New study reveals that thyroid-disrupting BPA is found in some canned goods

Recent research has linked bisphenol A (BPA) to a range of health ailments including heart disease, cancers and thyroid disruption. Yet a new study shows that there are traces of the chemical in a wide variety of canned foods from supermarket shelves, as well as in products that are packaged in plastic and in one sample from the deli counter, Discovery News reports.

The study suggests that food - especially canned goods - might be one major source of ingested BPA. The amounts of BPA found in the food samples were far lower than recommended limits, but they were still high, according to lead researcher Arnold Schecter, a public health physician at the University of Texas School of Public Health in Dallas.

Humans get exposed to BPA from a number of sources, including cash register receipts, according to recent research. Some scientists think that recommended limits should be five times lower than they are now.

In 2009 The Endocrine Society released a scientific statement expressing concern over current human exposure to BPA. According to the statement, endocrine-disrupting chemicals include “substances in our environment, food and consumer products that interfere with hormone biosynthesis, metabolism or action resulting in a deviation from normal homeostatic control or reproduction.”
