The FDA calls it “pasteurized processed American cheese food.” In order for a food product to be a true “cheese,” it has to be more than half cheese, which is technically pressed curds of milk. So each Kraft American single contains less than 51% curds, which means it doesn’t meet the FDA’s standard.
No, it does not.
