Egg whites, readily available from a major retailer, constitute a protein-rich food source derived from eggs. These are sold separately from the yolks, often in cartons, and offer a convenient way to incorporate protein into one’s diet without the associated fat and cholesterol found in whole eggs. A typical example would be a container of liquid egg whites purchased for use in omelets or protein shakes.
Their significance lies in their nutritional profile and versatility. They are a source of complete protein, essential for muscle building and repair. Historically, separating and consuming the white part of an egg has been practiced by athletes and health-conscious individuals seeking lean protein. Furthermore, their availability and relatively low cost contribute to their widespread adoption as a dietary staple.
