Men can take iron supplements by eating iron-containing foods, and those diagnosed with iron-deficiency anemia can also take iron-containing medications as prescribed by their doctors. Iron is an important component in the formation of red blood cells, and iron deficiency anemia can occur when the body lacks iron. 1. Iron-rich food In daily life, you can eat some iron-rich foods to replenish iron. Animal food with high iron content includes animal liver, animal blood, beef jerky and so on. Pig liver contains 23.2 milligrams of iron per 100 grams, 18.3 milligrams of iron per 100 grams of sheep’s blood, 15.6 milligrams of iron per 100 grams of beef jerky, 8.7 milligrams of iron per 100 grams of pig’s blood, and 7.5 milligrams of iron per 100 grams of sheep’s liver. Among other plant foods, 283.7 mg of iron is contained in every 100 g of mossweed, 235.1 mg of iron is contained in every 100 g of red mushrooms (dried) in Puzhong, 97.4 mg of iron is contained in every 100 g of fungus (dried), 42.5 mg of iron is contained in every 100 g of dried mulberries, and 22.7 mg of iron is contained in every 100 g of black sesame seeds. Although the iron content of plant foods is higher than that of the animal foods mentioned above, it is poorly absorbed and the two can be consumed together on a daily basis. While supplementing iron-containing foods, you should also eat more fruits and vegetables rich in vitamin C. Vitamin C can promote the conversion and absorption of iron in the body. 2. Drugs for iron supplementation Men diagnosed with iron deficiency anemia can take oral folic acid, ferrous sulfate tablets and other dietary supplements as prescribed by the doctor; or ferrous sulfate succinate granules with vitamin C tablets and other drugs.
