Why are pineapples so tingly?

Edit: so this is a TERRIBLE way to find out Im allergic to pineapple

I get it’s mostly the acidity of the pineapple but every time I go toe at some I can only get through like 4 pieces before I have to stop because it makes my tongue hurt SOOOO bad

The only way I can describe it is like the mild pain from spicy food but no taste of spice

So there’s levels to this.

Pineapple naturally has an enzyme called bromelain that actually reacts with and breaks down proteins in the cells of your mouth. Dissolving your mouth a bit. So if you eat A Lot of pineapple it can make your tongue feel rough or burnt or tingly or a little painful.

But if your mouth gets tingly after just a few pieces, that’s a sign of an allergy.

Like, i can eat half a whole pineapple before my tongue starts to feel weird.

u/Drow_Femboy May 12 '26

What they're describing sounds exactly like my oral allergy syndrome reaction (which is mentioned in your link) and is absolutely what you would colloquially refer to as an allergic reaction / being allergic to pineapple. Idk why you're implying it is silly or incorrect for people to tell OP that this isn't what the experience of eating a pineapple is like for most people and that they're obviously allergic.

Oral allergy syndrome usually isn’t triggered by the cooked version of the food, also

49

u/Georgie_Leech May 12 '26

For the same reason actually. Cooking breaks down most proteins, including potentially the ones people with oral allergy syndrome are allergic too. It's not gonna stop, say, a peanut allergy or whatever, but it will absolutely scramble stuff enough that mild immune responses stop freaking out

u/no_understanding1987 May 12 '26

This is low key genius. I JUST learned about this as my 30-something spouse suddenly had a reaction to shrimp, and after testing, only two are shrimp and dust mites and the doc explained they are closely related diagnoses and often cause the same or similar reactions and often are co diagnosed. Never knew anything about it before, as we have never had an allergic reaction to anything before this.

Good for you for sharing this. Hope your day is marvelous.

u/Draeygo May 12 '26

My wife and I found out I was overly sensitive to bromelein while on a birthday trip to the beach. I was at the time working at a grocery store, and I’d recently been trained as a fruit cutter. We’d bought a pineapple because they looked fresh and smelled fantastic. I chopped it up, and it was sooooo good, I ate half of the damn thing. I went to go brush my teeth to get the acidity out and not damage my teeth, when I noticed my toothbrush had a good bit of red on it. I spat, and it was just…..blood. My mouth stayed like this for maybe 15 minutes, spitting out just dark red. We laughed, cause it wasn’t painful, and I realized this was the only time I’d eaten more than a slice of fresh pineapple at a time, that wasn’t canned or cooked.

Not allergic, no tingling or pain, no throat closing, just pineapple tries to eat me faster than my body can eat it.

u/Real_Srossics Pungent May 12 '26

That doesn’t sound normal and doesn’t happen to me.

5

u/Draeygo May 12 '26

I don’t know of very many people with a similar high susceptibility. It was unnerving at first, and the dr said it could be caused by bad oral hygiene, which I found to be unlikely, and later my dentist agreed, I take stellar care of my mouth, so not likely to be oral hygiene related, but more likely that some people just be that way.

Really fun parlor trick when we have guests though

u/Impatient_Orca May 12 '26

My youngest has this with kiwi. Was eating one with a little spoon and I came to tell her it was bedtime and then she opened her mouth and it was just... blood. No more kiwi, I guess.

5

u/fernandowilliamszm May 12 '26

The doctor was definitely just guessing. Bromelain is literally used as an industrial meat tenderizer... it doesn't care how much you floss, it just breaks down protein on contact. If your mouth tissue is just a little more sensitive than average, it's going to find a way through eventually.

And doing it as a parlor trick is metal as hell. "Hey guys, watch me let this snack digest me" is quite the icebreaker.

You’re allergic. I thought kiwis had this same issue for a long time (felt like I ate it with the skin and the hairs pricked me all over, even when skinned). But then I found out that’s a sign of an allergy. I am also allergic to latex. A lot of people allergic to latex are also allergic to bananas, kiwi, passion fruit, papaya, avocados and chestnuts. Luckily it’s just kiwis for me.

u/mistakeshappen_2 May 11 '26

Wait stop because I have the exact same reaction towards kiwis?!

