Why Have a Food Intolerance Test

When addressing health and diet, food intolerance testing is a useful place to start as it can provide useful information when assessing the health of the digestive tract and immune system. It also highlights food that should be temporarily excluded or minimised. Food intolerance tests can help you to understand why you may experience digestive problems such as bloating, constipation and diarrhoea, cramping, flatulence and more. Food intolerance can be a contributing factor in conditions like IBS and inflammatory bowel disease and can also be the cause of seemingly unexplained symptoms. These might include fatigue, acne, and eczema, hives, acid reflux/ heartburn and indigestion, stuffy nose, catarrh, excessive ear wax and more.

Food intolerance test results need to be interpreted with care. In most cases you should not avoid the problematic foods forever. As part of your consultation we’ll show you how you can enjoy these foods in the future.

 

Food intolerance is usually a sign that there is an imbalance within your gut. Food intolerance doesn’t just suddenly appear; it is caused by something. During our consultation we’ll assess what this may be and discuss an action plan to correct suspected imbalances. Our goal is to help you avoid developing further intolerance and to heal any intolerance you may already have so that you can enjoy a varied diet.

 

What are the limitations of IgG tests?

  • Food intolerance tests measure your IgG immune reaction to foods because an IgG reaction is most commonly associated with food intolerance. It is not uncommon to have other types of immune reactions, for example IgE, IgM, and IgA. This intolerance test will not detect these types of immune reactions and therefore, may not detect every food intolerance you may have. It is possible to test these other types of immune responses, however it is costly. If you would like information on this more advanced testing please don’t hesitate to ask.

  • This test will not test for enzyme deficiency intolerance, such as lactose intolerance, as a different type of test is required for this.

  • This test will not test for food intolerance caused by gut bacterial imbalances (e.g. SIBO).

  • As this test is measuring the amount of antibodies in your blood to foods, it will not detect intolerance to foods that you have been avoiding for 3 months or more.

With these limitations in mind, this test is useful as a starting place. We insist on having the consultation alongside the intolerance test so that we can assess for these other types of intolerance, as well as other factors that may be contributing to your symptoms.

Technical Information

People can develop irritating and even life threatening TH2-driven IgE antibody responses to even the most minute exposure to the wrong dietary antigens. It is, however, important to note that only some of the people who are exposed to these substances make IgE antibodies against them. The first exposure may make people sensitive to the allergen without causing any symptoms. When these sensitized people subsequently encounter the allergen, IgE- expressing basophils and mast cells release substances (such as histamine, prostaglandins, and leukotrienes) that cause swelling or inflammation in the surrounding tissues. Such substances begin a cascade of reactions that continue to irritate and harm tissues. These reactions range from mild to severe.

The complement-negative IgG4 antibodies can combine with the specific food antigen to form a food immune complex. These complexes are thought to be the active agents for the delayed allergic responses. These complexes also have the potential to cause allergic food responses involving the anaphylactic response or sensitivity reactions. Such reactions can lead to a diverse variety of symptoms ranging from ill-defined malaise and fatigue to digestive disorders, skin problems, aching joints or back issues.

Blocking Potential: Data is available that provides support for the notion that a specific function of IgG4 in serum might also be to control antigen recognition by IgE and consequently, to regulate anaphylactic reactions and IgE-mediated immunity. Subsequently, studies have shown that the level of specific IgG4 was clearly lower than that of specific IgG1, suggesting that the major contribution of IgG4 in the competition effect is not due to higher levels but rather to a specificity spectrum close to that of the specific IgE. Moreover, these ‘‘blocking antibodies’’ have been demonstrated to have the potential to account for the clinical efficacy of immunotherapy for the neutralization of offending IgE species

Technical Information

IgG: Immunoglobulin G (IgG) is the main immunoglobulin circulating in human blood and helps protect us from infection and outside antigens. There are four subclasses: IgG1, IgG2, IgG3, and IgG4. IgG1 responds to new food antigens. IgG2 and IgG3 react to cell surface oligosaccharides of viruses, protozoa, and foods, which can be allergenic. IgG4 is commonly related to delayed food sensitivity symptoms. IgG can also activate the complement system to recruit an inflammatory response. The AIMS Food Sensitivity Profile measures total IgG (subclasses 1-4) antibodies for 88 foods.

Complement: Complement components patrol the blood harmlessly, but in an instant can go on the attack to kill and remove dangerous molecules from the body. When activated, the complement pathway sets off a domino effect of inflammatory cytokines, mast cell degranulation, and cell membrane destruction. It is a powerful protective force but can damage tissues if not kept under control. Complement is a quantifiable, reliable biomarker of tissue inflammation.

IgG4 + Blocking potential: A specific function of IgG4 in serum may be to control antigen recognition by IgE and consequently, to regulate anaphylactic reactions and IgE-mediated immunity. Subsequently, studies have shown that the level of specific IgG4 was clearly lower than that of specific IgG1, suggesting that the major contribution of IgG4 in the competition effect is not due to higher levels but rather to a specificity spectrum close to that of the specific IgE. Moreover, these ‘‘blocking antibodies’’ have been demonstrated to have the potential to account for the clinical efficacy of immunotherapy for the neutralization of offending IgE species.
