​Registered Dietitian Nutritionist and Certified Diabetes Educator

Lifestyle Eating And Performance (LEAP) is an individually designed eating plan based on the results of your MRT food sensitivity blood test.

As a Certified LEAP Therapist, Meredith will combine the results of your test with her clinical training to implement the LEAP diet protocol.

She will design a specific diet of your KNOWN non-reactive/non-inflammatory food. She will then systemically guide you as you re-introduce untested food. This targeted diet protocol can improve your symptoms and change your life.

 Food sensitivities are related to a wide range of symptoms and chronic health problems including irritable bowel syndrome, migraine and other headaches, excess mucous production, hives, eczema, fibromyalgia and chronic fatigue syndrome.

Food could be making you sick.

Here is a list of the food and food-chemicals tested in the MRT:

Do you think food is making you sick?​

You haven’t been able to figure it out. You avoid certain food but still don't feel quite right. You’ve tried many remedies and seen several doctors but still don’t have the answer.

Food sensitivities are an under-diagnosed source of inflammation 


MRT also quantifies the degree of the inflammatory response. The results show your level of reactivity from lowest to highest which is crucial in developing your LEAP diet plan.


Attention New York State residents:
New York has a law requiring blood drawn in New York to be analyzed by a lab in New York. Since the MRT lab is located in Florida, New Yorkers must head out of state to get their blood drawn and shipped to this lab. New York is the only state out of 50 with this requirement. There are plenty of MRT- friendly labs in states bordering NY that can draw and ship your blood.  Talk to Meredith about finding a lab near you. 

The Mediator Release Test (MRT) is the most comprehensive food sensitivity test available. It is a blood test that reveals YOUR inflammatory response to 120 different food and 30 different food-chemicals. When blood is exposed to a food or food-chemical, there is either an inflammatory response or not. If your blood reacts, it indicates a sensitivity to that particular food or food-chemical.
