Bisphenol-A (BPA) is a chemical used primarily to make polycarbonate plastics (e.g. bottles, food containers, processing equipment) and epoxy resins (e.g. protective linings in cans and bottles). Worries about this product started back in 2008, due to BPA’s “hormone-like” properties. It was declared a toxic substance in Canada in 2010.
BPA is thought to contribute to many health conditions (eg. obesity, cancers, thyroid dysfunction). One of the scariest effects, however, is on reproductive function and outcomes. Any BPA a woman is exposed to during pregnancy may also effect her baby. Similarly, exposure as an infant may be unsafe. One of the most concerning sources of BPA in babies are bottles. Fortunately, BPA has been banned from baby bottles sold in Canada. BPA's effects seem to primarily affect girls, including behavioral changes (e.g. aggression and hyperactivity noted as early as age 3).
How to avoid BPA
Plastic bottles
If your plastic is marked (usually on the bottom of the container) with recycle codes 1, 2, 4, 5 or 6, it is unlikely to contain BPA. Avoid recycle codes 3 or 7 as they may contain BPA.
Canned foods
Many canned foods contain BPA. If possible, try to buy food in glass bottles/jars or cartons. Here is a link to a Health Canada website that details some food brands and their BPA contents:
Cash register receipts
Some cash register receipts also contain BPA. Either ask for no receipt, or have it placed directly in your bag (not touching food). Always wash your hands after handling it.
Following these simple steps can help reduce your exposure to BPA and in turn minimize the risk to your family.
