Citrus Intolerance Guide

Cirtus intolerance guide

Citrus is the combined term used for a genus of flowering trees and shrubs in the rue family (Rutaceae). These plants produce edible

citrus fruits that are eaten fresh after peeling the bitter rind.

Citrus fruits are also commonly juiced and used to complement soft drinks and alcoholic beverages, while the more bitter fruits are used in jams and preserves with sugar to adjust the taste.

Citrus intolerance or sensitivity

Citrus fruit sensitivity or intolerance is where a person presents various digestive symptoms after the consumption of citrus-derived products. A less severe condition than an allergy, this condition can still be uncomfortable and embarrassing for the individual. Take our test to find out if you have a citrus sensitivity.

Citrus intolerance symptoms

The common symptoms include:

Bloating.
Diarrhoea.
Tiredness.
Heartburn.
Acid reflux symptoms.
Gas.

Citrus allergy

Allergies to citrus fruits are rare because the ingredient present in them, citric acid, is a simple molecule and the body doesn’t produce antibodies that would trigger any allergic reactions to it.

However, the allergy is sometimes seen in people who have similar pollen allergies, which is known as cross-reactivity. People who are allergic to grasses in particular, may experience allergy symptoms to citrus fruits.

A 2013 study of 72 children and young adults with grass pollen allergies studied exposure to fresh lemon, orange, and clementine with a prick test. It found that 39 per cent of the participants who were allergic to pollen also had sensitivities to citrus.

39% of people who are allergic to pollen also have sensitivities to citrus.

Natural vs synthetic citrus allergy

Natural citric acid is extracted from fruits, while synthetic citric acid is the natural acid that is chemicalised commercially. One thing to note here is that if you only react to citrusy fruits, it could be an indication that you’re allergic to the fruit, not the citric acid.
