High-quality protein refers to proteins that contain all nine essential amino acids needed for human health. These amino acids are crucial because the body cannot produce them on its own, so they must be obtained through diet. Sources of high-quality protein include animal products like meat, fish, eggs, and dairy, as well as some plant-based options like quinoa and soy. Consuming high-quality protein is important for various bodily functions, including muscle repair, immune function, and hormone production. It can also help maintain a healthy weight by promoting satiety. Incorporating a variety of high-quality protein sources into your diet can support overall health and well-being.
