However unfiltered coffee had many oils and acids that over time could build up cortisol levels in the blood stream leading to hardening of the cell membranes and resistance to insulin along with plaquing of the arteries. Don't remember all the details but that was the gist of it. There is a brief blurb out on Fox News with the short answer by him on the direct impact on the heart as regards caffine however that does not address the acids and oils that are covered in the complete ansewer.
On the various oils in coffee, the temperature at which they are released along with their impact on flavor my kid brother is the one to talk to. At culinary school he won an Award of Excellence from the National Restaraunt Association for his coffee brewing skills. His award for being able to bone out a whole chicken in less than 30 seconds would caution you not to startle him in a dark alley.
The other thread is not lost that is why I provided the "Read More" link to it in my first post.

Coffee oils and acids can harden cell membranes? That's definitely a first I've heard of that because if coffee oils affected cell membrane permeability the first thing it would affect is your digestive system and you'd simply stop absorbing the coffee oils in the first place. Cell membranes are pretty much self self regulating, to have chemicals be able to significantly affect animals on the cellular membrane level would mean body chemistries so alien that you'd be facing other more serious issues like neurochemical or ionic imbalance. As for building up insulin resistance I don't think it's the coffee that's doing it.
I'm highly dubious about this doctor's research especially the fact that he's going on Fox News to discuss it.
And as far as people claiming coffee oil raises cholesterol. The studies are all over the map on that one. But one thing is for certain, the French use French press and are generally lower in overall cholesterol levels, while Americans filter their coffee and are higher in overall cholesterol levels. Some people may see a link. But the only link I see is just Americans eat unhealthy foods which is causing the high cholesterol and coffee at worst can be eliminated from negative health impacts and at best contribute to overall health.
The fact is if you have high cholesterol trying to blame it solely on coffee is irresponsible and short sighted.
