Summary
This study compared three front-of-pack nutrition labelling schemes—warnings, guideline daily amounts (GDA), and traffic-light systems—using visual search tasks and consumer surveys (n=387). Warnings demonstrated superior performance in directing consumer attention and enabling correct identification of products with high nutrient content compared to GDA labels, and were perceived as more effective at flagging unhealthful products than either GDA or traffic-light systems. Warnings and traffic-light systems performed equally for identifying the healthiest product option.
Regional applicability
The study's geographic location is not specified in the abstract; however, findings are relevant to United Kingdom food policy and consumer research, as front-of-pack labelling schemes remain a focus of UK regulatory discussions on tackling diet-related disease. The effectiveness of warning labels demonstrated here could inform UK regulatory decisions on mandatory FOP nutrition labelling design.
Key measures
Goal-directed attention (visual search task performance); perceived healthfulness (survey); ability to correctly identify products with high sodium/energy/saturated fat/sugar content; ability to identify the most healthful product alternative
Outcomes reported
The study compared three front-of-pack (FOP) labelling systems—warnings, guideline daily amounts (GDA), and traffic-light labels—in terms of consumer goal-directed attention, perceived healthfulness of products, and ability to identify products with high nutrient content. Participants completed a visual search task and survey to evaluate label effectiveness.
