Correlation does not prove causation, Wenshu
. As I said, you can look at the writings of other experts in this field and they can provide the same information. Kresser's been saying this since before he started "selling more sh!t". Kresser's been working as a clinician for years. That doesn't make him right, but it does hint that he has an idea on what he's talking about and it's not about marketing.
If you don't have data that refutes what he's saying, and you're not disagreeing based on scientific data, then you can not - with any real certainty - make claim that what he's saying is bullsh!t just to sell you something.
Yeah, he's got ads on his site for a nutrition program. If he writes an article on acupuncture, is that bullsh!t too because he's an acupuncturist? He's not marketing any physical products that I can see (except for a book he just wrote in the last month, perhaps).
The whole modern notion we have on heart disease is based around p!ss-poor studies. It's not even about misinterpretation. It's just poor science that gets repeated to infinity because it's become dogma. If you disagree with the dogma, then you risk being ostracized. It's no different than the debate on global warming or GMO. "The science is settled" and if you disagree with that science then you must be a science-fearing loser.
I am not overly familiar with point #1, but points #2 - #4 are all over the medical literature if you want to look it up yourself.
