Why is BPA used at all when there is such a controversy about its safety?
In short, Bisphenol A or BPA is needed to harden plastic.
In coffee makers, the inner parts like the water tank or the coffee filter basket are made of plastic. These parts are in direct contact with the end product: the coffee you drink.
A couple years ago the FDA announced some potential concerns about the health effects of Bisphenol A:
There is “some concern” about developmental and reproductive problems in infants and children exposed to BPA.
You see they specifically referred to infants and children which is worrying enough for all the Moms and Dads.
In the last years, there have been a lot of controversial discussions among the experts whether BPA is also dangerous for adults or not. The FDA has not, in any event, found any convincing evidence for Bisphenol A to be harmful to adults.
Still, many coffee manufacturers have started to produce BPA free coffee makers.
In my opinion, even when the FDA assures that BPA is not harmful I think it is better to be safe than sorry!
And there are still not so eco-friendly coffee makers out there so your decision to search for a BPA free coffee maker is a very smart move!
