Whole milk is heading back to school cafeterias across the country after President Donald Trump signed a bill Wednesday overturning Obama-era limits on higher-fat milk options.

Nondairy drinks such as fortified soy milk may also be on the menu in the coming months following adoption of the Whole Milk for Healthy Kids Act, which cleared Congress in the fall.

The action allows schools participating in the National School Lunch Program to serve whole and 2% fat milk along with the skim and low-fat products required since 2012.

“Whether you’re a Democrat or a Republican, whole milk is a great thing,” Trump said at a White House signing ceremony that featured lawmakers, dairy farmers and their children.

The law also permits schools to serve nondairy milk that meets the nutritional standards of milk and requires schools to offer a nondairy milk alternative if kids provide a note from their parents, not just from doctors, saying they have a dietary restriction.

The signing comes days after the release of the 2025-2030 Dietary Guidelines for Americans, which emphasize consumption of full-fat dairy products as part of a healthy diet. Previous editions advised that consumers older than 2 should consume low-fat or fat-free dairy.

Earlier this week, the Agriculture Department sent a social media post showing Trump with a glass of milk and a “milk mustache” that declared: “Drink Whole Milk.”

The change could take effect as soon as this fall, though school nutrition and dairy industry officials said it may take longer for some schools to gauge demand for full-fat dairy and adjust supply chains.

Long sought by the dairy industry, the return of whole and 2% milk to school meals reverses provisions of the Healthy Hunger-Free Kids Act championed by former first lady Michelle Obama. Enacted more than a dozen years ago, the law aimed to slow obesity and boost health by cutting kids’ consumption of saturated fat and calories in higher-fat milk.

Nutrition experts, lawmakers and the dairy industry have argued that whole milk is a delicious, nutritious food that has been unfairly vilified, and that some studies suggest that kids who drink it are less likely to develop obesity than those who drink lower-fat options. Critics have also said that many children don’t like the taste of lower-fat milk and don’t drink it, leading to missed nutrition and food waste.
