The egg yolks and whites have the same amount of protein.
This was certainly a surprise to us! Each egg white and yolk contains 3 grams of protein. So, while egg whites are traditionally associated with protein, they don't have a significant advantage over their yellow counterpart. The main distinction is in the number of calories. A single yolk contains 3 grams of protein for 60 calories, whereas an egg white contains 3 grams of protein for only 15 calories.
