Dietician : Nutritionist :: Dentist : Tooth-i-ologist.
That being said, all things being equal, I'd take a brilliant dietician (who has been trained in the whole system and science), over a brilliant nutritionist (who might only be great programming in one or two languages).
again, imh(uneducated)o.
No 'self taught programmers' use their own "base 3 logic system" fighting against the "base 2 conspiracy".
Some of the things nutritionists believe are at odds with basic science, e.g. nutritionists who think you should eat green veg because the chlorophyll will oxygenate your blood... ignoring the fact that chlorophyll works in the presence of light, and there is no light inside your body...
Let's be clear here, Nutritionism is up there with Astrology, Creationism, Flat Earth Theory, Crystal Healing, and the Magic Power of the Stars to Heal You.
A Fitness Trainer is not a good analogy either, because you can't stay in business long as a fitness trainer if you have no idea of the basics of fitness or anatomy. E.g. a fitness trainer who said that you breath through your feet, so you should wear sandals when running knows as much about biology as a nutritionist who thinks chlorophyll can oxygenate your blood. However the magic super food nutritionist had a prime time TV show! High ranking, popular nutritionists can believe things that are nonsense, what hope do you have about a local nutritionist?
I'm not sure this qualifies Nutritionists as "real" for any value of real I personally care about ... then again I haven't clicked, because I don't really want to know about people who'll likely all hate me for eating too much steak ;)
However it 'exists' and is true as much as Astrology and Creationism.
