Increasing microbial production of short-chain fatty acids (SCFAs) via dietary fiber or prebiotic intake improves gut barrier integrity and reduces intestinal inflammation.
To support gut health, focus on consuming diverse sources of indigestible carbohydrates (prebiotics and soluble fibers) to feed your gut bacteria. This encourages the production of SCFAs like butyrate, which fuel colon cells and strengthen the gut barrier. Do not rely on faecal SCFA tests to gauge success, as they are unreliable indicators of total production.
These include health effects that are attributed to increased microbial SCFA formation including an improved gut barrier function and reduced intestinal inflammation.
Why this rating
The paper states that while mechanistic data is strong, well-controlled human studies are limited and mostly based on animal models.
