Answer 1

In the us, the usfda has a loophole where if an item has less than five calories per serving, it can be labeled ‘zero calorie.’ Common example: tictaks. Pure sugar, but around 4 calories per piece. Serving size is one piece, so legally, the factory can print “zero calorie” on the label and not be sued.
