NSS Grocery Store Brazil

Effects of a Non-sugar Sweetener Label on Parents' Selection of Foods and Beverages in Brazil: a Randomized Clinical Trial.

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.

Eligible participants include:

• Adults aged 20 years or older,
• Living in Brazil
• Parents or guardians of children between 2 and 12 years old
• Primarily responsible for the household grocery shopping (more than 50%)
• Can read and understand Portuguese

Recruitment will occur nationwide through an online panel, with quotas for education, race, and geographic distribution to approximate the national profile.

Individuals will be excluded if

• Not a parent or guardian of a child aged 2-12 years
• Younger than 20 years
• Not primarily responsible for more than half of the household grocery shopping
• Unable to read or understand Portuguese
• Do not provide informed consent.
