An experimental "Traffic Light" food labeling system used in a large hospital cafeteria has helped boost healthy food purchases even two years after the experiment ended.
In 2010, foods at Massachusetts General Hospital were labeled green for healthy down to red for foods with little nutritional value.
Healthy items were displayed where they were most likely to be seen.
Immediately, employees and visitors started buying healthier foods.
Two years later, "green items" were still up 12 percent, and "red items" dropped 20 percent.
