So, what’s a BPA?

Labels you might see when purchasing plastic products. (Pro tip: Just avoid plastic all together!)

Labels you might see when purchasing plastic products. (Pro tip: Just avoid plastic all together!)

If you’ve ever paid attention to plastic products for sale, you’re bound to have seen at least a few companies advertising their goods as “BPA-free”. Seeing that on a label leads most consumers to immediately believe that BPAs must be bad for them, but the truth in this situation is a little murky, so here are the facts:

Bisephenol A (or BPA) is an epoxy used to make clear, hard plastics. You see this kind of plastic every single day, whether it be in the grocery store, in vending machines or in the tupperware you use to store your food. It’s often used as coating inside plastic bottles or tin cans. At high-dosage levels, BPAs have hormone like properties. They are endocrine disruptors, and some studies show that they can cause possible negative effects in animals and fetuses, causing birth defects. Some of these effects are stronger when BPA filled plastic is chipped, broken or heated.

In a historic move, Canada has recently declared BPAs toxic. This is upsetting to the American Chemical Council, which says that their product, Bisephenol A, is perfectly safe. One quote from that article said that, “last week, Statistics Canada disclosed that 91 per cent of people tested positive for BPA in their urine, with higher levels for children aged 6 to 11 than for adults over 40. The highest concentrations were in children.”

Most world governments, including the US,  Australia and the EU, have declared that BPAs are mostly safe for human consumption at low levels. However, several countries (even the US) have banned BPA use in products such as baby bottles.

But there are many, many studies supporting both sides of the debate, with the main issue being that studies showing harmful effects of BPAs (even at low does) are hard to reproduce. Scientific American covers the controversy surrounding the issue pretty well.

Wherever you fall on the argument, limiting exposure to possibly toxic chemicals is just another reason to use less plastic. But a life without plastic can be pretty tough. The stuff is ubiquitous! What’s a green-minded consumer to do?

The best way is the simplest, use alternatives.

Whenever possible, refuse plastic, single-use, disposable items. Choose glass, aluminum or paper over plastic whenever you can. Why? Because when items like these are recycled, they can be turned into new and equally useable products. Plastic, not so much. Keeping plastic out of the waste stream is just one more way to make a smaller impact on the Earth, and if it means being a little healthier in the process, even better!

    Alex, that was very informative. I am sure Tupperware appreciates the free advertising…;-)
