Why Are Egg Whites So Popular?

People love egg whites because they are a “complete protein.” This means they have every single building block your muscles need to grow.

2. They Are Safe: Most egg whites in a carton are “pasteurized.”³ This means they were heated to kill germs, so they are safe to use in shakes or scrambles.

3. They Are Cheap: Compared to steak or salmon, egg whites are one of the most affordable ways to get high-quality protein.
