The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.

“But um you know purified fibers are definitely very different um both in terms of the diversity of structures but also in terms of how rapidly they're fermented in the gut because um you know if you are eating plants the complex structures there really slow the microbes down in terms of fermentation and you end up with a slow rate of fermentation over the length of your colon as opposed to this big burst of fermentation that can happen if you eat something that is highly soluble and and easily accessed by the microbes.”
