The Trump administration has finalized a rollback of school lunch regulations championed for years by former first lady Michelle Obama.

Under the rules first announced last year, schools are now allowed to offer more flavored milk options, like chocolate. Additionally, the Obama-era efforts to limit sodium content in school lunches have been delayed or partially eliminated. The announcement Thursday doesn't require schools to make any changes, but allows them to relax restrictions on those products.

The changes will impact 99,000 schools and institutions that feed 30 million children every year, according to the Department of Agriculture.

At a May 2017 press conference first announcing the move to deregulate school food, Agriculture Secretary Sonny Perdue said the decision was not meant to reduce nutritional standards. He argued that children would avoid nutritious foods all together if they weren't given more flavored options.

"I wouldn't be as big as I am today without chocolate milk," Perdue said at the time.

The decision is part of the Trump administration’s broad efforts to reduce “unnecessary regulatory burdens” across the federal government.

The Center for Science in the Public Interest, a food policy advocacy group, condemned the move.
