The primary protein source in fish is fish protein, which consists of essential amino acids and has a high biological value. Fish is an excellent source of complete protein, providing all the amino acids that the human body cannot produce on its own. Besides its protein content, fish is also rich in omega-3 fatty acids, vitamins, and minerals, making it a nutritious dietary choice. Fish such as salmon, tuna, and cod are particularly valued for their protein and health benefits. Incorporating fish into one's diet is often recommended for maintaining overall health.
