Four seasons tonic

The nutritional value of eggs, I do not necessarily need to say more, we all know!!!! Egg protein amino acid ratio is very suitable for human physiological needs, easily absorbed by the body, the utilization rate of more than 98%, high nutritional value. The content of calcium, phosphorus, iron and vitamin A in eggs is very high. Vitamin B is also rich in vitamins. It also contains many other essential vitamins and trace elements.

Although the high nutritional value of eggs, eating varied, but there are still 5 major mistakes in eating eggs need attention.

Myth 1: the darker the eggshell color, the higher the nutritional value

Color and nutritive value of the egg shell does not matter much, analysis showed that the nutritional value of egg nutritional value depends on the egg, the feeding situation depends mainly on the feed nutrition structure and chicken, there is no relation between eggshell color. From the sensory point of view, the thicker the egg white, the higher the protein content, the better the quality of the protein. Under normal circumstances, the egg yolk color of the eggs are slightly better nutrition.

Misunderstanding two: how to eat eggs, nutrition is the same

Eggs are eaten in a variety of ways, including cooking, steaming, frying, frying, etc.. On the digestion and absorption of nutrition egg rate, boiled, steamed egg 100%, tender fried 98%, egg 97%, Poached Egg 92.5%, old fried 81.1%, raw was 30% ~ 50%. From this point of view, cooking and steaming eggs should be the best way to eat.

Misunderstanding three: eggs and soybean milk with high nutrition

Soy milk flavor, containing vegetable protein, fat, carbohydrates, vitamins, minerals and many other nutrients, drink alone, there is a good tonic role. Soybean Milk contains trypsin inhibitor, can inhibit the activity of human protease, affect the digestion and absorption of protein in the human body, the sticky protein in egg white, with Soybean Milk in the combination of trypsin, hinder decomposition of protein, thereby reducing the body's absorption of the protein ratio.

Myth four: cook eggs for as long as possible

Egg cooked too long, sulfur ions combine to form ferrous ions and protein in yolk in insoluble ferrous sulfide, it is difficult to be absorbed. Fried eggs are too old, egg white contains high molecular proteins will become low molecular amino acids, this amino acid at high temperatures can often form a chemical adverse to human health. Boiled eggs, preferably cold water under the pan, boil the water, and then cook for 3 minutes. When the egg is soft, the most nutrients help the body absorb. Different boiling time of eggs, the digestion time in the human body is different. "3 minute egg" micro boiled egg, the most easy to digest, takes about 1 hours and 30 minutes; "5 minutes" egg "is a rare egg in the human body, digestion time is about 2 hours long; boiling time of the egg, 3 hours and 15 minutes to digest in the body.

Myth five: raw eggs are more nutritious than cooked eggs

Some people believe that raw eggs have lungs and moisturizing voice effect. In fact, eating raw eggs is not only unsanitary, easily cause bacterial infection, and not more nutritious.

1. egg difficult to digest waste nutrients. Digested egg protein mainly by pepsin and trypsin. The small intestine and have a trypsin resistant material egg in egg white, will hinder the digestion and absorption of protein

2. raw eggs contain avidin, affecting the absorption of biotin in food, it is easy to make the body loss of appetite, weakness of the whole body, muscle pain, inflammation of the skin, eyebrow and other biological deficiency".

3. egg protein structure is dense, and contains trypsin, a large part can not be absorbed by the body, only cooked protein becomes soft, it is more conducive to digestion and absorption of the body.

4. about 10% of the eggs contain pathogenic Salmonella, fungus or parasite eggs. If the egg is not fresh, the infection rate is higher.

5. in addition, raw egg and special flavor, can also cause central nervous system depression, reduced secretion of saliva, gastric juice and intestinal digestion, resulting in loss of appetite and indigestion. Therefore, after the high temperature cooked egg to eat, do not eat unripe egg.
