All the cholesterol in an egg is in the yolk. Half the protein is also in the yolk. So if you toss the yolk and use the whites, you get no fat or cholesterol and half the protein of a whole egg.
I don`t thing the cholesterol from the eggs will cause so much trouble.... there are new scientific studies that say there is not so much influence by the food.
just remember that cholesterol is a hormon produced in the liver.... and don`t forget about the LDL's and HDL's....
