This site is excellent for people that have Celiac Disease or DH. I took an article from the website: http://www.celiac.com/ The website has a list of gluten free foods and what is not, recipes, alot of important info, a blog for suffers. Allergy and Intolerance by Lydia S. Boeken M.D. By Published 7/26/1996 Allergy vs. Intolerance - What is the Difference? Rating: Unrated 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 and living happy, healthy gluten-free lives. Celiac.com was the first site on the Internet dedicated solely to celiac disease, and since then it has become an invaluable resource to people worldwide who seek information about celiac disease and the gluten-free diet. In 1998 I created The Gluten-Free Mall, Your Special Diet Superstore! which was also another Internet first—it was the first gluten-free food site to offer a shopping cart-style interface, and the

ability for people to order gluten-free products manufactured by many different companies at a single Web site.View all articles by Allergy and Intolerance by Lydia S. Boeken M.D. Introduction 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: An allergen must be present in the body. This allergen is the substance which causes us to have an abnormal immunological response. Allergens tend to be protein molecules. Interestingly enough, the immune system only detects particles of a certain size as potential troublemakers and protein molecules are just the right size. In a small number of cases, the body actually responds to molecules other than proteins. These molecules, which are generally much smaller, are called haptens. By combining with protein molecules, haptens form larger complexes which can then be detected by the immune system. The allergen is detected by the B cells. These are specialized immune cells, capable of producing antibodies. Just like allergens, antibodies are protein molecules, which have the capacity to neutralize allergens. Every B cell produces its own, specific antibody, depending on the type of intruder it needs to respond to. It is easy to understand why the body must have a ready pool of millions of

antibodies, in order to combat these numerous offenders. There are five main categories of antibodies (IgG, IgA, IgM, IgD and IgE) which the body releases under different circumstances (for instance to fight off various infections, etc.). In the case of allergies, the body produces the antibody immunoglobulin E (IgE), first discovered by the Ishizakas. Usually, antibodies will bind directly to the appropriate damaging substance and neutralize it. However, IgE deviates from this common path. It first attaches one of its legs to one of the bodys numerous mast cells. The other leg is used to hold on to the offending allergen. This action signals the mast cells to begin disintegrating, thereby releasing histamine. 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. Allergic 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. Intolerance 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: gastrointestinal complaints: stomach ache, irritable bowel, Crohns disease, ulcerative colitis Skin complaints: itching, eczema, hives, acne (in adults) Joint and muscle complaints: ranging from atypical pains to rheumatoid arthritis Headache and migraine Chronic fatigue Asthma, chronic rhinitis or sinusitis Pre-menstrual syndrome Hypoglycemia Depression, anxiety Sleeping disorders Diagnosing Intolerance

It is impossible to accurately demonstrate intolerance through conventional testing methods. The Amsterdam Clinic currently uses the following test, which is very reliable. Another useful test is the IgG(4) antibody test. Here, the presence of IgG(4) antibodies is determined. These antibodies are the slowly occurring variety, which do not appear in the blood until 24 to 48 hours after exposure to an offending food or substance. The reliability of this test varies between 80 and 90%. Treatment Diet 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. Medication 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. Desensitisation 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. During EPD treatment, a small quantity of a food or inhalant allergen mixture is injected intradermally into the skin, in conjunction with the enzyme beta-glucuronidase. This combination causes the body to gradually adjust its exaggerated responses to food and inhalant

allergens. In this way, the immune system is readjusted and reset. Initially, the injections have to be given once every two months. Gradually, however, the intervals between injections become longer and the injections can often be discontinued after a time. According to conservative estimates, at least 80% of those patients treated with EPD show considerable improvement in the course of time. Provocation/neutralization can be used both diagnostically and therapeutically. Here, separate extracts of food or inhalants, suspected as possibly offending, are injected intradermally. This causes a welt to appear in the skin. After 10 minutes, the size and nature (firmness, color, etc.) of the welt are evaluated. A positive welt will generally bring on symptoms (provocation). Depending on the size and nature of the welt, as well as, the presence of symptoms, varying concentrations are injected, until a dose is found which does not cause any welt changes or symptoms. This is

the neutralizing dose. Injections with the proper neutralizing dose will bring on immediate protection against the symptoms caused by the offending food and/or inhalant.
