People who experience some of the symptoms of food intolerance are often led by the medical profession and the media to believe that their condition is ‘all in the mind’ and are treated for the physical manifestation of the condition rather than the cause. However there are now answers to your questions and ways to identify the cause of your symptoms leading to long term relief.
Although not life threatening like food allergy, food intolerance should never be underestimated as its impact on sufferers can be significant, severely impacting on their ability to live normal healthy lives. Food intolerance is extremely widespread and it is estimated that 45% of the population could be affected.
Many people with food intolerance experience more than one symptom. Symptoms can often be vague and the root cause of the problem, food, is not always correctly diagnosed. Sufferers often complain of seeming to be in a ‘fog’, feeling bloated and being tired all the time.
But the two are frequently confused.
A classical food allergy (such as peanut or shellfish allergy) is usually characterised by an immediate and often severe reaction of the immune system to exposure to a specific food.
The symptoms of food allergy include sneezing, rashes, skin irritation, swelling, runny nose, fatigue, diarrhoea and vomiting. Normally symptoms occur within a few minutes of eating or coming in to contact with the offending food, although they can be delayed by up to two hours. Food allergy is quite rare with only about 2.5% of the population being diagnosed with the condition. The most common instances of food allergy are to peanuts, tree nuts (almonds and brazils), eggs, milk, fish and shellfish.
When exposed to the source of food allergy the body makes specific antibodies (IgE) to ‘fight off’ the allergens found in these foods. When the food is next eaten it triggers an immune system response which results in the release of histamine and other naturally occurring chemicals in the body. Allergic reactions to food can vary considerably in their severity and some can be fatal.
Genarrayt® is a laboratory-based system developed and manufactured by Genesis Diagnostics Ltd, which utilises an innovative, colorimetric microarray-based ELISA technology for the measurement of food-specific IgG antibodies in human serum, plasma or whole blood. The flexibility of the system permits a wide range of food panels to be offered, including 40, 60, 120 and 200+ foods, together with vegan, vegetarian and herbs/spices options.
