Animal protein is a type of protein derived from the tissues and fluids of animals. The main animal protein sources include meats, poultry, seafood, eggs, and dairy products. Animal proteins are an excellent source of many nutrients, including certain vitamins, minerals, and antioxidants. They also contain all the essential amino acids needed for human health. Animal protein benefits include improved muscle mass, stronger bones, better blood sugar control, and a lower risk of chronic diseases like heart disease and cancer. However, animal based protein can also be high in saturated fat and cholesterol.
