Modern medicine accidentally deleted a biological partner, and our health has been unraveling ever since. According to data presented on Radiolab, a two-year Australian clinical trial led by Dr. Paul Jackerman gave live hookworms to pre-diabetic patients. The results were startling: participants saw significant reductions in blood glucose levels and lost weight, while the placebo group continued to decline. Some patients were effectively cured of their pre-diabetic status. Almost every participant opted to keep their worms after the trial ended.
The trial adds concrete evidence to a hypothesis that has been circulating in niche research circles: that the eradication of hookworms triggered the modern epidemic of autoimmune and metabolic diseases. Rockefeller's 1908 commission targeted the parasite to fix what was perceived as the 'lazy' South, linking anemia to sandy loam soils. Researchers built sandbox experiments showing larvae could crawl four feet from infected stool, leading to the adoption of outhouses dug six feet deep.

The campaign successfully traded historical lethargy for modern asthma, allergies, and Crohn's disease. Dr. Paul Jackerman argues that without these co-evolved parasites, which secrete immune-quieting proteins he calls 'lullaby cells,' our internal defenses go rogue. Dixon Despommier notes that improved sanitation, while reducing diseases like salmonella and cholera, also removed this key immune regulator.
Practical application faces a massive regulatory impasse. Jasper Lawrence once ran a business mailing hookworms to desperate patients - he was inspired by research showing asthma was 50% less likely in people with infections - before the FDA forced him to flee the country. The therapy's raw material is human waste, requiring human 'worm farms' to produce larvae. Every dose is slightly different, making standardization and traditional FDA approval pathways nearly impossible.
Researchers are now pivoting to a synthetic solution: identifying the specific proteins worms secrete and manufacturing them in a lab. Until that pill arrives, patients remain stuck between illegal self-infection and waiting for a decade of pharmaceutical development. The data from Jackerman's trial, however, suggests the biological path already works.
"You cannot easily culture hookworms in a lab; you need human 'worm farms' to produce the larvae."
