7 Causes of Peanut Allergy

Genetic predisposition

Peanut allergy is often genetic, and people with a family history of allergies are more likely to get one.

Early exposure

Peanut allergies are more frequent in newborns and young children since their immune systems have not fully developed.

Sensitization to peanut proteins

As a result of an immune response to peanuts, the body may produce antibodies against peanut proteins.

Cross-reactivity

Individuals who are allergic to tree nuts such as almonds, Brazil nuts, and hazelnuts are more likely to develop a peanut allergy.

Other allergies

People who have other allergies, such as asthma or eczema, are more likely to develop a peanut allergy.

Exposure to peanut oil

Some people may be allergic to the proteins in peanuts, while others may be allergic to the oils used in peanut processing.

Age

Peanut allergies are most common in children, but can develop at any age.
