Micronutrient deficiencies are prevalent worldwide and have detrimental effects on human health. Complex interactions between micronutrients and other dietary components largely determine micronutrient bioavailability, and understanding these interactions ...
An update on in vitro methods employed to assess iron bioavailability is presented. Solubility and dialyzability are not useful predictors of iron absorption, whereas Caco-2 cell models provide useful comparisons on the availability of iron from different ...
Carotenoid bioavailability is influenced by a number of factors including the presence of other carotenoids, which may enhance or inhibit the transport of one another by intestinal cells. Therefore, the objectives of the present study were: first, to ...
We studied the effect of some mineral waters and some of their constituents on the apical uptake of 14C-butyrate (14C-BT) and 3H-O-methyl-D-glucose (3H-OMG) by Caco-2 cells. Uptake of 14C-BT increased after a 20-minute exposure to 1 % (v/v) distilled ...
Studies on human subjects have shown that calcium (Ca) can inhibit iron (Fe) absorption, regardless of whether it is given as Ca salts or in dairy products. This has caused concern as increased Ca intake commonly is recommended for children and women, the ...
The Caco-2 cell model is widely used to assess the bioaccessibility/availability of iron from foods and diets. Analysis of iron uptake in this human epithelial cell line is usually preceded by a two-step digestion to simulate the conditions in the stomach ...
