Data shows that about 40% of cancer patients are caused by improper diets, including colon cancer. The salient features of improper diets are excessive intake of calories, animal fat and cholesterol, and deficiency of dietary fiber and vitamin; meanwhile it is usually companied with insufficient amount of exercise.
The first category of recommendations on diet for colon cancer patients
Animal fat: studies have shown that diets of high animal fat are the high risk factor leading to colon cancer. The reason may include: (1) the more you take animal fat, the higher the risk for dissolving and absorbing more carcinogenic substances is. (2) high-fat diets would increase the secretion of bile acids in the intestinal tract, and the bile acids have potential irritation and damage to the intestinal mucosa, and long-term irritation and damage may trigger the generation of tumor cells and lead to colon cancer.
1. Eat less or don’t eat foods rich in saturated fat and cholesterol, including lard, butter, chicken fat, suet, fat meat, palm oil, coconut oil, etc.

5. During cooking process, avoid excessive heating of the animal foods or vegetable oils.
The second category of recommendation on diets for colon cancer patients
Dietary fiber: increase in the intake of dietary fiber, can reduce the incidence of colon cancer, and this is mainly because that dietary fiber has strong water absorption and can increase the volume of stool, and is conducive to defecate, what’s more, it reduces the concentration of carcinogenic substances in the intestinal canal, thereby reducing the risk of colon cancer.
1. Daily supplement more than 30 grams of dietary fiber.
2. Eat more foods that are rich in dietary fiber, such as, konjac, soy and fresh vegetables, fruits, algae, etc.

1. Eat more vegetables and fruits to supplement carotene and vitamin C.
