Potato Fiber and Gastrointestinal Function: Phase 3

NCT01964599 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 90

No results posted yet for this study

Summary

The primary physiological impacts of fiber intake include the gastrointestinal effects of stool bulking, increased stool frequency and decreased gastrointestinal transit time (GTT). Fermentation of resistant starches by microbiota increases bacterial numbers, which increases fecal bulk and may impact frequency and transit time. The purpose of this study is to determine the effects of resistant potato starches (potato fiber) on stool frequency, transit time and microbiota in healthy individuals.
