What is the nutritional value and consumption of eggs, eggs are very nutritious food, is almost every day people eat a kind of ingredients, it is rich in cholesterol, a large number of proteins and a variety of vitamins and amino acids, nutritious, in order to come down to understand the nutritional value of the eggs and consumption of efficacy is what?

What is the nutritional value of eggs and edible efficacy 1

Nutritional value of eggs and edible efficacy

1, to protect the liver

Eggs in the protein on the liver tissue damage has a role in repairing the yolk in the lecithin can promote the regeneration of liver cells. It can also increase the amount of plasma protein in the human body, enhance the metabolic function of the body and immune function.

2, tonic body

In addition to protein, eggs have a high content of calcium, phosphorus, iron and vitamins. Therefore, eggs are the ideal food for the growth and development of children and adolescents, and are a good tonic food for pregnant women and weak, anemic people.

3, brain

The egg yolk is rich in lecithin, sterols, 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, therefore, the egg is a better brain food. Rich in DHA and lecithin, lecithin, on the nervous system and physical development is favorable, can be brain-healthy, improve memory .

4, blood beauty

Eggs are also rich in iron, iron in the human body plays a role in hematopoietic and transportation of oxygen and nutrients in the blood. People's faces are full of the beauty of the red, can not do without iron. If the iron is not enough can lead to iron deficiency anemia, so that people's face yellow, the skin has lost the luster of the United States. This shows that the egg is indeed one of the important food to maintain the beauty of the skin.

5, the nutritional composition of eggs

The nutritional composition of eggs is more comprehensive, egg white is rich in high-quality protein, riboflavin, niacin, biotin and calcium, phosphorus, iron and other substances; and yolks are rich in lecithin, vitamin A, vitamin D, and contains more iron, phosphorus, sulfur, calcium.

Above is the health online I give you a detailed introduction to the nutritional value of eggs and edible efficacy, we should have a heart, eggs are not only blood beauty, but also brain, we can usually choose to eat eggs to enhance physical fitness.

Nutritional value of eggs

Egg yolk in the lecithin, triglycerides, cholesterol and yolk pigment, on the nervous system and physical development has an important role, can slow down the decline of the elderly intelligence. Lecithin is regarded by medical experts as the nemesis of Alzheimer's disease, but also to prevent atherosclerosis. Protein in eggs has a repair effect on liver tissue damage. Eating eggs in moderation is one of the experiences of many long-lived people to prolong life.

Eggs eat a variety of ways, on the absorption of nutrients and digestibility, hard-boiled eggs for 100%, scrambled eggs for 97%, 98% of the tender fried, the old fried for 81.1%, open water, milk, 92.5% of the eggs, eaten raw for 30% -50%. It can be seen that hard-boiled eggs are the best way to eat, but be careful to chew and swallow slowly, otherwise it will affect the absorption and digestion. However, for children and the elderly, or steamed egg custard, egg soup is the most suitable, because these two practices can make the protein slack, very easy to be digested and absorbed. Eggs are not high in vitamin C, so it is best to eat eggs supplemented with a moderate amount of vegetables.

From a nutritional point of view, in order to ensure a balanced diet, to meet the needs of the body, but not over-nutrition, in general, the elderly eat 1 egg a day is appropriate. Young people, engaged in mental labor or light manual labor, you can eat two eggs a day;

Engaged in heavy physical labor, consume more nutrients, you can eat two eggs a day; children and adolescents due to the growth of the body, the metabolism is fast, you can also eat two eggs a day. Pregnant women, women in labor, frail people and patients recovering from major surgery, need to increase the good protein, you can eat 2 - 3 eggs a day, should not be too much.

How to cook eggs

1. Method.

Boiled eggs seem simple, but very learned. If the cooking method is not appropriate, it will destroy the nutrients of the egg.

Wash fresh eggs, put them in a pot of water to soak for a minute, and then boil them on low heat. This is to prevent the shell from cracking during the boiling process.

