The Importance of Gut Diversity and Balanced Nutrition

What if the key to preventing chronic disease, Alzheimer’s, and even depression lies not in your genes—but in your gut?

In this groundbreaking conversation, Louisa Nicola sits down with world-renowned epidemiologist and microbiome expert Professor Tim Spector (MD, King's College London, co-founder of ZOE) to unpack decades of research on the gut microbiome, nutrition, and how it shapes nearly every system in the body—including the brain.

You'll learn:

• Why identical twins with the same DNA can develop completely different diseases
• How gut microbes regulate immune responses, neurochemicals like GABA and serotonin, and even GLP-1
• The emerging connection between gut health and Alzheimer’s disease, stroke, and mood disorders
• Why probiotics often don’t work—and what to eat instead
• How menopause radically changes metabolism and gut diversity
• What 250,000+ people taught Tim about personalized nutrition and energy levels
• The 6 rules Tim lives by to radically improve gut (and brain) health

Whether you're a clinician, biohacker, or simply someone looking to upgrade your brain and body—this episode will fundamentally shift how you view food, mood, and longevity.
