Maybe this belongs in an allergy group, but since asthma and allergies
are so intertwined I would like to post here.

My understand is that allergies develop over a short period of time,
maybe two years, to something that you are exposed to too much, so the
body starts fighting it.
With corn, soy, wheat, nut, dairy products and derivatives in almost
everything in the typical American diet, it's no wonder that food
allergies and sensitivities are so prevalent. Add to that the fact
that crop diversity is just in the history books, and the air we
breathe is polluted, it seems amazing that so many people DON'T have
allergies and asthma.
If moving to a different area and being exposed to different pollens,
molds, foods, air gives one a fresh slate (until they develop
allergies to things in this locale), do you think that humans have by
and large been nomadic, and are we meant to be?

Has moving to a new place helped your allergies/asthma?

Discuss.
