What is the LEAP Test for Food Sensitivity and How Does it Work?

The MRT LEAP food sensitivity test is a personalized approach to reducing inflammation! If you suffer from chronic health issues like migraines, IBS, or eczema, you may have a food sensitivity that's causing inflammation in your body. The LEAP test is an inflammatory food test that can help identify trigger foods and create a personalized diet plan to reduce symptoms and improve your overall health.

 This anti-inflammatory diet uses a blood food sensitivity test to identify foods, additives, and chemicals that are causing immune reactions, then re-builds your diet based on your best foods.   The end result of this program is reduced inflammation, reduction of symptoms, and an improved quality of life. 

Learn more about how the LEAP test works and its potential benefits here.

What are food sensitivities?

Food and food-chemical sensitivities are highly complex non-allergic (non-IgE), non-celiac inflammatory reactions - and they're one of the most important sources of inflammation and symptoms across a wide range of chronic inflammatory conditions.  It is often very challenging to identify inflammatory foods because symptom manifestation may be delayed by many hours after ingestion, and reactions may be dose-dependent. Food sensitivities can play a role in countless diseases, including but not limited to IBS, migraine/headache, Fibromyalgia and Chronic Fatigue Syndrome.

How do I determine my food sensitivities?

Using the Mediator Release Test (MRT®) takes the guesswork out of an elimination diet and gives you information you cannot get any other way - and that information is the foundation for fully addressing food sensitivities and achieving the maximum outcomes in the shortest period of time.  It is a functional measurement of diet-induced sensitivity pathways.  Not only does the test give insight into inflammation provoking foods and food-chemicals, it more importantly identifies our BEST foods - the foods that form the basis of your eating plan

How do I treat my food sensitivities?

The anti-inflammatory LEAP diet is designed to remove all possible dietary provocation quickly, without guesswork, by utilizing the MRT® test results over the course of approximately 90 days.  We begin with the "safest" tested foods and gradually reintroduce more non- or low-reactive safe foods over time, with a focus being on what you can have, not what you cannot have.  


Once the inflammatory foods are removed, the emphasis is on replacing necessary nutrients, reinoculating good bacteria, and repairing the gut lining.  These steps are critical in calming your immune system and reducing inflammation.  This diet provides patient-specific meal ideas and other lifestyle-change support for building a healthy diet designed to alleviate food-sensitivity related symptoms.

What are the benefits of taking the LEAP test?

The benefits of taking the LEAP test are numerous. By identifying inflammatory foods that may be triggering inflammation in your body, you can create a personalized diet plan that can help reduce symptoms and improve your overall health. This can lead to a reduction in chronic health issues like migraines, IBS, and eczema, as well as improved energy levels, better sleep, and a stronger immune system. Additionally, the LEAP test can help you identify foods that you may be sensitive to but not aware of, allowing you to make more informed choices about your diet and potentially avoid future health issues.

I could not be happier with the cholesterol results... Anyway I just want to share these results and say thank you, thank you, thank you for showing me a new way to live, a healthy way to live that I did not know existed.

Nelle in Harrisonburg, VA

This has been the missing component for years in my healing that has allowed cyclical relapse and chronic fatigue to plague me.  If you've been trying to eat better and are eating whole foods, chances are you've got sensitivities. I'd like to recommend the MRT and LEAP protocol for you.  I recommend my RD, Stacie Haaga.

Wanda in Hagerstown, MD

Since I started the MRT/LEAP protocol, I have been feeling fabulous. My doctor has been overwhelmed with my progress. I was taken off of all my blood pressure medications. I have lost over 70 pounds and am moving well. There is very little inflammation in my joints and have been discharged from physical therapy. 

How do I get started with the
Food Sensitivities program?

Ideal candidates for these programs...

  • Have experienced symptoms of food sensitivity

There are three food sensitivities programs available with details below- Take the LEAP Self-Paced virtual program, Diet Reset and the Restore Your Health program.  An initial 15 minute phone consult is recommended at no charge to determine which program is best for meeting your health goals. 

Most patients begin to see results in two weeks however, occasionally patients take longer than 90 days to heal due to underlying health conditions. Those conditions may be addressed through additional consultations in coordination with or at the conclusion of the program.  Further consults are available for additional support.
