Iron in food mainly exists in the form of heme iron and non-heme iron.
1. Heme iron is the iron contained in pig liver,滋補調理， pig blood and animal food. It combines with porphyrin in hemoglobin and myoglobin and can be directly absorbed by intestinal mucosal epithelial cells, so the absorption rate is high, generally up to 20%～30%.
2. The iron in plant foods is non-heme iron, which mainly exists in the form of iron hydroxide complex, which needs to be reduced to divalent iron ions in the duodenum before it can be absorbed. 3. Vitamin C, certain amino acids, fructose, etc. in food can promote the reduction of non-heme iron to divalent iron, and combine with it to form a soluble chelate, so that the iron can be dissolved under high pH conditions, which is beneficial Because of the absorption of iron.
However, phosphate, phytic acid, oxalic acid, egg yolk, high-phosphorus protein and non-heme iron in grains, vegetables, eggs and other foods form insoluble iron salts and hinder iron absorption.
Vitamin A, Vitamin E and Vitamin B2 are beneficial to the absorption of iron.
Iron-deficiency anemia patients often develop with vitamin A deficiency at the same time that companies exist, and vitamin A deficiency is supplemented with vitamin A. Even if the iron intake remains unchanged, the nutritional health of iron will be improved. 6. Too much dietary fiber can affect the absorption of iron, but certain cellulose and beet fiber do not seem to inhibit the absorption of iron.
