Three dietary methods to stay away from cancer

　　Sun Simiao, a famous doctor in the Tang Dynasty, said in his "Qianjin Prescription": "If you want to treat the disease, you should first treat it with diet. If the diet fails, then use medicine." ” cancer In research on the causes, some estimate that diet accounts for about 35% and smoking accounts for 30%. If the diet is arranged properly, the risk of cancer can be reduced by 55%. 50 years ago, the United States stomach cancer The mortality rate is very high. Japan has the highest incidence rate of gastric cancer in the world. Now it has dropped significantly. Dietary control is an important factor. In Shanghai, meat and egg intake has increased significantly in the past 30 years, the proportion of fat in total calories has increased from 20.1% to 28%, and the cause of death from cancer has increased from 7th to 1st. Therefore, to prevent cancer, we must follow three principles in diet.

　　First, don’t be too salty

　　If you reduce salt and salted products and eat more fresh vegetables and fruits, the incidence of gastric cancer will decrease. Nitrite is the number one killer of tumors. Stale vegetables, cured ham, Pickle All contain this carcinogen. Under normal conditions, dietary nitrite does not harm the human body healthy Only excessive intake of nitrite and lack of vitamin C in the body will cause harm to the human body. If you eat too salty food, it will damage the gastric mucosa and promote the reduction of nitrates into nitrites.

　　Second, don’t be too detailed

　　The grains modern people eat are too refined, which greatly reduces their fiber intake. Cellulose can absorb a large amount of water, promote intestinal peristalsis, speed up the excretion of feces, shorten the residence time of carcinogens in the intestines, and reduce adverse stimulation to the intestines, thereby preventing the occurrence of intestinal cancer. Whole grains, oatmeal, celery, fungus, etc. are all foods rich in fiber. However, excessive intake of fiber will affect the absorption of many nutrients and reduce physical strength, so 10-30 grams per day is appropriate.

　　Third, don’t overdo it

　　Surveys show that if the intake of oil and animal protein increases, colorectal cancer, breast cancer , prostate cancer, and pancreatic cancer incidence rates will increase. Frying food at high temperatures will produce benzopyrene, heterocyclic amines and acrylamide, which may be related to lung adenocarcinoma in women, while boiling and steaming in microwave ovens will not.

　　The World Health Organization has also put forward five suggestions for preventing cancer through reasonable living and eating habits.：

　　1. Limit animal fats；

　　2. Increase crude fiber；

　　3. Reduce meat consumption；

　　4. Increase fresh fruits and vegetables；

　　5. Avoid obesity.

　　Here we would also like to recommend some anti-cancer foods to you:

　　1. Cruciferous plants : Including cabbage, Chinese cabbage, white radish, cauliflower, and rapeseed.

　　2. Liliaceae plants : There are onions, garlic, lily, etc., but when cooking, they should not be overheated and fried.

　　3. Fruit : Citrus, kiwi, apple, pineapple.

　　4. Fungi : Shiitake mushrooms, straw mushrooms, mushrooms, and fungus. Be careful not to rinse them repeatedly.

　　5. Miscellaneous grains : Corn, millet, sweet potato, oats, barley, be careful not to wash too much.

　　In addition, eat fish, shellfish and meat in moderation, but do not smoke or grill them when cooking.

　　Tips to prevent cancer

　　Exercise 40 minutes a day . 40 minutes of high-intensity aerobic exercise (running, swimming, skiing, cycling, etc.) can help lower insulin levels and inhibit tumor growth. In addition, aerobic exercise can also promote digestion, accelerate intestinal emptying, and reduce the retention time of carcinogens. Maximum during exercise heart rate 65%~85% has the best effect.

　　Spend 10 minutes in the sun every day . Experts have found that vitamin D helps change intestinal cell growth and prevent cancer. Spending 10 minutes in the sun every day without sunscreen will help your body produce enough vitamin D. In winter, when there are fewer opportunities to bask in the sun, it is best to supplement vitamin D every day.

　　Eat sea fish and drink white tea often . Experts say that to prevent colon cancer, there should be fish rich in omega-3 fatty acids in the refrigerator, such as hairtail, yellow croaker and other marine fish. The latest research has found that white tea has a stronger inhibitory effect on tumor cells than green tea.

　　99 warm reminder from enthusiastic doctors Cancer should be prevented and treated early. Eat more foods that enhance immunity, such as allicin. Regular consumption has obvious detoxification and anti-cancer effects.
