A group of researchers examined whether children's food selection in a school cafeteria met the standards set by the School Meals Initiative. They measured food selection and food intake of 2049 fourth- through sixthgrade students in 33 schools over a three-day period using digital photog- raphy. The following table summarizes some of the food intake measurements. Boys Girls n = 852 n = 1197 Food intake Mean St. Mean St. Dev. Dev.
