It has been known for some years that the problem with microwaved anything is not the radiation people used to worry about, it's how it corrupts the DNA in the food so the body can not recognize it.
Microwaves don't work different ways on different substances. Whatever you put into the microwave suffers the same destructive process. Microwaves agitate the molecules to move faster and faster. This movement causes friction which denatures the original make-up of the substance. It results in destroyed vitamins, minerals, proteins and generates the new stuff called radiolytic compounds, things that are not found in nature.
So the body wraps it in fat cells to protect itself from the dead food or it eliminates it fast. Think of all the Mothers heating up milk in these 'Safe' appliances. What about the nurse in Canada that warmed up blood for a transfusion patient and accidentally killed him when the blood went in dead. But the makers say it's safe. But proof is in the pictures of living plants dying!!!
