Allergies: You have to build an immunity!

My fears of the Nanny State syndrome appear to be bourne out:

Stuff covers the fact that 'avoiding' allergens may not be the way to go. Perhaps you need to be exposed (carefully) and be allowed to build tolerance.

Wow. Is this revolutionary thinking?

Surely this is the only way to deal with some allergies.. especially for the stuff that's hard to avoid.. ??

Even a tolerance is better than anaphylaxis, rash and all...
