Eggs and soy milk with food
Drinking soy milk in the morning when you eat an egg, or eggs in the soy milk to cook is the diet of many people. Soymilk is sweet and flat in nature, with many nutrients, drinking alone has a strong nourishing effect. But there is a special substance called trypsin, which is combined with the egg white ovalbumin, which will cause the loss of nutrients and reduce the nutritional value of both.
Eggs and rabbit meat with food
Eggs can not eat with rabbit meat. Eggs eaten with rabbit meat can irritate the gastrointestinal tract and cause diarrhea.
Eggs are stored horizontally
Fresh eggs have a thick egg white that effectively holds the yolk in the center of the egg white.
When stored for a long time, especially when the outside temperature is high, the egg white mucus will slowly shed some of its water under the action of protease and lose its ability to hold the yolk in place.
At this point, if the eggs are placed horizontally, due to the specific gravity of the yolk is smaller than the egg white, the yolk will float, close to the eggshell, into a sticky shell egg. So the eggs should not be stored horizontally.
Eggs dyed red with red potion
Red potion, also known as red mercury, is a disinfectant for external use, and should not be taken internally, as it contains toxic mercury.
When the eggs are boiled in red potion water, the mercury will pass through many small holes on the surface of the eggshell that are invisible to the naked eye, and then through a layer of film inside the eggshell, into the egg white and yolk, which will cause poisoning after eating. The eggs should be dyed red for the wedding ceremony, and should be red for consumption.

Eggs are eggs that hatch from chicks and are not released. Because of the temperature is not comfortable or infected with germs, the embryo in the egg died in the egg shell and stopped developing.
Some people think that this stillborn eggs have high nutritional value, and can cure a variety of diseases, in fact, there is no scientific basis.
Because this egg protein, fat, sugar, vitamins, inorganic salts and other nutrients have changed, the vast majority of the embryo use and consumption, the remaining nutrients are very little.
Determined that almost 100% of the stillborn eggs contain germs, such as Escherichia coli, staphylococcus, typhoid fever bacillus and methanotrophic bacillus, etc. These germs are harmful to human health.

The taboo of eating eggs for babies
Two "counts"
1 counts the amount of food
One or two years old children. The daily need for protein is about 40 grams, in addition to ordinary food, add 1 or 1 ? eggs per day is enough. The baby needs to eat egg yolks for iron supplementation, which can only be eaten by crushing 1/4 egg yolks at the beginning, and then gradually increased to 1/2-1. If you eat too much more than the child's needs, the child's stomach and intestines will not be able to afford, it will lead to digestion and absorption dysfunction, causing indigestion and malnutrition.
2 count the time to cook the eggs
The time to cook the eggs must be mastered, generally 8-10 minutes, cooked too raw, the anti-biotin protein in the egg can not be destroyed, so that the biotin inactivation, affecting the body's absorption of biotin, easy to cause biotin deficiency, tiredness, loss of appetite, muscle pain, and the occurrence of a few days.
Three "inappropriate"
1 half a year before the baby should not eat egg white
Because their digestive system is not well developed, the intestinal wall of the permeability is higher, egg white in the Albumin molecules are smaller, sometimes through the intestinal wall and directly into the baby's blood, so that the baby's body to the conductor protein molecules produce allergic phenomena, eczema, hives and other diseases.
2 should not eat fried eggs
Because in the fried eggs and fried eggs, the egg is wrapped in oil, high temperature oil can also make part of the protein scorched, so that the lysine and other amino acids are damaged, lose nutritional value, after eating will also be in the oral cavity and the stomach is not easy to contact and digestive fluids, so that digestion is affected.
3 feverish children should not eat eggs
Egg white after eating can produce "extra" heat, so that the body heat increase, is not conducive to the recovery of children.
Pre-school children should not eat half-boiled eggs
6-year-old children on the nutritional needs of the higher, only to eat a normal meal, often do not meet the needs of their physical development. Especially to eat some high-protein food, eggs are very nutritious, you can properly give the child to eat a little more. Some parents think that half-boiled eggs have a high nutritional value, which is the wrong view.
How to eat eggs for people of different ages

