Eggs are a highly nutritious food, rich in protein, vitamins, and minerals. A large egg contains about 70 calories, 6 grams of protein, and essential nutrients such as vitamin B12, riboflavin, and selenium. The egg yolk contains most of the vitamins and minerals, while the egg white is primarily composed of protein. Including eggs in your diet can support muscle health, improve brain function, and provide a feeling of fullness.
