If you have a very serious medical condition, like cancer, and you talk to a doctor about things like taking vitamins, most of them will pooh-pooh it as if any impact it has is merely a placebo effect. Using nutrition, exercise and stress management as part of your defense in the face of something that doctors don't really know how to treat gets dismissed and attacked and basically lumped in with snake oil. In fact, you are basically doing this yourself with your wild misquotes of people here in service of some agenda that has nothing whatsoever to do with trying to comprehend anything being said here, as best I can tell.
