Which one of the following is considered as the easily digestible source of protein?

Egg albumin is considered the most easily digestible source of protein among the given options. Animal-source proteins generally exhibit high digestibility, ranging from 90% to 100%, compared to plant proteins like soybean, which average around 70% [t2]. Specifically, egg proteins are characterized by an exceptionally high digestibility rate of approximately 97% to 98% and a high biological value of 94% [t1][t5]. While fish and red meat are also high-quality animal proteins with high biological values [t9], egg albumin is often used as the gold standard in nutritional science due to its superior amino acid balance and minimal connective tissue compared to meat [t1][t2]. Red meat contains complex fibers and fats that can make it relatively harder to digest than the simpler structure of egg white protein [c1]. Therefore, egg albumin is the most efficient and easily absorbed source [t5].
