Investigative journalist Nina Teicholz reveals the unthinkable: that everything we thought we knew about dietary fats is wrong. She documents how the past sixty years of low-fat nutrition advice has amounted to a vast uncontrolled experiment on the entire population, with disastrous consequences for our health.
For decades, we have been told that the best possible diet involves cutting back on fat, especially saturated fat, and that if we are not getting healthier or thinner it must be because we are not trying hard enough. But what if the low-fat diet is itself the problem?What if those exact foods we’ve been denying ourselves — the creamy cheeses, the sizzling steaks — are themselves the key to reversing the epidemics of obesity, diabetes, and heart disease?
In this captivating and convincing narrative, based on a nine-year-long investigation, Teicholz shows how the misinformation about saturated fats took hold in the scientific community as well as the public imagination, and how recent findings overturn these beliefs. She explains why the Mediterranean Diet is not the healthiest, and how we might be replacing trans-fats with something even worse. This startling history demonstrates how nutrition science has gotten it so wrong: how overzealous researchers, through a combination of ego, bias, and premature institutional consensus, have allowed dangerous misrepresentations to become dietary dogma.
