Studies have suggested that all of these factors contribute to the lowered incidence of colon cancer with high fiber diets. Fiber decreases contact between mucosal cells and colonic contents, decreasing the exposure of the colon to carcinogens. Fiber also decreases transit time, allowing less time for carcinogens to come into contact with colonic cells. Additionally, fiber-containing foods are usually high in phytochemicals and antioxidant vitamins, which may have protective effects against cancer.
