New research has linked BPA Free plastic with deformation in fish embryos. BPA (bisphenol A) free plastic is commonly manufactured with BPS (bisephenol S). New research has shown that low levels of either chemical alters the development of fish embryos.
Another study, this time in rats, found BPS caused heart arrhythmia when given in doses equivalent to those humans usually experience. In a press release, study author Hong-Sheng Wang, said, “Our findings call into question the safety of BPA-free products containing BPS.”
Plastic water bottles marketed as being “BPA-free” will likely have levels of BPS.
Food Standards Australia and New Zealand (FSANZ) states on their website that “the overwhelming weight of scientific opinion is that there is no health or safety issue at the levels people are exposed to.”
Despite this, in 2010 the Australian Government announced a voluntary phase-out of BPA used to manufacture baby’s bottles, which are said to be at particular risk of exposure to the chemical.
While the levels of BPS exposure to humans appears minimal, there is no certainty.
An analysis by Choice in 2015 recommended that consumers stick to water bottles made from glass where possible. And besides, glass feels/tastes better than plastic and steel!
