Food Intolerance Testing

A food intolerance is the term used to describe a wide range of symptoms that occur because of the body's abnormal reaction to certain foods. This is not the same as a food allergy. Food allergies involve the immune system, whereas food intolerances involve the digestive system. A food allergy test will not show up a food intolerance and vice versa as different antibodies are involved. 

 

Some symptoms of a food intolerance include headache and migraine, IBS, bloating, brain fog, fatigue, stomach pain, diarrhoea, recurrent mouth ulcers, rashes, hives etc (see below).  Many people with a food intolerance experience more than one symptom, having a food intolerance is often described as being in a 'fog' and feeling tired all the time.  For some people it is the accumulation of eating certain foods that eventually tip them over the edge and this is when they start to show symptoms, in these cases the intolerance can be quite vague, sometimes taking days to occur. 

Some of the common food intolerances seen in clinic include

 

- Lactose intolerance, where there is a deficiency in the enzyme necessary to break down sugars in milk. 

- Carbohydrate malabsorption, including the sugars found in FODMAPS such as fructose and polyols.

- Sensitivity to natural chemicals found in foods such as amines, glutamates and salicylates.

- Sensitivity to added chemicals and preservatives

The testing tray that shows if the person has IgG antibodies to specific foods has areas spotted with food protein extracts. A small blood sample is taken from a finger-prick and is then diluted and added to the tray,  results are available in just 40 minutes.
