This paper presents an exhaustive review of the toxic effects of the herbicide, glyphosate, the active ingredient in Roundup�, in humans, and demonstrates how glyphosate�s adverse effects on the gut microbiota, in conjunction with its established ability to inhibit the activity of cytochrome P450
enzymes, and its likely impairment of sulfate transport, can remarkably explain a great number of the diseases and conditions that are prevalent in the modern industrialized world. Its effects are insidious, because the long-term effects are often not immediately apparent. The pathologies to which glyphosate could plausibly contribute, through its known biosemiotic effects, include inflammatory bowel disease,
obesity, depression, ADHD, autism, Alzheimer�s disease, Parkinson�s disease, ALS, multiple sclerosis, cancer, cachexia, infertility, and developmental malformations. Glyphosate works synergistically with other factors, such as insufficient sun exposure, dietary deficiencies in critical nutrients such as sulfur
and zinc, and synergistic exposure to other xenobiotics whose detoxification is impaired by glyphosate.

Given the known toxic effects of glyphosate reviewed here and the plausibility that they are negatively impacting health worldwide, it is imperative for more independent research to take place to validate the ideas presented here, and to take immediate action, if they are verified, to drastically curtail the use of glyphosate in agriculture. Glyphosate is likely to be pervasive in our food supply, and, contrary to being essentially nontoxic, it may in fact be the most biologically disruptive chemical in our environment.