2. Fire.

Boiled eggs if the fire, easy to cause rapid expansion of the air inside the shell and lead to shell cracking; if the use of small fire, and prolonged the time to cook the eggs, and it is not easy to grasp the degree of good eggs old and tender. Practice has shown that cooking eggs in the fire is most suitable.

3, time.

After determining the size of the fire, as long as an accurate grasp of the time to cook eggs, you can control the degree of tenderness of the egg at will. For example, soft boiled eggs, boiling water can be cooked for 3 minutes. At this time, the egg white solidified, the yolk is still fluid; cook loose eggs, boil the water and cook for 5 minutes. At this time, the egg white solidified, the yolk was thick liquid, soft and smooth; hard-boiled eggs, boil the water and cook for 7 minutes. At this time, the egg white solidified, the yolk is dry. It should be noted that hard-boiled eggs do not extend the time at will. Because the eggs in the boiling water cooking time is too long, more than 10 minutes, the eggs will be a series of internal chemical changes, thus reducing the nutritional value of eggs.

4, in the process of cooking, in order to make the egg yolk solidified in the middle of the egg white, should be in the egg in the pot with a hand spoon constantly stirring in one direction, so that the water in the pot was swirling, until cooked. As for what principle this is, it must have something to do with centrifugal force and centripetal force in physics

If an egg is cooked in boiling water for more than 10 minutes, a series of chemical changes will occur inside. The protein structure becomes tighter and less likely to come into contact with the protein-digesting enzymes in the gastric juices, so it's harder to digest. Egg protein contains more methionine, after a long period of heating, it will break down the sulfide, it reacts with the iron in the yolk, the formation of the year the human body is not easy to absorb iron sulfide, more nutritional losses.

Misunderstanding of eating eggs

Misunderstanding one: the darker the color of the eggshell, the higher the nutritional value

Many people buy eggs and only pick the red shell, that is, the red shell of the egg nutritional value is high, and the fact is not so. The color of the eggshell is mainly by a kind of called? The color of the eggshell is mainly caused by a substance called "eggshell porphyrin". The color of the eggshell is mainly determined by a substance called porphyrin, which has no nutritional value. The nutritional value of an egg depends on the nutritional structure of the chicken's diet.

Evaluation of the quality of the egg white, mainly the protein content of the egg white (egg white). Organoleptically, the thicker the egg white, the higher the protein content, the better the quality of the egg white.

The color of the yolk can be dark or light, from pale yellow to orange. The color of the yolk is related to the pigments it contains. The main pigments in the yolk are lutein, zeaxanthin, luteinizing hormone, carotene and riboflavin. The color of the yolk usually indicates only the amount of pigment. Some pigments such as lutein, carotene, etc. can be converted into vitamin A in the body, therefore, under normal circumstances, the yolk color darker eggs slightly better.

Myth two: how to eat eggs nutrition are the same

Eggs eat a variety of ways, there are boiled, steamed, fried, scrambled and so on. In terms of the absorption of egg nutrients and digestibility, boiled, steamed eggs for 100%, tender fried for 98%, scrambled eggs for 97%, eggs for 92.5%, the old fried for 81.1%, eaten raw for 30% to 50%. From this point of view, boiled, steamed eggs should be the best way to eat.

Misunderstanding of the third: the longer the better to cook eggs

In order to prevent the eggs in the boiling eggshell cracking, the eggs will be washed, placed in a pot of water to soak for 1 minute, with a small fire to boil. After the opening of the fire to cook 8 minutes can be. Do not boil too long, otherwise, the yolk of the ferrous ions and sulfur ions will produce a chemical reaction, the formation of ferrous sulfide brown precipitate, hindering the body's absorption of iron.

Eggs boiled too long, the yolk of the ferrous ion and the protein in the sulfur ion chemically generated insoluble ferrous sulfide, it is difficult to be absorbed. Frying eggs too old, the edge will be scorched, the high molecular protein contained in the egg white will become low molecular amino acids, this amino acid in the high temperature can often be formed on the human health of the adverse chemical substances.

