BPA is used as a monomer to manufacture epoxy, polyester-styrene, and polycarbonate resins used in most plastics; however, for decades scientists have known that BPA is an endocrine disruptor, which can harm the developmental, reproductive, and other systems in mammals. An endocrine disruptor is a substance that “interferes with the synthesis, secretion, transport, binding, action, or elimination of natural hormones in the body that are responsible for the maintenance of homeostasis (normal cell metabolism), reproduction, development, and/or behavior” (Crisp et al. 1998). In short, BPA mimics the naturally occurring hormone estrogen.
Too much estrogen in the body can lead to a range of health concerns including, but no limited to:
- multiple types of cancer
- thyroid problems
- developmental issues
