1. Foods with high iron content include pig liver, pig blood, lean meat, fungus, red dates and spinach. The highest iron content in animal foods is pig liver, followed by fish, lean pork, beef and mutton. Among plant foods, soybean has the highest content.

2. Fruits with high iron content include cherries, grapes and peaches. Eating meat and vegetarian food together can promote the absorption of iron, especially fruits and vegetables containing vitamin C can improve the absorption of iron. Duck blood soup, egg yolk, lean meat, beans, spinach, amaranth, tomatoes, red dates and other foods are high in iron and can be eaten often. For anemia above moderate level, oral iron therapy is also very necessary.

3. Fresh vegetables with high iron content include Philippine cuisine, shepherd's purse and celery. Because iron in food is not easily absorbed, it is necessary to take vitamin E at the same time.

Peaches, bananas, walnuts and red dates are also rich in iron. The iron content of auricularia auricula in other foods is also quite high, and kelp, seaweed and mushrooms are not small. The iron content in human milk and milk is low.

The role of iron:

1. There are about 4-5 grams of iron in adults, of which 72% is hemoglobin, 3% is myoglobin, 0.2% is in the form of other compounds, and the rest is reserve iron. Reserve iron accounts for about 25%, which is mainly stored in liver, spleen and bone marrow in the form of ferritin. Adult intake is10-15 mg. Pregnant women need 30mg.

2. 1 month, women lose about twice as much iron as men, and need copper, cobalt, manganese and vitamin C to absorb iron.

3, people in need: women, especially pregnant women need to supplement iron, but it should be noted that women who consume too much iron during pregnancy will cause fetal iron poisoning. If you are taking anti-inflammatory drugs or must take aspirin every day, then you need to supplement iron. People who often drink black tea or coffee should pay attention to that drinking a lot of black tea and coffee will hinder the absorption of iron.

4. iron is an indispensable raw material for synthesize hemoglobin ratio in that process of red blood cell maturation. After iron enters the bone marrow, it is first adsorbed on the nucleated erythrocyte membrane, and then the mitochondria entering the cell combine with porphyrin to form heme, and heme combines with globin to form hemoglobin. When iron is deficient, hemoglobin synthesis decreases, and DNA synthesis is normal at this time, which has little effect on the division and proliferation of red blood cells. The number of red blood cells in the blood does not change much, but the content of hemoglobin is low and the volume of red blood cells is reduced, which can introduce iron deficiency anemia.

5. Iron can be reused during metabolism. Except for intestinal secretion and excretion and exfoliation of skin mucosa epithelium (1mg/ day), almost no other routes lose iron.
