Should foods considered "unhealthy" be taxed in order to subsidize the purchase of healthy foods? Are setting new dietary guidelines enough to help the public make healthier choices? How can we prevent food deserts and give more people access to healthy foods? From pioneering work on the SNAP program in the U.S. and the development of a Public Impact Initiative at the school, to guiding policy in the international food system; our faculty, students, and alumni possess the skills and passion to make a real impact on the food environment. Our work becomes all the more urgent as populations who need the most help are at highest risk for developing chronic disease.
