A Single-center Open-label Study to Determine the Effect of Diet on Microbiome Signatures in Crohn's Disease Patients

Case Western Reserve University·interventional·Posted Aug 22, 2019·Updated Jun 3, 2026

In Brief

A clinical study evaluating Soy based diet and Non-soy based diet for Crohn Disease. Completed, enrolled 67 participants across 1 site.

Detailed Summary

This protocol is designed to compare the effectiveness of a soy-based diet or identical diet without soy given to patients with Crohn's disease (CD) in remission, patients with active CD, or healthy controls. The assigned diet will be compared to participant 'baseline' (pre-diet) in terms of its ability to change the gut bacteria and fecal butyrate, an important short-chain fatty acid (SCFA) that limits bowel inflammation, a characteristic of this debilitating disease.
