School authorities in a total of 68 Alberta school jurisdictions (representing 82 percent of the student population of the province) responded to a request for details about the availability in schools of nonnutritious foods--defined as food that contains minimal nutrients in proportion to number of calories. Foods that are commonly consumed at school are categorized into four groups according to their dental and nutritional values. Information provided by respondents is summarized in this report. The key findings are that vending machines, the majority of which dispense pop and other nonnutritious items, are disallowed or strongly discouraged in the vast majority of elementary schools, but are present in about 40 percent of the junior high schools and 75 percent of the high schools. Described are the "Nutrition At School" programs sponsored by Alberta Agriculture that teach elementary school children the value of good nutrition. (MLF)
