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The meeting reinforced clinical practices that have become increasingly established in recent years and also presented unpublished results on new microbiome-targeted therapies, in line with the summit’s central theme: “Diet and other ways to manipulate the gut microbiome in clinical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.”

For patients with celiac disease on a gluten-free diet, fiber may work best with the right gut microbes

The definition of a prebiotic has evolved from a focus on colonic fiber to a complex ecological strategy. This article traces the concept's 30-year journey, highlighting the shift from non-digestible carbohydrates to the latest expert recommendations.

Fiber and cancer prevention: what science says

26 Feb 2025

by Cristina Sáez

A new study reveals that consuming fiber-rich foods can play a crucial role in cancer prevention. The research shows that some products of fiber digestion by gut microbiota, such as butyrate and propionate, can alter gene expression and exert anti-tumor effects. These findings highlight the importance of including whole grains, vegetables, fruits, legumes, and nuts in our daily diet to support long-term health.

Could some multi-fiber bread a day keep the cardiologist away?

Diet variety is related to gut microbiome diversity and a greater abundance of some potentially beneficial bacteria. A new study suggests how increasing the quantity and diversity of dietary fiber intake by consuming multi-fiber bread may improve cholesterol and insulin resistance by altering gut microbiome composition and function.

Fermented foods show potential in increasing gut microbial diversity and modulating immune responses

Fermented foods, such as yogurt, kefir, kimchi and kombucha, have gained increasing popularity on the market shelves and consumers’ basket. Scientists at Stanford University elucidate how fermented foods may alter gut microbiota profile and reduce inflammatory markers.

How dietary fiber leaves its mark within the gut: Just 2 weeks are enough for dietary fiber to influence microbial metabolism

27 Sep 2021

Our diet has a huge influence not only on gut microbiota composition but also on its functions. New findings show a fiber-enriched Mediterranean-like diet is well tolerated and influences microbial metabolism in just two weeks, despite no major changes in the core microbiota composition.

Why the quality of your diet is the best recipe for a healthier gut microbiota and better health

The gut microbiota is largely shaped by what you eat. Recently, a large study involving more than 1,000 people showed that a balanced and nutritious diet supports a healthier gut microbiota and better health, while a diet full of highly processed foods with added sugar and salt promotes a gut microbiota linked to poor metabolic health.

A healthy gut for a healthy heart? A 10-year study looks at the gut-heart connection

17 Feb 2021

by Megan Mouw

A new study suggests that the gut microbiota may be a novel avenue for exploring heart disease prevention. This article explains how a diet higher in plants and lower in animal products may decrease heart disease risk thanks to the reduction in certain metabolites produced by the gut microbiota.
