Many people think microwave ovens may be dangerous. While the experts keep assuring us there is nothing to worry about, one can't help but remember the doctors and other experts not too long ago telling us that cigarettes are safe.
Safety fears are numerous. Some people worry about leaking radiation. Others are more concerned about the damage the microwave does to the nutrients in food. Many studies have shown a significant reduction in vitamins and antioxidants when food is microwaved.
Another concern involves the leaching of chemicals from "microwave safe" cookware. Many different dangerous compounds are used in common materials. When you heat food in items made from these materials, you increase the likelihood of extracting those dangerous chemicals. And where do they go? Right into your food.
So why do the experts consider this to be safe? Well, the amounts leached are considered to be below levels that cause concern. But how do they keep track of when those levels are exceeded in an individual? How do they know how many times in a day you are exposed to BPA or other dangerous chemicals?
All in all, I personally am not convinced that microwaves are safe or unsafe. There are just too many unknowns for me to make an intelligent decision in the matter. So I mostly use my toaster oven.
