The Claim

A 12-week plant-based diet in adults with Crohn’s disease is associated with increased abundance of Faecalibacterium and Bacteroides, two bacterial genera consistently depleted in inflammatory bowel disease, suggesting a shift toward a microbiota profile linked to improved gut health.

In plain English

In adults with Crohn’s disease, following a plant-based diet for 12 weeks is associated with higher levels of Faecalibacterium and Bacteroides bacteria, which are typically lower in people with inflammatory bowel disease.

See the scientific wording

A 12-week plant-based diet in adults with Crohn’s disease is associated with increased abundance of Faecalibacterium and Bacteroides, two bacterial genera consistently depleted in inflammatory bowel disease, suggesting a shift toward a microbiota profile linked to improved gut health.

Why this might work

Eating more plants sends undigested fibers and plant compounds into the gut, where bacteria feed on them and produce short-chain fatty acids. These fatty acids strengthen the gut lining, block harmful substances from leaking out, and calm immune cells in the intestine. This reduces inflammation and allows beneficial bacteria to thrive.

  1. Study: Modulating the gut microbiota in Crohn’s disease: a pilot study on the impact of a plant-based diet with DNA-based monitoring

    People with Crohn’s disease who ate more plants for 12 weeks ended up with more of two helpful gut bacteria—Faecalibacterium and Bacteroides—that are usually low when the gut is inflamed. This suggests their gut health improved.
