Gut Health Boost: Mediterranean Diet Reduces Inflammation in Crohn’s Disease
If you have Crohn’s disease, this study suggests following a Mediterranean-style diet may be linked with lower inflammation and a gentler disease course, and it could positively change the gut microbiome and metabolites.
Adults with newly diagnosed Crohn’s disease; clinicians treating IBD; researchers studying diet–microbiome interactions.
What To Know
What to know This news item reports results from a prospective cohort study of 271 newly diagnosed Crohn’s disease patients that looked at Mediterranean diet (MED) adherence, clinical disease course, inflammatory markers, and multi-omic gut microbiota/metabolite profiles.
The article says higher MED adherence was linked with a milder disease course, lower C-reactive protein (CRP) and faecal calprotectin levels, increases in beneficial bacteria such as Faecalibacterium, and higher levels of short-chain fatty acids and plant-derived metabolites.
Lower adherence was associated with species described as potentially harmful (Escherichia coli, Ruminococcus gnavus) and higher primary bile acids and inflammatory metabolites. The authors and the news piece note that randomised controlled trials are needed to confirm whether the Mediterranean diet can be used therapeutically for Crohn’s disease.
Who should pay attention Adults with newly diagnosed Crohn’s disease, clinicians managing diet and inflammation in IBD, and researchers interested in diet–microbiome interactions.
More context This report describes an observational, prospective cohort with multi-omic analyses; such studies can show associations but cannot prove that the diet caused the improvements. The article and the original study call for randomised controlled trials to test MED as a treatment strategy.
The news summary is drawn from the journal reference provided in the article.
Observational cohort data show associations, not proof of causation. The study authors recommend randomised controlled trials before changing clinical practice.
