"Some older athletic diets use to propose eating just raw eggs. This is a foolish attempt at taking in additional protein. Eating raw eggs (or raw egg whites) will only result in about 50% absorption of the available protein. That means that if you eat enough raw eggs to give you 40 grams of protein, your body will only absorb 20 grams.
Eating just raw egg whites results in the same (or worse). Egg whites have a huge amount of a substance called "avidin," which loves biotin. As a matter of fact, once the avidin-biotin forms a bond, the body can't break it apart. So you will develop a partial or full Biotin Deficiency Syndrome. Cooking your eggs (or egg whites) will quickly denature the protein avidin and will allow you to absorb 98% of the protein. In short, always cook your eggs."
