What is Salicylate Intolerance?
Salicylate (suh-lih-suh-late) intolerance or salicylate sensitivity is when the body has a reaction to salicylates, but it does not involve the immune system.
Salicylate is a natural chemical found in plants which use it as a preservative to protect themselves against disease, bacteria fungi and insects. The synthetic form of salicylate is acetyl salicylate (aspirin). The amount of salicylate in plant-based food is lower when compared taking a moderate dose of aspirin.
In people who are sensitive to salicylate when they eat foods that contain salicylates they may have symptoms of: nasal polyps, bronchial asthma, rhinitis, gastrointestinal inflammation, diarrhea or hives. They also need to avoid medications and skin products that contain salicylate including aspirin, bismuth subsalicylate, choline salicylate, diflunisal, magnesium salicylate, and salsalate.
Although salicylate may cause issues for some people there is recent research looking at the beneficial effects they may have within the body.
What is a Low Salicylate Diet?
A low salicylate diet means that you carefully eat foods that contain no salicylate or that are low in salicylate, and you avoid high salicylate food. This diet may reduce symptoms of salicylate intolerance.
Usually you start by eliminating foods that containing salicylates, then reintroduce foods slowly to identify whether salicylates are tolerated and what level they are able to be consumed without causing symptoms
If you are exploring a low salicylate diet it is important to consult registered dietician as by removing or reducing fruit and vegetables from your diet may cause deficiencies in vitamins, minerals and other nutrients.
Currently there are no peer-reviewed studies supporting the use of low salicylate diet in children, and due to the risk of negative outcomes including nutritional deficiencies, eating disorders or food aversion issues a low salicylate diet in children is not often recommended.
There are currently no standard tests to diagnose salicylate intolerance.
Many studies have be done to report the levels of salicylate in different foods, however the results remain variable due to differences in testing methods, where the products come from, type of food processing and storage. For this reason food lists should be used as a general guide.
