Simple 'traffic light' nutrition labels significantly influence fast-food purchasing decisions, even more than price or brand. This innovation & markets research insight is drawn from a 2016 study published in British Food Journal. Using Discrete choice experiment with conjoint analysis with 248 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Implement 'traffic light' style nutrition labelling on fast-food products to maximize impact on consumer purchasing decisions.
Traffic Light Nutrition Labels Outperform Price and Brand in Fast Food Choices
Simple 'traffic light' nutrition labels significantly influence fast-food purchasing decisions, even more than price or brand.
British Food Journal · 2016
Key Findings
- 01The 'traffic light signal' method was the most influential, accounting for 41% of the importance in consumer decision-making.
- 02The 'traffic light signal' outperformed product pricing and branding in influencing choices.
- 03More information-laden methods like 'guided daily amounts' (27%) and 'health endorsement' (13%) were less effective than the traffic light system.
Application
Design takeaway
Implement 'traffic light' style nutrition labelling on fast-food products to maximize impact on consumer purchasing decisions.
How to apply
When designing packaging or menu information for fast-food items, utilize a 'traffic light' colour-coding system (e.g., green for healthy, yellow for moderate, red for unhealthy) to clearly communicate nutritional value.
Project actions
- 01When researching consumer preferences, consider using visual aids like different labelling systems.
- 02Think about how to measure the 'importance' of different factors in a consumer's decision.
- 03Control for variables like price and brand when testing the impact of your design feature.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Uses a robust experimental design (discrete choice experiment).
- +Controls for key confounding variables like price and brand.
- +Provides quantitative data on the relative importance of different labelling methods.
Limitations
The study was conducted in a specific market (fast food) and may not apply to other food sectors. The participants' actual purchasing behaviour might differ from their stated preferences in an experiment.
Reliability & validity
The use of a discrete choice experiment with a sufficiently large sample size enhances the reliability of the findings. The control of variables like price and brand strengthens the internal validity by isolating the effect of the labelling methods.
Think critically
To what extent can 'traffic light' systems be universally applied across different food types and cultural contexts, and what are the ethical considerations of using such systems to influence consumer behaviour?
Design Principles
"Simplicity in information design enhances user comprehension and decision-making."
This research highlights the power of clear, concise nutritional information in guiding consumer behaviour within the fast-food industry. Designers and marketers can leverage this insight to develop more effective product labelling strategies that genuinely impact consumer choices and promote healthier eating habits.
What This Means for Your Design
A simple red, yellow, and green system for showing if fast food is healthy is the best way to help people choose what to buy, even better than making it cheaper or using a famous brand name.
How to use in your project
- 1.This study can inform the design of nutritional information for food products, demonstrating the effectiveness of simple visual cues.
- 2.The methodology, such as discrete choice experiments, can be adapted to test other design features and their impact on consumer behaviour.

Paragraph starter
Research indicates that simple visual cues, such as 'traffic light' nutrition labelling, can be highly effective in influencing consumer choices within the fast-food sector, often surpassing the impact of price or brand recognition. This suggests that clear, easily digestible information design is a critical factor in guiding purchasing decisions and promoting healthier eating habits.
