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.
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.

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The meeting reinforced clinical practices that have become increasingly established in recent years and also presented unpublished results on new microbiome-targeted therapies, in line with the summit’s central theme: “Diet and other ways to manipulate the gut microbiome in clinical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.
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.
The gut-kidney axis: How does the gut microbiota influence kidney health?
11 Mar 2026by Mónica Quinzo
Emerging evidence has revealed the biological dialogue between our kidneys and the trillions of bacteria inhabiting our gut, a connection scientists now call the gut-kidney axis. This connection is a complex feedback system in which the state of one organ can significantly affect the health of the other.
The ins and outs of the new Dietary Guidelines for Americans in light of the gut microbiome
