(1) Food that can enhance immunity 1. Ganoderma lucidum: Ganoderma lucidum can enhance human immunity, because it contains polysaccharide with anticancer effect, in addition, it is rich in germanium. Germanium can accelerate metabolism, delay cell aging, and exert its anti-cancer effect by inducing human body to produce interferon; 2. Fresh radish: because it is rich in interferon inducer, it has immune function; 3. Ginseng royal jelly: it can improve the immunity and endocrine regulation ability of the body, and contains bee lactic acid with anticancer effect; 4. Mushrooms, Hericium erinaceus, Volvariella volvacea, Auricularia auricula, Tremella fuciformis, Cheyang, Lily, etc. Both of them have obvious effects of enhancing immunity; 5. Lentinus edodes: Lentinus edodes contains lentinan, which can enhance human immunity. (2) How to enhance resistance and have a good sleep. Poor sleep is related to the decline of immune system function. The body's resistance will decrease and the incidence will increase. But do you have to sleep for eight hours? Not necessarily, as long as you wake up in the morning and feel refreshed. The study of exercising for 30 minutes a day shows that the number of immune cells will increase and the resistance will be relatively enhanced if you exercise for 30 to 40 minutes a day, 5 days a week and 12 weeks. As long as the heart beats faster, walking after meals is very suitable. If it is too intense or lasts for more than 1 hour, the body will produce some hormones and inhibit the activity of the immune system. Massage can relax the body and relieve stress. It was found that after massage for 45 minutes every day for 1 month, the number of immune cells will increase and the immune function will be improved obviously. Vitamin C is 200 grams a day, and taking 200 to 500 mg of vitamin C every day helps to enhance the body's resistance. Vitamin E As long as you eat 200 international units of vitamin E every day, you can strengthen your ability to fight infectious pathogens. Don't abuse antibiotics. Abuse of antibiotics will reduce the hormones responsible for coordinating the immune system in some patients. People with more friends are less likely to catch a cold, and their immune function is 2% stronger than that of introverts. Researchers believe that good social relations help to fight stress, reduce stress hormones and affect immune cell function. However, too much contact will also become a kind of pressure, don't force yourself. Three or five intimate friends are more important than a bunch of casual acquaintances. Laughter can reduce stress hormones. In addition, the study pointed out that laughter significantly increased interferon, stimulated immune function, and immune cells became more active. If you feel that you lack humor, you can watch more comedies and funny animations, think about the plot when you are nervous, and learn to be optimistic about the status quo. Daydreaming for 5 minutes every day, while taking a deep breath, can increase the number of immune cells and even enhance the activity of cells. I believe that your optimism can keep your immune system at its best. (3) Which five foods can increase your immunity? There are five foods that you may not eat often, but they are the stars that strengthen your resistance and keep you away from diseases. Beef: not only contains enough fat and calories, but also contains a lot of zinc. Zinc contributes to the production of white blood cells and can improve the immune ability of the body, and this trace element is the most abundant in beef. An 85g serving of lean beef can provide about 30% of the daily zinc requirement. If you don't like beef, you can also try other foods rich in zinc, such as oysters, fortified whole grains, pork, poultry, yogurt, milk and so on. Tea: Free radicals are extremely destructive substances, which will damage human cells and their DNA, accelerate the aging process, and lead to cardiovascular and cerebrovascular diseases and cancer. Antioxidants are powerful weapons against free radicals. Although fruits and vegetables contain a lot of antioxidants, black tea and green tea contain more antioxidants than any other vegetables and fruits. Therefore, drinking a cup of green tea or black tea every day can get enough antioxidants, which is refreshing and healthy. Edible fungi: Since ancient times, people have known that edible fungi can enhance human immunity. Modern research results show that edible fungi can promote the production of white blood cells, enhance their vitality, and make this immune cell more aggressive to germs. Common edible fungi are: Lentinus edodes, Pleurotus ostreatus, Tricholoma matsutake, Agrocybe aegerita, Coprinus comatus, Flammulina velutipes and so on. We should include them in our three meals a day Sweet potato: Skin is also a part of human immune system. It covers an area of about 16 square foot of human body, forming the first line of defense of human body, which can prevent the invasion of pathogenic microorganisms such as bacteria and viruses. In order to keep the skin strong, we need to take enough vitamin A. One of the best ways to get vitamin A is to take it from foods containing carotene, and then the body will convert this carotene into vitamin A.. The fastest and most acceptable food to get carrots is sweet potato, which is not only rich in cellulose, but also rich in carotene. Eating sweet potatoes often can kill two birds with one stone. Yogurt: beneficial bacteria attached to human intestinal mucosa, such as Bifidobacterium, Lactobacillus acidophilus and Lactobacillus casei, can prevent harmful bacteria from invading human body through intestinal wall. Yogurt contains a lot of lactic acid bacteria. Lactic acid bacteria are intestinal scavengers, which can make beneficial changes in the composition of intestinal flora, promote the secretion of digestive enzymes and intestinal peristalsis, remove intestinal garbage and inhibit the reproduction of spoilage bacteria. Drinking 250~500 grams of yogurt every day can maintain the normal balance of intestinal flora and adjust the beneficial intestinal flora to a normal level.
