Even if I were to stop putting stuff in the microwave, that won't account for all the other foods I eat outside the home that may have had microwaving as part of their preparation process. I mean, I'll take a frozen package of ribs out of the freezer and microwave it for a minute so the surface softens enough for me to cut the plastic and peel it off before thawing or brining the meat.
No, I think I'll just take my chances and not have yet one more thing to stress out about.
