What actually is hazelnut? Is it a tree nut? Allergies to tree nuts tend to be very serious, causing life-threatening and sometimes deadly reactions. If you have tree nut allergies, you may also suffer from reactions triggered by different types of nuts, even though they don’t come from related plant species.

Hazelnut is considered a tree nut and hazelnut allergy is one of the most common tree nut allergies. Hazelnuts, like other types of tree nuts, can cause food allergy symptoms that range from moderate to severe.

In this article, I am going to tell you more about the symptoms and treatments of hazelnut allergy. You can find out more on our other blogs on Hazelnut allergy symptoms and treatments, How to Choose and Store the Best Hazelnuts, Hazelnuts FAQs and How to peel hazelnuts.

Is Hazelnut a Tree Nut?

The Hazelnut is the nut of the hazel tree, so, it’s categorized as a tree nut, together with nuts such as cashews, almonds, Brazil nut and pecans. Although tree nuts are similar, they come from different and irrelevant nut families. Hazelnut belongs to the birch family, as do the filbert and hickory nut. If you’re allergic to hazelnuts, you might also be allergic to the other birch nuts but might not be allergic to the other tree nut families.

What is a hazelnut allergy?

What is a hazelnut allergy?

Hazelnut allergy is a result of an immune reaction that attacks proteins in the nut. This triggers the production of immune chemicals, including histamine and antibodies, that causes the typical symptoms of allergic reactions. To prevent a reaction, avoid exposure to hazelnuts and other nuts that may trigger the allergy. Ask your doctor if you suspect you are allergic to hazelnuts.

There is also a milder kind of tree nut allergy which is associated with birch pollen allergy, where symptoms are mainly confined to the mouth, inducing a condition called “Oral Allergy Syndrome” (OAS). This allergy is triggered by molecules found in tree nuts which are very similar to pollen allergens. These molecules tend to be killed by cooking, which can decrease the allergenicity of nuts for these allergic consumers.

Reactions to hazelnuts can also occur as a consequence of hidden hazelnut ingredients or traces of hazelnuts in a product. So, you should always take a look at the product labeling before consuming any products to make sure they do not contain any hazelnut ingredients.

Hazelnuts Allergy Symptoms

Hazelnuts Allergy Symptoms

Allergy to hazelnut is usually found in patients with hay fever and tree pollen allergy. These patients typically present with these symptoms after the ingestion of hazelnuts or hazelnut containing products:

  • Itching
  • Swelling
  • Burning in the mouth and throat

This so-called “oral allergy syndrome” or food-pollen allergy is caused by cross-reactivity between tree pollen allergens, especially alder, birch, hazel pollen and hazelnut proteins.

In addition to the “oral allergy syndrome,” rigorous allergic reactions to hazelnuts are reported in patients without any association to tree pollen allergy. These people usually display:

  • Hives (urticaria) or eczema on your skin
  • Swelling of the lips and face (angioedema)
  • Breezing difficulties (asthma or swelling of the throat)
  • Vomiting, nausea
  • Diarrhea, abdominal pain
  • Wheezing, coughing or a runny nose
  • Anaphylactic shock – A serious allergic reaction that needs immediate medical care.

If you have an allergy to hazelnuts, these symptoms mentioned above can occur in two hours after consuming hazelnuts or food containing them.

There is no actual cure for hazelnut allergy. You should Manage your hazelnut allergy only by avoiding hazelnuts and being ready for future reactions.

Talk to your allergist or doctor if you have any unusual symptoms after eating or touching hazelnuts. You may require allergy testing to determine the severity of your reaction, or to find out if you have allergies to other nuts.
