Allergy to nuts (nuts, cashews, pistachios, hazelnuts, sunflower seeds, etc.) is a common type of allergy in children and adults and is a reaction to the proteins contained in these fruits. It is rare that this allergy disappears over the years.
This allergy tends to persist when it occurs and is rare to disappear over the years. Also, those who are allergic to peanuts are more likely to develop an allergic reaction to nuts because the same proteins are found in both. The symptoms are similar to those caused by other foods and can vary from mild to severe.
