Allergies: what are they FOR?





I have wondered what on earth allergies are for: can there be some underlying benefit?

This essay in Mosaic Science proposes a new theory (it's your bodies way of getting rid of toxic or noxious substances) in comparison to the prevailing theory (it originates in the way your body fights off infectious parasites such as ticks and worms).

I'm not sure I totally agree with the new theory, though I think it raises some good ideas.  Frankly, I was never wholly convinced by the prevailing theory anyway...
