Well, it's not necessarily just the direct fault of the person in-question (Doctor, Nutritionist, whatever). The problem goes a bit deeper than that, there's a reason pretty much ALL of America was and in many ways still is on a "low fat" kick. Visually, it makes sense. Eat fat, get fat. Eat cholesterol, get cholesterol. How many people actually study lipid and glucose metabolism specifically? Mostly just the scientists in those fields, and there's bevies of evidence they have. Problem is outside of their own publications, you won't see a lot of it unless you know which places to go to. It's akin to that there's arguably an ivy league education sitting in any City Library, but how many people have it in them to comb through all that? And without the guidance, it's easy to get confused.
It's pretty amazing how many dogmatic notions exist about this field that either defy biological function, or themselves were based on faulty evidence to begin with. At the end of the day it's pretty much impossible to convince someone of something they don't want to believe. So the way I see it we can simply relay the information, and let the chips fall where they may in terms of what decisions people make.
