this is a well laid out article on how it happens. Mercola has, IMHO, the best perspective on health issues; he speaks in a centered tone and gives facts in an organized manner that make processes easy to understand.
I am glad that we have others that can put information together for our use to better our lives.
I have compared Mercola to a few others that report on similar types of information, they always have a bias that is not centered and as factual. The "mind-set" of wholeness is unique to a few, but becoming more mainstream as time goes by. My hope is that one day the wholeness concept will override all biases and politics of government and health care systems.
