The importance of immunity need not be said. It may be more concerned about how to improve immunity. There are many ways to do this, such as ensuring sleep, exercising, drinking plenty of water, and so on. However, Xiao Bian's main introduction today is to improve immunity through food. Which foods have this effect?

First, protein-rich foods

Proteins constitute the basic components of leukocytes and antibodies. If the intake is insufficient, the production of lymphocytes will be reduced, which will seriously affect the immune function. Therefore, if you want to improve immunity, you should eat more high-protein foods. For example: livestock, beef, mutton, poultry, chicken, duck, fish, eggs, milk and dairy products.

Second, foods rich in vitamins

Vitamin A is related to the integrity of cells. It can prevent cells from being oxidized, protect the size of the thymus and spleen, and maintain the vitality of immune cells. Egg yolk, milk, cod liver oil, animal liver, carrot, pumpkin, leeks, pineapple, leeks and other foods can provide the body with direct or indirect supply of vitamin A in sufficient quantities.

Vitamin C can promote the immune system, increase the ability of white blood cells to phagocytose bacteria, enhance the efficacy of the thymus and lymphocytes, and can increase the level of interferon in the blood to fight against destructive molecules. Therefore, eating foods rich in vitamin C can improve immunity. Cherries, guava, kumquats, lemons, kiwis, green peppers, spinach, and tomatoes are good sources of vitamin C.

Vitamin E is the killer of free radicals. In addition, it also promotes antibody production, fights viral oxidation, and enhances immune cell function. Common foods rich in vitamin E are soybeans, milk, apricots, walnuts, sunflower seeds, malt, and spinach.

The vitamin B group is associated with the production of antibodies and white blood cells. The lack of such substances will reduce the production of lymphocytes and antibodies, and may also cause atrophy of the thymus. Since such foods are so important, why not eat more? The foods that can provide vitamin B group include animal liver, fresh meat, green leafy vegetables, whole grains, beans, nuts, bananas, and tomatoes.

Third, mineral-rich foods

The impact of minerals on human immunity is also very large. Iron deficiency will lead to decreased phagocytic ability and activity. Zinc deficiency will cause thymus atrophy. Copper deficiency will reduce the production of antibodies. Mg deficiency will affect the function of T cells and B cells. Selenium deficiency will prevent the body from inhibiting virus deformation and prevent The ability of the virus to infect is declining... Therefore, to improve immunity, you should also regularly eat animal-rich foods such as liver, lean meat, fish, shrimp, oysters, spinach, pumpkin, garlic, and fruit juices.
