Fiber showdown: which type slows digestion the most?
NCT ID NCT03982836
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested how two types of soluble fiber—fructooligosaccharide and partially hydrolyzed guar gum—affect how fast food leaves the stomach and moves through the intestines. Twenty-five healthy adults each tried both fibers and a placebo on separate days. The goal was to see if these fibers slow digestion differently, which could help guide their use in managing appetite or gut health.
