San Diego put a smart spin on food stamp programs. For individuals families receiving government assistance, the Farmers’ Market Fresh Fund Initiative provides incentives for making healthy choices. Participants in the program can purchase Fresh Fund tokens (using cash or benefits cards), and the incentive basically doubles the tokens, giving them double the purchasing power, as long as they’re spending them on the healthy options at that market. Participants also complete surveys and share data, giving organizers a chance to analyze how active people are and share the statistics behind the success.
