importance in South African schools. Nutrition is included as only one of many topics forming part of the Life Orientation syllabus. Educators are role models for learners in making healthy food choices, however, studies have shown that major gaps exist in the health and nutrition-related knowledge and behaviour of educators.The objective of this research was to undertake a pilot study to determine the impact of a nutrition education programme (NEP on the nutrition knowledge of Life Orientation educators in public schools in South Africa (SA. An exploratory baseline survey, to determine the nutrition education practices in 45 purposively selected public schools, was carried out before the experimental nutrition education intervention study. A nutrition knowledge questionnaire was completed by 24 purposively selected educators, representing all nine provinces in SA, before and after a three-day NEP. Pre and post-NEP data were analysed on the Statistical Package for Social Sciences (SPSS for a Windows program version 17.0 for descriptive statistics, version 17.0. Paired t-tests measured statistically significant differences (p < 0.05 before and after the NEP.The knowledge of the respondents improved significantly after the NEP as the mean±s.d. score of correctly answered questions (n = 59 improved from 63.3±30.2% before to 80.6±21.1% after the NEP. The results proved that nutrition knowledge of Life Orientation educators in primary schools is not optimal, but can be improved by NEP.

  7. Interactions with human nutrition and other indices of population health

    The contamination of food is an important pathway involved in the internal combination of humans. The site-related critical foodstuffs can be grouped into three main categories: dairy products; aquatic animals, such as fish, molluscs and crustaceans; and other typical foods. The concentration factor plays a more important role than the amount of a certain food consumed. Semi-natural and natural ecosystems are of special interest in this content because they can provide critical pathways for radionuclide transfer to humans, and they can also act as temporary sinks or long-term sources for radionuclides deposited from the atmosphere. From the viewpoint of population health, another important role is played by the countermeasures. The reference values commonly adopted in radiation protection are conservative and they have been established for planning practices that could provide future sources of irradiation. After a large release of radionuclides, the evaluation of the problem must be as realistic as possible, otherwise the countermeasures will imply consequences worse than those produced by the accident itself (without any further intervention). This criterion was clearly stated by the International Commission on Radiological Protection but it was frequently neglected after the Chernobyl accident. The results of a survey on the number of induced abortions following this incident are reported. These suggest that moral and ethical problems are involved above and beyond any economical implications. (Author)

    High-yielding cereals and other staples have produced adequate calories to ward off starvation for much of the world over several decades. However, deficiencies in certain amino acids, minerals, vitamins and fatty acids in staple crops, and animal diets derived from them, have aggravated the problem of malnutrition and the increasing incidence of certain chronic diseases in nominally well-nourished people (the so-called diseases of civilization). Enhanced global nutrition has great potential to reduce acute and chronic disease, the need for health care, the cost of health care, and to increase educational attainment, economic productivity and the quality of life. However, nutrition is currently not an important driver of most plant breeding efforts, and there are only a few well-known efforts to breed crops that are adapted to the needs of optimal human nutrition. Technological tools are available to greatly enhance the nutritional value of our staple crops. However, enhanced nutrition in major crops might only be achieved if nutritional traits are introduced in tandem with important agronomic yield drivers, such as resistance to emerging pests or diseases, to drought and salinity, to herbicides, parasitic plants, frost or heat. In this way we might circumvent a natural tendency for high yield and low production cost to effectively select against the best human nutrition. Here we discuss the need and means for agriculture, food processing, food transport, sociology, nutrition and medicine to be integrated into new approaches to food production with optimal human nutrition as a principle goal.

    Parenteral nutrition (PN) provides nourishment and hydration as an intravenous infusion to patients with intestinal failure (IF). The aim of the study is to generate theory that explains the experiences of adult patients living with home parenteral nutrition (HPN) and complex medication regimens. A grounded theory methodology was used to explore the experiences of twelve patients receiving HPN. A semi-structured interview was conducted and recorded in each participant's home setting. Each interview was transcribed verbatim. The simultaneous process of data collection and analysis was followed reflecting the principles of the constant comparative approach. A total of 15 patients gave written consent, with 12 of them agreeing to be interviewed. All the participants had previously undergone surgery as a result of chronic ill health or sudden illness. Analysis revealed two core categories: stoma and HPN, and these were supported by the subcategories: maintaining stoma output, access to toilets, managing dietary changes, maintaining the HPN infusion routine, access to technical help to set up an HPN infusion, mobility with HPN equipment and general health changes. The strategy of living with loss was demonstrated by all the participants, and this was supported by the action strategies of maintaining daily activities and social interactions. This study generates new understanding and insight into the views and experiences of patients receiving HPN in the UK. The findings from these participants have been shown to resonate with the Kubler-Ross Model [1] of the five stages of grief. The theory of living with loss was generated by the use of a grounded theory methodology. This small scale exploratory study reveals opportunities for improvements in practice to be considered by the nutrition support team (NST) and other healthcare professionals involved in the patient's hospital stay prior to discharge on HPN.

  12. Cyclodextrins in Food Technology and Human Nutrition: Benefits and Limitations.

    Science.gov (United States)

    Fenyvesi, É; Vikmon, M; Szente, L

    2016-09-09

    Cyclodextrins are tasteless, odorless, nondigestible, noncaloric, noncariogenic saccharides, which reduce the digestion of carbohydrates and lipids. They have low glycemic index and decrease the glycemic index of the food. They are either non- or only partly digestible by the enzymes of the human gastrointestinal (GI) tract and fermented by the gut microflora. Based on these properties, cyclodextrins are dietary fibers useful for controlling the body weight and blood lipid profile. They are prebiotics, improve the intestinal microflora by selective proliferation of bifidobacteria. These antiobesity and anti-diabetic effects make them bioactive food supplements and nutraceuticals. In this review, these features are evaluated for α-, β- and γ-cyclodextrins, which are the cyclodextrin variants approved by authorities for food applications. The mechanisms behind these effects are reviewed together with the applications as solubilizers, stabilizers of dietary lipids, such as unsaturated fatty acids, phytosterols, vitamins, flavonoids, carotenoids and other nutraceuticals. The recent applications of cyclodextrins for reducing unwanted components, such as trans-fats, allergens, mycotoxins, acrylamides, bitter compounds, as well as in smart active packaging of foods are also overviewed.

    The use of palm oil by the food industry is increasingly criticized, especially in Italy, for its purported negative effects on human health and environment. This paper summarizes the conclusions of a Symposium on this topic, gathered by the Nutrition Foundation of Italy, among experts representing a number of Italian Medical and Nutritional Scientific Societies. Toxicological and environmental issues were not considered. Participants agreed that: no evidence does exist on the specific health effects of palm oil consumption as compared to other saturated fatty acids-rich fats; the stereospecific distribution of saturated fatty acids in the triacylglycerol molecule of palm oil limits their absorption rate and metabolic effects; in agreement with International guidelines, saturated fatty acids intake should be kept palm oil consumption on human health (and specifically on CVD or cancer risk) can be foreseen.

  15. The nutritive and immunoprotective quality of human milk beyond 1 year postpartum: are lactation-duration-based donor exclusions justified?

    Science.gov (United States)

    Perrin, Maryanne Tigchelaar; Fogleman, April; Allen, Jonathan C

    2013-08-01

    Donor human milk is critical for the fragile preterm infant who does not have access to his or her mother's milk, improving survival rates and quality of survival and decreasing hospital stay. Despite the opening of donor milk banks around the world, shortages continue as demand for donor milk exceeds supply. One potential means of increasing supply is by reducing exclusion criteria that prohibit mothers from donating milk based on duration of lactation. Minimal research has been done on the composition of human milk during the second year of lactation, with most research focusing on the nutritive compounds and not the immunoprotective compounds. Several immunoprotective compounds, including lysozyme, lactoferrin, secretory immunoglobulin A, and oligosaccharides, are abundant in human milk compared to bovine-based infant formula and are partially or fully retained during Holder pasteurization, making them an important differentiating feature of donor milk. A PubMed search was conducted to review studies in human milk composition during the second year of lactation. Limitations of existing research include sample collection protocols, small study sizes, and use of populations that may have been at risk for nutritional deficiencies. Stable concentrations of several components were reported including protein, lactose, iron, copper, lactoferrin, and secretory immunoglobulin A. Lysozyme concentration increased during extended lactation, while zinc and calcium concentrations declined into the second year. Conflicting findings were reported on fat content, and no information was available regarding oligosaccharide content. More research is needed to create evidence-based guidelines regarding the nutritive and immunoprotective value of donor milk throughout the course of lactation.

    Blood hemoglobin, serum iron, total iron binding capacity (TIBC) and serum ferritin were measured in 140 healthy rural mapuche (southern Chile's indigenous ethnic group) infants aged 8 to 15 months: 90 had been exclusively breast fed for the first 5 or 6 months of life, then solid foods were introduced but cow's milk was never given to them. The remaining 50, which were all weaned at nearly 4 months of age and then given cow's milk and solid foods at the corresponding age, were designated as controls. Anemia was detected in 4.5% of breast fed infants and in 38% of controls. Evidence of iron deficient erythropoiesis was found in 5% and 81% of cases and controls, respectively. Human milk apparently protects this ethnic group from iron deficiency anemia and this protection seems to be better in mapuche infants than in other groups of chilean infants, because these late have shown 30% incidence of anemia around the first year of life in other studies. More studies on differences in iron nutritional state among mapuche and non mapuche are needed and are under way.

    Lane, H. W.; LeBlanc, A. D.; Putcha, L.; Whitson, P. A.

    1993-01-01

    Space flight provides a model for the study of healthy individuals undergoing unique stresses. This review focuses on how physiological adaptations to weightlessness may affect nutrient and food requirements in space. These adaptations include reductions in body water and plasma volume, which affect the renal and cardiovascular systems and thereby fluid and electrolyte requirements. Changes in muscle mass and function may affect requirements for energy, protein and amino acids. Changes in bone mass lead to increased urinary calcium concentrations, which may increase the risk of forming renal stones. Space motion sickness may influence putative changes in gastro-intestinal-hepatic function; neurosensory alterations may affect smell and taste. Some or all of these effects may be ameliorated through the use of specially designed dietary countermeasures.

    2007-09-25

    Milk and milk products are nutritious food items containing numerous essential nutrients, but in the western societies the consumption of milk has decreased partly due to claimed negative health effects. The content of oleic acid, conjugated linoleic acid, omega-3 fatty acids, short- and medium chain fatty acids, vitamins, minerals and bioactive compounds may promote positive health effects. Full-fat milk has been shown to increase the mean gastric emptying time compared to half-skimmed milk, thereby increasing the gastrointestinal transit time. Also the low pH in fermented milk may delay the gastric emptying. Hence, it may be suggested that ingesting full-fat milk or fermented milk might be favourable for glycaemic (and appetite?) regulation. For some persons milk proteins, fat and milk sugar may be of health concern. The interaction between carbohydrates (both natural milk sugar and added sugar) and protein in milk exposed to heat may give products, whose effects on health should be further studied, and the increasing use of sweetened milk products should be questioned. The concentration in milk of several nutrients can be manipulated through feeding regimes. There is no evidence that moderate intake of milk fat gives increased risk of diseases.

  20. Nutritional Genomics and the Mediterranean Diet’s Effects on Human Cardiovascular Health

    Directory of Open Access Journals (Sweden)

    Montserrat Fitó

    2016-04-01

    Full Text Available The synergies and cumulative effects among different foods and nutrients are what produce the benefits of a healthy dietary pattern. Diets and dietary patterns are a major environmental factor that we are exposed to several times a day. People can learn how to control this behavior in order to promote healthy living and aging, and to prevent diet-related diseases. To date, the traditional Mediterranean diet has been the only well-studied pattern. Stroke incidence, a number of classical risk factors including lipid profile and glycaemia, emergent risk factors such as the length of telomeres, and emotional eating behavior can be affected by genetic predisposition. Adherence to the Mediterranean diet could exert beneficial effects on these risk factors. Our individual genetic make-up should be taken into account to better prevent these traits and their subsequent consequences in cardiovascular disease development. In the present work, we review the results of nutritional genomics explaining the role of the Mediterranean diet in human cardiovascular disease. A multidisciplinary approach is necessary to extract knowledge from large-scale data.

  1. The use of stable isotopes as minerals tracers in human nutrition research

    Sajet, A. S.

    2007-01-01

    The idea of using stable isotopes as tracers in metabolic studies of vital systems started when it was noted that stable isotopes have the ability to unite with biomolecules.The article aims to review the methods used to measure quantities of tracer in doses given to donors orally or via intravenous injection, determinants of detection and their estimation as well as the use of mass spectrometer and other devices to measure different stable isotopes. In fact, the use of stable isotopes in nutrition research is an essential technique in order to understand many of the processes related to minerals absorption and the human body composition of water, fat and bones, transportation of food components within the body and estimation of the ages of red blood cells. It is possible to use the secretion of stable isotopes taken by injection to determine the paths of excretion or estimate self-retaining material by the intestine. The stable isotope technology helps to know the mechanics of minerals absorption and excretion in the body. It was possible to find out metabolic reactions of metals using mathematical models based on the measurement of tracers amount in biological fluids in order to know the absorbance situation of metals in the body.

    Patients starting noninvasive ventilation (NIV) to treat acute respiratory failure are often unable to eat and therefore remain in the fasting state or receive nutritional support. Maintaining a good nutritional status has been reported to improve patient outcomes. In the present study, our primary objective was to describe the nutritional management of patients starting first-line NIV, and our secondary objectives were to assess potential associations between nutritional management and outcomes. Observational retrospective cohort study of a prospective database fed by 20 French intensive care units. Adult medical patients receiving NIV for more than 2 consecutive days were included and divided into four groups on the basis of nutritional support received during the first 2 days of NIV: no nutrition, enteral nutrition, parenteral nutrition only, and oral nutrition only. Of the 16,594 patients admitted during the study period, 1075 met the inclusion criteria; of these, 622 (57.9%) received no nutrition, 28 (2.6%) received enteral nutrition, 74 (6.9%) received parenteral nutrition only, and 351 (32.7%) received oral nutrition only. After adjustment for confounders, enteral nutrition (vs. no nutrition) was associated with higher 28-day mortality (adjusted HR, 2.3; 95% CI, 1.2-4.4) and invasive mechanical ventilation needs (adjusted HR, 2.1; 95% CI, 1.1-4.2), as well as with fewer ventilator-free days by day 28 (adjusted relative risk, 0.7; 95% CI, 0.5-0.9). Nearly three-fifths of patients receiving NIV fasted for the first 2 days. Lack of feeding or underfeeding was not associated with mortality. The optimal route of nutrition for these patients needs to be investigated.

    To compare the nutritional components of genetically modified rice expressing human lactoferrin (hLf) with its parental rice, and to observe the sub-chronic toxicity of hLf rice. The nutritional components of hLf rice and its parental rice were determined by the National Standard Methods. Eighty weanling Wistar rats were randomly divided into 4 groups based on their gender and body weight: group A (hLf rice high-dose group with 71.45% rice), group B (hLf rice medium-dose group with 35. 725% rice), group C (parental rice group with 71.01% rice) and group D (AIN-93G diet group), and the latter two groups were used as the control. Body weight, dietary intake, blood routine test, blood biochemical examination, organ coefficient, bone density and the pathology of organs were investigated at the end of a 90-day feeding experiment. Except for human lactoferrin and Fe, there was no difference of main nutritional components, minerals and vitamins between groups. The differences of some indicators of blood routine (WBC, HGB, RBC and MCH), blood biochemistry (AST and GLU), organ coefficient and bone density between group A and B (hLf rice) with group C (parental rice) or group D (AIN-93G) were significant, while no difference of other indicators. Although some differences were observed, all indicators were still in the normal reference range. Therefore, there was no sign of toxic and adverse effects for hLf rice on rats.

    The Office of Exploration has established a process whereby all NASA field centers and other NASA Headquarters offices participate in the formulation and analysis of a wide range of mission strategies. These strategies were manifested into specific scenarios or candidate case studies. The case studies provided a systematic approach into analyzing each mission element. First, each case study must address several major themes and rationale including: national pride and international prestige, advancement of scientific knowledge, a catalyst for technology, economic benefits, space enterprise, international cooperation, and education and excellence. Second, the set of candidate case studies are formulated to encompass the technology requirement limits in the life sciences, launch capabilities, space transfer, automation, and robotics in space operations, power, and propulsion. The first set of reference case studies identify three major strategies: human expeditions, science outposts, and evolutionary expansion. During the past year, four case studies were examined to explore these strategies. The expeditionary missions include the Human Expedition to Phobos and Human Expedition to Mars case studies. The Lunar Observatory and Lunar Outpost to Early Mars Evolution case studies examined the later two strategies. This set of case studies established the framework to perform detailed mission analysis and system engineering to define a host of concepts and requirements for various space systems and advanced technologies. The details of each mission are described and, specifically, the results affecting the advanced technologies required to accomplish each mission scenario are presented.

    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.

    There is lack of consensus on how nutritional screening and intervention should be provided to cancer patients. Nutritional screening and support of cancer patients are not well established in the Middle East. We report our systematic and practical experience led by a qualified specialist dietician in a cancer inpatient setting, using a novel nutritional screening tool. Ninety-seven consecutive inpatients underwent nutritional screening and categorised into three nutritional risk groups based on oral intake, gastrointestinal symptoms, body mass index (BMI) and weight loss. Nutritional support was introduced accordingly. Statistical tests used included ANOVA, Bonferroni post hoc, chi-square and log rank tests. Median age was 48 (19-87)years. Patients were categorised into three nutritional risk groups: 55 % low, 37 % intermediate and 8 % high. Nutritional intervention was introduced for 36 % of these patients. Individually, weight, BMI, oral intake, serum albumin on admission and weight loss significantly affected nutritional risk and nutritional intervention (all significant P values). Eighty-seven, 60 and 55 % of patients admitted for chemotherapy, febrile neutropenia and other reasons, respectively, did not require specific nutritional intervention. There was a statistically significant relationship between nutritional risk and nutritional intervention (P=0.005). Significantly more patients were alive at 3 months in low (91 %) than intermediate (75 %) than high (37 %)-risk groups. About a third of cancer inpatients require nutritional intervention. The adopted nutritional risk assessment tool is simple and practical. The validity of this tool is supported by its significant relation with known individual nutritional risk factors. This should be confirmed in larger prospective study and comparing this new tool with other established ones.

    Full Text Available Background. A module on nutrition, human rights and governance was developed and presented jointly by academic institutions in Norway, South Africa and Uganda, under the NOrway MAsters (NOMA programme, for their respective Master’s degree programmes in nutrition. Consisting of three study units, it was presented consecutively in the three countries, with each study unit building on the previous one.Objectives. To document the perceptions of participating students on various aspects of the module, informing future curriculum endeavours.Methods. A mixed methods approach was followed. A module evaluation form completed by students for each study unit was analysed. In-depth telephonic interviews were voice recorded and transcribed. Through an inductive process, emerging themes were used to compile a code list and content analysis of the unstructured data.Results. An overall positive module evaluation by 20 participants (91% response rate can be ascribed to the module content, enlightening study visits, expertise of lecturers and an interactive teaching style. Logistical issues regarding time management and administrative differences among the academic institutions caused some concerns. Students experienced some resistance against qualitative research in natural science faculties. Students benefited from being exposed to different teaching styles and education systems at universities in differentcountries. Constructive alignment of teaching and learning activities could be optimised through involvement and empowerment of all relevant lecturers.Conclusion. Successful implementation of the module not only provides nutrition Master’s students with knowledge to operationalise a human rights-based approach during future interactions in their professional practice, but also serves as an example of the benefits and challenges of interdisciplinary and transnational collaboration in module development.

  9. The application of near infrared spectroscopy in nutritional intervention studies

    Full Text Available 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 haemodynamic 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 endeavouring 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.

    Full Text Available BackgroundNutrition behaviors of adolescent girls is of serious health concerns. Although nutrition education interventions in Iran have met with some success, most of them could not promote nutrition behavioral changes. The aim of our study is to determine a school-based nutrition education intervention to improve adolescents’ nutrition behaviors and behavioral mediators based on the social cognitive theory (SCT.Materials and MethodsThis study is a single-blind randomized controlled trial. Eligible participants will be all student girls in grade 6 and 7, their parents and teachers in Isfahan governmental schools. This multi com­ponent school-based intervention include adolescents’ nutrition education package, parents’ nutrition massages, participatory homework, parents and teachers nutrition education package, supportive group, and collaboration with decision makers. Changing in nutrition behaviors including breakfast, fruit and vegetable, snack and fast food consumption will be examined, as primary outcome. Secondary outcome will be behavioral mediators such as knowledge, self-efficacy, intention, situation, self-regulation, social support, outcome expectations and expectancies, in adolescent girls. The outcomes will be assessed at baseline, and after 3 and 6-month follow-up.DiscussionThis study evaluates a school-based, guided SCT intervention, designed to improve healthy dietary behaviors, nutrition knowledge of adolescent girls. Few behavioral interventions have targeted this high-risk population in Iran. The intervention seems to be promising and has the potential to bridge the gap of the limited program outcomes of nutrition education in Iranian adolescents.

    Fibroblast growth factor 21 (FGF21) has recently emerged as a metabolic hormone involved in regulating glucose and lipid metabolism in mouse, but the regulatory mechanisms and actions of FGF21 in humans remain unclear. Here we have investigated the regulatory mechanisms of the human FGF21 gene at the transcriptional level. A deletion study of the human FGF21 promoter (−1672 to +230 bp) revealed two fasting signals, including peroxisome proliferator-activated receptor α (PPARα) and glucagon signals, that independently induced human FGF21 gene transcription in mouse primary hepatocytes. In addition, two feeding signals, glucose and xylitol, also dose-dependently induced human FGF21 gene transcription and mRNA expression in both human HepG2 cells and mouse primary hepatocytes. FGF21 protein expression and secretion were also induced by high glucose stimulation. The human FGF21 promoter (−1672 to +230 bp) was found to have a carbohydrate-responsive element at −380 to −366 bp, which is distinct from the PPAR response element (PPRE). Knock-down of the carbohydrate response element binding protein by RNAi diminished glucose-induced human FGF21 transcription. Moreover, we found that a region from −555 to −443 bp of the human FGF21 promoter region exerts an important role in the activation of basic transcription. In conclusion, human FGF21 gene expression is paradoxically and independently regulated by both fasting and feeding signals. These regulatory mechanisms suggest that human FGF21 is increased with nutritional crisis, including starvation and overfeeding. PMID:21829679

    Nutritional factors such as casein hydrolysates and long chain polyunsaturated fatty acids have been proposed to exert beneficial metabolic effects. We aimed to investigate how a casein hydrolysate (eCH) and long chain polyunsaturated fatty acids could affect human primary adipocyte function in vitro. Incubation conditions with the different nutritional factors were validated by assessing cell vitality with lactate dehydrogenase (LDH) release and neutral red incorporation. Intracellular triglyceride content was assessed with Oil Red O staining. The effect of eCH, a non-peptidic amino acid mixture (AA), and long-chain polyunsaturated fatty acids (LC-PUFAs) on adiponectin and leptin secretion was determined by enzyme-linked immunosorbent assay (ELISA). Intracellular adiponectin expression and nuclear factor-κB (NF-κB) activation were analyzed by Western blot, while monocyte chemoattractant protein-1 (MCP-1) release was explored by ELISA. The eCH concentration dependently increased adiponectin secretion in human primary adipocytes through its intrinsic peptide bioactivity, since the non-peptidic mixture, AA, could not mimic eCH’s effects on adiponectin secretion. Eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and DHA combined with arachidonic acid (ARA) upregulated adiponectin secretion. However, only DHA and DHA/ARA exerted a potentanti-inflammatory effect reflected by prevention of tumor necrosis factor-α (TNF-α) induced NF-κB activation and MCP-1 secretion in human adipocytes. eCH and DHA alone or in combination with ARA, may hold the key for nutritional programming through their anti-inflammatory action to prevent diseases with low-grade chronic inflammation such as obesity or diabetes.

    The increasing consumption of nutritional supplements among the people mainly aiming at the replacement of nutrients and minerals in the organism has led the commercialization of a great number of brands of these products. Consequently the quality control of these products is of great interest to verify if their element contents agree the values presented in labels or in the instructions for their uses. In this study the elements Ca, Co, Cr, Cu, Fe, K, Na, Se and Zn were analyzed in multimineral supplements and vitamins samples using neutron activation analysis method. The results obtained compared with the values of the labels of nutritional supplements presented good agreement. For quality control of the analytical data, certified reference materials NIST 1400 Bone Ash and NIST 1633b Coal Fly Ash provided by National Institute of Standards and Technology were analysed. Accuracy and precision of the results were evaluated and Z score values obtained were lower than 2 indicating that the data found are within the certified values at 95% of significance level.

    Early childhood caries is a persistent worldwide problem. The etiologic contribution of feeding practices has been less frequently investigated in prospective studies of young children. The Porto Alegre Early Life Nutrition and Health Study has followed a birth cohort of 715 mother-child pairs, recruited from municipal health centers, originally involved in a cluster-randomized controlled trial of healthcare worker training. The birth cohort links prospectively collected socio-demographic, infant feeding, and general and oral health information. To date, oral health data, including caries status and oral health-related quality of life, have been collected for 458 children at the age of 2-3 years. Studies are underway to investigate possible determinants and consequences of oral health among these children.

  17. On the role and fate of sugars in human nutrition and health. Introduction.

    2009-03-01

    The recently implemented European Regulation (EC) No. 1924/2006 on nutrition and health claims made on foods is fuelling scientific research efforts in the food and health arena. Essentially, it is now established that only claims that are scientifically substantiated will be allowed. Because this new legislation covers the idea that foods with health or nutritional claims might be perceived by consumers as having a health advantage over products without claims, it introduces a further requirement (enclosing the new concept of 'nutrient profile') to avoid a situation where claims could mislead consumers when trying to make healthy choices in the context of a balanced diet. Thus, only those foods having an appropriate nutrition profile (composition of different nutrients such as sugars and other substances with particularly relevant nutritional or physiological effects) will be allowed to bear claims. A scientific expert workshop was organized to critically review the available evidence behind current intake recommendations for sugars, focusing on the strength/gaps of the scientific evidence available and the identification of those fields where further research is needed. Work was distributed in the following topics covering potential effects of dietary sugars on (i) body weight control; (ii) diabetes-insulin resistance; (iii) dental health and (iv) micronutrient dilution. New approaches, including intervention studies and the application of nutrigenomic technologies, should be undertaken and interpreted bearing in mind that foods, food components and their combinations can have both positive and negative effects on health, thus requiring benefit-risk analysis.

    Nutrition transition is an adverse outcome of rapid economic development and globalization. The present review documents the pattern of nutrition and health transition among different food groups leading to the growing global and national epidemic of non-communicable diseases (NCDs). Studies published in various national and international journals were searched using PubMed and Google Scholar search engines from the year 2000 to 2015. Literature was reviewed to gather data pertaining to nutrition and health transition and economic burden of non-communicable disease (NCDs). Diets are changing globally towards higher intakes of simple and refined carbohydrates (including sugar), fat and lower intake of complex carbohydrates. The upsurge of co-morbidities arising from nutrition transition is a serious threat worldwide especially in developing countries like India, which in turn poses a huge impact on economic development of the nation. Better awareness and encouragement of using healthier diet option can help to combat the epidemic of NCDs in the developing world.

    This research involves the nutritional characterization of the most commonly cultivated fish in the region. The species under study were: Rainbow trout (Salmo gairdnerii), tilapia roja (Oreocliromis sp), cachama blanca (Piaractus brachypomus), bocachico (Prochilodus reticulatus magdalenae) and catfish (Pseudoplatystoma faciatum). A sea fish, coho Salmon (Oncorhynchus kisutch), was used as reference because it is the imported species most used in the region, and it also contains n-3 fatty acids. For each fish sample moisture, ash, protein content, total fat, minerals (iron, calcium and phosphorous) and a fatty acid profile were determined. Results show a total protein content in between 16.4 and 22.6 g/100 g fillet for fresh water fish. Total fat amounts for trout are the highest (8.1 g/100 g fillet), while catfish has the lowest fat content (0.4 g/100 g fillet). Trout was found to be the most important source of n-3 fatty acids (EPA+DHA) and phosphorous, with values ranging from 0.25% to 0.52%, and 250 to 346 mg/100 g fillet, respectively. Catfish and trout exhibited the highest iron content, with values ranging from 3 to 6mg/100 g fillet. Salmon, on the other hand, showed a high n-3 fatty acid content of 1.16% to 2.25%, when compared to fresh water fish. Calcium content is low in all species under scrutiny. Fresh water fish, other than trout, show no significant amount of n-3 fatty acids. However, all of them are a good source of protein. The obtained results allowed to determine the profile of oily acids of produced fish for human consumption in the region, demonstrating that the trout is the species with major quantity of oily acids n-3 specially DHA and of the minerals the phosphorus. Other species (kinds) catfish, bocachico, tilapia and cachama, are not a source of oily acids n-3, but they are an important source of protein.

