Maybe. Unfortunately, it's probably not what you are hoping for...
Rotation diets are often associated with "woo" practitioners more than with conventional management-- so many allergists will have a knee-jerk negative reaction to them upon principle, just through that association with naturopathic "allergy" diets. As long as you're willing to be VERY clear that you're simply looking to avoid over-reliance that might lead to sensitization, and seeking recommendations on that basis, there's little harm in asking the question, anyway.
Unfortunately, the best way to avoid additional sensitization is probably just really aggressive management of what you KNOW you're allergic to, and avoidance of some things which have known interaction with the system there-- antacid/proton-pump inhibitor meds are among those implicated.
Skin sensitization is another known issue (or suspected, perhaps I should say). So yeah, take a look at the top sensitizers for adults and avoid topical application of those things, maybe? Given what you've stated about almond, in fact, I'd think that is a likely sensitization pathway for you personally, which may have more relevance than anything else in the picture.
Sesame (or other seeds, like sunflower), peanut-and-treenut are the leading culprits after fish and shellfish. At least in North America and in adults.
Of course, nobody really knows for sure what it means to a family that has a non-Western diet/lifestyle in particular, either. But over-use really doesn't seem to "trigger" allergies in adults. At least not by itself-- but my guess is that a garden variety allergist (even a good one) isn't likely to have a lot of insight into WHAT is going on with your adult onset allergies in particular-- or how to get you some insurance that you won't develop more of them. Unfortunately.
Nobody really knows why some people suddenly start to develop allergies, much less what makes them STOP doing so.
It might help you to understand which protein super-families are somewhat related to one another-- I'd ask about cross-reactivity rates in adult patients. It might be worth it to at least know what things, demographically speaking, you're more likely to develop problems with if you're going to-- if that makes sense.
For example, while I've never had a major reaction to molluscs, it's very likely based on my crustacean allergy. For some reason those are "grouped" together.
Peanut is clustered that way with a few things, too, as are particular treenuts.
This might seem obvious, but I don't see it mentioned here.
If you are taking any antihistamine, if possible stop. If the doctor wants to do any testing you have to have it out of your system for a certain amount of time. (Sorry, I don't remember how long. An week?)
That includes any other meds that have antihistamine in them...certain colds meds, and gravol (anti-nauseant, not sure of US name or if it's a different med there.)
Nothing much to add just in to wish good luck, hoping this is your 'prince' after the frog. For me I always feel like I don't have time to deal with my own personal allergies when there's so much I have to do. The paradox of a mother's self-care.
I agree with CM. I hope you find a great allergist. And I could be wrong but I think you can get RAST tested without going off meds. Our doc is not big on RAST and does skin usually but I think that's the case. Testing is not the be all and end all but it can be helpful. But it isn't necessary. If you walked into most allergists and described your past reactions they would give you a script for epis and emergency plan.
I can't remember your whole story but if you are having some mystery reactions testing via RAST could help you figure out the cause and so could in office challenges.
I would want the very best allergist I could get if I were you. Best wishes!
Some people just historically don't skin test very reliably, too-- if you're one of them, then it makes much more sense not to bother and just go with RAST and history.
Yes-- antihistamines have no impact on circulating levels of IgE.
We RAST (or if you want to call it IgE test) with the one kid on daily Zyrtec. For SPT he goes off Zyrtec but for oral challenges he actually stays on Zyrtec because it doesn't alter threshold all that much. Doc also reasons since he's on daily Zyrtec it is a more valid test than if he went off anti-histamine for a challenge.
The one thing I would look into given your allergen set is high heat treated milk. That has some validity to it that is somewhat of a treatment that also affects quality of life, and possibly positively influences contamination thresholds for untreated milk. Good, solid data on that one as long as you have an up to date doctor and adherence as an adult. I think there is some validity to dampening down your allergy cup through environmental allergy immunotherapy which is well established.
In essence you can't do much about the shellfish and almond but there are some adjunctive allergy issues that can be attacked with a great statistical likelihood of success that can translate into a better overall outcome.
