Tim Spector on ferments, cheese and food packaging myths

from Well Enough

In this episode of Well Enough, we’re joined by the man who effectively pioneered the British gut-health revolution: Professor Tim Spector. As a leading genetic epidemiologist and the force behind ZOE, Spector has spent decades deconstructing why health outcomes are not all about genetics - it turns out our microbes are the ones calling the shots.Tim explains why a sanitized modern life is making us miserable and how the simple act of fermentation can act as a "vaccine" for the immune system. We’re talking about the "Four Ks" - Kefir, Kombucha, Kimchi, and Kraut - and why your expensive probiotic supplement might be a waste of money compared to a wedge of raw-milk cheese.Follow Well Enough on Instagram hereFollow Emilie on Instagram here 00:00 Introduction: Meeting Professor Tim Specter00:27 What is Fermentation?
