My name is Hector Arreaza, I’m an associate program director and faculty in the Rio Bravo Family Medicine Residency Program. Today my co-host is Cameron Carlisle, who is a 4th-year medical student finishing his last rotation of med school. Welcome, Cameron, please introduce yourself.Arreaza: What are we talking about today, Cameron?Cam: Dr. Arreaza, did you know you’re probably carrying around a chemical in your body that mimics estrogen? In fact, a 2004 CDC study found over 92% of Americans had detectable levels of Bisphenol A (BPA) in their urine. Today’s topic is BPA.BPA is everywhere: receipts, water bottles, canned foods, baby bottles, and even our dental fillings. It’s one of the most ubiquitous endocrine-disrupting chemicals (EDCs), which interferes with the body’s hormone systems. That’s why today’s episode is about making the invisible visible. Our goals for today’s podcast:Break down what BPA isShow how it affects the human bodyExplain how you and your patients can limit exposureEmpower both clinicians and the public with real, practical informationArreaza: Thanks for clarifying BPA today. It seems like we always have to learn about a new carcinogen or toxic substance that we are exposed to. I remember when I was a child, Yellow #5 became very concerning for the general public but it is still being used in our foods. So, it’s good you are talking about this. What Is BPA?Cam: Bisphenol A (BPA) is an industrial chemical used since the 1950s, primarily in polycarbonate plastics and epoxy resins. It makes plastic clear, and is often found in:Water bottlesCanned food liningsBaby bottles (pre-2012)Takeout containersCash register receiptsDental sealantsArreaza: So, I’ve seen the “BPA-free” labels many times, and today I’m glad you are going to shed some light about it.Cam: What’s alarming is that BPA leaches out of these products, especially when exposed to heat, acidity, or repeated use. A Harvard study found that people who drank from plastic bottles for just one week had a 69% increase in urinary BPA levels (Carwile & Michels, 2009).Arreaza: That’s a lot of people 69%.
