  2. is often to specific foods. Common food allergies in adults include fish and shellfish and nut allergies. Common food allergies in children include milk, eggs, fish, peanuts and other nuts 
  3. is a reaction by your immune system (your body’s defence against infection).

  2. only results in symptoms if you eat a substantial quantity of the food (unlike an allergy, where just traces can trigger a reaction)
  3. does not involve your immune system – there is no allergic reaction, and it is never life-threatening
  4. can be caused by numerous diverse foods
