BPA – bisphenol A – Should you care?

There has been an amazing amount of articles, studies, news, journal articles and a great deal of controversy around BPA.  Many companies, and groups are cautioning everyone to avoid products that could expose you to BPA.  With all the controversy and articles that state the dangers and many that with just the opposite opinion, what should you do?

My though process is simple.  If it is a non-natural chemical, and it has this much controversy . . . then I would recommend that it simply be avoided. 

Based on the Wikipedia BPA entry, it seems that it should be avoided, and you should care as the effects although not outwardly apparent in the short term would at most exposure levels have an effect on your health or the health of your family. 

For a great insight into this subject I recommend picking-up and reading the February 2009 issue of Fast Company magazine .  The article titled, “The Truth about BPA” raises very interesting questions about the chemicals we expose ourselves to everyday and the process or lack there of in determining the toxicity, safety and overall impact on ourselves and our environment.  Once the article is available online this article will be updated with a direct link.   (now available) 

Given the great controversy we at Green Benefits have chosen to offer a wide selection of steel, aluminum and plastic, ‘BPA free’ water bottles and drink wear.
