Experts say that due to the presence of phosphoprotein and phosvitin in the egg yolk, it can combine with iron to form a substance that is poorly soluble and not easily absorbed. Therefore, the actual absorption rate of yolk iron is less than 3%. Calculated in this way, the baby can only absorb 0.048 milligrams of iron from an egg yolk, which is almost negligible. Infants only take iron from milk and food supplements. If they do not regularly supply iron-rich foods such as animal livers or directly add iron, it is difficult to meet the physiological needs of infants and young children. For example, the absorption rate of iron in rice is less than 1%, and that of vegetables and fruits is 5%. The absorption rate of iron in legumes is high, but it is only 7%. Milk is iron-poor food and the absorption rate is not high.
