Research studies suggest that a high-fiber diet protects against colon cancer. This is because high fibrous food increases the bulk in the digestive tract to pass easily through the intestinal tract to shorten the time of passage. This short time of passage of food reduces the interaction of carcinogens present in the food with the intestinal tract. The fibers are broken down in butyrate by the bacteria present in the lower intestine. This butyrate inhibits the growth of tumors of colon and rectum,
