It’s an issue of mind over matter for health journalist Tyler Graham and assistant clinical professor of psychiatry at Columbia University Dr. Drew Ramsey. Everyone agrees that the modern American diet (or the MAD, according to the authors) makes people fat. But the authors also argue that the nation’s unhealthy food is “undermining our emotional and mental well-being” and is “largely responsible for skyrocketing levels of brain disorders.” The book points out which foods lead to depression and anxiety, and it suggests antidotes such as grass-fed beef, butter, yogurt and whole milk to better your mood. By changing what you eat, say the authors, you can “stabilize your moods. You can improve your focus. You can even make your brain grow.” And you thought doughnuts made you happy?!
