Higher total dietary fiber intake (specifically from cereals) is inversely associated with colorectal cancer risk, with a 13% risk reduction per 10 g/day increase in total fiber.

To potentially lower your risk of colorectal cancer, aim to increase your daily dietary fiber intake by 10 grams. This can be achieved by adding whole grains, fruits, and vegetables to your diet. The study suggests that cereal fiber, in particular, is strongly associated with reduced risk for both colon and rectal cancers.

GoodSupportsHIGH confidence
In calibrated models, a 13% lower (95% CI: 0.79–0.96) colorectal cancer risk per 10 g/day increase in total fibre intake was yielded.
