Adherence

Interpretive front-of-pack (FOP) nutrition labels that evaluate product unhealthfulness (e.g., stop signs, traffic lights) are more effective at guiding consumers toward healthier choices than positive signposts or non-interpretive labels.

If you are a policymaker, prioritize interpretive labels (like stop signs or traffic lights) that highlight unhealthiness over positive endorsements or raw numbers. Ensure the regulation is mandatory, clearly defined, and developed with independent experts to withstand legal challenges from the food industry. This approach is more likely to help consumers, especially those with lower literacy, make healthier choices.
