Frequently Asked Questions (FAQs)

Key points on food allergy

  • Food allergy is a reaction to a specific food or foods involving the Immune system and production of IgE immunoglobulin.
  • Symptoms can range from mild to severe and may involve the skin, gut, breathing or the whole body’s circulation system.
  • Diagnosis is made by measuring IgE levels.
  • Non-IgE mediated food allergy requires specialist diagnosis.
  • Reactions can often occur to trace amounts of foods so complete exclusion is essential.
  • Some people can tolerate a well-cooked version of the food but will react to the food in its part-cooked or raw state.

Key points on food intolerance

  • Food intolerance reaction delayed and symptoms may take several hours, or even several days to appear.
  • The immune system and IgE are not involved.
  • Multiple symptoms can occur ranging from migraine to bloating, diarrhoea, lethargy, joint pain and a general feeling of malaise.
  • Food intolerance reactions can also be caused by naturally occurring chemicals like histamine but also by food chemicals such as caffeine, salicylates and monosodium glutamate.
  • Even ingestion of small amounts of a culprit food can cause a reaction but usually larger amounts trigger large scale reactions – some people report they can tolerate a food if eaten once a week or in small daily portions but any more than this causes symptoms.

To help diagnosis

  • Seek specialist advice.
  • Keep a detailed food and symptoms diary.
  • Apart from lactose intolerance, which can be diagnosed by a GP, there are NO tests that are scientifically proven to diagnose food intolerances.
