Episode notes
Pick Diverse Fiber Not Single Ingredient Powders
- Choose fiber supplements that provide diversity: soluble and insoluble fibers plus polyphenols to feed many microbiome strains.
- Prefer blends that list multiple fiber types and added polyphenols, and check ingredient lists for low FODMAP options if sensitive.
Sneak Fiber Into Everyday Meals
- Close the fiber gap by adding a soluble, low-FODMAP fiber powder into everyday foods and baked goods.
- Colleen recommends sprinkling it into smoothies, pancakes, coffee, banana bread and kids' foods to increase intake easily.
Fiber Feeds Microbes That Trigger Natural GLP‑1
- The microbiome converts dietary fiber into signals that stimulate natural GLP‑1, which tells the brain you're full and helps process sugars.
- Missing GLP‑1–stimulating microbes can cause inappropriate hunger, sugar cravings, and disrupted metabolism.
