Brief summary: Purpose: The overall purpose of this study is to identify the impacts of an ultra-processed (UPF) health warning label and UPF identify warning label compared to a control label (i.e., a barcode).

Participants: \~4,000 US Latino adults of parental age (18-55 years), approximately 50% of whom will have limited English proficiency, recruited from a Latino-focused panel company.

Procedures: Participants will be randomly assigned to view food products with one of three label types: health warning labels, identity labels, or barcode control labels. Participants will be asked a series of questions about the products and the label they were assigned.

Detailed description: On the study platform (Qualtrics), participants will be randomly assigned to 1 of 3 arms with equal probability: a UPF health warning label, a UPF identity label, or a barcode control label. Participants will view four products (a fruit-flavored drink, pretzels, a yogurt, and a breakfast cereal) displayed in random order, each with a label displayed on the front of package according to the participants' study arm. Participants will complete a 13-item online survey to assess each product as to a) whether the product is ultra-processed; b) perceptions of healthfulness; c) intentions to purchase the product.
