Protein is indispensable for muscle growth. The greater the muscle circumference, the more protein you need. Protein in eggs is closest to human needs, so it is also the easiest to absorb! Of course, it also has something to do with cooking skills. Boiled eggs are the best cooking if calculated by percentage. It has the highest absorption and utilization rate! Therefore, bodybuilders will eat a lot of protein and seldom eat egg yolk, because the fat content in egg yolk is relatively high, and bodybuilders need pure muscle, so they don't want to eat too much fat. Eating raw eggs is actually unscientific, because raw eggs contain biotin, which will hinder the digestion and absorption of protein, and undercooked eggs also contain parasites, which are harmful to human health. So it is not recommended to use raw eggs.
