; Pay attention to supply human body with enough hematopoietic raw materials in diet, such as iron, vitamin C, vitamin B group, protein, etc. Iron is one of the main components of hemoglobin. Iron-rich foods mainly include liver, kidney, heart and belly of animals. Kelp is rich in iron, and the iron content per100g of kelp is as high as 150 mg, which is 6 times higher than that of pig liver. Vitamin C can promote the absorption and utilization of iron. If vitamin C is lacking, no amount of iron in food will help, because vitamin C can change trivalent iron into bivalent iron. Therefore, in order to promote the absorption of iron, we should eat foods rich in vitamin C, such as fresh vegetables and fruits, especially green vegetables and vegetables with high acidity, such as tomatoes, oranges and sour hawthorn. Vitamin B (vitamin B 1 folic acid) is an essential substance for the growth and development of red blood cells. It is rich in animal liver, kidney and lean meat, and folic acid is also contained in leafy vegetables. Protein is an important raw material of hemoglobin. Anemia patients should take enough protein, such as milk, lean meat, fish, eggs, soybeans and bean products. Anemia patients often have poor appetite and indigestion. Therefore, we should pay special attention to the color, aroma, taste and shape of diet to arouse patients' appetite. In fact, well-cooked dishes can also promote gastric acid secretion.
