The medical profession is VERY good at many things.

But it is a for profit business for the most part, much more so now than when I was a kid and often hospitals were non-profit organizations. That makes it have conflicts of interest all too often. Treatments are more profitable than cures or prevention.

Nutrition they just pretty much suck at all around.

Most of the doctors I follow, I would say at least 3/4 of them, came to their alternative way of thinking after being sick in one way or the other and having conventional medical wisdom fail them. So they looked for alternatives through research and cured themselves, which opened their eyes toward changing their medical practice to alternative ways of thinking and practicing medicine.
