I would be concerned about the build up over time and if this toxin stays in your body. Think of all the plastic on a daily basis. Is it also in plastic water bottles, pop bottles?
May make sense to try and reduce exposure.
As far as I know there is no conclusive evidence that BpA is harmful. Second, if it were conclusive it would be banned outright not subject to control. Third, I have yet to see where the body cannot eliminate this substance.
I admit to not spending a lot of time researching this but in the articles I have read it seems, once again, we have consensus but actual hard data approaching proof.
That would be my thinking on this.
