Polycarbonate Plastic: It lurks in strange places...

It is very important to know where you might come into contact with polycarbonate, as I discussed in the last post. You will have to start checking your recycle numbers in the same way that you check the ingredients on food labels. Here are some places, though, that you are likely to find polycarbonate plastic:

-Sippy cups.
-Baby bottles.
-Plastic water bottles at the water cooler.
-Nalgene-like bottles that are used for sports.
-Brita Filter - The plastic pitcher that holds the water is made of polycarbonate plastic. The filter is fine, so just get one that attaches directly to the sink, rather than using the pitcher or the large plastic container that has a spigot connected to it (also polycarbonate).
-Inside lining of most cans. Yes, cans. Your soup can, your tuna can, your can used for infant formula. Have you notices that they now contain a plastic liner inside of them? It is good 'ol polycarbonate plastic, unfortunately.
-Baby toys that are made from plastics. You might have to check with a manufacturer to find out what type of plastic is used. However, you MUST do this. I will be discussing the likelihood that our most vulnerable population for all of this plastic exposure are children who have developing reproductive systems. For this group, these exogenous estrogens may cause the most harm.
-Plastic container of the Vitaminx Blender.
-Tooth colored dental fillings as well as dental sealants.

You might be needing to sit down right now and grab a sip of water. Just be sure you are drinking out of a glass. Seriously, we need to demand that these plastic resins are better studied, or studied at all. Many plastics are put into use, with tacit approval from the FDA, which classifies them with a nifty acronym, GRAS. This means it is Generally Regarded as Safe. The chemical companies swear the plastics are not harmful, and there studies appear show that to be true. The studies that were not funded by the industry show that Bisphenol A (BPA) can cause hormonal disruption, pre-dispose a person to reproductive cancers, especially younger people, contribute to insulin resistance as well as Attention Deficit Disorder.

There is actually some good news, though, so stay tuned.

According to Brita, their products contain no polycarbonates whatsoever. See this link (and there are lots of others saying the same thing):
