The worrisome chemicals, mostly or entirely man-made, are in the environment, water, food or food packaging. From MNT:
“The Endocrine Society’s Second Scientific Statement on Endocrine-Disrupting Chemicals (EDC-2) was developed “to bridge [the] gap between basic, translational, clinical, and public health knowledge, EDCs,” according to its lead author.
“About 10 years ago, the Endocrine Society began working with a group of scientists and physicians to consider the evidence that EDCs are a significant concern for human health,” Andrea C. Gore, PhD, of the University of Texas Austin, told MedPage Today. “In 2009, I led a group of authors in writing a review paper, which led to the Society’s first Scientific Statement. Five years later, the evidence linking EDCs to chronic endocrine diseases involving reproductive, thyroid, cardiovascular, type 2 diabetes mellitus, obesity, and even hormone-sensitive cancers, had mounted. We wrote EDC-2 to review this evidence based on animal models and epidemiology, and the resulting paper allows us to draw much stronger conclusions about concerns about EDC exposures.”
