Whole milk is back in schools. Is that a good thing?

The return of whole milk to school lunches is a relatively good thing, but what matters more is a child’s overall diet and attitudes toward food they get at home, according to Brittany Grigorenko, a clinical inpatient dietitian at Cape Cod Hospital in Hyannis.

“I’d rather a cup of milk at school than a candy bar or juice,” she said. “Fat (in whole milk) will get them a little more full,” and not as likely to turn to a less nutritious snack.

On Jan. 14, 2026, President Donald Trump signed the Whole Milk for Healthy Kids Act that restored whole milk as an option to be served with school lunches, announced the U.S. Department of Agriculture. It joins a revision of child nutrition programs planned to align them with new federal dietary guidelines that recommend three servings a day of full-fat dairy products with no added sugar.

Whole milk and 2 percent milk were eliminated from school lunches by a 2012 act requiring only fat-free and low-fat milk to be offered. Then First Lady Michelle Obama touted the move as a part of a bigger push to reduce obesity among children, according to a Reuters news story. In his first term, President Trump also changed another Obama-era rule and permitted flavored milk to be served in schools.

Whole Milk and Healthy Habits

The change “sounds great” if it encourages children to drink more milk, said Grigorenko, who is also a cardiac rehabilitation dietitian. Children who drink whole milk at home may be less inclined to drink low-fat or fat-free milk in school. And milk is a good way to provide the calcium and vitamin D they need.

“Calcium is good for bones and teeth. If they don’t get enough in, they can’t get it in later, when bones are developed,” she said.

The only significant difference between whole milk and lower-fat or no-fat milk is fat content and calorie count. Here’s a comparison from U.S. Dairy for a cup of each:

• Whole milk – 152 calories and 8 grams of fat, of which 5 grams are saturated fat.
• Reduced fat or 2 percent milk – 122 calories and 5 grams of fat, of which 3 grams are saturated fat.
• Low-fat or 1 percent milk – 106 calories and 2 grams of fat, of which 1 gram is saturated fat.
• Fat-free milk – 84 calories and 0 grams of fat, so no saturated fat.

The industry group notes most milk is fortified with vitamin D and lower-fat and fat-free milk is fortified with vitamin A because some of this nutrient is lost when fat is removed.

A Dietitian’s Advice

Milk forms an essential part of children’s diets, starting at birth. Infants can stay on breast milk until about 1 year old, Grigorenko said. At that point, they can switch to whole milk. By their second birthday, children can switch off whole milk, if that’s what parents want, but it should be replaced by lower-fat or fat-free milk or plant milks fortified with calcium and vitamin D, which helps with absorption of calcium.

“I’m a parent myself, and have whole milk at home for my toddler,” she said.

Our bodies need exposure to sunshine to make vitamin D, and people living in northern climes may not get enough sun, so supplementation helps ensure children get the vitamin D they need. Calcium may also be obtained from some other foods, such as spinach, collard greens, kale, bok choy, canned sardines or salmon, tofu, tahini, almonds and fortified orange or grapefruit, according to the USDA.

For decades, consuming too much saturated fat has been linked to raising blood cholesterol levels and risk of heart disease, according to the American Heart Association. It suggests saturated fats should be kept to no more than 6 percent of daily calories for someone who eats 2,000 calories a day, or about 13 grams of saturated fat. These fats are found in dairy products, meat, coconut, and palm and palm kernel oils.

But science’s view of the link between saturated fats and heart disease is changing. A Feb. 1, 2023, article in Current Opinion in Endocrinology, Diabetes and Obesity said the quality of the research that postulated the link to heart disease has been questioned, and the link is not a proven fact but a weak association.

While whole milk contains saturated fat, Grigorenko said a cup at lunchtime forms only a small part of a child’s daily diet. A child’s entire diet, and their individual health, should be considered. Are they overweight, or have a family history of high cholesterol? Is school lunch the one solid meal they get most days?

“I’d rather have them eat something than nothing at all,” she said, adding that children who go home hungry may fill up on fast and less nutritious foods, such as cereal or chips.

Grigorenko also cautioned about attaching negative comments to certain foods, such as whole milk, as they could backfire.

“Kids pick up on that and that’s where eating disorders can stem from,” she said.
