U.S. First Lady Michelle Obama is fighting a Republican effort requesting to amend some important part of her school lunch program after some districts complained about losing money.

 The First Lady vowed to "fight until the bitter end" to protect her initiative-- Healthy Hunger-Free Kids Act of 2010. This program aims to improve child nutrition by making real reforms to the school lunch and breakfast programs. In 2010, her husband signed the bill reauthorizing the funding of the program in schools for five years with a budget of $4.5 billion. But in 2011, the government spending reached $10.1 billion.

Since then, the Republicans consistently criticized the School Lunch program and filed an agriculture spending bill that would allow schools to waive the standards if they were losing money with six months. Alabama representative Robert Adelhort, author of the bill, explained that the requests came from school food directors.

"Our request for flexibility under the new standards does not come from industry or politics, it comes from thousands of school cafeteria professionals who have shown how these overly prescriptive regulations are hindering their effort to get students to eat healthy school meals," said Leah Schmidt, president of the School Nutrition Association (NSA), to TIME.

Obama argued that money loss should not be a reason to downgrade the nutrition standards of the school lunch program which requires more fruit, vegetables, and whole grains in each meal, as well as reducing sodium, sugar, and fat.

NSA spokeswoman Diane Pratt-Heavner explained that the school lunch program is no longer that effective as more than 1 million children eat lunch at school each day since 2012.

"How can we call these standards a success when they are driving students away from the program?" she told the Associated Press. 

Meanwhile, the First Lady remained firm on her stand that the proposal was unacceptable and even accused the Republicans playing politics regarding the issue.

"The last thing that we can afford to do right now is play politics with our kids' health, especially when we're finally starting to see some progress on this issue," the First Lady spoke before a group of nutrition experts in a meeting held in the White House, quoted by AP.
