Definitely. I call them "food poisoners". You put protein in the food poisoner, and the radio waves scramble the amino acids. The molecules are also messed up so they create compounds that didn't exist--more so than just heating the food would. Infra-red does not do this (that is common heat).
However, even worse is what goes into the food poisoners. If you have a TV dinner, take a look at the ingredients. Chances are good that you are going to find items like hydrolyzed vegetable protein (), autolyzed yeast, textured soy protein, soy protein isolate (as often as not, contaminated with hexane), and even good old fashioned monosodium glutamate. This stuff will ruin your brain, whether heated with a microwave or IR. Virtually everything that goes into the food poisoner has some form of hidden monosodium glutamate, high fructose corn syrup, or aspartame. Not to mention that it is loaded with bad fats (that become worse with the microwave radiation) and excess sodium. They are also deficient in vitamins (nuking them destroys what little vitamins they had) and minerals like magnesium.
