This is the continuing series of questions for you in the comments, here’s how it works. I’ll ask you a question, and you either answer in the comments or on your own blog and drop a link to the post.
Question:
What’s the strangest thing you (or somebody you know) is allergic to?
These days people seem to be allergic to all kinds of things. What’s the strangest one?
Here’s my answer:
My brother’s fiancée is allergic to lemons. Lemons? That seems really crazy to me. Why that seems stranger than being allergic to nuts, I don’t know. Maybe it’s just because it’s rarer.
So what’s the strangest thing you (or somebody you know) is allergic to?

I’m allergic to nickel, but I suspect that’s probably quite common…
I’m allergic to an additive that used to be put in flavoured milk.
Though it’s actually been illegal to use it since the mid-80s so I don’t have to worry about it any more.
I don’t know if allergic is the right word, but several things can make me sneeze: strong sunlight, mints, red wine and beer.
I think I’m allergic to alcohol, every time i have it i have this funny feeling, and sometimes i cant remember whats gone on, the next day the symptoms get worse, i can even be reduced to being unable to get out of bed…
In all seriousness, i dont think i am allergic to anything, i dont like eating fish so sometimes i pretend i am allergic to that 😉
I’m allergic to evergreen trees. Fortunately it’s only a contact allergy, and only produces an itchy rash… but it still means I have to be fairly careful at Christmas…
my mum is allergic to the bark of silver birch trees (amongst a myriad of other things)….we only realised upon moving to our house, which is surrounded by silver birches. 😛
I am allergic to the smallpox vaccine which is OK at the moment but you never know!
I really don’t like tomoatos. Although I really like tomoato sauces. Does “not like” count as allergic?
It could be convenient to be allergic to things you don’t like, but real allergies can be a serious problem, so pretending is probably not such a good idea.
As far as food is concerned, it seems to be acceptable not to like something because of the texture; liver seems to be the commonest example where people like the flavour and can eat pâté but can’t stand the graininess of cooked liver. I have tried to claim that I have a texture problem with broccoli, but somehow it doesn’t seem to work.
Allergic to broccoli… who is going to believe that?
I sneeze when I have mints too! I thought I was the only one.
As we’re on a bit of a DIY tip at the moment, I was telling Mr C that last time I did wallpapering, I found I was allergic to the paste. Thinking about it now, I believe it was whatever you use to put tiles up. I was helping my parents tile the bathroom, my hands swelled right up and I wasn’t allowed to do it anymore.
Boo.
I’m only allergic to one thing (that i know of), which is guinea pig hair. I’ve no idea why it’s the only animal fur i have an allergy against, but it irritates my skin and eyes. Stranger still it just developed one day out of the blue lol
dont know but ive had a runny nose for 28 years and am beginning to think im allergic to oxygen!
