Study of Dietary Composition in Crohn's Disease


Brief Summary

Patients with inflammatory bowel disease (IBD) often have narrowed microbial diversity and altered composition and function of the gut microbiome. We anticipate the anti-inflammatory diet, when compared with the usual diet, to produce favorable changes in these multi-omics profiles. These findings will provide insight into the interactions between diet and host biology, while providing clues on the mechanisms of diet therapy's effect and CD pathogenesis.
