Fermentation is a hot craze in fancy restaurants around the world. And fermented foods, like kombucha and kimchi, are even sold in corner stores. Listeners of this show will have heard that fermented foods might benefit our gut health. But these foods make us uneasy. The idea of letting food rot, then eating it goes against everything our parents taught us. So, is fermentation scary and dangerous? This episode will show you why it's not only safe but beneficial to eat fermented foods, and that fermenting foods is something you can try at home. Jonathan speaks to Tim Spector and Sandor Katz — whom the food magazine CHOW calls a provocateur, trendsetter, and rabble-rouser — to better understand the fabulous world of fermentation.  Sandor Katz is a food activist who is widely credited with reintroducing fermentation to the US and the UK, calling himself a fermentation revivalist. Tim Spector is a co-founder at ZOE and one of the top 100 most cited scientists in the world.
