"Natural" is a terrible word for describing things when you are trying to make a point. It doesn't mean anything. Natural things can be safe or unsafe, well tested or unknown, healthy or unhealthy, better or worse.

I really wish people would use the actual comparison they are trying to make when they use "natural" - say "food that people haven't tried living on for extended periods" or whatever.

Natural has become an advertising buzzword designed to trick people into thinking something is good because people associate it with a bunch of stuff that "Natural" does not imply.
