What should men eat to improve immunity?

Many people may think that men do not need to improve their immunity because their immunity is much better than that of women. But in fact, after middle age, men's physical health will weaken and may even cause some men's diseases. At this time, it is absolutely necessary to improve their immunity. In this way, it can effectively prevent the occurrence of some diseases. However, if you want to improve immunity, you must first start with diet.

Yogurt. Yogurt contains probiotics, which protect the intestines and prevent the production of pathogenic bacteria. In addition, the lactic acid bacteria contained in some yogurts can promote the growth of white blood cells in the blood.

Sweet potatoes. The skin is also a member of the human immune system and is the first barrier for the human body to resist external invasions such as bacteria and viruses. Vitamin A plays an important role in the process of skin tissue bonding. The best way to supplement vitamin A is to obtain beta-carotene from food. Sweet potatoes are the fastest way to obtain this nutrient. They are rich in beta-carotene and low in calories.

Tea. Immunologists at Harvard University found that people who drank five cups of black tea a day for two weeks produced a large amount of antiviral interferon in their bodies, which was 10 times that of people who did not drink tea. This protein that can resist infection can effectively help the human body resist influenza. At the same time, it can also reduce the symptoms of food poisoning, wound infection, beriberi and even tuberculosis and malaria. Of course, drinking green tea has the same effect.

Chicken soup. The cysteine ​​released by chicken during cooking is very similar to acetylcysteine, a drug used to treat bronchitis. Salty chicken soup can reduce the symptoms of phlegm because it is similar to the ingredients in cough medicine. Adding onions and garlic to the chicken soup can make the effect more significant.

Beef. Zinc is very important in the diet. It can promote the growth of white blood cells, thereby helping the human body to defend against harmful substances such as viruses and bacteria. Even a slight zinc deficiency will increase the risk of infectious diseases. Beef is an important source of zinc for the human body, so in winter, eating beef appropriately can not only resist the cold but also prevent influenza.

Even the tea we drink often has a certain effect of improving immunity, especially black tea. If you can drink five cups of black tea a day, your body will form a lot of virus-resistant substances, even five times as much as people who don't drink tea. In this way, you can help your body resist the occurrence of influenza and reduce the toxins in the food you eat every day.
