Can a South African Diet Reduce Colon Cancer Risk Among Americans?
Based on the dramatic effects observed when American and South African volunteers swapped diets for just two weeks, researchers suggest that a diet high in fiber and low in fat could possibly reduce an individual’s risk for developing colon cancer. After fourteen days on the high-fiber, low-fat South African diet, the American group had significantly less inflammation in the colon along with a reduction in biomarkers associated with colon cancer risk. Meanwhile, tests on the African group showed the opposite, indicating a dramatic increase in cancer risk after just two weeks on the high-protein, low-fiber American diet. According to the study’s authors, one could achieve similar results by increasing their fiber intake to 50 grams per day.
