Episode description
Story at-a-glance
- Butyrate is a crucial short-chain fatty acid (SCFA) that fuels colon cells, supports gut barrier function, and promotes a balanced microbiome. Colon cells rely on butyrate for up to 80% of their energy needs, helping maintain normal gut function and a healthy intestinal lining
- Your gut bacteria produce butyrate by fermenting fiber from whole foods such as fruits, vegetables, legumes and whole grains
- Butyrate supports gut barrier integrity by regulating tight-junction proteins and contributing to mucus production, which protects the colon wall
- Diet and lifestyle significantly impact butyrate production — a high-fiber diet, exercise, hydration, sleep and avoiding processed fats all support SCFA production
- Common misconceptions about butyrate include the idea that fiber supplements alone suffice — whole foods provide a wider variety of fiber, nutrients and benefits. If gut health is compromised, gradual fiber introduction is key — eliminating gut-damaging factors first allows for better microbial balance and butyrate production
