Define significant. Sesame allergies are pretty rare, but, where present, are extremely dangerous. Generally these mandated warnings are based on some combination of prevalence and severity; sesame allergy is rare but use of sesame is common and the allergy is lethal, so it gets a warning.
The one that confuses me is lupin. It’s one of the 14 mandated allergen/intolerance warnings in Europe, but is not at all commonly used.
It's commonly used as an alternate plant in soy fields, for crop cycling purposes. I forget which nutrient it prevents oversaturation of, but there is one.
Probably some combination of lack of exposure in early age, sterility hypothesis in the west and something in the way the food industry makes highly processed foods.
Identical twins have 70% chance to share same allergic diseases vs 40% for non identical twins, and both of which is vastly more common than their prevalence in the general population. Though this also demonstrates environmental factors play a significant role.
That said, the human immune system includes significant randomness so environment may be even less important than generally assumed.
How do you compare non identical twins to the general population? Aren’t twins, even non identical likely to share the same diet, the same environmental factors and maybe even the same viruses etc - all could be contributing factors?
We discovered our kid's sesame allergy when I fed some hummus on a pita at age 18 months resulting in a serious reaction that almost had me calling 911. It wasn't lack of early exposure.
It's entirely possible that the allergy will go away though. The immune system can shift and change over time in ways that cause it to not overreact to the allergen anymore.
And frankly some mix of self diagnosis/anxiety from parents. In my circle, there's a few obsessive mom-types that are so fearful of allergies/vaccines/etc but their kids have never actually been diagnosed by a doctor.

Lupine fixes nitrogen from air, making it effective as fertilizer.
Depends on the allergen and individual... What makes me feel sore or achy for a day or two might kill someone else.

More likely the underlying causes are genetic.

But why would it have apparently increased so much in the relatively recent past if the cause was genetics?