    In achieving adequate nutrition for all people in the world foods of animal origin are indispensable to supply sufficient protein and essential nutrients. All foods of animal origin have a number of characteristics in common, in view of which they should be regarded as highly valuable human food because of the considerable biological value of the proteins, their ready digestibility and their palatability. A number of nutritional features of animal versus vegetable protein are discussed. Several queries have to be placed against the health aspects of the copious consumption of animal protein as has increasingly become the practice in Europe. The consumption of dishes prepared from food of animal origin high in protein will inevitably be associated with a high fat content. It is not likely that, specifically, the incidence of human cancer will also be increased by the allegedly carcinogenic effects of meat persé, however using nitrite in meats may be hazardous when consumption of meat is considerable because of the carcinogenic effects of nitrosamines. In addition, there are drawbacks to the copious consumption of food of animal origin as part of the daily diet because of the high fat content and low dietary fibre content of this food. A conference of managers in the animal-food industry and experts from the professional medical and dietetic organizations would be a desirable improvement in achieving an optimum situation. Sufficient production and distribution will not fully ensure adequate nutrition of animal origin. Its valuable nutrients must be available from food which is acceptable to the individual consumer. Those factors which decide what is eaten and why, are not known to a sufficient extent. Cultural and environmental factors also play a highly decisive role in the matter. There are religious rules regarding food of animal origin, which obtain for large sections of the population all over the world. Other practices concerning the consumption of food of

    Recent studies on the optimal modalities to feed patients during the ICU stay show divergent results. The level and the timing of energy provision is a critical issue, associated with the clinical outcome. These results questioned the clinical relevance of the recent guidelines issued by American, Canadian and European academic societies. Four recent prospective randomized studies enrolled critically ill patients who received various nutritional regimens and tested the effect of nutritional support on outcome. The Tight Calorie balance Control Study (TICACOS) targeted on calorie administration according to measured energy expenditure and found increased ICU morbidity but improved hospital mortality. The large EpaNIC study compared 'early' with 'late' (parenteral nutrition) nutrition, mostly in patients after cardiac surgery, and found an increased morbidity associated with early parenteral nutrition. The supplemental parenteral nutrition (SPN) study randomized the patients after 3 days and targeted the calories administered by parenteral nutrition as a complement to unsuccessful enteral nutrition using indirect calorimetry. The SPN resulted in less nosocomial infections and shorter duration of mechanical ventilation. Finally, a recent Australian study enrolled patients unable to be early fed enterally to receive, or not, parenteral nutrition targeted at 1500 kcal. No complications were noted in the parenteral nutrition group. Lessons from all these studies are summarized and should help in designing better studies and guidelines. The critical analysis of recent prospective studies comparing various levels of calorie administration, enteral versus parenteral nutrition and enteral versus SPN confirms the recommendations to avoid underfeeding and overfeeding. Parenteral nutrition, required if enteral feeding is failing, and if adjusted up to a measured optimal level, may improve outcome. More studies on the optimal level of energy and protein administration to

    Full Text Available The positive nutritional effects of PUFA in the human diet nowadays are wellknown. The presence of PUFA in food of animal origin is first of all influenced by the feeding. The animal feeds rich in omega-3 PUFA are considered as basic feeds, such as meadow, grass, hay, green forage, grains etc. In the newly accessed EU countries the traditional breeding methods are typical (housing, lairage, pasture. This tendency is reflected also in the composition of local breeds: the so called indigenous, traditional breeds are characteristic. The development and expansion of local breeding methods is of crucial importance for the viable region, the protection (many times the restoration of environment and for the above mentioned human nutritional advantages. With modern control methods of origin, with adherence of food-safety rules, the local commercialization of the traditional foods can be solved, as many positive examples show in different countries. The need for diverse, tasteful and safe products of special quality is also increasing. Our aim is to support and favour the local, traditional breeding for direct commercialization with ensuring the proper conditions, financial support and legislation.

    To build up sufficient knowledge of a 'healthy diet'. Here, we report on the assessment of nutritional knowledge using a uniform method in a large sample of adolescents across Europe. A cross-sectional study. The European multicentre HELENA (Healthy Lifestyle in Europe by Nutrition in Adolescence) study conducted in 2006-2007 in ten cities in Austria, Belgium, France, Germany, Greece (one inland and one island city), Hungary, Italy, Spain and Sweden. A total of 3546 adolescents (aged 12·5-17·5 years) completed a validated nutritional knowledge test (NKT). Socio-economic variables and anthropometric data were considered as potential confounders.

    Full Text Available Abstract Background Nutrition is often a casualty of the busy work day for physicians. We aimed to explore physicians' views of their nutrition in the workplace including their perceptions of the impact of inadequate nutrition upon their personal wellness and their professional performance. Methods This is a qualitative study of a sample of 20 physicians practicing in a large urban teaching hospital. Semi-structured open ended interviews were conducted to explore physicians' views of workplace nutrition. The same physicians had agreed to participate in a related nutrition based wellness intervention study that compared nutritional intake and cognitive function during a day of usual nutrition patterns against another day with scheduled nutrition breaks. A second set of interviews was conducted after the intervention study to explore how participation in the intervention impacted these views. Detailed interview content notes were transcribed and analyzed independently with differences reconciled by discussion. Results At initial interview, participants reported difficulty accessing adequate nutrition at work, linking this deficit with emotional (irritable and frustrated, physical (tired and hungry, and cognitive (difficulty concentrating and poor decision making symptoms. In addition to identifying practical barriers such as lack of time to stop and eat, inconvenient access to food and poor food choices, the physicians described how their sense of professionalism and work ethic also hinder their work nutrition practices. After participating in the intervention, most physicians reported heightened awareness of their nutrition patterns and intentions to improve their workplace nutrition. Conclusions Physicians report that inadequate workplace nutrition has a significant negative impact on their personal wellness and professional performance. Given this threat to health care delivery, health care organizations and the medical profession need to

    The multidisciplinary nature of nutrition research is one of its main strengths. At the same time, however, it presents a major obstacle to integrate data analysis, especially for the terminological and semantic interpretations that specific research fields or communities are used to. To date, a proper ontology to structure and formalize the concepts used for the description of nutritional studies is still lacking. We have developed the Ontology for Nutritional Studies (ONS) by harmonizing selected pre-existing de facto ontologies with novel health and nutritional terminology classifications. The ONS is the result of a scholarly consensus of 51 research centers in nine European countries. The ontology classes and relations are commonly encountered while conducting, storing, harmonizing, integrating, describing, and searching nutritional studies. The ONS facilitates the description and specification of complex nutritional studies as demonstrated with two application scenarios. The ONS is the first systematic effort to provide a solid and extensible formal ontology framework for nutritional studies. Integration of new information can be easily achieved by the addition of extra modules (i.e., nutrigenomics, metabolomics, nutrikinetics, and quality appraisal). The ONS provides a unified and standardized terminology for nutritional studies as a resource for nutrition researchers who might not necessarily be familiar with ontologies and standardization concepts.

    How many calories are used when a nursing mother feeds her infant? How much milk does an infant receive in one week? What is the impact of the environment on the energy needs of children? How adequately does dietary protein sustain the synthesis of body constituents? What types of foods best nourish a child recovering from intestinal diseases such as diarrhoea? Quantitative answers to questions such as these can be obtained from the use of stable, non-radioactive isotopic tracers. Answers to these questions are important in assessing the nutritional status of infants, children, pregnant women and nursing mothers, as well as that of individuals who subsist on marginal food supplies. Because stable isotopic tracers are completely safe and without hazard, they can be used freely in health, nutrition, and agriculture studies in all populations

    Full Text Available The Department of Basic Education (DBE has not given nutrition education the necessary emphasis that it needs, despite its importance in South African schools. Nutrition is included as only one of many topics forming part of the Life Orientation syllabus. Educators are role models for learners in making healthy food choices, however, studies have shown that major gaps exist in the health and nutrition-related knowledge and behaviour of educators. The objective of this research was to undertake a pilot study to determine the impact of a nutrition education programme (NEP on the nutrition knowledge of Life Orientation educators in public schools in South Africa (SA. An exploratory baseline survey, to determine the nutrition education practices in 45 purposively selected public schools, was carried out before the experimental nutrition education intervention study. A nutrition knowledge questionnaire was completed by 24 purposively selected educators, representing all nine provinces in SA, before and after a three-day NEP. Pre and post-NEP data were analysed on the Statistical Package for Social Sciences (SPSS for a Windows program version 17.0 for descriptive statistics, version 17.0. Paired t-tests measured statistically significant differences (p < 0.05 before and after the NEP. The knowledge of the respondents improved significantly after the NEP as the mean±s.d. score of correctly answered questions (n = 59 improved from 63.3±30.2% before to 80.6±21.1% after the NEP. The results proved that nutrition knowledge of Life Orientation educators in primary schools is not optimal, but can be improved by NEP.

    Obesity is the most common metabolic disease whose prevalence is increasing worldwide. This condition is considered a serious public health problem due to associated comorbidities such as diabetes mellitus and hypertension. Perinatal morbidity related to obesity does not end with birth; this continues affecting the mother/infant binomial and could negatively impact on metabolism during early infant nutrition. Nutrition in early stages of growth may be essential in the development of obesity in adulthood, supporting the concept of "nutritional programming". For this reason, breastfeeding may play an important role in this programming. Breast milk is the most recommended feeding for the newborn due to the provided benefits such as protection against obesity and diabetes. Health benefits are based on milk components such as bioactive molecules, specifically hormones involved in the regulation of food intake. Identification of these molecules has increased in recent years but its action has not been fully clarified. Hormones such as leptin, insulin, ghrelin, adiponectin, resistin, obestatin and insulin-like growth factor-1 copeptin, apelin, and nesfatin, among others, have been identified in the milk of normal-weight women and may influence the energy balance because they can activate orexigenic or anorexigenic pathways depending on energy requirements and body stores. It is important to emphasize that, although the number of biomolecules identified in milk involved in regulating food intake has increased considerably, there is a lack of studies aimed at elucidating the effect these hormones may have on metabolism and development of the newborn. Therefore, we present a state-of-the-art review regarding bioactive compounds such as hormones secreted in breast milk and their possible impact on nutritional programming in the infant, analyzing their functions in appetite regulation.

    Malnutrition in hospitalized patients is associated with an increased risk of death, in both the short and the long term. The purpose of this study was to determine which nutrition-related risk index predicts long-term mortality better (three years) in patients who receive total parenteral nutrition (TPN). This prospective, multicenter study involved noncritically ill patients who were prescribed TPN during hospitalization. Data were collected on Subjective Global Assessment (SGA), Nutritional Risk Index (NRI), Geriatric Nutritional Risk Index (GNRI), body mass index, albumin and prealbumin, as well as long-term mortality. Over the 1- and 3-year follow-up periods, 174 and 244 study subjects (28.8% and 40.3%) respectively, died. Based on the Cox proportional hazards survival model, the nutrition-related risk indexes most strongly associated with mortality were SGA and albumin (Nutrition and Metabolism. All rights reserved.

    As the credential for nutrition counselor with professional skills and knowledge for invalids, who also provides the nutrition education for local residence at the administrative organization, the qualification system of registered dietitian has been established in Japan. Additionally, in accordance with the legislation of Basic Act on Food Education and the revision of School Education Law, the Diet and Nutrition Teacher System has established in 2005. Therefore, registered dietitian has been approved to teach at the elementary school or junior high school as a teacher. Since registered dietitian is the educator of the “diet and nutrition,” it is important to provide proper knowledge of food irradiation at the training facility for registered dietitian. This report describes the instruction of food irradiation at the education curriculum of the registered dietitian training course. In addition, questionnaire survey result on the knowledge of food irradiation gathered from newly-enrolled students in the registered dietitian training course will also be reported. (author)

  16. Resource conflict and cooperation between human host and gut microbiota: implications for nutrition and health.

    Science.gov (United States)

    Wasielewski, Helen; Alcock, Joe; Aktipis, Athena

    2016-05-01

    Diet has been known to play an important role in human health since at least the time period of the ancient Greek physician Hippocrates. In the last decade, research has revealed that microorganisms inhabiting the digestive tract, known as the gut microbiota, are critical factors in human health. This paper draws on concepts of cooperation and conflict from ecology and evolutionary biology to make predictions about host-microbiota interactions involving nutrients. To optimally extract energy from some resources (e.g., fiber), hosts require cooperation from microbes. Other nutrients can be utilized by both hosts and microbes (e.g., simple sugars, iron) in their ingested form, which may lead to greater conflict over these resources. This framework predicts that some negative health effects of foods are driven by the direct effects of these foods on human physiology and by indirect effects resulting from microbiome-host competition and conflict (e.g., increased invasiveness and inflammation). Similarly, beneficial effects of some foods on host health may be enhanced by resource sharing and other cooperative behaviors between host and microbes that may downregulate inflammation and virulence. Given that some foods cultivate cooperation between hosts and microbes while others agitate conflict, host-microbe interactions may be novel targets for interventions aimed at improving nutrition and human health. © 2016 The Authors.

    The micronutrients (vitamins and minerals) are required in small amounts but are essential for health, development, and growth. Micronutrient deficiencies, which affect over two billion people around the globe, are the leading cause of many ailments including mental retardation, preventable blindness, and death during childbirth. Fish is an important dietary source of micronutrients and plays important role in human nutrition. In the present investigation, micronutrient composition of 35 food fishes (includes both finfishes and shellfishes) was investigated from varying aquatic habitats. Macrominerals (Na, K, Ca, Mg) and trace elements (Fe, Cu, Zn, Mn, Se) were determined by either atomic absorption spectroscopy (AAS) or inductively coupled plasma mass spectrometry (ICP-MS)/atomic emission spectrometry (ICP-AES). Phosphorus content was determined either spectrophotometrically or by ICP-AES. Fat-soluble vitamins (A, D, E, K) were analyzed by high-performance liquid chromatography (HPLC). The analysis showed that, in general, the marine fishes were rich in sodium and potassium; small indigenous fishes (SIFs) in calcium, iron, and manganese; coldwater fishes in selenium; and the brackishwater fishes in phosphorous. The marine fishes Sardinella longiceps and Epinephelus spp. and the SIFs were rich in all fat-soluble vitamins. All these recommendations were made according to the potential contribution (daily value %) of the species to the recommended daily allowance (RDA). Information on the micronutrients generated would enhance the utility of fish in both community and clinical nutrition.

    Nowadays nutrigenetics and nutrigenomics are perceived as one of the most important research areas ensuring better understanding of an impact of nutrition on human health. Since such researches are interdisciplinary in type, there is a problem with their widespread acceptance and practical clinical application of obtained results. Understanding the new ideas and hypotheses published in researches on nutrigenetics/nutrigenomics requires some knowledge of genetics, biochemistry, molecular biology, and capabilities and limitations that are associated with the use of statistical and bioinformatic analysis, and above all „omics” research technologies (genomics, transcriptomics, proteomics, metabolomics). Highly efficient genome and proteome analysis techniques allow to obtain data necessary for profiling of an individual patient. The main problem is still our insufficient knowledge of cell physiology and biochemistry. The vast amount of information is obtained with the use of „omics” technologies what makes it difficult to interpret and infer. An unquestionable advantage of this type of research is the possibility to utilize system analysis (system biology) which is important in the context of a holistic interpretation of biological phenomena. This review is an attempt to present the main hypotheses and objectives which are carried out by researchers in nutrigenetics/nutrigenomics. This article describes the most important directions of research and anticipated results that are related to the practical use of nutritional genomics as well as the critical assessment of the possible impact of future developments on public health.

    The Middle East and North Africa region harbors significant proportions of stunting and wasting coupled with surging rates of non-communicable diseases (NCDs). Recent evidence identified nutrition during the first 1000 days of life as a common denominator not only for optimal growth but also for curbing the risk of NCDs later in life. The main objective of this manuscript is to describe the protocol of the first cohort in the region to investigate the association of nutrition imbalances early in life with birth outcomes, growth patterns, as well as early determinants of non-communicable diseases. More specifically the cohort aims to 1) examine the effects of maternal and early child nutrition and lifestyle characteristics on birth outcomes and growth patterns and 2) develop evidence-based nutrition and lifestyle guidelines for pregnant women and young children. A multidisciplinary team of researchers was established from governmental and private academic and health sectors in Lebanon and Qatar to launch the Mother and Infant Nutritional Assessment 3-year cohort study. Pregnant women (n = 250 from Beirut, n = 250 from Doha) in their first trimester are recruited from healthcare centers in Beirut, Lebanon and Doha, Qatar. Participants are interviewed three times during pregnancy (once every trimester) and seven times at and after delivery (when the child is 4, 6, 9, 12, 18, and 24 months old). Delivery and birth data is obtained from hospital records. Data collection includes maternal socio-demographic and lifestyle characteristics, dietary intake, anthropometric measurements, and household food security data. For biochemical assessment of various indicators of nutritional status, a blood sample is obtained from women during their first trimester. Breastfeeding and complementary feeding practices, dietary intake, as well as anthropometric measurements of children are also examined. The Delphi technique will be used for the development of the nutrition and lifestyle

    Full Text Available Banana inflorescences are popularly known as 'navels,' and they are used in Brazil as nutritional complements. However, the nutritional value of banana inflorescences (male flowers and bracts has never been studied. Therefore, plant material of Musa acuminata, cultivar "ouro", was collected in Rio de Janeiro state, Brazil, and then submitted to chemical procedures to determine its nutritional composition. The experiment was arranged a completely randomized design and performed in triplicate. The sample composition analysis showed percentual average value for moisture, protein, fat and ash as 8.21, 14.50, 4.04 and 14.43, respectively. The dehydrated inflorescences were found to contain a significant nutritive complement based on their high content of potassium (5008.26 mg / 100 g and fiber 49.83% (lignin, cellulose and hemicelluloses revealing important functional and nutritional properties.

  2. Mechanisms of dietary response in mice and primates: a role for EGR1 in regulating the reaction to human-specific nutritional content.

    Directory of Open Access Journals (Sweden)

    Kai Weng

    Full Text Available Humans have a widely different diet from other primate species, and are dependent on its high nutritional content. The molecular mechanisms responsible for adaptation to the human diet are currently unknown. Here, we addressed this question by investigating whether the gene expression response observed in mice fed human and chimpanzee diets involves the same regulatory mechanisms as expression differences between humans and chimpanzees.Using mouse and primate transcriptomic data, we identified the transcription factor EGR1 (early growth response 1 as a putative regulator of diet-related differential gene expression between human and chimpanzee livers. Specifically, we predict that EGR1 regulates the response to the high caloric content of human diets. However, we also show that close to 90% of the dietary response to the primate diet found in mice, is not observed in primates. This might be explained by changes in tissue-specific gene expression between taxa.Our results suggest that the gene expression response to the nutritionally rich human diet is partially mediated by the transcription factor EGR1. While this EGR1-driven response is conserved between mice and primates, the bulk of the mouse response to human and chimpanzee dietary differences is not observed in primates. This result highlights the rapid evolution of diet-related expression regulation and underscores potential limitations of mouse models in dietary studies.

    Yadav, Monika; Verma, Manoj Kumar; Chauhan, Nar Singh

    2018-03-01

    The human gut contains a plethora of microbes, providing a platform for metabolic interaction between the host and microbiota. Metabolites produced by the gut microbiota act as a link between gut microbiota and its host. These metabolites act as messengers having the capacity to alter the gut microbiota. Recent advances in the characterization of the gut microbiota and its symbiotic relationship with the host have provided a platform to decode metabolic interactions. The human gut microbiota, a crucial component for dietary metabolism, is shaped by the genetic, epigenetic and dietary factors. The metabolic potential of gut microbiota explains its significance in host health and diseases. The knowledge of interactions between microbiota and host metabolism, as well as modification of microbial ecology, is really beneficial to have effective therapeutic treatments for many diet-related diseases in near future. This review cumulates the information to map the role of human gut microbiota in dietary component metabolism, the role of gut microbes derived metabolites in human health and host-microbe metabolic interactions in health and diseases.

    Nutritional aspects are important for the prevention of diseases and disorders, and few studies have focused on the relationship between risk of work injury and nutritional variables. This study aimed to verify whether nutritional variables constitute risk factors for work-related accidents. 1,422 industrial workers (600 cases plus 822 controls). A case-control study was carried out in an industrial city in south-east Brazil. A multiple logistic regression model was adjusted using work-related accidents as the response variable and nutritional variables as predictors. The associations were assessed by Odds Ratio (OR), with a p-value work-related accidents were (a) attending formal education for an above average number of years (OR=0.91, pwork-related accidents. This indicates the need, during the formulation of policies for these kinds of government benefits, to include nutrition aspects in order to minimize work-related accidents risks.

    Limited or delayed availability of parenteral nutrition (PN) solutions, as well as difficulties in ordering are often identified as reasons for non-compliance with international guidelines in newborns. This study aims at assessing the modality of use and safety of premixed standardized PN solutions in a nationwide prospective cohort of newborns treated in clinical practice. Two premixed fixed formulations with respective osmolarity of 715 and 790 mOsm/L specifically designed for neonates were made available throughout the country for clinical use from birth onwards. Descriptive data and modality of use were prospectively collected in a case report form, whereas all related and unrelated adverse events were recorded on a separate adverse event form. A total of 14,167 infants were prospectively included and 16,640 parenteral nutrition periods were analyzed. Mean age was 33 weeks of gestation, and mean weight was 2086 g. The majority of infants (81%) started the parenteral nutrition the first day of life or the day after. The route of parenteral nutrition delivery was peripheral in 47% of the parenteral nutrition periods. During the whole study, a total of 72 adverse events occurring in 68 infants were reported. Of these adverse events, 59 (0.37% of the nutrition periods), among which 19 serious adverse events, were reported as related to the parenteral nutrition solutions. The events related to parenteral nutrition solutions were general disorders and administration site conditions (n = 42 including 9 cases of cutaneous necrosis), and nutrition and metabolism disorders (n = 17). There was no case of thrombophlebitis. Six of the 19 serious events related to the parenteral nutrition solutions (32%) were due to the misuse of the infusion bag. These data support the concept that ready-to-use parenteral nutrition formulations can safely provide parenteral nutrition from birth onwards. They further support that parenteral solutions with an osmolarity up to 800

    In this study the effects on nutritional status and energetic metabolism due the abdominal irradiation were analysed. Adult male wistar rats (48), were divided in two groups Control (C) and radiated (R). The rats were maintained all time in metabolic cages. the study was done in two periods: period 1 begun at 0 day, were rats adapted to cages and oral diet, had food and water ad libitum. At the day four indirect calorimetric measurements were performed (calorimetry 1). At period 2, group R rats abdominal radiation at a 300 c Gy/day rate, for 5 consecutive days, and group C started a pair-feeding process linked individually to R rats and suffered application to simulated-irradiation. Two other calorimetric measurements (II,III) were performing during period 2. After radiation the last calorimetry was performed (IV). At sacrifice (day 14) blood was collected for determination of hemoglobin, hematocrit, albumin and transferrin. There were no statistical differences among groups C and R during period 1 (p < 0.05). Great reduction in food intake and weight variation were found in period 2, but weight loss was significantly higher in R rats. Nitrogen balance decrease in period 2, but without difference among the groups (p < 0.05). Serum albumin was significantly lower in R rats. Respiratory quotient decreased in both groups during period 2, but rats kept it lower (p < 0.05). The energy expenditure level decreased after radiation in group R. During period 2 total substrate oxidation decreased in R rats. Radiation decrease glucose and protein oxidation. In conclusion, in this study's conditions, radiation produced malnutrition by reducing food intake by bringing weight loss, hypoalbuminemia and decrease nitrogen balance. Radiation was also responsible for a reduction of metabolism, by promoting the fall of energy expenditure. These changes are not only due the anorexia, undoubtful a main factor. (author)

    Worldwide we are facing a serious demographic challenge due to the dramatic growth of the population over 60 years. It is expected that the proportion of this population will nearly double from 12 to 22 %, between 2015 and 2050. This demographic shift comes with major health and socio-economic concerns. Nutrition is a fundamental determinant of both health and disease and its role in extending a healthy lifespan is the object of considerable research. Notably, malnutrition is one of the main threats to health and quality of life among the elderly. Therefore, knowledge about nutritional status among the elderly is essential for the promotion and maintenance of healthy ageing and to support the development of health protection policies and equity in elderly health care. This is a nationwide nutrition survey of the Portuguese population over 65 years old, with data collection through face-to-face interviews. A representative and random sample of community dwelling elderly and nursing homes residents will be obtained by multistage sampling stratified per main Portuguese regions, sex and age groups. Minimum sample size was estimated to be 2077 elderly (979 in the community and 1098 in nursing homes). Data will be collected on food habits and eating patterns, nutritional status, food insecurity, lifestyle, self-rated general health status and self-reported diseases, functionality, loneliness, cognitive function, emotional status and demographic and socio-economic characterization. This is the first national survey to evaluate the prevalence of nutritional risk and malnutrition of the Portuguese population above 65 years old, including those living in nursing homes. It will allow the identification of population subgroups of elderly with increased odds of malnutrition and nutritional risk. In addition, this survey will contribute to the identification of psychosocial and clinical predictors of malnutrition among elderly, which is an important risk factor for other

    Bone mass is influenced by genetic and environmental factors. Recent studies have highlighted associations between maternal nutritional status during pregnancy and bone mass in the offspring. We hypothesized that maternal calcium intakes and circulating micronutrients during pregnancy are related to bone mass in Indian children. DESIGN/SETTING/PARTICIPANTS/MAIN OUTCOME MEASURES: Nutritional status was measured at 18 and 28 wk gestation in 797 pregnant rural Indian women. Measurements included anthropometry, dietary intakes (24-h recall and food frequency questionnaire), physical workload (questionnaire), and circulating micronutrients (red cell folate and plasma ferritin, vitamin B12, and vitamin C). Six years postnatally, total body and total spine bone mineral content and bone mineral density (BMD) were measured using dual-energy x-ray absorptiometry (DXA) in the children (n = 698 of 762 live births) and both parents. Both parents' DXA measurements were positively correlated with the equivalent measurements in the children (P pregnancy (milk, milk products, pulses, non-vegetarian foods, green leafy vegetables, fruit) had higher total and spine bone mineral content and BMD, and children of mothers with higher folate status at 28 wk gestation had higher total and spine BMD, independent of parental size and DXA measurements. Modifiable maternal nutritional factors may influence bone health in the offspring. Fathers play a role in determining their child's bone mass, possibly through genetic mechanisms or through shared environment.

    Full Text Available Maternal mortality in childbirth in developing countries is still high. The study describes the qualitative methods used to examine the knowledge, attitude, beliefs and behaviour related to nutrition and nutritional supplementation of pregnant women. The role of village midwives and cadres’ in relation to nutrition education resulted in improving nutritional behaviour of pregnant women to some extent, but poverty and culture restricted the ability of pregnant women to access better food. The study shows that the position of pregnant woman is low within the hierarchy of both the health care system and the power structures of the broader community. Husbands, mothers-in-law, village midwives, cadres and village leaders all have more power in determining nutrition during pregnancy. However, some women tried to eat better and more nutritious food in secret, thereby subverting culture and the authority of husbands and mothers-in-law.

    Interest in vegetarian diets is growing in Italy and elsewhere, as government agencies and health/nutrition organizations are emphasizing that regular consumption of plant foods may provide health benefits and help prevent certain diseases. We conducted a Pubmed search, up to September, 2015, for studies on key nutrients (proteins, vitamin B12, iron, zinc, calcium, vitamin D, and n-3 fatty acids) in vegetarian diets. From 295 eligible publications the following emerged: Vegetarians should be encouraged to supplement their diets with a reliable source of vitamin B12 (vitamin-fortified foods or supplements). Since the plant protein digestibility is lower than that of animal proteins it may be appropriate for vegetarians to consume more proteins than recommended for the general population. Vegetarians should also be encouraged to habitually consume good sources of calcium, iron and zinc - particularly vegetables that are low in oxalate and phytate (e.g. Brassicaceae), nuts and seeds, and calcium-rich mineral water. Calcium, iron, and zinc bioavailability can be improved by soaking, germination, and sour-dough leavening that lower the phytate content of pulses and cereals. Vegetarians can ensure good n-3 fatty acid status by habitually consuming good sources of a-linolenic acid (walnuts, flaxseeds, chia seeds, and their oils) and limiting linoleic acid intake (corn and sunflower oils). Well-planned vegetarian diets that include a wide variety of plant foods, and a reliable source of vitamin B12, provide adequate nutrient intake. Government agencies and health/nutrition organizations should provide more educational resources to help Italians consume nutritionally adequate vegetarian diets. Copyright © 2017.

