Moreover, the gut microbiome influences the production of short-chain fatty acids (SCFAs) during the fermentation of dietary fibers. SCFAs, like butyrate, have anti-inflammatory properties and are thought to cross the blood-brain barrier, thereby modulating brain function. Conditions marked by inflammation in the brain have been linked to mood disorders. Therefore, maintaining a diverse gut microbiome through a fiber-rich diet can lead to increased SCFA production, promoting both gut and brain health, subsequently improving emotional stability.
