    ABSTRACT: Micronutrient deficiencies are still a public health problem in Vietnam. The Government of Vietnam has taken several steps to improve the situation through issuing supportive policy documents over the last several decades. Food fortification is an important complementary strategy to help bridge the nutrient gap in the population. Currently technical regulations are in place and food fortification is taking place on a voluntary basis, along with other complementary targeted programs including home fortification of complementary foods with micronutrient powders and a communications campaign to reach adolescent girls. These have been built on innotative partnerships with industries on a voluntary, market basis. Other innovative targeted nutrition programs are also being piloted, including a micronutrient supplement project in four provinces and a campain to reach adolescent girls through sports. High level political commitment and resources is a crucial element to scale up in Vietnam. A micronutrient survey planned in 2015 will help provide the evidence to support a possible mandatory decree on food fortification. Vietnam has built a solid foundation in order to scale up its national food fortification program in the future to reach the majority of the population with improved intakes of iron, vitamin A, zinc, and iodine.

    ABSTRACT: Changes in lifestyle have led to better nutrition or increasing the risk of NCDs in Asia, while there are still many children and reproductive-aged women (RAW) suffering undernutrition whose lives are at risk in the same region.The MDG of reducing the prevalence of underweight <5 children to half has been achieved already or nearly achieved in many Asian countries, whereas South Asian (SA) countries and several other countries (Cambodia, Laos, East Timor and Yemen) have difficulties in achieving the goal by 2015. In particular, East Timor and Yemen are in a critical situation with undernutrition. There is a strong concern about a rapid increase in overweight and obesity rates in West Asian (WA) and some Central Asian (CA) countries. Iron deficiency is one of the most important risk factors that threaten healthy life among RAW especially in SA, followed by Southeast Asia (SEA) and CA. The same issue is observed among children (1-4 y) in the same regions. Dietary risks (based on DALYS) increase with advancing age in most Asian regions whereas high Body Mass Index is the most important risk factor in WA and some CA countries. High priority should be placed on measures to tackle undernutrition and micronutrient deficiencies including iron deficiency in SA and some countries in SEA and WA; overweight and obesity in WA and CA; and dietary risks among RAW, in most Asian regions.

    ABSTRACT: Lifestyle-related diseases have complex pathogenesis which consists of several different steps. Basic causes of the diseases are attributed to unhealthy lifestyles in dietary habits, physical activity and suffering stress. The unhealthy lifestyles induce risk factors such as hypertension, dyslipidemia, obesity, and hyperglycemia. These risk factors all promote arteriosclerosis leading to serious vascular complications (i.e., thrombotic diseases), myocardial infarction and cerebral infarction. The total number of deaths from these thrombotic diseases almost equals that from cancer in our country. Cancer is also a typical lifestyle-related disease. Food has three different functions: the primary function is to provide enough nutrients to meet the metabolic requirements. The secondary function is the one relating to food preference. The third function is to control our body functions, which help reduction of the risk of diseases. Some of the compounds derived from food, especially phytochemicals in edible plants, vegetables and herbs, have potent functions to control our body functions and contribute to promoting our health. In this review article, we overview the lifestyle-related diseases and food functions involving prevention and amelioration of the diseases by food components especially from edible plants and vegetables. As an example, we will describe the food function of garlic and the prevention of lifestyle-related diseases by its components. Allyl sulfides are characteristic flavor compounds derived from garlic, and these organosulfur compounds are responsible for the food function of garlic.

    ABSTRACT: Food allergy is defined as an immune system-mediated adverse reaction to food components. Food allergic reactions are mostly IgE mediated and also known as immediate type hypersensitivity (type I reaction). There are several characteristic clinical types of food allergy, such as Anaphylaxis, Food-dependent exercise-induced anaphylaxis (FDEIA), and Oral allergy syndrome (OAS). In addition, food allergy is also classified into two types (class 1 and class 2) based on the pathophysiological mechanism. In the class 2 food allergy, pollen allergy causes plant food allergy; therefore this type of allergy is sometimes called Pollen-food allergy syndrome (PFAS). The risk of food allergy (allergenicity) may vary with the treatment of the food allergens. The formation or status of the causative food affects its allergenicity. Class 1 food allergens are generally heat-, enzyme-, and low pH-resistant glycoproteins ranging in size from 10 to 70 kD. Class 1 food allergens induce allergic sensitization via the gastrointestinal tract and are responsible for systemic reactions. Class 2 food allergens are generally heat-labile, susceptible to digestion, and highly homologous with pollen allergens. Taken together, it may be important to consider the diversity of food allergy in order to fight against food allergy.

