Book excerpt: The author narrates his own journey to health, telling stories of how his parents saved each other's lives and how his wife Joanna overcame lupus. He explains why the science of nutrition is more settled than you think, suggests the best way to deal with doctors, takes on some leading historic opponents of the plant-based diet, blows apart the silly and misguided attacks on "carbs," and gives us an action plan to reverse the epidemics of obesity, diabetes, and heart disease, while obliterating demand for the kind of food-raising that risks future pandemics. Includes more than 100 delicious, vegan, whole-plant-food, oil-free, sugar-free, salt-free, gluten-free recipes.
