Microwave radiation from ovens are mild and will just excite water molecules resulting to internal heat generation. I don’t see its sufficient to generate free radicals if the food product being heated or cooked in such radiative environment.

All the vitamins are sensitive by heating in all kind of food.
That is why we need to eat raw vegeteble and fruts.
