LEAP Mediator Release Testing (MRT) for Food Sensitivities

LEAP stands for Lifestyle, Eating, And Performance.

The LEAP diet is called MRT which stands for Mediator Release Testing and is an ImmunoCalm Nutrition Program and with it, a specially trained Registered Dietitian can help you to reduce or eliminate symptoms due to food or chemical sensitivities, have a healthier lifestyle, well-balanced nutrition, and optimum performance.
LEAP has helped thousands of individuals with food and chemical sensitivities quickly and substantially improve. Some individuals have found they can successfully eliminate chronic health problems when they follow their LEAP diet. If your symptoms are related to your diet, then you need a dietary approach to address these symptoms.

Food & Chemical Sensitivities

Food and chemical sensitivities can result in an immune system reaction with the release of mediators which cause pain and inflammation in the body. The immune system has a first line of defense in which it identifies “self” and “non-self.” This is very beneficial for protecting us from unwanted bacteria and viruses. However, if the immune system decides that a food or chemical is dangerous and should be destroyed, the result is the release of mediators which cause inflammation and pain. This is how food and chemical sensitivities develop.

Many chronic conditions may be made worse by food and chemical sensitivities. Examples include, but are not limited to, Irritable Bowel Syndrome (IBS), Migraines, Fibromyalgia, Crohn’s disease, Ulcerative Colitis, Gastroesophageal Reflux Disease (GERD), Arthritis, and Autism Spectrum disorders. The following symptoms are often associated with food and chemical sensitivities –

  • Diarrhea, Abdominal Pain, Bloating, Distention, Gas, sometimes Nausea & Vomiting
  • Heartburn or Gastroesophageal Reflux Disease (GERD)
  • Migraine Headaches and Headaches other than Migraine
  • Muscle or Joint Pain, Aching, or Stiffness
  • General Malaise (feeling lousy), Fatigue, Sleepiness During the Day
  • Restlessness, Irritability, Depression, Anxiety, Mood Swings
  • Sinus Pain, Runny Nose, Stuffy Nose, Post Nasal Drip, Sore throat
  • Skin conditions such as Eczema and Dermatitis
  • Auto-immune disorders

Individuals with food and chemical sensitivities benefit from avoiding the foods and chemicals that trigger pain and inflammation. Keeping a food intake diary and logging symptoms is of little benefit in detecting food sensitivity because the onset of symptoms may be up to 3 days after ingestion of the offending food. Food sensitivity is a dose dependent reaction, meaning that an individual may not have a sensitivity reaction if a very small amount is consumed, and the size of the offending dose varies from one individual to the next. The delayed onset of symptoms and the dose dependent nature of food sensitivities makes sleuthing trigger foods difficult. There is a blood test available to make determining food triggers much easier and it is called the Mediator Release Test (MRT).

What is the MRT?

MRT stands for Mediator Release Test.  MRT is a blood test that checks your immune system response (or non-response) to 150 foods and chemicals. MRT is a functional live cell analysis that identifies foods and chemicals which provoke the release of mediators that cause pain and inflammation. The results of the blood test are used to create an individualized healthy eating plan (the LEAP diet) for significantly reducing or eliminating symptoms.  The specially trained Registered Dietitian then works with you, teaching you how to eat using the LEAP protocol, and sleuthing out any potential allergies or intolerances that may also be present.

MRT Accuracy

A blinded peer reviewed scientific study showed MRT to have the highest level of accuracy of any food sensitivity blood test:  94.5% sensitivity and 91.8% specificity.

Once I start the LEAP diet, how long will it take before I notice results?

Most patients see a noticeable difference within the first one to two weeks on the program. However, in some cases it can take as long as four to six weeks. Your particular response may vary depending on certain factors –

  1. How closely you follow your LEAP ImmunoCalm Nutrition Plan. If you follow it by the letter, you will have the greatest chance of success in the shortest time frame possible. If you follow it loosely or carelessly, your results will be compromised to the extent of your neglect. Out of all the factors, your compliance has the highest bearing on the benefits you will experience.
  2. How long-standing your condition has been. Sometimes it takes a bit more time to reverse the damage caused by years of sensitivity reactions, improper eating and/or inadequate nutrition. The vast majority of our patients experience great results within two weeks to one month of following their program closely.
  3. The degree to which food sensitivity plays a role in your condition. Some of our patients come to us and experience total symptom relief from their condition as long as they stay on their plan. Others will experience a decrease in symptoms but not complete remission. This is because food sensitivity can either be the direct cause OR a contributing factor to your health problem.
  4. Other factors such as medications can also be a factor.  An example is nexium for reflux symptoms contains polysorbate 80 and if you are sensitive to polysorbate 80 then that may be adding to your symptoms or complaints.
