Dr Marcia Angel (Harvard), wrote in her book, "reluctantly, after 20 years as editor of the New England Journal of Medicine, I have realized MOST medical research, cannot be trusted". (Ex the "food pyramid is acutally upside down" and hundreds of other examples).
Pharma, who "owns congress" according to several congressman and is by FAR THE LARGEST LOBBY IN D.C. and largest Media advertiser, also funds most "research", writes all the medical books and otherwise funds all medical universities to some degree or other...no industry has been found guilty of FRAUD or fined as much as pharma but its calculated into their business models (as is population reduction all the elite keep obsessing over).
Great video, but focusing on all the fraudulent studies (like Upjohns obviously phony IBU STUDY from 1980s and acetaminophen studies), would be a much much more popular channel i think... but does anyone have the guts to do it?
