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.
