In this post, Dr. Berg describes the numerous health benefits of eating eggs: One of the key reasons that I consume eggs on a regular basis is not only do I enjoy it, but eggs have the greatest anabolic effect out of all the food options around. Anabolic means that it's contributing to growth. Building muscle protein.
48% of egg actually turns into your body tissue and that's pretty much the highest, not counting breast milk. Moreover, cholesterol and fat in the yolk actually help in the anabolic effect.
Egg whites have really low amounts of essential fatty acids, while egg yolk contains most of the nutrition.
