A few days ago a friend of mine asked me why I always drink from my specific water bottle. She had no idea what I was on about when I answered “because it’s BPA free” which then brought to my attention that perhaps a lot of people are unaware of what BPA is and how it can effect our body which lead me to write this.
BPA - Bisphenol A - is a compound used to make plastic. It was known to be estrogenic in the 1930’s and was covered by the news media regularly in 2008 after several governments questioned its safety and therefore prompted retailers to remove products containing it from their shelves. In 2010 the FDA - Food and Drug Administration - raised further concerns with exposure to infants and children. Shortly after, Canada became the first to declare BPA as a toxic substance and as well as the European Union, have banned its use in baby bottles.
So what exactly can we find BPA in? As it is a compound used for making plastic it is abundant in many everyday products such as; baby bottles, water bottles, sports equipment, medical and dental devices, dental fillings and sealants, eyeglass lenses, CDs, DVDs, and household electronics. BPA is also found in Epoxy resin used for coating almost all food and beverage cans.
What effect can it have on our body? BPA is an endocrine disruptor meaning it disrupts our hormone system. Our endocrine system is in charge of a lot in our bodies than you might know and if disrupted it can be a major threat to your health. Government-funded BPA studies reported a variety of effects such as: abnormal weight gain, insulin resistance, prostate cancer, and excessive mammary gland development, erectile dysfunction, breast cancer, neurological issues, heart disease, polycystic ovaries and thyroid dysfunction.
Luckily there is a way to identify plastics that are marked with recycle codes. Codes 1,2,4,5,6 are very unlikely to contain BPA and most plastics marked with codes 3 and 7 are most likely to contain BPA.
You can find recycling codes on the bottom of your water bottles, they look like this: http://english.arhdev.net/?p=59
