Patients with anemia had better not drink tea, especially patients with iron deficiency anemia, because tea contains a substance called ellagic acid, which can combine with iron, resulting in iron absorption disorders in the gastrointestinal tract, if you drink tea, the absorption rate of iron contained in food will be reduced, eventually causing iron deficiency anemia to worsen. In addition to not drinking tea, patients with iron deficiency anemia should also eat more iron-rich foods in their daily diet, such as animal liver, animal blood, purple cabbage, black fungus, shiitake mushrooms and other foods, which are rich in iron, and by eating more of these foods, they can improve the absorption rate of iron and improve the symptoms of iron deficiency anemia. If the anemic symptoms are more serious, you can take iron supplementation drugs for treatment, commonly used are two-dimensional ferrous iron, three-dimensional ferrous iron, etc.
