However, when I was a kid, any gathering of children was likely to include a peanut butter sandwich. And no one suffered. No one died. No one even talked about allergies. Then, seemingly out-of-the-blue, nut allergies became a big deal and every classroom in America now contains at least one sufferer.
What's up with that?
Well, no one you knew died, but a few kids did die. In some cases, way back in the day, no one may have connected the death with the food.
Anyway, there’s evidence suggesting that the rise in allergies is in some way connected to the decrease in...parasites. Modern medicine finally reaches some isolated little village or South Sea island. The HCPs note, among other information, that the populace has a high rate of tapeworms and other disgusting things, and at the same time, note no allergies. No sensitivity to shellfish; no hay fever. A few years and a lot of pills later, parasites are a thing of the past, but the allergy rates are creeping up.
