Efficacy of B12 Fortified Nutrient Bar and Yogurt in Improving Plasma B12 Concentrations-Results From 2 Double-Blind Randomized Placebo Controlled Trials

Functional yogurt, enriched and probiotic: A focus on human health

The food industry has always sought to produce products enriched with vitamins, probiotics, polyphenols, and other bioactive compounds to improve physiological function, enhance nutritional value, and provide health. These compounds are essential for human health, and their deficiency can lead to adverse effects. Therefore, food enrichment is an important strategy to improve the nutritional value and, in some cases, improve the quality of food. Recently, functional foods have been very popular around the world. Among food products, dairy products constitute a major part of people's diet, and due to the high consumption of dairy products, including yogurt, the enrichment of this product effectively reduces or prevents diseases associated with nutritional deficiencies. Most consumers generally accept yogurt due to its high nutritional value and low price. So, it can be considered a good candidate for enrichment with micronutrients and probiotics. In recent years, using functional foods to prevent various diseases has become a popular topic for research. In this study, the effect of fortified yogurt in preventing diseases and improving deficiencies has been investigated, and it has been proven that super healthy yogurt has a positive effect on human health.

Pre-conceptional Maternal Vitamin B12 Supplementation Improves Offspring Neurodevelopment at 2 Years of Age: PRIYA Trial

Background: The first thousand days window does not include the pre-conceptional period. Maternal pre-conceptional health has a profound influence on early embryonic development (implantation, gastrulation, placentation etc). Nutrition provided by B-complex vitamins is important for fetal growth, especially neural development. We report effects of a maternal pre-conceptional vitamin B12 and multi micronutrient (MMN) supplementation on offspring neurodevelopmental performance. Methods: In the Pune Rural Intervention in Young Adolescents trial (PRIYA), adolescents (N = 557, 226 females) were provided with vitamin B12 (2 μg/day) with or without multiple micronutrients, or a placebo, from preconception until delivery. All groups received mandatory iron and folic acid. We used the Bayley's Scale of Infant Development (BSID-III) at 24-42 months of age to investigate effects on offspring neurodevelopment. Results: Participants had similar baseline B12 levels. The levels improved in the B12 supplemented groups during pre-conception and pregnancy (28 weeks gestation), and were reflected in higher cord blood holotranscobalamin (holo-TC) levels compared to the placebo group. Neurodevelopmental outcomes in the B12 alone group (n = 21) were better than the placebo (n = 27) in cognition (p = 0.044) and language (p = 0.020) domains (adjusted for maternal baseline B12 levels). There was no difference in neurodevelopmental outcomes between the B12 + MMN (n = 26) and placebo group. Cord blood Brain Derived Neurotrophic Factor (BDNF) levels were highest in the B12 alone group, though not significant. Conclusion: Pre-conceptional vitamin B12 supplementation improved maternal B12 status and offspring neurodevelopment at 2 years of age. The usefulness of cord BDNF as a marker of brain development needs further investigation. Our results highlight the importance of intervening during pre-conception.
