Food allergies are uncommon triggers for asthma. Certain foods—such as wheat, shellfish, eggs, dairy, soy, peanuts, foods containing salicylates (like tomatoes, cucumbers, or kiwi), and some food additives— can occasionally worsen asthma symptoms, but this is rare. If you suspect specific foods may be causing symptoms, consult your doctor before eliminating anything from your diet. If you have anaphylaxis this could trigger a severe asthma attack.
Trigger tips:
- If you think food or drink might be triggering your asthma, see your doctor who may refer you to a specialist or for allergy testing.
- Don’t remove any food from your diet before an allergy is confirmed by medical testing.
- If your asthma is triggered by a certain type of food check the labels on food before eating and ask staff about ingredients when eating out.
