People often think that anemia means “low blood” in the body. In fact, this is incorrect. In medical terms, anemia refers to a decrease in the number of red blood cells in the blood and a low concentration of hemoglobin, causing the blood to become thin and pale. Anemia is a symptom that can be accompanied by various diseases called secondary anemia. Blood system diseases with anemia as the main manifestation include aplastic anemia, iron deficiency anemia, megaloblastic anemia, hemolytic or blood loss anemia, etc. Most anemias in middle-aged and elderly people are iron deficiency anemia and megaloblastic anemia. The causes of anemia are complex, and secondary anemia due to infection, kidney or liver diseases, tumors or chronic diseases are more common. Patients with anemia should not blindly apply blood supplementation drugs, but should be treated according to the cause of the disease. At the same time, attention to dietary regimen has good effect on the prevention and treatment of anemia. The main principle of dietary regimen for anemic patients is to provide enough hematopoietic materials to gradually restore the red blood cells and hemoglobin in the blood to normal. The substances closely related to the manufacture of red blood cells, hemoglobin and the growth and development of red blood cells are mainly protein, iron, vitamin B12, folic acid and a small amount of copper. 1, to eat more iron-rich food Iron deficiency anemia is a more common clinical anemia. Middle-aged and elderly people, whether it is hookworm intestinal bleeding, repeated multiple bleeding from the upper gastrointestinal tract, or bleeding from hemorrhoids for many years, should lead to long-term iron loss and cause iron deficiency anemia, therefore, more iron-rich foods should be consumed. Such as animal offal, egg yolk, lean meat and beans are rich in iron: vegetables such as celery, fresh bean curd, spinach, water chestnuts, taro, bean sprouts, etc. contain more iron; fruits such as hawthorn, apricot, peach, grapes, red dates, longan, etc. also have high iron content. Black fungus, nori, kelp, mushrooms, white fungus, etc. are particularly rich in iron. Therefore, anyone suffering from iron deficiency anemia can often choose to eat. 2, supply sufficient vitamin B12 and folic acid Both of these substances are indispensable in the development of red blood cells. Therefore, you should eat more food containing vitamin B12 and folic acid. Animal proteins such as liver, kidney and lean meat are rich in vitamin B12; folic acid is mostly found in green leafy vegetable tea, so as long as you pay attention to eating more animal proteins and green leafy vegetables, and drink tea appropriately, you can provide the body with the vitamin B12 and folic acid it needs. 3.Supply sufficient amount of protein and various vitamins The middle-aged and elderly intellectuals suffering from anemia should eat more protein foods with high physiological value in their diet, such as milk, egg yolk, lean meat, fish and shrimp, beans and soy products. At the same time, they should also eat more vegetables and fruits in order to make the organism take in sufficient protein and various vitamins. In addition, patients with anemia often suffer from a lack of stomach acid, which affects the digestion and absorption of iron in the stomach. Therefore, attention should be paid to providing an acidic environment for the stomach, such as eating more sour milk, sauerkraut and vinegar, etc. Since middle-aged and old-aged patients with anemia have poor appetite and poor gastrointestinal digestive function, they should pay more attention to food preparation and try to make food with good color, aroma, taste and shape to enhance appetite. For patients with poor teeth and poor digestive function, food can be processed into liver puree, minced meat, broth, egg custard, tofu brain, vegetable puree, juice, etc., so that it can be easily digested and absorbed after eating.
