Nudging for Behavior Change in School Cafeterias

"The intervention consists of three components: 1) serving fresh fruit in attractive bowls in at least two locations on the lunch line; 2) providing descriptive names for the vegetables; and 3) increasing amount of plain milk availability by 10% and placing it in front of the chocolate milk. For the vegetable naming intervention, researchers first developed, printed, and laminated descriptive vegetable name cards (2x4). Some examples included Savory Collard Greens, and \[School Mascot\] Salad. Cafeteria staff affixed name cards to the serving line sneeze-guards in front of the vegetables for the day. For the fruit intervention, we purchased and delivered two ceramic bowls to the intervention school. The cafeteria staff filled the bowls and put them in different locations on the lunch line. For the milk intervention, cafeteria staff increased the amount of plain milk available by 10% and placed plain in front of chocolate milk in the coolers."
