I want to re-iterate this, because my post came off more negatively towards MD's than intended. You are absolutely correct that most of the MD's I have met are very passionate about helping people. And what bothers me is partly this...
...but even more when an MD actively uses their status as "Doctor" to promote something that would otherwise be dismissed as quackery. Basically, Dr. Oz going on a TV show and saying the Idaho ragweed is a miracle for weight loss is 9,000 times worse than walking into the hospital cafeteria and seeing Cardiologist X with a Mountain Dew and fries.
Point being, I didn't mean to be negative about MD's in general, moreso the specifics of doctors like Dr. Oz that go out of their way to promote questionable or nonsense "advice" for personal gain that they are either a) ill-informed about or b) well-informed but intentionally deceptive about.
I think I made that point rather clumsily. My bad.
