Remember when folks avoided eggs especially the yokes because of cholesterol? My wife never bought it. She said, "How can a food containing all ingredients necessary for life be harmful?" It looks like she may have been right. Choline helps move cholesterol through the bloodstream safely. Lecithin helps emulsify fats which prevent them from clumping together. Lutein and Zeaxanthin help helps reduce oxidative damage and oxidized cholesterol is harmful to arteries. Although they contain cholesterol this amount does not significantly raise cholesterol.
