Eggs are common food in our lives, not the correct way of eating for our health has adverse effects. In life, we should note the following errors.
Misunderstanding one: the darker the shell, the higher the nutritional value
Many people choose to buy eggs only red shell, red shell eggs that are of high nutritional value, but it is not. The eggshell color is called by the "egg shell porphyrin" material decisions, and this material has not nutritional value. Analysis showed that the nutritional value of eggs, chicken nutrition depends on the level of the structure.
Evaluation of protein quality, mainly protein (egg white) in the protein content. From the sensory point of view, the more thick egg white, indicating that the higher protein content, protein quality, the better.
Egg yolk color depth with a light, from pale yellow to orange yellow have. Color of the pigment with egg yolk contains about. The main pigment in egg yolk lutein, zeaxanthin, lutein, carotene and riboflavin. Yolk color depth is usually only show the amount of pigment content. Some pigments such as lutein, carotene, etc. in the body into vitamin A, therefore, under normal circumstances, the deeper the color of egg yolk slightly better nutrition.
Misunderstanding of the two: how to eat nutritious eggs are the same
Eggs eaten are diverse, there are boiled, steamed, fried, fried and so on. To eggs in terms of nutrient absorption and digestibility, cooking, egg is 100%, 98% tender fried, scrambled eggs and 97%, egg 92.5%, 81.1% of the old deep-fried, eaten raw, 30% to 50% . Seen in this light, boiling, steaming should be the best way to eat eggs.
Misunderstanding number three: fried eggs, MSG taste will be better
Egg itself contains a large number of glutamate and a certain amount of chloride, sodium, heating the two substances will generate a new material - sodium glutamate, which is the main component of MSG, there are pure flavor . If the scrambled eggs when the MSG, MSG would destroy the flavor decomposition of the natural flavor of the egg itself. Therefore, when the scrambled eggs should not be put MSG.
Misunderstanding of the four: the longer the better boiled egg
To prevent the eggs in the shell burst in the cooking, the egg wash, put a water pot and soak for 1 minute over low heat to boil. After the switch to open Simmer 8 minutes. Avoid cooking too long, otherwise the egg yolk with ferrous ions in the chemical reaction of sulfide ions to form ferrous sulfide precipitate brown, hinder the body's absorption of iron.
Eggs cooked for too long, egg yolk proteins in ferrous iron and sulfide ions combine to form insoluble iron sulfide, it is difficult to be absorbed. Fried eggs over the old, the edge will be burnt, contains egg proteins into low molecular weight polymer of amino acids, this amino acid can be formed at high temperatures often detrimental to human health of chemical substances.
Misunderstanding Five: fresh eggs and milk with high nutritional
The morning to drink milk when eating eggs, or the egg in milk and cook, many people's eating habits. Level of sweet milk, with vegetable protein, fat, carbohydrates, vitamins, minerals, and many other nutrients, have a good drinking alone tonic. However, there is a special substance called trypsin, and the egg white ovalbumin in combination, can cause the loss of nutrients, reducing the nutritional value of the two.
Misunderstanding Six: "functional egg" better than ordinary eggs
As science and technology. Rich in zinc, iodine, selenium, calcium and other "features eggs" come out. In fact, not all people are suitable for food feature eggs. Because not everyone is missing the nutrients contained in the egg function. Therefore, the function of eggs in the choice of consumers should be targeted, what to eat anything missing, should not blind tonic.
The Seven Mistakes: the elderly Jichi eggs
Because eggs contain high cholesterol, it has been popular with elderly people not eat the egg argument. Recent scientific evidence shows that this argument does not make sense.
Rich egg yolk contains lecithin, is a powerful emulsifier, cholesterol and fat particles can become very fine, smooth cells through the blood vessel wall has been fully utilized, thereby reducing blood cholesterol. And egg yolk lecithin is choline released after digestion, into the blood in the synthesis of acetylcholine and thus is the main neurotransmitter substances, can improve brain function, enhance memory.
Misunderstanding of the eight: eat eggs better maternal
Mothers during childbirth physical exertion, digestion and absorption function, and liver detoxification function to reduce a large number of food will cause liver and kidney burden, causing adverse consequences. Ingestion of too much protein, but also in the intestine produce large amounts of ammonia, phenol and other chemicals toxic to the body's large, easy to abdominal swelling, nausea, dizziness, limb weakness, coma and other symptoms, resulting in "Protein synthesis poisoning levy. " Protein intake should be based on the body of the protein digestion and absorption calculation. Under normal circumstances, maternal eat three or so eggs would be sufficient.
Nine Mistakes: raw eggs are more nutritious
Some people think that raw eggs are nourishing the lungs and vocal effects. In fact, the raw egg is not only unsanitary, likely caused by bacterial infection, but not more nutritious. Raw eggs contains avidin, biotin affect the absorption of food, easy to make the body loss of appetite, general weakness, muscle pain, skin inflammation, eyebrow, etc. "biotin deficiency." Raw egg protein structure is dense, and contain anti-trypsin, that the great majority can not be absorbed by the body, and only cooked the protein only become soft, it is more beneficial to human digestion and absorption.
In addition, there is the smell of raw eggs, can cause central nervous system depression, the saliva, gastric and intestinal fluid and so reduce the secretion of digestive juices, leading to loss of appetite, indigestion. Therefore, eggs should be cooked at high temperature before eating, do not eat the immature eggs.
Ten Mistakes: cook eggs and sugar
Many places to eat sugar egg habit. In fact, the eggs and sugar, cook, make the egg protein in the formation of fructose lysine amino acid conjugates. This substance can not easily be absorbed by the body, would cause adverse health effects.
