There is a limit to everything, too much is too much, and too little is not enough. It should be said that an egg a day is a good choice early, but it should be noted that you should not only eat foods with high protein content, such as eggs and milk, but you'd better add some bread or something in the morning, because if you only eat high-protein foods, then in order to meet your energy consumption in the morning, protein will be consumed and converted into energy, so the benefits of high protein to your health will be gone. Why not eat raw eggs? Protein is rich in human body. Eggs are also a good source of vitamins and inorganic salts and a kind of food with high nutritional value. Some people like to eat raw eggs. I think the nutrition of eggs is destroyed after they are cooked. I think it is better to eat them raw than cooked. In fact, this way of eating is not only useless but also harmful. First, eggs are produced by the ovaries and cloaca of chickens, with high bacterial content, so the surface of eggshells and even yolk may have been contaminated by bacteria, which may easily cause parasitic diseases, intestinal diseases or food poisoning if eaten raw. Second, raw eggs have a fishy smell, which can inhibit the central nervous system, make people lose appetite, and sometimes make people vomit. Third, raw egg white contains a substance called avidin, which prevents the human body from absorbing biotin contained in egg yolk.
