Traffic light food labels, prominent positioning of healthy items produce lasting purchase choice changes

23 January 2014

The use of color-coded traffic light food labels and changes in the way popular items are displayed appear to have produced a long-term increase in the choice of more healthful food items among customers in a large hospital cafeteria.
A Massachusetts General Hospital (MGH) team reports that the previously reported changes in the proportions of more and less healthy foods purchased in the months after their program began have persisted up to two years after the labeling intervention was introduced. An article about the research is published in the American Journal of Preventive Medicine (News Release Massachusetts General Hospital, 7 January 2014).
