Physician and researcher Zach Bush joins Joe Rogan to argue that glyphosate, introduced commercially in 1976, is the root cause of a cascading chronic disease epidemic spanning allergies, autoimmune conditions, neurological disorders, and cancer, with global application now running between 3 billion and 4 billion pounds annually.
Zach Bush argues that science has historically treated the human body as an isolated system rather than part of a living ecosystem, and that 150 years of office culture, performance-based reward systems, and standardized education have trained people to behave like machines. Drawing on his experience as a hospice physician who has sat with thousands of dying patients, he says not one ever recalled a day spent in an office as meaningful, and that dying patients frequently recognize their lives were perfect regardless of conventional success metrics. He estimates roughly 10 percent of hospice patients do not die and are discharged to live differently, and frames the current global moment as a hospice event for the species, with humanity in its current form having existed approximately 300,000 years and having a few decades remaining in that form.
Bush describes humans as a keystone species whose genuine engagement with nature increases biodiversity. He cites the Amazon jungle as a manmade food forest designed by hundreds of nations over 40,000 years, now desertifying as indigenous peoples are displaced. The Ochuwa tribe, located in the sacred headwaters of the Amazon, made first contact with industrialized society in 1996 because they had begun dreaming the end of the world and believed they needed to reconnect what they called their little brothers to nature. Their first cultural disruption was boxed apple juice containing high fructose corn syrup introduced through missionary schools, and within 30 years they consider themselves impoverished and are seeking motors, artificial food, and smartphones. Bush explains that high fructose corn syrup is a mirror image molecule of natural fructose that the liver cannot process as a carbohydrate, converting it instead into inflammatory triglycerides that drive cardiovascular disease, brain inflammation, depression, and anxiety, and that it acts on the frontal lobe similarly to cocaine.
Bush traces modern chronic disease directly to glyphosate, introduced to the food system in 1976, with obesity rising roughly four years later. Glyphosate functions as an antibiotic that kills bacteria in soil and inside cells, with mitochondria being the primary intracellular target. In laboratory conditions it collapses ATP production within 30 minutes at one part per million, with effects observed at concentrations as low as 10 parts per billion. Bush maps a sequential disease timeline beginning with widespread allergies in the 1990s, followed by a gluten sensitivity wave around 1992 driven by gliadin interacting synergistically with glyphosate, then autoimmune disease, then a logarithmic rise in neurological conditions including ADHD, autism, Alzheimer's, Parkinson's, MS, and ALS, then a cancer epidemic beginning in the early 2000s. He attributes this cancer wave to decreased metabolic life force rather than increased carcinogen exposure. Global glyphosate application today runs between 3 billion and 4 billion pounds per year. He connects the same mitochondrial energy collapse to fertility decline, noting the United States fertility rate is approximately 1.6 against a replacement level of 2.1, with 110 countries now below replacement. He argues insufficient mitochondrial energy around 90 days of embryologic development prevents biological polarization toward male or female, producing gender dysregulation, and projects one in three children will have autism by 2035 if the current trajectory continues.
Bush and Rogan discussed the Rockefeller-funded Flexner Report of 1910, which demonized herbal medicine and promoted small carbon molecule pharmaceuticals, and the post-World War II glut of oil that incentivized converting carbon molecules into high-value drugs and agricultural chemicals. Monsanto produced Agent Orange, used to defoliate the Ho Chi Minh trail, and later acquired a glyphosate patent in 1974, repatenting it as Roundup in 1976. Bush argues that glyphosate has not been banned because the food supply and the medical system both now depend on it, the latter because medical revenue depends on the chronic disease that chemical food produces.
Bush argues that a human cell losing connection with its surrounding environment immediately takes on the traits of a cancer cell, and extends this to human behavior, describing the sociopath as the biological equivalent of a cancer cell. When isolated cancer cells were reconnected and nourished rather than poisoned, they either repaired and rejoined the greater system or underwent apoptosis. He cites Chernobyl voles that have eaten radioactive soil for roughly 50 years, are measurably radioactive, yet show no deformities or fertility decline, attributing this to their microbiome up-regulating pseudomonas bacteria that digest radioactive material and repair tissue faster than injury accumulates. His core principle is that as long as an organism's rate of repair exceeds its rate of injury, it never develops disease.
Bush describes autism as a neurological development in which individuals function as wide-open antennas who feel too much and lack the cognitive gating that allows neurotypical people to absorb abstract belief systems. He spent two years treating mothers of severely autistic children using Emotion Code Therapy rather than the children directly, and found children improved before receiving any direct treatment, concluding that autism expresses a field effect rather than a personal disorder. He frames autistic neurology as minds still connected to nature and draws parallels between autistic individuals and indigenous elders who share experiential traits including what he describes as telepathic communication with forest systems. He predicts the antibiotic era is ending and will be replaced by a biological renaissance, comparing the coming shift to the historical Renaissance as a parametric explosion of creativity coinciding with a reopening of the human antenna to information.
