The U.S. Department of Agriculture recently proposed new standards for snack (competitive) foods in schools, similar to the Competitive Foods Guidelines developed by the Alliance for a Healthier Generation. This project will objectively track changes in snack food purchasing among K-12 public schools as a result ofthese standards. The aims of this work are to describe trends and establish a baseline for district-level purchases of snack foods by repurposing the lnterflex commercial bids database. This database provides public information on purchases made by over 500 K-12 school operators, which represents more than 46 percent of all food and supply bids put out by the schools. Analysis will include schools in the following districts: Little Rock/Pulaski, Ark.; Los Angeles Unified, Calif.; Milwaukee Public Schools, Wis.; Pittsburgh Public Schools, Pa.; Clark County, Nev.; Phoenix, Ariz.; and Dallas Independent School District, Texas.