  20. Getting the Dimensions Right - Human Nutrition as Key for the Control of Regional Nitrogen Fluxes

    2009-04-01

    The western society is rested upon a strong animal-based (meat, eggs, milk) nutrition, which is far of a healthy balanced diet. Furthermore, the production of animal based food consumes five to six times more resources (e.g.: area, fertilizer) compared to plant-based food and is closely connected to environmental pollution (e.g.: emission of greenhouse gases, water pollution). Especially the regional nitrogen turnover is highly driven by the request from human nutrition on agricultural production. While the efficiency of the transfer of applied nitrogen into the product is 60 - 70 % for vegetarian food, it is 15 - 25 % for animal based food. This contribution is going to demonstrate the most important nitrogen fluxes on national scale in Austria calculated using a national material flow analysis. The national nitrogen balance is driven by the production of nitrogen fertiliser and import of fooder. The airborne transport of reactive nitrogen (NOX and NHX) plays a decisive role within this balance. The main losses into the environment occur during the agricultural production process. Losses to the atmosphere exceed losses to groundwater and surface waters. After introduction of nitrogen removal at treatment plants, emissions to surface waters are dominated by land use driven fluxes via groundwater. The influence of nitrogen depositions on land (agricultural area, forest and mountain regions) on nitrogen emissions to the water system is in the same order of magnitude as the direct emissions due to fertiliser application - especially in a country as Austria with high shares of mountainous and silvicultural areas. Sources for depositions of reactive nitrogen are mainly NH3 emissions to the air from animal husbandry and NOX emissions to the air from traffic. Both substance are matter of transboundary transport and thus are highly influenced by activities outside a specific country or river catchment. Management of nitrogen on a national or catchment scale has therefore

    The link between dietary fats and cardiovascular disease has created a growing interest in dietary red palm oil research. Also, the link between nutrition and health, oxidative stress and the severity or progression of disease has stimulated further interest in the potential role of red palm oil (a natural antioxidant product) to improve oxidative status by reducing oxidative stress in patients with cardiovascular disease, cancer and other chronic diseases. In spite of its level of saturated fatty acid content (50%), red palm oil has not been found to promote atherosclerosis and/or arterial thrombosis. This is probably due to the ratio of its saturated fatty acid to unsaturated fatty acid content and its high concentration of antioxidants such as beta-carotene, tocotrienols, tocopherols and vitamin E. It has also been reported that the consumption of red palm oil reduces the level of endogenous cholesterol, and this seems to be due to the presence of the tocotrienols and the peculiar isomeric position of its fatty acids. The benefits of red palm oil to health include a reduction in the risk of arterial thrombosis and/or atherosclerosis, inhibition of endogenous cholesterol biosynthesis, platelet aggregation, a reduction in oxidative stress and a reduction in blood pressure. It has also been shown that dietary red palm oil, taken in moderation in animals and humans, promotes the efficient utilisation of nutrients, activates hepatic drug metabolising enzymes, facilitates the haemoglobinisation of red blood cells and improves immune function. This review provides a comprehensive overview of the nutritional, physiological and biochemical roles of red palm oil in improving wellbeing and quality of life.

    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 provision of nutrition care by doctors is important in promoting healthy dietary habits, and such interventions can lead to reductions in disease morbidity, mortality, and medical costs. However, medical students and doctors report inadequate nutrition education and preparedness during their training at school. Previous studies investigating the inadequacy of nutrition education have not sufficiently evaluated the perspectives of students. In this study, students' perspectives on doctors' role in nutrition care, perceived barriers, and strategies to improve nutrition educational experiences are explored. A total of 23 undergraduate clinical level medical students at the 5th to final year in the School of Medicine and Health Sciences of the University for Development Studies in Ghana were purposefully selected to participate in semi-structured individual interviews. Students expressed their opinions and experiences regarding the inadequacy of nutrition education in the curriculum. Each interview was audio-recorded and later transcribed verbatim. Using the constant comparison method, key themes were identified from the data and analysis was done simultaneously with data collection. Students opined that doctors have an important role to play in providing nutrition care to their patients. However, they felt their nutrition education was inadequate due to lack of priority for nutrition education, lack of faculty to provide nutrition education, poor application of nutrition science to clinical practice and poor collaboration with nutrition professionals. Students opined that their nutrition educational experiences will be improved if the following strategies were implemented: adoption of innovative teaching and learning strategies, early and comprehensive incorporation of nutrition as a theme throughout the curriculum, increasing awareness on the importance of nutrition education, reviewing and revision of the curriculum to incorporate nutrition, and involving

    Disease-related malnutrition is a common comorbidity at hospital admission. The purpose of the present report was to describe the data on nutritional care routines collected during the Project: Iatrogenic MAlnutrition in Italy (PIMAI) study, as these may be helpful to avoid iatrogenic malnutrition and improve nutritional policies. Standards of nutritional care were assessed on the basis of (1) adherence to study protocol (completeness of data collected); (2) attitude in assessing the nutritional status; (3) prescription of nutritional therapy (within 3 days) at least in patients presenting with overt malnutrition (body mass index (BMI) or=10% in 3 months and/or >or=5% in the last month)), regardless of its adequacy, and adherence to current guidelines and (4) attitude in monitoring nutritional status during the stay (number of weight measurements performed compared with those expected). In total, 1583 subjects were assessed. A minimum data set for performing the Nutritional Risk Screening 2002 tool was available in 1284 patients (81.1%), but nutritional screening was possible in every patient by alternative analytical criteria related to food intake, anthropometry and biochemistry. However, several missing values were recorded, particularly in biochemical parameters due to lack of prescription by admission wards. According to ward practices, only 38.2% of the patients had the BMI calculated. A nutritional support was prescribed only to 26/191 patients (13.6%) presenting with overt malnutrition. Finally, we recorded that only 21.6% of the patients (207/960 were randomly selected) had their weight monitored on a scheduled basis. This reality was worse in surgical rather than medical departments (17 vs 26%; P<0.001). Present results confirm that in Italy, nutritional care routines are still poor and need improvements.

  7. A socioecological analysis of the determinants of national public health nutrition work force capacity: Australia as a case study.

    This article uses a socioecological analytical approach to assess the capacity of the public health nutrition work force in Australia as a prelude to work force development strategy planning. It demonstrates how the socioecological model can be used to assess and inform the development of the infrastructure required for effective public health nutrition effort. An interpretive case study method was used involving triangular analysis of quantitative and qualitative data from multiple sources including semistructured interviews with advanced-level practitioners, literature review, a cross-sectional national work force survey, and position description audit and consensus development using a Delphi study. The findings of this analysis indicate that the Australian public health nutrition work force's capacity to effectively address priority nutrition issues is limited by determinants that can be categorized as relating to human resource infrastructure, organizational and policy environments, intelligence access and use, practice improvement and learning systems, and work force preparation. This socioecological analysis supports an intelligence-based focus for work force development effort in Australia and a conceptual framework for work force capacity assessment with potential applications in other countries.

    Full Text Available Background: The role of micronutrient status for the incidence and clinical course of cutaneous leishmaniasis is not much studied. Still zinc supplementation in leishmaniasis has shown some effect on the clinical recovery, but the evidence in humans is limited. Objective: To compare biochemical nutritional status in cutaneous leishmaniasis patients with that in controls and to study the effects of zinc supplementation for 60 days. Design: Twenty-nine patients with cutaneous leishmaniasis were treated with antimony for 20 days. Fourteen of them got 45 mg zinc daily and 15 of them got placebo. Biomarkers of nutritional and inflammatory status and changes in size and characteristics of skin lesions were measured. Results: The level of transferrin receptor was higher in patients than in controls but otherwise no differences in nutritional status were found between patients and controls. No significant effects of zinc supplementation on the clinical recovery were observed as assessed by lesion area reduction and characteristics or on biochemical parameters. Conclusions: It is concluded that nutritional status was essentially unaffected in cutaneous leishmaniasis and that oral zinc supplementation administered together with intramuscular injection of antimony had no additional clinical benefit.

    The majority of cancer patients becomes malnourished during the course of their disease. Malnutrition deteriorates the efficiency of all kinds of oncologic interventions. As a consequence of it, treatment-related toxicity increases, hospital stay is lengthened, chances of cure and survival as well as the quality of life of the patients worsen. Nutritional status therefore influences all aspects of outcome of oncology care. In spite of this the use of nutritional therapy varies across health care providers but its application is far from being sufficient during active oncology interventions as well as rehabilitation and supportive care. It threatens not only the outcome and quality of life of cancer patients but also the success of oncologic treatments which often demand high input of human and financial resources. Meanwhile application of nutritional therapy is legally regulated in Hungary and a very recent update of the European guideline on cancer patient nutrition published in 2017 is available. Moreover, cost effectiveness of nutritional therapy has been proven in a number of studies. In this review we present the basics of nutritional therapy including nutritional screening and evaluation, nutritional plan, the role of nutrition support teams, oral, enteral and parenteral nutrition, the use of different drugs and special nutrients and the follow-up of the patients.

    Full Text Available Nearly half of the world population suffers from micronutrient malnutrition, particularly Zn deficiency. It is important to understand genetic variation for uptake and translocation behaviors of Zn in relevant crop species to increase Zn concentration in edible parts. In the present study, genetic variation in grain Zn concentration of 319 finger millet genotypes was assessed. Large genetic variation was found among the genotypes, with concentrations ranging from 10 to 86 μg g− 1 grain. Uptake and translocation studies with Zn/65Zn application in 12 selected low-Zn genotypes showed wide variation in root uptake and shoot translocation, with genotypes GEC331 and GEC164 showing greater uptake and translocation. Genotypes GEC164 and GEC543 showed increased grain Zn concentration. Genotypes GEC331 and GEC164 also showed improved yield under Zn treatment. Appreciable variation in grain Zn concentration among finger millet genotypes found in this study offers opportunities to improve Zn nutrition through breeding.

    A high catabolic rate characterizes the acute phase of critical illness. Guidelines recommend an early nutritional support, regardless of the previous nutritional status. We aimed to assess whether the nutritional status of patients, which was defined by the body mass index (BMI) at admission in an intensive care unit (ICU), affected the time of nutritional support initiation. We conducted a cohort study that reported a retrospective analysis of a multicenter ICU database (OUTCOMEREA) by using data prospectively entered from January 1997 to October 2012. Patients who needed orotracheal intubation within the first 72 h and >3 d were included. Data from 3257 ICU stays were analyzed. The delay before feeding was different according to BMI groups (P = 0.035). The delay was longer in obese patients [BMI (in kg/m²) ≥30; n = 663] than in other patients with either low weight (BMI nutritional status and a delay in nutrition initiation was independent of potential confounding factors such as age, sex, and diabetes or other chronic diseases. In comparison with normal weight, the adjusted RR (95% CI) associated with a delayed nutrition initiation was 0.92 (0.86, 0.98) for patients with low weight, 1.00 (0.94, 1.05) for overweight patients, and 1.06 (1.00, 1.12) for obese patients (P = 0.004). The initiation of nutritional support was delayed in obese ICU patients. Randomized controlled trials that address consequences of early compared with delayed beginnings of nutritional support in critically ill obese patients are needed. © 2014 American Society for Nutrition.

    Mountain marathons are 2-d, self-supported adventure races, during which competitors must carry all nutritional requirements to sustain athletic effort. This requires a compromise between the energy required to perform and the weight penalty of carrying it. We have undertaken a nutritional survey of event competitors in the UK using a questionnaire-based approach and have monitored dehydration during the event. We found that competitors in longer-distance classes (> 50 km) carry significantly less mass of food, which is more energy dense, but that the calorific value is lower than that of competitors in shorter classes. Carbohydrate and protein consumption both positively associated with performance. Competitors became progressively dehydrated throughout the event. Counterintuitively, the better-performing subjects became the most dehydrated. Competitors at all distances should make more effort to rehydrate during breaks in the event. Competitors at shorter distances could choose more energy-dense foods to reduce weight penalty.

    Malnutrition is a predictor of poor outcomes in patients with cancer. Little is known about the benefit of nutritional support in these patients. The purpose of this study was to assess the impact of home parenteral nutrition (HPN) on quality of life (Qol) in cancer patients. We performed an observational prospective study to determine the impact of HPN on Qol in a population of patients with heterogeneous cancer. Physicians, patients and family members had to complete a questionnaire before HPN administration and 28 days after the course of HPN. Qol was evaluated using the self-administered questionnaire FACT-G. We included 767 patients with cancer of whom 437 ended the study. Mean patient age was 63±11.4 years and 60.5% were men. Primary gastrointestinal cancer was reported in 50% of patients and 65.3% were presenting metastases. Malnutrition was reported in 98.3%. After 28 days of HPN intake, significant improvement was observed in the Qol (49.95±5.82 vs. 48.35±5.01 at baseline, pnutrition risk index had also improved significantly. Most patients (78%) had perceived a positive impact of the HPN. A significant improvement in patient's well-being was perceived also by family members and physicians. Our data suggest that preventing and correcting malnutrition using HPN in patients with cancer might have a significant benefit on their well-being. Randomized controlled studies are required to confirm this finding.

    Full Text Available Growth and biochemical content of medicinal crops are influenced by agroecosystems characteristics . The objective of this research was to determine the optimum shading level and type of fertilizer as sources of nutrition on the growth, yield, and andrographolide content of sambiloto. The experiment used Split Plot Design with basic design of Randomized Complete Block Design arranged with two treatment factors, with three replications. The first factor as the main plot was shading levels, namely without shading, 25% shading, 50% shading, and 75% shading. The second factor as the sub plot was sources of nutrition reprented by type of fertilizer, namely NPK fertilizer, cow stable fertilizer, and compost fertilizer. The result of research indicated that shading level and the kind of nutrition influenced some growth and yield variables such as number of leaves, number of branches, plant height, plant dry weight and simplisia weight, and andrographolide content. Interaction of shading level at 25% and straw compost fertilizer performed best in growth characteristics, while the highest andrographolide content resulted from the treatment combination of 50% shading level and straw compost fertilizer.

    To compare and contrast current nutritional rehabilitation practices against recommendations from National Institute for Health and Excellence guideline Rehabilitation after critical illness (NICE) (2009, http://www.nice.org.uk/cg83). Recovery from critical illness has gained increasing prominence over the last decade but there is remarkably little research relating to nutritional rehabilitation. The study is a qualitative study based on patient interviews and observations of ward practice. Seventeen patients were recruited into the study at discharge from the intensive care unit (ICU) of a large teaching hospital in central Scotland in 2011. Semi-structured interviews were conducted on transfer to the ward and weekly thereafter. Fourteen of these patients were followed up at three months post-ICU discharge, and a semi-structured interview was carried out. Observations of ward practice were carried out twice weekly for the duration of the ward stay. Current nutritional practice for post-intensive care patients did not reflect the recommendations from the NICE guideline. A number of organisational issues were identified as influencing nutritional care. These issues were categorised as ward culture, service-centred delivery of care and disjointed discharge planning. Their influence on nutritional care was compounded by the complex problems associated with critical illness. The NICE guideline provides few nutrition-specific recommendations for rehabilitation; however, current practice does not reflect the nutritional recommendations that are detailed in the rehabilitation care pathway. Nutritional care of post-ICU patients is problematic and strategies to overcome these issues need to be addressed in order to improve nutritional intake. © 2013 John Wiley & Sons Ltd.

    To test the novel hypothesis that nutritional factors previously associated with type 1 diabetes etiology or with insulin secretion are prospectively associated with fasting C-peptide (FCP) concentration among youth recently diagnosed with type 1 diabetes. Included were 1,316 youth with autoantibody-positive type 1 diabetes who participated in the SEARCH for Diabetes in Youth study (baseline disease duration, 9.9 months; SD, 6.3). Nutritional exposures included breastfeeding and age at introduction of complementary foods, baseline plasma long-chain omega-3 fatty acids including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), vitamin D, vitamin E, and, from a baseline food frequency questionnaire, estimated intake of the branched-chain amino acid leucine and total carbohydrate. Multiple linear regression models were conducted to relate each nutritional factor to baseline FCP adjusted for demographics, disease-related factors, and other confounders. Prospective analyses included the subset of participants with preserved β-cell function at baseline (baseline FCP ≥0.23 ng/mL) with additional adjustment for baseline FCP and time (mean follow-up, 24.3 months; SD, 8.2; n = 656). FCP concentration was analyzed as log(FCP). In adjusted prospective analyses, baseline EPA (P = 0.02), EPA plus DHA (P = 0.03), and leucine (P = 0.03) were each associated positively and significantly with FCP at follow-up. Vitamin D was unexpectedly inversely associated with FCP (P = 0.002). Increased intake of branched-chain amino acids and long-chain omega-3 fatty acids may support preservation of β-cell function. This represents a new direction for research to improve prognosis for type 1 diabetes.

    Undernutrition and insufficient energy and protein intake is a common problem in hospitalised patients. The aim of this pilot study was to investigate whether a novel hospital menu would be an effective strategy for increasing nutritional intake in patients at nutritional risk. A historically controlled intervention pilot study was conducted. Forty patients at nutritional risk were offered a novel hospital menu as a supplement to the ordinary hospital menu. The menu consisted of 36 naturally energy-enriched small dishes served on demand 24 h a day. Energy and protein intake were calculated as the mean over a period of 3 days. No significant difference in energy and protein intake was observed between the groups; however, a significant (P = 0.001) time gradient in total energy intake was observed in the intervention group. Moreover, a significant (P = 0.03) time gradient in energy intake received from the novel menu was observed. The dishes from the novel menu were mainly ordered from 11.00 h to 14.00 h and from 17.00 h to 18.00 h. No overall significant differences in energy and protein intake between the groups were found. However, the present pilot study revealed a significant time gradient in total energy intake (P = 0.001) and in energy intake from the novel menu (P = 0.03). This indicates the need to include a run-in period when investigating novel hospital menus as a support for patients at nutritional risk. Additionally, food service, available 24 h a day, appears to be unnecessary. © 2012 The Authors Journal of Human Nutrition and Dietetics © 2012 The British Dietetic Association Ltd.

    In this observational study, we determined how frequently consumers accessed on-premises nutrition information provided at chain restaurants. The number of patrons entering and accessing nutrition information was recorded at 8 locations that were part of 4 major restaurant chains (McDonald's, Burger King, Starbucks, and Au Bon Pain). Only 6 (0.1%) of 4311 patrons accessed on-premises nutrition information before purchasing food. This very small percentage suggests that such information should be more prominently displayed, such as on restaurant menu boards, to help customers make informed decisions.

    Full Text Available The search for equity in access to services is presently an important principle in public policies for health in Brazil. Social inequalities in the Amazonia occur at high levels comparatively to the other regions in the country; and, within Amazonia, they particularly affect rural communities. The present study aims to appreciate associations between food and nutritional profile, adaptive strategies, and epidemiology in these communities, specially in areas of artisanal fishery, and also to suggest general lines of appropriated health policies. The construction of a context of equitable assistance and of sustainable health, without significant damage to biodiversity, depends on the capacity of public power in exploring the relationships between use and management of natural resources and the quality of life of riverine man.

    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. In the current study, we extend this work to explore the longitudinal associations of nutritional factors with Hb A1c in youth with T1D. 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. 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 1). 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. Several nutritional factors may be associated with Hb A1c during early stages of disease progression in youth recently diagnosed with T1D. In addition to the overall role of major macronutrients such as carbohydrates and

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.

    Full Text Available Nutritional status in patients on hemodialysis is always of concern as malnutrition predisposes to excess morbidity and mortality. Most of the nutritional supplements available in the market are expensive. We explored the possibility of improving nutrition of the patients on maintenance hemodialysis by supplementation of calories and proteins that can be given in the form of a palatable and economical gruel in this prospectively designed, open labeled study. Patients who were on maintenance hemodialysis (twice a week for a period of at least 6 months were divided into two groups. The study group was given the gruel supplement and the control group was not given the gruel supplement. Nutritional status was assessed in the study group and controls at 0 and 3 months by the following parameters: percentage body fat, mid arm muscle circumference and serum albumin. Analysis of results revealed that there was a significant decline in the protein intake at the end of the 3 rd month in the control group (P = 0.01. Other parameters did not show significant change at the end of the study period in both groups. The nutritional supplement can be assumed to have helped at least in the maintenance of protein intake over this short period and could possibly in the long run contribute to improvement of nutritional parameters.

    The prevention of essential fatty acid deficiency and the provision of adequate amounts of energy are two major concerns in total parenteral nutrition. Since earlier preparations of fat emulsion used to supplement the usual regimen of hypertonic glucose and amino acids have widely varying clinical acceptability, a new product, a safflower oil emulsion available in two concentrations (Liposyn), was evaluated. In four clinical trials the emulsion was used as a supplement to total parenteral nutrition. In five surgical patients 500 ml of the 10% emulsion infused every third day prevented or corrected essential fatty acid deficiency; however, in some cases in infusion every other day may be necessary. In 40 patients in severe catabolic states the emulsion provided 30% to 50% of the energy required daily: 10 patients received the 10% emulsion for 14 to 42 days, 9 patients received each emulsion in turn for 7 days, and 21 patient received the 20% emulsion for 14 to 28 days. All the patients survived and tolerated the lipid well; no adverse clinical effects were attributable to the lipid infusions. Transient mild, apparently clinically insignificant abnormalities in the results of one or more liver function tests and eosinophilia were observed in some patients. Thus, the safflower oil emulsion, at both concentrations, was safe and effective as a source of 30% to 50% of the energy required daily by seriously ill patients. PMID:6799182

    The measurement of individual food consumption rates of fish held in groups using radiography has enabled the development of a new approach to fish nutrition trials. In order to compare diets, groups of individually numbered fish are fed different experimental diets over extended periods of time (similar to standard nutrition trials) and food consumption rates are measured regularly over the course of the experiment. Analysis of covariance is then used to compare regression coefficients, obtained from mean consumption-growth relationships, from each diet. The advantages of the approach are several: (1) differences in appetite between fish fed different diets are monitored; (2) fewer fish are needed to establish consumption-growth curves over a large range of consumption rates; (3) measured food consumption rates, not ration levels, are used to calculate ‘true’ growth efficiencies; and (4) other factors, such as absorption efficiency, trypsin activity, the concentration of free amino acids in tissues and protein turnover can be measured for individual fish and related to differences in food consumption between fish in the same group. The approach has been used successfully with a variety of species to compare the growth response of groups fed two or more diets

    Nutritional rickets is usually attributed to vitamin D deficiency. Studies from some tropical countries have postulated low dietary intake of calcium as the cause of nutritional rickets. Both vitamin D and dietary calcium deficiency are highly prevalent in India. Information on their relative contribution in the development of rickets in Indian children is limited. The aim was to study the role of calcium and vitamin D deficiency in causation of nutritional rickets in young Indian children. In a case-control study, 67 children with nutritional rickets and 68 age- and sex-matched healthy controls were compared for demographic factors, nutritional status, sun exposure (UV score), dietary calcium and phytate intake (for subjects not breast-fed at presentation), and biochemical parameters [serum calcium, inorganic phosphate, alkaline phosphatase, 25-hydroxyvitamin D (25OHD), and PTH]. Mean intake of calcium (204±129 vs. 453±234 mg/d; Prickets, significant negative correlations were seen between dietary calcium intake and radiological score (r=-0.28; P=0.03) and PTH (r=-0.26; P=0.02). No correlation was found between serum 25OHD level and radiological score or biochemical parameters of rickets. Rickets develops when low dietary calcium intake coexists with a low or borderline vitamin D nutrition status.

With indirect calorimetry, resting energy expenditure (REE) of 92 burn adult patients were measured and analyzed, and on the basis of which a new formula for calculating nutritional supplement in Chinese burn adults was proposed: kcal/day = 1,000 x M2 (body surface area) + 25 x % TBSA (total burn surface area). 3. Through experimental and clinical studies, it was found that antiouperoxide agents (such as SOD, CAT), tolbutamide, glutamine and Chinese herb decoction Sizunzituang all exhibited modulating effects on postburn metabolism and nutrition, e.g. decreasing catabolism, reducing negative nitrogen balance, stimulating secretion of insulin, enhancing tissue utilization of glucose, maintaining the mass of enteral mucosa and improving functions of viscerae. 4. A new less irritating, simple and easy-to-introduce nasal-enteral nutrition tube was devised, which could pass through the pylorus easily into the duodenum usually within 6hrs without using a stylet. It would be useful in the early postburn enteral nutrition supplementation.

    The aims of this study were to explore (a) patients' perceptions of the role of nutrition in pressure ulcer prevention; and (b) patients' experiences with dieticians in the hospital setting. Interpretive qualitative study. The sample comprised 13 females and 7 males. Their mean age was 61.3 ± 12.6 years (mean ± SD), and their average hospital length of stay was 7.4 ± 13.0 days. The research setting was a public health hospital in Australia. In this interpretive study, adult medical patients at risk of pressure ulcers due to restricted mobility participated in a 20 to 30 minute interview using a semi-structured interview guide. Interview questions were grouped into 2 domains; perceptions on the role of nutrition for pressure ulcer prevention; and experiences with dieticians. Recorded interviews were transcribed and analyzed using content analysis. Within the first domain, 'patient knowledge of nutrition in pressure ulcer prevention,' there were varying patient understandings of the role of nutrition for prevention of pressure ulcers. This is reflected in 5 themes: (1) recognizing the role of diet in pressure ulcer prevention; (2) promoting skin health with good nutrition; (3) understanding the relationship between nutrition and health; (4) lacking insight into the role of nutrition in pressure ulcer prevention; and (5) acknowledging other risk factors for pressure ulcers. Within the second domain, patients described their experiences with and perceptions on dieticians. Two themes emerged, which expressed differing opinions around the role and reputation of dieticians; they were receptive of dietician input; and displaying ambivalence towards dieticians' advice. Hospital patients at risk for pressure ulcer development have variable knowledge of the preventive role of nutrition. Patients had differing perceptions of the importance and value of information provided by dieticians.

    Full Text Available Identification, propagation, and introduction of a nutritionally rich, indigenous plant species in the existing cropping system are presented in this paper as a method of rural nutrition intervention. A case study of Moringa (Moringa oleifera Lam., Moringaceae, which is a common tree in Malawi and one of the richest sources of vitamin A and vitamin C compared to the commonly consumed vegetables is presented to address the problem of vitamin A deficiency. After a brief review of the prevalence of vitamin A deficiency and the efforts to reduce its incidence in Malawi, Moringa is suggested as a potential solution to the problem. A framework for designing nutrition intervention with Moringa is described for actual implementation. It is argued that attempts to identify, document, and encourage the utilization of nutrient-rich indigenous plants could be cost-effective, and a sustainable method of improving the nutritional status of local populations.

    The aim of this study was to assess and analyze the nutritional status of gastric cancer (GC) patients. The analysis included 207 patients with GC treated in a large center of oncology. Patients were divided into two groups according to the cutoff value of the mean prognostic nutritional index (PNI): those with a PNI 10% (P = 0.000031). Body mass index (BMI) after disease recognition, albumin and total protein (0.003) levels, total lymphocyte count, and PNI were significantly lower in patients with nutritional risk. Significantly lower BMI before disease and BMI after disease recognition were noted in smoking patients. Significantly higher total lymphocyte count was observed in smoking patients (P nutritional status using PNI calculation should be the standard management of patients with GC before treatment.

    The aim of this study was to report a multifaceted knowledge translation intervention to facilitate use of the Malnutrition Universal Screening Tool and innovation in nutritional care for patients at risk of malnutrition. Malnutrition among hospitalized patients is a widespread problem leading to adverse health outcomes. Despite evidence of the benefits of malnutrition screening and recommendations for achieving good nutrition, shortfalls in practice continue. A mixed method integrated knowledge translation study. The knowledge translation intervention comprised nutrition champions supported by knowledge translation facilitators and an action planning process. Data collection was undertaken over 18 months between 2011-2012 in a hospital in England. Data comprised observation of mealtimes, audit of patient records, survey of nurses and semi-structured interviews with nutrition champions, knowledge translation facilitators, senior ward nurses and nurse managers. Statistically significant relationships (Chi Square) were observed between self-reported confidence of nurses (a) to assess patients using the Malnutrition Universal Screening Tool, (b) to teach colleagues how to use the Malnutrition Universal Screening Tool and (c) to ensure that patients were assessed within 24 hours of admission. Ward-based nutrition champions facilitated successful innovation in nutrition support. Contextual factors operating at micro (ward), meso (organization) and macro (healthcare system) levels acted as barriers and enablers for change. Nutrition champions were successful in increasing the timely assessment of patients at risk of malnutrition and promoting innovation in nutritional care. Support from knowledge translation facilitators helped nutrition champions develop their role and work collaboratively with senior ward nurses to implement action plans for improving nutrition. © 2016 John Wiley & Sons Ltd.

    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. 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. 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 (Ppregnancy, language, and having a health/nutrition qualification. The model indicated that independent variables explained 33% (adjusted R (2)) of the variance found between respondents' knowledge scores. 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 improvement in their nutrition knowledge. It is essential that women receive support to achieve optimal and

    Background: In nutritional studies, pigs are often used as models for humans because of nutritional and physiologic similarities. However, evidence supporting similar metabolic responses to nutritional interventions is lacking. Objective: The objective was to establish whether pigs and humans...... respond similarly to a nutritional intervention. Using metabolomics, we compared the acute metabolic response to 4 test breads between conventional pigs (growing) and adult human subjects (with the metabolic syndrome). Design: Six catheterized pigs and 15 human subjects were tested in a randomized...... different basal metabolome concentrations in the plasma of pigs and humans. Humans had higher contents of phosphatidylcholines, oleic acid, and carnitine in plasma, possibly reflecting a higher intake of meats and fats. In pigs, betaine, choline, creatinine, tryptophan, and phenylalanine were higher...

