The egg yolk is the yellow part of the egg and is a rich source for protein and choline. Choline is an important nutrient for the development of the brain and is especially important for pregnant and nursing mothers for healthy brain development in babies. Eggs are versatile and can be consumed in many ways like pickled, hard-boiled, poached, scrambled, fried and soft boiled. Eggs added to a diet increases the nutritional value. Chicken eggs are the most commonly eaten and they supply all the essential amino acids for humans and provide several minerals and vitamins. They are the most inexpensive single-food source of protein. All the vitamins A, D and E come from the yolk and not from the egg white.
