Eggs contain dietary cholesterol (as does liver and some shellfish), but you can eat as many as you want as long as you have a healthy diet and try to avoid saturated fats. According to the FDA the maximum daily amount of cholesterol should be less than 300 mg for a 2000 calorie diet. According to the Mayo Clinic a large egg contains 213 mg of cholesterol. Doing the math that would mean about 1.5 eggs a day if you ate nothing else that contained cholesterol.

Egg yolks contain seven vitamins: B6, folate, B-12, A, D, E and K. Of those, vitamins A, D, E and K are found only in egg yolks and not in egg whites. Egg yolks are one of only a handful of foods in which vitamin D is naturally found. Egg yolks also have minerals: calcium, magnesium, iron, potassium, sodium and selenium. Although both the egg white and egg yolk contain these minerals, the yolk has larger amounts of most. For example, 90 percent of an egg's calcium is in its yolk; 93 percent of its iron content is in the yolk, with just 7 percent in the white.
