1, with a dry towel back Japan has set off a wave of dry towel back rubbing craze. Japanese experts pointed out that this can play a role in cancer prevention, because the friction of heat will activate a cell in the subcutaneous muscle tissue of the back, which can play the role of engulfing and destroying cancer cells. For the elderly, whether it is rubbing, rubbing or scratching the back, is a good health care method. Or use both ends of a dry towel, straight and horizontal to repeatedly rub the entire back for about 10 minutes until the skin is red and hot. 2.Eating with onion and garlic It is known that Cang Shan County in Shandong is one of the few counties with the lowest mortality rate of stomach cancer north of the Yangtze River, where each person eats 6 kg of garlic per year. This is related to the fact that allicin has antioxidant effects and can reduce the level of carcinogens nitrite in the human body. Studies have shown that people who eat more garlic have a 60 percent lower risk of stomach cancer. Allicin is only produced when garlic is crushed and fully combined with oxygen, and it is very unstable and loses its effect quickly when exposed to heat. Therefore, it is best to crush garlic and eat it raw, or chop it into garlic paste and put it in cold dishes. 3. Drink a glass of red wine when eating meat The American Association for Cancer Research’s recommended consumption of red meat such as pork, beef and lamb is about 500 grams per week, and eating too much can increase the risk of colon cancer. However, a recent study found that if you drink a glass of red wine while eating meat, the polyphenols in it can prevent the meat from breaking down into harmful substances in the stomach. The grape skin used to make red wine contains a substance called resveratrol, which has a preventive effect on digestive tract cancer. 4, 1 p.m. is the most cancer prevention The survey found that women who sleep less than 7 hours a night have a 47% chance of developing breast cancer. This is because sleep produces a melatonin, which can slow down the production of estrogen in women’s bodies, thus serving the purpose of inhibiting breast cancer. Academician Tang suggests that it is best to start washing up before 10:30 pm, get ready for bed, go to sleep before 11 pm and get up at 6-7 am. In addition, German sleep experts point out that 1 pm is an obvious peak of sleep during the day, and a nap at this time can also enhance the activity of immune cells in the body and play a certain role in cancer prevention. 5.Chew 30 times a mouthful of rice. Investigation proves that people who always swallow their meals in one gulp have a higher chance of stomach cancer. Chewing more can reduce the burden of food on the digestive tract and lower the risk of gastrointestinal cancer. In addition, the University of Georgia experiment found that saliva has a strong “anti-toxic” effect, which can make the toxicity of aflatoxin, the main culprit of liver cancer, significantly reduced within 30 seconds. Therefore, according to the calculation of chewing once a second, it is better to chew 30 times a mouthful of rice in order to have cancer prevention effect. 6.Eat less sugar The favorite “food” of cancer cells is sugar. In the Japanese book “How to prevent and treat cancer”, it is pointed out that when blood flows through tumors, about 57% of the blood sugar will be consumed by cancer cells and become nutrients to nourish them. The American Journal of Clinical Nutrition states that the risk of pancreatic cancer is higher with as few as two sweet drinks a day than with those who do not drink them. Therefore, it is best to eat less or no sugary foods. Internationally, it is generally believed that the daily intake of sugar per person should be within 50 grams. 7. Open the window for at least half an hour Besides formaldehyde, decoration pollution also has a very strong carcinogenic gas – radon and its daughter. It is usually hidden in granite, cement and tiles, and spreads indoors along the cracks in these places and enters human body through the whistling channel, which will induce lung cancer after a long time. If you open the window for half an hour every day, the concentration of radon can be reduced to the same level as outdoor. In addition, natural gas burning will also produce radon, so when boiling water in the kitchen, it is better to open the window and close the door connected with the living room. 8, walk for one hour every day The American Reader’s Digest magazine reported that a 30-minute walk after meals or a four-hour walk every week can reduce the risk of pancreatic cancer by half. Harvard University’s long-term study of 70,000 people also found that walking for an hour a day can reduce the chances of colorectal cancer by half. In addition, sweating after exercise can make the body of lead, strontium and other substances with sweat out of the body, which may help prevent cancer. 9.Drink 6 glasses of water a day The New England Journal of Medicine, one of the most authoritative medical journals in the world, shows that men who drink 6 glasses of water a day (240 ml each) will reduce the risk of bladder cancer by half, and women will reduce the risk of colon cancer by 45%. 10, soya milk to prevent “female cancer” American Association for Cancer Research pointed out that women who often drink soya milk have a much lower risk of breast cancer. This is because soy milk has “soy isoflavones”. It has a preventive effect on all estrogen-related cancers, such as breast cancer, endometrial cancer, cervical cancer and prostate cancer. 11, 15 minutes of sunshine Sunshine can prevent cancer by increasing the amount of vitamin D in the body. Vitamin D deficiency can increase the risk of breast, colon, prostate, ovarian and stomach cancer. To avoid increasing the risk of skin cancer by exposure to the sun, just 15 minutes of sunlight a day is enough. 12.4 cups of green tea per day It has been reported that some experts have conducted 17 years of research on the cancer prevention effects of tea and found that oolong tea, green tea and black tea have good preventive effects on oral cancer, lung cancer, esophageal cancer and liver cancer. Among them, green tea, including Longjing, Biluochun and Mao Feng, has the most significant effect, and its cancer prevention-related ingredients are five times higher than those of other teas. However, it is best not to drink tea that is too strong and too hot. The best tea drinking temperature should be about 60 degrees Celsius, and the tea should be steeped for 5 minutes before the active ingredients are dissolved in the water.
