For people who often work and study in front of the computer, drinking green tea is also a good choice, because green tea has a certain effect on radiation resistance. Eating tomatoes regularly can improve immunity. Eating leeks in early spring can improve immunity. Quitting sweets can prolong life 15 years (researchers at the German Human Nutrition Research Center found that strictly limiting sugar intake can "start the in-vivo longevity device" and prolong life by 20%, equivalent to 15 years. This is because the lack of sugar in the human body will stimulate the increase of free radicals in a short time. Although free radicals are the biggest cause of aging and diseases, this short-term increase will stimulate the human body to establish a long-term defense mechanism like a vaccine to avoid long-term damage of free radicals. Six measures to improve immunity Winter is a season of frequent diseases, especially for people who work in office buildings. Because of the different indoor and outdoor temperatures and the environmental pollution in winter, they are more prone to various diseases. Here are several simple and practical ways to improve immunity: First, sleep is closely related to human immunity through sleep. Famous immunologists found through the "self-sleep" experiment that a good sleep can significantly increase the number of two kinds of lymphocytes in the body. Research by medical experts shows that during sleep, the human body will produce a sleep factor called muramic acid, which will increase the number of white blood cells, activate macrophages, and enhance the detoxification function of the liver, thus eliminating invading bacteria and viruses. Second, maintaining an optimistic attitude can keep the human body in the best condition, especially in today's society, people are under great pressure, and great psychological pressure will lead to an increase in hormone components that inhibit the human immune system, so it is easy to catch a cold or suffer from other diseases. Third, limit drinking. Don't drink more than 65,438+000 ml of low-alcohol liquor, 250 ml of yellow wine and 65,438+0 bottles of beer every day, because alcohol will have a negative impact on every part of the human body. Even if drinking wine can lower cholesterol, it should be limited to one glass a day. Excessive drinking will do great harm to blood, heart and other organs. Four or three participating sports experts pointed out that the number of immune cells will increase and the resistance will increase relatively after exercising for 30 to 45 minutes a day, five days a week and 12 weeks. Exercise as long as your heart beats faster. Walking after meals is very suitable. V. Supplementing vitamins Appropriate supplementation of vitamins and minerals every day. Experts point out that the quantity and vitality of human body's weapons against foreign invasion, including interferon and various immune cells, are all related to vitamins and minerals. Sixth, improve the ecological environment in the body. The research and application of microecological agents to improve immunity have a long history. Studies have shown that the beneficial flora represented by intestinal Bifidobacterium and Lactobacillus has broad-spectrum immunogenicity, which can stimulate the division and reproduction of lymphocytes responsible for human immunity, and at the same time mobilize the nonspecific immune system to "eat" various pathogenic foreign microorganisms including viruses, bacteria and chlamydia, produce various antibodies, and improve human immunity. For healthy people, it is advisable to "diet" and eat more lactic acid bacteria drinks; Healthy marginal people can use microecological agents to adjust the microecological balance in the body. Foods that can improve immunity 1. Ganoderma lucidum: Ganoderma lucidum can enhance human immunity, because it contains polysaccharide with anticancer effect, and 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. References:
