1, yolk is rich in nutrition.
Egg yolk contains antioxidants, vitamin B 12, vitamin A, iron, selenium, biotin, phosphorus, choline and various other micronutrients. Choline, in particular, is an important nutrient to promote brain function, nervous system and body detoxification.
It is unscientific that cholesterol in diet can lead to heart disease.
Many people have this cognition that cholesterol in the diet is harmful and should be avoided as much as possible, but the fact is that the human body needs cholesterol, which has many important functions, such as building and repairing cells. Studies have shown that there is almost no connection between dietary cholesterol and high cholesterol levels in the blood. The liver itself produces cholesterol, so if there is more cholesterol in the diet, the liver will produce less cholesterol.
3. Eggs are one of the most perfect forms in protein.
Eggs are very popular in the field of fitness. They are an important source of protein, rich in all essential amino acids, and each egg contains about 6 grams. Vegetarians and meat eaters can get protein from eggs.
4. Eating comprehensive food helps digestion.
Eating some parts of food, such as only eating egg whites, will make the body feel that it has not eaten all the food. In other words, the body will have a desire for other parts of the food, so it is best to eat the food completely.
The whole egg is delicious, too.
Eating only egg white may be boring, and even make people start looking for "substitutes" for liquid eggs. They lose nutrition during processing and are not as delicious as eggs themselves.
Extended data
1, overnight eggs and tea eggs are not good for your health.
Eggs that are not fully cooked will breed bacteria overnight, and eating such spoiled eggs is harmful to health. Because protein has been destroyed during cooking, and it is overnight, the nutritional value will be reduced a lot.
In the same way, we should also pay attention to eating less tea eggs and cooking them once. Because the substances in tea mixed with protein will produce harmful substances.
2. Don't eat raw eggs
If you think eating raw eggs is more nutritious, you are all wet! Immature eggs contain a lot of E.coli. If eaten undercooked, it is easy to cause diarrhea. Therefore, eggs should be cooked at high temperature and eaten after killing bacteria.
In addition, raw eggs contain avidin, which will affect the absorption of biotin in food, leading to "biotin deficiency" such as loss of appetite, general weakness and muscle pain. There is also anti-trypsin, which will destroy the digestive function of the human body. Another thing to note is that when you beat eggs, you should be careful of the contaminated bacteria on the eggshell!
Step 3 eat eggs in moderation
Although the experience value of eggs is high, the more eggs you eat, the better. Eating too many eggs can easily lead to overnutrition and obesity. Increase the burden on the liver and kidneys. Excessive protein will overload the urea manufacturing system, and excessive intake of protein will produce a large number of chemicals such as ammonia, hydroxyl and phenol in the intestine, which is very harmful to human body.
Abdominal distension, dizziness, limb weakness, coma and other symptoms are likely to occur, which is often called "protein poisoning syndrome".
It is best not to soak the eggs in cold water after they are cooked.
Soaking boiled eggs in cold water can really cool the eggs quickly. Because the eggshell inner membrane and egg white membrane contract differently when exposed to cold, it is easy to form a certain gap, which makes the eggshell easier to be peeled off. But this ignores the fact that there are a lot of bacteria in cold water.
After the egg is heated, the eggshell membrane that can prevent bacteria from passing through has been destroyed, so that the eggshell vent can no longer stop bacteria, and bacteria can easily take the opportunity to invade the egg, which can be said to be free to come and go.
The correct way is to add a small amount of salt in the process of boiling eggs. Salt can not only sterilize and detoxify, but also form a certain gap between eggshell membrane and egg white membrane due to different shrinkage degrees, which makes eggshell peel off more easily.
