About this episode
There's an unseen world inside you, teeming with trillions of tiny inhabitants. Just like any ecosystem, some bugs inside your gut microbiome are beneficial, while others wreak havoc, quietly disrupting your health. What if these disruptive "invasive species" are silently driving the rise of cardiometabolic diseases, the leading cause of illness and death in Western countries? This episode reveals groundbreaking new ZOE research, soon to be published in Nature, that maps this hidden world. We’re joined by Professor Nicola Segata, the study’s co-author and a pioneer of this new technology, alongside ZOE's scientific Co-Founder, Professor Tim Spector, one of the world's top 100 most-cited scientists. Together, they reveal the top-ranked gut bacteria – both good and bad – that influence your health. Discover three powerful "good bugs" and how feeding them can suppress the "bad," transforming your gut ecosystem and paving the way for better health and potential therapeutic breakthroughs. Learn actionable tips for boosting your beneficial bacteria, starving the detrimental ones, and why gut testing is forever changed. 🥑 Make smarter food choices.
