Once misunderstood, and often overlooked, ferments are now recognised as some of the most beneficial foods we can eat. From kombucha and kefir to sourdough, miso and coffee, Tim explains what fermented foods are, what to look for when buying them, how to make them at home, and how adding simple ferments to everyday meals can transform your gut health and overall well-being.

Blending cutting-edge science with practical, reassuring advice, Ferment shows how small changes to what’s on your plate can make a big difference to your health.
