Second, high-quality protein. The immune system needs a lot of protein to synthesize antibodies and white blood cells when necessary. Protein sources that make the body in a good immune state include eggs, lean meat and bean products.
Third, almonds, malt and various dark green vegetables are rich in vitamin E.
Fourth, garlic and onions. It is found that onion can enhance the immune activity of T cells, thus enhancing the overall immune response. Foods containing immunocompetent substances similar to those in garlic and onion can play a cleaning and antiviral role in the human body, killing and removing poisons and germs.
Fifth, chicken soup. Chicken soup. Studies have proved that drinking chicken soup can prevent upper respiratory tract infectious diseases such as colds and flu. Because chicken contains many kinds of amino acids necessary for human body, it is rich in nutrition, especially cysteine, which can enhance human immunity. In addition, drinking chicken soup also has a positive effect on accelerating recovery after infection.
Sixth, * moderate * foods containing zinc. Zinc is an indispensable trace element in human body, and many enzymes in human body can only play a role together with zinc, which is very important for regulating immune function. In addition, it has another function, that is, anti-infection. Studies have confirmed that daily intake of 50 ~ 100 mg of zinc can prevent influenza. Seafood, lean meat, coarse grains and beans are all rich in zinc.
Seventh, tofu. Tofu, as a kind of food with the same origin of medicine and food, has many functions such as invigorating qi and tonifying deficiency. It was found that the calcium content of 100g tofu was 140mg- 160mg, and the protein content of tofu was relatively high in plant food, which contained 8 amino acids necessary for human body, as well as unsaturated fatty acids and lecithin which were lacking in animal food. Eating tofu regularly can protect the liver, promote metabolism, increase immunity and detoxify. But the disadvantage of tofu is that its soybean protein lacks an essential amino acid-egg acid. If you eat alone, the utilization rate of protein is low. For example, if it is matched with some other foods, it can supplement the egg amino acids lacking in soybean protein, so that the proportion of the whole amino acids tends to be balanced, and the human body can fully absorb and utilize the protein in tofu. Protein of eggs and meat has a high methionine content, so tofu should be matched with these foods, such as tofu scrambled eggs, chopped tofu, roasted tofu with sliced meat and so on. This collocation can improve the utilization rate of protein in tofu.
Eighth, mushroom food. Studies have shown that mushrooms contain 18 kinds of amino acids, more than 30 kinds of enzymes, and more vitamins A, B and D. Experiments have confirmed that "mushrooms and glucomannanase can improve the human body's ability to inhibit malignant tumors; It also contains mushroom filament cell sap and lentinan, which not only has good anti-tumor ability, but also can induce human body to produce interferon, improve immunity and resist virus invasion. In addition, the nucleic acid in Lentinus edodes can inhibit cholesterol in serum and viscera, prevent hyperlipidemia, and then prevent arteriosclerosis and vascular fragility. Mushrooms and mushrooms have similar functions, and long-term consumption can play a very good health care role. " Many people are used to using mushroom food as a seasoning for cooking, but rarely as a dish, and their intake is limited. The most ideal way to eat fungus food is to bring it into the diet structure and eat it regularly.
In addition, watermelon contains protein, zinc, selenium, vitamin E and essential fat, which can improve immunity. Eating too many sweets will reduce immunity. Eating too many sweets will consume vitamins in the body. The deficiency of some vitamins will lead to the decrease of the secretion of digestive juice such as saliva. Therefore, while supplementing the spleen artificially, Zhongyi also thinks that it is "willing to hurt the spleen". "Under normal circumstances, the average phagocytosis of a white blood cell in human blood is 14, eating a sweet steamed bread becomes 10, eating a sugary snack becomes 5, and eating a cream chocolate becomes 2. It can be seen that sweets have a certain impact on immunity. "
