First Lady Michelle Obama sent a strong message to Republicans in Congress who want to allow local school districts to opt out of the federal regulations on school lunches.

“This is unacceptable,” she said during a roundtable discussion of the issue. “It’s unacceptable to me not just as First Lady but also as a mother.”

The strict rules, passed in 2010, limit the amount of fat, calories, sugar, and sodium served in school meals.

House Republicans are supporting a measure that would allow some school districts to opt out of the standards — if they can prove that it is affecting their school budgets.

The First Lady pointed out that since the regulations, kids in the United States were eating more fruits and vegetables.
