Episode notes
Fiber Labels Can Be Misleading
- Many popular 'high-fiber' foods can harm the gut because they contain insoluble fiber or are highly processed.
- Dr. Stephen Gundry argues soluble fibers that reach the colon feed beneficial bacteria and produce healthful postbiotics.
Choose Soluble Prebiotic Fibers
- Favor soluble, fermentable fibers like inulin, ground flaxseed, psyllium, resistant starches, jicama, and avocados.
- Use ground flax kept refrigerated and buy 100% psyllium without sweeteners to avoid gut damage.
Gut Bacteria Make Systemic 'Postbiotics'
- Feeding gut bacteria the right fibers produces short-chain fatty acids like butyrate that nourish colon cells and mitochondria.
- Butyrate supports immunity, brain cells, and reduces inflammation systemically.
