Access to healthy food. Increasing access to healthy foods is a key component of improving the food environment, yet, adding supermarkets or changing the existing store resources (e.g., adding refrigerated units to accommodate fruits and vegetables) can takes years to perform and are often expensive. Additional options, such as farmer's markets and urban gardening, can be limited by their seasonal nature and may have differential patterns of use in different areas of the U.S. To provide immediate, affordable, and easy access to healthy choices, we selected providing access in the form of a van (Fresh Truck) that sold fruits and vegetables to residents of public housing. The van visited each intervention housing development weekly. HLAs at each development promoted the van's offerings and were present while the Fresh Truck was parked on-site.
