Doctor Mogerman came in to the small break room one day, watching me heat a cup of tea in a Styrofoam cup (this was over 15 years ago). He casually mentioned how doing so releases numerous toxins not only into the food, but in this case the air. He then went on to say that it is safest not to microwave or cook in any plastic.
Back then, I heeded his counsel. I bought a Pyrex measuring cup for each hospital I worked at as a nurse. Then there were numerous articles on the fact that plastic is safe and there is no evidence of all these bad things. We still limited our use of plastic both at work and home.
Then the first shoe fell, the BPA scare and numerous people chucking their baby bottles.
Then there were all of these urban legends on the dangers of plastic. Some went so overboard as to say avoid all with the #7 on the plastic recycling code. This is unwise. Although the majority should be avoided, some are actually holding promise of being even better than what is currently available.
So, doing some research on evidence based medicine, nursing and other scholarly articles, some surprising results are now available to you.
Rather than going crazy, use a bit of common sense. Avoid the bad where you can. More importantly, use the bodies master detoxifier, Glutathione to get rid of the harmful toxins we ingest in the toxic foods we eat.
Good Health to you.
