We're pleased to announce that we now offer our complete report package in both English and French.

FIT in the news… and not in a good way

FIT in the news… and not in a good way

As much as we might hope otherwise, not everything in science or medicine is black and white, cut and dried, this or that.  And so it is with food intolerance testing. Is it science or, as a recent article questioned, science-ish?

Part of the issue is not the actual validity of the science that underpins IgG food allergy (type III) testing, it is the unsubstantiated claims made by some more unscrupulous purveyors of the tests. Bogus claims, and irresponsible food elimination recommendations, have completely undermined the very real positive impact that food IgG testing can have on patient health outcomes.

At FitLabs, we think it best to confront these issues in the press head on; to answer questions or address concerns; to acknowledge that informed debate is a good thing. And, that those who question the value of food sensitivity testing are doing so from a sincere position of patient well-being. 

That said, those who take a more holistic view of healthcare, and who embrace Naturopathy, can appreciate that food intolerance testing is not the only issue on which traditional medicine and Naturopathy diverge. They also have diverging opinions on the best course of treatment for:

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

Food sensitivity vs. food allergies

The fact is a food allergy triggered by the release of IgE antibodies is a potentially serious health condition and different, very different, from a food sensitivity triggered by IgG antibodies. The latter is not a disease, but it may play a role in causing disease or making certain types of symptoms worse.

Food sensitivity and IBS

Studies have linked improvement with IBS (Irritable Bowel Syndrome) patients after IgG reactive foods were removed from the diet. Indeed, several small studies have further shown that removing IgG reactive foods from the diet helps reduce the frequency of migraines. Overall, studies and anecdotal evidence has underscored a strong connection between IgG food antibodies and inflammation. This makes sense as food sensitivity is an immune process that leads to inflammation, which in turn, often plays a role in the painful symptoms of many health conditions. 


There is no doubt that food sensitivity is an evolving area of research. New studies, new learning, new processes on the role of IgG in food reactions are released every year. For us that scientific research is critical, because for us, working with health care practitioners to improve patients’ health outcomes is, at the end of the day, all that matters… because at FitLabs, results matter.
