It's America's favorite addiction: caffeine, and coffee. We chat with Murray Carpenter, author of the new book Caffeinated. He traveled the world in search of caffeine sources to find out exactly how much caffeine is in our coffee, our chocolate, and why it's so lightly regulated (This is not an attack on coffee -- he remains an addict!).
Later on, we broaden the conversation with two studio guests: Kathy Turiano from Joe Bean Coffee Roasters and Sarah Guilbert, registered dietician for UR Medicine.
