What Are Tree Nuts?
Tree nuts are hard-shelled fruits that grow on trees and include almonds, walnuts, pecans, cashews, hazelnuts, macadamias, and pistachios. While peanuts are also a common allergen, they are legumes rather than tree nuts. This distinction is vital when identifying allergic reactions.
Tree Nut Allergies Explained
Tree nut allergies occur when the immune system mistakenly identifies proteins in nuts as harmful, triggering an IgE-mediated response. Symptoms may include:
- Hives or itching
- Swelling
- Stomach upset
- Severe cases of anaphylaxis
Tree Nut Allergy Statistics in Australia
According to Allergy & Anaphylaxis Australia, tree nut allergies are among the leading food allergens. Research suggests up to 2% of Australians may have a tree nut allergy, with many carrying it into adulthood. This affects schools, workplaces, and hospitality settings where shared food is common.
Is Coconut a Tree Nut?
Botanical Classification of Coconut
Coconut is not a nut but a drupe—a fruit with a hard stony covering around its seed. Despite its name, it is unrelated to tree nuts such as cashews or almonds.
Why Coconut Is Labelled a Tree Nut in Some Countries
In the US, the FDA requires coconut to be labelled as a tree nut. This rule is based on legal precaution rather than botanical fact, leading to global confusion.
Australian Labelling Guidelines
In Australia, coconut is not classified as a tree nut for labelling purposes. Coconut appears on ingredient lists but is not highlighted as a nut allergen.