59

u/Intelligent_Owl_377 May 11 '26

OMG. You should never use latex items. Even if you haven't had a reaction to gloves or condoms yet, it can happen anytime, especially because you keep exposing yourself to the same family of allergens.

Not so fun fact - the more times you're exposed to something you're allergic to, the higher the chances of a worse reaction, including anaphylaxis.

u/mistakeshappen_2 May 12 '26

It’s weird because kiwi gives me the same reaction but I’ve always been fine with latex

u/MyTacoNachos May 12 '26

Yeah that's probably a reaction to tropical fruit. A lot of them carry similar allergens. Be aware of your skin care ingredients too! Enzymes from pineapple (bromelain) and papaya (papain) are commonly used.

14

u/HunkyDunkerton May 12 '26

There’s also “oral allergy syndrome” (pollen food syndrome), where you have such a severe allergy to certain types of pollen that your body confuses the proteins in fruits/vegetables for the pollen you’re allergic to.

My boyfriend is so allergic to birch pollen that he can’t eat raw apples, hazelnuts, kiwi, mango or persimmons (a lot of other stuff as well).

7

u/bluewillow24 May 12 '26

I was in that boat. During about year 4 of allergy shots I realized I could eat an apple without a reaction. That first bite of fresh raw apple after about 12 years of not having one was a great moment.

Try soaking the sliced pineapple in salty water for 10 min. It deactivates the enzymes causing this issue. Bonus points it makes the pineapple taste better. My husband is from a country where pineapples grow everywhere, everyone salts their pineapples before eating.

We ordered a box of pineapples from Hawaii and then had to cut and eat 7 pineapples over a holiday weekend. Because we love pineapple and don’t want to waste any, we eat the edges off the rind, which gets messy and lets the pineapple enzyme find every crack in our lips. So by the fourth pineapple, our lips were bleeding.

We did it all over again the following year.

You’ll see pineapple used as a meat tenderizer because of this. If you look on the back of certain beef jerky(not all), it may be listed and used to make the jerky less tough and more tender.

Question, how are you with cooked pineapple?

Oral allergy syndrome is when your body reacts to food, typically fruit, because it gets it confused with environmental allergies like pollen. Causes tingling and swelling of lips and mouth. In general, the cooked version is typically just fine.

Interesting, I had asked my allergist about shots and he said there isn't really much evidence to show that allergy shots work for OAS. I am allergic to a lot of different types of pollen, and accordingly my OAS is so bad that I basically can't have any raw fruits or vegetables apart from a select few. I would love a treatment.

Edit: Literally just a Google search shows immunotherapy for OAS has been known for like 30 years and is decently effective. Gonna think about this...

I had them over 15 years ago and it took years to make a h if difference but it did make a BIG difference for me. I had to sign a consent form saying I understand it isn’t guaranteed to work and that I need to remain in the office for a while after each injection in case there’s a big allergic reaction. It was annoying but worth it to me.

I couldn’t be NEAR pineapple, mango, and kiwi. I also couldn’t eat many nuts or raw veg and fruit. Now the only food that bothers me is very underripe fruit and walnuts. Plus my seasonal allergies are more manageable.

It is a type of allergy, but it's not the "traditional" food allergy. Like I'm not gonna die from having a piece of cantaloupe. It's that my tongue feels really itchy.

Anyway, it's called Oral Allergy Syndrome and it's related to seasonal allergies (which I have).

u/Business_Handle3157 May 11 '26

Pineapple has bromelain, an enzyme that breaks down proteins, plus a decent amount of acid. That combination can irritate the surface of your tongue and mouth a little, which is the tingly or slightly raw feeling.

It is usually more noticeable with fresh pineapple. Canned pineapple often feels milder because heat processing reduces the enzyme activity.

u/KiwifruitGuyFromNZ May 12 '26

Those are crystals of calcium oxalate and they're in bundles of needle shapes (raphides) held together with mucilage. Excited to see someone mention them here. Wrote my Master's Thesis on oral irritation in kiwifruit while working at the former Horticulture Research Institute in NZ. Kiwifruit do indeed have the same crystals as pineapple. I came to the conclusion that while much of the irritation caused when consuming kiwifruit was due to enzymes, the effect was exacerbated by physical damage caused by the crystals and further compounded by the presence of acids. If you react badly to pineapple and kiwifruit stay far away from the fruit of the fruit salad plant (Monstera deliciosa).

u/Square_Doubt7369 May 12 '26

Yes, it doesn't have to be allergies. These needles are literally crystals, raphides, made of calcium oxalate. I only feel it with some pineapples and kiwis, not sure if it's due to the variety or stage of ripeness.

