Food Sensitivity Testing (MRT)

Is your food making you sick?

Are you suffering from a stubborn health problem that won’t go away no matter what you try?

  • Migraines / Headaches
  • Fatigue
  • Bloating
  • Heartburn / Indigestion / Reflux
  • IBS (Irritable Bowel Syndrome)
  • Constant Runny Nose

Or perhaps the medications and treatments you’re taking aren’t actually getting at the root cause of your illness – but you want something that will? If you feel this way, or know someone that does, consider some important facts:

  • Medical research has shown that sensitivities to foods and food chemicals can be involved in a wide array of painful symptoms and chronic health problems.
  • If foods and additives in your diet are causing your illness, whatever medications you take will ultimately fail because they only mask the symptoms. They don’t treat the underlying cause of the symptoms. And, as is too often the case, many medications have side effects that can lead to other health problems.
  • If food sensitivities are causing your illness and  you don’t properly address them, you could easily end up suffering for many years, spending thousands of dollars for treatments that will never work.

What is MRT?

MRT stands for Mediator Release Test. The Oxford Laboratories MRT identifies your sensitivity to 120 foods and 30 food chemicals, additives, and colorings by using a patented blood test. Find out how the test works.

Even foods that are considered healthy such as chicken, pineapple, broccoli, or spinach can provoke symptoms in a sensitive person. So, you can be eating what you think is a very healthful diet while causing underlying damage to your body. And, reactions can be delayed or dose dependent. This means you may not feel the effects of a reaction until many hours or days after you’ve eaten the reactive foods, or unless you’ve eaten enough of the reactive food.

Although they are sometimes (incorrectly) used interchangeably, a food sensitivity is different than a food allergy or food intolerance.

Food Allergy

Perhaps the best known example of food allergy is also its least common and most dangerous. Anaphylactic shock is a severe hyper-reaction of the immune system caused by a massive release of histamine and other chemical mediators from certain types of white blood cells called mast cells and basophils. Not everyone with food allergies experiences anaphylaxis though. The immunological triggering mechanism that causes the mast cells (and basophils) to release their chemicals is called IgE and is a very well understood phenomenon. This underlying mechanism is considerably different from the triggering mechanisms found in food sensitivities. The most common foods implicated in food allergy are peanuts, other nuts, shellfish or foods containing sulfites. People with anaphylaxis can die within minutes if they ingest even one molecule of their allergic food.

Food Sensitivity

Food sensitivity (also known as delayed food allergy) is quite another story. Delayed reactions manifest in many different ways as they can affect any organ system in the body and can take from 45 minutes to several days for symptoms to become apparent. The delayed onset of symptoms and complex physiological mechanisms involved in food sensitivities make them an especially difficult puzzle to try to solve either on your own or with most laboratory serum tests. In fact, food sensitivities often go undiagnosed or misdiagnosed. The treatments prescribed usually provide only temporary relief that mask the symptoms instead of addressing the root cause of the problems.

The differences between the two kinds of immune-mediated adverse food reactions are summarized in the table below:

Food Sensitivities Food Allergies
Body Organs Any organ system can be affected Usually limited to airways, skin, gastrointestinal tract
Symptom Onset From 45 min up to 3 days after ingestion From seconds to 1 hour after ingestion
Acute or Chronic Usually chronic, sometimes acute Usually acute, rarely chronic
% of Population Affected 20 – 30% 1 – 2%
Immunologic Mechanisms White blood cells, Antibodies (IgA, IgG, IgM, C3, C4 IgE
Non-immunolgoic Mechanisms Toxic Pharmacologic None
Food needed to
trigger the reaction
From small to large amount; often dosage dependent 1 molecule

Food Intolerance

Food intolerance can produce some digestive symptoms that are similar to food sensitivity but it doesn’t involve the immune system. Instead, when the food in question is consumed, it is not properly digested and begins to ferment inside the gut. The best example of food intolerance is lactose intolerance. This condition is characterized by bloating, loose stools or diarrhea and gas. Lactose intolerance is caused by an inability of the body to produce enough of the enzyme lactase, which breaks down lactose, the primary sugar found in milk. Avoiding milk products or supplementing the diet with lactase enzyme is the best way for a person with lactose intolerance to overcome the problem.

Testimonial

I suffered from severe and frequent migraines and stress headaches for about the past 15 years… When I met Laureen I didn’t have much, if any hope left.. I had literally tried everything… but after talking with her several times and also meeting with her to discuss my health issues, she ordered some food allerrgy tests, and after analyzing all my info, she recommended several supplements, vitamins, and gave me the courage and willpower to eliminate many “bad” foods (sugar, caffeine, gluten, etc) from my diet. I’ve been headache free for over 3 months now, and have also been losing weight and inches, and feeling MUCH better overall! I give Laureen much of the credit for “turning my life around.
