Animal proteins are proteins derived from animal sources, including meat, fish, eggs, and dairy products. They are considered complete proteins because they contain all nine essential amino acids that the body cannot produce on its own. These proteins play a crucial role in building and repairing tissues, supporting immune function, and producing hormones. Common sources of animal proteins include chicken, beef, salmon, and yogurt. Consuming a variety of these foods can help ensure adequate protein intake, which is important for overall health. However, it's essential to balance animal protein consumption with plant-based proteins for a well-rounded diet.
