What Is Bisphenol-A Or BPA?

By Rachel Lacourciere, edHelperBaby

  What Is Bisphenol-A Or BPA?
           Bisphenol-A (abbreviated BPA) is a chemical building block that is used to make polycarbonate plastics-plastics which are usually labeled with the number 7.  BPA is also used to produce epoxy resins that, among many uses, function as protective liners in metal food cans.  The highest levels of BPA have been found in cans of chicken soup, ravioli, and infant formula (pre-mixed, not powdered).  It is important to realize that BPA has been extensively studied and used in consumer products for over 40 years.  However, recently BPA has been linked to causing behavioral changes in babies as well as the early onset of puberty in girls.       

       While these latest studies need to be tested further, some parents feel it is best to switch to BPA-free products for themselves and their babies until more conclusive evidence is collected.  In fact, many plastic and metal container companies now openly publicize which of their products are BPA-free, making it easier on parents who are looking to replace the containers they currently own.  Furthermore, concerned mothers should limit their canned food consumption until more definitive research has been done on the possible effect, (if any), of BPA on the growing fetus.       

       Take the time to check with your regular prenatal doctor if you have additional questions about BPA while you are pregnant.

   

  Which Plastic And Metal Containers Should I Be Concerned About In My Own Home?
           For the most part, the concern over BPA is currently with growing babies and children.  Since adults have matured, any adverse effect from the consumption of BPA on adult hormones is assumed to be minimal at this point.  However, since no real research has been conducted on the effect,(if any), of BPA on the growing fetus, some parents may feel most comfortable stopping the use of plastics and metals that contain BPA.       

       Parents who feel this way should eliminate plastics labeled with the number 7.  These plastics are often transparent in color and firm to the touch, making them difficult to be bent and ideal as water bottles, baby bottles, sippy cups, and food storage containers.  If you would still like to use plastic containers, look for manufacturers who advertise BPA-free alternative plastics.  Additionally, plastics labeled with the numbers 1, 2, and 4 are considered safer choices and do not contain BPA.   It is also recommended that as any plastic container becomes worn-out from overuse, it should be replaced to avoid any possibility that the chemicals will leach out of the plastic as it breaks down over time.       

       Moreover, keep in mind that metal drinking containers contain a protective lining that contains BPA.  Therefore, concerned parents should make sure they choose stainless steel bottles that do not contain a plastic liner and again, look for metal products that are labeled BPA-free.
