endocrine disruptors

resourceinsights |  Several years ago over lunch a medical researcher I know told me that industrial chemicals were disrupting the human endocrine system leading to widespread obesity and diabetes. He said his research had revealed an important cause--the decline in the production of testosterone in both men and women (yes, women produce a little testosterone) due to this disruption. When this deficiency was reversed, patients experienced significant improvement in both obesity and diabetes.

That's not all. He explained that most people believe that poor diet and little exercise are the central cause of obesity and diabetes. No doubt poor diet and exercise are important contributing factors. But when the body's signaling system fails to indicate when it has had enough to eat, it's hard for most people to recognize that they need to stop eating. How many of us know people who say that they are hungry all the time? A normal human being with a normal endocrine system should not feel "hungry all the time."

The link between what has become a sweeping twin epidemic and man-made chemicals is getting wider notice these days. But the link between endocrine disruption, obesity and diabetes is still absent from popular medical accounts such as those found on WebMD for obesity or on official sites such as that of the World Health Organization.

Endocrine disruption has also been linked to cancer, reproductive failure, neurological disorders and developmental problems in fetuses, problems that can lead to illness later in life. In fact, industrial chemicals known to disrupt endocrine function are found in humans and animals worldwide.

The subject of endocrine disruption first burst into the public mind with the publication of Our Stolen Future in 1996 by three scientific researchers. They sought to make the issue more accessible to the public in order to galvanize action.

A few companies have voluntarily eliminated a known disruptor from the linings of food cans and in plastic bottles and containers. But the disruptor, bisphenol A, commonly referred to as BPA, while banned from baby bottles, continues to be used widely.
