Recently, it was noticed that Swiss farm kids have a lower incidence of asthma and allergies than the general population, so someone who read that study got a bug up their butt to replicate it in the U.S. with the Amish. Surprise, surprise--Amish kids are even less likely to have allergies or asthma than Swiss farm kids.
Farm kids in general are healthier: they're outdoors more than non-farm kids (chores and stuff), exposed to more potential allergens (animal dander, feathers, straw and dust, etc.), drink raw milk (with more allergens), and likely eat local honey (with local pollens). Their immune systems are exposed to a lot more, and is better able to recognize what is and isn't harmful, so doesn't go batshit trying to combat everything. And Amish kids do a lot more chores than other kids, and are more likely to drink raw milk and eat honey from their parents' beehives than other kids.
They noticed that a long time ago. This study is just throwing more money after the first proven study, and at a time when we can't afford it.
