After rectal cancer patients undergo surgery, they should try to eat less food containing fats and oils. In the study of the relationship between diet and cancer, one of the most studied is fats and oils, including saturated and unsaturated fats. Fats and oils in the diet can promote the growth of cancer cells and can also cause normal cells to mutate early and evolve into tumors. Both animal and vegetable fats should be reduced as much as possible. Excess fats, especially animal fats, can stimulate bile acid secretion in the small intestine. When the amount of bile acid in the intestine is too high, it can easily become carcinogenic and encourage the growth of cancer cells. Thus, high-fat diet is closely related to the occurrence of rectal cancer. Increase the intake of fiber in the diet: The main function of fiber in food is to normalize intestinal peristalsis, increase the volume of feces and reduce the time of feces staying in the rectum. The fecal matter present in the colon makes bacteria active and may produce carcinogenic substances. When there is a lack of fiber in the diet, the feces in the colon becomes dry and hard, and this, combined with a sluggish passage and weakened abdominal wall muscles, makes the evacuation time longer, and if it takes too long, the chances of developing colon cancer are relatively higher. Many studies have confirmed that fiber in food can dilute potentially carcinogenic substances in fats and oils, and can also accelerate the rate at which carcinogens are expelled from the body through the digestive system.

[ Method ] Eat 100 grams of porridge once a day for a regular meal. Radish should be cooked at low temperature Our researchers reported that vegetables such as carrots are anti-cancer because they contain an interfering inducer that can resist cell carcinogenesis and viral infection. The interferon gene, which exists in normal cells in the human body, can produce interferon once stimulated by the inducer, and interferon can effectively interfere with the survival of cancer cells and viruses. Animal experiments have also confirmed that this substance can inhibit the production of malignant tumors. Experiments have also shown that the interferon inducer contained in carrots is not heat resistant and becomes unstable above 100°C. Therefore, in order to effectively exert anti-cancer and anti-cancer effects by taking carrots, the temperature should not exceed 100°C when cooking. The anti-cancer effect of carrots is also due to its content of folic acid, biotin and carotenoids. Folic acid and biotin can prevent lung cancer. Carotene is a precursor of vitamin A. After entering the body, it is converted into vitamin A in the liver and intestinal wall, which plays an anti-cancer role.
