The Gut Truth

The modular kitchen: what actually works for your digestion, according to science.

Do you really need to detox? Does gluten cause inflammation? Do probiotics actually work? We're surrounded by contradictory advice about food and gut health. This book gathers the most current scientific evidence to help you separate fact from marketing. Inside you'll find: • What we actually know about the gut and the microbiome. • The most common myths about detox, gluten, probiotics and other popular topics. • How to interpret scientific evidence without falling for fads. • A practical modular cooking system with 25 combinations to apply the book's concepts in everyday life.

About the author

Gepetto Perin

I'm a biochemist with a PhD in Chemical Sciences, which is a formal way of saying I spent my career learning to tell a real result from one that just looks convincing. But I didn't write this book from a lab: I wrote it from the family table. Every scientific claim in these pages is cited to a real study you can check. That's the whole point. This is the book I wish had existed: for anyone who loves food, distrusts marketing, and just wants to know what's true.
