Here's the summary Brave gives for "fiber and colon cancer", you can follow the link below and examine the sources at your leisure (I'm not copy-pasting everything for you.)
Fiber and Colon Cancer
Dietary fiber is strongly associated with a reduced risk of colorectal cancer through multiple mechanisms. A high-fiber diet, particularly from whole grains, fruits, vegetables, and legumes, promotes gut health by increasing stool bulk and shortening transit time, which reduces the colon's exposure to potential carcinogens.
Fiber fermentation by gut bacteria produces short-chain fatty acids (SCFAs), especially butyrate, which serves as the primary energy source for colon cells and has anti-inflammatory and anti-cancer properties, including promoting apoptosis (programmed cell death) in abnormal cells.
Research consistently shows that each 10 grams of daily fiber intake is linked to a 10% reduction in colorectal cancer risk, with whole grains showing particularly strong protective effects. Some studies suggest a minimum of 50 grams of fiber per day may be optimal for colon health, though most experts recommend aiming for 25–30 grams daily from whole food sources.
Key benefits include:
Feeding a healthy gut microbiome
Lowering inflammation and oxidative stress
Improving metabolic health and reducing obesity risk (a known cancer risk factor)
Important notes:
Increase fiber intake gradually and stay well-hydrated to avoid bloating or discomfort.
Focus on whole foods rather than supplements for maximum benefit.
While “fibermaxxing” (extreme fiber intake) is trending, it’s not necessary and may cause digestive issues; moderation and consistency are key.
For personalized guidance, consult a registered dietitian or healthcare provider.
Unfortunately no-fiber keto faction tends to also believe a lot of outdated concepts like not understanding that gluconeogenesis is demand driven. The whole "no more than 20 grams" thing is just to dumb it down as really everyone's threshold is different (I've still had detectable ketones at as high as 70g of carbs.)
