Can you develop a food allergy from food you've never had problems with?

I've eaten shrimp my entire life, but last night I ordered some at a mexican restaurant, and after I had eaten a few, my tonsils felt tighter, like maybe my throat was beginning to swell shut. I quit eating and a few hours later the feeling went away.

Could I have developed an allergy to shrimp 17 years into my life? Or maybe I was allergic to some spice they put in there? Or maybe I might just be getting sick from something completely different?

Yes, I suddenly developed an allergy to penicllin, which I had taken many times previously without any problems. This can apply to anything, including food. They say our system changes every seven years. If you particularly like eating shrimp though, an accupuncturist will be able to cure you of the allergy.

Yes you can develop an allergy later in life. My sister developed an allergy to nuts. I on the flip side, lost my allergy of dairy products. Things can really shift over one's lifetime.

it is possible that you are allergic to shrimp now. if you were fed shrimo before you were old enough it could come back with a vegence now.

Yes, you can develop allergies to anything at anytime. with seafood it is usually the iodine in the food, but not all seafood has iodine in it, just those that turn pink when you cook them

Yes, one can develop an allergy at anytime to anything, regardless of length of time they have been exposed to what is now causing you an allergy. Shrimp, most definitely, for it has a high iodine content, and many, many people develop allergy to shrimp, after having eaten it for many years.

About 2 years ago I suddenly developed and allergy to tomatoes....Never had a problem with them before.

Same thing happened to me, ate shrimp all my life and then one day I was rushed to the hospital.....) didn't think I was going to make it, my breathing was being restricted....(at age 20)

The doctors said for me to NEVER eat fresh shrimp.....so I tried frozen and that worked out for years....then last spring....again..this time I was told I would have to carry a EPI pen if I try any kind again.......I'm so done.

People often develop allergies to shell fish. And yes, you can begin allergies at any stage of life to food that never bothered you before.

Yes you can. Your body changes as you get older. ...It might be the seasoning but i would try shrimp once more with out any of the seasoning and see if you have a reaction if so then dont eat shrimp.

Seafood is very different when it comes to allergies. You can becoame allergic to it later on in your life even though you have never had an allergy to it before. This includes not only finfish( trout, salmon,ect...), but your shellfish as well(lobster, crab, crayfish, shrimp, ect...). This situation can be very dangerous. Luckily you noticed signs of an allergic reaction.

maybe see a docter

you can gain an allergy to anything over the years. i recently became allergic to dust.

You can develop allergies later in life I didn't start have allergies untill I turned 18, or it may be one of the spices they cooked with

I'm always becoming allergic to things that I haven't been allergic to before. I used to be ok w/shell fish then i was highly allergic for years now i can eat it again. Bodies are strange. It could also be something that they cooked it in or something that the pot cooked last ect.

yeah it can occur at any age just developed more myself
see a doctor and they can refer you to a specialist

Yes you can. Your body chemistry changes every 7 years. So things you haven't had problem in the past with you could all of a sudden have an allergy too. It sound like you were having a reaction tho I am allergist to shell fish and what happens to me is my throat swells up I break out into hives and have trouble breathing. So I would go to and allergist and get tested. Better safe than sorry. And if you are allergic to shell fish you also can use any product with iodine in it either for this is made from the shells of shell fish. Be careful.

the answer is yes, for 20 years I have been able to eat anything I want without a problems, now I have to be extremely careful of what I eat because it can cause me to go into anaphalctic shock. The cause is unknown and rare but pointing to a blood transfusion I had after childbirth. But now, I cannot eat anything red, cheeses, chocolates etc. the only way to know is by trying to eat a small portion of shrimp again and if the symptoms come back then I can guarantee it is an allergic reaction.
