A complete egg must have both albumen and yolk!
After the egg protein is eaten and digested in the human body, our body becomes alkaline; while the egg yolk It is acidic after being eaten into the human body. In this way, eggs with both protein and yolk can maintain the balance of our bodies very well, so eating eggs is very good for the human body!
Some eggs do not have yolks, but please don’t worry or be afraid, because the production of eggs is like this: the mother hen produces egg cells (i.e. egg yolks) in the body of the mother hen. If it encounters the sperm of the father rooster, it will A fertilized egg that can develop into a chick). As this egg cell moves in the mother hen's body, the mother hen first produces egg white to wrap the raw egg yolk, and then produces an egg shell to wrap the two, and then the egg will Come to the human world. Haha, so some eggs do not have egg yolks, but have egg whites. The reason is that very few things, such as sand, have entered the mother hen's birth canal, and her body mistakenly thinks that the grain of sand is an egg cell, so it wraps it up layer by layer. Eggs without yolks were born.
Therefore, it is superstitious that the elderly cannot eat eggs without yolks.
Good luck!
