There have been claims of serious biochemical changes to the structure of proteins and amino acids in microwaved food and I believe that, for safety’s sake, it is important to avoid meals cooked in this way if possible.

What you can do:
Increasingly, there are allegations that the packaging of microwave-ready foods may release harmful toxins, so if a microwave must be used, put the food onto a plate before cooking it.
Be aware that radiation leaks from the seal of the microwave oven door, so children should not be allowed to stand nearby when it is on.
