As obesity has come to the forefront of public health concerns, there is growing interest in finding ways to guide consumers' food choices to be more beneficial for their long-term health.

This study uses behavioral economics, food marketing, and psychology to identify possible options for improving the diets and health of participants in the Food Stamp Program, the Special Supplemental Nutrition Program for Women, Infants and Children (WIC), and the National School Lunch and School Breakfast Programs.
