Penn State researchers do not believe that serving junk food in schools causes weight gain in children.

Their new study found junk food sales don't make much of a difference in the weight of middle school students.

Researchers even found that students who moved into schools that offered access to junk food actually lost weight over time.

Obesity experts said that as of preschool, it is necessary for children to see a consistent message about healthy eating.
