Bisphenol A (BPA) is an organic compound used in the creation of many plastics, the most common of which is polycarbonate. Polycarbonate plastics are used widely throughout many industries and have the beneficial characteristics of being a shatter resistant clear plastic. Because of this, BPA is often found in plastic drinking bottles, baby bottles, and sippy cups.

So why should you be concerned about BPA?
BPA has been found to leach into liquids from plastic, plactic lined metal cans, and plastic bottles. Washing the plastics with harsh detergents and filling them with warm liquids increases the risk. A prime example of this is heating a baby bottle on the stove top or in a microwave.

BPA mimics estrogen and can thus can disrupt hormonal development in humans. The exact long term human effects are still being studied at this time and an outright ban of the use of BPA has not yet been warranted in the US. However, this is of extreme concern for developing fetus’s and young children using baby bottles and sippy cups containing BPA.
