A new peer-reviewed study released by a group of scientists in Taiwan has revealed an astonishingly strong link between severe depression, cognitive decline and exposure to the world's most used herbicide, glyphosate. The study was fully published on Aug. 22 in the highly respected Elsevier Journal, Environmental Research. It was met with silence by the manufacturers of glyphosate-based herbicides such as Bayer/Monsanto, who produce the infamous weedkiller Roundup. The study authors stated that they: "Conducted analyses on existing data collected from 1532 adults of the 2013"2014 U.S. National Health and Nutrition Examination Survey (NHANES) to explore the possible relationship between glyphosate exposure and cognitive function, depressive symptoms, disability, and neurological medical conditions." The proportion of individuals with detectable levels of glyphosate was 80.4%. The scientists concluded: "Our study provides important evidence of an association between urinary glyphosate levels and adverse neurological outcomes in a representative cohort of U.S. adult population. "Specifically, we observed lower cognitive function scores, greater odds of severe depressive symptoms, and increased risk of serious hearing difficulty in individuals with higher glyphosate exposure." Some other recent independent studies ... suggest that both glyphosate alone and glyphosate-based herbicides such as Roundup are neurotoxins.
