High dietary fiber intake does not reduce the risk of colorectal cancer or adenoma in women.
For women, increasing dietary fiber intake is unlikely to lower your risk of colorectal cancer or adenomas, despite common advice. This study suggests that other factors may be more critical for prevention.

Our data do not support the existence of an important protective effect of dietary fiber against colorectal cancer or adenoma.
Why this rating
Large prospective cohort (88,757 women), long follow-up (16 years), rigorous adjustment for confounders.
