Purple Potatoes May Reduce Risk of Colon Cancer


Purple potatoes may help ward off colon cancer and inflammatory bowel diseases, according to recent research at Pennsylvania State University. Experiments were conducted on pigs, which have a digestive system similar to humans, according to the researchers. Compared to the control group, pigs fed a high-calorie diet had higher levels of colonic mucosal interleukin-6 (IL-6), a protein linked to the growth of cancer cells. However, pigs fed the high-calorie diet supplemented with purple potatoes had IL-6 levels six times lower the control group.

Understanding how these compounds work on a molecular level could be an initial step toward finding treatments for people with cancer, the researchers said. Colon cancer is the second-leading cause of cancer-related deaths in the U.S.
