Dietary fiber, whole grains, and risk of colorectal cancer: systematic review and dose-response meta-analysis of prospective studies.

Generous intake of whole grains and fiber-rich foods, such as fruits, vegetables, legumes, and cereals, may help guard against the development of colorectal cancer.

This study was carried out to determine the role of high dietary ingestion of whole grains and fiber-rich foods in the prevention of colorectal cancer. Researchers collated and analyzed dietary and clinical data extracted from 25 prospective cohort studies. They found out that habitual consumers of whole grains and fiber-rich foods, such as fruits, vegetables, cereals, and legumes, had slim chances of developing colorectal cancer. The findings of this meta-analysis suggest that consistent consumption of diets high in whole grains and fiber may decrease the rates of colorectal cancer in the general population.
