1, eat less sugar cancer cells’ favorite “food” is sugar. The Japanese book “How to prevent and treat cancer” points out that when blood flows through a tumor, about 57% of the blood sugar will be consumed by cancer cells and become the nutrients that nourish it. The American Journal of Clinical Nutrition states that the risk of pancreatic cancer is 90% higher with just two sweet drinks a day than with no drinks. Hao Jihui, director of the Department of Pancreatic Oncology at the Cancer Hospital of Tianjin Medical University and a member of the American Cancer Fund Research Institute, said 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. 2. Open the window for at least half an hour Few people know that besides formaldehyde, there is also a very strong carcinogenic gas – radon and its daughter. It is usually hidden in granite, cement and tiles, and spreads indoors along the cracks of these places and enters human body through respiratory tract, which will induce lung cancer after a long time. In fact, 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, radon will also be produced after natural gas burning, so when boiling water in the kitchen, it is better to open the window and close the door connected with the living room. 3.Eat with onion and garlic In China, the province with the lowest incidence of stomach cancer is Shandong, a major province of onion and garlic cultivation. Among the four counties with the lowest mortality rate of stomach cancer north of the Yangtze River, the first one is Cang Shan County, Shandong Province , where each person eats 6 kg of garlic every year. Experts point out that this is related to the antioxidant effect of allicin, which can reduce the level of carcinogens nitrite in the body. Some 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 can quickly lose its effect 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. 4, four cups of green tea a day The Japanese who love tea have spent nine years doing a survey and found that drinking as little as 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 the Chinese Center for Disease Control and Prevention, has conducted 17 years of research on the cancer prevention effects of tea, and 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 significant effect, and its cancer prevention ingredients are five times more than other teas. However, it is best not to drink tea that is too strong and too hot, otherwise it will affect its anti-cancer effect. The best temperature for drinking tea should be about 60 degrees Celsius, and the tea should be steeped for 5 minutes before the active ingredients can be dissolved in the water. 5.Wipe your back with a dry towel Japan had set off a wave of dry towel back rubbing craze. Professor Mizuno, vice president of the University of Tokyo, 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, can play a role in engulfing and destroying cancer cells. For the elderly, rubbing, rubbing or scratching the back is a good way to take care of yourself. Or use a dry towel ends, straight, horizontal repeatedly rub the entire back for about 10 minutes, until the skin is red and hot. 6, a bite of rice chewed 30 times Investigations have shown that people who always eat in one gulp have a higher chance of developing stomach 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 found that saliva has a strong “anti-toxic” effect and can make the toxicity of aflatoxin, the main culprit of liver cancer, disappear almost completely within 30 seconds. Therefore, according to a second chewing to calculate, a bite of rice is best chewed 30 times, in order to have a cancer prevention effect. 7, walking for an hour a day The American magazine Reader’s Digest has told us 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 School of Public Health long-term study of 70,000 people also found that just one hour of walking a day can reduce the chances of colorectal cancer by half. This is because pancreatic cancer is related to excessive body heat, and walking can burn calories, which can directly prevent pancreatic cancer, explained Sun Preservation, a member of the National Committee of the Chinese People’s Political Consultative Conference and deputy director of the Institute of Oncology at Tianjin Medical University. In addition, sweating after exercise can make carcinogenic substances such as lead and strontium excreted from the body with sweat, thus playing a role in cancer prevention. 8. 15 minutes of sunshine Among the cheapest cancer prevention prescriptions, sunshine is the ultimate, which can prevent cancer by increasing the content of vitamin D in the body without any cost. Vitamin D deficiency can increase the risk of breast, colon, prostate, ovarian and stomach cancer. To avoid increased risk of skin cancer from sun exposure, just 15 minutes of sunlight a day is enough. The grape skins used to make red wine contain a substance called resveratrol, which has a preventive effect on digestive tract cancers. In addition, the American Association for Cancer Research recommended consumption of pork, beef, lamb and other red meat is about 500 grams per week, eating too much, it 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 breaking down into harmful substances in the stomach. The American Association for Cancer Research 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 slows down the production of estrogen in women’s bodies, thus inhibiting the purpose of breast cancer. Shi Ming, deputy director of the Shanghai TCM Insomnia Medical Collaborative Center, suggests that it is best to start washing up before 10:30 p.m., get ready for bed, make sure you fall asleep before 11 p.m. and get up at 6-7 a.m. In addition, German sleep experts point out that 1:00 pm is an obvious peak of sleep during the day, when a nap can also enhance the activity of immune cells in the body and play a certain role in cancer prevention. May you always be healthy!
