this is not meant to sound bitchy - real question.
Do you call some food "good foods" ? That gives them power too. Furthermore, to make a philosophical point, if some things are qualified as good, there is necessarily a bad food category, otherwise we have no way to define 'good.'
Some foods ARE bad foods. Twinkies? Bad food. (don't pull up the recent news story; tons of problems with that sort of sensationalism). It's sad that we call things that are so full of chemicals* "food" in the first place. If we must refer to them as food, I think they definitely qualify under the "bad food" category. Another example: soda. Phosphorus is bad for bones; the sugar is bad for our teeth. Bad food (beverage, rather).
*yes, water is a chemical, I'm using the word in a conventional sense and not a scientific one
maybe she's born with it, maybe it's chlorine