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

    ABSTRACT: Obesity is a major risk factor for chronic diseases such as diabetes, cardiovascular diseases, and hypertension. Many modern people have a tendency to overeat owing to stress and loosening of self-control. Moreover, energy expenditure varies greatly among individuals. Scientific reduction of obesity is important under these circumstances. Furthermore, recent research on molecular levels has clarified the differentiation of adipocytes, the level of subsequent fat accumulation, and the secretion of the biologically active adipokines by adipocytes. Adipose tissues and obesity have become the most important target for the prevention and treatment of many chronic diseases. We have identified various food-derived compounds modulating nuclear receptors, especially peroxisome proliferators-activated receptor(PPAR), in the regulation of energy metabolism and obesity. In this review, we discuss the PPARs that are most important in obesity and energy metabolism.

    ABSTRACT: Innovative approaches are needed to impact obesity and other diet-related chronic diseases, including tested interventions at the environmental and policy levels. We have conducted multi-level community trials in low-income minority settings in the United States and other countries that test interventions to improve the food environment, support policy, and reduce the risk for developing obesity and other diet-related chronic diseases. All studies have examined change from pre- to post-study, comparing an intervention with a comparison group. Our results have shown consistent positive effects of these trials on consumer psychosocial factors, food purchasing, food preparation and diet, and, in some instances, obesity. We have recently implemented a systems science model to support programs and policies to improve urban food environments. Environmental interventions are a promising approach for addressing the global obesity epidemic due to their wide reach. Further work is needed to disseminate, expand and sustain these initiatives through policy at the city, state and federal levels.

    ABSTRACT: Metabolic syndrome is a cluster of metabolic disorders that contribute to increased cardiovascular morbidity and mortality. Although the pathogenesis of metabolic syndrome is complicated, dietary lipids have been recognized as contributory factors in the development and the prevention of cardiovascular risk clustering. We investigated the physiological functions and molecular actions of functional lipids, especially omega3-polyunsaturated fatty acid (PUFA)-containing lipids, in the development of metabolic syndrome using obese model animals. Feeding of omega3-PUFA-containing lipids, such as eicosapentaenoic acid, docosapentaenoic acid, docosahexaenoic acid, tetracosahexaenoic acid, and omega3-phosphatidylcholine, alleviated hepatic lipid accumulation through the suppression of lipogenic gene expression in the liver. Additionally, dietary omega3-PUFA-containing lipids increased serum adiponectin levels in obese animal models. Their molecular actions in the prevention and alleviation of metabolic syndrome could be attributed to the regulation of the activity or abundance of several transcriptional factors in the liver and adipose tissue. Dietary functional lipids would be useful to prevent or alleviate metabolic syndrome in obese animals. In particular, the function of omega3-containing lipids as dietary adiponectin inducers deserves attention with respect to alleviation of metabolic syndrome by dietary manipulation.