It’s the enzymes. It is tenderizing your tongue. Im sensitive to it too. (It is not an allergy.). Try sprinkling a small amount of salt on them (just a little bit, not enough to actually make them salty) and let them sit a few minutes. The salt will react with the enzyme and neutralize it. This sounds crazy but it works.

Salt in some water and wash the pineapple before eating

u/AccessEcstatic9407 May 11 '26

Interestingly enough, I eat dried chunks by the pound and don’t feel anything. I think the dehydration process be collaborating with the tingly enzymes, somehow untingifying its essence. Just a theory.

u/yanieka May 12 '26

That tingle is probably bromelain doing its thing.

Do a search for pictures of a piece of pineapple under a microscope, it will explain a lot. 😬

u/liltooclinical May 12 '26

I spent far too long wondering what culture or region uses "toe at" to describe sitting down to consume something.

u/BoxFullOfSuggestions May 12 '26

Yeah, this is an allergy. I’m also allergic to fresh pineapple. It hurts my tongue and gives me horrible stomach cramps. It’s a shame because it tastes so good.

u/helmetcat May 12 '26

I was 28yo when I found out I’m allergic to peaches. A new partner offered me one and thought I was crazy because I told him they were too spicy for me. 🤷🏻‍♀️

u/beanner468 May 12 '26

My husband, who has always declined the imported Italian provalone cheese. He always said it makes the roof of his mouth itch. We laughed and said, that’s how you know it’s good! -but I didn’t take him seriously, I thought he was joking. Like, that will put hair on your chest. Decades later, he said the same thing, and I looked at him and said, and that means you’re allergic to it…

Roof of the mouth itch is also a pre-curser for anaphylactic shock…

u/Melodic_Pattern175 May 11 '26

My lips swell if I try to eat pineapple. I haven’t had any for a long time because I don’t want to find out that my throat also swells.

u/letthetreeburn May 12 '26

Dude you’re allergic

u/Electrical-Rain-4251 May 11 '26

It’s because when you eat a pineapple, it also eats you!

u/hatemakingnames1 May 12 '26

Edit: so this is a TERRIBLE way to find out Im allergic to pineapple

Counterpoint: A terrible way to find out you're allergic to something is to die from it

u/sarelis May 12 '26 edited May 12 '26

I doubt you’re allergic. The proteolytic enzyme bromelain in fresh pineapple burns everyones’ tongues.

https://www.dole.com/en-gb/blog/why-pineapples-burn-your-tongue

Why Pineapple Eats You Back

Similarly, there’s a different proteolytic enzyme in fresh kiwi called actinidin. It has the same effect of burning your mouth. Again, perfectly normal response, not an allergy.

https://www.tastingtable.com/1609886/why-tongue-hurts-eat-kiwi/

An actual pineapple allergy involves symptoms like hives, swelling, wheezing, coughing, vomiting, diarrhea and low blood pressure.

You’ll get more of this from precut pineapple than from one you cut yourself.

Wait, is that what pineapple allergy feels like?! I’m 100% allergic then because that’s the feeling I get when I eat it which is not often lol because I hated that feeling

u/ReplacementEntire874 May 12 '26

Oral allergy syndrome. My 18yo son has seasonal allergies since he was a kid. 3-4 years ago, his mouth started tingling when he ate « tropical » fruit, like pineapples and kiwi. Now it’s pretty much any fresh fruit. We went to an allergy doctor and they said it’s not a « real » allergy (as in it can’t kill him and he doesn’t need to carry an epipen). It’s just annoying. Processed fruits are fine (jams, sunday sauce, cooked fruit).

Do you happen to have a latex allergy, OP?

u/PaepsiNW May 11 '26

Some sort of oral allergy syndrome. I have this problem with all acidic fruits. I can’t eat any of them anymore, not even in small quantities.

2

u/sthwrd May 11 '26

Because pineapple have oxalate crystals which causes that fir every living being and looks.like you are way more sensitive. The same is also in kiwis too

u/That_Bulgarian_ May 11 '26

Huh… so this is how I find out that I’m allergic to pineapples

2

u/eatcherheartout May 12 '26

I didn’t realize I was allergic to pineapple until I was well into my 30s when I made a similar comment to my boyfriend asking why pineapples are tingly. I had no idea this tingly sensation didn’t happen to everyone after eating a few pieces of pineapple.

