Jan. 9—What if eating healthy was as easy as playing your favorite childhood game?
In March 2010, Massachusetts General Hospital's cafeteria got an overhaul. Healthy items were labeled with a "green light," less healthy items were labeled with a "yellow light," and unhealthy items were labeled with a "red light." Healthier items were also placed in prime locations throughout the cafeteria, while unhealthy items were pushed below eye level.
The "Green Light, Red Light, Eat Right" method is a favorite among experts fighting childhood obesity. But doctors at Massachusetts General wanted to know if the colors could really inspire healthier eating habits among adults long-term.
