Study finds a link between eating purple potatoes and a lower risk of colon cancer
To reach their findings, the researchers fed three groups of pigs one of three diets for 13 weeks: A standard control diet, a high-calorie diet or a high-calorie diet supplemented with raw or baked purple potatoes.
After the 13-week period, they screened the pigs’ colonic tissue for markers associated with colon cancer
. They discovered that the animals who ate a high-calorie diet had higher levels of IL-6, a pro-inflammatory protein tied to a higher colon cancer risk, than those in the control group.
