Episode notes
Fiber Isn’t One Thing
- Fiber is not a single nutrient; soluble, insoluble and viscous fibers have different effects on health and digestion.
- Viscous soluble fibers (e.g., psyllium, pectin) specifically lower cholesterol and slow glucose absorption by trapping bile and glucose.
Choose Viscous Fiber For Cholesterol And Glucose
- Prefer viscous soluble fibers like psyllium or pectin when your goal is to lower cholesterol or blunt post-meal glucose spikes.
- Check product labels because some commercial fiber mixes add sugar or artificial additives that negate benefits.
Evidence Mostly Reflects Standard Diets
- Most fiber research is done in people eating a standard American diet, not in people on restrictive diets like carnivore or strict vegan.
- That leaves a knowledge gap for low-carb, keto, and carnivore communities about fiber's effects in those contexts.
