Egg Yolks
The yolk or yellow portion makes up about 33% of the liquid weight of the egg
and contains all the fat in the egg. The yolk is extremely high in
cholesterol, containing more than two-thirds of the recommended daily limit of
300 mg! However, the yolk has many health strengths necessary for immunity,
healthy skin, nerves and vision. The yolk contains good amounts of B Vitamins,
Vitamin A, iron and riboflavin. All the egg's vitamins A, D and E are in
the yolk.
Egg Whites
Egg whites are very low in calories, have no fat, no cholesterol, and are
loaded with protein. Egg whites contain a little over half of the eggs
riboflavin, but none of the other vitamins. The egg white is less likely
than the yolk to harbor dangerous salmonella. Consumption of raw eggs is
highly discouraged due to health risks from salmonella. Egg whites or
yolks should be brought to a temperature of at least 110 degrees in order to
kill Salmonella bacteria.
If you want a really big omelet, one ostrich egg is equivalent to twenty two
chicken eggs.
