Objective
The study evaluated changes in household food intake, the waste of fruits and vegetables (FV), and FV inventories after supplemental produce was provided free of charge and in response to a smart coaching intervention to reduce food waste and replace less nutritious foods with FV.
Design
Households measured food intake and waste for ≥3 days before and after intervention. Households were randomized to receive either an intervention to reduce food waste and replace less healthy foods with FV or a control intervention. Both groups received free FV and measured FV inventories before and after intervention.
Setting
Participants were from the Baton Rouge, Louisiana region and picked up FV at a central location.
Participants
46 adults and their household members.
Results
Treatment participants increased intake of fruits (0.33 servings/day, p=0.09) and vegetables (0.50 servings/day, p=0.01) compared to the control group. All participants reported a decrease in daily total caloric intake (133 kcal/day, p=0.04), an increase in the number (9.5 events/period, p<0.001) and average magnitude (100.5 g/event, p=0.005) of FV waste events, and an increase in fresh FV inventories (4.1 kg/household, p=0.001) after receiving free FVs. Compared to the control group, treatment participants reported less FV waste during eating occasions (22.2 g/day, p=0.09) and an increase in frozen FV inventories (1.8 kg/household, p=0.04).
Conclusions
Providing free FVs without additional intervention does not increase FV intake but does lead to more and larger FV waste events. When coupled with targeted information to improve diet quality and reduce waste, free FV provision can lead to increased FV intake with no significant increase in energy intake or plate waste and smaller increases in the number and magnitude of FV waste events, suggesting that pairing intensive intervention efforts with free FV provision is critical to translate program resources into improved nutrition without increasing waste.
