1. Brain-strengthening and intelligence-improving: Eggs have great effects on the nervous system and physical development, and choline contained in them can improve the memory of all ages.

2. Protect the liver: protein in eggs can repair liver tissue damage, and lecithin in egg yolk can promote liver cell regeneration. It can also increase the amount of human plasma protein and enhance the body's metabolic function and immune function.

3. Prevention and treatment of atherosclerosis: American nutritionists and medical workers used eggs to prevent and treat atherosclerosis and achieved amazing results. They extract lecithin from eggs, walnuts and pig liver and give it to patients with cardiovascular diseases 4 ~ 6 tablespoons a day. After 3 months, the patient's serum cholesterol decreased obviously and achieved satisfactory results.

4. Cancer prevention: According to the analysis of human cancer mortality in the world, it is found that cancer mortality is inversely proportional to selenium intake. Eggs are rich in selenium.

5. Anti-aging: One of the longevity experiences of many elderly people is to eat an egg every day.

6. Beauty and skin care: Eggs are also rich in iron, which plays a role in hematopoiesis and transporting oxygen and nutrients in blood. The ruddy beauty of human face is inseparable from iron. If iron deficiency can lead to iron deficiency anemia, people's face will turn yellow and their skin will lose its beautiful luster. It can be seen that eggs are indeed one of the important foods to maintain skin beauty.

Taboos for eating eggs

1, don't eat sugar immediately after eating eggs.

Eggs can't be cooked with monosodium glutamate, which I believe many housewives already know. But you may not know that eggs can't be boiled with sugar or eaten with sugar. Many places have the habit of eating poached eggs in sugar water. In fact, it can make amino acids in egg protein form a combination of fructosyl lysine. This substance is not easily absorbed by the human body, so it will have a bad influence on health.

Don't eat persimmon immediately after eating eggs.

Eating persimmon after eating eggs will lead to food poisoning, which will always lead to acute gastroenteritis and lung stones. Generally speaking, eating these two foods at the same time will lead to acute gastroenteritis symptoms such as vomiting, diarrhea and abdominal pain. So if you take it within 1-2 hours, you can use the method of inducing vomiting. Immediately take 20g of salt and add 200ml of boiling water to dissolve it, and drink it once after cooling. If you don't vomit, you can drink more times to quickly promote vomiting. Or you can mash fresh ginger to get juice and take it with warm water. If you take it for a long time, take some laxatives as soon as possible to discharge toxic substances.

Don't drink soybean milk immediately after eating eggs.

Every morning, mothers will carefully prepare breakfast for their children. I hope children can get enough nutrition in the morning. So many mothers put frangipani in soybean milk. Or let the children quench their thirst with soy milk after eating eggs. In fact, drinking soybean milk alone has a strong nourishing effect and contains a special substance called pancreatic protein? When it is combined with ovalbumin in egg white, it will cause the loss of nutrients and reduce the nutritional value of both.

Don't eat goose or rabbit immediately after eating eggs.

Eggs can't be eaten with meat such as rabbit and goose. Li Shizhen said in Compendium of Materia Medica: "Eggs and rabbit meat can cause diarrhea." That's because rabbit meat tastes sweet and cold, while eggs taste sweet and flat and slightly cold. Both of them contain some bioactive substances, which will react when eaten together, stimulate the gastrointestinal tract and cause diarrhea.

Don't eat turtle meat immediately after eating eggs.

Eggs also have many taboos, because they are rarely used to match and are little known. For example, eating turtle meat after eating eggs can also lead to food poisoning. Carp itself is greasy, and people who have a cold or are cold and wet generally don't eat it. In addition, it is salty and flat, so pregnant women and people with poor digestive system who have just given birth to BB can't eat it.

The taboo of eating eggs for the elderly.

Eggs are boiled with sugar.

