Egg white, also known as "protein" or "egg white", is the transparent liquid part around the yolk in an egg. Egg white was originally the cytoplasm of single-celled eggs, and its purpose was to provide nutrition for developing embryos. This is why protein is rich in nutrition and can be used as an ideal nutritional tonic.
If you eat at night, you won't gain weight, but it's bad for your stomach. It is more appropriate to eat two.
Extended data:
Egg white can not only whiten skin, but also make skin tender and remove dead skin. This is because it is rich in protein and a small amount of acetic acid and lysozyme. Protein can enhance the skin lubrication, acetic acid can protect the skin slightly acidic, lysozyme can sterilize. Both can prevent the skin from being infected by bacteria. In addition, egg white also has the functions of clearing away heat and toxic materials and enhancing skin immune function.
