Can carrots cause allergies?

Can carrots cause allergies?

A person can be allergic to almost any food. While carrots are nutritious and packed with beta carotene, these root vegetables can also cause dangerous allergic reactions.

An allergic reaction to carrots can be one element of oral allergy syndrome, which is also known as pollen-food allergy syndrome. A person with this syndrome is allergic to pollens in certain raw fruits, vegetables, and nuts. After eating a trigger food, they experience an itchy throat, mouth, or ears, reported.

If a person has a severe allergy to carrots, their reaction may be serious, especially if they have come into contact with the raw vegetable.

Anyone with a food allergy should consult a doctor to determine the best course of action.

In this article, we examine the signs, symptoms, and diagnosis of a carrot allergy. We also look at the types of foods to avoid.




  • A person with a carrot allergy is more affected by consuming raw carrot
  • An allergic reaction to carrots can lead to itchiness in the mouth and throat.
  • A person with this allergy may notice symptoms after eating raw carrot. Cooked carrots tend to cause more minor reactions, as the cooking process breaks down allergens.

Symptoms of a carrot allergy can range from mild to severe, but they are likely to be mild.


Typical symptoms include:


  • An itchy tongue, mouth, lips, ears, or throat
  • Swelling in the mouth area
  • A scratchy feeling in the throat

Occasionally, symptoms may be severe and require treatment. More severe symptoms can include:


  • hives
  • breathing problems
  • swollen skin
  • a cough
  • a sore throat
  • sneezing
  • a runny nose
  • tightness in the chest
  • congestion

In rare cases, anaphylaxis can occur. This life-threatening allergic reaction causes the body to go into shock and requires emergency medical attention.

When introducing a baby to any new food, it is important to watch for allergic reactions. If any symptoms develop, consult a doctor.


How common is a carrot allergy?


Carrot allergies are not among the most common in the United States. However, they are fairly common in Europe.




Anyone who suspects that they have an allergy should visit a doctor.

The doctor will likely begin by reviewing the person's symptoms and family history. They may then recommend allergy testing.

A skin prick test, also called a scratch test, may be used. It involves the doctor placing a tiny amount of the allergen, in this case carrot, on a person's forearm or back. They then prick or scratch the area, allowing the allergen to penetrate the skin.

If the test is positive, a person will develop small red bumps at the site.

The doctor may suggest that a person follow a special diet for several days and keep a food diary to record what they ate and how they felt. This information will help the doctor to determine whether the person has a food allergy.

Depending on the results, a doctor may then suggest a food challenge, in which a person eats a small amount of a suspected trigger food and any reactions are recorded.
