Autism is a complex neurodevelopmental disorder whose incidence has been rising dramatically in the past two decades, in step with the dramatic rise in the use of glyphosate (the active ingredient in the pervasive herbicide Roundup) on core food crops [1, 2]. While correlation does not necessarily mean causation, there are multiple mechanisms by which glyphosate’s disruption of human biology, and the biology of the gut microbiome, could cause many of the observed symptoms and biological metrics associated with autism [3, 4].
