In recent years, concerns have been raised about BPA, Bisphenol A, in plastic bottles and plastic products. BPA is a chemical that has been used for more than 40 years in the manufacture of many hard plastic food containers and bottles. BPA has been found to be a xenoestrogen, an endocrine disruptor that affects hormonal messaging in the body by imitating or enhancing the effects of estrogens. Research and testing is ongoing.
Fortunately, Polar Bottle insulated plastic sport bottles and the new Half Twist Light plastic lifestyle bottles are both made of plastic that does not contain BPA: LDPE #4 and HDPE #2 respectively.
For more information in regard to BPA visit the FDA, the US Department of Health and Human Services and the CDC websites.
