Traffic Light Foods Labels: Helping Consumer Make Better Choices

Researchers at the University of Bonn have reached the conclusion that the traffic light label is more effective in helping consumers resist high-calorie foods than a purely information-based label.


Red, yellow, green: The traffic signal labels on packages are supposed to be an easy-to-understand indication of the overall “healthiness” of a food product. For example, “red” symbolizes a high percentage of fat, sugar or salt, “green” a lower percentage. Just as on an actual traffic light, yellow falls in the middle.

The traffic light label appears to enable the study participants to better resist unhealthy foods compared to a label containing the traditional information on grams and percentages of the particular ingredients. A traffic light label probably implicitly increases the weight consumers place on healthiness in their decision.

The use of traffic light labelling is supported by many physician groups including the British Medical Association and welcomed by consumers. Despite worries from some in the food industry that red foods would be shunned, the British Medical Association, Food Standards Agency and others agree that consumers interpret the labels sensibly, realize they can have red foods as a ‘treat’, and they are easier to understand than lists of percentages.

The new traffic light food labelling system to help consumers know how much fat, sugar, salt and energy a food product contains risks interpretation that there is something to hide.
