High-fat foods such as meat, high-protein foods and low-fiber foods such as starch, potatoes, carrots, etc. have a very important relationship with the occurrence mechanism of colorectal cancer. Under the action of colon bacteria, they are converted into cholesterol metabolites and bile acid, which has a carcinogenic effect. Low-fiber foods do not absorb water, reduce the frequency of bowel movements, increase the retention of waste in the intestine, prolong the residence time of feces in the large intestine, increase the long-term contact between carcinogens and the large intestine mucosa, and thus become one of the causes of colorectal cancer. Both high fat and low fiber are carcinogens or co-carcinogens, thus increasing the occurrence of colorectal cancer.
