Summary

This study tested whether adding a warning label that says a product is ultraprocessed changes how Chilean parents view and intend to buy these foods. Over 3,600 parents were shown similar products with or without the extra label. Researchers measured purchase intentions and whether people correctly identified the foods as ultraprocessed. The goal is to see if such a label could help consumers make more informed choices.
