Microwave ovens really are bad for your health. I know from personal experience that after eating microwaved foods, or standing close to a microwave I feel less alert, and sometimes actually ill. Microwaves also change food - changes in the way it looks, the texture, the smell, the taste. I, for one, can tell the difference between food that's been microwaved and food that's been heated in an oven. Oh, I know that everyone is bombarded by radio waves of all sorts all the time, but microwaves are a particularly concentrated source. Check this out and see the evidence for yourself. As for me, I avoid eating microwaved food and being in the vicinity of a microwave. It may be overly cautious, but I'd rather avoid them than learn later, the hard way, that microwaves do actually cause harm.
