Food Swaps for Healthy Eating
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores how health and climate labels in an online grocery store can influence food choices. Participants will encounter various labels or swap suggestions to guide them toward healthier or more climate-friendly foods. The goal is to determine if these suggestions, including combined health and environment swaps, lead to better health and a smaller carbon footprint compared to shopping without guidance. Individuals living in the U.S., with internet access, and the ability to complete an English survey may be suitable candidates. As an unphased trial, this study provides a unique opportunity to contribute to research that could enhance both personal health and environmental sustainability.
Do I need to stop taking my current medications for this trial?
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 shows that simple changes in food choices benefit both health and the environment. Studies have found that suggesting healthier food options, or "health swaps," helps people make better eating decisions. This approach is safe because it involves choosing different foods rather than introducing new substances or medications.
Similarly, "climate swaps" encourage selecting products that are better for the environment. Although less research exists on the safety of climate swaps, they focus on promoting eco-friendly choices without health risks.
When health and climate swaps are combined, research suggests they improve both personal health and environmental impact. These swaps are safe because they involve choosing different foods, not adding new ones.
Overall, participating in a study involving these swaps is considered safe. The goal is to educate and guide choices positively.12345Why are researchers excited about this trial?
Researchers are excited about this trial because it's exploring how simple food swaps can promote healthier eating, considering both health and environmental impacts. Unlike traditional dietary guidance that may focus solely on nutrition, this approach introduces "nutrition grades" and "climate grades" to food products. This dual perspective allows individuals to make informed choices that are better for their health and the planet. By suggesting alternatives that are superior in at least one grading aspect and not worse in the other, the trial aims to find out how these swaps can help people adopt more sustainable and nutritious diets.
What evidence suggests that this trial's treatments could be effective?
Research has shown that health swaps, like Nutri-Score labels, help people make healthier online shopping choices. For example, one study found that these swaps make healthier options more visible, leading to better nutrition choices. In this trial, participants may receive health swaps, climate swaps, or combined health and climate swaps. Climate swaps—such as choosing chicken instead of beef—can lower carbon footprints by up to 35% and also improve diets. Studies indicate that even simple swaps can have a significant environmental impact. Combining health and climate swaps enhances both nutrition and sustainability, allowing people to make choices that benefit their health and the planet. Specifically, these combined swaps have reduced carbon footprints and improved dietary health.678910

Treatment groups
Experimental Treatment
Active Control
Labels will be "nutrition grades" for products and replacement swap suggestions will be for items with a better nutrition grade.
Labels will be "nutrition grades" and "climate grades" for products and replacement swap suggestions will be for items that are better than originally selected products on at least one dimension (nutrition grade or climate grade) and not worse than originally selected products on either dimension.
Labels will be "climate grades" for products and replacement swap suggestions will be for items with a better climate grade.
No labels or swaps.
