What should you eat to increase white blood cells and improve immunity? First, brightly colored fruits and vegetables. Sour berries, kumquats, tomatoes, carrots and spinach are rich in antioxidants, which can protect the body's immune cells from harmful factors in the environment and enhance the ability of white blood cells to kill foreign microorganisms. At the same time, because these foods also contain a large amount of vitamin C, they are helpful in resisting influenza and can help patients recover quickly. Second, high-quality protein. The immune system requires a large amount of protein to synthesize antibodies and white blood cells when necessary. Protein sources that keep the body in a good immune state include eggs, lean meat, and soy products. Third, almonds, malt and various dark green vegetables are rich in vitamin E. Fourth, garlic and onions. Studies have found that onions can enhance the immune activity of T cells, thereby improving the overall immune response. Foods containing immunoactive substances similar to those found in garlic and onions can act as cleaning and disinfectants in the human body, killing and removing toxins and germs. Fifth, chicken soup. chicken soup. Studies have shown that drinking chicken soup can prevent upper respiratory tract infections such as colds and flu. Because chicken contains a variety of amino acids necessary for the human body, it is rich in nutrients, especially the cysteine ??contained in it, which can enhance the body's immunity. In addition, drinking chicken soup also has a positive effect on accelerating recovery after infection. Sixth, *moderate* zinc-containing foods. Zinc is an indispensable trace element for the human body. Many enzymes in the human body must participate in zinc to function. Zinc is very important for regulating immune function. In addition, it has another function, which is to fight infection. Studies have confirmed that consuming 50 to 100 mg of zinc every day can prevent influenza. Seafood, lean meat, whole grains and legumes are rich in zinc. Seventh, tofu. As a food with both food and medicine, tofu has many functions such as replenishing qi and replenishing deficiency. Research has found that generally 100 grams of tofu contains 140 mg to 160 mg of calcium. Tofu is the highest in protein among plant foods. It contains 8 essential amino acids for the human body, as well as unsaturated fatty acids and lecithin that are lacking in animal foods. wait. Eating tofu regularly can protect the liver, promote body metabolism, increase immunity and have detoxification effects. However, the disadvantage of tofu is that the soybean protein it contains lacks an essential amino acid - egg amino acid. If eaten alone, the protein utilization rate is low. If it is combined with some other foods, the egg amino acid missing in the soy protein can be supplemented. By balancing the entire amino acid ratio, the human body can fully absorb and utilize the protein in tofu. The methionine content in eggs and meat proteins is high, and tofu should be mixed with these foods, such as scrambled eggs with tofu, tofu with minced meat, and roasted tofu with sliced ??meat. Eating it in this way can improve the utilization of the protein in tofu. Eighth, mushroom foods. Research shows that mushrooms contain 18 kinds of amino acids and more than 30 kinds of enzymes, as well as more vitamins A, B, and D. Experiments have confirmed that "Shiitake mushrooms also contain glucosylase, which can improve the body's ability to inhibit malignant tumors; they also contain shiitake mushroom cell fluid and lentinan, which not only have good anti-tumor capabilities, but also induce the body to produce interferons and improve the body's immunity." , resist virus invasion. In addition, the nucleic acid substances in shiitake mushrooms can inhibit cholesterol in serum and viscera, prevent and treat hyperlipidemia, and thereby prevent arteriosclerosis and blood vessel brittleness. Mushrooms have the same effect as shiitake mushrooms, and long-term consumption can have the same effect. "Many people are accustomed to using mushrooms as condiments for stir-fry dishes, but rarely as dishes, and their intake is limited. The ideal way to eat is to include fungi in your diet and eat them regularly. In addition, watermelon contains protein, zinc, selenium, vitamin E and essential fats, which can improve immunity. Consuming too many sweets can lower your immunity. Consuming too many sweets depletes your body of vitamins. The lack of certain vitamins can lead to a decrease in the secretion of digestive juices such as saliva. Therefore, while Zhongyi believes that sweetness can nourish the spleen, it also believes that sweetness can harm the spleen. "Under normal circumstances, the average ability of a white blood cell in human blood to phagocytose germs is 14. After eating a sweet steamed bun, it becomes 10. After eating a sugary snack, it becomes 5. After eating a piece of cream chocolate, it becomes 2. It can be seen that sweets have a certain impact on immunity.”
