Investigative journalist Nina Teicholz joins us to discuss the critically important story of how natural saturated fats came to be demonized in the second half of the 20th century and how the promotion of polyunsaturated vegetable oils has helped ruin our health and dramatically and dangerously altered the nature of the products we see on the shelves of our supermarkets. Nina is the author of the international and New York Times bestselling book The Big Fat Surprise: why butter, meat and cheese belong in a healthy diet. If you saw the Time Magazine cover with the curl of butter on it not long ago…which was accompanied by the headline “Eat Butter”….that cover story was inspired by Nina Teicholz and her superb book.
