First seen Jan 12, 2026 · Last updated Apr 30, 2026 · Updated 14 times
Summary
This study looked at how two types of dietary fiber—psyllium and inulin—affect gut bacteria and related substances in healthy adults over 60. Participants took each fiber (or a placebo) for two weeks, with breaks in between. The goal was to see if some people respond better to fiber than others, which could help personalize diet advice for gut health.
