Summary

This completed study tested whether adding environmental harm labels to fast-food menu items influences the healthfulness of people's meal choices. Over 7,000 U.S. adults completed an online survey where they ordered meals from two fast-food restaurants, with menus showing either control labels or eco-labels. Researchers measured the nutritional quality of the selected meals using a standard scoring system.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Environmental harm menu labels (behavioral intervention)
What this could lead to
If effective, these labels could help people make healthier fast-food choices by highlighting environmental impact.
What could go wrong
This was an online survey with hypothetical orders, not real-world behavior. Results may not translate to actual restaurant choices.
