BPA Replacement Hinders Heart Function, U of G Study Finds

Person opening a can of food (Istock credit: Mario)BPA’s counterpart replacement BPS can hinder heart function within minutes of a single exposure, a new University of Guelph study has found.

The study is the first to show the instant effects bisphenol S (BPS) can have on the heart.

“We expected to find similar effects from BPS as we have with BPA, but not at the speed that it worked,” said Glen Pyle, a biomedical sciences professor at the University of Guelph’s Ontario Veterinary College, who conducted the study with former master’s student Melissa Ferguson. 

Bisphenol A (BPA), a chemical used in plastic products, was banned from baby bottles in Canada in 2010 over concerns that it may leach into foods and cause hormone-related side effects. More manufacturers are now using BPS as a replacement in their products and labelling them as BPA-free.

During the study, when mice were given bisphenol BPA or BPS in amounts that mimicked typical human levels, their heart function worsened, especially in females, within minutes of exposure.
