Bisphenol A (BPA) is an organic compound used to make polycarbonate plastic and epoxy resins, along with other applications. Polycarbonate plastic, which is clear and nearly shatter-proof, is used to make a variety of common products including baby and water bottles, sports equipment, medical and dental devices, dental fillings and sealants, eyeglass lenses, CDs and DVDs, and household electronics. Bisphenol A is a preferred color developer in carbonless copy paper and thermal paper with the most common public exposure coming from some thermal point of sale receipt paper. Epoxy resins containing bisphenol A are used as coatings on the inside of almost all food and beverage cans.
BPA is one of many “persistent organic pollutants” that is known to cause harm. It has been known to be estrogenic since the mid 1930s and as such, wreaks havoc within our body as it is a foreign molecule. An impostor with bad side effects.
A 2010 report from the United States Food and Drug Administration (FDA) raised concerns regarding exposure of fetuses, infants and young children to BPA. Us adults should worry too even though we have more mass so initially amounts are less concentrated. In September 2010, Canada became the first country to declare BPA a toxic substance. By all rights, we should follow.
As you can see, BPA is ubiquitous in our environment…meaning it is everywhere. BPA creates a toxicity for us and our livers. As a foreign molecule, it must be disposed of. But given the toxic load we now live in (air, water, highly sprayed food along with more processed food so less nutrition overall) and the high levels of stress, violence, radiation (cell phones, microwaves..) and the low levels of exercise we get, BPA can accumulate within our cells and disturb metabolism. The outcome of this is chronic disease… meaning any disease which took time to acquire. Our daily lifestyle choices, long-term.
In Agouti mice, exposure of the mother to BPA made offspring obese, hyperphagic (hungry), and their color was different than that of their non-BPA siblings. They were more prone to type 2 diabetes, had insulin resistance, etc. Exposure to BPA changed their gene expression.
In humans, we know that it accumulates and causes hyperplasia (cancer) and since it is estrogen-like, it is linked with many, many reproductive disorders as well. I was taught in graduate school, in the early 2000’s, that researchers couldn’t get breast cancer cells to stop dividing until they used glass Petri dishes in lieu of plastic Petri dishes. Meaning, the plastic Petri dish FED the cancer cells.
If our lifestyle causes chronic disease, because of daily choices over and over, our lifestyle (not drugs and surgery) should be used as a first-line therapy to treat disease.
If you are picking up what I’m laying down, you see that our world is toxic and this is just one example. All chronic diseases are on the rise. We need to support our body’s inherent ability to detoxify.
