Adherence
Warning labels significantly lower the perceived healthfulness and recommended consumption frequency of products high in energy, saturated fat, sugar, and sodium compared to GDA and traffic-light systems.
If you see a black warning label on a product, understand that it is a strong signal that the product is unhealthy. These labels are designed to make you think twice about how often you should eat it. Use this perception to limit your consumption of such items.

Products with high energy, saturated fat, sugar and/or sodium content that featured warnings on the label were perceived as less healthful than those featuring the GDA or traffic-light system.
Why this rating
