Regardless of shell color, one large egg has about 70 calories, 6 grams of protein, 2 grams of saturated fat, about 185 milligrams of cholesterol, and a long list of other nutrients.
These include lecithin, an important component of cell membranes, and high levels of choline, a nutrient that aids brain development. Egg yolks also contain phosvitin, a protein that maintains healthy skin, and carotenoids—such as carotene, lutein, and zeaxanthin—which have antioxidant properties thought to help reduce the risk of eye diseases like macular degeneration.