    ABSTRACT: Pyridine nucleotide coenzymes (PNCs) are involved in over 500 enzyme reactions. PNCs are biosynthesized from the amino acid L-tryptophan (L-Trp), as well as the vitamin niacin. Hence, "true" niacin-deficient animals cannot be "created" using nutritional techniques. We wanted to establish a truly niacin-deficient model animal using a protocol that did not involve manipulating dietary L-Trp. We generated mice that are missing the quinolinic acid phosphoribosyltransferase (QPRT) gene. QPRT activity was not detected in qprt(-/-)mice. The qprt(+/+), qprt(+/-) or qprt(-/-) mice (8 wk old) were fed a complete diet containing 30 mg nicotinic acid (NiA) and 2.3 g L-Trp/kg diet or an NiA-free diet containing 2.3 g L-Trp/kg diet for 23 d. When qprt(-/-)mice were fed a complete diet, food intake and body weight gain did not differ from those of the qprt(+/+) and the qprt(+/-) mice. On the other hand, in the qprt(-/-) mice fed the NiA-free diet, food intake and body weight were reduced to 60% (p<0.01) and 70% (p<0.05) of the corresponding values for the qprt(-/-) mice fed the complete diet at day 23, respectively. The nutritional levels of niacin such as blood and liver NAD concentrations were also lower in the qprt(-/-) mice than in the qprt(+/+) and the qprt(+/-) mice. Urinary excretion of quinolinic acid was greater in the qprt(-/-) mice than in the qprt(+/+) and the qprt(+/-) mice (p<0.01). These data suggest that we generated truly niacin-deficient mice.

    ABSTRACT: Prospective cohort studies have shown that people with a larger amount of physical activity (PA) and exercise have lower risks of non-communicable diseases (NCDs). In Japan, the Ministry of Health, Labour and Welfare published in March 2013 the "Active-Guide," i.e. the Japanese official PA guidelines for health promotion. In this document, the most important message is "+10," standing for "add 10 min of MVPA per day." The establishment of the "+10" recommendation is supported by strong scientific evidence. Firstly, a meta-analysis including 26 cohort studies indicated that an increment of 10 min of moderate-to-vigorous PA per day can result in a 3.2% reduction of the average relative risk of NCDs, dementia, joint-musculoskeletal impairment, and mortality. Secondly, the National Health and Nutrition Survey (Japan, 2010) reported that 60.8% of the Japanese population is inclined to add the equivalent of 10 min of PA in their daily life. In line with these results, the "+10" recommendation is viewed as feasible and efficient for the Japanese population. To our knowledge, this implementation of an additional low-dose PA recommendation in a governmental health promotion policy is a world first. We hope that the Japanese PA policy will inspire other national and international public health agencies.

    ABSTRACT: Although exposure assessment of the usual diet is an essential component of nutrition epidemiology, it remains one of the most challenging issues in the field. Dietary exposure is widely measured using Food Frequency Questionnaires (FFQs), which impose a low burden on respondents and are inexpensive in large-scale studies. FFQs have long satisfied the needs of epidemiological research, and have helped deliver the tremendous recent growth in knowledge of the diet-disease association. However, issues surrounding measurement errors with FFQs have attracted substantial research interest around the world. Attenuation of the diet-disease association due to measurement errors identified in Western populations has led to extended methodological investigations comparing the performance of FFQs with biomarkers. The need for better dietary assessment methods has increased. Dietary records or recall provide relatively accurate estimates of intake for specific days, and of the usual diet if collected on multiple days. Until recently, however, their use in large-scale studies was not feasible, mainly due to cost. One innovative tool which may overcome the limitations of dietary records or recall is computerized 24-h dietary recall systems. These systems have been demonstrated to provide high-quality dietary intake data among Western populations. Incorporation of such new technology into large-scale epidemiological studies would make multiple-day administration of 24-h recall feasible in terms of cost. Research efforts to improve dietary assessment among Japanese and Asian populations are still under development. The development of innovative methods for Japanese remains an urgent research challenge.

    ABSTRACT: Food prices and diet costs contribute to socioeconomic disparities in diet quality and health. Lower-cost diets provide ample calories but lack essential nutrients. Nutrition economics can remedy health disparities by helping to identify food patterns that are nutrient-rich, affordable, and appealing. First, nutrient profiling models-such as the Nutrient Rich Food (NRF) family of indices-are able to separate foods that are energy-dense from those that are nutrient-rich. Whereas energy-dense foods contain more calories than nutrients, nutrient-rich foods contain more nutrients than calories. Second, new value metrics have identified affordable healthy foods, based on nutrients per unit cost. Third, these methods have now been applied to the analyses of individual foods and beverages, meals, menus, and the total diet. The Healthy Eating Index (HEI), based on compliance with dietary guidelines, was the principal measure of total diet quality. Although healthier diets did generally cost more, some population subgroups managed to obtain nutrient-dense diets at a lower cost. Being able to create affordable, healthy food patterns on limited budgets is an example of nutrition resilience.

