Why gut and colon health matter
Why it matters
Colorectal cancer is one of the most preventable cancers: removing precancerous polyps at colonoscopy cut colorectal cancer deaths by about half in a cohort followed for up to 23 years [1]. Diet matters here too: people eating 25 to 29 g of fiber a day had about 16% lower colorectal cancer risk [2]. Rates are rising in adults under 50 [3].
