Adherence
Front-of-package labeling systems, particularly those with clear criteria like the Multiple Traffic Light or Choices logo, can drive industry product reformulation, leading to reduced sodium, saturated fat, and added sugar in processed foods.
Support labeling systems that require manufacturers to meet specific nutrient criteria (like low sodium or sugar limits) to display a favorable label. This forces companies to improve the actual nutritional content of their products, benefiting everyone, not just those who read labels.
GoodSupportsHIGH confidence
It is possible to argue that even a system that produces little impact on consumer behaviour could have considerable public health benefit if companies feel compelled to reformulate their foods.
Why this rating
Supported by specific case studies of the Choices program in the Netherlands and trans-fat labeling in the US, showing measurable reductions in target nutrients.

More from this paper
- The Multiple Traffic Light (MTL) front-of-package labeling system is the most effective existing labeling format for helping consumers correctly identify healthier food products compared to other systems like %Daily Intake or monochrome labels.Good
- Front-of-package labels that include interpretive text (e.g., 'High', 'Medium', 'Low') significantly improve label comprehension and correct nutrient identification compared to labels using only percentages or colors alone.Good