Eating eggs ten misunderstandings
Misunderstanding one: red shell eggs than white eggs have nutrition
In the past, people have always thought that the red shell eggs are more nutritious, the market price of red shell eggs is more expensive. Tests have shown that the color of the eggshell is related to the breed of chicken, not nutrition.
Myth 2: Farm eggs are more nutritious
Real farm eggs may taste better. However, tests have shown that the nutrient content of farm eggs is not higher than that of ordinary eggs. In addition, the hygiene of the laying environment of free-range chickens is not well controlled, and eggs are more likely to be contaminated by feces.
Myth 3: "Eggs" and "Functional Eggs" are more nutritious
Generally speaking, the eggs laid by chickens in the growing period of 130~160 days will be called "Eggs", and the eggs laid by chickens in the growing period of 130~160 days will be called "Eggs". The first is the first time I've ever seen an egg in my life. There is no test evidence that a newborn egg contains more nutrients than a regular egg. In fact, first eggs are small, about 40 grams each, and are not allowed to be sold abroad because they do not weigh enough to be standardized. Functional eggs are eggs enriched with nutrients such as zinc, iodine, selenium and calcium through feed technology. This sounds good, but in reality, because there is no standard and not good testing, many products have over publicized suspicion.
Myth 4: The more yellow the yolk, the better the nutrition
The color of the egg yolk is related to the various pigments it contains, some of which, such as carotene, do have nutritional value. However, the existing technical means can easily make the yolk color deeper, not only with the nutritional irrelevant, but also bring safety hazards.
Myth 5: Hairy eggs are a tonic
Hairy eggs are "stillborn eggs", which are embryos halfway through hatching, and are often consumed as a tonic in many areas. In fact, the hairy egg is not high in nutritional value, and often contains a lot of pathogenic bacteria.
Myth 6: The longer you cook an egg, the better
The best state to eat eggs is that the egg white is already solidified, and the yolk is in the state of semi-coagulation or flow. This ensures digestibility and absorption and avoids nutrient loss.
Myth 7: Raw eggs are more nutritious
Raw eggs interfere with the absorption of biotin (a B vitamin), and although occasional raw eggs do not lead to a biotin deficiency, they are susceptible to bacterial infection.
Myth 8: Mothers should eat more eggs
Mothers eat a lot of eggs when sitting on the moon is a custom in China, but in the rich food today, it is no longer applicable. Maternity should ensure food diversity, in addition to eating one or two eggs a day, but also meat, dairy, beans, grains and fruits and vegetables, in order to achieve a balanced diet.
Myth 9: Eggs should not be eaten with soy milk
Advocates of this argument that soybeans contain trypsin inhibitors, which affects the digestion and absorption of protein in the body. However, when soybeans are made into soymilk, the trypsin inhibitors are destroyed during the heating process and there is no problem with eating them with eggs.
Myth 10: You can't eat eggs when you have a cold
When you have a cold and a fever, the body's energy consumption is greater, the resistance will decline, and you can't eat anything, lack of nutrients, appropriate supplementation of eggs and other protein higher food, the recovery of the body is good. However, egg soup, egg flower soup is preferred, and fried eggs or fried eggs are not easy to digest.

Scrambled eggs are made by beating the eggs in a bowl and stirring them with chopped scallions and salt. Pour the oil into the wok and heat it up, then pour the beaten egg mixture into the wok and stir fry.
Omelette practice is to heat the pan, the pan smoke, pour a spoonful of oil, slightly hot, then knock down the eggs, frying slowly over low heat, according to personal preference until half cooked, or fully cooked, or both sides of the golden, and finally add the sauce seasoning can be.
Eggs are rich in nutrients that can sustain the body's nutritional needs, and are an essential source of home-cooked nutrition. Eggs are rich in high-quality protein, cholesterol and fat, as well as a variety of vitamins including vitamin A, vitamin B, vitamin D and vitamin E, as well as calcium, phosphorus, potassium, sodium and other minerals, has a more comprehensive and balanced nutrients, can meet different people at different stages of the different nutritional requirements.