  13. Fat content, energy value and fatty acid profile of donkey milk during lactation and implications for human nutrition

    Full Text Available Abstract Background and aims Milk contains numerous nutrients. The content of n-3 fatty acids, the n-6/n-3 ratio, and short- and medium-chain fatty acids may promote positive health effects. In Western societies, cow’s milk fat is perceived as a risk factor for health because it is a source of a high fraction of saturated fatty acids. Recently, there has been increasing interest in donkey’s milk. In this work, the fat and energetic value and acidic composition of donkey’s milk, with reference to human nutrition, and their variations during lactation, were investigated. We also discuss the implications of the acidic profile of donkey’s milk on human nutrition. Methods Individual milk samples from lactating jennies were collected 15, 30, 45, 60, 90, 120, 150, 180 and 210days after foaling, for the analysis of fat, proteins and lactose, which was achieved using an infrared milk analyser, and fatty acids composition by gas chromatography. Results The donkey’s milk was characterised by low fat and energetic (1719.2kJ·kg-1 values, a high polyunsaturated fatty acids (PUFA content of mainly α-linolenic acid (ALA and linoleic acid (LA, a low n-6 to n-3 FA ratio or LA/ALA ratio, and advantageous values of atherogenic and thrombogenic indices. Among the minor PUFA, docosahesaenoic (DHA, eicosapentanoic (EPA, and arachidonic (AA acids were present in very small amounts ( The fatty acid patterns were affected by the lactation stage and showed a decrease (P Conclusions The high level of unsaturated/saturated fatty acids and PUFA-n3 content and the low n-6/n-3 ratio suggest the use of donkey’s milk as a functional food for human nutrition and its potential utilisation for infant nutrition as well as adult diets, particular for the elderly.

    This was a pilot study to determine the impact of the Michigan Model (MM) Nutrition Curriculum on nutrition knowledge, efficacy expectations, and eating behaviors in middle school students. The study was conducted in a large metropolitan setting and approved by the Institutional Review Board. The participants for this study were divided into an intervention group (n = 407) and a control group (n = 169). An MM instructor trained health teachers in the use of the curriculum, and the teacher subsequently taught the curriculum to students in the intervention group. A valid and reliable questionnaire was used to determine pre-post differences. It consisted of 3 subscales assessing eating habits, nutrition knowledge, and efficacy expectations toward healthy eating. Subscale scores were analyzed using a 2 groups (intervention vs control) x 2 times (pre vs post) analysis of variance. The intervention group increased their nutrition knowledge at post. There was also a significant main effect for groups in the subscales "Eating Behaviors" and "Efficacy Expectations Regarding Healthy Eating." Subsequent post hoc analysis revealed that the intervention group was significantly more likely to eat fruits and vegetables and less likely to eat junk food than the control group. Students in the intervention group also felt more confident that they could eat healthy. The results of this pilot study suggest that the MM Nutrition Curriculum delivered by trained professionals resulted in significant positive changes in both nutrition knowledge and behaviors in middle school children. Further research needs to be conducted to determine the long-term impact.

    To explore the association between oral health and nutritional status in the context of daily care for older people. Oral problems often increase with age and affect a person's ability to chew and swallow. They might also influence the ability to maintain a satisfactory nutritional status. Oral health awareness is therefore of great importance in nursing care for older people. A retrospective cross-sectional study. Data from the Swedish quality register, Senior Alert, were used, including structured assessments of both oral and nutritional status using the Revised Oral Assessment Guide-Jönköping and the Mini Nutritional Assessment. In total, 1,156 persons (mean age: 82.8 ± 7.9) had both oral and nutritional assessments registered by the nursing staff in daily care. Approximately 29% of participants had moderate oral health problems. Another 12% had severe problems. Over 60% of the persons were considered at risk of malnutrition or were malnourished. There was a weak correlation between poor nutritional status and poor oral health, and approximately one-third of the persons who were at risk or malnourished had simultaneous oral problems. A multivariate logistic regression revealed that when problems involving voice and swallowing were present, there was also a greater possibility of being assessed as at risk of malnourishment or being malnourished. There is a relationship between oral health problems and nutritional status, indicating the importance of evaluating oral health status in older persons with nutritional problems. Nursing staff involved in care for older people should be aware of the importance of including regular oral health check-ups in their work. There is also a need for nursing staff members and oral health professionals to exchange knowledge. © 2017 John Wiley & Sons Ltd.

This study describes the nutrition-care activities 30-days post-discharge reported by patients and what covariates are associated with these activities. Quasi-randomly selected patients recruited from 5 medical units across Canada (n = 513 consented to 30-days post-discharge data collection with 48.5% (n = 249 completing the telephone interview. Use of nutrition care post-discharge was reported and bivariate analysis completed with relevant covariates for the two most frequently reported activities, following recommendations post-discharge or use of oral nutritional supplements (ONS. A total of 42% (n = 110 received nutrition recommendations at hospital discharge, with 65% (n = 71/110 of these participants following those recommendations; 26.5% (n = 66 were taking ONS after hospitalization. Participants who followed recommendations were more likely to report following a special diet (p = 0.002, different from before their hospitalization (p = 0.008, compared to those who received recommendations, but reported not following them. Patients taking ONS were more likely to be at nutrition risk (p < 0.0001, malnourished (p = 0.0006, taking ONS in hospital (p = 0.01, had a lower HGS (p = 0.0013; males only, and less likely to believe they were eating enough to meet their body’s needs (p = 0.005. This analysis provides new insights on nutrition-care post-discharge.

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

    Science.gov (United States)

    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

    Malnutrition in critically ill adults in the intensive care unit (ICU) is associated with a significantly elevated risk of mortality. Adequate nutrition therapy is crucial to optimise outcomes. Currently, there is a paucity of such data in Latin America. Our aims were to characterise current clinical nutrition practices in the ICU setting in Latin America and evaluate whether current practices meet caloric and protein requirements in critically ill patients receiving nutrition therapy. We conducted a cross-sectional, retrospective, observational study in eight Latin American countries (Argentina, Brazil, Chile, Colombia, Ecuador, Mexico, Panama, and Peru). Eligible patients were critically ill adults hospitalised in the ICU and receiving enteral nutrition (EN) and/or parenteral nutrition (PN) on the Screening Day and the previous day (day -1). Caloric and protein balance on day -1, nutritional status, and prescribed nutrition therapy were recorded. Multivariable logistic regression analysis was performed to identify independent predictors of reaching daily caloric and protein targets. The analysis included 1053 patients from 116 hospitals. Evaluation of nutritional status showed that 74.1% of patients had suspected/moderate or severe malnutrition according to the Subjective Global Assessment. Prescribed nutrition therapy included EN alone (79.9%), PN alone (9.4%), and EN + PN (10.7%). Caloric intake met >90% of the daily target in 59.7% of patients on day -1; a caloric deficit was present in 40.3%, with a mean (±SD) daily caloric deficit of -688.8 ± 455.2 kcal. Multivariable logistic regression analysis showed that combined administration of EN + PN was associated with a statistically significant increase in the probability of meeting >90% of daily caloric and protein targets compared with EN alone (odds ratio, 1.56; 95% confidence interval, 1.02-2.39; p = 0.038). In the ICU setting in Latin America, malnutrition was highly prevalent and caloric

    Full Text Available Abstract Background Undenutrition is known to be prevalent and largely unrecognised in older patients; however, aberrations in indicators of nutritional status may simply reflect effects of age and/or functional disability. Objective The aim of this study was to measure the effect, if any of age on nutritional status in older patients. Design 445 randomly selected hospitalised patients consented to nutritional status assessment derived from anthropometric, haematological, and biochemical data within 72 hours of admission. Nutritional status was compared between those age Results Body weight, body mass index, mid-upper arm circumference, haemoglobin, serum albumin and plasma ascorbic acid were all significantly lower in people aged ≥ 75 years compared with those 3, red-cell folate and vitamin B12 concentrations were lower in those aged ≥ 75 years, differences were not statistically significant. After adjusting for disability and co-morbidity in a multivariate analysis, age alone had a significant and independent effect on important anthropometric and biochemical nutritional assessment variables. Conclusion Increasing age is independently associated with poor nutritional status. This may partly explain the poor clinical outcome in older patients.

    Human exometabolites inclusion into an intrasystem mass exchange will allow increasing of a closure level of a biological-technical life support system (BTLSS). Previously at the IBP SB RAS it was shown that human mineralized exometabolites could be incorporated in the BTLSS mass exchange as a mineral nutrition source for higher plants. However, it is not known how that combined use of human mineralized exometabolites and fish wastes in the capacity of nutrient medium, being a part of the BTLSS consumer wastes, will affect the plant productivity. Several wheat vegetations were grown in an uneven-aged conveyor on a neutral substrate. A mixture of human mineralized exometabolites and fish wastes was used as a nutrient solution in the experiment treatment and human mineralized exometabolites were used in the control. Consequently, a high wheat yield in the experiment treatment practically equal to the control yield was obtained. Thus, mineralized fish wastes can be an additional source of macro-and micronutrients for plants, and use of such wastes for the plant mineral nutrition allows increasing of BTLSS closure level.

    The SELEVER study is designed to evaluate the impact of an integrated agriculture-nutrition package of interventions (including poultry value chain development, women's empowerment activities, and a behavior change communications strategy to promote improved diets and feeding, care, and hygiene practices) on the diets, health, and nutritional status of women and children in Burkina Faso. This paper presents the rationale and study design. The impact evaluation involves a cluster randomized controlled trial design that will be implemented in 120 rural communities/villages within 60 communes supported by SELEVER in the Boucle de Mouhoun, Centre-Ouest, and Haut-Bassins regions of Burkina Faso. Communities will be randomly assigned to one of three treatment arms, including: (1) SELEVER intervention group; (2) SELEVER with an intensive WASH component; and (3) control group without intervention. Primary outcomes include the mean probability of adequacy of diets for women and children (aged 2-4 years at baseline), infant and young child feeding practices of caregivers of children aged 0-2 years, and household poultry production and sales. Intermediate outcomes along the agriculture and nutrition pathways will also be measured, including child nutrition status and development. The evaluation will follow a mixed-methods approach, including a panel of child-, household-, community-, and market-level surveys, and data collection points during post-harvest and lean seasons, as well as one year after implementation completion to examine sustainability. To our knowledge, this study is the first to rigorously examine from a food systems perspective, the simultaneous impact of scaling-up nutrition-specific and nutrition-sensitive interventions through a livestock value-chain and community-intervention platform, across nutrition, health, and agriculture domains. The findings of this evaluation will provide evidence to support the design of market-based nutrition

    Red-meat lipid peroxidation in the stomach results in postprandial oxidative stress (POS) which is characterized by the generation of a variety of reactive cytotoxic aldehydes including malondialdehyde (MDA). MDA is absorbed in the blood system reacts with cell proteins to form adducts resulting in advanced lipid peroxidation end products (ALEs), producing dysfunctional proteins and cellular responses. The pathological consequences of ALEs tissue damage include inflammation and increased risk for many chronic diseases that are associated with a Western-type diet. In earlier studies we used the simulated gastric fluid (SGF) condition to show that the in vitro generation of MDA from red meat closely resembles that in human blood after consumption the same amount of meat. In vivo and in vitro MDA generations were similarly suppressed by polyphenol-rich beverages (red wine and coffee) consumed with the meal. The present study uses the in vitro SGF to assess the capacity of more than 50 foods of plant origin to suppress red meat peroxidation and formation of MDA. The results were calculated as reducing POS index (rPOSI) which represents the capacity in percent of 100g of the food used to inhibit lipid peroxidation of 200g red-meat a POSI enhancer (ePOSI). The index permitted to extrapolate the need of rPOSI from a food alone or in ensemble such Greek salad, to neutralize an ePOSI in stomach medium, (ePOS-rPOSI=0). The correlation between the rPOSI and polyphenols in the tested foods was R 2 =0.75. The Index was validated by comparison of the predicted rPOSI for a portion of Greek salad or red-wine to real inhibition of POS enhancers. The POS Index permit to better balancing nutrition for human health. Copyright © 2017. Published by Elsevier B.V.

    Cancer disease is usually associated with impaired nutritional status, which is one of the factors contributing to deterioration of the results of surgery, chemotherapy or radiotherapy. The aim of the study was to determine whether nutritional support with high protein (ONS) in adult oncologic patients in the first step of cancer cachexia-asymptomatic precachexia, has an influence on the toxicity of systemic therapy. However, secondary endpoints were established: to determine whether high protein ONS influences the nutritional status, the quality of life, and the performance status. A total of 114 persons aged 40-84 years old with colorectal cancer were examined. Based on the randomization, 47 patients were qualified to the interventional group (ONS group) and 48 to Control group. To evaluate the nutritional status NRS-2002 (Nutritional Risk Screening), SGA (Subjective Global Assessment), SCRINIO (SCReenIng the Nutritional status In Oncology) Working Group classification, VAS (Visual Analog Scale) for appetite was used. FAACT (Functional Assessment of Anorexia/Cachexia Therapy) questionnaire was used for assessment of the quality of life.

    Full Text Available Due to higher energy consumption, physically active people have higher nutritional requirements. In addition to other important factors for sports, such as good health and physical predisposition, adequate nutrition is a fundamental component. Sports nutrition must be well planned and individually adapted based on physical characteristics, tendencies towards gaining or losing weight, frequency, duration and intensity of training sessions. Studies have shown that a well-balanced ratio of macro and micronutrients, with the support of supplements and adequate hydration, can significantly improve athletic performance and plays a key role in achieving better results. An optimally designed nutritional program, with realistic and achievable goals, which complements a well-planned training program, is the basis for success in sports. Only when nutritional requirements are met, deficits can be prevented and performance in sport pushed to the limit.

    National guidelines emphasize healthy eating to promote wellbeing and prevention of non-communicable diseases. The perceived healthiness of food is determined by many factors affecting food intake. A positive perception of healthy eating has been shown to be associated with greater diet quality. Internet-based methodologies allow contact with large populations. Our present study aims to design and evaluate a short nutritional perception questionnaire, to be used as a screening tool for assessing nutritional status, and to predict an optimal level of personalisation in nutritional advice delivered via the Internet. Data from all participants who were screened and then enrolled into the Food4Me proof-of-principle study (n = 2369) were used to determine the optimal items for inclusion in a novel screening tool, the Nutritional Perception Screening Questionnaire-9 (NPSQ9). Exploratory and confirmatory factor analyses were performed on anthropometric and biochemical data and on dietary indices acquired from participants who had completed the Food4Me dietary intervention (n = 1153). Baseline and intervention data were analysed using linear regression and linear mixed regression, respectively. A final model with 9 NPSQ items was validated against the dietary intervention data. NPSQ9 scores were inversely associated with BMI (β = -0.181, p nutritional status and to tailor nutritional advice. NCT01530139 .

    The aim of this study was evaluating if the presence of a humanoid robot could improve the efficacy of a game-based, nutritional education intervention. This was a controlled, school-based pilot intervention carried out on fourth-grade school children (8-10 years old). A total of 112 children underwent a game-based nutritional educational lesson on the importance of carbohydrates. For one group (n = 58), the lesson was carried out by a nutritional educator, the Master of Taste (MT), whereas for another group, (n = 54) the Master of Taste was supported by a humanoid robot (MT + NAO). A third group of children (n = 33) served as control not receiving any lesson. The intervention efficacy was evaluated by questionnaires administered at the beginning and at the end of each intervention. The nutritional knowledge level was evaluated by the cultural-nutritional awareness factor (AF) score. A total of 290 questionnaires were analyzed. Both MT and MT + NAO interventions significantly increased nutritional knowledge. At the end of the study, children in the MT and MT + NAO group showed similar AF scores, and the AF scores of both intervention groups were significantly higher than the AF score of the control group. This study showed a significant increase in the nutritional knowledge of children involved in a game-based, single-lesson, educational intervention performed by a figure that has a background in food science. However, the presence of a humanoid robot to support this figure's teaching activity did not result in any significant learning improvement. Copyright © 2016 The Royal Society for Public Health.

    Background: Improper nutritional knowledge is one of the most important causes of nutritional problems, which can affect practice and cause more complications. The aim of this study was to assess the association between nutritional knowledge, attitude and practice (KAP) of Iranian households with socioeconomic status (SES). Methods: The study population was 14,136 households (57 clusters of 8 individuals in each province) who lived in urban and rural regions of 31 provinces of Iran. The sample size of the study was selected using multistage cluster sampling technique. A structured questionnaire and interview with the qualified person in each family was used to collect data. The questionnaire included demographic, SES and nutritional KAP questions. Using principle component analysis, some variables including household assets, occupation and education level of the heads of the families and respondents and the number of family members were used to construct family SES. The SES was categorized as good, moderate and weak. Pearson's Chi-square test was used to analyze categorical variables. Results: The percentage of knowledge about growing up, acquiring energy and being healthy as reasons for eating food was 24.1%, 44.8% and 54.7%, respectively. Only 69.7%, 60.5% and 52.5% of the participants had knowledge of identification of meat and legumes, grain and dairy group, respectively. More than 97% of the participants had a favorable attitude toward importance of nutrition in health. The nutritional knowledge linearly increased with increasing SES. Families with good SES significantly consumed more fruit, vegetable, dairy group, red meat, chicken and poultry, fish and egg while sugar consumption was significantly higher in families with weak SES (pnutritional KAP. Some policies should be considered to increase nutritional KAP especially in lower SES group in the society.

    Hypoglycemia is a common problem among hospitalized patients. Treatment of hyperglycemia with insulin is potentially associated with an increased risk for hypoglycemia. The aim of this study was to determine the prevalence and predictors of hypoglycemia (capillary blood glucose parenteral nutrition (TPN). This prospective multicenter study involved 19 Spanish hospitals. Noncritically ill adults who were prescribed TPN were included, thus enabling us to collect data on capillary blood glucose and insulin dosage. The study included 605 patients of whom 6.8% (n = 41) had at least one capillary blood glucose <70 mg/dL and 2.6% (n = 16) had symptomatic hypoglycemia. The total number of hypoglycemic episodes per 100 d of TPN was 0.82. In univariate analysis, hypoglycemia was significantly associated with the presence of diabetes, a lower body mass index (BMI), and treatment with intravenous (IV) insulin. Patients with hypoglycemia also had a significantly longer hospital length of stay, PN duration, higher blood glucose variability, and a higher insulin dose. Multiple logistic regression analysis showed that a lower BMI, high blood glucose variability, and TPN duration were risk factors for hypoglycemia. Use of IV insulin and blood glucose variability were predictors of symptomatic hypoglycemia. The occurrence of hypoglycemia in noncritically ill patients receiving PN is low. A lower BMI and a greater blood glucose variability and TPN duration are factors associated with the risk for hypoglycemia. IV insulin and glucose variability were predictors of symptomatic hypoglycemia. Copyright © 2015 Elsevier Inc. All rights reserved.

  12. Nutritional requirements of the critically ill patient.

    The presence or development of malnutrition during critical illness has been unequivocally associated with increased morbidity and mortality in people. Recognition that malnutrition may similarly affect veterinary patients emphasizes the need to properly address the nutritional requirements of hospitalized dogs and cats. Because of a lack in veterinary studies evaluating the nutritional requirements of critically ill small animals, current recommendations for nutritional support of veterinary patients are based largely on sound clinical judgment and the best information available, including data from experimental animal models and human studies. This, however, should not discourage the veterinary practitioner from implementing nutritional support in critically ill patients. Similar to many supportive measures of critically ill patients, nutritional interventions can have a significant impact on patient morbidity and may even improve survival. The first step of nutritional support is to identify patients most likely to benefit from nutritional intervention. Careful assessment of the patient and appraisal of its nutritional needs provide the basis for a nutritional plan, which includes choosing the optimal route of nutritional support, determining the number of calories to provide, and determining the composition of the diet. Ultimately, the success of the nutritional management of critically ill dogs and cats will depend on close monitoring and frequent reassessment.

    Full Text Available Background: Malnutrition is a pathological state resulting from a relative or absolute deficiency or excess of one or more essential nutrients. Malnutrition is a major underlying cause of the child morbidity and mortality in Nepal. Adequate nutrition is a fundamental right for every human being. Malnourished child is depriving from physical and mental development. Objectives: To assess the nutritional status of children under 5 years and to find out the knowledge and practice regarding micronutrient powder “Baal vita” Materials and Methods: Descriptive cross sectional community based study was conducted in Palpa district, total of 390 respondents at the age of 6-59 months were selected with the help of multistage sampling. Through anthropometry, prevalence of underweight, stunting and wasting was determined. Results: Prevalence of underweight, stunting and wasting was 25.9%, 27.2% and 7.3% respectively. The association between age of the mother at the birth of the children and nutritional status of children is not statistically significant. Majority of the children (80.5% used to take junk foods sometimes, followed by 16.7% very often, 2.8% children never used to take. Majority of the children (52.6% were taken the micronutrient powder (first course but the coverage of second course of micronutrient powder was 29.5% and followed by third course coverage was only 18.9%. Conclusion: The nutritional status of children in this study were found to be satisfactory because compared to the Millennium Development Goals (MDGs target but the coverage of micronutrient powder is low.

    Few studies have explored how people living with multiple sclerosis (MS) cope with impairments and disability to participate in nutritional behaviors, such as meal preparation and grocery shopping. Thus, we conducted a qualitative study among eight individuals with MS who experienced mobility impairments. The eight individuals participated in semistructured, face-to-face interviews that focused on obtaining narratives about day-to-day dietary habits, preparing food, grocery shopping, and going to restaurants. Interviews were analyzed using an inductive category and theme development approach. Overall themes were (a) "it's a lot of work," (b) "it's not just up to me," (c) sifting through nutritional information, and (d) "why I eat what I eat." Participants frequently reported fatigue and mobility impairments as barriers to engagement in nutritional behaviors and often described family members as the "gatekeepers" for food selection and preparation (i.e., providing tangible support). Future research should explore the effectiveness of nutritional interventions that target family dynamics and create a supportive social environment to promote healthy eating habits and nutritional autonomy.

    Nutrition is important for preventing and treating chronic diseases highly prevalent among Latinos, yet no tool exists for measuring nutrition literacy among Spanish speakers. This study aimed to adapt the validated Nutrition Literacy Assessment Instrument for Spanish-speaking Latinos. This study was developed in two phases: adaptation and validity testing. Adaptation included translation, expert item content review, and interviews with Spanish speakers. For validity testing, 51 participants completed the Short Assessment of Health Literacy-Spanish (SAHL-S), the Nutrition Literacy Assessment Instrument in Spanish (NLit-S), and socio-demographic questionnaire. Validity and reliability statistics were analyzed. Content validity was confirmed with a Scale Content Validity Index of 0.96. Validity testing demonstrated NLit-S scores were strongly correlated with SAHL-S scores (r = 0.52, p internal consistency was excellent (Cronbach's α = 0.92). The NLit-S demonstrates validity and reliability for measuring nutrition literacy among Spanish-speakers.

    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.

    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 nutrition

    The study addresses the effectiveness of using ion exchange substrates (IES) to optimize mineral nutrition of plants grown in the nutrient solutions containing oxidized human wastes for application in bio-technical life support systems. The study shows that the addition of IES to the root-inhabited substrate is favorable for the growth of wheat vegetative organs but causes a decrease in the grain yield. By contrast, the addition of IES to the nutrient solution does not influence the growth of vegetative organs but favors normal development of wheat reproductive organs. Thus, to choose the proper method of adjusting the solution with IES, one should take into account specific parameters of plant growth and development and the possibility of multiple recycling of IES based on the liquid products of mineralization of human wastes.

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.

    Full Text Available Abstract Eicosanoids are major players in the pathogenesis of several common diseases, with either overproduction or imbalance (e.g. between thromboxanes and prostacyclins often leading to worsening of disease symptoms. Both the total rate of eicosanoid production and the balance between eicosanoids with opposite effects are strongly dependent on dietary factors, such as the daily intakes of various eicosanoid precursor fatty acids, and also on the intakes of several antioxidant nutrients including selenium and sulphur amino acids. Even though the underlying biochemical mechanisms have been thoroughly studied for more than 30 years, neither the agricultural sector nor medical practitioners have shown much interest in making practical use of the abundant high-quality research data now available. In this article, we discuss some specific examples of the interactions between diet and drugs in the pathogenesis and therapy of various common diseases. We also discuss, using common pain conditions and cancer as specific examples, how a better integration between agricultural science, nutrition and pharmacology could lead to improved treatment for important diseases (with improved overall therapeutic effect at the same time as negative side effects and therapy costs can be strongly reduced. It is shown how an unnaturally high omega-6/omega-3 fatty acid concentration ratio in meat, offal and eggs (because the omega-6/omega-3 ratio of the animal diet is unnaturally high directly leads to exacerbation of pain conditions, cardiovascular disease and probably most cancers. It should be technologically easy and fairly inexpensive to produce poultry and pork meat with much more long-chain omega-3 fatty acids and less arachidonic acid than now, at the same time as they could also have a similar selenium concentration as is common in marine fish. The health economic benefits of such products for society as a whole must be expected vastly to outweigh the direct

    Studies concerning the more appropriate criteria for evaluating oral health in relation to nutrition in the elderly vary greatly. There is a need to identify the most relevant criteria for classifying dental indicators of mastication in nutritional studies, so these indicators may be considered for epidemiological and clinical purposes. The aim of this study was to explore the associations between nutritional deficit and measures of oral health in a group of elderly. A convenience sample of independent elderly aged 65 years or more attending two primary care clinics in Beirut, Lebanon was selected. Data were collected from a questionnaire including the Mini-Nutritional Assessment (MNA), Geriatric Oral Health Assessment Index (GOHAI) and questions about perception of xerostomia and chewing problems. The oral examinations recorded decayed, missing and filled teeth (DMFT), the prosthetic status and the number of functional units (FU). The sample was composed of 121 women (mean age: 71.59 ± 5.97 years) and 80 men (mean age: 72.74 ± 6.98 years). They were allocated to two groups: 85 participants suffering from malnutrition (MNA score nutritional status (MNA score ≥ 24). Parameters that explain MNA variations were perception of xerostomia (OR = 3.49, 95% CI [1.66-7.34]), number of FU (OR = 2.79, 95% CI [1.49; 5.22]), and GOHAI score (OR = 2.905, 95% CI [1.40; 6.00]). Further studies exploring factors affecting nutrition in the elderly should take into consideration perception of xerostomia, number of FUs and GOHAI score. Copyright © 2013.

Aim: Assess factors associated with non-nutritive sucking habits in children after 3 years old. Materials and Methods: A case-control study was carried out in two stages. In the first stage, a cross-sectional study was conducted with 638 children aged 3-6 years. In the second stage, a case-control study (1:2 was conducted. The case group included all children who presented some non-nutritive sucking habits in the first stage of the study (n = 110. The control group (n = 220 was made up of children who had never presented non-nutritive sucking habits, matched to the case group for gender and age. The data were collected during the national poliomyelitis vaccination campaign, through a questionnaire applied to parents/guardians with questions related to the presence of sucking habits, sociodemographic aspects, birth aspects, and early life of the child. Statistical analysis involved descriptive analysis, chi-square test, Mann-Whitney test, and conditional logistic regression. Results: Reduction in maternal education was a protective factor for the development of non-nutritive sucking habits (education ≤8 years OR = 0.38, CI 95%: 0.16, 0.89, P = 0.025. Prematurity (OR = 3.30, CI 95%: 1.13, 9.69, P = 0.030 and a longer period using a baby bottle (OR = 1.03, CI 95%: 1.01, 1.05, P = 0.006 remained associated with a greater possibility of the occurrence of sucking habits, regardless of monthly family income. Conclusion: Non-nutritive sucking habits were associated with maternal education, premature birth, and greater time of bottle feeding in children after 3 years old.

    Involuntary weight loss (IWL) is frequent in advanced cancer patients causing compromised anticancer treatment outcomes and function. Cancer cachexia is influenced by nutrition impact symptoms (NIS). The aim of this study was to explore the frequency of NIS in advanced patients and to assess specific interventions guided by a 12-item NIS checklist. Consecutive patients from an outpatient nutrition-fatigue clinic completed the NIS checklist. The NIS checklist was developed based on literature review and multiprofessional clinical expert consensus. Chart review was performed to detect defined NIS typical interventions. Oncology outpatients not seen in the nutrition-fatigue clinic were matched for age, sex, and tumor to serve as controls. In 52 nutrition-fatigue clinic patients, a mixed cancer population [IWL in 2 months 5.96 % (mean)], the five most frequent NIS were taste and smell alterations 27 %, constipation 19 %, abdominal pain 14 %, dysphagia 12 %, and epigastric pain 10 %. A statistically significant difference for NIS typical interventions in patients with taste and smell alterations (p = 0.04), constipation (p = 0.01), pain (p = 0.0001), and fatigue (p = 0.0004) were found compared to the control population [mixed cancer, 3.53 % IWL in 2 months (mean)]. NIS are common in advanced cancer patients. The NIS checklist can guide therapeutic nutrition-targeted interventions. The awareness for NIS will likely evoke more research in assessment, impact, and treatment.

