Fermentation of dietary fibers by gut bacteria produces short-chain fatty acids (SCFAs) like butyrate, acetate, and propionate, which reduce inflammation, provide energy to colon cells, and regulate metabolism.
Eat fiber-rich foods to feed your gut bacteria, which will produce beneficial short-chain fatty acids that reduce gut inflammation and support colon health.

The metabolites of carbohydrate breakdown are SCFA, primarily acetate, propionate and butyrate, and the synthesis of these products has been shown to have benefits including: (i) reduced inflammation in IBD; (ii) an energy source for colonic mucosa cells; and (iii) differentiation and apoptosis of host colonic cancer cells.
Why this rating
Well-established biochemical mechanisms and consistent findings across multiple studies.

- Consuming complex, whole plant foods containing diverse dietary fibers and phytonutrients increases gastrointestinal tract (GIT) microbiota diversity and stability more effectively than consuming purified fiber isolates or ultra-processed foods.Good
- Low dietary fiber intake leads to a reduction in gut microbiota diversity and promotes the degradation of host mucus, increasing susceptibility to inflammation and colitis.Good
