What does BPA do to us? We still don't really know, since we don't have definitive studies of its effects in people yet. The U.S. Food and Drug Administration used to say that BPA was safe. But in 2010 the agency altered its position. The FDA maintains that studies using standardized toxicity tests have shown BPA to be safe at the current low levels of human exposure. But based on other evidence — largely from animal studies — the FDA expressed “some concern” about the potential effects of BPA on the brain, behavior, and prostate glands in fetuses, infants, and young children.
Bisphenol A (BPA) is a chemical that is used in a wide variety of consumer products, such as resins used to line metal food and beverage containers, thermal paper store receipts, and dental composites. BPA exhibits hormone-like properties, and exposure of fetuses, infants, children or adults to the chemical has been shown to cause numerous abnormalities, including cancer, as well as reproductive, immune and brain-behavior problems in rodents.
Now, researchers at the University of Missouri have determined that daily exposure to very low concentrations of BPA by pregnant females also can cause fetal abnormalities in primates.
BPA is an endocrine disrupting chemical that has been demonstrated to alter signaling mechanisms involving estrogen, androgen and thyroid hormones, said Frederick vom Saal, Curators Professor of Biological Sciences in the College of Arts and Science at MU. Previous studies in rodents have demonstrated that maternal exposure to very low doses of BPA can significantly alter …
Trying to eliminate BPA from your child's life is probably impossible. But limiting your child's exposure — and your own — is possible. It doesn't even have to be hard. Find products that are BPA-free. It isn't as hard as it once was. Many brands of bottles, sippy cups, and other tableware prominently advertise that they are BPA-free. Look for infant formula that is BPA-free. Many brands no longer contain BPA in the can. If a brand does have BPA in the lining, some experts recommend powdered formula over liquid. Liquid is more likely to absorb BPA from the lining. Choose non-plastic containers for food. Containers made of glass, porcelain, or stainless steel do not contain BPA. Do not heat plastic that could contain BPA. Never use plastic in the microwave, since heat can cause BPA to leach out. For the same reason, never pour boiling water into a plastic bottle when making formula. Hand-wash plastic bottles, cups, and plates. Throw out any plastic products — like bottles or sippy cups — that are chipped or cracked. They can harbor germs. If they also have BPA, it's more likely to leach into food. Use fewer canned foods and more fresh or frozen. Many canned foods still contain BPA in their linings. Avoid plastics with a 3 or a 7 recycle code on the bottom. These plastics might contain BPA. Other types of numbered plastic are much less likely to have BPA in them.
