When we fry an egg we add a lot of fats that alter the properties of the egg, unbalancing the fats and natural properties it contains;
the ideal would be to cook it for 10 minutes, then do it hard, so as not to alter any of its properties.
You will have noticed that sometimes some yolks are lighter than others, this is due to the feeding that the hen receives, whether free-range or farmed.

How long can an egg last
Vitamins are also present in the egg white, even if 90% of its weight is made up of water.
The egg can be consumed when you prefer, as long as this does not exceed ten weeks, since after this period of time it is better not to consume this food.
Can eggs be washed?
It is not recommended to wash them, as this practice damages the shell, which works as a barrier against the entry of microorganisms that can damage the product and cause diseases.
If you have to wash them you can do it, but an hour before preparing them, to avoid any alteration.
Can you eat an egg if there are cracks?
It is not recommended, since the cracks allow the passage of microorganisms that can cause diseases.
Sometimes the cracks can be so small that we are not aware of their presence, so we must be very careful when we consume them, in order to avoid damage.
Adding an extra egg to our diet will not cause any negative effects on our body, we just have to be careful about how we prepare it, since that is the only factor that could create alterations.
