WASHINGTON — A House committee has endorsed a Republican plan to allow some schools to opt out of more healthful meal standards.
The vote comes as Michelle Obama campaigns in support of the standards. On Tuesday, she met with school nutrition officials who said the guidelines are working in their schools.
The rules set by Congress and the Obama administration over the past several years require more fruits, vegetables, and whole grains in the lunch line. Also, there are limits on sodium, sugar, and fat.
Some school nutrition directors have lobbied for a break, saying the rules have proved to be costly and restrictive.
The Republican provision in an agriculture bill would allow schools to opt out of the standards if they are losing money on meal programs for a six-month period. The House Appropriations Committee rejected, by a 29-22 vote, a Democratic amendment that would have removed the GOP language. A subcommittee backed the spending bill last week.
Republicans have said the standards are overreach.
‘‘Bottom line is schools are finding the regulations to be too much too quick,’’ said Representative Robert Aderholt, Republican of Alabama, who wrote the language.
Democrats said they were concerned the provision was an attempt to permanently roll back the standards.
‘‘We don’t tell kids, you don’t have to take math if it’s hard, science if it’s hard,’’ said California Representative Sam Farr, who offered the amendment to strike the provision.
White House spokesman Jay Carney said the House language ‘‘replaces the judgment of doctors and nutritionists with the opinions of politicians regarding what is healthy for our kids.’’
The schools pushing for changes say limits on sodium and requirements for more whole grains are particularly challenging, while some officials say kids are throwing away required fruits and vegetables.
The Senate did not include the opt-out language in its version of the spending bill.
