What is the purpose of this trial?

This trial aims to reduce household food waste and improve nutrition by encouraging increased consumption of fruits and vegetables. Participants will use a smartphone app called FoodImage to track their food habits, including shopping, preparing, eating, and wasting food. One group will receive guidance on managing food waste and improving diet quality through the Smart Intervention for Food Waste Management and Replacing Current Diet with Fruits and Vegetables. Another group will focus on stress management through the Smart Intervention for Stress Management. Individuals who handle most of the food shopping and cooking at home and own an iPhone might be a good fit for this study. As an unphased trial, this study offers a unique opportunity to contribute to innovative research on nutrition and food waste management.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that managing food waste by replacing less nutritious foods with fruits and vegetables is safe. Studies have found that providing free fruits and vegetables to households improves diet quality without negative effects. This method uses the FoodImageTM app to track and reduce food waste while increasing the consumption of healthy foods like fruits and vegetables.

No harmful side effects have been reported from this approach. Instead, studies highlight benefits such as improved nutrition and reduced food waste. As a behavioral change rather than a medical treatment, it is generally easy to follow. Participants simply use the app to enhance their eating habits. There are no known risks, making it a safe and practical choice for those wanting to eat healthier and reduce waste. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about this trial because it explores innovative ways to improve diet quality and manage stress through smart interventions. Unlike traditional dietary advice that often focuses solely on calorie counting, this trial uses a FoodImage app to track food acquisition, preparation, consumption, and waste, aiming to enhance awareness and reduce food waste. Additionally, both groups receive free fruit and vegetable boxes, encouraging healthier eating habits without increasing calorie intake. This dual focus on food waste management and stress management offers a holistic approach to improving overall health and wellness.

What evidence suggests that this trial's interventions could be effective for reducing food waste and improving nutrition?

Research shows that the FoodImageTM app can help people eat more fruits and vegetables while reducing food waste. In this trial, the Food Waste Intervention Group will receive guidance on managing food waste and replacing foods to improve diet quality. Studies have found that mobile apps can encourage healthier eating habits by increasing fruit and vegetable intake. Additionally, a smart coaching program focused on reducing food waste and replacing less healthy foods has been linked to better diet quality. Meanwhile, the Stress Management Control Group will receive guidance on stress management. Another study found that providing free produce to households can change eating habits, leading to less waste and more fruits and vegetables at home. This evidence supports the idea that smart dietary programs can effectively improve nutrition and reduce food waste. ^{1 4 6 7 8}

What Are the Treatments Tested in This Trial?

Interventions

• Smart Intervention for Food Waste Management and Replacing current diet with Fruits and Vegetables
• Smart Intervention for Stress Management

Trial Overview

The study tests a smart intervention using the FoodImageTM app to reduce food waste at home and improve diet by increasing fruit and vegetable intake. Participants will receive tailored strategies to help them make better nutritional choices while minimizing waste.

How Is the Trial Designed?

Group I: Food Waste Intervention Group Active Control 1 Intervention

This group will receive an intervention on food waste management and fruit and vegetable replacement to increase diet quality while avoiding an increase in calories. Both groups will obtain free fruit and vegetable boxes and will use the FoodImage app to record food acquisition (Shop), food prep (Prep), intake (Eat) and waste (Toss) for approximately 3 (24 hour) days; ideally including 1 weekend date.

Group II: Stress Management Control Group Placebo Group 1 Intervention

This group will receive an intervention on Stress Management and will be intensity matched to the treatment group. Both groups will obtain free fruit and vegetable boxes and will use FoodImage to record food acquisition (Shop), food prep (Prep), intake (Eat) and waste (Toss) for approximately 3 (24 hour) days; ideally including 1 weekend date.

Published Research Related to This Trial

The mobile Food Record (mFR) method showed a significant correlation between reported energy intake and total energy expenditure, indicating its accuracy in dietary assessment among 45 participants over 7.5 days.

Participants found the mFR easy to use, and it performed comparably to traditional dietary records, with no systematic biases detected in the data collection process.

A 3-week hospital-based cooking and gardening program for children aged 8-15 in Seattle showed promising results, with 100% of participants cooking at home and 78% gardening at home one year later.

This program demonstrates the feasibility of using integrated cooking and gardening interventions as effective strategies for promoting healthy eating habits among children and their families.

Culinary interventions, such as cooking classes, did not significantly change cardiometabolic risk factors like body mass index, blood pressure, or LDL cholesterol in a review of 30 studies involving 7381 participants.

However, these interventions were effective in improving participants' attitudes, self-efficacy, and dietary intake, especially when combined with additional components like nutrition education or physical activity.

The Healthy Teaching Kitchen (HTK) program, implemented by the Veterans Health Administration, has been found to be acceptable and feasible for veterans, providing interactive nutrition and culinary education.

Participants in the HTK program reported increased self-efficacy for making dietary changes, suggesting that the program empowers veterans to improve their dietary and cooking habits, potentially leading to better health outcomes.
