Lead researcher Professor Richard Sharpe said that while there have been a number of studies linking BPA with a number of health risks, including diabetes and infertility, it does not mean that the chemical itself is causing the illnesses.
Instead Professor Sharpe said that people who are obese or eat modern western diet have higher levels of BPA in their bodies.
"None of these studies actually shows that bisphenol A exposures causes the disorders, the exposure is simply associated with occurrence of the disorders. If this association was due to cause and effect, it would mean that bisphenol A was incredibly potent and toxic, and this does not agree with published studies. This possibility therefore seems illogical", Professor Starke said.
