1, fat intake should be reduced: high-fat diet, namely saturated fat and unsaturated fat, should be avoided after colon cancer surgery. A large number of studies have confirmed that the fat in the diet will promote the growth of cancer cells. Whether it is animal fat or plant fat, try to reduce the intake. Excessive fat, especially animal fat, will stimulate the small intestine to secrete bile acids. When the content of cholic acid in intestine is too high, it is easy to become carcinogen and promote the growth of cancer cells. But we can't eat animal oil, mainly vegetable oil, which will cause too much peroxide in the body. It is suggested that patients with colon cancer should pay attention to reasonable intake of oil after operation to avoid overeating.

2, colon cancer postoperative diet should increase the intake of cellulose, colon cancer postoperative diet patients should pay attention to eat more vegetables or fruits rich in dietary fiber, stimulate intestinal peristalsis, increase the number of defecation, reduce the time of carcinogens and bacteria in the intestine, but after colon cancer surgery should pay attention to excessive intake of cellulose will cause intestinal obstruction, should be given digestible, soft semi-liquid food, can reduce the stimulation to the intestine, more smoothly through the intestinal cavity, to prevent the occurrence of intestinal obstruction. Therefore, after colon cancer surgery, various nutritional elements should be properly supplemented according to the patient's own physique, but attention should be paid to the right amount.

3.
