This way of eating is 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 will hinder the absorption of biotin contained in egg yolk.

After eggs are cooked, they can kill bacteria inside and outside the eggs and destroy avidin, so eggs should not be eaten raw. Disadvantages ~ ~ Some people drink raw eggs and think they have high nutritional value. In fact, this is not correct. This has to start with the composition of eggs. The main ingredient of eggs is protein, and protein is composed of various amino acids. Its molecules are very large and must be digested by the stomach and broken down into tiny amino acids before being absorbed by the human body. After the eggs are cooked, the dense protein becomes loose, which makes the stomach and intestines easy to digest and absorb. Secondly, the egg white of raw eggs contains a lot of anti-biological proteins and anti-trypsin. The combination of antibiotic protein and biotin will make biotin a substance that the human body cannot absorb. Anti-trypsin can destroy trypsin in human body and hinder protein decomposition, which is harmful to human body. However, after the eggs are cooked, this anti-biological protein and anti-trypsin are destroyed. Raw eggs also contain an egg essence, which can make the vitamin B in protein lose its efficacy and cause diseases such as hair loss.

From the perspective of food hygiene, drinking raw eggs is also unsanitary. About 10% of fresh eggs contain eggs of bacteria, molds or parasites, especially salmonella, which can make people sick. If the eggs are not fresh, the proportion of bacteria will be higher. At present, more than 1000 species of salmonella have been found, some of which can live in the intestines and ovaries of chickens, ducks and other poultry. In the process of egg formation, Salmonella can directly enter the egg from the ovary. When laying eggs, the surface of the eggshell will also be contaminated by Salmonella in the anus and invade the eggs through the small holes in the eggshell. However, Salmonella is afraid of high temperature. After the eggs are boiled for 8- 10 minutes, Salmonella will be destroyed inside and outside. Therefore, it is unscientific to eat eggs raw, no matter from the nutritional components of eggs or from the perspective of food hygiene.

~ ~ ~ Some people think that eating eggs raw can get the best nutrition. In fact, eating raw chicken has many disadvantages and is very harmful to people's health.
