Some people like to drink raw eggs, thinking that they can supplement the body and are easy to digest, but it is actually counterproductive. Raw egg white contains avidin and antitrypsin. Avidin can combine with biotin in intestine to form compounds that are difficult to be digested and absorbed by human body, resulting in the lack of biotin in human body. However, antitrypsin can inhibit the activity of trypsin and hinder the digestion and absorption of protein. Eating raw eggs is not good for people. After the eggs are cooked, these two harmful substances are destroyed, which makes the dense structure of protein loose and easy for human body to digest and absorb, so we should eat boiled eggs. But don't overheat the eggs. Overheating will cause protein to coagulate excessively, or even harden and toughen, forming lumps, which will affect appetite and its digestion and absorption.
