What to eat to increase immunity? 1. Ganoderma lucidum: Ganoderma lucidum can enhance human immunity. This is because Ganoderma lucidum 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. Here are some simple and practical ways to improve immunity: the immune system can prevent bacteria and viruses from entering the human body and help patients recover. It is closely related to endocrine system and nervous system, and people's lifestyle and emotions directly affect immune function. Dr. Li Burke of the University of California Medical College wrote on the website of "Avatar": "Years of research show that you can live a healthy and happy life as long as you pay attention to some simple details of your life." The following are 10 scientific ways to improve immunity: First, when you are with friends, your immune system will be in a good state because you feel friendship and social recognition. To prove this, researchers at the Paris Center for Physical and Mental Health exposed participants to the cold virus, and then the researchers tracked their social activities. It turns out that people who spend more time with friends, family and colleagues are less likely to catch a cold. At the same time, physical contact such as hugging and touching can also make human immune cells more active. Second, listening to your favorite music can also activate your immune system, but it must be listening to the music you really like. "The same piece of music sounds like Yue Xian to some people and may be noise to some people." Dr. Burke said, "The key is to choose music that can soothe your heart." Good music, like food and sex, can stimulate pleasant parts of the brain, thus improving immunity. Thirdly, reducing noise will not only hurt people's hearing, but also cause muscle tension, rapid heartbeat, vasoconstriction and digestive system discomfort-this is the same as the reaction of people when they are scared or stressed. If people are exposed to noise for a long time, it will lead to adverse changes in blood pressure, cholesterol level and immune function. A study by Cornell University in the United States found that women who work in noisy environments release more adrenaline than women who work in quiet offices and are more likely to suffer from heart disease. The sound that makes people feel uncontrollable, such as car flute and dog barking, is more harmful to human body. Therefore, people should try to control the sound around them, even if they are wearing headphones, or ask restaurant owners and gym managers to turn down the volume of the stereo. Fourth, keep a positive attitude. The immune system will be hinted by thoughts and feelings, so keep a positive attitude. Researchers at the Mayo Clinic in the United States found that optimists live longer than pessimists when they are young 12 years. Recently, Anna L. Masland, a psychologist at the University of Pittsburgh Medical Center, also found in her research that people who are negative, depressed and easily stressed have much weaker resistance to hepatitis virus than their optimistic peers. 5. The lack of any kind of nutrition in a reasonable diet will lead to repeated attacks and long-term existence of diseases. When people feel hungry, the body will secrete adrenaline; If you lose more than 850g per week, T cells resistant to diseases and foreign viruses will be inhibited. In this regard, experts suggest eating some foods containing unsaturated fatty acids, taking enough protein, eating more fruits and vegetables, and drinking more fruit juice and boiled water. The effect of health care products that claim to improve immunity is not obvious. Vitamin supplement: Take proper 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. 6. Laughter, anger and sadness will damage health, while laughter will have the opposite effect. Laughter can make immune cells more active. To prove this, Burke showed the students a funny video and measured their immune system response. It turns out that even hearing a humorous joke can improve immunity. In addition, laughter can promote circulation and digestion, lower blood pressure and relieve muscle tension. 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 they are prone to catching a cold or suffering from other diseases. Seven, more active brain thinking activities can improve immunity. Marianderu Mond, a neuroscientist at the University of California, found that playing bridge can stimulate the activity of immune cells. Her research reveals for the first time the close relationship between the parts of the brain responsible for planning, memory, judgment and abstract thinking and the immune system. Diamond said: "Any thinking activity, as long as it is applied to the intellectual function of the brain, will be good for immunity." Eight, more activities, regular long-term moderate exercise can enhance the body's resistance. Burke said: "Physical exercise is not only good for the cardiovascular system, but also good for improving mood and reducing stress." However, the intensity of activities should be appropriate. If you feel tired and exceed your usual tolerance, you should adjust it in time. Three studies conducted by sports experts point out that the number of immune cells will increase and the resistance will increase relatively if you exercise for 30 to 45 minutes a day, 5 days a week for 12 weeks. Exercise as long as your heart beats faster. Walking after meals is very suitable. Learning to relax stress will make the human body secrete steroid hormones and adrenaline, thus slowing down the response of the immune system. This explains why people are particularly prone to catch a cold when they are under great pressure, such as facing the final exam and emotional crisis. In addition, anxiety caused by stress will also reduce people's resistance. Regular practice of relaxation techniques, such as aerobic exercise and gradual relaxation of whole body muscles, can inhibit the release of stress hormones and enhance immune function. Ten, turn off the lights in the dark, the human body will produce melatonin to fight disease. Lack of sleep or long time in the light at night will reduce the release of melatonin and increase the secretion of estrogen, which is easy to get breast cancer. Recent studies show that the proportion of women who work at night is as high as 60%, and the proportion of women who like to make the bedroom bright is even higher. The proportion of blind women suffering from breast cancer is 20%-50% lower than that of normal people. Even weak light sources such as bedside alarm clock and nightlight can inhibit the release of melatonin. Therefore, the darker the bedroom, the better. Sleep through sleep is closely related to human immunity. 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. Xi。 Restrict 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. Twelve. The research and application of microecological preparations to improve the internal ecological environment and improve immunity have a long history. Studies have shown that the beneficial flora represented by intestinal Bifidobacterium and Lactobacillus have 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. And produce a variety of antibodies to 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.
