Most healthy people can eat up to seven eggs per week without increasing their risk of heart disease. In fact, eggs are a nutritious food, relatively low in calories and saturated fat, and rich in protein, vitamins, and minerals. Some studies have even shown that this level of egg consumption might help prevent certain types of stroke and a serious eye condition called macular degeneration that can lead to blindness. Seven medium eggs contain 453 calories, with 63% fat, 2% carbs, and 35% protein.
