The secret to a long, healthy life? It's really very simple...

Giulia Crouch always knew there was something magical about the life of her Sardinian grandfather, so she was not surprised when Sardinia was identified as one of 5 'blue zones' around the world - places where people live healthy, happy lives for way longer than the average.

There are a host of reasons for the blue zoners' longevity but scientists agree it is their diet that matters most. They eat for flavour and pleasure: food that is nourishing without even trying.

In The Happiest Diet in the World, Giulia takes us to the culinary heart of these long-lived communities, where instincts and taste buds rule. With fascinating insights into everything from fasting to meat eating, sugar to wine-drinking, gut health and the incredible power of beans, this book shows us how to incorporate the key aspects of the blue zone diet into ours and how to reconnect with an instinctive wisdom which we are in danger of losing.
