Protein found in fruits and vegetables may cause oral allergy syndrome causes itching in the mouth when a particular fruit or vegetable is eaten.
In some people who suffer hayfever allergy symptoms, their immune system may treat proteins found in some fruits and vegetables the same way that it treats proteins found in pollen. The result is a condition called oral allergy syndrome. Oral allergy syndrome causes itching in the mouth when a particular fruit or vegetable is eaten. Some people may suffer from oral allergy syndrome all year round, but it is more common during allergy season when pollen levels are high.
The main treatment for oral allergy syndrome is to avoid foods that trigger your symptoms. Cooking destroys the proteins responsible for the allergic reaction, so the same foods that cause symptoms when eaten raw are often tolerated when cooked. People who cannot eat uncooked fruits and vegetables may need to rely on well‐cooked food in combination with vitamin supplements. However, it’s always best to seek medical advice before changing your diet. If you love a particular food and find it difficult to avoid, you can try peeling it as most of the responsible proteins are in the skin. Buying canned varieties may also be an option, as canning destroys the proteins as well.
