The ultimate myth-busting nutrition bible. Registered dieticians and qualified nutritionists Rosie Saunt and Helen West are the founders of The Rooted Project, set up to translate the latest research direct to your plate, and make evidence-based nutrition accessible and engaging. In this book, they explore everything from the danger of anecdotal evidence and unsubstantiated 'facts' about food to the real science behind the nutrients we consume every day. They explain why there's nothing to be feared from fat or carbs, or - for the vast majority of us - the much-maligned gluten, as well as probing the murky depths of the diet industry to explore the latest links between diet culture and weight stigma. They take a deep-dive into gut health, look at the emerging science of the connection between food and mood and examine differences between allergies and intolerances. This book is both a reference guide and a narrative to relish: it debunks the myths that dominate the food and wellness industry and offers the right tools and knowledge to allow readers to take control of their own health. Evidence-based, body positive and practical, IS BUTTER A CARB? is the modern must-have nutrition book for everybody interested in food, health and pop science.
