I'm a huge fan of Dr. Esselstyn. I'm also a fan of many of the pioneers that came after him. I'm kind of torn regarding "oils". Esselstyn states "NO OIL, not even Olive Oil".. and many others as well. But we also have another train of pioneers that are saying "Oil is fine as long as it's "virgin" or "cold pressed" and not "processed".. Any thoughts on this topic?