    During solitary sailing the sailor is exposed to sleep deprivation and difficulties in consuming regular meals. Sailor weight loss is often reported. In the present case study we describe changes in the physical capacity and the nutritional status of an athlete attempting a single-handed yacht race around the globe. An Italian male ocean racer (GM) asked for our help to reach an optimum level of physical and nutritional preparation. We planned his diet after assessing his anthropometric parameters and body composition as well as his usual energy intake and nutritional expenditure. The diet consisted in 120 meals stored in sealed plastic bags. Before his departure, GM performed two incremental exercise tests (cycle- and arm crank- ergometry) to assess his physical capacity. Cardiac functions were also estimated by Doppler echocardiography. All measures and exercise tests were repeated 10 days after GM finished the race, which lasted 64 days. Anthropometric measures did not change significantly, with the exception of Arm Fat Area and Thigh Muscle area, which decreased. There were evident increments in maximum oxygen intake and maximum workload during arm cranking after the race. On the contrary, maximum oxygen uptake and maximum workload decreased during cycling. Finally, End Diastolic and Stroke Volume decreased after the race. It was concluded that nutritional counseling was useful to avoid excessive changes in the nutritional status and body composition due to 64 days of solitary navigation. However, a reduction in physical leg capacity and cardiovascular functions secondary to legs disuse were present.

    Nutritional support for surgical care is crucial because hospital malnutrition is rather common. However, low- and middle-income countries have not adequately addressed nutritional management of surgical patients. To highlight need for nutritional management in surgical patients, the present study aimed to describe preoperative nutritional status in patients who underwent gastrointestinal cancer surgery in Vietnam and to investigate the relationship between preoperative malnutrition and adverse outcomes, such as postoperative complications and prolonged length of hospital stay. We reviewed medical records of patients who underwent a major curative surgery for gastrointestinal cancer at the national hospital in Ho Chi Minh City, Vietnam. We identified preoperative malnutrition based on body mass index and serum albumin level, and postoperative complications in the first 30 d postoperative. We estimated the relative influence of malnutrition on complications and length of hospital stay using multivariate regression models. Of 459 eligible patients, 63% had colorectal cancer, 33% gastric cancer, and 4% esophageal cancer. The prevalence of malnutrition was 19%. No patients died during hospitalization; however, 26% developed complications after surgery. The average length of hospital stay was 14 d. After controlling for potential confounders, preoperative malnutrition was associated with an increased risk of postoperative complications (odds ratio = 1.97) and prolonged hospital stay (2.8 d). Preoperative malnutrition affects surgical outcomes among patients with gastrointestinal cancer in Vietnam. We recommend implementing preoperative nutritional interventions to achieve better outcomes among surgical cancer patients. Copyright © 2017 Elsevier Inc. All rights reserved.

  11. Nutritional Ketosis and Mitohormesis: Potential Implications for Mitochondrial Function and Human Health

    Science.gov (United States)

    Villamena, Frederick A.

    2018-01-01

    Impaired mitochondrial function often results in excessive production of reactive oxygen species (ROS) and is involved in the etiology of many chronic diseases, including cardiovascular disease, diabetes, neurodegenerative disorders, and cancer. Moderate levels of mitochondrial ROS, however, can protect against chronic disease by inducing upregulation of mitochondrial capacity and endogenous antioxidant defense. This phenomenon, referred to as mitohormesis, is induced through increased reliance on mitochondrial respiration, which can occur through diet or exercise. Nutritional ketosis is a safe and physiological metabolic state induced through a ketogenic diet low in carbohydrate and moderate in protein. Such a diet increases reliance on mitochondrial respiration and may, therefore, induce mitohormesis. Furthermore, the ketone β-hydroxybutyrate (BHB), which is elevated during nutritional ketosis to levels no greater than those resulting from fasting, acts as a signaling molecule in addition to its traditionally known role as an energy substrate. BHB signaling induces adaptations similar to mitohormesis, thereby expanding the potential benefit of nutritional ketosis beyond carbohydrate restriction. This review describes the evidence supporting enhancement of mitochondrial function and endogenous antioxidant defense in response to nutritional ketosis, as well as the potential mechanisms leading to these adaptations.

    Few data is available on the nutritional status of old Chinese. The present study aimed to describe the nutritional status and clinical correlates for malnutrition risk in the older people. Cross-sectional study. Hospital- and community-based older people were recruited in the region of Chongqing, China. 558 individuals aged 60 years old or over between April 2011 and October 2012. Comprehensive geriatric assessment was performed and nutritional status was assessed by the Mini Nutritional Assessment Short Form (MNA-SF). Nutrition-associated factors were analyzed, including health status (chronic diseases, depression, cognition, function impaired), social factors (education status, marital status, the type of work before 60 years old) and life style factors (smoking, drinking, diet). The mean age was 73.1±8.0 years and 43.9% were men. Prevalence of malnutrition and risk for malnutrition were 3.2% and 19.3 %, respectively. Several factors increased poor nutrition independently including self-rated health, comorbidity, chronic obstructive pulmonary disease, gastrointestinal disease and cognitive impairment. Fish decreased the risk of poor nutrition. The prevalence was relatively low in older people of Chongqing, Southwest China. Poor nutrition was found to be increased due to the common health problems. Thus the patients with these problems should pay more attention on nutritional status. The older people should often have fish because of their nutritional benefit.

    The rising of individualized therapy requires nutritional risk screening has become a major topic for each particular disease, yet most of the screenings were for malignancies, less for benign diseases. There is no report on the screening of patients with benign liver tumors postoperatively. We aim to evaluate the nutritional support strategies post operation for benign liver tumors through nutritional risk screening. In this prospective, randomized, controlled study, 95 patients who underwent hepatectomy for benign tumors were divided into two groups. Fifty patients in the control group were given routine permissive underfeeding nutritional supply (75 kJ/kg/d), and 45 patients in the experimental group were given lower energy (42 kJ/kg/d) in accordance of their surgical trauma. Routine blood tests, liver/kidney function were monitored before surgery and at the day 1, 3, 5, 9 after surgery, patients were observed for the time of flatus, complications, length of hospitalization (LOH), nutrition-related costs, and other clinical parameters. This completed study is registered with Clinicaltrials.gov, number NCT01292330. The nutrition-related expenses (494.0±181.0 vs. 1,514.4±348.4 RMB, Pgroup were significantly lower than those in the control group. Meanwhile, the lowered energy supply after the surgeries did not have adverse effects on clinical parameters, complications, and LOH. Patient with benign liver tumors can adopt an even lower postoperative nutritional supply that close to that for mild non-surgical conditions, and lower than the postoperative permissive underfeeding standard.

    Full Text Available Yerba mate is defined as the product constituted by the dried, slightly roasted, and milled leaves of Ilex paraguariensis. However, the fruits of this species are often found in the commercial product. Nowadays the fruits are considered a byproduct. The objective of this work was to obtain the preliminary data of minerals, lipids, methylxanthines and polyphenols in the ripe fruits of I. paraguariensis. The results showed a considerable amount of total dietary fiber (42.0 ± 1.6 g/100 g and nutritionally valuable minerals: potassium (1324 ± 15 mg/100 g, iron (6.4 ± 0.5 mg/100 g, magnesium (168 ± 15 mg/100 g, calcium (150 ± 12 mg/100 g, copper (1.1 ± 0.1 mg/100 g, zinc (2.3 ± 0.3 mg/100 g, and sodium (1.3 ± 0.1 mg/100 g. The lipid content was 4.5 g/100 g. Oleic acid was the predominant unsaturated fatty acid (38.74 ± 0.75 g/100 g. Linoleic acid (1.83 ± 0,01 g/100 g was also present. Methylxanthines were quantified: caffeine (0.118 ± 0.001 and theobromine (0.0125 ± 0.0002 g/100 g. The total polyphenol content was 0.717 ± 0.001 g/100 g. The results obtained in this work suggest the potential value of the fruits of I. paraguariensis for the development of novel products in the food and pharmaceutical industries. This paper aims to contribute to the scientific knowledge of a natural by-product from industry regarding the need of foods and medicines for the new millennium.

    Refeeding syndrome is a potentially life-threatening condition characterised by severe intracellular electrolyte shifts, acute circulatory fluid overload and organ failure. The initial symptoms are non-specific but early clinical features are severely low-serum electrolyte concentrations of potassium, phosphate or magnesium. Risk factors for the syndrome include starvation, chronic alcoholism, anorexia nervosa and surgical interventions that require lengthy periods of fasting. The causes of the refeeding syndrome are excess or unbalanced enteral, parenteral or oral nutritional intake. Prevention of the syndrome includes identification of individuals at risk, controlled hypocaloric nutritional intake and supplementary electrolyte replacement. To determine the occurrence of refeeding syndrome in adults commenced on artificial nutrition support. Prospective cohort study. Large, single site university teaching hospital. Recruitment period 2007-2009. 243 adults started on artificial nutrition support for the first time during that admission recruited from wards and intensive care. occurrence of the refeeding syndrome. Secondary outcome: analysis of the risk factors which predict the refeeding syndrome. Tertiary outcome: mortality due to refeeding syndrome and all-cause mortality. 133 participants had one or more of the following risk factors: body mass index 15% in the preceding 3-6 months, very little or no nutritional intake >10 days, history of alcohol or drug abuse and low baseline levels of serum potassium, phosphate or magnesium prior to recruitment. Poor nutritional intake for more than 10 days, weight loss >15% prior to recruitment and low-serum magnesium level at baseline predicted the refeeding syndrome with a sensitivity of 66.7%: specificity was >80% apart from weight loss of >15% which was 59.1%. Baseline low-serum magnesium was an independent predictor of the refeeding syndrome (p=0.021). Three participants (2% 3/243) developed severe electrolyte shifts

    Full Text Available Bacteria colonizing the human intestinal tract exhibit a high phylogenetic diversity that reflects their immense metabolic potentials. The catalytic activity of gut microbes has an important impact on gastrointestinal (GI functions and host health. The microbial conversion of carbohydrates and other food components leads to the formation of a large number of compounds that affect the host metabolome and have beneficial or adverse effects on human health. Meabolomics is a metabolic-biology system approach focused on the metabolic responses understanding of living systems to physio-pathological stimuli by using multivariate statistical data on human body fluids obtained by different instrumental techniques. A metabolomic approach based on an analytical platform could be able to separate, detect, characterize and quantify a wide range of metabolites and its metabolic pathways. This approach has been recently applied to study the metabolic changes triggered in the gut microbiota by specific diet components and diet variations, specific diseases, probiotic and synbiotic food intake.This review describes the metabolomic data obtained by analyzing human fluids by using different techniques and particularly Gas Chromatography Mass Spectrometry Solid-phase Micro Extraction (GC-MS/SPME, Proton Nuclear Magnetic Resonance (1H-NMR Spectroscopy and Fourier Transform Infrared (FTIR Spectroscopy. This instrumental approach have a good potential in the identification and detection of specific food intake and diseases biomarkers.

    Esophageal cancer (EC) is increasing in prevalence due to rising incidence and improved treatment strategies. Dysphagia is a significant morbidity in patients with EC requiring nutritional intervention. We sought to evaluate outcomes of nutritional interventions for EC patients hospitalized with dysphagia at a population level. The National Inpatient Sample (2002-2012) was utilized to include all adult inpatients (≥18 years of age) with EC and presence of dysphagia and stricture that underwent nutritional interventions including feeding tube (FT) placement, esophageal stenting, or parenteral nutrition (PN). Temporal trends were examined with multivariate analysis performed for mortality, length of stay (LOS), and cost of hospitalization. A total of 509,593 EC patients had 12,205 hospitalizations related to dysphagia. The hospitalization rates doubled over the study period (1.52% vs. 3.28%, p esophageal stenting (13%), and PN (11%). PN was more frequently associated with a diagnosis of sepsis (6.1%, p = 0.023) compared to FT (2.5%) or esophageal stenting (1.8%). Multivariate analysis demonstrated FT and esophageal stenting had comparable mortality (OR 1.06, 95% CI: 0.49, 2.32); however, PN was associated with higher mortality (OR 2.37, 95% CI: 1.22, 4.63), cost of hospitalization ($5,510, 95% CI: 2,262, 8,759), and LOS (2.13 days, 95% CI: 0.72, 3.54). This study shows that hospitalizations for EC with dysphagia and related nutritional interventions are increasing. As a single modality, parenteral nutrition should be avoided. Among our esophageal stent and FT population, further studies are necessary to determine adequate interventions based on disease stage. © The Authors 2017.

    The present study aimed to assess the effects of Ramadan intermittent fasting on body weight and composition and the effects of age and sex. Body weight, height, waist and hip circumferences were measured, body mass index (BMI) was calculated and fat mass, fat-free mass and percentage body fat were assessed by bioelectrical impedance on 240 adult subjects (male: 158) who fasted between sunrise and sunset for at least 20 days. Measurements were taken 1 week before and 1 week after Ramadan. Energy and macronutrient intakes were assessed using a 3-day food frequency questionnaire on a sub-sample of subjects before and during Ramadan. Subjects were grouped according to age and sex: ≤35 years (n = 82, males: 31) and 36-70 years (n = 158, males: 127). There were significant reductions in weight and BMI (P Ramadan, except in males whose protein intake fell during Ramadan (P = 0.032).

    Worksite dietary interventions show substantial potential for improving employee health and well-being. The aim of this pilot study was to determine the effect of a worksite nutrition intervention on improving well-being. Thirty-five university employees participated in a 6-week nutrition intervention. The dietary protocol emphasized the daily consumption of greens, beans/legumes, a variety of other vegetables, fruits, nuts, seeds, and whole grains, referred to as a micronutrient-dense, plant-rich diet. Participants were encouraged to minimize the consumption of refined foods and animal products. Significant improvements in sleep quality, quality of life, and depressive symptoms were found. Findings reveal that a worksite nutrition intervention is effective at improving sleep quality, quality of life, and depressive symptoms with a projected improvement in work productivity and attendance.

    Factors influencing nutritional supplement use by high school students were assessed. Comparisons were made between various groups of sports participants and non-sports participants. The Nutritional Supplement Use and Knowledge Scale was administered to 509 students. Mean supplement use score was 10.87 (SEM = 0.50, range 0-57). Mean knowledge score was 13.56 (SEM = 0.16, range 1-21). Significant relationships (p knowledge with use, and supplement use with gender. ANOVA found significant differences between supplement use by gender (p knowledge scores by sports category (p knowledge, supplement use, and subscores for protein, vitamins/minerals, knowledge, supplement use, and subscores for protein, vitamins/minerals, and carbohydrates were best discriminators of sport group membership. Greater knowledge about supplements was associated with less use; hence, education about supplements can be a deterrent to use. This study may help coaches, athletic trainers, athletic directors, teachers, physicians, and parents identify nutritional misconceptions held by adolescents.

    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.

    The relationship between malaria infection and nutritional status is complex and previous studies suggest malaria may increase the incidence and severity of malnutrition while malnutrition may increase the risk of malaria infection. Here, we report bi-directional associations between malaria and nutritional status among children with uncomplicated severe acute malnutrition (SAM). The present study is a secondary analysis of a randomized controlled trial for the treatment of uncomplicated SAM in Niger. Children between 6-59 months were enrolled and followed for 12 weeks. Malaria infection was assessed using an HRP2 rapid diagnostic test at admission and at any follow-up visit with fever. We assessed the association of 1) nutritional status at admission on malaria incidence using Cox proportional hazards regression, and 2) malaria infection at admission on nutritional recovery, weight and height gain using linear regression. Of 2,399 children included in the analysis, 1,327 (55.3%) were infected with malaria at admission. Malaria incidence was 12.1 cases per 100 person-months among those without malaria infection at admission. Nutritional status at admission was not associated with malaria incidence. Children with malaria infection at admission, subsequently treated with an artemisinin based combination therapy, had increased weight gain (0.38 g/kg/day, 95% confidence interval [CI] 0.07 to 0.69) and reduced height gain (-0.002 mm/day, 95% CI -0.004 to -0.0008). Malaria infection was common among children treated for uncomplicated SAM. Malaria infection may impair height gain. Proper medical and nutritional management should be assured to prevent adverse effects of malaria infection.

    Several studies have suggested that malnutrition impedes functional recovery in patients with hip fracture, but there are few reports on improvement in nutritional status and return to activities of daily living (ADL) in these patients. This study was conducted to evaluate the relationship between change in nutritional status and recovery of ADL in malnourished patients after hip fracture and to identify predictors of functional recovery among the characteristic features of undernutrition. This was a retrospective observational cohort study. Data for patients aged ≥65 years with hip fracture and malnutrition (Mini Nutritional Assessment-Short Form [MNA-SF] score ≤7) at the time of admission to convalescent rehabilitation units were obtained from the Japan Rehabilitation Nutrition Database between November 2015 and August 2017. The main outcome measures were Functional Independence Measure (FIM) at discharge and the proportion of patients discharged home. Patients were divided into two groups based on MNA-SF scores at discharge: improvement in nutritional status (>7, IN group) and non-improvement in nutritional status (≤7, NN group). Clinical characteristics and outcomes were compared between the groups. Multivariable regression analysis was performed to adjust for confounders including age, sex, comorbidity, pre-fracture ADL level, and FIM score on admission. Of 876 patients, 110 met the eligibility criteria (mean age, 85 years; 78.2% female); 77 of the patients were assigned to the IN group and 33 to the NN group. The patients in the IN group were younger and had higher FIM and MNA-SF scores on admission than those in the NN group. At discharge, the median FIM score was significantly higher in the IN group than in the NN group (110 vs 83, Pnutritional status and higher FIM score at discharge (B=7.377 [B=partial regression coefficient], P=0.036) but no association with discharge to home.

    The aims of this study were to report nutritional status in a large panel of patients with cancer requiring exclusive chemotherapy and to study the influence of nutritional status on their quality of life (QoL). This work was a longitudinal cohort study performed at a French university teaching hospital. Eligible patients were individuals with a cancer needing treatment based on exclusive chemotherapy. Three work-ups were performed: i) before the administration of the first course of chemotherapy: T1, ii) before the administration of the second (for patients with 3 planned courses) or third (patients with 6 planned courses) course: T2, and iii) before the administration of the last planned course: T3. The following data were collected: general health (performance status) and nutritional status (weight, anorexia grading, albuminemia, pre-albuminemia, and C-reactive protein) and QoL. The nutritional status of patients with cancer was preserved. Functional impairment, the presence of anorexia, the palliative nature of the chemotherapy, and an elevated C-reactive protein dosage were independent predictive factors of a lower QoL among patients assessed at the end of chemotherapy. Although larger studies should corroborate these findings, clinicians may include this information in the management of patients with cancer requiring exclusive chemotherapy to identify the most vulnerable patients.

    Nutritional status may influence quality of life and prognosis among pancreatic cancer patients, yet few studies describe measures of nutritional status during treatment. We evaluated the nutritional status of locally advanced pancreatic cancer (LAPC) patients undergoing chemoradiotherapy who received baseline nutritional assessment and counseling. Fourteen newly diagnosed LAPC patients enrolled in phase I/II trials of capecitabine with concomitant radiotherapy were assessed for baseline clinical nutrition measures (body mass index, albumin, weight loss, total energy, and protein intake). Participants completed the Anorexia/Cachexia Subscale (A/CS) questionnaire at baseline and during the 6 weeks of treatment. We evaluated associations between baseline characteristics and subsequent A/CS scores with linear regression and changes in A/CS were assessed with the paired t test. We observed a statistically significant increase in mean A/CS between baseline [24.9, standard deviation (SD) = 9.7] and end of treatment (29.9, SD = 6.2). Controlling for baseline A/CS score, only weight loss greater than 5% of body weight over 1 month was associated with A/CS scores at 6 weeks (β = 10.558, standard error = 3.307, p value = 0.009) and mean A/CS scores during the last 3 weeks of treatment (β = 12.739, standard error = 2.251, p value = 0.001). After 6 weeks of chemoradiotherapy, LAPC patients reported a statistically significant improvement in appetite and weight concerns. Increases in AC/S scores were associated with higher baseline A/CS scores and weight loss of 5% or more during 1 month. Further research is needed to determine the impact of nutritional support during treatment, as improvements in this domain may impact LAPC patients' overall quality of life.

    This paper presents a physico-chemical study of the interaction of radiation with skin by ionizing radiation, presenting the hazards caused by the process. Throughout the work it is shown the importance of cellular nutrition during the period of radiotherapeutic treatment, besides having updated data on the application of natural substances for the regeneration of the place submitted to the treatment. Cancer is a problem of public health and according to data provided by the National Cancer Institute José Alencar Gomes da Silva (INCA), 420,310 new cases were registered in Brazil in 2016, of which 214,350 are among women (primary location 'breast') and 205,960 among male (primary location 'prostate'). Despite advances in technology, the hazards caused by ionizing radiation in contact with the skin are high degree of aggressiveness. Therefore, there is great importance in developing scientific studies in order to evaluate and minimize its damages during its application for radiotherapeutic purposes. The use of Aloe Vera (extracted from the slug) on the irradiated site is easily found among people undergoing radiation therapy. How is it about a stimulator of cellular and healing multiplication favors the tissue regeneration, becoming important its application, due to the radiodermatitis that appear during the treatment. Thus, the objective of this work is to present a bibliographic study of the mechanisms related to the interaction of radiation with matter, as well as the beneficial effects of the substance on irradiated living tissue and to expose such data in graph and tables to quantify its use

    INTRODUCTION In preterm neonates, peroxides contaminating total parenteral nutrition (TPN) contribute to oxidative stress, which is suspected to be a strong inducer of hepatic complications related to prematurity. Recently, others reported that hexapeptides derived from human milk (HM) exerted free radical–scavenging activities in vitro. Therefore, the aim of this study was to assess the capacity of these hexapeptides to limit the generation of peroxides in TPN and to prevent TPN-induced hepatic oxidative stress. METHODS At 3 d of life, guinea pigs were infused, through a catheter in jugular vein, with TPN containing or not peptide-A (YGYTGA) or peptide-B (ISELGW). Peroxide concentrations were measured in TPN solutions, whereas glutathione, glutathionyl-1,4-dihydroxynonenal (GS-HNE) and mRNA levels of interleukin-1 (IL-1) and tumor necrosis factor-α (TNFα) were determined in liver after 4 d of infusion. RESULTS The addition of peptide-A to TPN allowed a reduction in peroxide contamination by half. In vivo, peptide-A or peptide-B corrected the hepatic oxidative status induced by TPN. Indeed, both peptides lowered the hepatic redox potential of glutathione and the level of GS-HNE, a marker of lipid peroxidation. As compared with animals infused with TPN without peptide, the hepatic mRNA levels of IL-1 and TNFα were lower in animals infused with TPN containing peptide-A or peptide-B. DISCUSSION These results suggest that the addition of YGYTGA or ISELGW to TPN will reduce oxidative stress in newborns. The reduction in mRNA of two proinflammatory cytokines could be important for the incidence of hepatic complications related to TPN. PMID:22337230

    Malnutrition is very common among chronically hospitalized patients, especially those in the intensive care unit (ICU). Identifying the patients at risk and providing suitable nutritional support can prevent and/or overcome malnutrition in them. Total parenteral nutrition (TPN) and partial parenteral nutrition (PPN) are two common routes to deliver nutrition to hospitalized patients. We conducted a multicenter, prospective double blind randomized controlled trial to evaluate the benefits and compare their adverse effects of each method. 97 patients were enrolled and divided into two groups based on the inclusion criteria. Serum protein, serum albumin, serum transferrin, and total lymphocyte count were measured on days 7 and 14. We did not find any statistically significant differences in clinical status or laboratory values between the two groups but there were significant improvements in measured lab values between days 7 and 14 (pnutritional status in each groups. This study shows that both TPN and PPN can be used safely in chronic ICU patients to provide nutritional support and prevent catabolic state among chronic critically ill patients. We need to develop precise selection criteria in order to choose the patients who would benefit the most from TPN and PPN. In addition, appropriate laboratory markers are needed to monitor the metabolic requirements of the patients and assess their progress.

    Full Text Available Maize or corn (Zea mays L. is an important cereal crop of the world. It is a source of nutrition as well as phytochemical compounds. Phytochemicals play an important role in preventing chronic diseases. It contains various major phytochemicals such as carotenoids, phenolic compounds, and phytosterols. It is believed to have potential anti-HIV activity due to the presence of Galanthus nivalis agglutinin (GNA lectin or GNA-maize. A tablespoon of maize oil satisfies the requirements for essential fatty acids for a healthy child or adult. Decoction of maize silk, roots, leaves, and cob are used for bladder problems, nausea, vomiting, and stomach complaints. Zein an alcohol-soluble prolamine found in maize endosperm has unique novel applications in pharmaceutical and nutraceutical areas. Resistant starch (RS from maize reduces the risk of cecal cancer, atherosclerosis, and obesity-related complications.

    Analytic advances are enabling more precise definitions of the molecular composition of key food staples incorporated into contemporary diets and how the nutrient landscapes of these staples vary as a function of cultivar and food processing methods. This knowledge, combined with insights about the interrelationship between consumer microbiota configurations and biotransformation of food ingredients, should have a number of effects on agriculture, food production, and strategies for improving the nutritional value of foods and health status. These effects include decision-making about which cultivars of current or future food staples to incorporate into existing and future food systems, and which components of waste streams from current or future food manufacturing processes have nutritional value that is worth capturing. They can also guide which technologies should be applied, or need to be developed, to produce foods that support efficient microbial biotransformation of their ingredients into metabolic products that sustain health.

    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.

    To determine the relationship between denture wearing and nutritional status in the elderly with dementia. There could be a correlation between nutrition, oral health, dietary habits, patients' satisfaction, and their socio-economic status in the elderly, and the relationship between compromised oral status and nutritional status in the elderly with dementia. A 2-year follow-up study of 63 elderly Japanese women with and without dentures from a nursing home was undertaken to investigate their oral, physical and mental, and nutritional status. Each item for 2006 and 2008 in this study showed no significant difference between 2006 and 2008, except the calories/day. The elderly with dementia without complete dentures during the 2 years of the study only significantly decreased the mean of the calories/day. The calories/day of the elderly with dementia without dentures decreased after 2 years. Denture wearing for the elderly with dementia could be necessary to maintain a satisfactory intake of calories. © 2011 The Gerodontology Society and John Wiley & Sons A/S.

    Full Text Available Calcium is an important nutrient for child development. The main objective of this study was to assess calcium intake and its adequacy with dietary reference intake (DRI in Spanish children. The ANIVA (Antropometría y Nutrición Infantil de Valencia study is a descriptive cross-sectional study. During two academic years 2013–2014 and 2014–2015, 1176 schoolchildren aged 6–9 years were selected from 14 primary schools in Valencia (Spain. Three-day food records were used to assess dietary intake, completed by parents/guardian. Anthropometric data (weight and height were evaluated in all subjects. Nutritional intake was compared to estimated average requirements (EARs and adequate intake (AI values to determine nutritional adequacy. A percentage of 25.77% had inadequate calcium intake, and a significantly higher prevalence was observed in girls (p = 0.006. Adequate calcium intake showed a positive association with the height z-score (p = 0.032. When assessing dietary patterns, schoolchildren with adequate calcium intakes had better nutritional adequacy in all nutrients, except cholesterol (p = 0.086 and fluorine (p = 0.503. These results suggest a public health problem that must be addressed through nutrition education programs to increase intake of calcium-rich food and to correct the associated dietary pattern.

    Lack of reliable assays for DNA repair has largely prevented measurements of DNA repair from being included in human biomonitoring studies. Using newly developed modifications of the comet assay we tested whether a fruit- and antioxidant-rich plant-based intervention could affect base excision repair (BER) and nucleotide excision repair (NER) in a group of 102 male volunteers. BER and NER repair capacities were measured in lymphocytes before and after a dietary intervention lasting 8 weeks. The study had one control group, one group consuming three kiwifruits per day and one group consuming a variety of antioxidant-rich fruits and plant products in addition to their normal diet. DNA strand breaks were reduced following consumption of both kiwifruits (13%, p = 0.05) and antioxidant-rich plant products (20%, p = 0.02). Increased BER (55%, p = 0.01) and reduced NER (-39%, p plant products. Reduced NER was also observed in the kiwifruit group (-38%, p = 0.05), but BER was not affected in this group. Here we have demonstrated that DNA repair is affected by diet and that modified versions of the comet assay can be used to assess activity of different DNA repair pathways in human biomonitoring studies.

    The immune system is particularly challenged in transition cows as marked physiological changes occur in this period which are driven by late gestation, partus and onset of lactation. As a consequence, the metabolic and nutritional state of the cow also changes significantly with possible implications for the plasticity and flexibility of the immune system. In order to understand how the balance between metabolism, nutritional status and the immune system is maintained under challenging conditions, such as an infection, various animal models can be used which specifically manipulate the nutritional status through various feeding and management strategies. Such models aim at exploring the immunological response to a challenge under largely varying nutritional and metabolic states. As energy balance (EB) is strongly associated both with the metabolic state and with the immunoreactivity of the cows the manipulation of the EB by either influencing energy intake or energy excretion with milk, or by both, offers model opportunities for studying EB effects on the immune system. For example, assigning cows with a higher body condition score (BCS) at least 6 weeks prior to calving to an energy-dense diet exceeding the energy requirement in combination with a decelerated increase in the concentrate feed proportion post partum was shown to be effective in inducing a ketotic metabolic state under ad libitum feeding conditions. Compared to an adequately managed control group this model allows studying immune responses in the transit period and in dependence on dietary interventions. Copyright © 2018 Elsevier Ltd.

