Knowing KJ’s odds, parents Kyle and Nicole Muldoon, both 34, worried they could lose him.

Starting in 2012, whole and 2% milk was not permitted in school meals because those products are higher in saturated fat and calories than lower-fat options.Nutrition experts said that skim and low-fat milk gave kids the benefits of necessary nutrients like calcium and Vitamin D with less fat and fewer calories.

The U.S. Agriculture Department sets nutrition guidelines for the national school lunch and breakfast programs, which serve nearly 30 million students each school day.The nutrition standards are required to meet the federal Dietary Guidelines for Americans, which are reviewed and revised every five years. Since 1985, those guidelines have recommended that Americans older than age 2 consume low-fat or fat-free dairy.The 2025-2030 dietary guidelines are set for revision this year under a joint effort by USDA and the Department of Health and Human Services. A panel of scientific experts who reviewed evidence regarding milk fat content recommended that the U.S. policy remain the same.

changes in the federal nutrition program after the 2010 law have slowed the rise in obesity among U.S. kids — even teenagers, said Deanna Hoelscher, a nutrition expert and researcher at the University of Texas Health Science Center who served on the dietary guidelines committee.“We didn’t find enough definitive evidence to change a policy that’s been in place that has shown good outcomes to date,” Hoelscher said.

Although there was limited evidence that consuming higher-fat dairy rather than lower-fat dairy could benefit very young children, there wasn’t enough evidence to make a conclusion for older kids and teens, she said. There were “substantial concerns” with the consistency, quantity and risk of bias in the existing research, the report concluded.

Some nutrition experts point toMusunuru said his team’s work —

— showed that creating a custom treatment doesn’t have to be prohibitively expensive. The cost was “not far off” from the $800,000-plus for an average liver transplant and related care, he said.“As we get better and better at making these therapies and shorten the time frame even more, economies of scale will kick in and I would expect the costs to come down,” Musunuru said.

Scientists also won’t have to redo all the initial work every time they create a customized therapy, Bhoopalan said, so this research “sets the stage” for treating other rare conditions.Carlos Moraes, a neurology professor at the University of Miami who wasn’t involved with the study, said research like this opens the door to more advances.
