Women, coffee consumption, and colon cancer risk: An analysis of 96,162 subjects (46,023 men and 50,139 women) found that the higher the amount of coffee consumption, the lower the risk of developing colon cancer. Specifically, women drinking 3 or more cups of coffee a day were found to have half the risk of developing colon cancer (but not rectal cancer) compared with those who drank no coffee at all. No benefit in terms of colon cancer risk reduction, however, was found in men. (18)
Resveratrol and colon cancer:
The relationship between resveratrol, a chemopreventive compound (found in the skin of red grapes, red wine, berries, peanuts, and other food products) and colon cancer was analyzed by Juan, ME et al. Studies conducted in vitro (in an artificial environment such as a petri dish) showed that protective activity takes place by prevention of proliferation and the initiation of cell death (apoptosis). In animal models of colon carcinogenesis, the process by which normal cells are transformed into cancer cells, resveratrol not only reduced the number of lesions before the formation of a tumor but also reduced the risk of developing new tumors and the multiplicity of tumors. Current findings suggest that oral administration of resveratrol may contribute to the prevention of colon cancer. (19)
