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.
Raw eggs contain anti-enzyme proteins and anti-biological proteins. The former hinders the contact between protease in human stomach and protein, and affects the digestion and absorption of protein. The latter can combine with biotin in food to form substances that the human body cannot absorb. However, the above two harmful substances in raw eggs are destroyed once cooked, which no longer affects the absorption of nutrients by the human body.
Protein structure of raw eggs is dense, and digestive enzymes in gastrointestinal tract are difficult to contact and be digested and absorbed. However, the cooked egg protein structure becomes soft and is easily digested and absorbed by the human body.
About 10% of fresh eggs carry pathogenic bacteria, mold or parasitic eggs. Some parents wash their children's eggs with boiling water and add sugar. Because the germs and parasitic eggs in eggs can not be completely killed, it is easy to cause diarrhea and parasitic diseases. If there is salmonella in eggs, it will also cause food poisoning. Recently, it has been found that there may be 0- 157 enterohemorrhagic Escherichia coli on eggshells. Even if the amount of bacteria is small, laying eggs is enough to cause food poisoning. Some folks use raw eggs to treat constipation in children, which can not only cure constipation, but also infect people and animals with Toxoplasma gondii. The disease is acute, and almost all organs in the whole body are invaded by Toxoplasma gondii, causing lesions and even death in severe cases.
So eggs must be cooked and eaten, and it is best to eat steamed eggs. It is not advisable to wash eggs with boiling water, let alone eat raw eggs.

Why not eat raw eggs?
Protein of eggs is rich in essential amino acids, and its composition ratio is suitable for human needs. 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. After eggs are cooked, they can kill bacteria inside and outside the eggs and destroy avidin, so eggs should not be eaten raw.
Eating eggs raw is harmful to your health and your hair turns white.
Some people advocate natural food too much and eat it directly or simply take it with boiling water without normal processing or cooking. Some people think that eating raw eggs in this way can get the most comprehensive nutrition. In fact, there are bacteria such as salmonella in raw eggs, so eating raw eggs will be harmful to the human body, and eating raw eggs will make your hair turn white.
There is a substance called biotin in the human body, which can hydroxylate and dehydrogenate protein digested and absorbed in the body, and can be transformed into "oral introduction", "oral flowering" and "single quince" to produce melanin.
Raw egg protein contains avidin, which is easily absorbed by human body. Therefore, eating raw eggs often may lead to the decrease (or lack) of biotin, which leads to the decrease of melanin production, and the lack of melanin will make hair lose color, so it is easy to cause hair to turn white for a long time.
At present, there are different opinions about whether stewed eggs with milk are healthy. This question seems to be inconclusive. Most people tend to eat together, but eggs should not be cooked in milk, which may destroy their respective nutrients. Some nutrition experts believe that the elderly, children and other people with weak digestive function of the spleen and stomach can drink milk after eating eggs for half an hour, but most people don't have to. Some experts also believe that milk can be eaten with eggs, because both are high-quality and high-protein foods, and eating together is beneficial to physical fitness and recovery after illness, and it is suggested to eat with some staple foods to make better and more reasonable use of high-quality protein.
