7 Food Allergies You Didn’t Know Existed

We all know someone allergic to peanuts. I know at least two peanut-fearing beings, and I really do feel for them. Peanut butter is one of the best things I’ve ever encountered. Then there are those who are allergic to shellfish. I’ve never been a fish fan, and as a child I’m sure I pretended to be allergic to the slimy scales – anything that lives in the sea should stay in the sea, in my opinion. 

However, there are allergies that are slightly less common, and a bit more unusual. Here, discover the seven strangest food allergies there are.

Sesame seeds

You might not be that devastated if you find out you have a sesame seed allergy, but apparently it can happen. It’s more common in the Middle East, where sesame seeds are almost as popular as houmous. Almost.

Dried fruit

If you’re not a fruit fan, this may not bother you – but a dried fruit allergy is also possible. However, it’s more likely to be caused by preservative sulfites than the fruit itself. 


I don’t know about you, but I’m pretty sure I don’t have a marshmallow allergy – just last night I sat down with a plate of smores. It’s actually the gelatin and sugar that can cause an adverse reaction, and I’m not talking about a food coma.


I know what you’re thinking – an avocado allergy would be problematic, to say the least. I’m sure there are a number of “avocado cafes” in London now, where hipsters meet for Sunday brunch, retro cassette player and miniature canine in hand. Surprisingly, the proteins found in avocados are similar to those in latex – so if you’re sensitive to latex, beware the avocado.



Like the avocado allergy, the proteins in avocado are linked to latex. If you’re allergic to mangos, you might want to avoid poison ivy and poison oak – these plants contain a chemical called urushiol, and it’s best you don’t come into contact with it if mangos aren’t your friends.

Hot dogs

As you probably know, hot dogs aren’t the most natural food on the menu. Highly processed, the meat contains an array of additives and an allergic reaction could be the result of any ingredient found in them. Spoiler alert: it’s often the nitrates and yellow dye that are to blame.



I can only apologise for being the bearer of bad news, but some people are actually allergic to wine. Before you pour yourself a glass (I know this is a lot to take in), note that the hangover you had last week may well have been an allergic reaction. A wine allergy can also be mistaken for a cold or seasonal allergies, so be aware of any respiratory discomfort you experience the next time you open a bottle – especially if you have asthma. Side note: ladies, you’re twice as likely to have a wine allergy than men. Sorry.
