When it comes to iron deficiency in children, we will definitely think of spinach at the first time. Although spinach is a typical food with high iron content, the iron content that can be absorbed by human body with spinach is really very small. Eating spinach can supplement a small amount of iron. It is not the ingredients with high iron content that can supplement iron to the human body well. I only add a little iron to the human body. Moreover, spinach itself has a high oxalic acid content. After use, the combination of oxalic acid and calcium will form relatively insoluble calcium oxalate, and then form stones. Oxalic acid is an interfering factor of iron absorption, and it is easy to combine with iron to form a precipitate, but iron cannot be dissolved and absorbed in the intestine. If there is no way to remove a large amount of oxalic acid from air conditioning, then spinach can be subsidized, which is counterproductive. It is suggested that spinach should be blanched as much as possible before use, so that most oxalic acid can be eliminated. In fact, eating more spinach has many benefits. Carotene contained in spinach can be converted into vitamin A in human body, which can maintain normal vision and the health of epithelial cells, increase the ability to prevent infectious diseases and promote the growth and development of children. Spinach extract can promote the proliferation of cultured cells, resist aging and enhance youthful vitality. In our country, people mash spinach to get juice, wash their faces several times a week and use it continuously for a period of time, which can clean skin pores, reduce wrinkles and spots and keep skin smooth. Spinach itself has high nutritional value, so the cooking time of spinach should not be too long Folic acid is one of the most unstable vitamins. Most vegetables in late spring and early summer are fresh and tender, and they can get good taste without long-term cooking, which can solve the problem of folic acid loss caused by long-term cooking.

If you want to supplement iron, you should eat more iron-rich foods such as animal liver, lean meat, egg yolk and animal blood. Also pay attention to eat more foods rich in vitamin C such as fruits and vegetables, and foods rich in copper such as beef, chicken and peanut butter, which can promote the absorption of iron by the human body. Because vitamin C can promote the body's absorption of iron, when you want to supplement iron, you should not only eat more foods rich in iron, but also pay attention to eating foods rich in vitamin C, such as kiwi, Chinese cabbage, cucumber and other fresh fruits and vegetables, which can improve the body's absorption rate of iron.
