I try to be a reasonable fellow and not get too caught up in sensationalism or fear. It’s sometimes more of a challenge today with the media, special interest groups and of course the Internet (more a venue for the first two but I digress).
Of particular interest to myself is the recent debate over BPA and polycarbonate plastics used in storage. While using them for non-food related storage is no problem there have been studies showing that BPA (a chemical used in the production of polycarbonate plastic) leaches into the food or liquid contained within. Both the chemical companies and the tree huggers agree on this point – it is possible for a release of BPA into the contained food, but the amount and the nature of this leakage is the centre of the debate.
On the chemical company side, they hold that the amount is around 3.5 parts per billion. Now that’s a pretty small number – but it’s also the ‘best’ and comes from new bottles (not re-used) and non-heated in any way. After they are re-used and scratched, the amount goes up to 28 ppb but this is not confirmed by the chemical companies, not will they ever release information which says heating or reusing the bottle can lead to an almost x8 increase in BPA leaching. Some studies have show corn oil or ethonal in these bottles pushes that leaching rate to 68ppb, but that is such crap since I can’t think of a reasonable human that would store corn oil or ethonal into a container than re-use it for food purposes… if you wheren’t concerned about the BPA leaching I know I’d be worried about cross contamination which is much more likely to be dangerous. As you can guess the tree huggers sponsored those studies.
The real question is, is BPA a inert and harmless chemical that passes through the human body? No, it’s an endocrine disruptor and levels of BPA from 0.1 to 10 ppb are already more than enough to have effects on humans. What those effects are and their long term consequences mean are still being studied and argued but I think it’s safe to assume it isn’t going to be benign.
Even worse to me though is that BPA is even used to line the cans of food we all use and you know each and every can is heated (for packaging) so there is a very strong possibility some BPA entered the food in the tin can. I think we all eat food from a tin a lot more than water from those colourful bottles. Yet rarely doesn’t anyone make a mention of it.
All that aside, every choice we make is a calculated risk. You can mitigate it with informed choices but at the end you cannot elimiate risk (generally). I still use a cell phone (studies showing it can cause brain tumors to develop) and eat from non-stick pans (though I tend to use cast iron more and more – which leaches something else… iron
but it’s good for you). I don’t think it will kill me, but I try to avoid what I don’t like when I can.
In adults, I don’t know what the long term affects are of BPA ingestion but I do know there are negative effect to a babies developmental progress. It’s even enough for our government to get involved and Health Canada to start a ban on the import/export of baby products (bottles etc) containing BPA (and you know how fast government moves)
There is lots and lots of material you can read, but I see it in a much simpler light.
Pro: I save money not re-buying my baby bottles again
Con:
-I could endanger the development of my child and spend a lot more than a hundred dollars with special classes and medical compilications down the road.
-I will have guilt each time I use the BPA bottles, wondering if I’m doing something wrong.
-I will have to listen to every other person that thinks they know more than I, touting off that I shouldn’t kill my baby.
It turns out to be the best $100 bucks I ever spent. Good nights sleep, no guilt, not danger (yet) and I don’t have to listen to any more people telling me what I already know as a good and informed parent. I just don’t have the energy to explain that I have been tracking this polycarbonate plastic information ever since we got pregnant. I don’t panic, nor make rash choices and truth be told I’m not convinced that BPA is all evil. That said, it’s known to have heightened effects in babies and I’m not willing to find out later. So I make a choice that isn’t about the fear and more about calculated risks. I have nothing to loose to move away from those bottles and products so, not a difficult choice to make.
For anyone looking, I found the Bornfree BPA free bottles at Shoppers Drugmart in Kingston (Bayside). I’d hurry since stores are having big problems keeping them in stock (as with glass or other BPA free products).
