Schools are an important setting for addressing childhood obesity. A substantial portion of school-aged children’s daily food and caloric intake occurs within the school and after-school environment. About 30 million school-aged children consume school lunches every day, and almost 75% (21.8 million) of these children receive free or reduced-price lunches.
