What started out as a simple post about my water bottle has morphed into so much more! There is so much information out there about the safety of BPA in plastics and it all has me very worried, especially as a mom with kids who drink from plastic sippy cups all day long.
Even more alarming is that more BPA is likely to be released from canned foods than plastic water bottles! This is the first I have heard this, have you? This is bad news for my household. I am domestically challenged, which means we eat a good share of canned food.
Here are some important excerpts from the Enviroblog that opened my eyes a bit. Please visit the site to read the entire article.
“What is BPA?
BPA is a chemical used in the production of certain kinds of plastics, including polycarbonate plastic (like hard, colored water bottles and 5-gallon drinking water coolers) and the lining of most food and beverage cans. BPA can leach from the plastic and into foods and beverages, especially when it’s heated or used for long periods of time. The U.S. Centers for Disease Control found BPA in the bodies of 93 percent of the people they tested, which is especially troubling since the chemical is linked to breast and prostate cancer and neurobehavioral changes in offspring exposed in the womb. It’s a good idea to avoid exposure to BPA whenever possible.
Polycarbonate bottles: As the original post mentioned, studies show low levels of BPA leach out of polycarbonate bottles (like Nalgene and other hard, colored water bottles) at room temperature. More BPA leaches when the bottles are filled with hot liquid. Generally these bottles will be marked with recycling number seven. Polycarbonate is hard, translucent or clear plastic.
These bottles may be marked with the number 7. If you’re going to use a polycarbonate bottle, be aware that it’s likely that higher amounts of BPA leach out of older and damaged bottles. Although we recommend that you avoid drinking from polycarbonate bottles, it’s important to note that your potential exposure to BPA through canned food is considerably higher. As far as we know, #7 drink bottles are rarely recyclable. To be sure, check with your local recycling center.
Other plastic bottles: Don’t reuse single-use plastic drink bottles (PET, or #1 plastic). It’s a good instinct, but bacteria can build up on the inside, and they may leach chemicals too. Drop them in the recycling instead. Bottles made from flexible, cloudy-colored HDPE #2 are considered a safer option if you must have a plastic bottle.
Canned Foods: No matter what brand you use or where you buy your canned food, the cans are almost certainly lined with an epoxy resin that contains BPA. If they didn’t use it, the cans might rust, or you might end up with metal residues in your food. But because of the high temperatures used in the canning process, your potential exposure to BPA from canned food is much higher than your potential exposure from plastic water bottles.
Only one manufacturer that we know of uses non-BPA lining on some of their food cans:
Eden Organic Beans are packed in lead free tin covered steel cans coated with a baked on oleoresinous c-enamel lining that does not contain bisphenol A (BPA). (Oleoresin is a natural mixture of an oil and a resin extracted from various plants, such as pine or balsam fir). These cans cost 13.77 percent more than the industry standard cans that do contain BPA. This costs Eden $300,000 more a year. To our knowledge Eden is the only U.S. company that uses this custom made BPA-free can.”
Enviroblog also offers tips to minimize your BPA exposure:
Limit canned foods. BPA leaches into canned food from the lining. When possible, and especially when pregnant or breastfeeding, limit the amount of canned food your family eats. Particularly avoid canned soup, pasta, and infant formula.
Avoid polycarbonate plastic. Hard, translucent plastic marked #7 is probably polycarbonate, which leaches BPA, especially when heated. Ditch your polycarbonate water bottles in favor of a stainless steel bottle. Don’t microwave plastic — use ceramic or glass instead.
If you’re formula feeding your infant, consider using powdered formulas packaged in non-steel cans. Also, choose baby bottles made from glass or specially-marked plastics that don’t leach BPA (like polypropylene or polyethylene).
I have a feeling this is just the beginning of it all. First it was my kids’ toys getting recalled and now all of our cups/cans might be toxic. I’m about ready to pack up and move to a grass hut on a remote island somewhere. I’m bringing my running shoes though, I’m pretty sure they will be on the safe list!
