Supplementation Cuts Colon Cancer Risk
In the study, rats were fed a high-fat (20 percent) diet for 32 weeks. Those fed a high-fat, low-fiber diet and also exposed to a carcinogen, developed precancerous lesions of the colon. The animals that underwent a similar diet and treatment, but also received daily vitamin and mineral supplements, showed an 84 percent reduction in the formation of precancerous lesions and did not develop tumors.
