The Incredible, Edible Egg Yolk - Cholesterol

An egg yolk contains cholesterol as well as saturated fat whereas an egg white contains zero fat but 4 times more protein. If your cholesterol levels are already high, refrain from having more than 200 milligrams of cholesterol (a little more than 1 egg yolk) in a day. A safer option would be to avoid eating more than 2 egg yolks per week.
