Allergies are becoming more frequent in the western world. One in three people in Australia will develop allergies at some time in their life. One in 20 will develop a food allergy and one in 100 will have a life-threatening allergic reaction known as anaphylaxis.
Hospital admissions for anaphylaxis doubled in the ten years from 1994 to 2004, and were five times higher in children under five years old over the same period. This suggests the development of allergy in early life is increasing at a faster rate than in adults.
Children are more likely to develop allergies to eggs, dairy products or peanuts, while adults are more likely to develop an allergy to seafood.

Anaphylaxis isn't the sort of thing that goes un-diagnosed. If you have an anaphylactic reaction, you can't not know. So if the hospitals are seeing more it's because there are more to see.

You'd think so, but medical data is tricky. The definition also may have changed to become more lenient. Perhaps a new test was developed and now a lot of moderate anaphylaxis (that used to be something else) is now meeting the criteria. That would not surprise me either.

It's a well defined condition and it has no mild form. Your blood pressure either drops dangerously low or it doesn't.

What about the long term repetition factor?
I'm familiar with this WRT boating / sailboating and fiberglass hull repairs, you can practically swim in unpolymerized resin and catalyst its not overly toxic (its not food, but its not as toxic as some paints for example) and snort the fumes and it just doesn't matter... then at some unknown individual amount of exposure its massive allergic reaction time up to and including going into shock. Some boater people actually recommend working in pairs or hanging out with people when working with fiberglass because when you're number is up, you might need someone to call the ambulance. I think they might be overdoing it a bit, but whatever.
And after the reaction sets in, you'll never, ever, be exposed to uncured resin without the allergic response being as bad or worse.
So far I've not hit my limit... but I've heard of it happening to people the first time they patch a hull. Doesn't take much either, even a small project replacing a fitting can set off the allergic reaction until the stuff cures. Allergic people are fine after it cures and the boat airs out a bit.
There is some BS about allergen free or reduced allergen fiberglass, and some BS about it being less trustworthy in storm conditions and needs replacing more often and looks weird, and plenty of BS about respirators and gloves, its all very rumor based. Commercial hull makers seem to work around it by hiring illegal aliens so they don't have to care about health care and using megatons of ventilation and doing the glove/respirator thing. I'd suggest copying them at least 2 outta 3 preferably the ventilation and respirator options.
Anyway I don't think it far fetched that if soy is in all junk food and you eat junk food (aka soy) every freaking meal for 30 years, just like fiberglass resin maybe you reach some mysterious limit and start getting a sensitization reaction and you ignore it and next thing you're like 40 and outta the blue you're in shock from soy, or peanuts, or crustaceans or WTF. I know resin and epoxy and a couple drying oils all have that allergen response pattern.

That is a reasonable hypothesis. Of course, that would be a genuine rise in incidence rather than an artifact of reporting.
