It is not possible to generalize how much protein is in an egg. In general, every 100g of egg contains 12.7-14.4g of protein, with ordinary eggs (red and white) containing slightly less protein than eggs from the soil. How much protein is in an egg has a lot to do with the size and variety of the egg, so it is impossible to generalize. Currently often eat eggs have ordinary eggs (red skin, white skin), earth eggs two categories, according to modern nutritional research data show that every 100g of ordinary eggs (red skin, white skin) and earth eggs contain about 12.8g, 12.7g, 14.4g protein respectively. Protein is not only an important component of the body’s tissues and organs and cells, or the main raw material for the repair and renewal of human tissues, appropriate to eat a little bit of eggs on the human body is good, but because the eggs also contain cholesterol and fat, can not be ingested too much.
