Fiber Feeds the Microbiome
How does fiber impact the gut microbiome?
Fiber acts as fuel for gut microbes, producing short-chain fatty acids that lower inflammation and improve longevity.
Explanation
Fiber that resists digestion reaches the colon, where it is fermented by gut microbes into short-chain fatty acids (SCFAs) such as butyrate. SCFAs strengthen the gut barrier, regulate immune signaling, and lower systemic inflammation.
Practical Emphasis
Aim for multiple fiber sources daily — beans, oats, vegetables, and seeds — to ensure a robust and diverse microbiome.
Action Tip
Increase fiber variety (soluble + insoluble) to feed gut microbes and promote SCFA production.
