Don’t touch my brownies!

More children would eat lunches and dinners at school under legislation passed Thursday by the House and sent to the president, part of first lady Michelle Obama’s campaign to end childhood hunger and fight childhood obesity.

A child nutrition bill on its way to President Barack Obama — and championed by the first lady — gives the government power to limit school bake sales and other fundraisers that health advocates say sometimes replace wholesome meals in the lunchroom.

Republicans, notably Sarah Palin, and public school organizations decry the bill as an unnecessary intrusion on a common practice often used to raise money.

“This could be a real train wreck for school districts,” Lucy Gettman of the National School Boards Association said Friday, a day after the House cleared the bill. “The federal government should not be in the business of regulating this kind of activity at the local level.”

The legislation, part of first lady Michelle Obama’s campaign to stem childhood obesity, provides more meals at school for needy kids, including dinner, and directs the Agriculture Department to write guidelines to make those meals healthier. The legislation would apply to all foods sold in schools during regular class hours, including in the cafeteria line, vending machines and at fundraisers.

It wouldn’t apply to after-hours events or concession stands at sports events.

Public health groups pushed for the language on fundraisers, which encourages the secretary of Agriculture to allow them only if they are infrequent. The language is broad enough that a president’s administration could even ban bake sales, but Secretary Tom Vilsack signaled in a letter to House Education and Labor Committee Chairman George Miller, D-Calif., this week that he does not intend to do that. The USDA has a year to write rules that decide how frequent is infrequent.

Margo Wootan of the Center for Science in the Public Interest says the bill is aimed at curbing daily or weekly bake sales or pizza fundraisers that become a regular part of kids’ lunchtime routines. She says selling junk food can easily be substituted with nonfood fundraisers.

“These fundraisers are happening all the time,” Wootan said. “It’s a pizza sale one day, doughnuts the next… It’s endless. This is really about supporting parental choice. Most parents don’t want their kids to use their lunch money to buy junk food. They expect they’ll use their lunch money to buy a balanced school meal.”

Not all see it that way.

Some parents say they are perplexed by what the new rules might allow.

In Seminole, Fla., the Seminole High Warhawks Marching Band’s booster club held a bake sale to help send the band’s 173 members to this year’s Macy’s Thanksgiving Day parade in New York. One of the bake sale’s specialties: New York-style cheesecake, an homage to the destination they’d pursued for 10 years.

“Limiting bake sales is so narrow-minded,” said Laura Shortway, whose 17-year-old daughter, Mallory, is a drummer in the band. “Having bake sales keeps these fundraisers community based, which is very appealing to the person making the purchase.”
