Alterations in the composition and function of the gut microbiota are recognized as key contributors to the pathophysiology of IBS. In this interview with Prof. Carmelo Scarpignato, we discuss the knowns and unknowns of gut microbiota in IBS, the four levels of gut microbiota manipulation, and examples of microbiota-targeted approaches available for the clinician.
Bifidobacteria are increasingly studied as a marker of gut health across a lifetime. In this interview, microbiome researcher Sudarshan Shetty explains what shapes them, how they change with age, and what diet can do.
Rethinking diet and the gut microbiome in IBD: from risk to treatment and beyond
28 May 2026by GMFH Editing Team
The role of diet and the gut microbiome in inflammatory bowel disease (IBD) continues to evolve, from shaping disease risk to supporting treatment strategies. In this interview with Richard Hansen and Chen Sarbagili, we discuss key misconceptions, emerging evidence, and what the future may hold for microbiome-based approaches in IBD.
The benefits of fiber in celiac disease may depend on having the right bacteria in the gut
15 May 2026by GMFH Editing Team
The gluten-free diet for celiac disease can be low in fiber. Researchers from McMaster University showed that people with celiac disease had reduced capacity to metabolize dietary fiber in the small intestine because they lack key fiber-degrading bacteria.
The management of disorders of gut-brain interaction based on their causes was a central topic addressed at NeuroGASTRO 2025. In this video interview, Dr. Javier Santos delves into the role of mast cells in postprandial symptoms and the present and future of microbiome-based interventions for bowel disorders.
