Brief Summary
The primary objective of this study is to evaluate whether repeated exposure to environmental harm menu labels on fast-food restaurant menus improves the healthfulness of real-world fast-food meal orders. Participants will be randomized to view either a control (QR code) label or traffic-light style environmental harm labels on two alternating fast-food restaurant menus, and will order one lunch per week for seven weeks through a study ordering website, with each meal delivered to the participant the following day.
