Gut & MicrobiomeZOE's 34,000 microbiome study reveals which gut bacteria actually matter
Dr. Tim Spector discusses ZOE's landmark Nature paper analyzing 34,000 microbiome samples, revealing which gut bacteria species truly impact health. The conversation covers why gut diversity is a flawed metric, practical fermented food rankings, the TMAO pathway linking gut bacteria to cardiovascular risk, and the estrobolome's role in estrogen recycling. Spector explains why most probiotic supplements use outdated strains and provides actionable guidance on prebiotics, fiber intake, and building a healthier microbiome through consistent, moderate changes rather than dramatic interventions.
