This review explores contemporary ideas about the relationship between light exposure and vitamin biology. Nutritional biochemistry has long recognized the relationship between vitamins A and D and light exposure, but in recent years other vitamins have also been implicated in photoresponsive biological mechanisms that influence health, well-being, and even evolutionary processes. Interactions between light and vitamins can modify genotype-phenotype relationships across the life cycle, providing a basis for interesting new explanations relevant to wide aspects of human biology...

Thiamine (vitamin B1) is an essential vitamin found in most food products in developed nations. Deficiencies in this crucial vitamin lead to diseases related to nutritional needs, metabolic demands, enzymatic function, and neurological inflammation. We present an 18-year-old patient with a history of nasopharyngeal carcinoma and total parenteral nutrition (TPN) dependence who experienced neurological manifestations and heart failure, likely due to underlying thiamine deficiency, dehydration, and vasodilation...

'Hidden hunger' involves insufficient intake of micronutrients and is estimated to affect over two billion people on a global scale. Malnutrition of vitamins and minerals is known to cause an alarming number of casualties, even in the developed world. Many staple crops, although serving as the main dietary component for large population groups, deliver inadequate amounts of micronutrients. Biofortification, the augmentation of natural micronutrient levels in crop products through breeding or genetic engineering, is a pivotal tool in the fight against micronutrient malnutrition (MNM)...

A constellation of metabolic disorders, including obesity, dysregulated lipids, and elevations in blood glucose levels, has been associated with cardiovascular disease and diabetes. Analysis of data from recently published genome-wide association studies (GWAS) demonstrated that reduced-function polymorphisms in the organic cation transporter, OCT1 (SLC22A1), are significantly associated with higher total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglyceride (TG) levels and an increased risk for type 2 diabetes mellitus, yet the mechanism linking OCT1 to these metabolic traits remains puzzling...

Aquatic environments contain large communities of microorganisms whose synergistic interactions mediate the cycling of major and trace nutrients, including vitamins. B-vitamins are essential coenzymes that many organisms cannot synthesize. Thus their exchange among de-novo synthesizers and auxotrophs is expected to play an important role in the microbial consortia and explain some of the temporal and spatial changes observed in diversity. In this study, we analyzed metatranscriptomes of a natural marine coastal microbial community, diel sampled quarterly over one year to try to identify the potential major B-vitamin synthesizers and consumers...

Sugar-containing beverages are often seen as a negative influence on diet quality and body weight control. The present study examines the consumption of 100% fruit juice (FJ) based on a seven-day dietary survey in a representative sample of French adults ( n = 1607). About a half of the participants (44%) consumed FJ, most often at breakfast time (60%). Average intake in FJ consumers was 115.6 ± 4.0 mL/day (46.3 ± 1.7 kcal/day). Prevalence of consumption increased with education and income and decreased with age, but no association was observed with body mass index (BMI), physical activity, or smoking...

Thiamine is a highly hydrophilic vitamin which is insoluble in common organic solvents, utilized traditionally for synthesis of molecularly imprinted polymer. In this work a simple strategy is introduced to overcome the insolubility problem of thiamine and prepare an efficient MIP in chloroform. Thiamine, as a cationic agent, involved in an ion-pair complex with anionic species of trimethylsilyl-propane sulfonate (TPS). The ion-pair was then transferred effectively to apolar solvent of chloroform where the polymerization reaction was conducted to produce nano-sized thiamine imprinted polymer...

BACKGROUND: 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. METHODS: This was a secondary analysis of nutrition data collected during a randomized, controlled trial...

Non-alcoholic fatty liver disease (NAFLD) is becoming a major health burden with increasing prevalence worldwide due to its close association with the epidemic of obesity. Currently there is no standardized pharmacological treatment, and the only proven effective therapeutic strategy is lifestyle modification, therefore it is important to determine the potential dietary targets for the prevention and treatment of NAFLD. We assessed nutritional status in 30 patients diagnosed with NAFLD using anthropometric parameters, hand grip strength, and lifestyle and dietetic parameters (physical activity, NRS2002 form and three-day food diary)...

Thiamin (vitamin B1) is a cofactor required for essential biochemical reactions in all living organisms, yet free thiamin is scarce in the environment. The diversity of biochemical pathways involved in the acquisition, degradation, and synthesis of thiamin indicates that organisms have evolved numerous ecological strategies for meeting this nutritional requirement. In this review we synthesize information from multiple disciplines to show how the complex biochemistry of thiamin influences ecological outcomes of interactions between organisms in environments ranging from the open ocean and the Australian outback to the gastrointestinal tract of animals...
