You are what you eat, we've always been told, and indeed, food and diet have an enormous influence on your health and well-being. But as Graham Lawton reminds us here, eating the right amount of the right things—and not too much of the wrong things—isn't easy. Setting aside the myths and half-truths about food, this book will empower you to eat healthily, lose weight, and sort the fads from the science facts. A biochemist rather than a diet guru, Lawton lays out essential information on sugar, superfoods, and your gut microbiome, as well as fasting, veganism, and eating like a caveman.
