Adherence
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.
When choosing between products, look for packages with black warning labels (like the Chilean system). These labels are designed to grab your attention faster than traffic lights or numbers, helping you quickly spot items high in sugar, salt, or fat. Use this visual cue to avoid products with high levels of these nutrients.
Warnings improved consumers’ ability to correctly identify a product with high content of a key nutrient within a set of labels compared with GDA and received the highest goal-directed attention.
Why this rating
Controlled experimental studies with clear statistical significance (P < 0.001) on reaction times and accuracy.

- 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
- 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.Good
