Biofortification of rice (Oryza sativa L.) with micronutrients is widely recognized as a sustainable strategy to alleviate human iron (Fe) and zinc (Zn) deficiencies in developing countries where rice is the staple food. Constitutive overexpression of the rice nicotianamine synthase (OsNAS) genes has been successfully implemented to increase Fe and Zn concentrations in unpolished and polished rice grain. Intensive research is now needed to couple this high-micronutrient trait with high grain yields. We investigated associations of increased grain Fe and Zn concentrations with agro-morphological traits of backcross twice second filial (BC2F2) transgenic progeny carrying OsNAS1 or OsNAS2 overexpression constructs under indica/japonica and japonica/japonica genetic backgrounds...

BACKGROUND: The Global Burden of Diseases, Injuries, and Risk Factors Study 2015 provides an up-to-date synthesis of the evidence for risk factor exposure and the attributable burden of disease. By providing national and subnational assessments spanning the past 25 years, this study can inform debates on the importance of addressing risks in context. METHODS: We used the comparative risk assessment framework developed for previous iterations of the Global Burden of Disease Study to estimate attributable deaths, disability-adjusted life-years (DALYs), and trends in exposure by age group, sex, year, and geography for 79 behavioural, environmental and occupational, and metabolic risks or clusters of risks from 1990 to 2015...

OBJECTIVE: Micronutrient deficiencies can lead to anemia, growth restriction, and poor motor and cognitive development. A clinical trial was planned to assess the impact of nutritional supplementation on cognitive measures in preschool children. Conducting clinical trials in children is difficult due to underlying laws, hesitation of the research community, and difficult enrollment. We carried out a questionnaire-based feasibility survey to assess the interest of parents towards participation in such a nutrition-based study...

World Health Organization is concerned for parental vitamin deficiency and its effect on offspring health. This study examines the effect of a marginally dietary-induced parental one carbon (1-C) micronutrient deficiency on embryonic gene expression using zebrafish. Metabolic profiling revealed a reduced 1-C cycle efficiency in F0 generation. Parental deficiency reduced the fecundity and a total of 364 genes were differentially expressed in the F1 embryos. The upregulated genes (53%) in the deficient group were enriched in biological processes such as immune response and blood coagulation...

Users of food pantries often have a long history of food insecurity and may be vulnerable to nutritional deficiencies. The quality of their diets is not well researched. The purpose of this systematic review was to summarize the published evidence about the dietary quality of food pantry users. Systematic database searches of PubMed, PsycINFO, PsycARTICLES, and Psychology Behavioral Sciences Collection, and hand searches of references were conducted to identify cross-sectional, cohort, and intervention studies reporting baseline data, conducted in high-income countries and published between 1980 and 2015, which reported on the nutritional adequacy of individuals who have used a food pantry at least once in the previous 12 months...

Deprivation of mineral nutrients causes significant retardation of plant growth. This retardation is associated with nutrient specific and general stress-induced transcriptional responses. In this study we adjusted the external supply of iron, potassium and sulfur to cause the same retardation of shoot growth. Nevertheless, limitation by individual nutrients resulted in specific morphological adaptations and distinct shifts within the root metabolite fingerprint. The metabolic shifts affected key metabolites of primary metabolism and the stress-related phytohormones, jasmonic-, salicylic- and abscisic acid...

There is an expanding prevalence pool of heart failure (HF) due to the increasing prevalence of survivors of myocardial infarction, diabetes, hypertension, chronic kidney disease, and obesity. There is increasing interest in the role of nutrition in all forms of HF, given observations concerning micro- and macronutrient deficiencies, loss of lean body mass or sarcopenia, and their relationships with hospitalization and death. This review examines the relationships among loss of lean body mass, macro- and micronutrient intake, and the natural history of HF, particularly in the elderly, in whom the risks for all-cause rehospitalization, infection, falls, and mortality are increased...

Building upon the growing interest and research on genetically modified (GM) biofortification, its socioeconomic potential has been increasingly examined. We conducted two systematic reviews and meta-analyses to provide comprehensive evidence of consumers' willingness to pay (11 economic valuation studies, 64 estimates) and cost-effectiveness/benefits (five economic evaluation studies, 30 estimates). Worldwide, consumers were willing to pay 23.9% more for GM biofortified food crops. Aside from crop and design-related differences, information provision was deemed crucial...

Iron and zinc deficiencies negatively impact human health worldwide. We developed wheat lines that meet or exceed recommended dietary target levels for iron and zinc in the grains. These lines represent useful germplasm for breeding new wheat varieties that can reduce iron and zinc deficiency-associated health burdens in the affected populations. Micronutrient deficiencies, including iron and zinc deficiencies, have negative impacts on human health globally. Iron-deficiency; anemia affects nearly two billion people worldwide and is the cause of reduced cognitive development, fatigue and overall low productivity...

Zinc is an essential micronutrient that strongly influences human health and nutrition through its involvement in several biological processes. Zinc functions as structural and functional component of many transcription factors and enzymes that regulate cell growth, gene expression, and immune response, and its deficiency can lead to retarded growth and impaired immune functions. The physiological functions of zinc are dependent on its bioavailability in tissues, which in turn depends on intestinal absorption of dietary zinc...

BACKGROUND: Micronutrient deficiency in Tanzania is a significant public health problem, with vitamin A deficiency (VAD) affecting 34% of children aged 6 to 59 months. Since 2007, development partners have worked closely to advocate for the inclusion of twice-yearly vitamin A supplementation and deworming (VASD) activities with budgets at the subnational level, where funding and implementation occur. As part of the advocacy work, a VASD planning and budgeting tool (PBT) was developed and is used by district officials to justify allocation of funds...

The essentiality of 14 mineral elements so far have been reported in plant nutrition. Eight of these elements were known as micronutrients due to their lower concentrations in plants (usually ≤100 mg/kg/dw). However, it is still challenging to mention an exact number of plant micronutrients since some elements have not been strictly proposed yet either as essential or beneficial. Micronutrients participate in very diverse metabolic processes, including from the primary and secondary metabolism to the cell defense, and from the signal transduction to the gene regulation, energy metabolism, and hormone perception...

Cereals are a major source of dietary energy and protein but are nutritionally poor in micronutrients. Zinc (Zn) biofortification of staple crops has been proposed as a promising strategy to combat the global challenge of human Zn-deficiency. The aim of this study was to improve the Zn content in the edible part of the barley (Hordeum vulgare L.) grain by enhancing Zn translocation into the developing seeds. We demonstrate that the barley plasma membrane P-type ATPase Zn transporter, HvHMA2 is an efficient candidate for mineral biofortification of crops...
