Adherence
Warning labels and traffic-light systems are equally effective in helping consumers identify the most healthful product among a set of options, outperforming the GDA system.
When comparing products, look for warning labels or traffic-light systems. Both help you quickly spot the healthiest option, whereas GDA labels (numbers/percentages) are harder to use for comparison. Choose the product with the fewest warnings or the most green lights.
Warnings and the traffic-light system performed equally well in the identification of the most healthful product.
Why this rating
Statistically significant difference between directive/semi-directive vs non-directive, with no significant difference between the two directive types.

More from this paper
- Directive front-of-pack warning labels (e.g., Chilean stop-sign style) significantly improve consumers' ability to quickly identify products with high levels of key nutrients (sodium, sugar, saturated fat, energy) compared to non-directive (GDA) and semi-directive (traffic-light) systems.Good
- 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.Good
