This is a subject that I came across a while back and have spent some time exploring, but this week Beth Terry of myplasticfreelife put up a post that covered the topic perfectly. I highly recommend reading her post about the other estrogenic chemicals that can leach out of plastic and into your food and water. You should also follow her on twitter @plasticfreebeth
The whole post is a great read (so check it out!), but here are a few crucial facts about why we need to move away from disposable plastics and find a more sustainable solution. This is what Beth has been doing since 2007 and her blog is full of advice and information on how to reduce your plastic footprint.
Many brands are now advertising that their products are BPA-free. From baby products to bottled water, companies have been quick to jump on the bandwagon and now advertise that they are BPA-free. As Beth points out "entire shelves of baby products are labelled BPA-free. Are they safe?" Companies want us to believe that BPA-free means that the chemicals used in their plastics are safe, but just because a product is not made with Bisphenol-A does not mean it is safe.
Beth took a 33 page study from the University of Texas and presented it on her blog in a way that is very easy to understand. A big thanks to her for the great work she put in. The UT study "confirms that hormone-disrupting chemicals leach from almost all plastics, even BPA-free plastics." What does that mean? All those baby products and water bottles can still leach chemicals with Estrogen Activity into beverages and foods that are stored in them. This is bad because chemicals with Estrogen Activity "mimics the hormone estrogen in the body" and can cause a variety of health problems.
Have you ever left a bottled water in your car while you went to shop or see a movie? When you came back did the water taste different? If it was a sunny day the odds are that are that some chemicals leached from the plastic PET bottle into your water. Why is that? In the UT study researchers also tested plastics under duress and found that "plastics are more likely to leach chemicals when exposed to various stressors like heat or light, the researchers also tested the products after subjecting them to UV radiation (mimicking the effect of sunlight)". So let's review. Disposable plastics are destroying the environment, cost more money, and also leach chemicals into food and water that disrupt hormone levels, check. Sounds like a great product line.
As I have written about recently, some companies are now touting a new bio-based plant plastic that is not made with petroleum. These new plastics are still not biodegradable and further "71% of all the PLA samples tested were found to leach EA chemicals as well". Do not buy the hype about plant based plastic, it may be better than petroleum based plastic, but it is not safer for you as the consumer.
Make the decision to use less plastic every day. Why buy plastic water bottles when the water in your home is cheap and also most likely safer to drink? An obvious first step to reduce how much plastic you buy is to put down the bottle and take control of your water.
