WASHINGTON — Kids, your days of blowing off those healthier school lunches and filling up on cookies from the vending machine are numbered. The government is onto you.

What they said

Local school superintendents were asked about the new school food standards:

Nancy McGinley, Charleston County School District:

The school district has been proactive during the past few years in trying to reduce calories and high-fat food items in its cafeterias, and these new rules strengthen the district's position and help its effort to combat childhood obesity, McGinley said.

If anything, she said, the district already has made some of these changes and it's ahead of the game.

“I know change is always met with some resistance, but ultimately, it's in the best interest of kids,” she said.

Joe Pye, Dorchester District 2:

Pye said it will be an adjustment at first but that he hopes parents will follow suit.

“We're trying to teach the children good, healthy habits early on before they develop these phobias, 'I can't eat spinach.' I wouldn't eat any of that stuff as a child and I'm telling you, I crave spinach today.”

Pye said he thinks the rules are well-intended and will be criticized. “But if you're hungry enough and you eat it, you'll find out it really wasn't so bad after all.”

Rodney Thompson, Berkeley County School District, was unavailable for comment.

For the first time, the Agriculture Department is telling schools what sorts of snacks they can sell. The new restrictions announced Thursday fill a gap in nutrition rules that allowed many students to load up on fat, sugar and salt despite the existing guidelines for healthy meals.

“Parents will no longer have to worry that their kids are using their lunch money to buy junk food and junk drinks at school,” said Margo Wootan, a nutrition lobbyist for the Center for Science in the Public Interest who pushed for the new rules.

That doesn't mean schools will be limited to doling out broccoli and brussels sprouts.

Snacks that still make the grade include granola bars, low-fat tortilla chips, fruit cups and 100 percent fruit juice. And high school students can buy diet versions of soda, sports drinks and iced tea.

But say goodbye to some beloved school standbys, such as doughy pretzels, chocolate chip cookies and those little ice cream cups with their own spoons. Some may survive in low-fat or whole wheat versions. The idea is to weed out junk food and replace it with something with nutritional merit.

The bottom line, says Wootan: “There has to be some food in the food.”

Still, 17-year-old Vanessa Herrera is partial to Cheez-It crackers and sugar-laden Vitaminwater. Granola bars and bags of peanuts? Not so much.

There are no vending machines at Lauren Jones' middle school in Hoover, Ala., but she said there's an “a la carte” stand that sells chips, ice cream and other snacks. “Having something sweet to go with your meal is good sometimes,” the 13-year-old said, although she also thinks that encouraging kids to eat healthier is worthwhile.

The federal snack rules don't take effect until the 2014-15 school year, but there's nothing to stop schools from making changes earlier.

Many schools already are working to improve their offerings. Thirty-nine states have some sort of snack food policy in place.

The federal rules put calorie, fat, sugar and sodium limits on almost everything sold during the day at 100,000 schools — expanding on the previous rules for meals. One oasis of sweetness and fat will remain: Anything students bring from home, from bagged lunches to birthday cupcakes, is exempt from the rules.
