Here’s what you need to know about the debate over whole milk in school meals: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.Associated Press writers Paul Weber in Austin, Texas, Devi Shastri in Milwaukee and Margery Beck in Omaha contributed to this report.

is growing and thriving after getting an experimentalResearchers described the case in a new study, saying he’s among the first to be successfully treated with a custom therapy that seeks to fix a tiny but critical error in his genetic code that kills half of affected infants. Though it may be a while before similar personalized treatments are available for others, doctors hope the technology can someday help the millions left behind even as genetic medicine has advanced because their conditions are so rare.

“This is the first step towards the use of gene editing therapies to treat a wide variety of rare genetic disorders for which there are currently no definitive medical treatments,” said Dr. Kiran Musunuru, a University of Pennsylvania gene editing expert who co-authored the study published Thursday in the New England Journal of Medicine.The baby, KJ Muldoon of Clifton Heights, Pennsylvania, is one of 350 million people worldwide with rare diseases, most of which are genetic. He was diagnosed shortly after birth with severe CPS1 deficiency, estimated by some experts to affect around one in a million babies. Those infants lack an enzyme needed to help remove ammonia from the body, so it can build up in their blood and become toxic. A liver transplant is an option for some.
