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, the content of soybean is the highest.

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

3. Fresh vegetables with higher iron content are Philippine vegetables, shepherd's purse, celery, etc. Because iron in food is not easy to absorb, it is necessary to take vitamin E at the same time.

4. 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 very 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. Within 1 month, women lose about twice as much iron as men, and they 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 taking too much iron during pregnancy will cause iron poisoning in the fetus. 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 note 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 first adsorbs on the nucleated erythrocyte membrane, then enters the mitochondria in the cell and combines 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 erythrocytes. The number of erythrocytes in the blood has little change, but the hemoglobin content is low and the volume of erythrocytes is reduced, so iron deficiency anemia can be introduced.

5. Iron can be used repeatedly during metabolism. There is almost no other way to lose iron except intestinal secretion and excretion and exfoliation of skin and mucosa epithelium (1mg/ day).
