Food Intolerance Testing


Food intolerances affect around 45% of people and are implicated with chronic illness. There are a number of possible causes of food intolerance including enzyme deficiency, reactions to chemicals in foods, and the most difficult to resolve - delayed food allergies mediated by the IgG antibody.

Traditionally, elimination and challenge has been the first approach to identifying delayed food allergies.
Delayed food allergies often lead to chronic illness, and these reactions can occur from two hours to many days after ingestion of the offending foods, therefore making them difficult to identify.
Common chronic illnesses and conditions such as asthma, eczema, migraines, irritable bowel syndrome, arthritis and general continuous poor health have been associated symptoms of food intolerance.
Continuous consumption of the food to which you have an intolerance weakens your immune system. A weak immune system enables illnesses to develop and take hold. Many patients commonly report that they suffer from more than one illness at the time of taking the test.
Unlike classical allergies, usually more than one food is involved. We find that on average, sufferers react to four or five different and apparently innocuous foods.
Because of the delay between eating the food and the onset of symptoms, it is extremely difficult to identify the cause of the reaction without laboratory testing.
Food is intimately linked to your body's immune system. The immune system is the body's defence against foreign invaders, such as poisons and harmful bacteria. When you are sensitive to a food your body doesn't completely digest it, allowing incompletely digested food to enter the bloodstream where it is treated as an 'invader'. Therefore, if you are regularly eating foods to which you are intolerant, you are continually placing your immune system under stress.
This continual stress will eventually undermine and weaken the immune system, leaving you more susceptible to illness. By identifying the foods to which you are intolerant and eliminating them from your diet, you enable your immune system to do the job it was intended to do - protect you from illness.
Reactions produced by food intolerances are inflammatory and can be involved in a whole host of chronic health problems, some severe, some less so. The symptoms are often 'masked'; that is, they mimic the symptoms of common problems such as headache, fatigue and joint pains. Occasionally food intolerances will not produce the same reaction each time - one day they may show up as a headache, the next day as depression. The foods or substances which cause masked reactions are often the ones to which we are exposed to on a regular basis. In fact, you can even become addicted to the food causing the problem, so you then crave it and feel temporarily better for eating that food. As previously mentioned, the reactions are often delayed - therefore the sufferer doesn't associate the problem with the particular food causing it!

    There are a number of tests to determine food intolerances, mostly centering around the IgG test. This measures antibody reaction to a number of foods, in order to determine which specific foods may be causing adverse reactions.
