Scientific diet view eggs can not be placed horizontally
The high nutritional value of eggs is an essential diet for residents in their daily lives.
However, too many people have misunderstandings about eating eggs. In recent years, nutritionists have put forward some new ideas about scientific egg eating, which has a certain guiding role for residents to correctly eat eggs.
1 egg can not be stored horizontally: the protein of fresh egg is thick, which can effectively fix the egg yolk in the center of the protein.
After storage for a long time, especially when the external temperature is high, the protein mucus will slowly remove some water under the action of protease and lose the function of fixing the egg yolk.
At this time, if the egg is placed horizontally, since the yolk is smaller than the protein, the yolk will rise, close to the eggshell, and become a sticky egg.
Therefore, eggs should not be stored horizontally.
Eggs can not be placed horizontally to save the tips of the egg.
The eggs you buy must be stored in the refrigerator.
When you put it, you should put your head up and the head down, so that the egg yolk can be floated and placed under the air chamber, which can prevent microbes from invading the egg yolk and help to ensure the quality of the egg.
Eggs are not equivalent to volatile substances.
Therefore, the strong smell of substances such as onions, ginger, and peppers will penetrate into the eggs through the pores on the eggshell, accelerating the deterioration of the eggs.
Fresh eggs taken out of the refrigerator should be consumed as soon as possible, and should not be placed for a long time or refrigerated.
Because the eggs will “sweating” at room temperature after taking them, the bacteria and microorganisms in the small water droplets will quickly penetrate the eggshell and penetrate into the inner layer of the egg liquid, so the eggs are not preserved and should be consumed immediately.
Do not rinse with water before storing.
Some eggs have a dirty outer shell, and people like to store them after washing to avoid contaminating other foods.
However, the cleaning will destroy the outer eggshell membrane of the egg itself, so that bacteria and microorganisms can flow into the egg and accelerate the deterioration of the egg.
It can be wrapped in a fresh-keeping bag or film and placed without causing pollution.
Separate storage space When unconditionally refrigerating eggs, try to use a clean paper or cloth in the shape of an egg so that each egg has a separate storage space and avoid direct exposure to the air.
This reduces the chance of bacterial and microbial infestation and extends egg storage time.
2 middle-aged and elderly people do not have to be afraid of eating egg yolk: the traditional view that egg yolk contains high cholesterol, is the chief culprit directly leading to human hypertension, atherosclerosis, coronary heart disease and stroke.
Therefore, many people, especially middle-aged and elderly people, dare not eat egg yolk.
Dr. Flynn, an American nutritionist, recently organized a team dedicated to eggs and diabetes, and conducted a six-month trial of 116 men aged 50 to 65.
They first record the cholesterol content of each body weight, and then let these people eat the diet without any eggs for 3 months, then measure their cholesterol levels, and in the next 3 months, give each person daily intake.Add two eggs to the volume.
After 90 days passed, another measurement was made. As a result, the cholesterol content in the body itself was not affected by lecithin.
The results of this experiment have attracted the attention of the world medical community.
Considering that eggs contain a lot of protein, trace, vitamin A, B2, B6, D, iron, calcium, phosphorus and other nutrients, experts believe that eating 1 or 2 eggs per day (including egg yolk) is good for health every year.Not too much to eat.
Analysis of egg yolk nutrition: all the protein of egg yolk: People think that the protein in eggs is concentrated in the protein. In fact, the protein content of egg white is only about 11%, and the water content is as much as 88%.
The aunt, also concentrated in the egg yolk part, the egg white’s uncle content is only 0.
The aunts in the egg yolk are mainly monounsaturated fatty acids, and more than half of them are the main oil in the olive oil, oleic acid, which is good for preventing diseases.
Various vitamins in egg yolk: There are valuable vitamin A and vitamin D in egg yolk, as well as vitamin E and vitamin K.
These are all “fat-soluble vitamins” and there are no traces of these in the egg whites.
Even the dialysis of the vitamin B family, it also exists in the egg yolk.
Traces of various trace elements in egg yolk: There is a lot of phosphorus in the egg yolk, and there is too much iron.
Although the iron absorption rate in egg yolk is relatively low, it still plays an important role for infants who cannot eat meat.
At the same time, all lecithin in the egg comes from the egg yolk, and lecithin can provide choline to help synthesize an important neurotransmitter, acetylcholine.
Therefore, the first kind of complementary food for babies is often egg yolk.
Egg yolk is good for your child’s iron supplement and good for your child’s brain development.
3 Wang eggs (hair eggs) should not be eaten: Wang eggs are eggs that hatch chickens.
Due to temperature discomfort or infection, the egg remains dead in the eggshell and stops developing.
Some people think that this kind of dead fetus has high nutritional value and can cure a variety of diseases. In fact, there is no scientific basis.
Because the protein, traces, sugars, vitamins, inorganic salts and other nutrients in this egg have changed, most of them are consumed and consumed, and the remaining nutrients are minimal.
It has been determined that almost 100% of dead fetus eggs contain pathogens such as Escherichia coli, Staphylococcus, Salmonella typhi, Proteus and the like.
These germs are harmful to the human body.
Eating such eggs may cause food poisoning, dysentery, typhoid, hepatitis and other diseases.
4 Partial water poultry eggs to make cakes: When waterfowls float in the water, Salmonella in the river ponds will enter the leaking cavity through the anus at any time. The cloaca is the best place for microbial growth and reproduction.
In the exhaust chamber, Salmonella will move along the spawning path to the ovary, and the ovary will inevitably be infected with Salmonella from various stages of secreting egg yolk, egg white, and eggshell.
Therefore, if water eggs are used as cake ingredients, people will be poisoned by Salmonella infection, but headaches, nausea, vomiting, abdominal pain, diarrhea, and convulsions.
5 eggs local red syrup dyed red: the conventional folk useful red syrup to dye the eggs red to show the custom of the celebration.
Red syrup, also known as red mercury, is a topical disinfectant and should not be taken internally because it contains toxic mercury.
When boiled eggs are red boiled, mercury will penetrate many small holes that are invisible to the naked eye, and then pass through a film in the eggshell to enter the protein and egg yolk. After eating, people will cause poisoning.
Red flowers should be added when the eggs are dyed red.
