Iron deficiency anemia can eat eel. Iron deficiency anemia is mainly manifested as fatigue, dyspnea, pallor, lower limb edema, menstrual disorders, irritability, lack of concentration, xenophagia, tongue irritation, spoon-shaped nails and so on. The diet of patients with iron deficiency anemia can be supplemented with high-protein foods, such as fish, lean meat, eggs, milk, iron-rich foods such as seaweed, and foods rich in vitamin B12, such as liver, eggs, milk and so on. The protein content of eel is about 19%, which is a very high value among fish, while the fat percentage is very low. Eel is also rich in DHA and lecithin, which are the main components that make up the cell membranes of human organs and tissues. Eel contains a large amount of vitamin B12, which has the effect of preventing anemia caused by the reduction of red blood cells and has the effect of maintaining nerve function and repairing damaged peripheral nerves. If iron deficiency anemia occurs, it is recommended to go to the hospital in time for early and regular treatment. Food is not a substitute for medicine.
