What should you know about pollen food allergy?

The immune system recognises similar proteins in pollen and a food. Symptoms are commonly limited to the mouth and begin quickly with raw produce; cooking may alter the proteins enough to reduce the reaction. An itchy throat can occur, but symptoms may also include tingling lips, an itchy mouth or mild swelling.

This pattern differs from a food allergy that can affect several body systems. A clinician can help distinguish the two from your history, the food involved and the timing of symptoms. Read more about Food Allergy and Itchy Throat.

Keep a note of the food, whether it was raw or cooked, how much you ate, and the symptoms and timing. Avoid the suspected raw food until you have received individual advice, and do not test it again on your own. Arrange an allergy assessment if reactions recur or interfere with eating.

Allergy Testing may include skin or blood testing, but results need to be interpreted alongside your symptoms. Ask whether related foods need avoiding and whether you need an emergency action plan.

Seek emergency help immediately for trouble breathing, wheezing, throat tightness, difficulty swallowing, faintness, confusion, or swelling of the tongue or face. These can signal Anaphylaxis. If you have prescribed adrenaline, use it as directed and follow your emergency plan; urgent assessment is still needed.

Could this be pollen food allergy or another food reaction? Which pollen and foods fit the pattern? Is cooked food likely to be tolerated? Do I need Allergy Testing or an emergency plan?
