Here is a cardiologist/lipidologist and an MD with an interview about the subject that is interesting. Take it for what it is worth.

When it comes down to it, we have to believe someone. Most of us don't have the time or knowledge or maybe even the ability to ferret this information on our own. And we don't live long enough or enough lifetimes to figure it all out on our own. So most of us have to decide what and who to believe. I like these two guys pretty well. They don't know it all and they no doubt still make mistakes and still have errors in their conclusions. But I think they have more right than they do wrong. And I think a lot of modern dietary information and experts have had it wrong for the last 50 years.
