Are they reviewed or monitored at all, or done on a faith basis by the manufacturer? I have a jar of Trader Joe's Queso Dip in the pantry that I bought on a lark (it does indeed have that wonderful taste of stabilizers that stadium nacho cheese has); but it cites only 15 calories per 2 tbsp - the main ingredient is still cheese (well, frankencheese). I really want to believe it and eat the whole jar with a spoon, but something tells me that someone made a mistake along the line (it also sites less than 0.5% DV fat and 0.0% saturated fat on the label).
I see potential mistakes like this on imported ethnic food a lot (my favorite was a delicious shelf stable saag paneer who's second ingredient was salt, yet cited 0 mg salt).
So yeah, should I be skeptical?
