What should you know about fare food allergy?

A reaction may cause hives, facial swelling, vomiting, stomach pain, wheezing or an itchy throat. The severity of a previous reaction does not reliably predict the next one. Food allergy is different from an intolerance, which does not involve the same immune mechanism. A clinician can review what you ate, how quickly symptoms appeared and whether another illness or medicine could explain them.

Assessment may include a careful history and selected allergy testing. Avoid removing many foods without guidance, because unnecessary restriction can affect nutrition and make daily eating harder.

Keep a record of suspected foods, ingredients, timing and symptoms. Read labels, ask about shared cooking surfaces and tell schools, carers or restaurants about the allergy. Follow the action plan provided by your clinician and keep prescribed emergency medicine accessible. Allergy testing should be interpreted alongside your history rather than treated as a diagnosis by itself.

Call emergency services immediately for trouble breathing, throat or tongue swelling, collapse, severe dizziness, or symptoms affecting more than one body system after eating. These can signal anaphylaxis. Use prescribed emergency treatment according to your action plan while waiting for help, and do not rely on an antihistamine alone for breathing or circulation symptoms.

Which food or ingredient is most suspicious? Do I need allergy testing? What should my written emergency plan say? Who should be trained to use my prescribed device? Which foods can I eat safely while assessment is ongoing?
