WASHINGTON (AP) — A House committee has endorsed a Republican plan to allow some schools to opt out of healthier meal standards.

The vote comes as first lady Michelle Obama campaigns in support of the standards.

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. They say the rules have proved to be costly and restrictive.

The House Appropriations Committee voted to allow schools to opt out of the standards for the next school year if the schools are losing money on meal programs for six months.
