He also documents the dietary trials of carbohydrate-restriction, which consistently show that the fewer carbohydrates we consume, the leaner we will be. He shows us how these unproven hypotheses were emphatically embraced by authorities in nutrition, public health, and clinical medicine, in spite of how well-conceived clinical trials have consistently refuted them. Taubes traces how the common assumption that carbohydrates are fattening was abandoned in the 1960s when fat and cholesterol were blamed for heart disease and then –wrongly–were seen as the causes of a host of other maladies, including cancer. (So apple juice or even green vegetable juices are not necessarily any healthier than soda.)īread and other baked goods, potatoes, yams, rice, pasta, cereal grains, corn, sugar (sucrose and high fructose corn syrup), ice cream, candy, soft drinks, fruit juices, bananas and other tropical fruits, and beer. The key is not how much vitamins and minerals they contain, but how quickly they are digested. These are from foods that stimulate excessive insulin secretion and so make us fat and increase our risk of chronic disease-all refined and easily digestible carbohydrates and sugars. Meat, fish, fowl, cheese, eggs, butter, and non-starchy vegetables. These foods can be eaten without restraint. These are from foods without easily digestible carbohydrates and sugars. Taubes argues persuasively that the problem lies in refined carbohydrates (white flour, sugar, easily digested starches) and sugars–via their dramatic and longterm effects on insulin, the hormone that regulates fat accumulation–and that the key to good health is the kind of calories we take in, not the number. Yet with more and more people acting on this advice, we have seen unprecedented epidemics of obesity and diabetes. In this groundbreaking book, the result of seven years of research in every science connected with the impact of nutrition on health, award-winning science writer Gary Taubes shows us that almost everything we believe about the nature of a healthy diet is wrong.įor decades we have been taught that fat is bad for us, carbohydrates better, and that the key to a healthy weight is eating less and exercising more.
