In May 2018, the U.S. government will be rolling out broad new menu labeling regulations. As part of the Affordable Care Act, restaurants and other food outlets with more than 20 locations will be required to post calorie counts right on their menus. And new research shows those rules may already be having an impact before they even go into effect. A study led by Sara Bleich, professor of public health policy, shows that many large chain restaurants have started removing higher calorie items from their menus. In this week's episode, we speak with Bleich about what these changes could mean for America's fight against obesity—and how policy changes can be used to alter the country's unhealthy food environment.
