Summary

The goal of this experiment is to test the effects an "ultraprocessed" warning label on foods and beverages among Brazilian consumers. The main questions it aims to answer are:

* 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.
