All plastic is chemical. This includes Tupperware. Which chemical is good and which is bad are very difficult questions to answer even for experts. Most 'experts' have commercial interests.
Tupperware is among the best tested (and marketed) food quality plastics 'today'. No one knows what lab tests and 'real tests on consumers' might reveal in a few decades. The intent of this blog post is to "prove all plastic is bad for use with food". Tupperware is discussed here because it is popularly thought as the 'safest'. I do not have anything against the company and appreciate the openness in the FAQs in Tupperware website, which acknowledges the use of "bisphenol A" in their products.
Thanks to Tupperware for this statement:
"As we have the highest regard and concern for the safety of our consumers, however, we will continue to closely monitor this scientific debate and conduct our own research into the best materials for use in Tupperware products."
This means we are guinea pigs. We are living in the cool lab of consumerism. All this is shocking to me is because, I went purely by the hype around Tupperware. I thought since it is expensive, it must be safe. How foolish I have been.
"bisphenol A" is a chemical in most plastics including some Tupperware as acknowledged by them in their website .Wikipedia says this chemical is an endocrine disruptor and can play with your hormones.
'Safety standards' are only 'evolving' guidelines and most probably have commercial bias. The 'safest plastic' may be proved to be hazardous after 10 years from now. That might be too late for you. The point I am trying to make is not just about bisphenol A in Tupperware, but about the whole idea of using chemicals with food.
Special thanks to Vignesh for asking that question in the comment in my earlier post, which urged me to find these facts out. btw, does anybody know the chemical effects of my hot Sambar's tartaric acid on bisphenol A ?
