i am sure that it destroys some of the nutrients in the egg...but so does cooking them in a pan, and so does breaking the yolk... the amount of fat/protein/cholestrol/arachidonic acid/overall calories in the egg is probably going to be completely untouched no matter how you eat it though. ....i have been microwaving eggs since before i even started lifting weights. the best way is to beat the eggswith soem cayenne pepper, chili powder, salt, and granulated garlic and then pour the mixture onto a paper plate in the microwave....microwave untill the whole thing is almost cooked, the pour on some hot sauce(preferably tapatio saucce) and stir it up, then nuke it for the rest of the time.....very good taste
