AN INSTANT NEW YORK TIMES BESTSELLER

“Everything you ever wanted to know about the gut (and then some).”
—SELF

Discover the secrets of your digestive system—and how to hone a healthy gut—plus new research on the mind-gut connection.

With quirky charm, science star and medical doctor Giulia Enders explains the gut’s magic, answering questions like: What’s really up with gluten and lactose intolerance? How does the gut affect obesity? What's the connection between our microbiome and mental health? Why does acid reflux happen? In this revised edition of her beloved bestseller, Enders includes a new section on the brain-gut connection, and dives into groundbreaking discoveries of psychobiotics—microbes with psychological effects that can influence mental health conditions like depression and even stress.

For too long, the gut has been the body’s most ignored and least appreciated organ. But it does more than just dirty work; it’s at the core of who we are, and this beguiling book will make you finally listen to those butterflies in your stomach: they’re trying to tell you something important.