Many places have the habit of eating poached eggs in sugar water. In fact, when eggs are cooked with sugar, amino acids in the protein of eggs will form fructosyl lysine conjugates. This substance is not easily absorbed by the human body and will have a negative impact on health.

Eat eggs and soy milk together.

Eating an egg when drinking soybean milk in the morning, or boiling the egg in soybean milk, is the eating habit of many people. Soybean milk is sweet in taste and rich in nutrients, so it has a strong nourishing effect when drunk alone. However, there is a special substance called trypsin, which, when combined with ovalbumin in egg white, will cause the loss of nutrients and reduce its nutritional value.

Eat eggs with rabbit meat.

Eggs cannot be eaten with rabbit meat. Eating eggs with rabbit meat will stimulate the gastrointestinal tract and cause diarrhea.

Eggs are stored horizontally.

The protein of fresh eggs is thicker, which can effectively fix the yolk in the center of protein.

When stored for a long time, especially when the outside temperature is high, the protein mucus will slowly remove some water under the action of protease and lose the function of fixing egg yolk.

At this time, if the egg is placed horizontally, because the specific gravity of the yolk is less than that of the protein, the yolk will float up and cling to the eggshell, becoming a sticky egg. Therefore, eggs should not be placed horizontally.

Eggs are dyed red by mercuric chloride.

Mercuric chloride, also known as mercuric chloride, is a disinfectant for external use and cannot be taken orally because it contains toxic mercury.

When boiled eggs with red medicine, mercury will pass through many invisible holes on the surface of the eggshell, and then pass through a layer of thin film inside the eggshell, and enter protein and yolk, which will cause poisoning after people eat it. When eggs must be dyed red at the wedding, edible red should be used.

Eat the king's eggs

A prosperous egg is an egg that hatches chicks and never comes out. Because of temperature discomfort or infection with germs, the embryo in the egg dies in the eggshell and stops developing.

Some people think that this kind of stillborn egg has high nutritional value and can cure many diseases. There is actually no scientific basis.

Because protein, fat, sugar, vitamins, inorganic salts and other nutrients in this egg have changed, most of them are used and consumed by embryos, and there are few nutrients left.

According to the determination, almost 100% of stillborn eggs contain germs, such as Escherichia coli, staphylococcus, typhoid Bacillus, Proteus and so on. These bacteria are harmful to human body. Eating this kind of egg may cause food poisoning, dysentery, typhoid fever, hepatitis and other diseases.

Taboos for women to eat eggs

First, women can't eat eggs every day.

Women who eat/kloc-0 eggs or more a day have a higher mortality rate than women who eat only one or two eggs a week. Women who eat the most eggs are also more likely to die of heart disease and stroke, although statistically speaking, the relationship between them is not very close. Scholars believe that this may also be related to the fact that women rarely die from these two diseases.

2. Under normal circumstances, healthy adults eat 1-2 eggs a day; It is best for the elderly to eat one every day; It is more appropriate for mental workers to eat two eggs a day; Pregnant women, lying-in women, lactating women and the infirm can eat 2-3 eggs a day, not more. Boiled eggs are the best way to eat, but you can't overcook them.

If you want to eat eggs every day, try not to eat yolk.

Eggs are high-protein foods. If you eat too much, it will lead to an increase in metabolites and increase the burden on the kidneys. Generally speaking, healthy adults should pay close attention to and control the cholesterol intake through other ways such as meat and dairy products, eat 1 egg every day, and try not to eat egg yolk, because an egg yolk contains two-thirds of the cholesterol that healthy adults should consume every day.

Second, the top ten precautions for women to eat eggs

1, teach you how to pick eggs.

Hold the eggs in your hand, gently shake them to collide with each other, and listen carefully; Or shake it in your hand and listen to its sound. Fresh meatballs and eggs collide with each other and make a crisp sound, and the eggs are silently shaken.

2, boiled eggs: the most nutritious but not overcooked.

