How to Avoid BPA
Bisphenol A or BPA is a chemical used to make polycarbonates and epoxy resin. Polycarbonates are used in the manufacturing of certain plastic food and beverage containers and epoxy resin is used in the lining of food and beverage cans. BPA mimics estrogen in the body and has been linked to a number of health concerns including cancer, obesity, diabetes, infertility and behavioral issues. France has led the way in banning BPA in all food packaging. The US has banned BPA in baby bottles but has not supported a ban on BPA in food packaging.
AVOIDING BPA
Plastics
BPA is prevalent in plastic food and beverage packaging and storage containers. BPA plastics are easily identified as they are marked with the recycle code 7 or 1. These plastics should be avoided and should never be heated or frozen.
Cans
A 2011 Harvard study showed that volunteers who ate canned soup for lunch daily for 5 days had a 1,221% increase in the BPA level of their urine compared to those that ate fresh soup.
Food stored in BPA lined cans should be avoided. Certain companies such as Eden and Whole Food 365 Brand, to name a few, use BPA free cans. Green Century has published a report card on packaging to help you make the right choice. http://greencentury.com/wp-content/uploads/2013/05/bpareport2010.pdf
Receipts
The Environmental Working Group conducted tests on store receipts in 2010 and found that 40% were coated with BPA. BPA can be absorbed through the skin and transfered to food. There is no way to identify BPA coated receipts, so excess contact should be avoided and they should not be given to children to handle.
Dental Work
BPA is found in some night guards and sports guards. Be sure to ask for a brand that is BPA free. BPA is also present in composite filling material. Dentists should use the “layering” or “sandwiching” technique to insure the product is fully cured which prevents leaching or use BPA free filing materials.
