A question of balance: achieving appropriate nutrient levels in biofortified staple crops.
The biofortification of staple crops with vitamins is an attractive strategy to increase the nutritional quality of human food, particularly in areas where the population subsists on a cereal-based diet. Unlike other approaches, biofortification is sustainable and does not require anything more than a standard food-distribution infrastructure. The health-promoting effects of vitamins depend on ...
متن کاملEffect of B-complex vitamins on the antifatigue activity and bioavailability of ginsenoside Re after oral administration
BACKGROUND Both ginsenoside Re and B-complex vitamins are widely used as nutritional supplements. They are often taken together so as to fully utilize their antifatigue and refreshing effects, respectively. Whether actually a drug-nutrient interaction exists between ginsenoside Re and B-complex vitamins is still unknown. The objective of this study was to simultaneously investigate the effect o...
متن کاملAccounting for differences in the bioactivity and bioavailability of vitamers
Essentially all vitamins exist with multiple nutritionally active chemical species often called vitamers. Our quantitative understanding of the bioactivity and bioavailability of the various members of each vitamin family has increased markedly, but many issues remain to be resolved concerning the reporting and use of analytical data. Modern methods of vitamin analysis rely heavily on chromatog...
متن کاملMultivitamin and multimineral dietary supplements: definitions, characterization, bioavailability, and drug interactions.
Although multivitamins, multiminerals, and similar terms (eg, multis or multiples) are commonly used, they have no standard scientific, regulatory, or marketplace definitions. Thus, multivitamins-multiminerals refers to products with widely varied compositions and characteristics. Multivitamin-multimineral composition databases use label values as surrogates for analyzed values. However, actual...
متن کاملPotential bioavailability enhancement of bioactive compounds using food-grade engineered nanomaterials: a review of the existing evidence.
The development of engineered nanometre sized materials (ENM) produced with food-grade ingredients and designed as delivery systems for organic and inorganic materials has gained increasing interest. The major reason for this trend is the aim to overcome problems associated with the low bioavailability of many bioactive compounds (BC) which are usually claimed to benefit human health. In this r...
متن کاملVitamin D2 versus D3 – Scientific Evidences
Vitamins D3 and D2 are chemically different. In contrast to vitamin D3, vitamin D2 has a double bond between carbons 22 and 23 and a methyl group on carbon 24 in its side chain. Irrespective of their chemical differences, the human body uses the same enzymatic pathways to transform these vitamins to their pro-hormone (conditional vitamins) and hormone forms. There are ongoing debates in the lit...
