In 1994 I was diagnosed with celiac disease, which led me to create Celiac.com in 1995. I created this site for a single purpose: To help as many people as possible with celiac disease get diagnosed so they can begin to live happy, healthy gluten-free lives. Celiac.com was the first site on the Internet dedicated solely to celiac disease. In 1998 I created The Gluten-Free Mall, Your Special Diet Superstore!, and I am the co-author of the book Cereal Killers, and founder and publisher of Journal of Gluten Sensitivity.
Through his writings, we know that Hippocrates, the father of medicine, had already recognized the presence of allergic reactions in people as early as ancient times. However, the term allergy is a relatively new one, as compared to many other commonly used medical terms. In 1906, Viennese pediatrician Baron Clemens von Pirquet used the term for the first time to describe an altered response of his patients bodies. Von Pirquet believed that this altered reaction manifested itself in changes of the immune system, effected by external influences on the body, such as: food intake, the air breathed or direct skin contact. The term allergen (the substance responsible for the altered reaction) was born. At that point in time, however, von Pirquet had no means of scientifically proving that these immunological changes actually occurred in the body. It was not until the mid-1920s, that a second significant event occurred.
Researchers found that, by injecting a minute quantity of purified allergen under the skin, certain individuals would develop a clear skin response; a welt, with or without itching and redness, could be provoked. This positive skin test for allergies would show itself most prominently in patients with hay fever, asthma, chronic rhinitis, hives and eczema. The prick test became a method of demonstrating the involvement of the immune system in allergic reactions. However, the precise biological reason for the reaction continued to remain a mystery.
It was not until the Sixties, when an important discovery occurred which provided long-awaited scientific support for the classical allergy theory and removed any doubts about the relationship of the immune system with allergies. This breakthrough came about with the scientific discovery of immunoglobulin E (IgE) by a Japanese couple named Ishizaka.
Classical Allergic Reaction
The following are the chain of events which happen in allergic reactions:
Histamine is a chemical substance responsible for a great number of complaints which may arise during allergic reactions. It causes muscle cramps and an inflammation-like process with redness and swelling of mucous membranes.
reactions can occur under a variety of circumstances. For instance,
inhaling certain substances, such as grass pollen, house dust,
etc., may cause an allergic response. However, the consumption
of certain foods may do the same. Allergies typically bring
on complaints very rapidly upon contact with the allergen. Complaints
may vary from a runny nose, sinusitis, earache or runny eyes
to itching of the skin, eczema and shortness of breath.
Conventional medicine can easily diagnose and treat allergies for foods or inhalants. Here, the so-called RAST test plays a very important role, because this test can demonstrate the presence of IgE.
However, demonstrating the presence of intolerance is more difficult. In this situation, similar to the case of classical allergies, the body responds abnormally and, in addition, the immune system does not produce IgE. It quite often takes much longer for complaints to come on, thereby masking the possible link between the offensive substance and the complaints themselves.
These are only a few of the reasons why food intolerance is considered a fairly controversial concept in conventional medicine. Intolerance can be responsible for a wide variety of complaints which, at first glance, seem to lack a plausible explanation. Intolerance can manifest themselves as the following:
It is impossible to accurately demonstrate intolerance through conventional testing methods.
The Amsterdam Clinic currently uses the following test, which is very reliable.
In the treatment of inhalant allergies (such as asthma, hay fever) and food allergies and intolerance, avoidance (elimination) of allergens plays an extremely important role. In the case of food sensitivities, either the cytotoxic test or IgG(4) test can help determine reactions to specific foods. Based on the test results, an elimination/rotation diet can be specifically tailored.
Foods causing strong reactions in these tests, should (temporarily) be excluded from the diet. More moderate reactions allow for rotation of certain food items in the diet. These may be eaten once every four days. Especially during the first week(s) of the diet, withdrawal symptoms, similar to complaints stemming from the cessation of coffee, tobacco or alcohol consumption, may occur. The body seems to crave offending food items. Generally, these withdrawal symptoms disappear after a couple of weeks. Concurrently, those complaints relating to food sensitivity also diminish.
Using this dietary approach, the reaction to food allergens may decrease in the course of time. After a three month moratorium, reintroduction of forbidden food items can be attempted, one at a time. In this way, food items still causing reactions can be isolated more easily. Often, at least part of existing intolerance completely disappear after an elimination/rotation diet.
With the treatment for inhalant allergies, elimination is also the first step. It is obvious that patients having an allergy for cats or dogs, should avoid any contact with these pets. The situation becomes more difficult when dealing with allergies to grass or tree pollen, since total elimination is basically impossible. The same goes for house dust mite allergy. The house dust mite lives in mattresses, pillows, carpeting, drapes, upholstery, etc. Through mite-killing pesticides, special mattress and pillow covers, non-carpeted floors, etc. reasonable results can be obtained.
Medicines for inhalant allergies, such as antihistamines (Triludan), corticosteroids (Prednisone, Pulmicort, Becotide), cromoglycates (Lomudal, Lomusol), and airway dilating medication (Ventolin, Berotec, Atrovent) do suppress symptoms, however, they do not cure the allergy! In the realm of conventional medicine, effective medications for food allergy and intolerance do not exist at all.
Enzyme-potentiated desensitisation (EPD) and the provocation/neutralization method are very effective treatments for food allergy/intolerance and inhalant allergy problems. These methods tackle allergy problems at the root.
