Nutritional value of the product
Raw eggs
Some people probably do not know that raw eggs can not be eaten in large quantities , since the substance that is part of the chicken egg (trypsin inhibitor) greatly slows the digestion process. But in the boiled it is no longer, because at 70 degrees it is completely destroyed. Therefore, heat- treated eggs can be eaten without fear.
So, as we have seen, the composition of the egg is very complex and diverse. Its components are essential elements for a balanced diet. Refuse to take this valuable food will have only those people who have an allergy to it.
