Food Sensitivity Testing

What are food sensitivities?

Food sensitivities are delayed reactions to specific foods that are triggered by IgG antibodies (cells that belong to our immune system).
In a food sensitivity reaction, IgG antibodies bind to the food antigen (essentially the food protein) and create an antibody-antigen complex. These complexes are normally removed by special cells called macrophages.  However, if they are present in large numbers and the reactive food is still being consumed, the macrophages can’t remove them quickly enough.  The food antigen-antibody complexes accumulate and are deposited in body tissues. Once in tissue, these complexes release inflammation causing chemicals, which may play a role in numerous diseases and conditions.


How long does it take to get food sensitivities?

Food sensitivity typically takes months to develop and can be present for years before it is detected. As the antigen-antibody complexes accumulate and deposit in tissues, the body mounts an inflammatory response that is implicated in many different symptoms.


Health conditions that may be linked to food sensitivities

  • Digestive concerns including nausea & vomiting, diarrhea, constipation, irritable bowel syndrome (IBS), abdominal pain, gas and bloating
  • Skin symptoms that might include itching, redness, swelling, and rashes (including eczema, psoriasis)
  • Brain & mood symptoms including memory disturbances and behavioural problems
  • Bronchitis and asthma symptoms
  • Musculoskeletal Joint pain, muscle stiffness and swelling
  • Fatigue, weakness


Should I get tested for food sensitivities?

Patients can experience immense symptom relief and health optimization when IgG reactive foods are removed from the diet. Food sensitivities have been linked to a variety of conditions.

Have you ever had the feeling that your symptom(s) were linked to eating a particular food, but you just couldn’t put your finger on what?

Because IgG food sensitivity reactions take hours or days to develop, and we are typically eating multiple different foods in combination, it can be very difficult to determine which food is responsible for your reaction without testing.
