1. protein

protein is the basic element of human cells, and it is also the main component of white blood cells and antibodies. If the body is seriously short of protein, it will reduce the number of lymphocytes, resulting in a serious decline in immune function. Therefore, eating more foods with high protein content, such as fresh meat, chicken, duck, fish, eggs, milk and dairy products, and abundant animal protein, can help you improve your immunity. It is suggested that drinking one or two cups of milk a day and maintaining proper intake of protein can keep your body's basic defense ability!

2. Vitamin A

Vitamin A is related to the integrity of cells, which can help cells to resist oxidation. If the body lacks vitamin A, the volume of thymus and spleen will shrink, and correspondingly, the vitality of natural killer cells will also decrease. Therefore, taking enough vitamin A can enhance the vitality of immune cells and increase the number of immune cells.

III. Vitamin C

Vitamin C can promote the immune system, increase the ability of white blood cells to phagocytose bacteria, enhance the ability of thymus and lymphocytes, help the human body increase the resistance content and increase the content of interferon in the blood. It is an effective antioxidant and can resist destructive molecules. It is one of the vitamins that enhance immunity. Vegetables and fruits rich in vitamin C, such as apples, lemons and oranges, are all good food sources to enhance immunity.

IV. Vitamin E

Vitamin E is the nemesis of free radicals, and it can also promote the production of antibodies. From the point of view of anti-virus, it has antioxidant effect and enhances the function of immune cells. In general, beans, wheat germ, fruits and vegetables, vegetable oil and drupe contain more vitamin E. However, due to the change of modern people's eating habits and unbalanced diet, the content of vitamin E that can be taken from food is very low. If you are worried about the recent epidemic of SARS, you can make more use of nutritional supplements to supplement the vitamin E that your body needs.

V. Vitamin B group and minerals

Vitamin B group is related to the production of antibodies, white blood cells and complements in the body. Lack of vitamin B group will affect the number of lymphocytes and the production of antibodies, and it will also cause the atrophy of thymus. Vitamin B group mainly exists in milk, fresh meat, green leafy vegetables, whole grains and other foods, so people with weak immunity can take more of this kind of food and enhance their own immunity. In addition, minerals are also one of the important roles that affect human immunity.

Lack of "iron" will reduce the ability and activity of phagocytes;

Lack of "zinc" will cause thymus atrophy and reduce the ability to destroy cells; Lack of "copper" will affect the production of antibodies.

Magnesium can improve the functions of T cells and B cells.

"Selenium" can reduce the deformation of virus, prevent virus infection and improve the ability of immune cells.

6. Eat more garlic

Garlic has the functions of antioxidation, enhancing immunity and antivirus, inhibiting cytomegalovirus, promoting the transformation of T lymphocytes, increasing the activity of white blood cells and macrophages, delaying and partially inhibiting the synthesis of bacterial DNA and protein, achieving antibacterial and bactericidal effects, and preventing and treating various infectious diseases.

Therefore, if you can eat garlic every day, the amount of about two garlic cloves can not only enhance immunity to prevent illness, but also reduce the chance of death due to SARS.

< < code of living for enhancing immunity > >

code 1: balanced nutrition

To eat healthy, and then enhance the body's immunity, the most important thing is adequate and balanced nutrition, which is the most often overlooked and most difficult thing for modern people to do. For most people, the first consideration is whether it is inconvenient, whether they are full or not, and whether they are delicious or not. Only a few people will give priority to "balanced nutrition".

The principle of balanced nutrition is actually very simple. Take in about three to six servings of staple food, two cups of milk, four to five servings of eggs, fish and beans, at least three servings of vegetables (preferably dark green vegetables), two servings of fruits and two to three tablespoons of oil every day. Especially for most people, the intake of vegetables and fruits is obviously insufficient, and sometimes they can't even get a portion. Therefore, we should remind ourselves that we must eat vegetables and fruits at every meal and have a diversified diet, and don't always eat certain foods, which is easy to make nutrition go to waste.

Rule 2: Drink more water, exercise more and have more rest

Drink more water: it can promote metabolism in the body, so adults must consume about 2~25 ml of water every day.

Exercise more: Do aerobic exercise for at least 3 minutes every day, such as walking, swimming or riding a bicycle. Only by maintaining a healthy body and an ideal weight can you have sufficient vitality to fight the virus!

Get more rest: Going to bed early and getting up early seems to be a fantasy for people with modern diversified nightlife. More and more people stay up late, work overtime, surf the Internet or enjoy nightlife. However, staying up late will lead to lack of sleep, resulting in a decline in immunity. Therefore, you should sleep when you should sleep, get up when you should get up, conform to the physiological clock of the human body, and get enough sleep and rest, so as to maintain your body's immunity and fight against viruses!

Rule 3: Eat less sweets, less fat and less alcohol.

Food is like a knife that can save people and kill people. Therefore, people are reminded that it is best to eat less foods that will reduce immunity, otherwise it will not only interfere with the vitality of immune cells, but even inhibit the formation of lymphocytes and damage immune function.

Eat less sweets: sweets will affect the production and activity of white blood cells and reduce the body's ability to resist diseases. Therefore, Professor Xie Mingzhe emphasized: "Don't gamble on your health because of a temporary appetite, it is very unworthy!

less fat: eating too much oil, especially taking too much bad fat, will hinder the immune ability and make immune cells in the body lazy and unable to function. Therefore, it is suggested to reduce the amount of cooking oil and the intake of high fat and salt, especially the fried things and fat meat.

drink less: drinking will seriously weaken the normal function of various immune cells, and also affect the function of liver and pancreas. Besides alcohol, cigarettes, coffee, drugs, etc., will not only reduce human immunity, but also be harmful to human body, so refusing to associate with these things is definitely the best policy. As the old saying goes, "Laughing cures all diseases", facing life with a positive outlook on life, moderately relieving stress, getting closer to nature and smiling more are excellent partners of various methods to enhance immunity!
