I would generally agree with most points in the article.

One point that was made, almost in passing, is the notion of deceiving the patient into do the "right thing". I find that notion offensive. The doctor should INFORM the patient of everything, including the pros, cons, and likelihoods, and options (including the option to do nothing). Then let the patient decide what course of action they want to pursue.

Somewhat tied in with this is how the current medical establishment "educates" people into eating the very things that will make their condition worse. At least this is slowly beginning to change.
