According to a peer-reviewed pre-publication research article recently published by the journal Environmental Health Perspectives, switching a group of human test subjects from a diet of mostly packaged food to a diet of mostly fresh food led to a rapid and substantial decrease in urinary concentrations of BPA and DEHP metabolites. There is some evidence that BPA and DEHP may be endocrine disruptors and the Canadian government has announced that BPA is banned from baby bottles.

Though the research sample size was quite small the results appear quite definitive. This research is likely to increase pressure on governments to further restrict use of phthalates in food contact applications.
