Oral Food Allergy Syndrome List

Updated on May 24, 2019

Oral Allergy Syndrome Food List

At times, the human body can seem mysterious and many questions are often left unanswered. Today, we will be discussing Oral Food allergies. These allergies are often associated with fruits and vegetables which may have an underlying cause.

When I was a child I had eaten a fruit cup, moments later I had noticed that my eye had become extremely itchy. Eventually it seemed to have gone away, a week later I had eaten a peach and was affected the same way. This time my eye had swollen up the size of a baseball. I was not only affected by peaches, but strawberries, uncooked apples, bananas, watermelon, cantaloupe, carrots and celery. The only difference was that my mouth would become itchy. My family thought I had been trying to get out of eating fruits and vegetables as many children do. The thing was is that I was serious.

Fourteen years later, I found out that I wasn’t insane. But, that these symptoms are known as Oral Allergy Syndrome. What lead me to this search was when I was feeding my daughter. She had just finished a jar of pears, all of a sudden the same jar came back up for a visit. As it turns out children have a 30% chance of getting the same allergies as their parents. This is unfortunate for her because the list is quite broad.


Food List, Causes, & Symptoms

The question was: “why these fruits and two vegetables”? What could be the underlying cause? As I stated previously, the list of my allergies is quite broad which go far beyond fruit allergies. I would often play outside as a child and came in contact with grass often. This contact would cause me to break out into hives. Since then my grass allergies had ceased, yet, it dictates the foods I eat.

Those with grass allergies may be allergic to the following fruits and vegetables:

· Peaches, Tomatoes, Oranges, Melons, and Celery

What does grass have to do with eating fruit and vegetables you ask? It all has to do with biology, more specifically protein. The proteins that are in these foods are common to those found in grass. Your body is mistaking these foods as a threat (in this case grass) and is letting you know not to eat them. It is quite annoying for anyone that does enjoy fruits and vegetables. I would often suffer the consequences to enjoy the taste of a strawberry. But, the more you are subjected to these foods the worse your reactions become. As you can guess I no longer enjoy the taste of a strawberry for the reaction has grown stronger.

Unfortunately, the list grows longer. If you have problems being outdoors and you are allergic to the following foods:

· Cantaloupe, watermelon, and honeydew

The culprit may be ragweed for the same reason as grass (similar proteins). If you are allergic to:

· Pears, Apples, Peaches, Carrots, Celery, Cherries, Kiwi’s, Plums, Parsley, Hazelnuts, and Almonds.

You may also be allergic to Birch Pollen. Lastly, those with mugwort allergies may also be allergic to:

· Apples, Kiwis, Carrots, and Celery.

Symptoms of Oral Allergy Syndrome are:

  • Itchy watery eyes
  • Itching of the mouth and lips (may be a burning or tingling
  • Swelling of the lips, tongue and throat
  • Vomiting

These symptoms usually are mild to severe and may only last a few seconds to a few minutes. The most serious symptom is anaphylaxis shock which can be life threatening. Remember, you only need to have one symptom for it to be a sign that your allergic.


If I told you that I am going to go get myself a glass of apple juice and eat some apple pie what would you say? You may think I’m nuts but the irony is I can drink most juices without any repercussions. The same thing goes for the apple pie as it does the juice. Now it may seem like all of this is complicated, and it really is if you don’t understand why. But, the reason I can eat and drink these foods is heat. When these fruits and vegetables are heated the protein structure changes enough to the point where my body doesn’t recognize it as the enemy. One treatment you can try is putting these foods in the microwave for several seconds. If you are highly allergic you may want to have an Epipen before you try (Yet, if you’re highly allergic to a certain fruit or vegetable I wouldn't risk trying it).

Today, we have looked at Oral Food Allergy Syndrome and the types of food that is most commonly associated with it (fruits and vegetables). The reasons these allergies exist, the symptoms of these allergies and a possible alternative to eating these foods. I hope this gives people who suffer from food allergies as well as those who associate with them a better understanding of what causes their allergies.

UPDATE; Oral Food Allergy Syndrome

Several weeks ago I was able to be seen by an allergy specialist, I explained my symptoms in which I was told I have Oral Allergy Syndrome (go figure right?). But, the usefulness came into play when they tested what I was allergic to. As I had stated earlier the list is quite large, but, more importantly I was able to confirm the fact that I am indeed allergic to Birch Pollen as well as Ragweed.

They find this out by pricking your skin with a vast amount of substances. If your skin reacts, then you are indeed allergic. Obviously, the more of a reaction the more you are allergic to that particular substance. In my case I felt as if a large quanity of mosquitoes had made a meal of me.

Special Note: The doctor was also able to confirm the fact that you are able to eat cooked produce.

Allergy Testing

It turns out I am allergic to 20 of the 41 substances tested. Luckily for me, most of these materials are avoidable and don't effect my everyday life.

      I really wish I would've been able to find an article like this 6 years ago when I first started experiencing this. Out of nowhere I developed seasonal allergies the first spring that I was away at college. At the same time, I noticed weird reactions to apples (a favorite fruit since I was little). When I ate them my lips, gums, and tongue would tingle or burn. Everyone in my family thought I was crazy, but I really felt like the two things were related because as my allergy symptons got worse, so did the reaction to apples - from the funny sensations to swelling of the tongue and lips and my eyes would become itchy and watery. The next spring I was taking a Food Science course because I thought it would be an interesting way to fulfill Science credits, and sure enough, I was assigned an article about OAS!

      After almost 2 more years of battling with my family doctor to get a referral to an allergist for my seasonal allergies, she finally saw me in the right mix of weather to see my symptoms at their worst and gave the referral. The testing showed extremely severe allergies to trees (one of the worse being Birch) and ragweed, and also allergies to grass, dust, and mold. I've been getting injections for almost two years now, and although I don't experience the terrible seasonal symptoms, I still can't eat apples, peaches, pears or almonds!

      This is a great article. It explains Oral Food Allergy Syndrome very well, one thing you may want to add to the list is that if your allergic to Bananas you may be allergic to Latex.

      Yes, so if you feel like your allergic to the world, it's because you probably are. Another relationship that I didn't include is between Latex and Bananas.

      Wow that was such a great article. I never knew that being allergic to fruits and vegetables could also mean I was allergic to certain types of weeds/grass!
