Plumster, can you share the link for this quote? FWIW, I completely agree that vascular disease increases the risk of both CVD and dementia. I remain unconvinced, however, that dietary fat is a primary contributor.
Let me respectfully ask you a very important question. I'm very interested in your response. If I had vascular disease, what would the clinical signs and symptoms be? How would I know?
Also, it's been suggested (proven?) that one can be insulin resistant in the brain but not peripherally. Is the same true for vascular disease? I would think possibly so. An MRI can show microvascular ischemic disease. Mine didn't show it and my CAC is zero, but I'm pretty liberal (not crazy high) with fats.
I would think saturated fat would be important to ensure structural integrity in neurons? I think of omega 3/DHA as allowing extremely rapid signaling (don't have where I read something like that???) while being highly vulnerable to oxidative damage, while saturated fat would provide more structural integrity with less vulnerability ... but these are my uneducated words ... I don't know.
