ShareThis

In this factsheet, we review relevant, scientific literature on nutrient warnings for a science and policy audience. Overall, evidence from randomized controlled trials and real-world studies suggests that nutrient warnings can increase consumers’ understanding of the healthfulness of foods and have the potential to play a role in reducing purchases of foods and drinks high in calories, sodium, and added sugars. To maximize public health impact, policymakers should design nutrient warnings to be simple, highly visible, and convey information with shapes, icons, and other imagery in addition to text.
