“You have undermined the vital role vaccines play in preventing disease during the single, largest measles outbreak in 25 years,” Democratic Sen. Bernie Sanders said.

In 2010, Congress passed the Healthy, Hunger-Free Kids Act, which aimed to reduce childhood obesity and cut health risks for kids. It required school meals to include more whole grains, fruits and vegetables, protein and low-fat dairy and less sugar, sodium and fat.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.It’s “very exciting” that the team created the therapy so quickly, said gene therapy researcher Senthil Bhoopalan at St. Jude Children’s Research Hospital in Memphis, who wasn’t involved in the study. “This really sets the pace and the benchmark for such approaches.”

In February, KJ got his first IV infusion with the gene editing therapy, delivered through tiny fatty droplets called lipid nanoparticles that are taken up by liver cells.While the room was abuzz with excitement that day, “he slept through the entire thing,” recalled study author Dr. Rebecca Ahrens-Nicklas, a gene therapy expert at CHOP.

After follow-up doses in March and April, KJ has been able to eat more normally and has recovered well from illnesses like colds, which can strain the body and exacerbate symptoms of CPS1. The 9 ½-month old also takes less medication.Considering his poor prognosis earlier, “any time we see even the smallest milestone that he’s meeting – like a little wave or rolling over – that’s a big moment for us,” his mother said.
