Why is BPA a threat? It belongs to a large family of chemicals described as endocrine disruptors. The endocrine system is the body’s hormonal messaging system, so if it gets disrupted—if messages are altered—the impact on our health can be significant. BPA binds to receptors on cells that the body’s natural hormones use to regulate physiological function. In doing so, BPA displaces the natural hormones—basically, knocks them off the receptors and takes their place—and thereby sends different messages to the cells.
