Marshmallow Fluff (R). Probably one of the worst things for your health. Fattening, sweet, loaded with sugar, a health / fattening/ diabetic nightmare. But... it tastes DAMNED GOOD !! Bread, peanut butter, and a nice coating of "Fluff (R)" makes for one hell of a awesome, sandwich, aka... Fluffernutter. Why is it that all the stuff that tastes good is the worst stuff for your health ?? :(
