The nutrition knowledge, attitudes, and practices of secondary teachers of health and physical education, home economics, science, and social studies were assessed. Of the 518 teachers who completed the survey instruments, 43 percent had never taken a food or nutrition course, and 63 percent had no inservice training in nutrition or food instruction. Home economics teachers scored significantly higher than did other teachers on a test measuring nutrition knowledge level. In a measurement of attitudes toward teaching nutrition, home economics teachers were assessed as having the most positive attitudes, while social studies teachers had the least positive. The assessment of teachers' attitudes toward their own nutrition found no clear differences among the teachers, all of whom had positive attitudes toward their own nutrition. Nearly two-thirds of the teachers reported teaching some aspect of food and nutrition in their classes. Generally, teachers who taught about food and nutrition had taken more food and nutrition courses and had higher knowledge scores and more favorable attitudes toward teaching nutrition. The data support the idea that teachers should have preservice training in food and nutrition. (Authors/FG)
