Hoping to combat the growing epidemic of childhood obesity, the Obama administration on Wednesday announced its long-awaited changes to government-subsidized school meals, a final round of rules that adds more fruits and green vegetables to breakfasts and lunches and reduces the amount of salt and fat.

The announcement came months after the food industry won a vote in Congress to block the administration from carrying out an earlier proposal that would have reduced starchy foods like potatoes and prohibited schools from counting a small amount of tomato paste on a slice of pizza as a vegetable. Under the latest rules, potatoes are not restricted, and tomato paste can qualify as a vegetable serving.

The rules were announced by Agriculture Secretary Tom Vilsack and Michelle Obama at Parklawn Elementary School, in Alexandria, Va.
