How does fiber lower risk of cancer?

Most of the research on fiber and cancer prevention has focused on this type of cancer, because fiber does most of its work in the colon. The nutrient passes quickly through the colon, perhaps flushing cancer-causing compounds out of the body. It may even change these compounds, making them less harmful, Daly says.

What foods reduce risk of colon cancer?

Diets that include lots of vegetables, fruits, and whole grains have been linked with a decreased risk of colon or rectal cancer.

Fiber cleans your colon, acting like a scrub brush. The scrub-brush effect of fiber helps clean out bacteria and other buildup in your intestines, and reduces your risk for colon cancer.

Does psyllium cause colon cancer?
