I'll be a bit of a contrarian here. I've posted on BisA in the past and my thinking has evolved some since then. I haven't worried about soy-based compounds, so I'll limit my remarks to Bisphenol-A, but the truth is that we really don't know if BisA does cause the changes that scientists see in animals. There are actually quite a lot of animal studies of very low concentrations that show the possibility of harmful changes for people. But, without the proper human studies, we really can't say one way or the other. The EPA says it is safe, but that is based on very limited data so far.


Hey Arney,

I know we have discussed this issue here on the forums in relationship to some of the questions raised with BisA release from polycarbonate waters bottles and I think for the most part we have presented some fairly strong arguments against it being a health issue.

I just want to make sure that others do not interpret your statement above as a reversal of that position. If I am interpreting your statement above correctly, you are referring to actual studies with BisA and not the “reported” release and subsequent effects from animal water bottles made from polycarbonate. As I have stated before, if this were an actual and valid observation, the effects should have be seen (and it has not) on huge number of rodent studies (including control animal), since the use of polycarbonate water bottles and cages in animal facilities have been used for at least two decades.
