The American Association for Cancer Research points out that women who regularly drink soy milk have a much lower risk of breast cancer. Wang Xingguo, Deputy Secretary-General of Dalian Nutrition Society and Director of Nutrition Department of Dalian Central Hospital: This is because there is a substance in soybean milk that is very similar to estrogen, called "soybean isoflavone", which can play the role of confusing the fake with the real, and the mechanism of action is very similar to that of anticancer drugs. It can prevent all estrogen-related cancers, such as breast cancer, endometrial cancer, cervical cancer and prostate cancer.

However, Wang Xingguo warned that people who already have these cancers had better not drink soy milk, so as not to stimulate cancer cells. In addition, people suffering from peptic ulcer, gastritis and gout should also drink less. It is best to drink your own ground soybean milk. Many products sold on the street are made of soybean milk powder, and the content of soybean isoflavones is very low.

2. 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.

3. Drink 6 glasses of water every day.

A study in 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 grams per cup) have a reduced risk of bladder cancer by half, and women have a reduced risk of colon cancer by 45%. Peng Yifan, deputy director of colorectal surgery at Beijing Cancer Hospital, said that this is because drinking water can increase the number of urination and defecation, and discharge harmful substances that may irritate bladder mucosa and colon, such as urea and uric acid. He also reminded that it is best for people over 40 to have a colonoscopy every two or three years. If there are polyps, early detection can reduce the chance of cancer.

4. Eat with onions and garlic.

In China, the province with the lowest incidence of gastric cancer is Shandong, a big onion and garlic planting province. Cangshan County, Shandong Province is the first of the four counties with the lowest mortality rate of gastric cancer in the north of the Yangtze River, with an average of 6 kilograms of garlic per person per year.

Wang Xingguo pointed out that this is related to the antioxidant effect of allicin, which can 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.

Sunbathing for 5 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, and there is no cost. Professor Hong Zhaoguang, the chief health education expert of the Ministry of Health, told the reporter of Life Times that 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.

6. Four cups of green tea a day

Japanese who love tea once spent nine years doing a survey 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. 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.

7. Open the window for at least half an hour.

Few people know that in addition to formaldehyde, 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
