The United States has one of the highest diabetes rates in the developed world—and the malady is spreading faster here than it is in most other rich nations, a recent Lancetstudy (registration required) found.
I've always associated our diabetes problem with the steady rise in sweetener consumptionsince the early '80s, triggered by the gusher of cheap high-fructose corn syrup that opened up at that time. But another culprit may be contributing, too: exposure to certain pesticides and other toxic chemicals. A new peer-reviewed study published in the journalDiabetes 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./.../