In cooking, boiled eggs are the best way for adults to eat, but they should not be overcooked. It is advisable to cook eggs in boiling water for 5~7 minutes, but pay attention to chewing slowly, otherwise it will affect absorption and digestion.

3. Eat less tea eggs

When fried eggs are over-aged, the edges will burn, and the high molecular weight protein contained in egg white will become low molecular weight amino acids, which can often form toxic chemicals at high temperature. In addition, it should be noted that tea eggs should be eaten less, because tea contains acidified substances, which combine with iron in eggs to stimulate the stomach and affect the digestive function of the gastrointestinal tract.

Don't drink soybean milk immediately after eating eggs.

Every morning, mothers will carefully prepare breakfast for their children. I hope children can get enough nutrition in the morning. So many mothers put frangipani in soybean milk. Or let the children quench their thirst with soy milk after eating eggs.

6. Don't take anti-inflammatory drugs immediately after eating eggs.

Eggs are rich in protein, so pay special attention to the intake of protein when inflammation occurs. So when inflammation breaks out, remember not to take medicine after eating eggs. Especially for digestive tract diseases, people with diarrhea symptoms should not eat eggs. Because eggs contain a lot of protein, it will increase the burden of gastrointestinal tract and have an impact on drug efficacy, especially for fatty diarrhea.

7. Don't drink tea immediately after eating eggs.

Many people like to use tea to relieve boredom after eating eggs. Especially those who like to drink morning tea to refresh themselves. But at this time, in fact, you ignore that drinking tea after eating eggs will be harmful to your health. Because tea contains a lot of tannic acid, tannic acid and protein synthesize convergent protein tannic acid, which slows down intestinal peristalsis and prolongs the time of feces staying in the intestine, which not only easily causes constipation, but also increases the possibility of toxic substances and carcinogens being absorbed by the human body, which is harmful to human health.

8. Don't eat persimmons immediately after eating eggs.

Eating persimmon after eating eggs will lead to food poisoning, which will always lead to acute gastroenteritis and lung stones. Generally speaking, eating these two foods at the same time will lead to acute gastroenteritis symptoms such as vomiting, diarrhea and abdominal pain. So if you take it within 1-2 hours, you can use the method of inducing vomiting. Immediately take 20g of salt and add 200ml of boiling water to dissolve it, and drink it once after cooling.

Carp itself is greasy, and people who have a cold or are cold and wet generally don't eat it. In addition, it is salty and flat, so pregnant women and people with poor digestive system who have just given birth to BB can't eat it.

Baby's taboo to eat eggs

Two "calculations"

1 Calculate your appetite

A one-year-old or two-year-old child needs about 40 grams of protein every day. In addition to ordinary food, it is enough to add 1 or 1 half an egg every day. Babies need to eat egg yolk to supplement iron. At first, you can only grind 1/4 egg yolk, and then gradually increase it to 1/2- 1. If eating too much exceeds the child's needs, the child's gastrointestinal tract can't bear it, which will lead to digestive and absorption dysfunction, causing indigestion and malnutrition.

2 calculate the time to boil eggs

The time for boiling eggs must be well controlled, usually 8- 10 minutes. If the egg is boiled too raw, the avidin in the egg cannot be destroyed, which will make biotin inactive and affect the absorption of biotin by the body. It is easy to cause biotin deficiency, fatigue, loss of appetite, muscle pain, and even hair loss and dermatitis, which is not conducive to eliminating bacteria and parasites in eggs. It is not good to cook it too hard. Because it takes a long time to cook, the structure of protein becomes tight, and it is difficult to contact with gastric juice, so it is difficult to digest.

Three "not suitable"

/kloc-Babies before the age of 0 should not eat egg white.

Because their digestive system is underdeveloped, the permeability of intestinal wall is high, and the albumin molecules in egg white are small, sometimes they can directly enter the baby's blood through the intestinal wall, which makes the baby's body allergic to conductive protein molecules and causes eczema, urticaria and other diseases.

Don't eat fried eggs.