Finally, we remind you that raw eggs have a special fishy flavor, but also cause central nervous system inhibition, so that saliva, gastric and intestinal fluids and other digestive juices to reduce the secretion, which leads to loss of appetite, indigestion. Therefore, eggs should be cooked by high temperature before eating, do not eat uncooked eggs.

What are the contraindications to eating eggs

1, add sugar, add soybean milk to eat

Similarly, eggs can not be eaten with soybean milk. We know that every day as a mom will carefully prepare breakfast for the child, hoping that the child can get enough nutrition in the early morning. That's why many moms will beat the egg flower in the soy milk. Or let their children quench their thirst with soymilk after they finish eating eggs. In fact, drinking alone has a strong nourishing effect of soybean milk contains a special substance called trypsin, which is combined with egg white in the ovalbumin, will cause the loss of nutrients, reduce the nutritional value of the two.

2, eat raw

If you think that raw eggs are better nutrition, you are very wrong! It is understood that the nutritional value of hard-boiled eggs is higher than fried eggs, and fried eggs are higher than fried eggs, raw eggs.

And uncooked eggs contain a lot of E. coli, into the esophagus can easily cause diarrhea. Therefore, eggs should be cooked at high temperatures to kill the bacteria before eating. Plus raw eggs contain anti-biotin protein, which affects the absorption of biotin in food, leading to loss of appetite, general weakness, muscle pain, etc. ? Biotin deficiency? There is also antitrypsin, which can disrupt the body's digestive function. One more thing to keep in mind is to beware of bacteria that get on the eggshells when you beat the eggs!

3, eat overnight

Eggs can be reheated and eaten the next day if they are fully cooked. However, half-boiled eggs, eaten overnight but not! If the egg is not fully cooked, it is easy to breed bacteria in the case of improper preservation, resulting in gastrointestinal discomfort, flatulence and so on. Some people think that the longer the eggs are cooked, the better, which is also wrong. This is also wrong, because if the eggs are cooked for too long, the ferrous ions in the yolk will combine with the sulfur ions in the egg white to form insoluble ferrous sulfide, which is difficult to be absorbed. When frying eggs, pay special attention to the edge not to be scorched, because the high molecular protein contained in the egg white will become low molecular amino acids, this amino acid in the high temperature can often be formed on the human health of the chemical substances.

4, soak in cold water to eat

I believe that many people have done this, that is, in the boiled egg when the egg is placed in cold water over water, the use of egg white and eggshell expansion degree of different, is its separation, but it will become good peeling. The original fresh egg surface has a layer of protection

membrane, is to make the egg water is not easy to evaporate, to prevent the invasion of microorganisms, but cooked this layer of protection film has been destroyed. When the egg is put into cold water, the cold water and microorganisms can cross the bridge holes in the egg shell and the double membrane inside the shell to enter the egg. When you eat it, you will eat the bacteria as well.

5, eat too much

Although the nutritional value of eggs is high, but eggs are not eaten the more the better. Eating too much egg is easy to cause nutritional overload, leading to obesity. Increase the burden on the liver and kidneys. And protein excess will make the urea manufacturing system overload, eating too much protein, but also in the intestinal tract to produce a large number of ammonia, hydroxyl, phenol and other chemicals, the human body is very toxic. It is likely to be prone to abdominal distension and stuffiness, dizziness, weakness of the limbs, coma and other symptoms, which is often referred to as ? Protein toxicity syndrome?

6, eat on an empty stomach

Eggs eaten on an empty stomach affects gastrointestinal health. Especially when you wake up in the morning, you have to eat something else first to fill up your stomach, preferably starchy and cereal. Then replenish the protein, which is conducive to the absorption of amino acids. In general, eating eggs on an empty stomach, the protein in them will be directly broken down into sugar to supply the energy needed by the body, making the protein not absorbed by the body.
