‘Systemic Catastrophe’: Glyphosate Is a Slow Kill

‘Systemic Catastrophe’: Glyphosate Is a Slow Kill. By Marina Zhang.

Glyphosate was first used in Roundup, a herbicide developed by Monsanto in 1974.

Upon its release, Monsanto marketed glyphosate as harmless to humans and other mammals. The company reasoned that glyphosate kills weed by disrupting the shikimate pathway, which is not present in animals and therefore would not be harmful.

“However, this pathway is present in gut bacteria,” [Seneff, a senior researcher from MIT] wrote in her first study on glyphosate.

Recent research has revealed that human bodies have more bacteria than human cells, and our gut microorganisms play very important roles in maintaining our health. …

Bowel disorders, autism, allergies:

Knowing that glyphosate may be able to influence pathways in the gut bacteria and cause disturbances, Seneff reasoned that the yearly increase in bowel disorders, autism (which is highly correlated with impaired gut bacteria), allergies, and many other diseases may all be due to the diet we eat; a diet containing foods high in glyphosate.

She found yearly increases in disease cases, such as diabetes and various cancers, can be directly correlated with an increase in glyphosate use. …

Lifespan, cancers, organ damage:

Glyphosate is implicated in many cancers. One of the earliest glyphosate studies by Dr. Gilles-Éric Séralini, a French molecular biologist and friend of Seneff, showed that low doses of Roundup exposure over a lifetime lead to shorter lifespans and organ damage in rats.

Further, laboratory studies on human cells and sea urchin embryos have also shown that glyphosate caused DNA breakage, which is a major factor in cancer progression.

Even Monsanto’s earlier papers showed organ damage and tumor growth in rats, though these results were not given much attention after the company submitted new studies showing no significant health impacts. …

Seneff is also highly confident that glyphosate’s disturbance to the gut is what causes autism, coeliac, and other allergies and behavioral problems, with some of the people around her sharing stories of improvements in their children’s behavioral and asthma problems after they switched their children’s diet to organic foods. …

Obesity and diabetes:

The biggest concern and speculation Seneff and Samsel have made was that glyphosate may be incorporated into human proteins, the very building blocks of our cells. … Seneff’s studies speculate that glyphosate is structurally similar to an amino acid named glycine, and therefore cells may mistakenly take up glyphosate and build it into proteins, thinking that it is glycine. …



Glycine is present in proteins that regulate fat as well as insulin. If glyphosate replaced glycine in these proteins, these proteins will become impaired and lose their function in regulating fat and blood glucose, leaving the body open to metabolic disorders including obesity and diabetes.

How to reduce exposure:

To reduce glyphosate exposure, Seneff recommends eating organic food and drinking filtered water.

Since glyphosate is used to spray weeds, many plants such as corn, soy, canola, sugar beets, cotton and alfalfa are genetically modified so that they would not be harmed by glyphosate. This has significantly increased glyphosate content in plants with farmers also spraying the plants as opposed to only spraying the weeds.

Seneff said the substance is pervasive, and despite all her efforts to avoid exposure to glyphosate, she still tested positive for the substance when she did testing at home.

That could explain a lot. Look at tv and movies made before 1980 — everyone is skinnier and healthier looking.
