Produce Prescription Dose Response: A Randomized Community Trial

A randomized trial comparing monthly produce prescription doses of $40, $80, and $110 among 242 predominantly Hispanic women found that higher benefit amounts led to better outcomes across the board. Participants receiving $110/month showed significantly greater fruit and vegetable intake, improved food security, and higher benefit redemption rates compared to those receiving $40/month — suggesting a clear dose-response relationship. These findings highlight benefit amount as a critical program design decision, with higher doses more likely to drive meaningful improvements in diet quality and food security.
