A new Republican-backed bill in the U.S. House of Representatives aims to scale back requirements imposed on school lunches, reports The Washington Post. This would allow some districts to opt out of federal mandates passed in 2010 to reduce sodium and increase whole grains, fresh fruits, and vegetables in school lunches. The food industry and some school officials have supported the Republican efforts.

First Lady Michelle Obama has been a champion of school nutrition improvement, including these new dietary standards, which were authorized by the Healthy Hunger-Free Kids Act of 2010. The White House contends that these measures have already demonstrated improvements in children’s health.

According to The Hill, the First Lady has made fighting childhood obesity her signature issue and launched the Let’s Move! initiative to combat it. If passed, these Republican efforts would erode new nutrition standards President Obama’s administration has set up. The First Lady is ready to take on an unprecedented level of involvement in politics, arguing that the GOP is “playing politics with our kids’ health.”

The School Nutrition Association, a supporter of Republican efforts, argues that schools are struggling to meet standards. Certification of successfully meeting standards only samples a small period of time, not taking into account the long-term struggle. Additionally, the School Nutrition Association contends that sodium limits have not been met by a single school. The School Nutrition Association emphasizes that they are looking for “reasonable flexibility” rather than an overhaul or elimination of standards.
