Their is a school of thought, the Heller's are a part of it, that say's that it is not fats (except in large amounts - which isn't part of CAD anyway) that cause elevated cholesterol and later heart disease, but carbs. The reason carbs are a problem is that they keep insulin levels high and this school of thinking says excess insulin is what causes elevated lipids and other heart concerns. You may find it interesting to read "The Carbohydrate Addicts Heathy Heart Program", I sure did.
