Episode notes
Butyrate Fuels Colon Energy
- Colonocytes get roughly 70%–80% of their energy from butyrate produced by microbial fermentation of fiber.
- This fuels ATP production via acetyl-CoA and the Krebs cycle to maintain gut lining functions.
Butyrate Supports Gut Barrier
- Butyrate supports normal expression of tight-junction proteins like ZO-1 and occludin to maintain barrier integrity.
- Metabolizing butyrate lowers local oxygen, favoring anaerobes that produce more SCFAs and mucus.
Add Diverse Whole-Food Fiber Slowly
- Eat varied fiber from whole fruits, vegetables, legumes, and whole grains to provide substrates for butyrate-producing microbes.
- Increase fiber gradually to avoid bloating and allow your gut microbiome to adapt.
