Protein provides the building blocks for muscle and is essential for keeping up energy levels and improving immune function. Eggs are a great source of low-cost, high-quality protein, providing approximately six grams of protein per egg.
But that's not all. Eggs pack in more than just protein. Egg whites are an excellent source of protein and riboflavin. Egg yolks are a good source of protein, iron, vitamins A and D, phosphorus, and choline. Choline is a key component of cell membranes, and is particularly important for brain function and health.
