About Food Intolerance

About FIT

Food intolerance or IgG food allergies (type III) is a growing concern among many patients and their health care providers. This is largely due to the difficulty drawing a straight line between certain foods and the chronic complaints that a food sensitivity might be causing. FitLabs’ test – exclusively sourced from ImuPro – helps overcome that uncertainty. 

With an IgG food allergy, the immune system reacts to usually harmless food allergens and produces specific IgG antibodies. These antibodies can then cause inflammatory reactions which may lead to various chronic complaints. However,  since these symptoms are often delayed for hours or even days, patient can often only suspect that a certain food is the source of their complaint, but the delayed onset makes it hard for them to be certain. 

FitLabs’ ImuPro test detects the levels of IgG antibodies directed against specific foods, which could be causing a type III food allergy, and possibly leading to the development of chronic symptoms. The reality is that even in the cases in which a patient is sticking to a healthy diet, type III food allergies can trigger low-grade inflammation which underlies many health problems including:

  • Migraines
  • Irritable Bowel Syndrome (IBS)
  • Crohn’s Disease
  • Excess weight
  • Skin problems

Food intolerance vs. food allergies

It’s important to note that: An IgG food allergy (type III) or food intolerance should not be mistaken for a classic food allergy (type I). In patients that have a type I allergy, their immune system produces IgE antibodies. These antibodies can lead to an immediate allergic reaction. The symptoms often appear within seconds or minutes: severe swelling, breathing difficulty, rash, itching skin or even anaphylactic shock.

What is FIT?

Food intolerance testing – also referred to as an IgG food allergy (type III) testing – is a laboratory test in which blood is analyzed to detect levels of IgG antibodies specific to particular food proteins. Performed in a highly specialized laboratory, the test results enable health care professionals to guide their patients who suffer from a wide variety of chronic complaints emanating from food intolerance.

Imu Pro

The test – developed by ImuPro and exclusively available in Canada from FitLabs – tests foods individually and allows the patients to change their diet very selectively based on their results. Along with the test results, FitLabs delivers comprehensive nutritional guidelines and professional support for you and your patients.
