Anemia has many dietary taboos. People with anemia should never touch the following seven foods, otherwise it will aggravate anemia. First, anemia can't drink coffee. Because polyphenols in coffee can form insoluble salts with iron and inhibit the absorption of iron, it is very unsuitable for anemia patients. If you want to drink, you'd better change your coffee to orange juice. Second, anemia can't drink tea. Because tannic acid and iron in tea form insoluble iron tannic acid in digestive tract, it will inhibit the absorption of iron. Moreover, iron tannin can not be absorbed by intestinal mucosal epithelial cells, which hinders the absorption of iron. Iron deficiency in human body will reduce the synthesis of hemoglobin in the body and aggravate anemia symptoms. Third, anemia cannot eat high fat, and eating too much fat will inhibit the hematopoietic function of the human body. At the same time, too much fat also affects the digestion and absorption of anemia patients.
