Summary

The study team's objective is to test the effect of supermarket discount levels on fruit and vegetable (F\&V) and non-caloric beverage purchasing and consumption, as well as health outcomes. The study team will implement this economic intervention in a local supermarket chain to assess the effects of a 32-week intervention of fruit and vegetable (F\&V) and non-caloric beverage discounts of 30%, 15%, and 0% (control group) on purchasing, dietary intake, and health outcomes, including body weight and composition, blood pressure, and biochemical markers of cardiovascular disease risk. The 32-week intervention will be preceded by an 8-week baseline and will have a follow-up period of 16 weeks. There will be no discounts in effect during the baseline and follow-up periods.
