A typical 1 large white serving of egg white contains 3.6 grams of protein (10.9 g per 100 g), which makes it a moderate source of protein. That covers roughly 7% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
About 84% of the calories in egg white come from protein, which makes it extremely protein-dense - close to the practical ceiling for a whole food. Foods in this band are the ones that let you raise your protein intake without raising your calorie intake much at all.
Among the 20 eggs in the database, egg white ranks 16th by protein per serving, and 568th out of all 796 foods on the site. Set against cooked egg white, another egg entry in the database, a serving carries about 0.1 g more protein (cooked egg white has 3.5 g per 1 large).
It is a complete protein - it supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own. The serving above is counted by piece at 33 g. Because pieces vary, the per-100 g figure is the one to use when comparing this against a food measured a different way.
