Eggs contain many different microelements, and therefore they are beneficial for the body.
But some mistakes in preparation can make this product harmful.
Acting Dean of the Faculty of Natural Sciences at the State University of Education Irina Lyalina shared the details, as reported by Doctor Peter .
How to Boil Eggs
The expert drew attention to the fact that eggs from the refrigerator should be placed in cold water and then boiled.
But if they are at room temperature, you can put them in hot water.
It is also important to remember that sudden changes in temperature may cause the shell to crack.
Grey yolk
Sometimes you may notice that the yolk has turned grey after cooking.
But, as the specialist explained, this does not mean that the egg is spoiled.
She noted that this was simply the result of certain chemical reactions.
However, if you cook eggs for too long, they may develop blue-green hues. This may be due to the release of hydrogen sulfide.
Mistakes in cooking
It is also important to take into account that due to some mistakes in cooking, eggs can cause harm instead of benefit.
So, you shouldn't bring them to an active boil. Otherwise, the amount of useful substances in the egg may decrease.
The expert does not recommend boiling eggs for longer than 20 minutes. It is noted that otherwise you can get a dose of hydrogen sulfide.
And this is fraught with the exacerbation of certain diseases or even poisoning.
However, overcooked eggs should not be consumed by children, as well as people suffering from cholecystitis, ulcers or pancreatitis.
Earlier, an expert named the dirtiest item in the kitchen.
