Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
* Do "ultraprocessed" warnings affect Brazilian consumers' intention to purchase products?
* Do "ultraprocessed" warnings affect Brazilian consumers' product perceptions?
Participants will see images of four products carrying either nutrient warning labels (which are currently mandatory in Brazil) or nutrient warning labels alongside an experimental warning label informing that the product is ultraprocessed. Participants will then answer survey questions about each product. Researchers will compare responses between both arms to determine if the "ultraprocessed" warning significantly changes the effect of nutrient warnings.
