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 you’ve been denying yourself are themselves the key to reversing the epidemics of obesity, diabetes, and heart disease?

Based on a nine-year-long investigation, author Nina Teicholz shares 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 joins Dr. Friedman to explain why the Mediterranean Diet is not the healthiest, and how we might be replacing trans-fats with something even worse.

The startling history on diet and nutrition, outlined in Nina's new book, The Big Fat Surprise, 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.
