To help combat cancer, add red grapes and red wine to your nutritional arsenal. Recent research from the University of Illinois at Urbana-Champaign showed that certain components in grapes, including some newly identified ones, work together to inhibit the proliferation of cancer cells (Journal of Agricultural and Food Chemistry, 2005, vol. 53, no. 7). According to the study, compounds found in both red grapes and red wine combine synergistically against human DNA topoisomerase II, the enzyme responsible for the spread of malignant cells. Researchers say the study confirms the importance of eating whole foods, because grapes’ individual compounds don’t possess the same anticancer abilities as the components combined.
