We now offer Zonulin Testing in addition to Food Sensitivity testing.



(Takes 2-3 weeks for results)

Food sensitivities affect more than 100 million people worldwide! Food sensitivities cause a range of illness and symptoms, including skin rashes, intestinal symptoms, fatigue, depression and pain.

The Food Inflammation Test evaluates the most common foods and additive sensitivities. Measures both IgG and Immune Complexes, the most common food-related pathways in the body. It takes a simple finger prick, apply to the blood spot to the test sheet and send your sample in for testing. In a couple of weeks, you can know what is causing sensitivities and inflammation in your body.

Are you experiencing aches and pain, fatigue, anxiety and depression, bloating or having abdominal pain? The FIT test allows you find the foods and either clear them with AACT (Accelerated Allergy Clearing Technique at Nourish and Revive) or eliminate the foods causing the reactions. Nourish and Revive specializes in natural allergy solution and focuses on nutrition and creating a health plan to help you reach your health goals.



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. 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. It is estimated that anywhere between 50 and 100 percent of food intolerance sufferers have increased intestinal permeability.

Increased intestinal permeability can be caused by food allergies and sensitivities, stress, infections, and low stomach acid, among other causes. Elevated levels of Zonulin are associated with Celiac Disease, Autoimmune disease, and Multiple Sclerosis, in addition to other chronic illnesses.

In a healthy gut, there are healthy cell junctions and good nutrient absorption. In a leaky gut, however, the Villi are damaged, there is poor absorption and the cell junctions are loose. This means that bacteria and unwanted items can pass through the gut, as seen in the picture to the right.

Zonulin Testing is best performed with the patient’s first FIT Test to provide a baseline for the Zonulin levels. This gives patients the opportunity to track their progress after implementing an elimination diet based on the FIT Test results. We recommend retesting when you retest your FIT.
