Whole milk is returning to school cafeterias nationwide after President Trump signed the Whole Milk for Healthy Kids Act, overturning Obama-era limits on higher-fat milk.

Schools in the National School Lunch Program can now offer whole, 2%, 1%, and skim milk, as well as nondairy alternatives that meet nutritional standards.

The law allows parents to request nondairy milk for their children without a doctor’s note and aligns with new dietary guidelines emphasizing full-fat dairy.

Supporters say the change improves nutrition and reduces food waste, while critics question the health impact of higher-fat milk, ABC News has reported.

The policy affects about 30 million students and reverses provisions of the Healthy Hunger-Free Kids Act aimed at limiting saturated fat in school meals.
