Are BPAs dangerous?
I have always been very sceptical about the reported dangers of BPA (Bisphenol A) – I never really read anything that was conclusive – but then again I always seemed to buy BPA free drinking bottles for my kids (just in case!). I guess I was not really convinced about how much of BPA could actully leech into my drinking water or food while cooking. So I was alarmed and interested by the news headings recently “BPA, phthalate exposure may cause fertility problems” – CNN.com and “Is BPA Harmful for Pregnant Women?” – weather.com. Reading through these articles I realise that although there is a lot of emphasise on the “may” and that nothing is conclusive, there does seems to be evidence that it BPAs can affect male fertility and “may” increase the risk of miscarriage.
This also made me think about the affects BPAs might be having on my young kids. I also came across an article linking BPA with childhood obesity (Chemical BPA linked to children’s obesity) – BPA is known to disrupt your body’s metabolic mechanisms, according to the study authors, which could affect your body’s ability to control its weight. The article also suggest that the affects of BPAs will be greater on children below the age of 6. Once I started reading I kept coming accross mroe and more alarming articles: BPA increases breast cancer risk; prenatal BPAs link to depression; BPAs link to Asthma and many more!
So what is BPA?
“It is a colorless solid that is soluble in organic solvents, but poorly soluble in water. BPA exhibits hormone-like properties at high dosage levels that raise concern about its suitability in consumer products and food containers where exposure is orders of magnitude lower.”
The Food Standards Code Australia says:
“Bisphenol A (BPA) is a chemical used in the lining of some food and beverage packaging to protect food from contamination and extend shelf life. It’s also used in non-food related products. People are exposed to BPA because small amounts can migrate into food and beverages from containers. Reports from some animal studies have raised potential concerns that BPA exposure may cause multiple health problems. However the overwhelming weight of scientific opinion is that there is no health or safety issue at the levels people are exposed to.”
It seems that no one can definitely say whether BPAs are dangerous – but I think I will err on the side of caution and try and avoid BPAs as much as I can.
Ways to Avoid BPAs