    2017-04-01

    Full Text Available Genetics is an important piece of every individual health puzzle. The completion of the Human Genome Project sequence has deeply changed the research of life sciences including nutrition. The analysis of the genome is already part of clinical care in oncology, pharmacology, infectious disease and, rare and undiagnosed diseases. The implications of genetic variations in shaping individual nutritional requirements have been recognised and conclusively proven, yet routine use of genetic information in nutrition and dietetics practice is still far from being implemented. This article sets out the path that needs to be taken to build a framework to translate gene–nutrient interaction studies into best-practice guidelines, providing tools that health professionals can use to understand whether genetic variation affects nutritional requirements in their daily clinical practice.

    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.

    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

    To discover the views of children with severe intestinal failure treated with intravenous nutrition from early life and who remained heavily dependent on treatment throughout childhood. Seven children ages 7 to 17 years (mean 13 years) were interviewed. The diagnoses were enteropathy in 3, extreme short gut in 1, complex (associated mucosal inflammation and dysmotitlity) in 2, and intestinal pseudo-obstruction in 1. They were treated with intravenous nutrition overnight at home that was administered by trained parents using the simplest possible system. The children were individually questioned about their lifestyle and health. Transcripts were analysed using interpretive phenomenological analysis. Children coped well with life with intravenous nutrition (apart from septicaemia in 2 cases), but were troubled when complications of the underlying disease persisted (eg, nocturnal disturbance, stool frequency, abdominal pain). Children were aware that life was restricted (eg, fewer sleepovers with friends, fewer late nights out). There was a high level of family functioning. Older children wished to take care of themselves. The burdens of life with intravenous nutrition appear to be less significant for these children than living with the effects of chronic illness. There was resilience and acceptance in the face of illness-related demands. This study has found that despite the problems they may face, it is possible for children fed intravenously at home to develop a level of resilience, maintain a positive outlook, and cope well with illness-related demands even when they have had virtually lifelong severe intestinal failure. Families can continue to function well.

    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.

    To study the adolescence opinions' among nutritional habits and beliefs. To conduct a multi disciplinary approach through involving adolescence/youth for finding their mental needs and their suggestion for solving them, we designed a qualitative approach based on grounded theory. For data collection a semi-structured guide questioner designed and 16 focus group discussions were conducted by trained peers with youth aged 10-19 years. According to FGDs results, although majority of participants agreed on the important role of nutrition in health and the effect of nutritional habits on different aspect of health, they used modern and publicized fast foods. On the other hand, most of female and male participants said that different factors influenced the girls and boys diet selection i. e. girls' paid more attention to diet selection and taste and health of foods, whereas boys were careless and gluttony caused more food to be consumed. Adolescents' information (both genders) regarding nutritional problems resulting from improper food habits were not satisfactory. Peer-based health programmes through target groups for capacity building and participation of stakeholders will fulfill the objectives.

    We analyzed the relations between nutritional status and several measures of the ability to perform the normal activities of daily living (ADL) in a long-term institutionalized geriatric population and also studied whether changes in this ability, as found ten months later, were associated with changes in the nutritional status. Nutritional status was assessed using objective anthropometric measurements (triceps skinfold, mid upper-arm circumference, midarm muscle area [AMA], midarm fat area [AFA]) and subjective clinical features (temporal muscle atrophy [TMA] and Bichat's fat atrophy [BFA]). The capacity to perform ADL was analyzed considering ability to eat and to walk, dental status, and mental performance status. Patients with total absence or loss of more than 50% of the teeth showed less AMA and AFA and greater degrees of TMA and BFA; the same happened with regard to deterioration of mental performance status. Those patients fed through a nasogastric tube showed less AFA and serum albumin and also a greater degree of TMA and BFA. Patients unable to walk without aid showed less AMA and AFA. Patients whose capacity to walk improved or whose mental performance status ameliorated showed an increase of their AMA, whereas AFA slightly decreased in those patients whose abilities to eat and to walk deteriorated. Long-term hospitalization in our center led to improvement and to deterioration of ADL in approximately the same number of patients, and similar changes were seen in the nutritional measures.

    This review aims to clarify the use of indirect calorimetry (IC) in nutritional therapy for critically ill and other patient populations. It features a comprehensive overview of the technical concepts, the practical application and current developments of IC. Pubmed-referenced publications were analyzed to generate an overview about the basic knowledge of IC, to describe advantages and disadvantages of the current technology, to clarify technical issues and provide pragmatic solutions for clinical practice and metabolic research. The International Multicentric Study Group for Indirect Calorimetry (ICALIC) has generated this position paper. IC can be performed in in- and out-patients, including those in the intensive care unit, to measure energy expenditure (EE). Optimal nutritional therapy, defined as energy prescription based on measured EE by IC has been associated with better clinical outcome. Equations based on simple anthropometric measurements to predict EE are inaccurate when applied to individual patients. An ongoing international academic initiative to develop a new indirect calorimeter aims at providing innovative and affordable technical solutions for many of the current limitations of IC. Indirect calorimetry is a tool of paramount importance, necessary to optimize the nutrition therapy of patients with various pathologies and conditions. Recent technical developments allow broader use of IC for in- and out-patients. Copyright © 2016 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism. All rights reserved.

    Multimodality treatment improves the chance of survival but increases the risk for long-term side effects in young cancer survivors, so-called" Adolescents and Young Adults"(AYAs). Compared to the general population AYAs have a 5 to 15-fold increased risk of cardiovascular morbidity. Thus, improving modifiable lifestyle risk factors is of particular importance. The INAYA trial included AYAs between 18 and 39 years receiving an intensified individual nutrition counseling at four time points in a 3-month period based on a 3-day dietary record. At week 0 and 12 AYAs got a face-to-face counseling, at week 2 and 6 by telephone. Primary endpoint was change in nutritional behavior measured by Healthy Eating Index - European Prospective Investigation into Cancer and Nutrition (HEI-EPIC). Twenty-three AYAs (11 female, 12 male, median age 20 years (range 19-23 years), median BMI: 21.4 kg/m 2 (range: 19.7-23.9 kg/m 2 ) after completion of cancer treatment for sarcoma (n = 2), carcinoma (n = 2), blastoma (n = 1), hodgkin lymphoma (n = 12), or leukemia (n = 6) were included (median time between diagnosis and study inclusion was 44 month). The primary endpoint was met, with an improvement of 20 points in HEI-EPIC score in 52.2 % (n = 12) of AYAs. At baseline, median HEI-EPIC score was 47.0 points (range from 40.0 to 55.0 points) and a good, moderate and bad nutritional intake was seen in 4.3, 73.9 and 21.7 % of AYAs. At week 12, median HEI-EPIC improved significantly to 65.0 points (range from 55.0 to 76.0 points) (p ≤ 0.001) and a good, moderate and bad nutritional intake was seen in 47.8, 52.2 and 0 % of AYAs. No change was seen in quality of life, waist-hip ratio and blood pressure. Intensified nutrition counseling is feasible and seem to improve nutritional behavior of AYAs. Further studies will be required to demonstrate long-term sustainability and confirm the results in a randomized design in larger cohorts. Clinical trial identifier

    The aim of this paper is to highlight the significance of integrated governance in bringing about community participation, improved service delivery, accountability of public systems and human resource rationalisation. It discusses the strategies of innovative institutional structures in translating such integration in the areas of public health and nutrition for poor communities. The paper draws on experience of initiating integrated governance through innovations in health and nutrition programming in the resource-poor state of Chhattisgarh, India, at different levels of governance structures--hamlets, villages, clusters, blocks, districts and at the state. The study uses mixed methods--i.e. document analysis, interviews, discussions and quantitative data from facilities surveys--to present a case study analyzing the process and outcome of integration. The data indicate that integrated governance initiatives improved convergence between health and nutrition departments of the state at all levels. Also, innovative structures are important to implement the idea of integration, especially in contexts that do not have historical experience of such partnerships. Integration also contributed towards improved participation of communities in self-governance, community monitoring of government programs, and therefore, better services. As governments across the world, especially in developing countries, struggle towards achieving better governance, integration can serve as a desirable process to address this. Integration can affect the decentralisation of power, inclusion, efficiency, accountability and improved service quality in government programs. The institutional structures detailed in this paper can provide models for replication in other similar contexts for translating and sustaining the idea of integrated governance. This paper is one of the few to investigate innovative public institutions of a and community mobilisation to explore this important, and under

    Rattray, Megan; Desbrow, Ben; Roberts, Shelley

    Nutrition is an important part of recovery for hospitalized patients. The aim of this study was to assess the nutritional adequacy of meals provided to and consumed by patients prescribed a therapeutic diet. Patients (N = 110) prescribed a therapeutic diet (texture-modified, low-fiber, oral fluid, or food allergy or intolerance diets) for medical or nutritional reasons were recruited from six wards of a tertiary hospital. Complete (24-h) dietary provisions and intakes were directly observed and analyzed for energy (kJ) and protein (g) content. A chart audit gathered demographic, clinical, and nutrition-related information to calculate each patient's disease-specific estimated energy and protein requirements. Provisions and intake were considered adequate if they met ≥75% of the patient's estimated requirements. Mean energy and protein provided to patients (5844 ± 2319 kJ, 53 ± 30 g) were significantly lower than their mean estimated requirements (8786 ± 1641 kJ, 86 ± 18 g). Consequently, mean nutrition intake (4088 ± 2423 kJ, 37 ± 28 g) were significantly lower than estimated requirements. Only 37% (41) of patients were provided with and 18% (20) consumed adequate nutrition to meet their estimated requirements. No therapeutic diet provided adequate food to meet the energy and protein requirements of all recipients. Patients on oral fluid diets had the highest estimated requirements (9497 ± 1455 kJ, 93 ± 16 g) and the lowest nutrient provision (3497 ± 1388 kJ, 25 ± 19 g) and intake (2156 ± 1394 kJ, 14 ± 14 g). Hospitalized patients prescribed therapeutic diets (particularly fluid-only diets) are at risk for malnutrition. Further research is required to determine the most effective strategies to improve nutritional provision and intake among patients prescribed therapeutic diets. Copyright © 2017 Elsevier Inc.

    The majority of Ugandan children face vulnerability and malnutrition. As a State Party to international human rights treaties, Uganda has legal obligations of guaranteeing the fundamental rights and the best interest of the nation's children. Despite being protected under international and national law, Uganda is not providing adequate child protection, including safeguarding children's food security. Numerous privately owned and unregulated children's homes face this problem. The overall aim of the study was to examine to what extent children's homes' operations are consistent with the right to adequate food, nutritional health and wellbeing of children. We performed a qualitative role- and capacity analysis of duty bearers with human rights duties towards children living in children's homes. We studied three groups of duty bearers: caretakers working in private children's homes, State actors working in government and its institutions, and non-State actors working in civil society organizations. A human rights based approach guided all aspects of the study. An analysis of the roles, performance and capacities of duty bearers was employed, with individual face-to-face structured qualitative in-depth interviews, self-administered structured questionnaires, and a structured observational study, as well as a desk review of relevant literature. The State of Uganda's efforts to respect and realize its obligations towards children living in children's homes is inadequate. There are numerous capacity gaps among the duty bearers, and the concepts of human rights and the best interest of the child are not well understood among the duty bearers. The efforts of the State of Uganda to realize its human rights obligations towards children in children's homes are lacking in important areas. Hence the State does not fulfill its minimum obligations under the International Covenant on Economic, Social and Cultural Rights to ensure all children freedom from hunger. There is a need

A prospective study was conducted. Twenty-six severe malnutrition patients with anorexia nervosa, body mass index (BMI) ≤ 16 kg/m 2 admitted to intensive care unit (ICU) of Peking University Third Hospital and general three ward of Peking University Sixth Hospital from June 1st to September 30th, 2017 were enrolled. The extracellular water (ECW), intracellular water (ICW), ECW/ICW ratio, adipose tissue mass (ATM), lean tissue mass (LTM), total body water/body weight (TBW/WT), ATM/WT, and LTM/WT were measured by multi-frequency bioelectrical impedance meter. Thirty-eighty healthy volunteers with normal nutritional status (23.0 kg/m 2 > BMI > 18.5 kg/m 2 ) matched by gender and height were enrolled as healthy control group. The predictive value of main body composition for nutritional status were analyzed by receiver operating characteristic (ROC) curve. All the patients were female. There was no significant difference in height between two groups, but WT and BMI in the severe malnutrition group were significantly higher than those in the healthy control group [WT (kg): 38.1±4.9 vs. 54.2±3.3, BMI (kg/m 2 ): 13.6±2.5 vs. 21.2±1.1, both P anorexia nervosa changed significantly.

    Full Text Available We have demonstrated that undergraduate and high school students share two contradictory concep- tions  regarding  the  energy  yielding  metabolism  (EYM:  the  incorrect  notion  that only glucose can be used for ATP  production together  with  more appropriated conception  according  to which other molecules,  mainly  lipids can also be used for ATP  production.  We have  deepened  the  study  about the origin of such conceptual  profile. Using questionnaires, we have determined that 7th grade school students do not  present  the  erroneous  conception,  but those  from the 8th  grade  (and  later  grades do.  This  finding has led us to  propose  the  hypothesis  that the wrong conception  may  emerge as a result of formal learning during 8th grade.  Indeed, the analysis of 8th grade textbooks  showed that the carbohydrates were associated  mainly  with  energy production by the  cells, while proteins  and  lipids were regarded  only as structural and storage  molecules, respectively.  In addition, only the glycolytic pathway was taught in high school, reinforcing  the  misconception.   We have also demonstrated that the conceptual  profile was widely distributed among students from different schools of different regions of the Rio de Janeiro  state,  reinforcing the importance of reformulation of the teaching of EYM-related topics  both  in grade  and  high schools.  Here we describe  the  development and  the  evaluation of an investigation-based approach  to human  nutrition to be used with  8th grade  students.  This  method- ology is based  in the  use of the  nutritional tables  found  in Brazilian  food packages  and  allows the students to identify not only which of the main nutrients do contain  calories (and thus can be used for,, energy production,, but the amount of calories found in 1g of each of them.  The methodology wastested

    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.

    Full Text Available The use of colloidal silver as an antibiotic was becoming widespread until the 1940s. However, with the discovery of antibiotics, usage of colloidal silver had been reduced because of being expensive. The fact that bacteria develop resistance to antibiotics lead to prohibiton the usage of antibiotics in poultry diets as growth promoters. Based on these developments reuse of colloidal silver has been raised as an alternative to antibiotics. Without prejudice to the beneficial enzymes, colloidal silver disables certain enzymes needed by bacteria, viruses, yeasts, and fungus resulting in the destruction of these enzymes. It is reported that increase in surface area of nano-particles of silver increase antibacterial activity. The most important limitation on the widespread use of silver nanoparticles as feed additives is uncertainty about the possible toxic effects. In this review, studies for the use of colloidal silver particles in poultry feed were evaluated and tried to seek answer the question “may be a new resource that can be used as an alternative to antibiotics?

    Do gene-gene and gene-environment interactions in folate-homocysteine (Hcy) pathway have a predisposing role for Down syndrome (DS)? The study provides evidence that in addition to advanced age, maternal genotype, micronutrient deficiency and elevated Hcy levels, individually and in combination, are risk factors for Down syndrome. Polymorphisms in certain folate-Hcy-pathway genes (especially the T allele of MTHFR C677T), elevated Hcy and poor folate levels in mothers during pregnancy have been shown to be risk factors for Down syndrome in certain Asian populations (including the eastern region of India), while the same SNPs are not a risk factor in European populations. This conflicting situation alludes to differential gene-environment (nutrition) interactions in different populations which needs to be explored. Between 2008 and 2012, 151 Down syndrome triads and 200 age-matched controls (Control mothers n = 186) were included in the study. Seven polymorphisms in six genes of folate-Hcy metabolic pathway, along with Hcy, cysteine (Cys), vitamin B12 (vit-B12) and folate levels, were analysed and compared among the case and control groups. Genotyping was performed by the PCR-RFLP technique. Levels of homocysteine and cysteine were measured by HPLC while vitamin B12 and folate were estimated by chemiluminescence. We demonstrate that polymorphisms in the folate-Hcy pathway genes in mothers collectively constitute a genotypic risk for DS which is effectively modified by interactions among genes and by the environment affecting folate, Hcy and vitamin B12 levels. The study also supports the idea that these maternal risk factors provide an adaptive advantage during pregnancy supporting live birth of the DS child. Our inability to obtain genotype and nutritional assessments of unaffected siblings of the DS children was an important limitation of the study. Also, its confinement to a specific geographic region (the eastern part) of India, and relatively small sample size

    Previous research has reported the existence of disordered eating in students studying nutrition and dietetics. However, the occurrence of exercise addiction, previously linked to disordered eating, is poorly understood in this group. The main objective of this study was to explore the prevalence of self-reported symptoms of exercise addiction and the association with disordered eating in a sample of students studying nutrition and dietetics. A secondary objective was to compare the prevalence of exercise addiction to students enrolled in another health-related degree. We conducted a cross-sectional study in 165 undergraduate students. Participants were students of both sexes enrolled in nutrition and dietetics and occupational therapy degree programs at an Australian university in August 2013. Participants completed four validated questionnaires for assessment of exercise- and eating-related attitudes and behaviors measuring scores for exercise addiction, weekly volume of physical activity (PA), eating disorder symptoms, and cognitive restraint. Stretch stature and body mass were measured and body composition was assessed using dual energy x-ray absorptiometry. Independent t test, Mann-Whitney U test, and χ 2 test were completed to compare groups of students based on sex, degree, or eating attitudes. Spearman's correlation was performed to explore associations between continuous variables (exercise addiction scores, PA volume, and scores for eating attitudes and cognitive restraint). Approximately 23% of nutrition and dietetics students were found to be at risk of exercise addiction (20% females and 35% males; P=0.205), while the majority demonstrated some symptoms of exercise addiction. A similar proportion of at risk individuals was found in the female occupational therapy group (19%; P=1.000). In females (nutrition and dietetics and occupational therapy combined), the exercise addiction scores were associated with three other outcome measures: PA volume (r s

    Spaceflight impacts human physiology, including well documented immune system dysregulation. Diet, immune function, and the microbiome are interlinked, but diet is the only one of these factors that we have the ability to easily, and significantly, alter on Earth or during flight. As we understand dietary impacts on physiology more thoroughly, we may then improve the spaceflight diet to improve crew health and potentially reduce spaceflight-associated physiological alterations. It is expected that increasing the consumption of fruits and vegetables and bioactive compounds (e.g., omega-3 fatty acids, lycopene, flavonoids) and therefore enhancing overall nutritional intake from the nominal shelf-stable, fully-processed space food system could serve as a countermeasure to improve human immunological profiles, the taxonomic profile of the gut microbiota, and nutritional status, especially where currently dysregulated during spaceflight. This interdisciplinary study will determine the effect of the current shelf-stable spaceflight diet compared to an "enhanced" shelf-stable spaceflight diet (25% more foods rich in omega-3 fatty acids, lycopene, flavonoids, and more fruits, and vegetables in general). The NASA Human Exploration Research Analog (HERA) 2017 missions, consisting of four 45-day missions with closed chamber confinement and realistic mission simulation in a high-fidelity mock space vehicle, will serve as a platform to replicate mission stressors and the effects on crew biochemistry, immunology, and the gut microbiome. Bio sampling of crewmembers is scheduled for selected intervals pre- and in-mission. Data collection also includes dietary intake recording. Outcome measures will include immune markers (e.g., peripheral leukocyte distribution, inflammatory cytokine profiles, T cell function), the taxonomic and metatranscriptomic profile of the gut microbiome, and nutritional status biomarkers and metabolites. Statistical evaluations will determine physiological

    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.

    Full Text Available Introduction: - Menopause is a universal reproductive phenomenon. All the nutrients plays important role at the time of menopause and in prevention of diseases. Deficiency of vitamin D is one of the major contributory factors responsible for lower bone mineral density (BMD in menopausal women. Iron deficiency anemia is common among menopausal women. The present study was conducted to assess the views on importance of nutrition & intake of various food items during menopause. Methods: - Community based   cross sectional study. A total of 100 women aged 45-55 years in post-menopausal phase were selected from urban areas of district Varanasi during 2012-13. Data were collected by pretested questionnaire cum interview method. Results: - In the present study half of respondent belonged to 40-45 years age group. When they were asked about importance of nutrition during menopause 70% respondent said that they paid attention on their diet during menopause. 79% women preferred food being cooked in their kitchen. 69% women took milk in their regular diet. 95% women’s took fruits and vegetables in their diet. Only 76% have knowledge of added requirement of iron & calcium but only 59% women had iron and calcium reach foods in their regular diet. Conclusion: - In the present study about three fourth respondents knew about nutritional importance during menopause.

    To explore the barriers for nutritional care as perceived by nursing staff at an acute orthopaedic ward, aiming to implement evidence-based nutritional care. Previous studies indicate that nurses recognise nutritional care as important, but interventions are often lacking. These studies show that a range of barriers influence the attempt to optimise nutritional care. Before the implementation of evidence-based nutritional care, we examined barriers for nutritional care among the nursing staff. Qualitative study. Four focus groups with thirteen members of the nursing staff were interviewed between October 2013-June 2014. The interview guide was designed according to the Theoretical Domains Framework. The interviews were analysed using qualitative content analysis. Three main categories emerged: lacking common practice, failing to initiate treatment and struggling with existing resources. The nursing staff was lacking both knowledge and common practice regarding nutritional care. They felt they protected patient autonomy by accepting patient's reluctance to eat or getting a feeding tube. The lack of nutritional focus from doctors decreased the nursing staffs focus leading to nonoptimal nutritional treatment. Competing priorities, physical setting and limited nutritional supplements were believed to hinder nutritional care. The results suggest that nutritional care is in a transitional state from experience- to evidence-based practice. Barriers for nutritional care are grounded in lack of knowledge among nursing staff and insufficient collaboration between nursing staff and the doctors. There is a need for nutritional education for the nursing staff and better support from the organisation to help nursing staff provide evidence-based nutritional care. This study contributes with valuable knowledge before the implementation of evidence-based nutritional care. The study provides an understanding of barriers for nutritional care and presents explanations to why

    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

    This Co-ordinated Research Programme (CRP) was formally established by the Agency in October 1988, and has since then expanded to encompass 13 participants in 13 countries. Its general objective is to help establish competence in the use of stable isotope techniques, particularly in developing countries, and particularly with reference to applications of 2 H, 13 C, 15 N, and 18 O. This report summarizes the discussions that took place during the first Research Co-ordination Meeting (RCM). Working papers (progress reports) presented by the participants are included as annexes together with a preliminary report on the results of a series of intercomparison exercises involving enriched stable isotope reference materials containing 2 H, 13 C, 15 N and 18 O. For the future it was agreed that more work needs to be done to harmonize the analytical techniques being used, and to obtain support for new CRPs relating to human energy expenditure studies in pregnancy, lactation, growth and other conditions, and to studies of nitrogen turnover in relation to malnutrition and liver function.

    Poor vitamin D status has been reported to be highly prevalent in many non-western immigrant groups living in Norway and other western countries. However, data on rickets are scarce, and the aim of the current study was to identify new cases of nutritional rickets in Norway in the period 2008-2012 among children under the age of 5 years. Register-based cohort study. The Norwegian population from 2008 to 2012. Children with nutritional rickets under the age of 5 years. Nutritional rickets. Patients with ICD10 (International Statistical Classification of Diseases and Related Health Problems, 10th revision) diagnosis code E55.0 (active rickets) treated at all Norwegian hospitals were identified in the Norwegian Patient Registry. We were able to review 85% of the medical records for diagnosis confirmation. In addition, we identified patients with the diagnoses E55.9, E64.3 and E83.3 to identify individuals with rickets who had been given other diagnoses. Nutritional rickets was confirmed in 39 children aged 0-4 years with the diagnosis of E55.0. In addition, three patients with the diagnosis of unspecified vitamin D deficiency (E55.9) were classified as having nutritional rickets, giving a total of 42 patients. Mean age at diagnosis was 1.40 years (range 0.1-3.5 years), and 93% had a non-western immigrant background. The incidence rate of rickets was estimated to be 0.3 per 10 000 person-years in the total Norwegian child population under the age of 5 years and 3.1 per 10 000 person-years in those with an immigrant background from Asia or Africa. The number of children with nutritional rickets in Norway remained low in the period 2008-2012. Nearly all children had a non-western immigrant background. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017. All rights reserved.

    Full Text Available INTRODUCTION : Changes in nutritional status, such as weight loss and malnutrition, are a very common complication in patients with chronic obstructive pulmonary disease (COPD.These changes primarily affect the patients' quality of life and functional capacity and they are also independent prognostic indicators of both morbidity and mortality. The above information inspired us to evaluate the nutritional status in these patients by measuring daily oral intake and anthropom etric measures. METHOD : This cross - sectional study was conducted during the period October 2008 to April 2009. Seventy two COPD patients in the age group of 40 - 65 years, with an FEV (1 < 65% of predicted and an FEV (1/FVC ratio < 70% were included in the study. All the patients were assessed for anthropometric parameters such as height, body weight (BW, Body Mass Index (BMI, Hip Circumference, waist circumference and mid upper arm circumference (MUAC. Daily dietary intakes were calculated by 24 hour re call method with the help of cups, spoons, and glasses which were standardized with commonly consumed recipes. Standardized models of chapatti, rice, fruits, and snacks items were used for accurate data. Energy and nutrient intakes were derived using the N utritive value of Indian foods. RESULTS : The prevalence of under nutrition were (30/72 41.6% based on body mass index (<18.5 kg/m(2 and (46/72 63.8% based on mid - upper arm circumference (<24 cm.More number of patients was above 60 years of age in the income grouping 3000 - 5000 INR / month living with family members of more than 3 per house. The daily intake of food as compared to reference RDA is as follows energy 54.51%, carbohydrates 84.85%, protein60.52% and Fats 71.2%. CONCLUSION : The prevalence of u nder nutrition were (30/72 41.6% based on body mass index (<18.5 kg/m2 and (46/72 63.8% based on mid - upper arm circumference (<24 cm .

  9. Palaeoproteomics for human evolution studies

    The commonplace sequencing of Neanderthal, Denisovan and ancient modern human DNA continues to revolutionize our understanding of hominin phylogeny and interaction(s). The challenge with older fossils is that the progressive fragmentation of DNA even under optimal conditions, a function of time and temperature, results in ever shorter fragments of DNA. This process continues until no DNA can be sequenced or reliably aligned. Ancient proteins ultimately suffer a similar fate, but are a potential alternative source of biomolecular sequence data to investigate hominin phylogeny given their slower rate of fragmentation. In addition, ancient proteins have been proposed to potentially provide insights into in vivo biological processes and can be used to provide additional ecological information through large scale ZooMS (Zooarchaeology by Mass Spectrometry) screening of unidentifiable bone fragments. However, as initially with ancient DNA, most ancient protein research has focused on Late Pleistocene or Holocene samples from Europe. In addition, only a limited number of studies on hominin remains have been published. Here, an updated review on ancient protein analysis in human evolutionary contexts is given, including the identification of specific knowledge gaps and existing analytical limits, as well as potential avenues to overcome these.

    A major problem occurring in cross-sectional studies is sampling bias. Length of hospital stay (LOS) differs strongly between patients and causes a length bias as patients with longer LOS are more likely to be included and are therefore overrepresented in this type of study. To adjust for the length bias higher weights are allocated to patients with shorter LOS. We determined the effect of length-bias adjustment in two independent populations. Length-bias correction is applied to the data of the nutritionDay project, a one-day multinational cross-sectional audit capturing data on disease and nutrition of patients admitted to hospital wards with right-censoring after 30 days follow-up. We applied the weighting method for estimating the distribution function of patient baseline variables based on the method of non-parametric maximum likelihood. Results are validated using data from all patients admitted to the General Hospital of Vienna between 2005 and 2009, where the distribution of LOS can be assumed to be known. Additionally, a simplified calculation scheme for estimating the adjusted distribution function of LOS is demonstrated on a small patient example. The crude median (lower quartile; upper quartile) LOS in the cross-sectional sample was 14 (8; 24) and decreased to 7 (4; 12) when adjusted. Hence, adjustment for length bias in cross-sectional studies is essential to get appropriate estimates. Copyright © 2015 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

    We have previously shown that irregular lifestyle of young Japanese female students are significantly related to their desire to be thinner. In the present study, we examined the nutritional knowledge and food habits of Chinese university students and compared them with those of other Asian populations. A self-reported questionnaire was administered to 540 students, ranging in age from 19-24 years. Medical students from Beijing University (135 men and 150 women) in Northern China and Kunming Medical College in southern China (95 men and 160 women) participated in this study. The parametric variables were analyzed using the Student's t-test. Chi-square analyses were conducted for non-parametric variables. Our results showed that 80.5% of students had a normal BMI and 16.6 % of students were underweight with the prevalence of BMI>30 obesity being very low in this study sample. Young Chinese female students had a greater desire to be thinner (62.0%) than males (47.4%). Habits involving regular eating patterns and vegetable intake were reported and represent practices that ought to be encouraged. The university and college arenas represent the final opportunity for the health and nutritional education of a large number of students from the educator's perspective. Our findings suggest the need for strategies designed to improve competence in the area of nutrition.

