Cure8 research brief
Diet is a modifiable factor that appears to change the gut microbiome and may affect symptoms and inflammation in both IBS and IBD; understanding which patterns help could guide practical dietary advice.
Adults with IBS or IBD, clinicians who manage these patients, researchers studying diet–microbiome interactions, and patients interested in dietary approaches to symptom control.
This is a narrative review summarizing evidence on how diet shapes the gut microbiome and influences IBS and IBD.
The authors report that Mediterranean and plant-forward diets are consistently associated with enrichment of short-chain fatty acid–producing taxa (for example Faecalibacterium and Roseburia), lower systemic inflammation, and better clinical outcomes in studies they reviewed.
They note the Low FODMAP diet reduces IBS symptoms but often produces modest or inconsistent changes in microbial composition. By contrast, Western and ultra-processed diets are linked to dysbiosis, loss of beneficial taxa (including Akkermansia), increased intestinal permeability, and pro-inflammatory signals.
The review calls for integration of dietary counseling into care and for long-term randomized controlled trials that combine microbiome profiling with clinical endpoints to enable personalized, microbiota-targeted nutritional strategies.
This article is a review (structured content depth: abstract) summarizing existing studies rather than reporting a single new trial. The review recommends more long-term randomized trials with microbiome and clinical outcomes; it does not provide definitive treatment guidelines.
Individual diet responses vary, and dietary changes should be discussed with a clinician or dietitian.
