This study examined the role of price on purchases of low-fat snacks from vending machines.
Sales of low-fat and regular snacks were monitored in nine vending machines during a 4-week baseline, a 3-week intervention in which prices of low-fat snacks were reduced 50%, and 3 weeks postintervention.
The proportion of low-fat snacks purchased was 25.7%, 45.8%, and 22.8% in the three periods, respectively.
Total snack purchases did not vary by period.
Reducing relative prices may be effective in promoting lower-fat food choices in the population.
Vending machines may be a feasible method for implementing such nutrition interventions.