    The use of nutritional supplements (NS) places athletes at great risk for inadvertent doping. Due to the paucity of data on supplement use, this study aimed to determine the proportion of Ugandan athletes using nutritional supplements and to investigate the athletes' motivation to use these supplements. A cross-sectional study was conducted in which an interviewer-administered questionnaire was used to collect data from 359 professional athletes participating in individual (boxing, cycling, athletics) and team (basketball, rugby, football, netball, and volleyball) sports. The data were categorized, and a Chi-square test was used for statistical analysis. Of the 359 athletes, 48 (13.4%) used nutritional supplements. Carbohydrate supplements, energy drinks, vitamin and mineral supplements, fish oils, and protein supplements were the most common supplements used by athletes. NS use was significantly more common among athletes who played rugby and basketball ( X 2 = 61.101, p sport for 5-10 years ( X 2 = 7.460, p = 0.024), and athletes who had attained a tertiary education ( X 2 = 33.377, p performance and health. Compared to NS use by athletes elsewhere, NS use among Ugandan athletes was low. However, determinants of athlete NS use in the current study (category of sport and duration of time spent playing the sport) are similar to those reported elsewhere.

    Fast growing epidemic of chronic diseases causes many health challenges over the world. Regarding reported pros and cons, the aim of the current study is to review the effect of nutrition and physical educational intervention in decreasing cardiovascular risk factors. In this review study, searching has done through the English and Persian databases. Articles with other languages, lack of important information, and score 3 or less in the JADAD standard checklist were exluded from the study. In the primary search, 194 articles have been found.Through four stages of secondary search and further evaluation, 43 articles were selected. These articles were published between 1989 to 2013. According to these findings, the majority of articles showed a positive effect of nutrition and physical activity educational interventions on cardiovascular risk factors- blood cholesterol, systolic and diastolic blood pressure, as well as smoking cigarette in high risk patients. These results, suggest the necessity of continiuting nutrition and physical educational intervention for individuals with cardiovascular risk factors.

    Full Text Available Abstract Background The study exploits a natural human experimental model of subsistence farmers experiencing chronic and seasonally modified food shortages and infectious burden. Two seasons existed, one of increased deprivation and infections (Jul-Dec, another of abundance and low infections (Jan-Jun; referred to as the hungry/high infection and harvest/low infection seasons respectively. Prior analysis showed a 10-fold excess in infectious disease associated mortality in young adults born in the hungry/high infection versus harvest/low infection season, and reduced thymic output and T cell counts in infancy. Here we report findings on the role of early life stressors as contributors to the onset of T cell immunological defects in later life. Methods We hypothesised that season of birth effects on thymic function and T cell immunity would be detectable in young adults since Kaplan-Meier survival curves indicated this to be the time of greatest mortality divergence. T cell subset analyses by flow-cytometry, sjTRECs, TCRVβ repertoire and telomere length by PCR, were performed on samples from 60 males (18-23 y selected to represent births in the hungry/high infection and harvest/low infection Results Total lymphocyte counts were normal and did not differ by birth season. CD3+ and CD4+ but not CD8+ counts were lower for those born during the hungry/high infection season. CD8+ telomere length also tended to be shorter. Overall, CD8+ TCRVβ repertoire skewing was observed with 'public' expressions and deletions seen in TCRVβ12/22 and TCRVβ24, respectively but no apparent effect of birth season. Conclusions We conclude that, although thymic function was unchanged, the CD4+ and CD3+ counts, and CD8+ telomere length results suggested that aspects of adult T cell immunity were under the influence of early life stressors. The endemicity of CMV and HBV suggested that chronic infections may modulate immunity through T cell repertoire development. The

    Somatic cell cloning technology in mammals promotes the multiplication of productively-valuable genetically engineered individuals, and consequently allows also for standardization of transgenic farm animal-derived products, which, in the context of market requirements, will have growing significance. Gene farming is one of the most promising areas in modern biotechnology. The use of live bioreactors for the expression of human genes in the lactating mammary gland of transgenic animals seems to be the most cost-effective method for the production/processing of valuable recombinant therapeutic proteins. Among the transgenic farm livestock species used so far, cattle, goats, sheep, pigs and rabbits are useful candidates for the expression of tens to hundreds of grams of genetically-engineered proteins or xenogeneic biopreparations in the milk. At the beginning of the new millennium, a revolution in the treatment of disease is taking shape due to the emergence of new therapies based on recombinant human proteins. The ever-growing demand for such pharmaceutical or nutriceutical proteins is an important driving force for the development of safe and large-scale production platforms. The aim of this paper is to present an overall survey of the state of the art in investigations which provide the current knowledge for deciphering the possibilities of practical application of the transgenic mammalian species generated by somatic cell cloning in biomedicine, the biopharmaceutical industry, human nutrition/dietetics and agriculture.

    Full Text Available Abstract Background Malnutrition and intestinal parasitic infections are common among children in Burkina Faso and Nepal. However, specific health-related data in school-aged children in these two countries are scarce. In the frame of a larger multi-stakeholder project entitled “Vegetables go to School: Improving Nutrition through Agricultural Diversification” (VgtS, a study has been designed with the objectives to: (i describe schoolchildren’s health status in Burkina Faso and Nepal; and to (ii provide an evidence-base for programme decisions on the relevance of complementary school garden, nutrition, water, sanitation and hygiene (WASH interventions. Methods/Design The studies will be conducted in the Centre Ouest and the Plateau Central regions of Burkina Faso and the Dolakha and Ramechhap districts of Nepal. Data will be collected and combined at the level of schools, children and their households. A range of indicators will be used to examine nutritional status, intestinal parasitic infections and WASH conditions in 24 schools among 1144 children aged 8–14 years at baseline and a 1-year follow-up. The studies are designed as cluster randomised trials and the schools will be assigned to two core study arms: (i the ‘complementary school garden, nutrition and WASH intervention’ arm; and the (ii ‘control’ arm with no interventions. Children will be subjected to parasitological examinations using stool and urine samples and to quality-controlled anthropometric and haemoglobin measurements. Drinking water will be assessed for contamination with coliform bacteria and faecal streptococci. A questionnaire survey on nutritional and health knowledge, attitudes and practices (KAP will be administered to children and their caregivers, also assessing socioeconomic, food-security and WASH conditions at household level.

    To evaluate the effects of structured triglycerides in parenteral nutrition versus a physical medium-chain triglycerides (MCT)/long-chain triglycerides (LCT) mixture on severe hemorrhagic shock patients after resuscitation. In a randomized trial, we studied 20 critical patients with a total blood loss of over 3000 ml perioperatively and/or intraoperatively. The use of triglycerides started from Day 3 postoperation and parenteral nutrition lasted for no less than 5 days. They were allocated to receive one of two nutrition regiments: structured triglycerides in Group A (n = 10) and MCT/LCT in Group B (n = 10). There were no significant differences of general conditions in two groups. Before the start of parenteral nutrition (d0), d1 d3 and d5 after start of infusion, the following parameters were measured: hemoglobin (Hb), platelet count (Plt), alanine aminotransferase (ALT), total bilirubin (TB), direct bilirubin (DB), serum triglycerides (TG), prealbumin (PA) and transferrin (TF). And mean artery pressure (MAP), heart rate (HR) and central vein pressure (CVP) were also recorded at the same time-points. Then the post-TG changes of the above data were compared in both groups. After the use of triglycerides, there were no significant differences of MAP, HR, CVP, Hb and Plt in both groups (P > 0.05). At D3 and D5, the serum levels of TG ((2.1 ± 0.4) vs (1.6 ± 0.6) mg/L, (2.3 ± 0.7) vs (1.5 ± 0.3) mg/L) and alanine aminotransferase ((133 ± 58) vs (97 ± 26) U/L; (116 ± 48) vs (77 ± 31) U/L) were significantly higher in Group B versus those receiving structured triglycerides in Group A (P 0.05). The serum levels of such nutrition markers as PA ((195 ± 55) vs (166 ± 55) mg/L,(245 ± 53) vs (195 ± 58) mg/L) and TF ((2.6 ± 0.5) vs (2.5 ± 0.6) g/L, (3.3 ± 0.8) vs (2.9 ± 0.6) g/L)were significantly higher in Group A than those in Group B (P synthesis and hepatocyte protection, structured triglycerides in parenteral nutrition is advantageous to standard MCT

    The effects of different cooking methods (boiling, grilling, frying and microwave roasting) on the nutritional quality of chicken meat were assessed by measuring quality parameters i.e. moisture, ash, protein, fat and fiber contents. The fatty acid composition of chicken fat was analyzed by GC-FID. The chicken fat was found to contain high levels of oleic acid (38.0-47.3%) followed by linolenic acid (13.3-28.0%) and palmitic acid (2.0-13.6%). Different cooking methods exhibited significant effect (p<=0.05) on the fatty acid composition and other nutritional parameters of meat samples. Generally, fried meat had lower saturated fatty acid contents. It can be concluded from this study that boiling and frying are healthy cooking practices while grilling and microwave roasting show some negative effects. (author)

    Full Text Available Food security and nutritional security are the subsets of livelihood security. Poor nutritional outcomes of infants and children arise from the poor health status of women, overall poverty, lack of hygiene and inadequate health facilities. The study discusses the divergence between food security and nutritional security in the state as a whole and the region in particular.A multi stage random sampling technique has been adopted for the collection of data.Statistical analysis used for drawing valid inferences are testing of hypothesis, chi square test, regression analysis and fitting of trend lines. In the present study an attempt has been made to address the issues namely: i incidence of malnutrition and food insecurity through three critical links viz. children, adolescent girls and women, ii surplus/deficit of production of cereals, pulses, food grains and oilseeds as per requirement iii trends of production and availability of secondary diets such as egg, meat, fish and milk iv indicators of malnutrition. Production must be diversified from cereal crop production like paddy to other crops.A life-cycle approach to management was adopted that integrates strategy, people resources, processes and measurements to improve.

    Full Text Available 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.

    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.

    Full Text Available 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

    Full Text Available The objective was to identify the main factors influencing micronutrient policies in the opinion of policy actors in ten European countries. Study was carried out during Jan-Nov 2010 in European countries: the Czech Republic, Denmark, England, Germany, Greece, Italy, the Netherlands, Norway, Poland and Spain. Semi-structured qualitative interviews were conducted with representatives of stakeholders involved in the vitamin D, folate and iodine policy making process. Fifty eight key informants representing mainly scientific advisory bodies (n=24 and governmental organisations (n=19 participated in the study. The remaining interviewees represented non-governmental organisations (n=6, industry (n=4 or were independent academic or health professional experts (n=5. Data were analysed by theoretical interpretative thematic analysis. Insights from interviewees on the development of micronutrient policies were grouped using the Public Health Nutrition Policy-making model. The main factors influencing the micronutrient policies were: systematic monitoring of nutrition and health, causal relationships between consumers’ diet-related behaviours and health outcomes, scientific recommendations from national bodies (Science area; scientific recommendations from international authorities and experiences of other countries, EU legislation, cultural factors (Wider context and political environment, national capacity to deal with the problem, national legislation, economics, stakeholder engagement, relationships between stakeholders (Policy and institutions area. The spectrum and weight of the factors influencing nutritional policy depends on nutrient, country and degree of its “advanced status” within nutrition policy, political environment, culture and socio-economic conditions as well as the point of view (who is expressing the opinion.

    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. Copyright © 2014 Elsevier Ltd. All rights reserved.

    To categorize the research topics covered by a sample of randomized controlled trials (RCT) included in systematic reviews of nutrition interventions to address obesity; to describe their funding sources; and to explore the association between funding sources and nutrition research topics. Cross-sectional study. RCT included in Cochrane Reviews of nutrition interventions to address obesity and/or overweight. Two hundred and thirteen RCT from seventeen Cochrane Reviews were included. Funding source and authors' conflicts of interest were disclosed in 82·6 and 29·6 % of the studies, respectively. RCT were more likely to test an intervention to manipulate nutrients in the context of reduced energy intake (44·2 % of studies) than food-level (11·3 %) and dietary pattern-level (0·9 %) interventions. Most of the food industry-sponsored studies focused on interventions involving manipulations of specific nutrients (66·7 %). Only 33·1 % of the industry-funded studies addressed dietary behaviours compared with 66·9 % of the non-industry-funded ones (P=0·002). The level of food processing was poorly considered across all funding sources. The predominance of RCT examining nutrient-specific questions could limit the public health relevance of rigorous evidence available for systematic reviews and dietary guidelines.

    Probiotics in human milk are a very recent field of research, as the existence of the human milk microbiome was discovered only about a decade ago. Current research is focusing on bacterial diversity and the influence of the maternal environment as well as the mode of delivery on human milk microbiota, the pathways of bacterial transfer to milk ducts, possible benefits of specific bacterial strains for the treatment of mastitis in mothers, and disease prevention in children. Recent advances in the assessment of early host-microbe interactions suggest that early colonisation may have an impact on later health. This review article summarises a scientific workshop on probiotics in human milk and their implications for infant health as well as future perspectives for infant feeding.

    The human and earth microbiomes are among the most important biological agents in understanding and preventing disease. Technology is advancing at a fast pace and allowing for high-resolution analysis of the composition and function of our microbial partners across regions, space, and time. Bioinformaticists and biostatisticians are developing ever more elegant displays to understand the generated megadatasets. A virtual cyberinfrastructure of search engines to cross-reference the rapidly developing data is emerging in line with technologic advances. Nutrition science will reap the benefits of this new field, and its role in preserving the earth and the humans who inhabit it will become evidently clear. In this report we highlight some of the topics of an A.S.P.E.N.-sponsored symposium held during Clinical Nutrition Week in 2013 that address the importance of the human microbiome to human health and disease.

    The nutritional requirements for proteins have been estimated for various age groups. The current status of knowledge concerning the quantitative needs for specific indispensable amino acids was reviewed and it was concluded that, except for infants, current values for pre-school children, school age children and healthy adults are based on limited experimental data and/or on results from nitrogen balance determinations which are open to serious question regarding their nutritional significance. A review of 13 C-labelled tracer studies carried out in MIT laboratories was undertaken to demonstrate the applicability of stable nuclide tracer studies for purposes of determining the amino acid requirements of humans. 5 refs

  12. The value of flavonoids for the human nutrition: Short review and perspectives

    Directory of Open Access Journals (Sweden)

    Harald P. Hoensch

    2015-11-01

    Full Text Available Flavonoids are phytochemicals and belong to the polyphenols. A wide variety of beneficial factors has been attributed to their mode of action. Some of their activities concerns the inhibition of inflammatory pathways and the down regulation of genes involved in chronic inflammatory disease states. These genes enhance the inflammatory signaling pathways leading to expression of inflammatory cytokines and chemokines. Flavonoids from fruits, vegetable and tea compounds can block many proinflammatory proteins and thus function as natural inhibitors of inflammation. Instead of using nonsteroidal anti-inflammatory drugs natural inhibitors could possibly be used to suppress the intensity of the inflammation in the chronically inflamed mucosa in patients with chronic inflammatory bowel disease. Natural inhibitors like flavonoids are xenobiotics which are metabolized by the cytochrome P-450 enzymes and conjugating protective enzymes. Flavonoids can induce these protective enzymes by upregulation and thereby could act as protective metabolic barrier within the intestinal mucosa. The nutritional value of flavonoids is probably related to their anti-inflammatory activity and through this mechanism responsible for prevention of neoplasia. The evidence for their clinical efficacy as essential compounds is still preliminary at best and limited but suggestive.

    Full Text Available In the present, work chemical composition and nutritional value of aerial parts of Cassia occidentalis L. was studied. The aerial parts of C. occidentalis possess favorable physicochemical properties with good nutritional value, such as high energy value, crude fibers, and vitamin levels. The X-ray fluorescence spectrophotometry data revealed that the sample is rich in minerals, especially in Fe, Ca, K, and Mn. Further, minerals such as Mg, Zn, Cu, Na, P, and S are present in good amount and depicted the nutritional value of the selected material. The plant sample is rich in phytochemicals such as flavonoids, alkaloids, lignin, tannins, and phenols. The presence of phytochemical constituents was confirmed by gas chromatography–mass spectrometry profile and high-performance thin layer chromatography fingerprinting techniques. The findings stimulate the on-farm cultivation of C. occidentalis on a large scale to relieve the iron deficiency in local community, and it can be used as a dietary supplement to treat anemia.

    Nutrition clubs (NC) operate in community settings and provide members with nutrition education and meal replacements for weight management. NC are owned and operated by distributors of Herbalife products. There are over 6200 NC in the US, but there has been no independent assessment of the association of these NC with biomarkers of health. We conducted a cross-sectional pilot study to compare the health status of 100 NC members to 100 community-matched controls (CC) in the greater Boston area. Each CC was matched to a NC member for community of residence (zip code), age category, gender, BMI category, race/ethnicity, education level (category), and readiness to make health changes. Measures obtained included cardio-metabolic risk factors, body composition, markers of nutritional status, reported health status, dietary intake, physical activity, sleep and depression. Participants were predominantly female (64%) and Hispanic (73%). NC members had significantly lower fasting insulin (P Herbalife NC membership for themselves and their families. A higher percentage of NC members (86%) compared to CC (32%) reported being in much better or somewhat better health compared to a year ago (P Herbalife NC membership was positively associated with perceived health and measured cardiometabolic benefits. However, causality cannot be inferred from these findings.

    To provide, for the first time, the calculated nutritional composition of 32 composite dishes commonly consumed in Barbados to enable dietary intake to be calculated from a Quantitative Food Frequency Questionnaire developed specifically for this population to determine associations between diet and risk of prostate and breast cancer. Weighed recipes were collected in up to six different households for each of the 32 composite dishes. The average nutritional composition for these composite dishes was calculated using the US Department of Agriculture National Nutrient Database. One hundred and fifty-two weighed recipes were collected for 32 composite dishes: five were fish based, two were ground beef dishes, two were chicken based, two were offal based, two were lamb dishes, one was pork based, three were rice based, three were commonly consumed home-made drinks, and the remaining were miscellaneous items. A total of 152 weighed recipes were collected and we provide, for the first time, nutritional composition data for 32 commonly consumed food and drink items in Barbados. Such data are essential for assessing nutrient intake and determining associations between diet and prostate and breast cancer in the Barbados National Cancer Study.

    To assess the nutritional status of mentally disabled children in Turkey on the basis of anthropometric indicators and dietary intake. The sample of the study consisted of 77 mentally disabled children with ages between 10 and 18 years. The body mass index and body fat ratios of the children were calculated by measuring their body weight, height, and the skinfold thickness of their triceps and subscapular. Their three-day nutrition consumption was recorded in order to determine their nutrient intake. When the body weights of the children were evaluated according to their ages, 14.3% of the children were found to be thin. The shortness rate among the participants was 28.6%. The shortness ratio was found to increase with age and girls had a higher inclination for shortness than boys. The ratios of those with ≤5(th) percentile upper middle arm circumference were 32.7% in the 10-13 age group, and 36.0% in the 14-18 age group. The folic acid and calcium intakes of girls in the 10-13 age group, and the calcium intakes of boys in the 10-13 age group were under the suggested values. In the 14-18 age group the vit C and calcium intakes of girls and the calcium intakes of boys were under the recommended values. The prevalence of malnutrition is high among mentally disabled children. In order to raise their quality of life, mentally disabled children must be provided with sufficient nutritional support.

    Full Text Available CONTEXT: Malnutrition is frequently observed in inpatients with malignant diseases and may contribute to longer hospital stays. OBJECTIVE: To compare the nutritional status, lymphocyte count, hemoglobin values and length of hospital stay of patients with and without malignant diseases. METHODS: This comparative study assessed indicators of nutritional status, namely body mass index, recent weight loss, lymphocyte count, hemoglobin and length of hospital stay, of 928 surgical patients with and without malignant diseases (50.2% females and 49.8% males. The chi-square test was used to compare proportions and the Mann-Whitney test was used to compare continuous measurements between two groups. The significance level was set at 5%. RESULTS: Patients with malignant diseases had longer hospital stays (P<0.0001, furthermore, a higher percentage of patients with malignant diseases had body mass index <18.5 (P<0.0001 and experienced recent weight changes (P<0.0002. Lymphocyte count also differed statistically between the groups (P = 0.0131, which lower levels were identified among patients with malignant diseases. CONCLUSION: The lymphocyte count, hemoglobin values and weight loss are important findings of nutritional depletion in patients with malignant diseases.

    Information of the difference in quality between farmed and wild fish is central to better ensuring fish products produced in aquaculture meet regulatory and consumer requirements. Proximate composition, amino acid and fatty acid profiles, and toxic elements contents of farmed and wild Chanodichthys mongolicus were established and compared. Significantly higher crude protein content while lower moisture content in farmed fish compared to wild fish were observed ( Pacids (TAA), total essential amino acids (TEAA), total non-essential amino acids (TNEAA) and total delicious amino acids (TDAA) in farmed fish were all significantly higher than those in the wild equivalent ( Pacid profiles in both farmed and wild C. mongolicus were dominated by monounsaturated fatty acid (MUFA), with farmed fish contained much more MUFA content compared to wild counterpart ( Pacid (PUFA) including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) than farmed fish ( Pacid (C18:2n6) were the predominant PUFA in wild and farmed C. mongolicus, respectively. Moreover, farmed fish displayed an overall lower toxic element levels (As, Cd, Pb and Hg) in comparison with wild fish, and both were far lower than the established limit standard. In conclusion, our results suggest that the nutritional quality of farmed C. mongolicus was inferior to their wild counterpart with respect to fatty acids nutrition, and therefore further studies should focus on the improving C. mongolicus diet in order to enhance the overall nutritional composition.

    Successful recruitment and retention of participants into research studies is critical for optimising internal and external validity. Research into diet and lifestyle of young women is important due to the physiological transitions experienced at this life stage. 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. 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. 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. 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.

  1. Role of oxidative stress and antioxidants in daily nutrition and human health.

    Diet may be defined as a complex process that should involve a deeper comprehension of metabolism, energy balance, and the molecular pathways involved in cellular stress response and survival, gut microflora genetics, enzymatic polymorphism within the human population, and the role of plant-derived polyphenols in this context. Metabolic syndrome, encompassing pathologies with a relatively high morbidity, such as type 2 diabetes, obesity, and cardiovascular disease, is a bullet point of the big concern about how daily dietary habits should promote health and prevent metabolic impairments to prevent hospitalization and the need for health care. From a clinical point of view, very few papers deal with this concern, whereas most of the evidence reported focuses on in vitro and animal models, which study the activity of phytochemicals contained in the daily diet. A fundamental issue addressed by dietitians deals with the role exerted by redox-derived reactive species. Most plant polyphenols act as antioxidants, but recent evidence supports the idea that these compounds primarily activate a mild oxidative stress to elicit a positive, beneficial response from cells. How these compounds may act upon the detoxifying system exerting a scavenging role from reactive oxygen or nitrogen species is still a matter of debate; however, it can be argued that their role is even more complex than expected, acting as signaling molecules in the cross-talk mitochondria-endoplasmic reticulum and in enzymatic pathways involved in the energetic balance. In this relationship, a fundamental role is played by the brain-adipose tissue-gut axis. The aim of this review was to elucidate this topic and the state of art about the role of reactive species in cell signaling and the function of metabolism and survival to reappraise the role of plant-derived chemicals.

    Full Text Available In northeast Brazil, nutritional deficiency diseases and schistosomiasis mansoni overlap. An experimental model, wich reproduces the marasmatic clinical form of protein-energy malnutrition, was developed in this laboratory to study these interactions. Albino Swiss mice were fed with a food association ingested usually by human populations in northeast Brazil. This diet (Regional Basic Diet - RBD has negative effects on the growth, food intake and protein utilization in infected mice (acute phase of murine schistosomiasis. Nitrogen balance studies have also shown that infection with Schistosoma mansoni has apparently no effect on protein intestinal absorption in well nourished mice. However, the lowest absorption ratios have been detected among RBD - fed infected animals, suggesting that suprerimposed schistosome infection aggravated the nutritional status of the undernourished host. The serum proteins electrophoretic pattern, as far as albumins are concerned, is quite similar for non-infected undernourished and infected well-fed animals. So, the significance of albumins as a biochemical indicator of the nutritional status of human populations residing in endemic foci of Manson's schistosomiasis, is discussable.

    Pidan and salted duck eggs are of nutritional rich alternative duck egg products which are predominantly consumed in China, Thailand, South Korea and other Chinese migrated countries. Both eggs are rich in proteins, lipids, unsaturated fatty acids and minerals. A Pidan whole egg contains 13.1% of protein, 10.7% of fat, 2.25% of carbohydrate and 2.3% of ash, whereas the salted duck egg contains 14% of protein, 16.6% of fat, 4.1% of carbohydrate and 7.5% of ash. The fresh duck egg contains a range of 9.30-11.80% of protein, 11.40-13.52% of fat, 1.50-1.74% of sugar and 1.10-1.17% of ash. Proteins, lipids, and ash contents are found to be greatly enhanced during the pickling and salting process of pidan and salted duck eggs. However, the alkaline induced aggregation of pidan leads to degradation and subsequent generation of free peptides and amino acids. Very few amino acids are found to be lost during the pickling and storage. However, no such losses of amino acids are reported in salted duck eggs during the salting process of 14 d. Phospholipids and cholesterol contents are lower in pidan oil and salted duck egg yolk oil. Thus, the pidan and salted duck eggs are nutritionally rich alternatives of duck egg products which will benefit the human health during consumption.

    Maternal and child undernutrition have adverse consequences for pregnancy outcomes and child morbidity and mortality, and they are associated with low educational attainment, economic productivity as an adult, and human wellbeing. 'Nutrition-sensitive' agriculture programs could tackle the underlying causes of undernutrition. This study is a four-arm cluster randomised controlled trial in Odisha, India. Interventions are as follows: (1) an agricultural extension platform of women's groups viewing and discussing videos on nutrition-sensitive agriculture (NSA) practices, and follow-up visits to women at home to encourage the adoption of new practices shown in the videos; (2) women's groups viewing and discussing videos on NSA and nutrition-specific practices, with follow-up visits; and (3) women's groups viewing and discussing videos on NSA and nutrition-specific practices combined with a cycle of Participatory Learning and Action meetings, with follow-up visits. All arms, including the control, receive basic nutrition training from government community frontline workers. Primary outcomes, assessed at baseline and 32 months after the start of the interventions, are (1) percentage of children aged 6-23 months consuming ≥ 4 out of 7 food groups per day and (2) mean body mass index (BMI) (kg/m 2 ) of non-pregnant, non-postpartum (gave birth > 42 days ago) mothers or female primary caregivers of children aged 0-23 months. Secondary outcomes are percentage of mothers consuming ≥ 5 out of 10 food groups per day and percentage of children's weight-for-height z-score  70%) proportion of Scheduled Tribe or Scheduled Caste (disadvantaged) households. A process evaluation will assess the quality of implementation and mechanisms behind the intervention effects. A cost-consequence analysis will compare incremental costs and outcomes of the interventions. This trial will contribute evidence on the impacts of NSA extension through participatory, low-cost, video

    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.

    Studies have shown that computer-based training in eating and nutrition for hospital nursing staff increased the likelihood that patients at risk of undernutrition would receive nutritional interventions. This article seeks to provide understanding from the perspective of nursing staff of conceptually important areas for computer-based nutritional training, and their relative importance to nutritional care, following completion of the training. Group concept mapping, an integrated qualitative and quantitative methodology, was used to conceptualize important factors relating to the training experiences through four focus groups (n = 43), statement sorting (n = 38), and importance rating (n = 32), followed by multidimensional scaling and cluster analysis. Sorting of 38 statements yielded four clusters. These clusters (number of statements) were as follows: personal competence and development (10), practice close care development (10), patient safety (9), and awareness about the nutrition care process (9). First and second clusters represented "the learning organization," and third and fourth represented "quality improvement." These findings provide a conceptual basis for understanding the importance of training in eating and nutrition, which contributes to a learning organization and quality improvement, and can be linked to and facilitates person-centered nutritional care and patient safety.

    Through radiochemical analysis of voluntary tissue donations, the United States Transuranium and Uranium Registries are gaining improved understanding of the distribution and biokinetics of actinide elements in occupationally exposed persons. Evaluation of the first two whole body contributions to the Transuranium Registry revealed an inverse proportionality between actinide concentration and bone ash fraction. The analysis of a whole body with a documented 241 Am deposition indicated a significantly shorter half-time in liver and a greater fraction resident in the skeleton than predicted by existing models. Other studies of the Registries are designed to evaluate in vivo estimates of actinide deposition with those derived from postmortem tissue analysis, compare results of animal experiments with human data, and reviw histopathologic slides for tissue toxicity that might be attributable to exposure to uranium and the transuranic elements. The implications of these recent findings and other work of the Registries are discussed from the standpoint of their potential impact on biokinetic modeling, internal dose assessment, safety standards, and operational health physics practices

    Full Text Available Body image and eating disorders have emerged as an essential facet of bio-psychosocial well-being. Although considered less prevalent in Ghana than in the West, body image and eating disorders are issues of global concern. One hundred (100 female participants with a mean age of approximately 21 years were recruited after informed consent for this pilot study. Results showed a positive correlation between body image and eating disorders. In addition, there was no significant difference between the levels of university education on female body image and eating distortions in Ghana. These findings underscore the importance for more future studies in nutritional psychology and related clinical management.

