A paper published in April 2013 in the physics journal Entropy claims that there is a link between glyphosate and numerous diseases, including autism, Alzheimer’s, obesity, anorexia nervosa, liver disease, reproductive and developmental disorders, and cancer. The authors do not present any new data and develop a hypothesis based on speculation, associating facts and assumptions from different areas of the biomedical sciences in order to create a story that lacks any scientific basis.

The authors, Anthony Samsel and Stephanie Seneff, have strong connections with the anti-GM activist community. Samsel describes himself as helping “those who are victimized by industrial polluters for charity” and is a member of the Union of Concerned Scientists, a well-known anti-GM campaign group. Seneff is affiliated with the Weston Price Association, a foundation that supports organic and biodynamic farming and related activities.

A manuscript about a biological subject matter in a physics journal is highly unusual and lacked the appropriate peer review by relevant experts in the fields of biology and medicine.

The paper collects numerous observations to propose a chain of causation linking glyphosate to these various health issues.  Many of the individual observations made are controversial, incorrect, or poorly established.  None of the disease associations are supported by available toxicology testing, experimentation, or by observations associating glyphosate exposure with these disease outcomes in human populations.

In short, the authors have put forth a series of highly speculative assertions in the absence of any observable and provable associations. Even if one accepts this speculative approach as having scientific value, the authors chose to be very biased and do not consider any alternative hypothetical causalities.
