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.
I may not be but, in combination with other common chemicals might be harmful.
There's something that's making us, as a nation, generally obese/ill and no one has been able to pinpoint exact causes.
(please don't site a longer life span as a rebuttal. We again, as a nation, are basically dependent on the pharmaceutical industry and healthier lifestyle choices for that stat)
