INTRODUCTION: Anaemia is a major global health problem affecting about 43% of preschool children globally and 60% of 6-24-month-old children in rural Bangladesh, half of which is attributed to iron deficiency (ID). Although WHO recommends universal supplementation with iron or home fortification with iron-containing multiple micronutrient powders (MMPs) to children under 2 years, evidence for benefits of these interventions on childhood development (a key rationale for these interventions) and harms (especially infection) remains limited...

Securing accurate measurements of dietary intake across populations is challenging. Of the methods, self-reported 24-h recalls are often used in low-income countries (LICs) because they are quick, culturally sensitive, do not require high cognitive ability, and provide quantitative data on both foods and nutrients. Measuring intakes via 24-h recalls involves 1) collecting data on food intakes, 2) the appropriate use of relevant food-composition data for calculating nutrient intakes, and 3) statistically converting observed intakes to "usual intakes" for evaluating nutrient adequacy or relations between foods and nutrients and health outcomes...

Over the past two decades, increasing efforts have been made to find suitable nutritional products for managing particularly moderate forms of malnutrition following acute phase treatment, including the adoption of ready-to-use therapeutic foods. The challenge in meeting nutrient needs of normal growing young children and other vulnerable population groups with scant food supply has led us to explore the use of local, traditional and culturally adaptable food-based complementary foods employing the food multimix (FMM) concept...

BACKGROUND: Significant efforts have been made to improve the nutritional support of very preterm infants. Large surveys may help to know the nutritional practices for preterm infants in neonatal units and identify if they are in line with the current guidelines. METHODS: A multicentre nationwide web-based survey on clinical feeding practices in very low birth weight (VLBW) infants was conducted in tertiary neonatal hospitals that admit infants with a birth weight < 1,500 g and/or a gestational age of < 32 weeks...

Folate is required for metabolic processes and neural development. Insuring its adequate levels for pregnant women through supplementation of grain-based foods with synthetic folic acid (FA) in order to prevent neural tube defects has been an ongoing public health initiative. However, because women are advised to take multivitamins containing FA before and throughout pregnancy, the supplementation together with natural dietary folates has led to a demographic with high and rising serum levels of unmetabolized FA...

In 1980 Smithells et al. reported that the intake of folic acid (FA) prevents the recurrence of neural tube defects (NTDs) [1]. After this and several other studies were conducted, the intake of 400 micrograms of folic acid per day, at least three months before and three months during pregnancy for prevention of NTD, was proposed [2,3,4]. Other strategies were also developed to increase folate blood levels in woman of childbearing age such as promoting the consumption of folate rich foods and food fortification (flour and most recently rice) [5]...

INTRODUCTION: Adolescence is a period of life that is a bridge between childhood and adulthood. India has the world's largest adolescent girl's population, and adolescent girls are an important vulnerable group of population. Perceived health is a predictor of morbidity and mortality in adults and has been an important marker of the health status in population health studies for decades. The aim of the study was to describe adolescent's perception of health and association between some factors such as nutrition status, socioeconomic status (SES), and health status...

Zinc oxide (ZnO) nanoparticles (NPs) have been widely used for food fortification, because zinc is essential for many enzyme and hormone activities and cellular functions, but public concern about their potential toxicity is increasing. Interactions between ZnO and biomatrices might affect the oral absorption, distribution, and toxicity of ZnO, which may be influenced by particle size. In this study, ZnO interactions with biomatrices were investigated by examining the physicochemical properties, solubility, protein fluorescence quenching, particle-protein corona, and intestinal transport with respect to the particle size (bulk vs...

A simple and rapid gas chromatography-flame photometric detection (GC-FPD) method was developed for the determination of 12 organophosphorus pesticides (OPPs) in Salvia miltiorrhizae by using ultrasonication assisted one-step extraction (USAE) without any clean-up steps. Some crucial parameters such as type of extraction solvent were optimized to improve the method performance for trace analysis. Any clean-up steps were negligent as no interferences were detected in the GC-FPD chromatograms for sensitive detection...

