65% of women admit to heating their baby's bottle in the microwave, despite all the warnings against doing so. Standard advice for heating a bottle is to let it sit in a pan of warm water in the sink for a few minutes until it reaches room temperature.
But, most time-pressed moms are skipping it anyways. Testing done a while back by the Milwaukee Journal Sentinel with the help of Dr. Frederic vom Saal, a leading BPA expert, concluded the following:
“There is no such thing as safe microwaveable plastic. As you heat it, you degrade the chemical bond. You can’t see this happening. You can’t taste it, you can’t smell it, but you are getting dosed at a higher amount.”
Even microwave safe bottles or plastic that have been designed for use in microwaves undergo testing by the Food and Drug Administration (FDA) to ensure that the plastic will retain its shape under high temperatures and have the “least amount of leaching possible.” Leaching is considered to be safe provided that the amount of leaching is within “certain parameters” for the type of plastic used. Well that’s not very comforting!
