Green beans tested as first fiber food for short gut patients
NCT ID NCT06240065
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
Short bowel syndrome is a rare condition where the bowel is too short to absorb enough nutrients. This study gives green bean puree to 60 adults with and without the condition to see if they can tolerate fiber. Researchers will track symptoms, weight, and changes in gut bacteria to learn how fiber affects digestion.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Green bean puree
- What this could lead to
- If successful, this could help doctors understand how to safely introduce fiber into the diets of people with short bowel syndrome, potentially improving nutrition and gut health.
- What could go wrong
- This is a small, early-stage study with only 60 participants. It is not testing a treatment or cure, and results may not apply to everyone with short bowel syndrome.

Inclusion Criteria: * Actively follows at UTSW outpatient clinics * SBS arm specific: History of SBS diagnosis. History of short bowel syndrome based on surgical/imaging records. Small bowel is in continuity with some portion of colon * Control arm specific: No history of intestinal pathologies * No or negligible amount (few bites of fiber-containing foods okay) of fiber in tube feeds or by mouth at baseline * Less than 20% calories from oral food not containing fiber while the other 80% may be by enteral and/or parenteral feedings * At least 20% calories from fiber-free formula taken orally or via tube * Antibiotic use is allowed, however, should be on a stable regimen of antibiotics starting from 2 weeks prior to intervention until end of study or end of week 3 whichever is sooner * Previous history of fiber introduction failure is acceptable as long as clinically stable at the time of recruitment * Fiber supplementation is appropriate per primary physician Exclusion Criteria: * SBS Arm specific: No diagnosis of SBS. * Control Arm specific: has baseline intestinal diseases * Small bowel and colon not in continuity (Ex: presence of ileostomy or jejunostomy) * \>5% changes in percentage of calories from PO, EN and/or PN during the intervention * Addition/discontinuation/significant alteration to antibiotics regimen during study period * Primary physician does not think fiber supplementation is appropriate clinically
