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.
Crohn’s disease is an inflammatory bowel disease linked to an imbalance in the gut microbiome. Now, researchers at McMaster University have found in mice a way to target and 'turn off' only the bad gut bacteria using specially trained, precision viruses. This breakthrough paves the way for treatments tailored to each patient.
Struggling with constipation? Two bacteria in your gut microbiota may be to blame
8 Jul 2026by Cristina Sáez
A new study identifies two common gut microbes that work together to degrade mucin, a key lubricant for stool movement. This mechanism may explain why many treatments fail to provide lasting relief. The findings could pave the way for personalized therapies and new diagnostic biomarkers.
What do the soil under our feet, the pets in our homes, and the microbes in fermented foods all have in common? They are all part of the same vast microbial web, and they all help shape your gut.
Dietary fiber is often seen as essential for gut health. However, is it always beneficial? New research challenges this idea, highlighting that not all fibers act the same and that context, type, and dose matter.
What do we mean when we talk about the gastrointestinal system? Understanding the foundations of digestive health
26 May 2026by Giovana Martucelli
Digestive health goes beyond digestion. This overview revisits the gastrointestinal system, including how it functions, the role of the gut microbiota, and its connections with other organs in shaping overall health.
From diet to microbiome therapies: Key insights from the GMFH Summit 2026
19 May 2026by Manon Oliero, Giovana Martucelli, Andreu Prados
The 14th edition of the Gut Microbiota for Health World Summit brought together leading researchers from around the world to present the latest advances in the field. The meeting reinforced clinical practices that have become increasingly established in recent years and also presented unpublished results on new microbiome-targeted therapies, in line with the summit’s central theme: “Diet and other ways to manipulate the gut microbiome in clinical practice.”
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 gut microbiota “signature”: the key to the Mediterranean diet’s role in slowing cognitive decline
22 Apr 2026by Cristina Sáez
The Mediterranean diet is once again at the center of scientific evidence. A new study, published in BMC Medicine, shows that this dietary pattern not only protects cardiovascular and metabolic health, but also helps preserve cognitive function with age.
Intermittent fasting has become increasingly popular as a dietary approach for improving metabolic and gut health. This article explores the potential benefits and risks of intermittent fasting for the gut, examining current evidence on its effects on digestion, the gut microbiota, and overall health.
