“BPA: A New Scare”
Bisphenol-A (BPA) is an antioxidant that is found in the lining of canned foods, cash register receipts, dental fillings, some plastics and polycarbonate bottles marked with the number 7. BPA is best known as a hardening agent in plastic bottles and used to line the inside of metal cans. Scientific studies have linked BPA at lower levels than those found in the Harvard study to cardiovascular disease, diabetes and obesity in humans. More than 1 million pounds of BPA are released into the environment each year and most Americans have BPA in their urine. Early in 2011, the European Union banned the use of BPA in the manufacture of baby bottles and its use in infant food containers is also restricted in Canada as well as 10 US states. The focus has been on the ingestion of BPA by children in baby bottles or in sippy cups, but attention is now being turned to unsafe adult ingestion of BPA, especially in canned goods.
