Forks Over Knives shows people whose diabetes or pre-diabetes was reversed after they went on — and stuck to — a completely plant-based diet. This article by Tom Philpott of Mother Jones wonders if pesticides might play a role.
A new peer-reviewed study published in the journal Diabetes Care found a strong link between diabetes onset and blood levels of a group of harsh industrial chemicals charmingly known as “persistent organic pollutants” (POPs), most of which have been banned in the United States for years but still end up in our food (hence the “persistent” bit—they degrade very slowly).
The ones with the largest effect were PCBs, a class of highly toxic chemicals widely used as industrial coolants before being banished in 1979. Interestingly, the main US maker of PCBs, Monsanto, apparently knew about and tried to cover up their health-ruining effects long before the ban went into place. Organochlorine pesticides, another once-ubiquitous, now largely banned chemical group, also showed a significant influence on diabetes rates.
