I used to moderate the Food notesfile on DIgital Equipment Corporation's (DEC's) internal corporate network. It was our company's internal equivalent of the FLDG.
Last time I looked, the legally permitted term by the FDA for Kraft Singles was "Pasteurized Process Cheese Food". That was the closest that they were willing to permit the concoction to be called "cheese".
There was some discussion on the Food notesfile as to what "Cheese Food" meant.
My favorite comment was this:
"I don't know why they call it 'cheese food'. I put some in my refrigerator, and the cheese won't touch it."
Sorry--to me, Kraft green-can Parmesan smells like baby's barf. I would eat Kraft Singles if the alternative were starvation.
Velveeta is an abomination before the sanctity of creation. It has no right to exist in a sane and moral universe.
