Nut Allergies

A nut allergy is an immune system reaction to proteins found in certain types of nuts. When a person with a nut allergy consumes a nut or comes into contact with nut proteins, their immune system may overreact and release chemicals such as histamines, which can cause allergic symptoms such as hives, swelling, and difficulty breathing.

The specific proteins that cause allergic reactions in people with nut allergies vary depending on the type of nut, but some common allergens found in nuts include:

1. Almond: Pru du 3 and Pru du 4
2. Brazil nut: Ber e 1 and Ber e 2
3. Cashew: Anacardin and Ana c 1
4. Hazelnut: Cor a 1 and Cor a 2
5. Peanut: Ara h 1, Ara h 2, and Ara h 3
6. Pecan: Carya al1 and Carya al2
7. Walnut: Jug r 1 and Jug r 2

It is important to note that nut allergies can be severe and can sometimes cause life-threatening reactions, known as anaphylaxis. If you or someone you know has a nut allergy, it is important to avoid consuming nuts and to carry epinephrine (also known as an EpiPen) in case of accidental exposure. There is currently no known cure for nut allergies, and the best way to manage a nut allergy is to avoid consuming nuts and to be prepared for accidental exposures.

Some people with nut allergies may be able to tolerate small amounts of nuts or nut products that have been cooked or baked, as the heat may alter the proteins that cause allergic reactions.

Nut allergies can affect people of all ages, but they are most common in children. Children with a family history of allergies, such as asthma or eczema, may be at higher risk of developing a nut allergy. Children with nut allergies are also more likely to have other allergies, such as allergies to other types of food or to environmental allergens such as pollen or pet dander.
