It seems like every few months a new study comes out about Roundup and its active ingredient, glyphosate. In February 2019 the University of Washington published a paper that found that glyphosate can increase the risk of cancer by 41%. The following month a study was published finding that glyphosate was found in 19 out of 20 beer and wine samples. Now we’re hearing that glyphosate is being linked to Parkinson’s disease. If you or a loved one has used or uses this herbicide, here’s what you need to know concerning your health and glyphosate.

Key Points from the Parkinson’s Study

There are the important things that you should know from this study:

  • It was conducted by a research team from the University of Washington.
  • Glyphosate is allegedly linked to the deaths of Parkinson’s patients under the age of 75 who lived in agricultural areas.
  • Residents who lived within a thousand meters of an area sprayed with glyphosate were nearly one-third more likely to die from Parkinson’s before the age 75.
  • In the agricultural county where the study was conducted, premature death rates were the highest in the state. Furthermore, a large portion of the deaths occurred just half a mile from where glyphosate was being applied.
  • Pest control chemicals such as atrazine and diazinon didn’t have the same effects as glyphosate.

Additional Studies Linking Glyphosate to Parkinson’s

While this UW research may be the latest study to be published linking glyphosate to Parkinson’s, it certainly isn’t the only one. Here are a few more findings:

  • 2003 – A study conducted by health care agency Kaiser Permanente found that before Roundup became popularized, Parkinson’s was rare among farmers and agricultural workers. By 1994-95 (20 years after Roundup was put on the market), farmers and farm workers at non-organic farms reported having Parkinson’s in disproportionate numbers as compared to other occupations. A 2011 study in France came to the same conclusion that agricultural workers were at a higher risk for being diagnosed with Parkinson’s.
  • 2012 – A team from the Department of Neurology & Institute of Neurology, Ruijin Hospital, China theorized how glyphosate can cause Parkinson’s through damaging brain cells: “glyphosate [can] induce cell death via autophagy pathways in addition to activating apoptotic pathways.”
  • 2014 – In a study conducted in Brazil, researchers observed that, “glyphosate induced both apoptotic and autophagic cell death in neuronal differentiated PC12 cells, providing a link between glyphosate and Parkinson’s disease.”

Roundup has been scientifically linked to cancer (brain, breast and non Hodgkin lymphoma), autism, infertility, birth defects, kidney disease, celiac disease and gluten intolerance, respiratory problems, and many more chronic conditions. Even with piles of studies showing the dangers of glyphosate and Roundup, Bayer refuses to admit that their herbicide is hazardous and refuses to even put a warning on the label. You could continue to use Roundup, but do you really think it’s worth the risk?
