1, intake of high iron food. Meat (especially red meat), poultry, fish in only 40% can be absorbed, eggs, cereals, nuts, beans and other vegetables with high iron absorption rate is absorbed only less than 10%, and spinach can only absorb about 2%. Iron-rich foods are kelp, lobster, nori, fungus, mushrooms, beans and their products, meat, eggs, chicken blood, duck blood, pig blood, etc. Oral iron supplements such as ferrous sulfate, ferrous fumarate, ferrous glucose, ferric ammonium citrate, etc. The dose is calculated as elemental iron 6mg/kg per day. iron fortified foods such as flour, salt, soy sauce, etc. can also be used. Those with severe gastrointestinal reactions to oral iron can be switched to intramuscular iron dextran injection. Continue to take small doses of iron for 3-6 months after the anemia is corrected to replenish iron reserves. 2. Give a high-protein diet to promote iron absorption, which also provides the raw materials necessary for hemoglobin synthesis in the body. Eat more foods rich in vitamin C, such as, fresh dates, kiwi, citrus, tomatoes, etc. When there is difficulty in supplying foods rich in vitamin C, vitamin C preparations can be given appropriately to promote the absorption and utilization of iron. Simultaneous intake of vitamin C-rich lemon juice, orange juice and iron-rich vegetables can increase the absorption rate of iron from vegetables by 2-3 times. If you supplement iron preparations at the same time, you can also take it at the same time as vitamin C. 3, infants, especially premature babies and twins should be supplemented with iron-rich foods, such as broth, liver puree, eggs, soybean products and green leafy vegetables in a timely manner. Pregnant women and lactating mothers should be supplemented with sufficient amount of iron to ensure that they can consume 12-15mg of iron per day. 4. Avoid taking calcium, zinc preparations, antacids and iron preparations at the same time. In addition, phosphorus, inositol hexaphosphate and oxalic acid in food also affect the absorption of iron. Phosphorus-rich foods include almonds, whole grains, cheese, cocoa, brain marrow, liver and kidney, milk, peanuts, etc. Foods rich in inositol hexaphosphate include wheat germ, peanuts, almonds, walnuts, soybeans, etc. Foods rich in oxalic acid include coffee, tea, cocoa, green beans, etc. Avoid taking iron supplements with tetracycline at the same time. 5, prevention of pediatric iron deficiency anemia should start from the fetal period, giving a negative diet should give enough iron. Breastfeeding is advocated for at least 4 months, during which time no fixed food is added, and iron supplementation is started after 4 months. Iron fortification prescriptions are appropriate for artificial feeders. Pay attention to dietary arrangements during early childhood to ensure adequate animal protein and legumes. Correcting bad eating habits, such as long-term vegetarianism, partial eating, and picky eating, etc., and reasonable diet and nutrition can effectively prevent the occurrence of iron deficiency anemia. 6.Improve cooking techniques and promote the use of iron cookware.
