What are Food Sensitivities?

Food sensitivities are not food allergies. Food sensitivity testing is different than allergy testing.  With food allergies, you will have an immediate physical response. For instance, if you are allergic to peanuts and eats peanuts, you will experience a serious, life-threatening reaction.  Food sensitivity testing helps you with the following conditions.  The reason to test for food sensitivities is to help you more quickly identify your food allergies and feel better as soon as possible.  Most people with food sensitivities have multiple symptoms and reactions. Here are conditions commonly associated with food sensitivities.

The following conditions are often associated with food sensitivities:

  • Irritable Bowel Syndrome (IBS)
  • Chronic Diarrhea
  • Cramping
  • Heartburn
  • Headaches
  • Migraine
  • Fibromyalgia
  • Muscle Pain
  • Joint Pain
  • Fatigue
  • Autism
  • Attention Deficit Disorder

If you suffer from any of these conditions our Food Sensitivity Testing program may finally give you the answers and a solution to your problems.

Did you know at food sensitivities are related to your immune system?

Most of your immune system is located in your gut.  So tummy troubles are common when your immune system is stressed.  Ever hear of the expression “sick to your stomach” or “something is hard to stomach”.  There is a strong connection between your brain and your gut and you may find that you have even more food intolerances during periods of stress like during COVID-19.

Are you tired of suffering with the relentless symptoms of IBS, migraines or fibromyalgia pain?

If you are reading this, you have probably heard of MRT Mediator Release Testing, MRT food sensitivity testing or MRT/LEAP testing. Are you ready to take a positive step to help you discover and manage your food sensitivities? Food Sensitivity Testing can help.

What is MRT Mediator Release Testing?

Are you struggling with debilitating symptoms that are keeping you from enjoying the things that are the most important to you? Have you missed days at work or school or turned down social events because of the pain of migraines, IBS or arthritis? We can help you get back out there with MRT/LEAP food sensitivity testing!  It is so rewarding to be able to offer my clients a better quality of life. For them to start feeling better and living their life on their terms.

To do this I work with the team at Oxford Biomedical Technologies, which is the lab that provides the MRT (Mediated Response Test). This is a blood test that tests for 30 chemicals and 120 foods to determine your level of food sensitivities to these items.

From these results we create your LEAP protocol, which is an elimination diet like no other. It uses your results to create a plan to eliminate the triggering foods and get your body back to health.

We start with your least reactive foods and continue to add in foods to confirm they are safe for you. The end goal is to get you back to a varied diet, free from symptoms. 

What exactly is MRT/LEAP?

MRT (Mediator Release Test) is the blood test component that measures the inflammatory reaction to 170 foods and chemicals.

LEAP (Lifestyle, Eating, And Performance) is the process of using these results to treat unwanted symptoms using a personalized elimination diet based on your specific blood results.

Your CLT (Certified LEAP Therapist) will guide you through your results in order to greatly reduce or eliminate the unpleasant symptoms you may be suffering with.

Our team of Registered Dietitians designed a cookbook on how to focus on what you CAN eat during the initial phases of this individualized elimination diet. See below for our Cooking with Food Sensitivities Survival Guide.

Here is the procedure of MRT food sensitivity testing:

To do this, you complete a blood test that tests for 30 chemicals and 140 foods to determine your level of food sensitivities to these items. From these results we create your LEAP protocol, which is an elimination diet like no other.

It uses your results from your least
reactive foods to create a plan in eliminate the triggering foods and get your body back
to health. The end goal is to get you back to a varied diet with minimal symptoms.

Steps involved in process:

  1. Meet with your Registered Dietitian to evaluate if this testing is a good option for you!
  2. Join us on our monthly blood draw to get the blood work taken.  We have a certified phlebotomist in our Greenbelt or Columbia office monthly.  Your dietitian can schedule you for this at your initial appointment.
  3. Results typically come back to us within 10-12 days, our office will alert you when we have received them in order to follow up for an appointment to discuss your results. You will be given multiple copies and we urge you to share with your doctors!
  4. Follow-up nutrition counseling sessions in office or by phone (review of results and guidelines, meal and menu planning, grocery shopping, eating out).

What do results look like?

The MRT will identify the foods that cause reactions for YOU.   It is done with a simple blood test and results are available in 10-14 days. Your results will show the reaction levels for 30 chemicals and 140 foods.

How do I use the food sensitivity results?

With the help of the testing we will start you eating your least reactive foods and about 80% of people will have their symptoms greatly reduced. In time we continue to add foods back into your diet to get you back to the most variety possible with the exclusion of the foods that make you sick.

  • Give recommendations on products and where to purchase them that fits within your LEAP diet.
  • Meal planning with phase appropriate foods.
  • Teach you new methods of meal prep and meal planning.
  • Scrutinize food/symptom logs for links between foods and unwanted symptoms.
  • Incorporate other nutrition therapies for overlying conditions (SIBO (Small Intestinal Bacterial Overgrowth), lactose intolerance, fructose intolerance, food allergies etc.)
  • Access to LEAP mentor and CLT community for ideas to further support you!

Food Sensitivity Testing

When will you feel better?

Most people will see a drastic improvement in their symptoms in the first 7 days of the
elimination diet. Long standing issues with food sensitivities or conditions like
fibromyalgia/migraines may take more time to see complete symptom improvement such as
14-21 days. If there is no improvement at all in the first 7-10 days, your CLT will have to
troubleshoot your food diary and any confounding factors such as medications.
