A new study has linked purple potatoes to a lower risk of colon cancer in pigs.

Purple potatoes may do more than add a pop of color to your plate. These vibrant tubers might also help ward off colon cancer, according to new research done on animals at Pennsylvania State University.

Purple-fleshed potatoes are particularly rich in anti-inflammatory, antioxidant compounds called phenolic acids and anthocyanins; and previous research has suggested that these compounds possess anti-cancer properties. To find out how the veggie might affect colon cancer risk, the researchers fed three groups of pigs one of three diets for 13 weeks: a high-calorie diet, a high-calorie diet supplemented with raw or baked purple potatoes, and a standard control diet.

After 13 weeks, the researchers screened the pigs’ colonic tissue for markers tied to colon cancer. They found that compared to the control group, the animals fed a high-calorie diet had higher levels of IL-6, a pro-inflammatory protein known to increase colon cancer risk. But the pigs fed the high-calorie diet supplemented with purple…
