When you shop at places like Whole Foods, you often assume what's "green" is also "healthy." That's not the case. I've been railing against Nalgene and Sigg bottles forever, and everyone thinks I'm crazy--what could be wrong with thise cute, reusable bottles? Well, they contain BPAs, which are ENDOCRINE disruptors.
Studies conducted at the University of Cincinnati several years ago found some rather disturbing results in regards to the low-level impacts of BPA. In fact, Dr. Belcher said, while high doses cause little effect, analysis of cellular and molecular markers of estrogen signaling revealed that near-maximal effects of BPA on rat brain neurons not only occurred "at surprisingly low" doses of 0.23 parts per trillion, they also happened in a matter of minutes.
"From other studies it's clear that these low concentrations are in line with human fetal exposures, and at levels one might even see in the water supply," said Dr. Belcher.
From our friends at Science Daily:
(June 12, 2009) — Exposure during pregnancy to the chemical bisphenol A, or BPA, found in many common plastic household items, is known to cause a fertility defect in the mother's offspring in animal studies, and now researchers have found how the defect occurs. The results of the new study will be presented June 13 at The Endocrine Society's 91st Annual Meeting in Washington, D.C.
Sigg is backpedaling on their insistence that Sigg bottles are "safe" but admitted they are NOT BPA free and you can exchange them for some other bottle with a new, green "Eco liner." Here's a letter from SIGG's CEO to consumer:
I have learned much over the past 2 weeks. I learned that many of you purchased SIGG bottles - not just because they were free from leaching and safe - but because you believed that SIGGs contained no BPA. I learned that, although SIGG never marketed the former liner as “BPA Free” we should have done a better job of both clearly communicating about our liner as well as policing others who may have misunderstood the SIGG message.What is in this new "eco liner" is anyone's guess. The FertilityBitch's advice to keep your waterbottle BPA free? Just like that old adage, the only way to make sure you don't get pregnant is to not have sex, well, if you don't want BPAs, use an old glass bottle, or go stainless. I like New Wave Enviro stainless steel bottle.
For over 100 years, SIGG has earned a reputation for quality products and service – and we do not take that for granted. From the day we made our announcement last month, we made a commitment consistent with SIGG values that we would offer anyone who is concerned about BPA an opportunity to swap their old SIGGs for new SIGGs with the new EcoCare liner. Today, I am announcing that this voluntary Exchange Program will be in place until October 31, 2009 to ensure that our customers have ample time to send their former liner bottles back to us should they choose to do so.
Simple and clean, and you can even get a stainless cap to go with it and really eliminate all the plastics from your life! Plus, these bottles don't dent as easily as the SIGG's (made of--ugh--aluminum).
