More problems with bisphenol A, maybe

A new study links bisphenol A, the chemical that leaches from #7 plastic bottles, with heart disease and diabetes.  People with higher levels of bisphenol A in their urine had a greater chance of having heart disease and diabetes.  Does this mean bisphenol A causes these conditions?  It could, but it also could mean that some other factor is responsible for both or this is just a coincidence.  While waiting for the inevitable further research, it seems reasonable to use something other than #7 plastic bottles (unless you know that the ones in the #7 category do not contain bisphenol A). The study is published in the Journal of the American Medical Association along with a cautionary editorial.
