The Link Between Your Gut and the Toxicity of Glyphosate
The impact of gut bacteria on your health is becoming increasingly more well-understood and widely known. And here, we see how your gut bacteria once again play a crucial role in explaining why and how glyphosate causes health problems in both animals and humans. The authors explain:
“Glyphosate’s claimed mechanism of action in plants is the disruption of the shikimate pathway, which is involved with the synthesis of the essential aromatic amino acids, phenylalanine, tyrosine, and tryptophan. The currently accepted dogma is that glyphosate is not harmful to humans or to any mammals because the shikimate pathway is absent in all animals.
However, this pathway is present in gut bacteria, which play an important and heretofore largely overlooked role in human physiology through an integrated biosemiotic relationship with the human host. In addition to aiding digestion, the gut microbiota synthesize vitamins, detoxify xenobiotics, and participitate in immune system homeostasis and gastrointestinal tract permeability. Furthermore, dietary factors modulate the microbial composition of the gut.”
As noted in the report, incidences of inflammatory bowel diseases and food allergies have substantially increased over the past decade. According to a recent CDC survey, one in 20 children now suffer from food allergies2 — a 50 percent increase from the late 1990’s. Incidence of eczema and other skin allergies have risen by 69 percent and now affect one in eight kids. Samsel and Seneff argue it is reasonable to suspect that glyphosate’s impact on gut bacteria may be contributing to these diseases and conditions.

Urine samples were collected from volunteers in Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, France, Georgia, Germany, Hungary, Latvia, Macedonia, Malta, Poland, Spain, Switzerland, The Netherlands, and the UK. A total of 80/182 samples tested were found to contain glyphosate. Volunteers were all city-dwellers and included vegetarian and non-vegetarian diets. No two samples were tested from the same household. The samples were analysed by Dr Hoppe at Medical Laboratory Bremen in Germany.
I personally try to steer well away from weedkillers if at all possible.
Correctly applied there is less risk but in real life it often isn't applied anywhere near correctly it's sprayed about with gay abandon and ends up in places it shouldn't. Add to this there is evidence that glyphosates build up in weedkiller resistant GM crops and it's not hard to see where some of the findings about glyphosates in urine come from.
