Yep, but the FDA allows people to sell ice cream that has no cream in it.

Usually these concoctions have whey in them, because the FDA mandates that in order for it to be called ice cream, it must have some milk product in it.

(Whey is the stuff left over from making cheese. Like buttermilk is the stuff left over from making butter. Both taste similar, sour/tangy. The manufacturers just add lots of sugar to cover up the taste.)
