Microwaves disrupt the body's Bio-electric Field

     As you practice and learn more, you will understand that everything i in effect energy.  Even mass is energy, as Einstein postulated in E=MC^2.  This is also important to know.  In essence, it means to that Energy can be converted to mass and vice versa.  This also means that any outside electromagnetic interference or other wave forms can effect the mass of biological organisms.  Further studies indicate that waveforms such as microwaves can change the molecular structure and shapes of molecules.  For instance when you microwave   food  or water, the microwaves, changes the angles of the molecules so fast that it creates molecular frictional heat, thus the food is heated.  However, the side effect is that many of the molecules have a shape change.  This means that vitamins and minerals, although still present, is no longer in a recognizable form by the body. Basic tests of quantity of these molecules will conclude they are still there.  An analogy is this.  You look at 2 lots of cars.  They both contain 100 cars.  However one is a junkyard, in which the cars re not working.  The other is a lot o new cars that can help you travel to places that the broken down cars cannot.
     Getting back to the shape of molecules and biological effects.  If you know that the molecules are now unrecognizable, the biological effects are amplified in terms of negative effects on the body.  Since the body does not recognize the food as normal, the immune response kicks in.  We now have white blood cells entering the Large Intestines through the capillaries in the micro-villi.  They attack the deformed proteins and molecules and treat them as foreign to the body and as toxins.  The molecules that are absorbed into the gut now increase the risk of gasto-intestinal cancer.  The molecules that make it into the blood stream goes to the liver for processing.  Now the Liver is overwhelmed, and also has an increased risk of developing cancer.  This of course is very bad for the human body.
     On top of the problems with nutrients becoming toxins, we have water molecules.  Normally, water molecules have the oxygen and 2 hydrogen molecules at an angel of 104degree30.  In a microwave this angle is changed drastically to between less then 80 degrees to more then 120 degrees.  Now the water molecule is considered abnormal to the human body.  It is now also a toxin that causes the body upon consumption to leech out healthy water to dilute the unhealthy water molecules, causing cellular dehydration. Cellular dehydration causes the cells to function improperly and can lead to biological problems that we today cause disease.  Of course this is just a rough breakdown of what happens inside the body that causes the bio-electric field to to longer be in balance.  I will give some info to sources and links to these links in a few days.

Alternatives to using microwave ovens can be to use a conventional oven or a infrared oven.  I personally use a NuWave oven and love it.  The food actually taste pretty good.  The other alternative is Black & Decker.
