Hi, Was reading the news this morn and tripped across a brief article about BPA in plastic. I know it's not a good ingredient so I always look for 'BPA-free' products when I buy anything plastic.I don't buy disposable plastic water bottles ( for me and the environ) but I do have reusable ones I drink out of everyday. Turns out there's more to the story.( BPA- free plastic can still release a toxic substance called BPS into your food or liquid. BPS stands for bisphenol S) Also found in receipts, lining of tin cans et.al. The article said (I'm paraphrasing) "ingesting even small amounts can mimic estrogen and change the way our endocrine system functions; these changes can be linked to chronic diseases like diabetes, asthma, and others." They didn't mention rls but the article did mention that studies with unborn animals' exposure can lead to impaired brain development and immune system" In my mind, this is messing with the nervous system, so perhaps rls isssues could be involved (my thought). The article did say to stick with glass or stainless steel containers (WITHOUT an epoxy lining.) Didn't know there was such a thing. Sometimes I feel that for every bad ingredient removed from food it is replaced by another one that may be worse. I've been buying BPA plastic for awhile. Time to change.. Just wanted to share this info. I try to keep up but this was news to me. Hope this helps someone. BTW- I know I've benefitted medically from animal research but it makes me sad that it goes on and no one has discovered a way to leave the animals in peace. Just my opinion. Thanks for listening.
