Food Sensitivities or Intolerance

Food sensitivity or intolerance is defined as clinical gastrointestinal (GI) reaction with unknown immunological link.  This is in contrast to a food allergy, which is defined as reproducible symptoms that occur after the ingestion of a specific food.


The causes of food sensitivities or intolerances are:

  • Most young patients with food allergies are sensitive to potent allergens (eg. eggs, milk, peanuts, soy)
  • Older patients with food allergies may react to potent allergens and other foods (especially shellfish)
  • Food additives such as MSG (monosodium glutamate)


The most commonly experienced signs and symptoms of a food sensitivity or intolerance are:

  • Initially eczema alone or in association with GI symptoms
  • Asthma and allergic rhinitis (runny nose due to allergies) that may be aggravated by specific foods


The following diagnostic tools may be used to determine a food sensitivity or intolerance:

  • Skin allergy test
  • IgG and/or IgE testing
  • Elimination and reintroductory challenge diet
