Toxins Effect Us for Generations
Research from Washington State University, Case Western Reserve University School of Medicine, University of Toronto Medical School and the University of Texas have confirmed that ones environment not only affects our genetic information (epigenetics): Exposure to toxins will produce metabolic changes, physiology changes, behavioral changes and cognitive changes two and three generations later.
University of Toronto and Case Western Reserve University researchers have determined that environmental stress will affect ones genes for several generations after the stressor. This precipitated from epidemiological research several decades ago showing that periods of starvation or famine caused metabolic affects in farming families two and three generations later. Now it appears that many other types of stressors, including environmental stress and toxic stress, can affect a family several generations later.
This February, a study from Washington State University was published showing that dioxin, plastic compounds like bisphenol A and phthalates, and JP8 – a jet fuel – will produce DNA damage that affects metabolism in rats multiple generations after the initial exposure.
A new study from the University of Texas confirmed this finding by discovering that vinclozolin – a fungicide – also produced DNA damage that affected multiple generations of rats. The research showed that several generations later showed changes in “physiology, behavior, metabolic activity, and transcriptome in discrete brain nuclei in descendant males, causing them to respond differently to chronic restraint stress.”
These results are consistent with epidemiology research that shows transgenerational effects caused by environmental and dietary factors can produce diseases such as cancer, heart disease and diabetes several generations later.
Now we can add brain damage, behavioral problems and cognitive issues to this list.
The bottom line is that these epigenetic environmental stressors are toxins produced by our chemical industrial complex. Our choices are clear: Rethinking our (so far) irresponsible widespread use of synthetic chemicals, or face a widespread breakdown of health among our grandchildren, their children and successive generations – if humans survive that far.
