My cardiologist and most other doctors I have talked to, point at a dietary influence to my condition(I take lipitor and my cholesterol level is 90 - my triglycerides are high). I hate fish. As to what I am doing in this, I merely pointed out that the Dr. who headed the "quackery" site, lost a suit involving a defamation.
Ah, but the doctor who lost is the one who was suing. He has not been successfully sued for calling people quacks.
Perhaps he lacks good judgement in when to pick fights. I don't know. I don't need his opinion to know that diet is not the cause of all disease.
