The Impact of Free FV Provision on Household FV Intake.Primary· 4 weeks
We will test if levels of household FV intake change significantly over 4 weeks among participants randomized to the control condition, which includes free FV provision and a placebo (stress management) intervention not focused on food waste. FV intake will be measured with the FoodImage app. FV intake will be quantified as the total number of servings of FV eaten per day, with FV servings defined by United States Department of Agriculture (USDA) Food Patterns Equivalents Database (FPED).

The Impact of Free FV Provision on Levels of Household Food Waste, Measured in Grams.Primary· 4 weeks
We will test if levels of household food waste change significantly over 4 weeks among participants randomized to the control condition, which includes free FV provision and a placebo (stress management) intervention not focused on food waste. Food waste will be measured with the FoodImage app. Food waste will be quantified as total grams of food waste per day.

Change in Fruit and Vegetable Intake With Smart Intervention Compared to Pre-intervention BaselinePrimary· 4 weeks
Fruit and vegetable intake was assessed at baseline and post-intervention using data collected via the FoodImage app for three consecutive days prior to the first free fruit and vegetable pickup and three days following the final pickup. Intake was calculated in servings/day. Change is calculated as post-intervention value minus pre-intervention value, where positive values indicate an increase in intake and negative values indicate a decrease.

Change in Diet Quality (Healthy Eating Index) With Smart Intervention Compared to Pre-intervention BaselinePrimary· 4 weeks
Diet quality will be assessed using the Healthy Eating Index-2020 (HEI-2020), a validated tool that measures adherence to the Dietary Guidelines for Americans. Scores range from 0 to 100, with higher scores indicating better diet quality. The total HEI score is calculated based on intake data collected via the FoodImage app over a 3-day period before and after the 4-week Smart intervention. The intervention includes the free provision of fruits and vegetables (FV) and aims to reduce food waste and replace less healthy foods with FV.

Determine if a Smart Intervention to Reduce Food Waste and Replace Less Healthy Foods With FV Significantly Increases FV Plate Waste Compared to Pre-intervention Baseline.Primary· 4 weeks
We will test if levels of FV plate waste change significantly over 4 weeks among participants randomized to the control condition, which includes free FV provision and a placebo (stress management) intervention not focused on food waste. FV plate waste will be measured with the FoodImage app. FV plate waste will be quantified as total grams of food waste per day.

Determine if a Smart Intervention to Reduce Food Waste and Replace Less Healthy Foods With FV Significantly Reduces Household Level Food Waste, Measured in Grams, Compared to a Control Intervention.Primary· 4 weeks
We will test if a smart intervention to reduce food waste and replace less healthy foods with FV significantly reduces food waste over 4 weeks compared to a control (stress management) intervention. Both interventions include FV provision. Food waste will be measured with the FoodImage app. Food waste will be quantified as total grams of food waste per day.

Sponsor's own description
The primary aim of this study is to reduce household food waste and improve individual nutrition. This will be achieved using the FoodImageTM smartphone app 1, a novel method for measuring household food acquisition, food intake, and food waste decisions, to assess the efficacy of a smart intervention that targets food waste reduction and diet quality improvement. The intervention is designed to improve nutrition by offsetting intake of less nutritious foods with increased fresh fruit and vegetable (FV) intake while simultaneously reducing household food waste via strategies tailored to participating households.
