EL PASO — Not too many years ago, students eagerly awaited the bell that signals lunchtime, anticipating french fries, a can of Pepsi, and a chocolate chip cookie. Now, however, those same students have been challenged to abandon some of the junk foods they crave. In 2007, revisions were made to the Texas Public School Nutrition Policy to create a weapon to battle obesity in children. Texas public high schools have had to start abiding by laws that mandate healthier lunch foods, as well as changing vending machine products on their campuses. “Our snack bars are all run by the district cafeterias and have to abide by the changes in the law,” says Dr. Carla Gonzales, Chapin High School Principal.
