['Nearly two million California children regularly spend time in child care. Surprisingly little is known about the nutrition environments of these settings. The aim of this study was to compare foods and beverages served to 2- to 5-year-olds by type of child care and participation in the federally funded Child and Adult Care Food Program (CACFP).', 'A statewide survey of child care providers (n = 429) was administered. Licensed child care was divided into six categories: Head Start centers, state preschools, centers that participate in CACFP, non-CACFP centers, homes that participate in CACFP, and non-CACFP homes.', 'CACFP sites in general, and Head Start centers in particular, served more fruits, vegetables, milk, and meat/meat alternatives, and fewer sweetened beverages and other sweets and snack-type items than non-CACFP sites. Reported barriers to providing nutritious foods included high food costs and lack of training.'] Is participation in the child and adult care food program associated with more nutritious foods and beverages in child care?
