77. Professor Tim Spector: Your Gut Bacteria Control Your Health More Than Your DNA


Listen Later

Your doctor says your health problems are genetic, so you're destined for the same fate. But what if that's completely wrong?

In this episode of Extend, I'm joined by Professor Tim Spector, one of the world's leading microbiome researchers, to reveal the truth: your gut bacteria have more control over your health than your genes do.

We explore Tim's 30-year twin study that turned modern medicine upside down, the devastating effects of antibiotics on your internal ecosystem, and why ultra-processed foods are as dangerous as cigarettes. We also dive into why 95% of Americans are dangerously fiber-deficient, and how fermented foods can reduce inflammation like natural steroids.

 

Professor Tim Spector is a genetic epidemiologist at King's College London, co-founder of Zoe, and author of multiple bestselling books on the microbiome. His research on 16,000 twins has revolutionized our understanding of how gut health trumps genetics in determining health outcomes.
