  Purpose

Research suggests dietary fiber may decrease transit time through the gastrointestinal tract. Research studies traditionally use radio-opaque markers to determine gastric emptying, colonic transit, and whole gut transit time. The SmartPill is a single use pill that can be used to determine gastric emptying, colonic transit, and whole gut transit time without requiring X-rays or fecal collections. Previous studies have found radio-opaque markers and the SmartPill detect the similar transit times.

The purpose of this pilot study is to determine if the SmartPill can detect a change in transit time using a significant dose of dietary fiber.

Further study details as provided by University of Minnesota - Clinical and Translational Science Institute:

Primary Outcome Measures:
  • Whole Gut Transit Time [ Time Frame: 5 days ]
    The time required for the SmartPill to travel through the entire gastrointestinal tract and be present in the feces.


Secondary Outcome Measures:
  • Gastrointestinal Tolerance [ Time Frame: Day 4 ]
    Subjects scored their gastrointestinal tolerance based on 7 questions on a 0-10 scale on day 4 of each treatment period and the sum score was reported. 0 being the best and 10 being the worst. Each question has a value of 1-10 for a total of 70 points as value.

  • Food Intake Diary [ Time Frame: Day 1 ]
    Total dietary fiber consumed.


Enrollment: 10
Study Start Date: August 2009
Study Completion Date: April 2010
Primary Completion Date: April 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Low fiber and High Fiber
Subjects consume a low fiber cereal and swallow the SmartPill device that measures gastrointestinal transit time Subjects consume a high fiber cereal along with swallowing the SmartPill device that measures gastrointestinal transit time
Device: SmartPill
SmartPill

Detailed Description:
The ability of a device to track gastrointestinal transit time, including gastric emptying time, was measured in healthy people consuming low and high fiber diets.
