The dietary plan for patients with iron-deficiency anemia first involves increasing the intake of iron-rich foods, such as animal liver, blood, soybeans, black fungus, sesame paste, brown sugar, lean meat, egg yolks, pork and lamb kidneys, and dried fruits. Second, it is recommended to appropriately supplement with vitamin C, as taking iron supplements and vitamin C together can increase iron absorption, thereby achieving better iron supplementation effects. Thirdly, patients are advised to change their dietary habits to increase the intake and bioavailability of nutrients like vitamin A, vitamin B2, folic acid, and vitamin B12, which are involved in the production of red blood cells. Supplementing these nutrients can also enhance the utilization of iron from food, thereby assisting in the treatment.
