Iron nutrition and absorption: dietary factors which …

Food contains more nonheme iron and, thus, it makes the larger contribution to the body''s iron pool despite its lower absorption rate of 2% to 20%. Absorption of nonheme iron is markedly influenced by the levels of iron stores and by concomitantly consumed dietary components. Enhancing factors, such as ascorbic acid and meat/fish/poultry, may ...
