  Purpose

This study builds on the framework of a previously implemented color-coded food labeling intervention in a hospital cafeteria by testing the incremental effectiveness of providing employees with individual feedback and incentives for increasing healthy purchases in a 3-arm randomized controlled trial. The investigators hypothesize that employees assigned to receive feedback will increase healthy purchases more than employees who receive no contact and that employees who receive feedback plus incentives will increase healthy purchases more than those who receive feedback alone.

Arms Assigned Interventions
Experimental: Feedback only
Subjects receive feedback letters about the proportion of green, yellow, and red purchases in the cafeteria per month with comparisons to "all employees" and to the "healthiest employees eaters"

Subjects receive feedback letters about the proportion of green, yellow, and red purchases in the cafeteria per month with comparisons to "all employees" and to the "healthiest employees eaters"
Experimental: Feedback plus incentives
Subjects receive feedback letters plus small incentives to increase healthy (green-labeled) purchases in the next month
Behavioral: Feedback plus incentives
Subjects receive feedback letters plus small incentives to increase healthy (green-labeled) purchases in the next month
No Intervention: Control group
