This is another one of those myths. Friends are well meaning and repeat what they've heard or read online. I don't reheat food in a plastic container, mostly because the container might warp and a good one is expensive to replace. I have some Anchor glass containers that stand up well to reheating, and then I never worry about exposure to plastic.

There is even a "cancer clinic" down in Tijuana, MX that cautions their patients not to heat up their coffee in the microwave. That's such a horrible guilt trip to put on people with cancer.

1. Microwaves can leak. That, in itself, is a danger.

2. Microwaves change food properties. No one actually yet knows, specifically, what that does to a body.

3. Microwave heated food, including water, can actually explode once the surface tension is actually interrupted.

4. Despite instruction to the contrary, it is best to heat microwave food in glass containers.

5. To each his or her own.

I don't believe the myths, but I also have never been a fan of how a lot of foods taste that are cooked in the microwave. Thanks for posting because all too many people do believe the myths.

Another example of how something, anything, or everything is supposed to kill us in some way or another. I use a microwave every day since they first were getting popular. I haven't grown a third eyeball yet, and don't expect to. Take anything that exists and someone, somewhere is going to say that it's bad for us and will surely kill us.

I'll take my chances, now.....my coffee is cold.

I like the taste of vegetables that are cooked in the microwave better than vegetables cooked conventionally. I also think microwaving vegetables is better for me as I tend to boil, steam, and roast vegetables much longer than necessary.
I do keep my microwave covered so the Space Aliens can't spy on me :)

I use my microwave for veggies and for heating non-meat dishes. And heating water for tea. It's so strange how these myths keep circulating. I will keep using mine as long as I'm on this planet. Makes life easier.

"The truth", said Voltaire, "is the lie commonly agreed upon."

It's not those who spout such "facts", it's those who believe them!

I have been on the side that it is a myth and part of all of the other "alternative" movement's talking points. I have always done what I thought was best for me regardless of what things like this myth says. Sometimes you have to follow what you think is correct. There are so many of these silly myths and ideas about how to cure cancer sometimes I just ignore all of them.

I don't use one to cook, only to reheat leftovers. I also use only microwave safe glass and/or plastic. I don't find it changes my food in any way, since I only reheat.

Just to be safe I wouldn't use a Microwave but if you have to stay ten feet away.

I use ours to reheat a few things. Not much really, but I have no fears whatsoever about it being a cancer-causing machine. If you look hard enough you can find an article or a study that says that anything causes cancer. Sometimes you need to look at who paid for the study and take that into consideration before you start throwing away whatever it is that was supposed to be causing cancer.
