The problem with taxing "all junk food" is that the devil is in the definitions. We can probably all agree on the obvious examples like soda and potato chips, but about the Chinese hot bar at Wegmans? It's certainly worse for my body than the sushi next door, but whether you would call that junk food or not is more a reflection of your values. At least sugary soda is demonstrably problematic, as the human body doesn't sate its appetite from refined sugars as the caloric equivalents of proteins or fats would.
