Project Modifying Eating and Lifestyles at School (MEALS) was a school-based study developed by the nonprofit organization Project Bread (www.ProjectBread.org) and the Harvard School of Public Health. Project Bread hired a professional chef to work with several schools in a low-income, urban school district in Massachusetts to enhance the palatability and nutrient profile of the school meals. Four schools were randomly assigned to receive the professional chef. Additionally, two schools in that district and four schools in a second school district were randomly assigned to receive a behavioral psychology intervention to influence the selection and consumption of the healthier foods offered. Selection and consumption were assessed at baseline, up to 3 months post-implementation (short-term implementation for chef-enhanced meals), up to 4 months post-implementation (long-term implementation for behavioral psychology) and/or up to 7 months post-implementation (long-term implementation for chef-enhanced meals).~Primary Aim 1: to examine the impact of introducing healthier, chef-enhanced foods with increased palatability on selection and consumption among elementary and middle school students. It is hypothesized that there will be an increase in the selection and consumption of entrees, fruits, and vegetables in schools where healthier, chef-enhanced foods are served.~Aim 2: to examine the impact of physical modifications to the placement and displays of foods in the cafeteria on selection/consumption among elementary and middle school students. It is hypothesized that there will be an increase in selection and consumption of entrees, milk, fruits, and vegetables when modifications are made.
The purpose of this study is to examine the impact of introducing healthier, chef-enhanced foods and/or environmental modifications (choice architecture) on selection and consumption of school foods among elementary and middle school students.