    Full Text Available Abstract Background Cachexia is a common problem in patients (pts suffering from upper gastrointestinal cancer. In addition, most of these patients suffer from malabsorption and stenosis of the gastrointestinal tract due to their illness. Various methods of supplementary nutrition (enteral, parenteral are practised. In patients with advanced pancreatic cancer (APC, phase angle, determined by bio-electrical impedance analysis (BIA, seems to be a survival predictor. The positive influence of BIA determinate predictors by additional nutrition is currently under discussion. Methods To examine the impact of additional parenteral nutrition (APN we assessed outpatients suffering from APC and progressive cachexia. The assessment based on the BIA method. Assessment parameters were phase angle, ECM/BCM index (ratio of extracellular mass to body cell mass, and BMI (body mass index. Patients suffering from progressive weight loss in spite of additional enteral nutritional support were eligible for the study. Results Median treatment duration in 32 pts was 18 [8-35] weeks. Response evaluation showed a benefit in 27 pts (84% in at least one parameter. 14 pts (43.7% improved or stabilised in all three parameters. The median ECM/BCM index was 1.7 [1.11-3.14] at start of APN and improved down to 1.5 [1.12-3.36] during therapy. The median BMI increased from 19.7 [14.4-25.9] to 20.5 [15.4-25.0]. The median phase angle improved by 10% from 3.6 [2.3-5.1] to 3.9 [2.2-5.1]. Conclusions We demonstrated the positive impact of APN on the assessed parameters, first of all the phase angle, and we observed at least a temporary benefit or stabilisation of the nutritional status in the majority of the investigated patients. Based on these findings we are currently investigating the impact of APN on survival in a larger patient cohort. Trial registration ClinicalTrials.gov Identifier: NCT00919659

    Adequate nutrition is critical for maintenance of crew health during and after extended-duration space flight. The impact of weightlessness on human physiology is profound, with effects on many systems related to nutrition, including bone, muscle, hematology, fluid and electrolyte regulation. Additionally, we have much to learn regarding the impact of weightlessness on absorption, mtabolism , and excretion of nutrients, and this will ultimately determine the nutrient requirements for extended-duration space flight. Existing nutritional requirements for extended-duration space flight have been formulated based on limited flight research, and extrapolation from ground-based research. NASA's Nutritional Biochemistry Laboratory is charged with defining the nutritional requirements for space flight. This is accomplished through both operational and research projects. A nutritional status assessment program is included operationally for all International Space Station astronauts. This medical requirement includes biochemical and dietary assessments, and is completed before, during, and after the missions. This program will provide information about crew health and nutritional status, and will also provide assessments of countermeasure efficacy. Ongoing research projects include studies of calcium and bone metabolism, and iron absorption and metabolism. The calcium studies include measurements of endocrine regulation of calcium homeostasis, biochemical marker of bone metabolism, and tracer kinetic studies of calcium movement in the body. These calcium kinetic studies allow for estimation of intestinal absorption, urinary excretion, and perhaps most importantly - deposition and resorption of calcium from bone. The Calcium Kinetics experiment is currently being prepared for flight on the Space Shuttle in 2001, and potentially for subsequent Shuttle and International Space Station missions. The iron study is intended to assess whether iron absorption is down-regulated dUl1ng

    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.

    Full Text Available Background: Agricultural expansion is a leading driver of deforestation, yet malnutrition remains a significant cause of morbidity. Understanding trade-offs and synergies between forest protection and agricultural expansion, and how they vary between groups across time, could help guide socially equitable sustainable development. Forests have important roles in supporting dietary diversity and micronutrient intake, but limited empirical evidence links forests and broad nutritional outcomes. Our research explores the associations between key indicators of malnutrition and forest cover and deforestation, the mediating role of socioeconomic factors, and underlying temporal trends. Methods: In this observational study, we explored associations between nutritional outcomes (underweightness, stunting, wasting, and overweightness in children younger than 5 years and forest cover and loss gradients (in 10 km buffers around communities in 61 032 African households. These households were surveyed by the Demographic and Health Surveys (DHS Program from nine countries (Burkina Faso, Cameroon, Democratic Republic of the Congo, Ethiopia, Ghana, Guinea, Kenya, Lesotho, and Liberia between 2003 and 2014. DHS data were combined with spatially explicit data on forest cover and loss, climate, infrastructure, economy, and demography in a series of generalised linear mixed-effects models. Findings: In urban areas, children in communities surrounded by 1 SD higher forest cover had 10·8% (95% CI 3·0–18·0; p=0·0073 lower incidence of underweightness and 11·7% (1·9–20·6; p=0·0212 lower incidence of wasting than did children in areas with the mean amount of forest cover. In rural areas, the relationship was reversed, with 6·0% (1·6–10·6; p=0·0074 higher incidence of underweightness among children in areas of 1 SD higher forest cover than among children in areas with the mean amount of forest cover.

    2015-03-01

    To delineate the available sources of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) for human consumption and to determine if the available supply is capable of supplying the nutrient levels recommended by expert bodies. There are converging opinions among experts, professional organizations and health professionals that a recommendation for a daily individual consumption of 500 mg of EPA/DHA would provide health benefits, and this translates to an annual human consumption of 1.3 million metric tons. Current human consumption of EPA/DHA is estimated to be only a small fraction of this amount and many people may suffer from suboptimal health as a result of low intake. EPA and DHA originate in the phytoplankton and are made available in the human food chain mainly through fish and other seafood. The fish catch is not elastic and in fact has long since reached a plateau. Aquaculture has grown rapidly, but most of the fish oil produced is currently being used to support aquaculture feed and so this would appear to limit aquaculture growth - or at least the growth in availability of fish sources of EPA/DHA. Vegetable oil-derived alpha-linolenic acid, though relatively plentiful, is converted only at a trace level in humans to DHA and not very efficiently to EPA, and so cannot fill this gap. Microbial EPA/DHA production can in the future be increased, although this oil is likely to remain more expensive than fish oil. Plant sources of EPA and DHA have now been produced in the laboratory via transgenic means and will eventually clear regulatory hurdles for commercialization, but societal acceptance remains in question. The purpose of this review is to discuss the various sources of omega-3 fatty acids within the context of the potential world demand for these nutrients. In summary, it is concluded that fish and vegetable oil sources will not be adequate to meet future needs, but that algal oil and terrestrial plants modified genetically to produce EPA and DHA

    To assess the effects of a texture-modified food program for dysphagia on the nutritional, biochemical and functional profile in a cohort of institutionalised older people in Italy. Dysphagic institutionalised older people, often also affected by dementia, are frequently exposed to malnutrition. Malnutrition in older people has negative effects on mortality, days of hospitalisation, infection, wound healing and risk of pressure injuries. Therefore, it is very important to prevent malnutrition in this frail population. A pre-post study without a control group. The study included 479 dysphagic institutionalised older people from 20 nursing homes. Anthropometrical, biochemical, nutritional and functional parameters were collected retrospectively, 6 months before the study intervention, at time zero and, prospectively for 6 months after implementing the NUTRICARE food programme, for a total of nine evaluations. The NUTRICARE programme includes meals without nutritional supplementation, and personalised levels of density, viscosity, texture and particle size. The total mean body mass index of our sample passed from 17.88-19.00; body weight averagely improved by 7.19%, as well as their nutritional and biochemical profiles. There was a progressive improvement of total protein and serum albumin values. Nutritional parameters (serum transferrin and lymphocytes) displayed similar changes. Plasma lymphocytes reached normal levels in 98.23% of the sample. Plasma creatinine levels remained steady throughout the study and within the normal range. No side effects were reported.

    Full Text Available Abstract Background Cerebral palsy is the most common cause of physical disability in childhood, occurring in one in 500 children. It is caused by a static brain lesion in the neonatal period leading to a range of activity limitations. Oral motor and swallowing dysfunction, poor nutritional status and poor growth are reported frequently in young children with cerebral palsy and may impact detrimentally on physical and cognitive development, health care utilisation, participation and quality of life in later childhood. The impact of modifiable factors (dietary intake and physical activity on growth, nutritional status, and body composition (taking into account motor severity in this population is poorly understood. This study aims to investigate the relationship between a range of factors - linear growth, body composition, oral motor and feeding dysfunction, dietary intake, and time spent sedentary (adjusting for motor severity - and health outcomes, health care utilisation, participation and quality of life in young children with cerebral palsy (from corrected age of 18 months to 5 years.

    Full Text Available Mucosal surfaces have a fundamental participation in many aspects of the human immunodeficiency virus (HIV infection pathogenesis. In Brazilian HIV-1 infected subjects, loss of weight and appetite are among the most debilitating symptoms. In this review we describe a defined mucosal immunogen that has profound but transient effects on HIV viral load, and we suggest that gut associated lymphoid tissue under constant immunostimulation is likely to provide a major contribution to the total levels of HIV. We also show that hypermetabolism appears to play a role in the wasting process in Brazilian patients coinfected with HIV and tuberculosis.

    Roscoea purpurea (Zingiberaceae) is commonly known as "kakoli". Traditionally, various parts like leaves, roots and flower etc. are used for the treatment of diabetic, hypertension, diarrhea, fever, inflammation etc. In Nepal tubers are boiled for edible purpose and also used in traditional veterinary medicine. The study aims for nutritional characterization, chemical profiling of R. purpurea (tubers) methanol extract (RPE) along with evaluation of its anti-oxidant activity. Physicochemical and nutritional content were estimated as per standard protocols. Chemical profiling of markers includes method optimization, identification & quantification of bioactive poly phenolics through HPTLC. Anti oxidant potential RPE was analyzed via. Total phenolics (TPC), total flavonoids (TFC), reducing power assay, DPPH and β-carotene bleaching model. Physicochemical and nutritional standards were established. Kaempferol (0.30%), vanillic acid (0.27%), protocatechuic (0.14%), syringic (0.80%) and ferulic acid (0.05%) were identified and then quantified. TPC and TFC content were found to be 7.10 ± 0.115 and 6.10 ± 0.055%, reducing power of extract also increases linearly (r(2) = 0.946) with concentration, similar to standards. IC50 value of extract in DPPH and β-carotene bleaching model was observed at 810.66 ± 1.154 and 600.66 ± 1.154 µg/ml, which is significantly different from standards (p < 0.05). Although there is a positive, significant correlation between the phenolic and flavonoid content with anti oxidant activity of extract. Thus, study will authenticates the identity, utility of herb as nutrient supplement and an important medicinal plant having promising pharmacological activities for further elaborated/extended investigation work.

    To observe the effect of coix seed diet therapy on the nutritional status of peritoneal dialysis patients and to discuss the potential reasons. 30 dialysis patients with regular return visit to peritoneal dialysis center of Guangdong Provincial Hospital of Traditional Chinese Medicine were recruited and divided into two groups according to their willingness. 13 patients in control group continued their usual dialysis prescriptions and medications, whereas 30g of coix seed per day was added to the usual therapies of 17 patients in coix seed group. Changes in nutritional status of dialysis patients in two groups were evaluated after a 12-week treatment. Two patients (one in each group) quitted the study because of pulmonary infection. After treatment, the nutritional parameters of serum albumin level (P=0.004), total protein level (P=0.008), and body mass index (P=0.023) were increased significantly in coix seed group. And the statistical differences of serum albumin level and body mass index were significantly compared to control group (P=0.008 and P=0.032, respectively). Moreover, the C-reactive protein level had a significant decrease (P=0.001) and the clinical symptoms of dialysis patients including tiredness, anorexia, xerostomia, and abdominal distension showed a significant improvement (Pnutritional status of peritoneal dialysis patients by relieving digestive tract symptoms, increasing urinary volume, and meliorating micro-inflammatory state.

    There is a dearth of recent data on the relationship between nutritional status and intellectual development among children in India. To determine whether such a relationship exists, we studied children in a rural area of Tamil Nadu. We stratified villages in Kaniyambadi block, Tamil Nadu, and recruited consecutive children who satisfied the study criteria. We assessed nutritional status by measuring height and weight and recording chronological age, and calculated indices weight-for-age, height-for-age, weight-forheight and their Z scores. We assessed intellectual development using the Indian adaptation of the Vineland Social Maturity Scale. We used a case-control framework to determine the relationship and logistic regression to adjust for common confounders. We recruited 114 children between the ages of 12 and 72 months. Z score means (weight-for-age -1.36; height-for-age -1.42; weight-for-height -0.78) were much less than 0 and indicate undernutrition. Z score standard deviations (weight-for-age 1.04; height-for-age 1.18; weightfor- height 1.06) were within the WHO recommended range for good quality of nutrition data suggesting reduced measurement errors and incorrect reporting of age. The frequency distributions of population Z scores suggest high undernutrition, wasting and medium stunting. A tenth of the population (9.6%) had values to suggest borderline/below average intelligence (social quotient social quotient. These relationships remained statistically significant after adjusting for sex and socioeconomic status using logistic regression. Chronic undernutrition, wasting and stunting and their association with lower intellectual development demand an urgent re-assessment of national food policies and programmes.

    Laboratory-based studies demonstrate that fueling (carbohydrate; CHO) and fluid strategies can enhance training adaptations and race-day performance in endurance athletes. Thus, the aim of this case study was to characterize several periodized training and nutrition approaches leading to individualized race-day fluid and fueling plans for 3 elite male marathoners. The athletes kept detailed training logs on training volume, pace, and subjective ratings of perceived exertion (RPE) for each training session over 16 wk before race day. Training impulse/load calculations (TRIMP; min × RPE = load [arbitrary units; AU]) and 2 central nutritional techniques were implemented: periodic low-CHO-availability training and individualized CHO- and fluid-intake assessments. Athletes averaged ~13 training sessions per week for a total average training volume of 182 km/wk and peak volume of 231 km/wk. Weekly TRIMP peaked at 4,437 AU (Wk 9), with a low of 1,887 AU (Wk 16) and an average of 3,082 ± 646 AU. Of the 606 total training sessions, ~74%, 11%, and 15% were completed at an intensity in Zone 1 (very easy to somewhat hard), Zone 2 (at lactate threshold) and Zone 3 (very hard to maximal), respectively. There were 2.5 ± 2.3 low-CHO-availability training bouts per week. On race day athletes consumed 61 ± 15 g CHO in 604 ± 156 ml/hr (10.1% ± 0.3% CHO solution) in the following format: ~15 g CHO in ~150 ml every ~15 min of racing. Their resultant marathon times were 2:11:23, 2:12:39 (both personal bests), and 2:16:17 (a marathon debut). Taken together, these periodized training and nutrition approaches were successfully applied to elite marathoners in training and competition.

    Under- and overnutrition are linked to adverse outcomes during and after childhood cancer treatment. Therefore, understanding the timing of weight loss and weight gain and their contributory factors is essential for improving outcomes. We aimed to determine in which period of treatment changes in nutritional status occurred and which factors contributed to these changes. A prospective cohort study of 133 newly diagnosed cancer patients with hematological, solid, and brain malignancies was performed. Anthropometric data and related factors were assessed at 0, 3, 6 and 12 months after diagnosis. Despite initial weight loss at the beginning of treatment in patients with hematological and solid malignancies, body mass index (BMI) and fat mass (FM) increased within 3 months with 0.13 SDS (P < 0.001) and 0.05 SDS (P = 0.021) respectively. Increase continued during the following months and resulted in a doubling of the number of overnourished patients. Fat free mass (FFM), which was already low at diagnosis, remained low. During the entire study period about 17% of the patients were undernourished on the basis of low FFM. Tube feeding and diminished activity level were related to increases in BMI and %FM respectively. No relationship was found between energy intake or corticosteroids and increase in BMI or %FM. BMI and FM increased during and after the period of intensive treatment, while FFM remained low. Improvement of nutritional status might be accomplished by increasing physical activity from the early phase of treatment.

    The Nutrient Rich Foods (NRF) approach to eating uses the NRF Index, a nutrient profiling metric to help consumers choose foods that contain more vitamins, minerals, and other nutrients per kilocalorie. Research is needed to test the efficacy of dietary guidance using nutrient profiling systems to rank foods. To examine whether nutrition education and supporting materials would increase understanding of the NRF approach and improve food shopping, meal planning, consumption of nutrient-rich foods, and diet quality. Unbalanced randomized controlled trial conducted in February to May 2009 with participants assigned to NRF education group (n=128) or control group receiving standard nutrition education (n=61). Adult primary food shoppers and preparers with at least one child in the household aged 3 to 17 years. Group education session and support tools (pocket guide, shopping list, refrigerator magnet, weekly e-mail messages, and biweekly mailings). Surveys of knowledge, attitudes, and behaviors and two 24-hour telephone dietary recalls at baseline and after an 8-week intervention period. Examined time-by-treatment interactions in outcome measures. Compared to controls, NRF participants increased meal planning (+24.2% vs ?4.9%; Pfoods (+60.2% vs +24.6%; Ptrend), and consumed more vegetables and fruits (Ptrend). Significant improvements were observed in Healthy Eating Index component scores for total fruit; whole fruit; whole grains; saturated fat; and energy from solid fats, alcohol, and added sugars. Findings of this study showed that a consumer education program increased participants' use of the NRF approach and improved diet quality. Larger and longer-term studies are needed to confirm the findings and better understand processes of change. Copyright © 2012 Academy of Nutrition and Dietetics. Published by Elsevier Inc.

    The near infrared reflectance spectroscopy (NIRS) technique has been widely used in the study of ruminant nutrition with many of its operational merits such as facility, shortcut and accuracy, etc. Study suggested that the standard error of cross-validation (SECV) ranges from 1.6% to 2.8% in predicting organic matter digestion of ruminant diet by using the NIRS technique; the chemical and biological compositions and the microbial protein proportion in the duodenal digesta can be predicted accurately using the NIRS. However, the kinetic parameters of degradation are not well predicted; The prediction of intake of stall feeding animals by using NIRS is similar to the determination of in vivo method, but the standard error of prediction is about 14% when using the NIRS to predict intake of grazing animals. All of the studies suggest that big progress has been made in using NIRS technique to predict feed digestion and evaluate the diet quality and intake of ruminant animals, which also suggest that the NIRS technique has a wide prospect in the study of ruminant nutrition.

    Nutrition is one of the fundamentals of care provided to critically ill adults. The volume of enteral nutrition received, however, is often much less than prescribed due to multiple functional and process issues. To deliver the prescribed volume and correct the energy deficit associated with enteral nutrition alone, parenteral nutrition can be used in combination (termed "supplemental parenteral nutrition"), but benefits of this method have not been firmly established. A multi-centre, randomised, clinical trial is currently underway to determine if prescribed energy requirements can be provided to critically ill patients by using a supplemental parenteral nutrition strategy in the critically ill. This prospective, multi-centre, randomised, stratified, parallel-group, controlled, phase II trial aims to determine whether a supplemental parenteral nutrition strategy will reliably and safely increase energy intake when compared to usual care. The study will be conducted for 100 critically ill adults with at least one organ system failure and evidence of insufficient enteral intake from six intensive care units in Australia and New Zealand. Enrolled patients will be allocated to either a supplemental parenteral nutrition strategy for 7 days post randomisation or to usual care with enteral nutrition. The primary outcome will be the average energy amount delivered from nutrition therapy over the first 7 days of the study period. Secondary outcomes include protein delivery for 7 days post randomisation; total energy and protein delivery, antibiotic use and organ failure rates (up to 28 days); duration of ventilation, length of intensive care unit and hospital stay. At both intensive care unit and hospital discharge strength and health-related quality of life assessments will be undertaken. Study participants will be followed up for health-related quality of life, resource utilisation and survival at 90 and 180 days post randomisation (unless death occurs first). This trial

    Midorikawa, Y.; Fujii, T.; Ohira, A.; Nitta, K.

    At the 40th IAF Congress in Malaga, a nutrition system for a lunar base CELSS was presented. A lunar base with a total of eight crew members was envisaged. In this paper, four species of plants—rice, soybean, lettuce and strawberry—were introduced to the system. These plants were sufficient to satisfy fundamental nutritional needs of the crew members. The supply of nutrition from plants and the human nutritional requirements could almost be balanced. Our study revealed that the necessary plant cultivation area per crew member would be nearly 40 m 3 in the lunar base. The sources of nutrition considered in the study were energy, sugar, fat, amino acids, inorganic salt and vitamins; however, calcium, vitamin B 2, vitamin A and sodium were found to be lacking. Therefore, a subsystem to supply these elements is of considerable value. In this paper, we report on a study for breeding snails and utilizing meat as food. Nutrients supplied from snails are shown to compensate for the abovementioned lacking elements. We evaluate the snail breeder and the associated food supply system as a subsystem of closed ecological life support system.

    To investigate the effects of early enteral nutrition (EEN) on intra-abdominal pressure (IAP) and disease severity in patients with severe acute pancreatitis (SAP). Enteral nutrition (EN) was started within 48 h after admission in the EEN group and from the 8th day in the delayed enteral nutrition (DEN) group. The IAP and intra-abdominal hypertension (IAH) incidence were recorded for 2 weeks. The caloric intake and feeding intolerance (FI) incidence were recorded daily after EN was started. The severity markers and clinical outcome variables were also recorded. Sixty patients were enrolled to this study. No difference about IAP was found. The IAH incidence of the EEN group was significantly lower than that of the DEN group from the 9th day (8/30 versus 18/30; P = 0.009) after admission. The FI incidence of the EEN group was higher than that of the DEN group during the initial 3 days of feeding (25/30 versus 12/30; P = 0.001; 22/30 versus 9/30; P = 0.001; 15/30 versus 4/30; P = 0.002). Patients with an IAP FI incidence than those with an IAP ≥15 mmHg on the 1st day (20/22 versus 17/38; P < 0.001), the 3rd day (11/13 versus 8/47; P < 0.001), and the 7th day (3/5 versus 3/55; P = 0.005) of feeding. The severity markers and clinical outcome variables of the EEN group were significantly improved. Early enteral nutrition did not increase IAP. In contrast, it might prevent the development of IAH. In addition, EEN might be not appropriate during the initial 3-4 days of SAP onset. Moreover, EN might be of benefit to patients with an IAP <15 mmHg. Early enteral nutrition could improve disease severity and clinical outcome, but did not decrease mortality of SAP.

    Being a signatory to international agreements that recognize the Human Right to Adequate Food (HRAF) and having enshrined this right into its Constitution, the Brazilian state imposes a duty to provide, protect and promote the HRAF. For this it is necessary to incorporate the principles of the HRAF into the process of planning and executing the actions of Food and Nutrition Security (FNS). The objective was to analyze the process of mainstreaming of the HRAF in the new institutional design of the National School Nutrition Program (NSNP). This is in line with the principles laid down in General Comment No 12 of the Guide for Policy Analysis and Public Programs and nutritional Food Security under the Perspective of Human Rights and the Organic Law on Food and Nutrition Security (OLFNS). The results show that the new regulatory framework of the NSNP indicates a paradigm shift that is characterized by a gradual decline in the perception of NSNP as policy of a welfare nature. Concomitantly, there is an increase in the concept of the benefit of school food as a right, with the caveat that the construction of a new regulatory framework, although essential, is not sufficient for full implementation of the HRAF.

    771 children from Baras, Rizal, and Pasay City, Philippines were studied. House interviews of mothers using precoded questionnaires were conducted and the children were given a complete physical examination. The study objectives were to compare the health and nutritional status of children in a rural and an urban area in greater Manila and to determine how family size affects the nutritional status of children 3 years and younger. The following were among the study results: 1) the weight curves of both urban and rural groups were similar until age 4-1/2 years, but beyond this age the mean weight curve of the rural group exceeded that of the urban group; 2) urban children between ages 1-5 enjoyed a height advantage; 3) there was a positive correlation between malnutrition and excessive family size; 4) the high prevalence of malnutrition among children 1-4 years of age was due to food deprivation because of poverty, parental ignorance, inappropriate folklores, oversized families, high episodes of illnesses, and inadequate medical care; and 5) dietary assessment of both groups showed the inadequacy of the quality and quantity of basic nutrients and elements needed for growth, development, and repair of tissues.

    Full Text Available OBJECTIVES: A common method for conducting a quantitative systematic review (QSR for observational studies related to nutritional epidemiology is the “highest versus lowest intake” method (HLM, in which only the information concerning the effect size (ES of the highest category of a food item is collected on the basis of its lowest category. However, in the interval collapsing method (ICM, a method suggested to enable a maximum utilization of all available information, the ES information is collected by collapsing all categories into a single category. This study aimed to compare the ES and summary effect size (SES between the HLM and ICM. METHODS: A QSR for evaluating the citrus fruit intake and risk of pancreatic cancer and calculating the SES by using the HLM was selected. The ES and SES were estimated by performing a meta-analysis using the fixed-effect model. The directionality and statistical significance of the ES and SES were used as criteria for determining the concordance between the HLM and ICM outcomes. RESULTS: No significant differences were observed in the directionality of SES extracted by using the HLM or ICM. The application of the ICM, which uses a broader information base, yielded more-consistent ES and SES, and narrower confidence intervals than the HLM. CONCLUSIONS: The ICM is advantageous over the HLM owing to its higher statistical accuracy in extracting information for QSR on nutritional epidemiology. The application of the ICM should hence be recommended for future studies.

    The Northern Plains Indians of the Cheyenne River Sioux Tribe have experienced significant lifestyle and dietary changes over the past seven generations that have resulted in increased rates of diabetes and obesity. The objective of this study was to determine if Northern Plains Indians with type 2 diabetes mellitus who are randomized to receive culturally adapted educational lessons based on the Medicine Wheel Model for Nutrition in addition to their usual dietary education will have better control of their type 2 diabetes than a nonintervention, usual care group who received only the usual dietary education from their personal providers. A 6-month, randomized, controlled trial was conducted January 2005 through December 2005, with participants randomized to the education intervention or usual care control group. The education group received six nutrition lessons based on the Medicine Wheel Model for Nutrition. The usual care group received the usual dietary education from their personal providers. One hundred fourteen Northern Plains Indians from Cheyenne River Sioux Tribe aged 18 to 65 years, with type 2 diabetes. Weight, body mass index (BMI), hemoglobin A1c, fasting serum glucose and lipid parameters, circulating insulin, and blood pressure were measured at the beginning and completion. Diet histories, physical activity, and dietary satiety surveys were measured at baseline and monthly through completion. Differences were determined using Student t tests, chi(2) tests, and analysis of variance. The education group had a significant weight loss (1.4+/-0.4 kg, Pnutrition intervention promoted small but positive changes in weight. Greater frequency and longer duration of educational support may be needed to influence blood glucose and lipid parameters.

    Full Text Available Abstract Background Nutrition clubs (NC operate in community settings and provide members with nutrition education and meal replacements for weight management. NC are owned and operated by distributors of Herbalife products. There are over 6200 NC in the US, but there has been no independent assessment of the association of these NC with biomarkers of health. Methods We conducted a cross-sectional pilot study to compare the health status of 100 NC members to 100 community-matched controls (CC in the greater Boston area. Each CC was matched to a NC member for community of residence (zip code, age category, gender, BMI category, race/ethnicity, education level (category, and readiness to make health changes. Measures obtained included cardio-metabolic risk factors, body composition, markers of nutritional status, reported health status, dietary intake, physical activity, sleep and depression. Results Participants were predominantly female (64% and Hispanic (73%. NC members had significantly lower fasting insulin (P < 0.001 and lower HbA1c (P = 0.008, higher levels of 25 hydroxy-vitamin D (P = 0.001, and vitamin E:cholesterol ratio (P < 0.001, and lower prevalence of metabolic syndrome (P = 0.02 compared to CC. In addition, most of the NC members (99% were satisfied with Herbalife NC membership for themselves and their families. A higher percentage of NC members (86% compared to CC (32% reported being in much better or somewhat better health compared to a year ago (P < 0.001; and they reported significantly better physical health (P = 0.03, and fewer sleep problems (P = 0.03. Conclusion Herbalife NC membership was positively associated with perceived health and measured cardiometabolic benefits. However, causality cannot be inferred from these findings.

    Hydration and nutritional status of end stage renal disease (ESRD) patients are linked to increased morbidity and mortality. Body composition monitoring (BCM) by multi-frequency bioimpedance spectroscopy (MFBS) is considered to be a superior modality of fluid assessment in chronic kidney disease (CKD) dialysis. We did a longitudinal prospective study in South India on maintenance hemodialysis (MHD) and continuous ambulatory peritoneal dialysis (CAPD) patients over 24 months and looked at impact of baseline nutritional parameters and body composition parameters on 24-month mortality. Ninety-nine patients stable on dialysis for at least 3 months were recruited (MHD 85, CAPD 14) at baseline and at 24 months, 41 were alive and 33 had expired, 12 had undergone renal transplant and 13 were lost to follow-up. BCM and nutritional assessment were done at baseline and at follow-up. Baseline overhydration (OH) differed significantly between surviving and dead patients (p < 0.05). Receiver operating characteristic (ROC) curve between OH and mortality showed that the best cut-off point to differentiate between survived and expired patients was 3.15 L. ROC curve for BMI showed lower than cut-off of 22.65 kg/m(2) to predict mortality with sensitivity 41.30% and specificity 81.81%. At follow-up, triceps skin fold thickness (TSF), biceps skin fold thickness (BSF) and mid arm circumference (MAC) increased significantly from baseline (p < 0.001, p = 0.001 and p < 0.001, respectively). Overhydration and BMI are important predictors of mortality in dialysis patients. Improvement in anthropometric markers TSF, BSF and MAC in MHD patients was associated with survival.
