The principal and teachers are happy about this. But some student are not. Dana Alvarez is a student at Fremont High School and she is angry. She say, I like to have soda and chips for lunch. It is not fair that i can not choose the food i like. But the principal and teachers at this large California school disagree with Dana. In the U.S 14 of teenagers are overweight. Doctors say that junk food is one reason for that problem.
