Iron absorption is increased by the following factor in diet:
Correct Answer: Vitamin-C
Description: In a vegetarian diet, nonheme iron is absorbed very poorly because of the inhibitory action of a variety of dietary components, paicularly phosphates, phytates and high fibre content. Ascorbic acid and meat facilitate the absorption of nonheme iron. Ascorbate forms complexes with and/or reduces ferric to ferrous iron. Meat facilitates the absorption of iron by stimulating production of gastric acid; other effects also may be involved. Either of these substances can increase availability several fold.
