To help staff and visitors make healthy food choices, all foods in the cafeteria at Massachusetts General Hospital come with a colour-coded food label.
Red-labelled foods such as burgers are to be avoided, foods with yellow labels are meant to be eaten sparingly and green foods are healthy choices that should be chosen most often.
Researchers at the hospital have been collecting receipts for two years, and they noted a 20 per cent drop in consumption of red-labelled foods and a 15 per cent increase in green-label choices.
Dr. Anne Thorndike, who conducted the research, said, "It creates a visceral reaction when you see it. A red, yellow or green, we all know what it means. You don't need to speak English. It's pretty much a gut reaction."
