That being that kids are fat because they can get junk food at school, there for junk food should be banned from school. Sounds nice, but they are wrong, this loss of liberty is for no gain.
The study followed 19,450 fifth graders of both sexes for four years. At the beginning, 59 percent of the students went to schools that sold “competitive foods”—that is, non-cafeteria fare not reimbursable through federal meal programs. CFs tend to have higher sugar or fat content and lower nutritional value (think the indulgences at the top of the food pyramid, like Coke and Oreos). By the time the students reached eighth grade, 86 percent of them attended schools that sold competitive foods. The researchers, led by Pennsylvania State University’s Jennifer Van Hook, then compared body mass indexes from the 19,450 students, including those who’d spent all four years in junk food-free environments, those who’d left such schools for vending machine-friendly ones, those who’d transferred from vending machine-friendly schools to junk food-free schools, and those who enjoyed access to vending machines for all four years. Regardless of which data sets they contrasted, the researchers were unable to find any sort of connection between obesity and the availability of “unhealthy” snacks in school. In other words, children who could theoretically grab a Snickers bar after class every day for four years were, on average, no heavier than those who couldn’t.
