The debate over bisphenol A, or BPA, resurfaced this week after British researchers revealed a study on the potential effects of the chemical on 1,455 U.S. adults.
The study found that people with the highest concentrations of the chemical (used in baby bottles and beverage can linings) in their urine suffered a higher rate of heart disease, diabetes and liver-enzyme abnormalities, Reuters reported.
In April, Canada banned the substance from use in baby bottles. The U.S. Food and Drug Administration issued a draft conclusion in August that current exposure to the chemical fell within safe levels. The administration said this week that they would review the new study, but still believed exposure levels to be safe.
