What About Microwaving Plastic Containers?

The recent news about the possible health risks of using polycarbonate bottles (like ones made by Nalgene) has made me a little uneasy. Now I'm wondering about about the relationship between microwaves and plastic, like the reusable food containers I heat up almost daily.

Are the high temperatures leaching chemicals into my food? Should I use ceramic or glass containers instead? To find out


According to the FDA, microwaving plastic food containers is safe, and although small amounts of chemicals from these containers may leach into your food, the amounts are small enough that they can't harm you. This statement is not exactly the reassurance I was looking for.

Fit's Tips: It's recommended to use containers that are specifically marked "microwave safe." Margarine tubs and yogurt or carryout containers from restaurants should not be reheated in the microwave. If you're unsure about the container, reheat your food into a regular plate or bowl instead. Or if you don't want to deal with plastic containers at all, you may want to pick up some glass containers with lids.

All I know is that when I used to work at a research lab full of scientists working on all sorts of environmental and health research, NONE of those scientists would ever microwave anything in plastic. So....

I'm with Wackadoodle. LIVE YOUR LIFE! We live longer in developed countries for a reason. Thanks to chemicals our food and water is safer. I think people are getting very carried away with the plastic phobia. There are real dangers out there--war and famine just to name a few. Let's worry about the important stuff.

I do not own a microwave anyway, and don't plan to own one.

It's all good, because I'll use my Kinoki foot pads to remove the microwave-induced toxins from my body....

Canada has banned those types of chemicals/bottles all together and Nalgene is reformulating their bottles not because of the harm (no one is supposed to heat a Nalgene anyway) but because of consumer demand. Microwaves not only release chemicals but also dont' necessarily draw out the nutrients in foods like simply heating on the stove or in the oven would do. If microwaves only heat the food which in turn heats the plastic, why is the plastic always hotter than the food? Regardless of what we have been told or raised to believe, just because something makes life easier, doesn't make it 100% healthy. I don't think microwaves are evil and if i reheat my spaghetti in plastic every once in a while, I won't die. But, I plan on phasing out my microwave more and more and my plastic...just because there are things that make sense to me and that's what I choose to do. I take very little value to what the FDA has to say, after all, they allow high fructose corn syrup to be in everything under the sun...

Look I am at the verge of just ingesting everything plastic and chemical laden just to spite all of these stupid overzealous warnings that come out every other day. For cripessake! I'm not nuking something for an half and hour. It's 30 seconds and the plastic never gets hot. Apparently people don't understand that microwaves heat water molecules in FOODS and then the food through radiate heat will eventually heat the dish. Geez wiz this is like going backward and trying to convince my grandma that the microwave isn't freakin' Satan in a box! She honestly believed that microwaves were evil and were sent to man by Satan itself to bombard us with radioactivity. I had to tell my grandma that we get more radioactive exposure from the Sun and from our TVs than we do from microwaves. The woman flat out refused to eat or drink anything that came from the Devil's hotbox. She refused to allow one in her house or garage too. CRAZY!

I only microwave things in glass containers because I HATE how plastic gets stained when you heat stuff up in it. I figure, if the food is getting into the plastic, the plastic must somehow be getting into the food. When I DO use plastic, I check to make sure it's microwave-safe.

my boyfriend was trying to convince his friend that microwaving in a plastic container is safe. he said, if it's safe, it would say on the container. I showed him the container and said, um, it does. i swear people just repeat stuff they hear without thinking bothering to think about it or research it themselves
