AUSTIN, TX - MARCH 11: Students line up to receive food during lunch in the cafeteria at Bowie High School March 11, 2004 in Austin, Texas. The Austin School District is working to make their cafeteria offerings more healthy, but the most popular foods are still fried chicken strips, pizza, and french fries. Concern about increased levels of childhood obesity in the United States has made the food served in public schools cafeterias a much greater concern. (Photo by Jana Birchum/Getty Images)