Because when frying eggs, the eggs are wrapped in oil, and the high-temperature oil can also scorch some protein, so that amino acids such as lysine are destroyed and lose their nutritional value. After eating, they are not easy to contact digestive juice in the mouth and stomach, which affects digestion.

Children with fever should not eat eggs.

After eating egg protein, it will produce "extra" calories, which will increase the calories in the body, which is not conducive to the rehabilitation of sick children.

Preschool children should not eat half-cooked eggs.

Children around the age of 6 have a high demand for nutrition, and eating normal meals alone often cannot meet the needs of physical development. In particular, eat some high-protein foods. Eggs are rich in nutrition, so you can give your children more food. Some parents think that half-cooked eggs have high nutritional value, which is wrong.

How do people of different ages eat eggs?

Infants aged 0 to/kloc-0 are suitable for eating steamed egg custard or egg drop soup, which can loosen protein and be easily digested and absorbed by children. You can eat boiled eggs after one or two years old, and scrambled eggs after two years old; Old people should try to eat fewer fried eggs. When steaming egg custard or scrambled eggs, you can also add some leeks, green peppers and shrimps to the beaten eggs according to your personal taste.

Ten misunderstandings about eating eggs

Myth 1: Red-shelled eggs are more nutritious than white-shelled eggs.

In the past, people always thought that red-shelled eggs were more nutritious, and the price of red-shelled eggs in the market was more expensive. The experiment shows that the color of eggshell is related to the variety of chicken and has nothing to do with nutrition.

Myth 2: Farm eggs are more nutritious.

Real farm eggs (earth eggs) may taste better. However, tests show that the nutritional content of farm eggs is not higher than that of ordinary eggs. In addition, the hygienic condition of the laying environment of free-range chickens is not easy to control, and eggs are more easily polluted by feces.

Myth 3: "Newborn eggs" and "functional eggs" are more nutritious.

Generally speaking, the eggs laid by chickens within 130~ 160 days during the growing period are called newborn eggs. There is no experimental evidence that newborn eggs have more nutrients than ordinary eggs. In fact, newborn eggs are very small, about 40 grams each, and are not allowed to be sold abroad because their weight is not up to standard. Functional eggs are rich in nutrients such as zinc, iodine, selenium and calcium through feed technology. This sounds good, but in fact, because there is no standard and it is not easy to detect, many products are suspected of over-promotion.

Myth 4: The yellower the yolk, the better the nutrition.

The color of egg yolk is related to many pigments, some of which, such as carotene, do have nutritional value. However, the existing technical means can easily deepen the color of egg yolk, which is not only irrelevant to nutrition, but also brings potential safety hazards.

Myth 5: Hairy eggs are tonics.

Hairy eggs, or "stillborn eggs", are embryos that hatch halfway and are often eaten as tonics in many areas. In fact, the nutritional value of hairy eggs is not high, and they often contain many pathogenic bacteria.

Myth 6: The longer the eggs are cooked, the better.

The best condition for eating eggs is that the egg white has solidified, while the yolk is in a semi-solidified or flowing state. This can not only ensure the digestion and absorption rate, but also avoid nutrient loss.

Myth 7: Eating eggs raw is more nutritious.

Eating raw eggs will interfere with the absorption of biotin, a B vitamin. Although eating raw eggs occasionally will not lead to biotin deficiency, eating raw eggs is easy to infect bacteria.

Myth 8: Mom should eat more eggs.

It is a custom for lying-in women to eat a lot of eggs when they are in confinement, but it is no longer applicable today when food is abundant. Maternal women should ensure the diversity of food, besides eating one or two eggs a day, they should also eat meat, milk, beans, grains, fruits and vegetables to achieve a balanced diet.

Myth 9: Don't eat eggs with soy milk.

Advocates believe that soybean contains trypsin inhibitor, which will affect the digestion and absorption of protein in the body. However, after soybean is made into soybean milk, trypsin inhibitor is destroyed during heating, so it is no problem to eat it with eggs.

