Bisphenol A (BPA) has been the topic of discussion for many years now with the concern of this chemical in plastic water bottles. It’s now show to be in the lining of canned goods which are heated during the canning process at 250°.
“According to the Environmental Working Group, cans are the primary source of human exposure to the chemical. (Most metal food cans have plastic linings that prevent spoilage but are rich in bisphenol A.)” writes Adam Voiland of http://health.usnews.com

Q: What is BPA?
A: Bisphenol A (BPA) is a chemical produced in large quantities for use primarily in the production of polycarbonate plastics and epoxy resins.
Q: How does BPA get into the body?
A: The primary source of exposure to BPA for most people is through the diet. While air, dust, and water are other possible sources of exposure, BPA in food and beverages accounts for the majority of daily human exposure.
Bisphenol A can leach into food from the protective internal epoxy resin coatings of canned foods and from consumer products such as polycarbonate tableware, food storage containers, water bottles, and baby bottles. The degree to which BPA leaches from polycarbonate bottles into liquid may depend more on the temperature of the liquid or bottle, than the age of the container. BPA can also be found in breast milk.
Q: If I am concerned, what can I do to prevent exposure to BPA?
A: Some animal studies suggest that infants and children may be the most vulnerable to the effects of BPA. Parents and caregivers, can make the personal choice to reduce exposures of their infants and children to BPA:
- Don’t microwave polycarbonate plastic food containers. Polycarbonate is strong and durable, but over time it may break down from over use at high temperatures.
- Polycarbonate containers that contain BPA usually have a #7 on the bottom
- Reduce your use of canned foods.
- When possible, opt for glass, porcelain or stainless steel containers, particularly for hot food or liquids.
- Use baby bottles that are BPA free.
Education is the key to anything. We count on others (experts) to know what’s best for us, but in all fairness, people are fallible; they have bias and motives as we all do. Although the FDA and corporations involved know plastic is dangerous for human consumption, they are heavily invested and not about to walk away.
You do have a choice. You can choose to educate yourself, research what you hear and make the decision for yourself. Make small changes such as throwing out plastic containers and using glass instead. Cook only what you need, thus eliminating left overs and don’t purchase bottled water.
If you choose to make the switch from plastic, share what changes you are making. If you have tips to getting through the switch easier, please pass them along. Plastic has become a staple for many and it will be difficult to let go. Any suggestions are welcome!
