‘Toxic Legacy’ — How Glyphosate Destroys Your Health
Stephanie Seneff, Ph.D., a senior research scientist at MIT, has published a new book, “Toxic Legacy: How the Weedkiller Glyphosate Is Destroying Our Health and the Environment” — without doubt the best book ever written about glyphosate, the active ingredient in Roundup and many other toxic herbicides.
In this book, which has been a labor of love for the past decade, Seneff explains how and why it’s so important to avoid it if you care about your health and the health of your family.
“It’s been a decade of learning everything I could about glyphosate,” Seneff says. “When I first heard about it I basically dropped everything else I was doing because I was so confident that I had found the answer to the autism epidemic. That was the thing I was looking for. Back in 2012, I heard a two-hour lecture by Don Huber, and it changed my focus entirely.
I already understood the symptoms of autism, a very complex disease — lots of gut problems and mineral issues — and it all came together with his lecture. Overnight I just started poring over all the papers I could find.
Shortly after that I found Séralini’s paper,1 which had not yet been retracted at that time. It was later republished, the paper by Séralini, a French toxicologist who had shown that very low doses of glyphosate over the lifespan of a rat could cause a lot of damage.
He pointed out that after three months, everything looked good, so it’s a slow kill. This is one thing I emphasize in my book. Glyphosate is subtle, and that’s really a huge problem because people don’t [make the connection]. We have diabetes, obesity, autism, Alzheimer’s. It’s a long, long list, all the gut problems.
The microbes are being very much disturbed by the chronic poisoning with glyphosate, and then the gut becomes a central starting point for many diseases, including neurological diseases and arthritis. So, you see that disruption of the gut, and glyphosate can cause exactly the things that we’re seeing.”
Glyphosate Contamination in Common Products
Before delving into glyphosate, Seneff spent five years focusing on the potential toxicities of vaccines. She still believes vaccines can play a role in the chronic diseases we’re seeing, including autism.
However, glyphosate may actually play a more significant role. Seneff believes it contributes to and worsens damage caused by vaccines, in part because it binds very efficiently to aluminum used as an adjuvant in certain vaccines. It likely binds strongly to many other toxic metals as well.
The theory is that, by being wrapped up with glyphosate molecules, the metals can more easily penetrate various barriers in your body. This is because glyphosate causes these barriers, such as your intestinal barrier and your blood-brain-barrier, to become more porous. And, as leaky gut or leaky brain set in, the toxic metals are shuttled across, along with the glyphosate.
Seneff also hypothesizes that, since glyphosate is found in many vegetable-based fats, such as canola and soybean oil, studies comparing the health effects of fats may be compromised since they never consider the effects of glyphosate. Interestingly, while not fat-soluble, glyphosate can still enter fats (and is found in the vegetable oils just mentioned).
Samsel suspects glyphosate acts as a phosphate analog, because it has a phosphonate unit, and fats have phosphates (phospholipids). This is something he’s investigating right now, so eventually, we may learn more about that mechanism.
