It is not okay to eat eggs that are not fully cooked. The International Health Organization warns that because eggs carry salmonella and E. coli bacteria that are deadly, the public, if ignored, could be killed by eating half-cooked eggs.?

One of the hazards of undercooked eggs

Eggs carry bacteria during the formation process, and undercooked eggs can't kill the bacteria, which can easily cause diarrhea. And raw egg protein structure dense, a large part can not be absorbed by the body, only after the cooked protein becomes fluffy, the human gastrointestinal tract can be digested and absorbed. Therefore, eggs should be eaten after high temperature, do not eat uncooked eggs, not to mention raw. Eating uncooked eggs can easily lead to bacterial poisoning.

Two, the time to cook eggs

If the eggs are cooked in boiling water for more than 10 minutes, a series of chemical changes will occur inside. The protein structure becomes tighter and is less likely to come into contact with protein-digesting enzymes in the gastric juices, so it is more difficult to digest. The protein in the egg contains more methionine, and after prolonged heating, it will break down sulfide, which reacts with the iron in the yolk to form iron sulfide that is not easily absorbed by the human body, resulting in more nutritional loss. In terms of nutrition, boiled eggs within 10 minutes, the highest digestibility, nutrients basically no loss.

Three, the nutritional value of eggs

1, eggs are better brain food

Every 100 grams of eggs contain 11 to 15 grams of fat, mainly concentrated in the yolk, but also very easy to be digested and absorbed by the body, the yolk is rich in lecithin, steroids, lutein and calcium, phosphorus, iron, vitamin A, vitamin D and B vitamins. These ingredients are very beneficial to enhance the function of the nervous system.

2, eggs are rich in lecithin

Egg yolks contain more cholesterol, per 100 grams can be as high as 1705 milligrams, therefore, many people, especially older people are wary of eating eggs for fear of eating eggs caused by cholesterol increase and lead to atherosclerosis. In recent years, scientists have found that eggs contain more cholesterol, but also rich in lecithin. After lecithin enters the bloodstream, it will make the particles of cholesterol and fat smaller and keep them suspended, thus preventing the deposition of cholesterol and fat in the blood vessel wall. Therefore, scientists believe that for the elderly with normal cholesterol, eating 2 eggs a day, with a maximum increase of 2 milligrams of cholesterol in 100 milliliters of blood, will not cause vascular sclerosis. But should not eat more, eat too much, unfavorable gastrointestinal digestion, resulting in waste, but also increase the burden on the liver and kidneys. Each person to eat 1 to 2 eggs per day is appropriate, which is conducive to digestion and absorption, but also to meet the needs of the body.

3, eggs are ideal for human natural food

In eating method should also pay attention to science. For the elderly, eating eggs should be boiled, lying, steaming is good, because frying, frying, deep-fried although delicious, but more difficult to digest. Such as eggs processed into salted eggs, its calcium content will increase significantly, can be increased from 55 mg per 100 grams to 512 mg, about 10 times as much as fresh eggs, especially suitable for osteoporosis of middle-aged and elderly people to eat. It should also be reminded that never eat raw eggs, some people think that eating raw eggs is good nutrition, this view is not scientific.
