You can't "harm" the protein or nutrients in an egg. Cooking the egg enough so that the egg white turns white causes the albumin protein to denature, or rearrange, because of the heat. The nutritional properties are not affected. You should be more concerned that your egg is cooked thoroughly enough to kill any food borne pathogens such as Salmonella and E. Coli.
yes, because many of the nutrients in boiled foods are lost, they breakdown.
There would be about 18.87 grams of protein in 3 boiled eggs of average size.
One boiled egg contains approximately 6 grams of protein and 80 calories.
Vegitables do lose some nutrients when cooked, but are still healthy.

The proteins and nutrients in an egg cannot be "harmed". Cooking an egg so that the albumin (the egg white) turns white is caused by the proteins denaturing and changing shape due to the heat. There's absolutely no evidence that this denatured protein has any different effect on the human body than the raw egg white. Boiling an egg will not appreciably affect its nutritional content. More of concern should be that the egg is cooked thoroughly to destroy foodborne pathogens such as E. Coli and Salmonella. Contracting food poisoning from uncooked foods is a far greater danger than any postulated "loss of nutrients" from boiling an egg too long!

Boiled eggs to give her protein>
Yes they can be. protein shakes have chemicals in them, not just protein eggs are ALL NATURAL protein especially hard boiled eggs.
There are approximately 6 grams of protein in one large boiled egg (or unboiled).
The blackening seen on a hard boiled egg, left open to the air is a result of oxidation of the protein component. Atmospheric oxygen reacts with parts of the protein molecules causing discolouration.
A 4 oz chicken breast has about 20g of protein. One large hard-boiled egg has 6g of protein. So you'd have to eat 3 hard-boiled eggs to get roughly the same amount of protein.
