The sad truth about doctors is this:

They do not receive nutritional training at all. Preventive medicine is not taught in medical schools. (Dr. Weil is trying to get Harvard to change this policy).

And what is worse? Doctors receive very little training in pharmacology....one course I believe.

Over time they have learned to rely on drug reps...in the past these salespeople were pharmacists and doctors themselves.
But starting in the 90's, this changed. Mega bucks started to drive products. Blockbusters like Zantac were among the first.
Now Drug reps are mostly glib talkers, maybe with a degree in business, some with none. They are told what to say, and how to respond. Pharmacists and doctors no longer are in the field seeing doctors, and because of their training are hesitant to LIE and deceive. There is a forum for these people now...
cafepharma.com where they talk about their jobs and doctors and what all. Their language is horrible, there is swearing there and rude attitude. Look it over some time when you have a free moment, and you will see why we have the drug crisis we do now.

And these are the people who convince doctors to give their patients all those strong drugs, without qualms. Negative studies are withheld (sometimes released after patent expires),
studies are skewed by the drug companies, and even doctors names are stolen on ghost written papers, and handed to your doctor as proof of how great the new drug is! It has turned into a shabby situation. And our FDA does nothing anymore since 75% of its income/funds come from drug companies!

Sorry but that is my rant/vent for the day.
