Fiber also absorb bile acids, keeping them from acting on bacteria to produce fecapentanes, the cancerous substances that are formed by decaying foods within the colon. There are about twenty of these compounds that can mutate colon cells into cancerous cells. Fiber also promotes the growth of healthy bacteria in the intestines, which crowd out the undesirable bacteria that produce fecapentanes. Switch from red meat to seafood. Populations who eat the most red meat and fat in their diet have the highest incidence of colon cancer. Eat more soy products. Soy is a more healthful source of protein than meat. The primary anti-cancer value of soy seems to come from phytonutrients which inhibit the growth of new blood vessels necessary for tumor survival. Soy also protects against colon cancer by blocking the carcinogenic effects of bile acids. Eat a diet high antioxidants, calcium, beta-carotene and vitamin E. Calcium binds cancer-producing bile acids and keeps them from irritating the colon wall. Beta-carotene fights against cancer by both boosting the immune system and releasing a specific chemical blocking the growth of potentially cancerous cells.