    ABSTRACT: There are several thermosensitive transient receptor potential (TRP) ion channels including capsaicin receptor, TRPV1. Food components activating TRPV1 inhibit body fat deposition through sympathetic nerve stimulation. TRPA1 is another pungency sensor for pungent compounds and is mainly coexpressed with TRPV1 in sensory nerve endings. Therefore, TRPA1 activation is expected to have an anti-obesity effect similar to TRPV1 activation. We have searched for agonists for TRPV1 and TRPA1 in vitro from Asian spices by the use of TRPV1- and TRPA1-expressing cells. Further, we performed food component addition tests to high-fat and high-sucrose diets in mice. We found capsiate, capsiconiate, capsainol from hot and sweet peppers, several piperine analogs from black pepper, gingeriols and shogaols from ginger, and sanshools and hydroxysanshools from sansho (Japanese pepper) to be TRPV1 agonists. We also identified several sulfides from garlic and durian, hydroxy fatty acids from royal jelly, miogadial and miogatrial from mioga (Zingiber mioga), piperine analogs from black pepper, and acetoxychavicol acetate (ACA) from galangal (Alpinia galanga) as TRPA1 agonists. Piperine addition to diets diminished visceral fats and increased the uncoupling protein 1 (UCP1) in interscapular brown adipose tissue (IBAT), and black pepper extract showed stronger effects than piperine. Cinnamaldehyde and ACA as TRPA1 agonists inhibited fat deposition and increased UCP1. We found that several agonists of TRPV1 and TRPA1 and some agonists of TRPV1 and TRPA1 inhibit visceral fat deposition in mice. The effects of such compounds on humans remain to be clarified, but we expect that they will be helpful in the prevention of obesity.

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

    ABSTRACT: Prevention of malnutrition in infants and children is multifaceted and requires the following: access to and intake of nutritious food starting at birth with exclusive breastfeeding for the first 6 mo of life, continued breastfeeding in combination with complementary foods from 6-24 mo of age, access to clean drinking water and sanitation, and access to preventive and curative health care (including prenatal). Nutrient-dense complementary foods can improve nutritional status and have long-term benefits; however, in a review of plant-based complementary foods in developing countries, most of them failed to meet many micronutrient requirements. There is need to provide other cost-effective alternatives to increase the quality of the diet during the complementary feeding stage of the lifecycle. This paper provides an overview of the development, testing, efficacy and effectiveness of the delivery of KOKO Plus on the growth and nutritional status of infants 6-24 mo of age.

    ABSTRACT: Food hygiene and a sufficient food supply are essential requirements to stay healthy. However, this can be hindered by foodborne infections, which are known to be prevalent throughout the world. The World Health Organization reports that, annually, diarrheal disease is responsible for the deaths of over 2 million people worldwide. The majority of these deaths occur in developing countries, following the ingestion of pathogen-contaminated food and water. In the developed world, outbreaks of foodborne diseases are also frequently documented, reflecting the global importance of following good food hygiene practices.

    ABSTRACT: Over a third of all deaths of children under the age of five are linked to undernutrition. At a 90% coverage level, a core group of ten interventions inclusive of infant and young child nutrition could save one million lives of children under 5 y of age (15% of all deaths) (Lancet 2013). The infant and young child nutrition package alone could save over 220,000 lives in children under 5 y of age. High quality proteins (e.g. milk) in complementary, supplementary and rehabilitation food products have been found to be effective for good growth. Individual amino acids such as lysine and arginine have been found to be factors linked to growth hormone release in young children via the somatotropic axis and high intakes are inversely associated with fat mass index in pre-pubertal lean girls. Protein intake in early life is positively associated with height and weight at 10 y of age. This paper will focus on examining the role of protein and amino acids in infant and young child nutrition by examining protein and amino acid needs in early life and the subsequent relationship with stunting.
