2. Open the window for at least half an hour every day. Few people know that besides formaldehyde in decoration pollution, there is also a strong carcinogenic gas-radon and its daughters. It is usually hidden in granite, cement and ceramic tiles. It spreads indoors along the gaps in these places and enters the human body through the respiratory tract. After a long time, it will induce lung cancer. In fact, as long as the window is opened for half an hour every day, the concentration of radon can be reduced to the same as that outside. In addition, natural gas will also produce radon after burning, so when boiling water in the kitchen, it is best to open the window and close the door connected to the living room.
3. Onion and garlic are eaten together. In China, the province with the lowest incidence of gastric cancer is Shandong, a big onion and garlic planting province. Among the four counties with the lowest mortality rate of gastric cancer in the north of the Yangtze River, Cangshan County in Shandong Province ranks first, with a per capita consumption of 6 kilograms of garlic every year. Experts pointed out that this is related to the antioxidant effect of allicin and its ability to reduce the content of carcinogen nitrite in human body. Studies have shown that people who eat more garlic will reduce the risk of gastric cancer by 60%. Garlic can only be produced when it is crushed and fully combined with oxygen, and it is very unstable and will soon lose its effect once heated. So it's best to crush garlic and eat it raw, or chop it into garlic paste and put it in the cold salad.
4. Four cups of green tea a day The Cancer Research Institute spent nine years investigating people who love tea, and found that drinking four or five cups of tea a day can reduce the risk of cancer by 40%. Professor Han Chi, a researcher at the Institute of Nutrition and Food Safety of China Center for Disease Control and Prevention, has studied the anticancer effect of tea for 17 years. He 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 remarkable effect, and its anticancer components are five times that of other teas. But it is best not to drink tea that is too thick and hot, otherwise it will affect its anti-cancer effect. The best temperature for drinking tea should be about 60 degrees Celsius. After tea leaves are soaked for 5 minutes, the effective components can be dissolved in water.
Wipe your back with a dry towel. A few years ago, there was a craze to wipe your back with dry towels. Professor Mizuno, vice president of the University of Tokyo, pointed out that this can play a role in preventing cancer, because friction and heating will activate a cell in the subcutaneous muscle tissue of the back, which can devour and destroy cancer cells. For middle-aged and elderly people, rubbing, rubbing or scratching their backs is a good health care method. Or use both ends of a dry towel to repeatedly rub the whole back in a straight or horizontal way for about 10 minutes until the skin is red and hot.
6. Chewing a mouthful of rice for 30 times proves that people who always swallow dates are more likely to suffer from gastric cancer. Chewing more can reduce the burden of food on the digestive tract and reduce the risk of gastrointestinal cancer. In addition, experiments at the University of Georgia in the United States found that saliva has a strong "toxic" effect, which can make the toxicity of aflatoxin, the chief culprit of liver cancer, disappear almost completely within 30 seconds. Therefore, according to the calculation of chewing once a second, it is best to chew a meal for 30 times to prevent cancer.
7. Walk every day 1 hour. The American magazine Reader's Digest once told everyone that walking for 30 minutes after meals every day or walking for 4 hours every week can reduce the risk of pancreatic cancer by half. A long-term study of 70,000 people by Harvard School of Public Health also found that walking 1 hour every day can reduce the risk of colorectal cancer by half. Sun Cun, member of the Chinese People's Political Consultative Conference and deputy director of the Institute of Cancer Research of Tianjin Medical University, explained that this is because pancreatic cancer is related to excessive body heat. Walking can consume calories and can directly prevent pancreatic cancer. In addition, sweating after exercise can cause carcinogens such as lead and strontium in the body to be excreted with sweat, thus playing a role in preventing cancer.
8. Sunbathing 15 minutes Among the cheapest anti-cancer prescriptions, sunbathing is the ultimate. It can prevent cancer by increasing the content of vitamin D in the human body without any cost. Insufficient vitamin D will increase the risk of breast cancer, colon cancer, prostate cancer, ovarian cancer and gastric cancer. In order to avoid increasing the risk of skin cancer, it is enough to get 15 minutes of sunshine every day.
9. Drinking a glass of red wine while eating meat contains a substance called resveratrol, which has a certain preventive effect on digestive tract cancer. In addition, the intake of red meat such as pork, beef and mutton recommended by the American Association for Cancer Research is about 500 grams per week. Eating too much will 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 decomposing into harmful substances in your stomach.
10. A survey by the American Cancer Society found that women who sleep less than 7 hours a night have a risk of breast cancer of 47%. This is because melatonin is produced during sleep, which can slow down the production of estrogen in women, thus achieving the purpose of inhibiting breast cancer.
