What Is A Coconut Allergy?

A coconut allergy is an adverse immune response after consuming coconut or its products. Coconut allergy affects a small percentage of the population, estimated to be around 0.5-1%. However, its prevalence may be underestimated as it is often confused with tree nut allergies or misdiagnosed due to cross-reactivity with other allergens. 

Coconut is classified as a fruit, seed, and drupe. Yet, this allergy often cross-reacts with nut allergies. The most common cross-reactivity occurs with tree nuts such as almonds, hazelnuts, and walnuts. Some individuals with coconut allergy may also experience cross-reactivity with latex, a substance in certain rubber products. 

Coconut Allergy Symptoms

Symptoms of coconut allergy can range from mild to severe and may include the following:

  • hives
  • itching
  • nausea
  • skin rash
  • dizziness
  • coughing
  • diarrhea
  • sneezing
  • swelling in the throat
  • difficulty swallowing
  • runny nose or eyes
  • shortness of breath
  • fast or slow heartbeat
  • anaphylaxis — a life-threatening emergency involving difficulty breathing

Coconut Allergy Diagnosis

Diagnosing a coconut allergy can be done through a skin-prick test, blood test, or an oral food challenge. During a skin prick test, a small amount of coconut extract is placed on the skin, and a small prick is made through the extract. If a raised, red, itchy bump appears at the site, you are probably allergic to coconut. 

A blood test can measure the levels of IgE antibodies in the blood that are specific to coconut. If the levels are elevated, it may indicate an allergy to coconut. This test is considered accurate but may take a few days to produce results.

An oral food challenge is considered the most accurate method for diagnosing a coconut allergy. In this test, the individual is given a small amount of coconut to eat, and the reaction is monitored. If an allergic reaction occurs, it confirms a coconut allergy. While this test provides accuracy, it can be dangerous. That’s why it should only be done in a clinical setting. A medical professional should only make a diagnosis, as self-diagnosis may result in a severe reaction.

Coconut Allergy Treatment

If you have a coconut allergy, the best way to treat it is to avoid coconut products altogether. This includes not only the flesh of the coconut, but also coconut milk, oil, and other coconut-derived ingredients that are commonly found in food and personal care products.

If you have already been exposed to coconut and are experiencing an allergic reaction, you should seek medical attention immediately. In severe cases, a coconut allergy can cause anaphylaxis, a life-threatening reaction that requires immediate medical attention. It’s important to carry medications such as an antihistamine and an emergency epinephrine auto-injector with you at all times. You should also inform those close to you about your allergy, as well as restaurants and other food service providers, to ensure that they are aware of your needs and can take steps to accommodate you.

It’s also a good idea to familiarize yourself with food labeling regulations and become an expert at reading ingredient lists to avoid coconut products and stay safe. Book an appointment at NY Allergy & Sinus Centers for a personalized treatment plan for coconut allergy.
