Nutrients in an egg

Egg is known to be the best natural protein food for humans after mother's milk.

Amino acids are important as they are the building blocks of the body.

One egg contains about 6.3 grams of protein. The white contains 3.5 grams of protein while the yolk contains 2.8 grams. The white contains more than half the egg's total protein, niacin and riboflavin.

The yolk contains approximately 190 mg of cholesterol and 5 gms of fat and 1.5 gms of saturated fat. Egg yolks are one of the few foods that naturally contain vitamin D. The yolk also provides vitamin B 12 and folic acid.

Egg yolk contains carotenoids, essential fatty acids, vitamins A, E, D and K and thiamin, B6, folate and B12.
