A big change for school lunch.
Nationwide, schools are cutting the fat and sodium, serving only balanced, nutritious food to students.
One-third of kids in the U.S. are obese.
But now ninety percent of public schools took steps to change that.
It's a federal law.
the Healthy Hunger-Free Kids Act means the USDA will be checking up on school districts.
Some say this federal law steps on personal freedoms, but officials say there's no ban on junk food.
Kids can bring their own meals, they just can't share with their classmates.
And though the vending machines are turned off during school hours, if a student was in need of water or dealing with issues like low blood sugar, they can go to the school nurse at any time.
