From the 9 March 2015 AlphaGalileo news release

Should food products be labeled with traffic light symbols to make health-related information on ingredients easier to understand? This question has remained a subject of debate. Now 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. Scientists observed study participants in the brain scanner as they made purchase decisions. The study has just been published in the journal Obesity.

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. ” This is the first study that analyzes the effect that traffic light signals have on the evaluation processes in the consumer’s brain when making a purchase decision”, says Prof. Dr. Bernd Weber of the Center for Economics and Neuroscience (CENs) at the University of Bonn. Do the “traffic lights” help consumers choose a healthier diet when grocery shopping? Scientists from the CENs have addressed this question in a recent study.
