I keep thinking of a comment on another thread about something like this that said, "Well, maybe we're not measuring the right things." We keep thinking we can segment out parts of a whole and prove it's the same. We don't have the big picture. Eating an orange will always be healthier than popping a vitamin C pill. The orange is much more than just vitamin C, and we do not know what part those other things play, but nature does nothing without reason.
So to me to say that there is no difference, means that we are simply measuring the wrong things.
