Do you own a microwave? Most of us do these days – and that is a good thing.
There are so many myths associated with them. Heating from the inside out for example. Not true.
A source of radioactivity? There is NONE. Your body is more radioactive than the microwave. What? Well, it depends what we mean by radioactive. Microwave Radiation is not the the same as radioactive radiation.
Are they dangerous?
Some say yes: http://www.relfe.com/microwave.html
Most say no: http://elgringosalsero.hubpages.com/hub/The-Myths-About-The-Dangers-Of-Microwave-Ovens
I think the case for danger is extremely weak. Of course, it’s your choice.
Microwaves are 70% more efficient than an oven. True.
So my tip here is to remember to use the microwave.
Rather than immediately – and unthinkingly – using the gas or electric range and oven in your kitchen, give your microwave more work to do.
