Good Calories, Bad Calories.pdf
For 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. Yet despite this advice, we have seen unprecedented epidemics of obesity and diabetes. Taubes argues that the problem lies in refined carbohydrates, like white flour, easily digested starches, and sugars, and that the key to good health is the kind of calories we take in, not the number. In this groundbreaking book, award-winning science writer Gary Taubes shows us that almost everything we believe about the nature of a healthy diet is wrong.
“Taubes’s eye-opening challenge to widely accepted ideas on nutrition and weight loss is as provocative as was his 2001 NewYork Times Magazine article, What if It’s All a Big Fat Lie? Taubes (Bad Science), a writer for Science magazine, begins by showing how public health data has been misinterpreted to mark dietary fat and cholesterol as the primary causes of coronary heart disease. Deeper examination, he says, shows that heart disease and other diseases of civilization appear to result from increased consumption of refined carbohydrates: sugar, white flour and white rice. When researcher John Yudkin announced these results in the 1950s, however, he was drowned out by the conventional wisdom. Taubes cites clinical evidence showing that elevated triglyceride levels, rather than high total cholesterol, are associated with increased risk of heart disease-but measuring triglycerides is more difficult than measuring cholesterol. Taubes says that the current U.S. obesity epidemic actually consists of a very small increase in the average body mass index. Taube’s arguments are lucid and well supported by lengthy notes and bibliography. His call for dietary advice that is based on rigorous science, not century-old preconceptions about the penalties of gluttony and sloth is bound to be echoed loudly by many readers. ” – Publishers Weekly
“Noted science journalist Taubes probes the state of what is currently known and what is simply conjectured about the relationship among nutrition, weight loss, health, and disease. What Taubes discovers is that much of what passes for irrefutable scientific knowledge is in fact supposition and that many reputable scientists doubt the validity of nutritional advice currently promoted by the government and public health industry. Beginning with the history of Ancel Keys’ research into the relationship between elevated blood-cholesterol levels and coronary heart disease, Taubes demonstrates that a close reading of studies has shown that a low-cholesterol diet scarcely changes blood-cholesterol levels. Low-fat diets, moreover, apparently do little to lengthen life span. He does find encouragement in research tracking the positive effects of eliminating excessive refined carbohydrates and thus addressing pernicious diseases such as diabetes. Taubes’ transparent prose brings drama, excitement, and tension to even the most abstruse and clinically reserved accounts of scientific research. He is careful to distinguish the oft-confused goals of weight loss and good health. Given America’s current obsession with these issues, Taubes’ challenge to current nutritional conventional wisdom will generate heated controversy and create popular demand for this deeply researched and equally deeply engaging treatise.
