From my limited understanding, cholesterol is a ratio/balance thing... kind of like omega 3 and 6s.

I can tell you that I did find some information about dietary oils and how they affect cholesterol.

Olive oil brings the 'good' up and the 'bad' down.

Grapeseed oil bring them both up.

It was a pretty general study/article and I can't remember where it is right now but I bet you could find it if you googled it.

That being said, dh is slightly high on cholesterol (by one point - which some people scoff at) but we ingest grapeseed oil every day in our house and have done for several years. Still, I did make sure to get some olive oil for him to put on his food instead but he prefers the grapeseed as it's milder.

Oh, I almost forgot all the oils are raw... not heated... that's very important as it turns into a bit of a different beast the minute you heat it up.

That's all I've got on cholesterol and dietary oils.
