The yolk is where all of the cholesterol (about 185mg) of an egg is found. The American Heart Association recommends keeping cholesterols intake to less than 300mg a day.
Not being aware of your daily cholesterol intake and eating more yolks is almost as bad as smoking for people at risk of heart disease.
you can consume the white as much as you want, but don't take more than 3 - 4 whole egg each week.

hope it hepled
