The Claim

In adults with Crohn’s disease, a reduction in fecal calprotectin during a plant-based diet is associated with changes in specific bacterial taxa, including a negative correlation with UCG.005 and positive correlations with Ruminococcus faecis and an unnamed Lachnospiraceae species, though these associations are weak and limited by high false discovery rates.

In plain English

In adults with Crohn’s disease, a decrease in fecal calprotectin while following a plant-based diet is linked to measurable changes in certain gut bacteria, including a decrease in UCG.005 and increases in Ruminococcus faecis and an unnamed Lachnospiraceae species, though these links are weak and may not be reliable due to statistical limitations.

Why this might work

Eating more plants feeds beneficial gut bacteria that make short-chain fatty acids, which strengthen the gut lining and calm immune activity in the intestine, leading to fewer immune cells entering the gut and less inflammation marker in the stool.

  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

    The study found that eating more plants helped reduce gut inflammation in people with Crohn’s disease and changed some gut bacteria — but it didn’t check the exact bacteria mentioned in the claim. Still, it doesn’t contradict the idea that these changes might be weakly linked.
