"Dieticians" are widely discredited in the world of real nutrition, and the dietician community has yet to even acknowledge any qualitative difference between DEAD foods and LIVING foods. Dieticians are all about counting calories, and they couldn't care less where they come from. These are the morons who actually tell cancer patients to drink Ensure! (Yeah, seriously...)
I'm not sure why anyone would even want to be labeled a "dietician." It's sort of like being called a "retard" in grade school. Because, of course, the nutritional knowledge of dieticians is rather retarded, as in "lacking in development." It's basically stuck in the dietary "science" of the 1950's, when scientists thought there were only 4 vitamins.
