Food Inflammation &
Leaky Gut Testing

What is Food Inflammation Testing?


Food Inflammation Testing (FIT) measures how your body responds to foods, colors, and additives (including Candida).  The test measures IgG antibody responses and immune complexes when exposed to common foods. This differs from food allergy testing which tests for IgE antibody responses to foods.

Elevated IgG levels are one of the main causes of leaky gut syndrome and of systemic inflammation.  Systemic inflammation is often an underlying cause of chronic pain and health issues and it can even contribute to mental health issues. 


Why Should I Chose FIT Testing?


The FIT uses a multi-pathway testing to measure inflammatory pathways instead of IgG alone. This helps to eliminate false positives that often occur with traditional IgG testing. Each sample is run with15 standards and controls. 

What is Leaky Gut (Zonulin) Testing?

Leaky Gut Syndrome or increased intestinal permeability means that the lining of the digestive system is damaged. The damage leads to larger substances being absorbed through the intestinal walls.  Normally a healthy intestinal wall will allow water and nutrients to pass through to the bloodstream and protect the body from harmful substances. An unhealthy or leaky intestinal wall will also allow bacteria and toxins to pass through.

Zonulin is a protein that is synthesized in intestinal cells and liver cells. It is a key biomarker for intestinal permeability and is the only regulator of intestinal permeability that is reversible.

Why Should I Chose Leaky Gut (Zonulin) Testing?

Zonulin is one of three ways the FIT test can diagnose a leaky gut, along with finding a sensitivity to Candida and multiple Food Sensitivities. 

Zonulin Testing is best performed with your first FIT Test to provide a baseline for the Zonulin levels. This gives you the opportunity to track your progress after implementing an elimination diet based on the FIT Test results

Elevated levels of Zonulin are associated with systemic inflammation, digestive issues, and autoimmune diseases. Recent research also shows a connection to mental health through the enteric nervous system and the gut-brain axis.
