ABSTRACT
OBJECTIVE:
The objective of this study was to assess purchasing, intake, and weight after discounting fruits and vegetables (F&V) and noncaloric beverages in New York City supermarkets.METHODS:
A 16-week randomized controlled trial was conducted with a 4-week baseline, an 8-week intervention with 50% discounts on F&V and noncaloric beverages, and a 4-week follow-up. Purchasing was tracked via loyalty cards, and intake was tracked via 24-h dietary recalls. Weights were measured at five in-person visits.RESULTS:
Data from 67 participants were analyzed (38 in the experimental group; 29 in the control group). F&V and noncaloric beverage weekly purchasing was greater in the experimental than the control group (mean difference [SD], $4.64 [$1.44], p < 0.0001; $0.53 [$0.39], p = 0.008) during intervention, with F&V purchasing remaining greater in the experimental versus control group during follow-up (p = 0.005). F&V intake was greater for the experimental than the control group during intervention (142 [105] g/day; p = 0.009) and follow-up (p = 0.001). Although no difference in noncaloric beverage consumption was observed between groups, there was lower alcohol intake in the experimental than the control group during follow-up (-85.8 [60.2] g/day; p = 0.004). The experimental group lost weight compared with the control group (-1.33 [0.92] kg; p = 0.006 intervention and p = 0.106 follow-up). No differences in nutrient composition or high energy-dense product consumption were found.CONCLUSIONS:
A 50% discount on F&V and noncaloric beverages promoted increased purchasing and intake of F&V and induced weight loss.
