After conducting focus groups to test and determine the most effect shape, color, and style for the proposed warning labels, the research team in South Africa conducted a randomized controlled trial to test the warning label alongside a traffic light label and Guideline Daily Amounts label. This experiment was led by Rina Stewart as part of a Department of Health task force. UWC compiled an extensive technical report that summarized all of their research on nutrient profiling models and front-of-package labels, which they presented to the National Department of Health with their evidence-based policy recommendations. This report is currently not available to the public. The draft front-of-package warning label regulation is now in the Department of Health’s hands.
