Great question eggs are actually highly nutritious, as they contain almost a little bit of every vitamin and mineral including: vitamin A, folate, vitamin B5, vitamin B12, vitamin B2 phosphorus, selenium, vitamin D, vitamin E, vitamin K, vitamin B6, calcium and zinc. They are also a great source of protein and healthy fats.