Herein, an accurate and reliable isotope-labelled internal standard method was developed and validated for simultaneous determination of three polar pesticide adjuvants, namely 2-pyrrolidone, N-methyl-2-pyrrolidone, and N-ethyl-2-pyrrolidone in plant-derived agro-products. Matrices, including apple, cabbage, tomato, cucumber, rice, and wheat were extracted with a modified quick, easy, cheap, effective, rugged, and safe "QuEChERS" method and purified with a new clean-up sorbent (Z-Sep). A hydrophilic interaction liquid chromatography column (HILIC), exhibiting a lipophilic-hydrophilic character, was used to separate the three analytes over 10min using liquid chromatography-tandem mass spectrometry (LC-MS/MS)...

An enzymatic pool from the Amazonian bacterium Bacillus sp. P7 was used as milk coagulant. Discovery of novel coagulants is of great interest in dairy industry for the development of new textures in cheese. Color, mechanical and microstructural characterization of milk gels induced by the bacterial enzymatic pool was carried out. Effect of mineral fortification on these characteristics was studied. Whiter gels with smaller pore diameters were obtained in the presence of Ca(2+) or Mg(2+). These characteristics seemed to be influenced by the effect of ionic strength on casein structure which was also evidenced by digital texture features analysis...

Dietary eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) may have a role in contributing to the prevention or inhibition of some malignancies. DHA, the most important polyunsaturated fatty acid (PUFA) in fish and thraustochytrid oils, is known for its anticancer activity. However, antigastric cancer activity of thraustochytrid microbial oil is still unclear. In this investigation, 45 thraustochytrid strains were screened for the production of antigastric cancer oil. Cytotoxicity of 12 thraustochytrid oils was assessed by 3-(4,5-dimethythiazol- 2-yl)-2,5-diphenyl tetrazolium bromide (MTT) on gastric cancer AGS cells...

Iron deficiency is a major problem in both developing and developed countries, and much of this can be attributed to insufficient dietary intake. Over the past decades several measures, such as supplementation and food fortification, have helped to alleviate this problem. However, their associated costs limit their accessibility and effectiveness, particularly amongst the financially constrained. A more affordable and sustainable option that can be implemented alongside existing measures is biofortification...

Vitamin D deficiency occurs all over the world, mainly in the Middle East, China, Mongolia, and India. This article focuses on the vitamin D status in adults. Risk groups include older persons, pregnant women, and non-Western immigrants. Adequate vitamin D status, defined as serum 25-hydroxyvitamin D greater than 50 nmol/L, is present in less than 50% of the world population, at least in winter. Preventative strategies, such as increasing fish consumption, fortification of foods, use of vitamin D supplements, and advice for moderate sunlight exposure, are warranted...

BACKGROUND: The limited integration of ethics in nutrition-related public health policies and interventions is one major concern for those who have the task of implementing them. Ethical challenges that are overlooked during the development of such interventions could raise serious ethical issues during their implementation and even after. As a result, these decision makers need technical support and ethical guidance for adaptation of interventions to local (cultural, social, economic, etc...

Daniela Paganini, Michael B Zimmermann
In infants and young children in Sub-Saharan Africa, iron-deficiency anemia (IDA) is common, and many complementary foods are low in bioavailable iron. In-home fortification of complementary foods using iron-containing micronutrient powders (MNPs) and oral iron supplementation are both effective strategies to increase iron intakes and reduce IDA at this age. However, these interventions produce large increases in colonic iron because the absorption of their high iron dose (≥12.5 mg) is typically <20%. We reviewed studies in infants and young children on the effects of iron supplements and iron fortification with MNPs on the gut microbiome and diarrhea...

Bo Lönnerdal
The provision of iron via supplementation or the fortification of foods has been shown to be effective in preventing and treating iron deficiency and iron deficiency anemia in infants and young children. However, iron is a pro-oxidative element and can have negative effects on biological systems even at moderate amounts. An increasing number of studies have reported adverse effects of iron that was given to infants and young-children populations who initially were iron replete. These effects include decreased growth (both linear growth and weight), increased illness (usually diarrhea), interactions with other trace elements such as copper and zinc, altered gut microbiota to more pathogenic bacteria, increased inflammatory markers, and impaired cognitive and motor development...
