A nutrition study investigated knowledge about fruit juices. The study was conducted in a pediatric clinic. An initial study identified a lack of knowledge about the nutritional value of fruit drinks, and the participating parents were randomly assigned to an educational program (intervention, =75n=75) or given a short informational brochure (control, =75n=75). At the end of the program, they were asked to rate the juice content of a national brand of fruit drink that contained about 5%5% juice.
