I was on MC yesterday, so I had the opportunity to watch a documentary on RTM1... which was about plastic. Just thought of sharing this info, so that we can start looking for a safer option.
One of plastic compound, Bisphenol A (BPA in short) is actually capable of altering body hormones. Since BPA is used in plastics... therefore you can find it in the most common thing that we used everyday... such as water bottles & baby bottles...
FYI, BPA is released even though the bottle is only filled up with cold water and in room temperature... if heat was added to it, more BPA will be released.
A little extract from wikipedia on BPA effect on our health:
Bisphenol A has low acute toxicity, with an oral LD50 of 3250 mg/kg in rats, but it is an endocrine disruptor. Low doses of bisphenol A can mimic the body's own hormones, possibly causing negative health effects. There is thus concern that long term low dose exposure to bisphenol A may induce chronic toxicity in humans.
