When schools aren’t forced to provide healthy food, they usually don’t, according to a new study published in JAMA Pediatrics.

But for the small percentage of kids who did attend schools that revamped nutrition, researchers saw positive trends for obesity rates, suggesting wider execution really could lead to better health for students.
Researchers looked at nationally representative data of 22,716 eighth-grade students in 313 schools and 30,596 10th and 12th grade students in 511 schools from the 2007-2008 through 2011-2012 school years. That time span was before the new federal standards for school lunches were required to be implemented, though schools were well aware of them and knew when their deadlines were. “We were surprised by the number of students who attended schools where none of the noted standards were in place,” says study author Dr. Yvonne M. Terry-McElrath of the University of Michigan. “Full implementation of the standards will significantly improve U.S. school nutrition environments.”
