Toxic Legacy

"Toxic Legacy will stand shoulder to shoulder with Rachel Carson’s Silent Spring. [This is] unquestionably, one of the most important books of our time."—David Perlmutter, MD, #1 New York Times bestselling author of Grain Brain and Brain Wash

From an MIT scientist, mounting evidence that the active ingredient in the world’s most commonly used weedkiller is responsible for debilitating chronic diseases, including cancer, liver disease, and more

Glyphosate is the active ingredient in Roundup, the most commonly used weedkiller in the world. Nearly 300 million pounds of glyphosate-based herbicide are sprayed on farms—and food—every year. 

Agrochemical companies claim that glyphosate is safe for humans, animals, and the environment. But emerging scientific research on glyphosate’s deadly disruption of the gut microbiome, its crippling effect on protein synthesis, and its impact on the body’s ability to use and transport sulfur—not to mention several landmark legal cases— tells a very different story.

In Toxic Legacy, senior research scientist Stephanie Seneff, PhD, delivers compelling evidence based on countless published, peer-reviewed studies—all in frank, illuminating, and always accessible language.

Throughout Toxic Legacy readers will discover:

• The uniquely toxic nature of glyphosate

• How glyphosate disrupts the microbiome, leading to gut dysbiosis, autoimmunity, neurodegeneration, and more

• Why we’re seeing a rise in non-alcoholic fatty liver disease, infertility, depression, and anxiety

• Glyphosate’s role in soil degeneration, water contamination, and threats to wildlife and biodiversity

• Important nutritional guidance for conscientious consumers who want to avoid glyphosate-contaminated foods and improve their health

As Rachel Carson did with DDT in the 1960’s, Stephanie Seneff sounds the alarm on glyphosate, giving you guidance on simple, powerful changes you can make right now and essential information you need to protect your health, your family’s health, and the planet on which we all depend.
