Oranges make me go all dithery and flushed. Even thinking about them (like now) makes my mouth water.

Not sure if that’s fairly common or not.

Mind you, it nowhere near as weird as a post I just read where someone had reported their nose runs every time they smell tomato ketchup:)

My adult age DS has an oral allergy with many raw foods. For example: Cabbage, carrots, avacados, cantaloupe and some others. His mouth gets itchy ( his words). Once the food is cooked, it removes the enzyme and he is not bothered.

My body is intolerant of pork. Not the actual meat but the antibiotics, steroids and other drugs the animals are given. I have a severe reaction from commercial pork, bacon or sausage. It has varied in severity throughout my whole life. It is an uncommon sensitivity.

I used to love fresh pineapple. Then, about 2 years ago I purchased a fresh one....my tongue felt like it was stuck with pins and needles. It looked fine...but the pain! On a scale of 1-10...maybe a 5. It lasted ALL day. But...cooked pineapple...is fine.

Sensitivities are strange sometimes. My sister devolved an allergic reaction to meat! She has never bothered figuring it out by going to an allergist. She is allergic to fire ants and bees since young adulthood.

I love milk. Especially milk and cookies. At 67 years of age I became lactose intolerant. I miss whole milk, whole milk yogurt, and despise substitutes.

I sneeze when I eat peppermint candy.

Several years ago I became intolerant of red meat. Based on some online research, I believe it's a reaction to a tick bite and is called alpha-galactose syndrome, but there seems to be no diagnostic test for it. Fortunately for me, pork and fish are still on the menu, but I miss those steaks.

The last nanny that my grandchildren had was very allergic to pineapple.

It's the raw pineapple that's problematic, for sure. I love it, but have to restrain myself from eating too much because it does make my mouth sore.

No such problem with canned/cooked pineapple.

1 thing I am aware of is that as I've aged, my skin has thinned, and I'm guessing that holds true for the skin on my lips and inside my mouth as well, perhaps some of us have thinner, more delicate skin than others?

The pineapple sensitivity happens to me sometimes. It feels like the sides of my tongue are burning, although I think nicole did a better job of describing how it feels. For me, it doesn't last all day; maybe more like an hour or two.

sushipup's explanation is interesting. Since it only happens to me some times, I'm guessing that different pineapples must have varying levels of bromelain. Maybe that would depend on the type of pineapple, time of year harvested, the ripeness of the pineapple, perhaps where it was grown or the type of soil or a combination of those factors.

When I was a kid pineapple made my tongue feel like it was being cut up with razor blades. The same thing happened when I ate raw walnuts or pecans. Thank goodness that went away. Some people are very sensitive to mangoes, mostly the peel, stems and leaves, reaction is similar to poison ivy.

The same ingredient is why you can't use fresh pineapple in jello, or it will never set. You have to use canned. It's "tenderizing" the gelatin.

graywings....me too. Especially Altoids or Tic Tac's. And.....every time....DH laughs at me.

Our family was visiting the city and stopped in at a Chinese bakery for a treat. DS loves pineapple, and had a pastry with pineapple in it. Then we continued walking around on a sunny day. Next morning, we saw DS with a rapidly spreading rash! It didn’t itch, but it looked like it should. We put a call in to the doctor’s office, they wouldn’t open for a few hours. Meantime, DH starts googling. By the time we talked to the pediatrician, we learned that pineapple and sunshine can, indeed, cause such a rash. Pediatrician confirmed that.

A few years ago I started experiencing the pins and needles feeling on my tongue when eating fresh pineapple, apples, carrots and melons. Cooked or canned, no problem. I miss eating them fresh, especially melon. I've been noticing a slight itchy feeling in my mouth when I eat avocados, so it's time to stop before I get a worse reaction. Why can't I have this problem with chocolate, cookies, cake and ice cream!!!

I can't eat fresh pineapple because it bothers my mouth but I can eat canned pineapple which isn't nearly as tasty as fresh so I don't bother eating pineapple.

Me too! Every few years I will try a small piece and same sharp pin like feeling. Several times as a kid my tongue would actually bleed. Learned my lesson and like the others, canned mostly does not do this - except if it is unsweetened. Good thing is it is easy to avoid. Interesting note on mangoes - I don't like them but wonder if that is why. Our whole family is very allergic and I learned after skin testing on all the kids that the foods they hated turned out to have reactions on the skin tests. I attributed it to the body telling the brain - not to eat it! When the kids would not eat a particular food, I would not force it - made life easier with a house full - and I think prevented reactions. With an allergic family, you learn to read labels - very carefully. And learn the safest is to make everything from scratch.

Thanks for the suggestion. Will have to try it.
