Nutrigenomics is the study of how constituents of the diet interact with genes, and their products, to alter phenotype and, conversely, how genes and their products metabolise these constituents into nutrients, antinutrients, and bioactive compounds. Results from molecular and genetic epidemiological studies indicate that dietary unbalance can alter(More)
BACKGROUND Carotenoids contribute to the beneficial effects of fruits and vegetables consumption; however, the bioavailability of these compounds from fresh or processed foods is not well established. AIM OF THE STUDY We evaluated the bioavailability of beta-carotene (15 mg) from a single meal composed of cooked, pureed carrots and compared it to raw,(More)
We tested the hypothesis that some cereal-product vehicles may reduce fortificant bioavailability below 85% and examined the feasibility of using single dose, dual-label, non-saturation protocols for studying bioavailability based on urinary excretion ratios (UER; % oral 13C6 isotope dose excreted in intact folate/% i.v. 2H4 isotope dose excreted).
