Can a diet tame Crohn's Flare-Ups? new trial investigates
NCT ID NCT05606419
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests two diet plans for adults with active Crohn's disease. One group follows the Crohn's Disease Exclusion Diet (CDED) with a liquid meal replacement, while the other adds dairy back early. The goal is to see if these diets can reduce symptoms and inflammation. The trial is currently suspended and involves 44 participants.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Crohn's Disease Exclusion Diet (CDED) with partial enteral nutrition or early dairy introduction
- What this could lead to
- If successful, this could offer a dietary approach to manage Crohn's disease symptoms and reduce inflammation without medication.
- What could go wrong
- This is a small, suspended trial with only 44 participants, so results may not apply widely. Dietary interventions can be hard to follow, and the study may not show clear benefits.
