What Is a Tree Nut Allergy?
A tree nut allergy occurs when the immune system reacts to proteins in certain nuts as if they were harmful. Common tree nuts include almonds, cashews, hazelnuts, walnuts, pecans, and Brazil nuts. Exposure can trigger reactions ranging from mild hives to severe anaphylaxis.
Is Coconut a Tree Nut? The Scientific Answer
Botanically, coconut is a fruit (a drupe), not a true nut. However, it may appear on allergen warnings because of its name and occasional coconut cross-reactivity. While many people with tree nut allergies tolerate coconut, an allergist should confirm safety.
How Common Are These Allergies in Australia?
According to ASCIA, tree nut allergies are among the most common in Australian children and often persist into adulthood. Coconut allergy is rare but documented. Anyone with suspected reactions should seek medical advice.
