“Microwave safe” containers release chemical BPA

I just read this article and thought it was good to share.

This just seemed like a given to me but apparently a lot of people don't know that when a container says "microwave safe" it really has nothing to do with whether or not the plastic will leach BPA, but that the container won't melt in the microwave. BPA is a dangerous chemical that companies in the US are only now starting to warn consumers about despite the fact that plastics that leach BPA are being banned in many countries. You should NEVER microwave plastics that leach BPA, or freeze them either for that matter. Extremes in temperatures cause the plastic to degrade which leachs BPA faster into the food or liquid.

What other options do we have then? Well, there is always glass or ceramic, which may be more expensive, but it will last you longer (pending breakage), heat more evenly and is better for the environment. Another plus that I have found is that with glass, food can be baked, served and then stored, all without changing the container. Less dishes to wash! Yay! One mom suggested looking at thrift stores for old Pyrex which would definitely save a lot.

What plastics should you look out for? You should definitely avoid: #3 PVC, #6 PS, and #7 PC. The "safer" plastics are coded as such: #2HDPE, #4LDPE, #5PP and PLA.

When I first started going to my naturopath, he told me that the plastics also leach estrogen into our food as well. For that reason, I have tried to avoid, (as much as possible) microwaving in plastic containers. Apparently, with the estrogen issue, you can still cover the food with plastic wrap as long as it's not touching it. I have also found that food just tastes better and has a better texture when it's not microwaved. It does take a little more time to heat things on the stove or in our little toaster oven, but it really does allow for better tasting (and safer) food in the end.

I heard they originated in Amish country PA on her show also. I had also seen the marshmallow based cream on recipe searches. You'll have to tell me how they taste! if they are like the old school moon pies or more like cakey oreos.
