Speaking during a visit to Barcelona, Professor John Cryan discusses new findings showing that coffee polyphenols may support microbial communities involved in gut-brain communication—and why decaffeinated coffee produced similar effects.

Molecular Psychiatry - Towards ecological psychiatry: The herbicide glyphosate disrupts behavior through microbiota-gut-brain axis

This Perspective emphasizes the necessity of expanding microbiome–gut–brain axis studies into low- and middle-income countries, highlighting potential insights into mental health and environmental interactions, while addressing ethical responsibilities and the need for diverse global health interventions.

Per- and polyfluoroalkyl substances (PFAS) are persistent xenobiotics linked to neurodevelopmental, neurodegenerative, and neurological disorders. PFAS-induced gut microbiota remodelling may disrupt gut-brain signalling, thereby affecting brain functions and behaviour. Integrating microbiome endpoints (diversity, taxonomic shifts, and metabolic configuration) into PFAS research provides a framework to elucidate toxicodynamic mechanisms and to inform the development of targeted, mechanism-based therapeutic strategies.

Discover how both caffeinated and decaffeinated coffee might affect the gut–brain axis through changes in the microbiome, influencing mood, cognition, stress, and overall wellbeing.

This Review provides an overview of the interplay between host diet and the gut microbiota, and how this affects brain function.

​For more than two decades, scientists have uncovered remarkable links between the trillions of microbes living in our gut and the health of our brains. What if much of this science is based on studyi...

(Beyond Pesticides, July 17, 2026) It is now well established that frequent exchange of signaling between the brain and the gut is a crucial feature of human mental and physical health. External chemicals introduced through the digestive system affect the gut microbiome, which in turn influences the brain. Perhaps the most ubiquitous and pernicious bad actor in the large cast of pesticides shown to disrupt the gut-brain axis is the weed killer glyphosate. A team from the University of Cork in Ireland has published an innovative study whose results, while subtle, reaffirm that pesticides,...
