You can decide for yourself after reading this article (follow the link below).  I’ll give you a hint though, NO!  Not even to heat up water.  Get rid of it, or at least move it out of the kitchen so you aren’t tempted to use it.  you can easily cook and reheat everything you eat on your stovetop or in a regular oven.  For reheating food like rice dishes or pasta, place a tablespoon of water in the bottom of your pan (preferably not aluminum or scratched up teflon) and then place the food you wish to reheat in the pan.  Cover with a lid and heat over medium heat for a few minutes.  The water prevents the food from sticking to the bottom of the pan.  Other items like lasagna or burritos (made with whole grains of course) can be reheated in the oven.  Wrap them in unbleached parchment paper to keep them from drying out.  ok, go!
