Fruit allergy is a very common food allergy. Learn about its symptoms, how it is diagnosed, and what the most commonly prescribed medical treatment is.

They are very common -and therefore known – specific food allergies, such as allergies to egg, the protein allergy fish, or soy allergies. However, did you know that a fruit allergy is also quite common? In fact, according to the Spanish Association of Allergy to Food and Latex, the percentage of allergic reactions corresponding to fruits in adults is 37%, while the percentage of these reactions in children is 11%.

It is, as you surely know, a group of essential foods in our diet and daily diet, mainly due to its fiber, vitamin and mineral content.

However, like other foods, fruits present in their composition with some substances and components that can trigger allergies in people sensitive to them.

As we already mentioned in the article on the differences between food allergy and intolerance, food allergy appears when the immune system (in charge of defending our body from external aggressions), interprets that a certain food, or additive contained in it, is an invader. This causes a disproportionate immune response, causing the allergic reaction. In it, the body releases a series of chemical substances, among which we can find histamine.

In the case of fruits, the main allergens present in them are proteins that our immune system identifies as harmful and therefore dangerous components.
