A coconut allergy is a rare but serious reaction to coconut proteins. While some people experience true coconut allergies, many others have allergy-like symptoms due to cross-reactivity. This means their immune system mistakes a protein in coconut for a similar protein in another food, such as tree nuts (like walnuts). The similarity in protein structure triggers an allergic reaction even though they don't have a true coconut allergy.
Understanding Coconut Allergies and Cross-Reactivity
- True Coconut Allergy: This is a genuine immune response specifically to coconut proteins. It's relatively uncommon.
- Cross-Reactivity: This is more frequent. An allergy to one food (e.g., walnuts) can cause a reaction to coconut because of shared protein structures. Studies have shown a correlation between allergies to tree nuts and reactions to coconuts. Research indicates that two people allergic to walnuts reacted to coconuts due to a cross-reacting protein.
Symptoms of Coconut Allergy
Symptoms can range from mild to severe and include:
- Hives
- Rash
- Itching
- Swelling
- Nausea
- Vomiting
- Diarrhea
- Wheezing
- Difficulty breathing
- Anaphylaxis (a life-threatening emergency)
Diagnosis and Treatment
A doctor can diagnose a coconut allergy through skin tests, blood tests, and an oral food challenge. Treatment depends on the severity of the reaction. It might involve avoiding coconuts and coconut products and carrying an epinephrine auto-injector (like an EpiPen) in case of severe reactions. If you believe you are allergic to coconut, this should be reported to your GP, who can either arrange a test if he or she is qualified to do so or refer…
Avoiding Coconut and Coconut Products
Completely avoiding coconut and coconut products is crucial if you have a confirmed allergy. Be aware that coconut can be hidden in many processed foods, so carefully reading food labels is essential.
