A diet enhanced with multivitamin and mineral supplements may dramatically lower the risk of developing precancerous colon cancer lesions, according to research published in the Canadian Journal of Physiology and Pharmacology. Nearly 150,000 men and women
in the United States are diagnosed with this second-most common form of cancer each year.
In the study, rats were fed a highfat (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.
