(NaturalNews) According to the National Institute of Neurological Disorders and Stroke, most researchers believe exposure to some kind of toxin or toxins in the environment triggers the development of Parkinson’s disease (PD) — the degenerative disorder of the central nervous system that impairs motor skills (including walking), speech and other functions.
Pesticides have long been on the list of possible suspects as a PD-causing toxin. But a new study just published in the American Journal of Epidemiology by University of California at Los Angeles (UCLA) scientists appears to be the “smoking gun” that places pesticides at the top of that list.
They found that exposure to a combination of two widely used pesticides increased the risk of Parkinson’s disease by an incredible 75 percent.
In previous animal studies and cell cultures, researchers have shown pesticides spark a neurodegenerative process that leads to Parkinson’s disease. The UCLA scientists, however, are the first to provide evidence for a similar process in humans.
They came up with their alarming results by analyzing an epidemiological study of Central Valley, California, residents. The region is one of the nation’s top food-growing regions and crops like potatoes, dry beans and tomatoes have long been routinely sprayed with fungicides, herbicides and pesticides.