Myth 10: You can't eat eggs if you have a cold.

When you have a cold and a fever, your body consumes a lot of energy, so your resistance will drop, you can't eat, and you lack nutrition. Supplementing the relatively high food in protein, such as eggs, is good for your health. But custard and egg drop soup are the first choice, while fried eggs or fried eggs are not easy to digest.

Nutritional value of eggs

1. Eggs are rich in protein, fat, vitamins and minerals needed by human body, such as iron, calcium and potassium. Protein is a high-quality protein, which can repair liver tissue damage;

2. It is rich in DHA, lecithin and yolk protein, which is beneficial to the development of nervous system and body, can strengthen brain and improve intelligence, improve memory and promote liver cell regeneration;

3. Eggs contain more trace elements such as vitamin B, which can decompose and oxidize carcinogens in the human body and have anti-cancer effects.

How to choose eggs

1 You can hold the egg in a circle with your left hand through sunlight transmission and put the egg at the end of the circle with your right hand. Fresh eggs are reddish and translucent under the sunlight, and the outline of yolk is clear. If the color is dark, opaque or stained, the egg has gone bad.

It can be observed that a layer of frost powder is attached to the eggshell, and the eggshell is brightly colored, and the pores are obviously fresh eggs. Old eggs are just the opposite, greasy.

Fresh eggs can be shaken silently by hand, and old eggs can hear the sound of water.

You can try it with cold water. If the egg lies flat in the water, it means it is very fresh. If it is tilted in water, it will be stored for at least 3~5 days; If it stands upright in water, it may be stored for 10 days. If it floats on the water, it may have gone bad. It is recommended not to buy it.

Seven tricks to distinguish true and false eggs

1. The color of fake egg eggshells is brighter than that of real eggs, but it is not obvious.

2. Touching fake egg eggshells with your hands will make you feel rougher than real eggs.

There will be noise when shaking fake eggs, because water overflows from the coagulant.

4, smell carefully with your nose, real eggs will have a faint fragrance.

5, tap, the real egg sounds crisp, and the fake egg sounds dull.

6. Soon after the fake egg is opened, the yolk and egg white will blend together. This is because egg yolk and egg white are made of homogeneous raw materials.

7. When you fry fake eggs, you will find that the yolk is naturally scattered, without stirring. This is because the film wrapped with artificial egg yolk is cracked by heat.

Introduction to the home-cooked practice of eggs

As a kind of nutritious food, eggs can be cooked, steamed, fried and fried in various ways.

The way to cook eggs is to put them in cold water, first cook them with high fire, then cook them slowly for four or five minutes with low fire, and then stew them with waste heat after the ceasefire.

The practice of steaming eggs is to knock the eggs into a bowl (usually 2 or 3 eggs in a bowl), add a proper amount of seasoning and warm water twice as much as the egg liquid, and stir well. Add enough water to the pot, bring to a boil, then put the eggs in the steamer, cover and steam for 10 to 15 minutes.

The method of scrambled eggs is to beat the eggs in a bowl, add chopped green onion, salt and other ingredients and mix well. Heat the oil in the pan, then pour the beaten egg juice into the pan and stir fry.

The way to fry eggs is to heat the pan. After the pot smokes, pour in a spoonful of oil. When it's a little hot, knock down the eggs, fry them slowly over low heat, and fry them until half-cooked, full-cooked or golden on both sides according to personal preference. Finally, add sauce to taste.

Eggs are rich in nutrients, which can maintain the nutritional needs of the human body and are an essential source of nutrition at home. Eggs are rich in high-quality protein, cholesterol and fat, as well as vitamins including vitamin A, vitamin B, vitamin D and vitamin E and minerals such as calcium, phosphorus, potassium and sodium. Their nutrition is comprehensive and balanced, which can meet the different nutritional needs of different people at different stages.
