Eggs are one of the sources of a perfect protein. The whites have amino acids that our bodies use to make protein more efficiently. Our bodies actually use amino acids better than the protein from protein drinks because it allows our bodies to only make as much as we need instead of flooding our systems with extra products that will just be excreted. Yes, yolks have cholesterol, but it is dietary high density cholesterol instead of the LDL that you know of as "bad" blood level cholesterol. HDL actually helps decrease LDL levels. Eggs also have two types of carotin for your eyes, and have low calorie counts per serving. Trust me, eggs are a great and healthful source of protein.
