Washing eggs with water instead of boiling or frying will not increase the nutritional value of eggs, but it will have certain health risks. Salmonella infection was mentioned by many people before, but the severity was not said. After being infected by Salmonella, symptoms such as abdominal pain, diarrhea and fever may occur, which may easily cause serious pathological changes in children, the elderly and pregnant women, and the most serious may be fatal. Infected persons and carriers may easily become the disseminators of germs.
There is another risk that many people have not mentioned, that is, avidin in eggs will combine with biotin in food, resulting in its inability to absorb, resulting in biotin deficiency. Biotin is an essential B vitamin, also known as vitamin B7, which plays an important role in human growth, development and maintenance of physiological functions. Lack can lead to eczema, dermatitis, alopecia, muscle pain and other symptoms. To inactivate avidin in eggs, it is necessary to boil the eggs for at least 4 minutes, which is difficult to achieve with hot water brewing.
Of course, egg water is not a poison, and it is impossible to be poisoned as soon as you eat it, but it is certain to increase health risks. It's not worth the risk for a less outstanding taste and non-existent health care function.
Eggs can be contaminated by salmonella and staphylococcus, and people who eat eggs with pathogenic bacteria may develop salmonella gastroenteritis or staphylococcal enterotoxin poisoning.
Boiling water is still not enough to kill some germs, and the yolk bacteria of raw eggs are the most. It is recommended that the elderly, children or people who are weak eat as little as possible.
Egg water still has the taste of raw eggs to a certain extent, which will inhibit the central nervous system, make people lose appetite and sometimes make people vomit.
Egg white contains avidin, which will interfere with the absorption of biotin in the intestine if it is not completely inactivated, but there is no need to worry that avidin can be inactivated after high temperature heating to ensure the normal absorption of biotin in the intestine. However, direct washing with boiling water may not completely inactivate avidin and is not recommended.
