Changes could be coming to school lunches under President Donald Trump’s administration, but the Los Angeles Unified School District said it will keep serving healthy meals to students.

On Monday, Agriculture Secretary Sonny Perdue announced changes to federal nutrition standards, partially rolling back rules championed by former First Lady Michelle Obama as part of her healthy eating initiative. Schools won’t have to cut more salt from meals just yet, and some will be able to serve kids fewer whole grains, under the changes Perdue unveiled at a visit to Catoctin Elementary School in Leesburg, Va.

Also, an upcoming requirement to lower sodium levels in meals will be delayed, and waivers will still be allowed for the requirement that all grains on the lunch line must be 50 percent whole grain. Schools could also serve flavored 1 percent fat milk instead of the nonfat now required.

But in Los Angeles, Joseph Vaughn, director of Food Services Division for the district, said LAUSD will stick with healthy meals for its students.

“Nourishing children to achieve excellence is our core mission,” Vaughn said in a statement when asked for a response to Perdue’s comments, in reference to the division’s healthy food-focused goal. “We will continue to direct all efforts toward serving healthy meal options, providing nutrition education to families, and upholding nutrition standards that meet or exceed federal regulations.”

The district, which has about 664,000 students and, excluding adult students, has made big changes in its meal programs in the name of healthier food. Under its Good Food procurement policy, it moved last year to antibiotic-free and hormone-free chicken products in school meals. The board will soon consider a pilot program to introduce vegan options for school food. Vegetarian meals are already available.

The Obama administration rules set fat, sugar and sodium limits on foods in the lunch line and beyond. Schools have long been required to follow government nutrition rules if they accept federal reimbursements for free and reduced-price meals for low-income students, but these standards were stricter. Michelle Obama pushed the changes as part of her “Let’s Move” campaign to combat childhood obesity.

The Trump administration changes leave most of the Obama administration rules in place, including rules that students must take fruits and vegetables on the lunch line. Some schools have asked for changes to that policy, saying students often throw them away.

Health advocates who have supported the rules are concerned about the freeze in sodium levels, in particular. School lunches for elementary school students are now required to have less than 1,230 mg of sodium, a change put in place in 2014. The changes would keep the meals at that level, delaying until at least 2020 a requirement to lower sodium to 935 mg. That requirement was scheduled to begin in the 2017-2018 school year.

But students across the country, including in Los Angeles, rebelled against the healthier meals advocated by Michelle Obama, choosing chips over vegetables.

Perdue echoed that sentiment in his remarks Monday in Virginia, saying he doesn’t see the changes he announced as a rollback, but “we’re just slowing down the process.” He praised Obama’s nutrition efforts as first lady but said he wants the healthier meals to be more palatable.

“If kids aren’t eating the food, and it’s ending up in the trash, they aren’t getting any nutrition — thus undermining the intent of the program.”
