I would like to underline your mention that it is the oxidized oils that cause problems in the circulatory system, whether it is veins, arteries or the heart. When cholesterol (or proteins or phospholipids), as an emulsifying agent, is transporting damaged (oxidized) oils in the blood, serious damage occurs. The lining of the circulatory system is scarred. From there it is down hill, as the body attempts to cover and then repair the scar, but in the process you have plaque, occlusion, loss of flexibility, etc. It's a downward spiral. All from eating oxidized fats, whether monounsaturated like olive oil, or polyunsaturated like fish oil. Cholesterol is only a transport mechanism. It does no damage by itself. It takes the ruined oil to cause the damage.
