Snack foods sold in schools are getting their first nutritional overhaul in more than 30 years.
New federal rules released Thursday are setting limits for fat, salt, and sugar in school snacks.
Under so-called "Smart Snacks in School" standards, snacks must be limited to 200 calories, while increasing protein, whole grains and nutrients.
Sodas and sports drinks sold in high schools must contain 60 calories or less in a 12-ounce serving.
Special fundraising events, such as bake sales, will still be allowed.
The rules, which should be in effect for the 2014-2015 school year, are meant to help curb childhood obesity in the U.S.
