About

The purpose of this study is to assess the impact of non-sugar sweeteners (NSS) front-of-package labels (FOPL) on Brazilian parents' food and beverage selections for their children. The study includes three arms: 1. no NSS FOPL control group, 2. a group exposed to a NSS FOPL modeled after the Mexican warning label for NSS, and 3. a group exposed to a NSS FOPL using the magnifying glass symbol currently implemented in Brazil for nutrients of public health concern. Participants will be instructed to select products for their child, including one yogurt, three beverages (for breakfast, lunch, and dinner), one granola, and one cereal bar.
