I wouldn't argue with that principal and, like anything in the media these days, one needs to look for the balance in any content. In this case the 'doctor' has patients and has quoted reliable sources of research. On the other hand he is a statin taker (and therefore 'pro statins' - and he is pushing his multivitamins. However, I found the content to be quite well presented and overall quite balanced.
I wouldn't 'diss' something just because it was on You Tube; I have have found very good dietary information and quite enjoy watching Dr Eric Berg and Barbara O'Neill....... I am not a blind follower of either and I am sure someone will post derogatory reports about both of them (Wikipedia actually crucifies her with this description "is an Australian alternative medicine personality, known for promoting dangerous and unsupported alternative medical practices and ideas"). I listen to what they have to say and take away the bits that fit with my own research and life style.
