À PROPOS DE CET ÉPISODE
In this episode of Longevity by Design, host Dr. Gil Blander sits down with Dr. Emeran Mayer, Executive Director at the UCLA Center for Neurobiology of Stress and Resilience and founder of Mayer Interconnected. They explore the science behind the gut-brain connection and its role in shaping health and longevity.
Emeran explains how signals flow between the brain, gut, and microbiome, influencing everything from digestion to emotions. He breaks down how modern diets, especially ultra-processed foods, disrupt the natural balance between humans and gut microbes—a relationship refined over thousands of years. The conversation highlights why early life exposure to antibiotics can have lasting effects on microbiome resilience, and how lifestyle choices like diet and exercise remain powerful tools for supporting gut-brain health at any age.
The discussion closes with a look toward the future of gut-brain science, including engineered probiotics and the promise of more targeted therapies. Emeran shares practical habits for better gut-brain health and cautions against quick-fix “biohacking,” encouraging a return to whole foods, movement, and mindful living.