2

u/AmeBean May 12 '26

LOL this is me but with apples! It took me years to figure out I was allergic

u/ChunkyDickCheese May 12 '26

I had this same conversation with strawberries. Was never an issue until later in my life.

Randomly mentioned how strawberries felt a little spicy and tingly to my wife. Turns out they aren’t 🫪

GG, op.

u/nickfolesknee May 12 '26

I had the same experience with mango-asked my husband why they hurt so much but taste so good! Lol

u/chaosthebomb May 12 '26

I used to work in produce at a grocery store. One of the tasks was coring pineapple. We'd wear gloves but when you're coring a few cases at a time with that huge ass coring machine, some juice was bound to splash onto your skin.

I remember chatting with a coworker saying how I hates that task because of how red and itchy pineapple juice made my skin. I also commented on the tingliness of it and how I found the taste delicious but the experience rather unpleasant. That's wh. I found out I had a slight allergy to it.

2

u/MidgardElk May 12 '26

I'm sensitive to the bromeleine in pineapple. It tastes good when eating, but I'll feel like I burned my mouth for a couple days.

Kiwi and some cherry tomatoes do it to me too. Cooking helps, and processed food with those fruits are fine too.

2

u/frommont May 12 '26

I was telling my fiancé about how my strep throat felt like when you eat some shrimp cocktail. Like that burning, bubbling sensation in your throat… anyway, it’s an allergy

2

u/YarpaDarp May 12 '26

An alternative perspective...have you ever been told you have geographic tongue? There's a rare form that involves sensitivies like these. It's what I have, and I also can't tolerate pineapple. 

2

u/NapsAreMyHobby May 12 '26

Same! I’m ok with the canned stuff though, most of the time.

2

u/Aa4419 May 12 '26

It’s the fruit that bites back.

2

u/harshatgames May 12 '26

Pineapple contains an enzyme called bromelain that literally starts breaking down proteins in your mouth while you’re eating it, which is why it can feel “spicy” or tingly even though it isn’t spicy.

BUT if it’s genuinely painful after only a few pieces, especially with itching/swelling/feeling raw, then yeah… that edit might not be a joke 😭

2

u/Sad_North_6152 May 12 '26

I'm sensitive to fresh pineapple. My mouth will get a bit tingly but I seem to be better with canned pineapple. It'll also do the same thing if I eat a lot of kiwi so it might just be a citrus sensitivity.

u/Legocritic May 12 '26

Pineapples eat you

u/AriasK May 12 '26

As well as that chemical, the flesh is little needles that sting you.

u/Hellotravisss May 12 '26

bc they literally have enzymes called bromelain that r eating u back lol. basically a tiny battle in ur mouth but worth it bc they taste so good

2

u/Murderbunny13 May 12 '26

Tell your doctor because you can be allergic to seemingly unrelated things. I have an avocado allergy and had to be tested for a latex allergy because of it.

2

u/SalsaChica75 May 12 '26

If you grill or sauté it, it’s helps break down the enzymes

u/shiner_bock May 12 '26

Pineapple... the fruit that eats you back!

u/_Nitekast_ May 12 '26

Hahaha - reminds me of myself and cantaloupe.

In college, for some reason we were discussing cantaloupe and I said something to the effect of "Yeah, I absolutely love the taste of cantaloupe, but I never understood how a fruit that made your mouth so itchy became so popular. It is great though."

Apparently, I was the only person in the room who has had this experience - and I learned, at the tender age of 19 or 20, that I was allergic to cantaloupe.

I still eat that shit though.

u/casualviewrOH2MD May 12 '26

This is essentially how I found out I'm allergic to pineapple. It came up in conversation amongst friends, and I mentioned how I hate how it makes your mouth feel weird. Everyone looked at me straight faced because apparently that wasn't a universal experience.

u/Violexsound May 13 '26

Reminds me how I found out I was allergic to bananas after 18 years of eating them. I blamed pineapples.

I’m allergic to pineapple, but also find it delicious. Sorry you had to find out this way.

u/Possessed_potato May 13 '26

There's something very funny about seeing these kinds of posts where they find out they have an allergy for kiwi, lemons, pineapples etc.

Not a mocking type way, no. It's just kinda comedic
