Supplemental Nutrition Assistance Program healthy eating incentives and fruit and vegetable spending across the month.

Objective: To estimate how incentives that encourage healthy eating among Supplemental Nutrition Assistance Program (SNAP) participants impact intra-monthly variation in fruit and vegetable spending.

Design: We used transaction data from three Alabama grocery stores participating in a programme that offered dollar-matching coupons for fresh produce. For each store, we calculated daily spending on fresh produce out of SNAP benefits and daily incentive coupon redemptions.
