Food sensitivity testing explained

On the back of the overwhelming response I received to my blog “Eczema: treat the cause, not the symptom” I thought it would be beneficial to explain the difference between allergy testing and food sensitivity/intolerance testing.

At Holistic Health Advice I recommend IgG blood testing, which covers 96 foods. The inflammatory response is given on a scale of 1 to 6. This scale is particularly helpful in understanding the severity of the reaction and in giving dietary advice.

IgG stands for Immunoglobulin (antibodies) subclass ‘G’. This is the class of antibodies which cause slower inflammatory reactions (particularly in the gut and lungs) as opposed to IgE ‘true’ allergic reactions.

To explain simply: we’ve all heard about those suffering from a peanut allergy who experience serious and life threatening anaphylactic reactions. This is IgE – instant inflammatory response. This is the type of test doctors generally offer.

Often those with eczema or asthma do not suffer ‘true’ allergic IgE intense and severe reactions. Rather, they have a slower inflammatory response that is difficult to link clearly with the ingestion of a specific food, due to the time lapsed between consuming the food and onset of a reaction.

IgG reactions are associated with ‘leaky gut’ / poor gut function where by the food particles pass through the gut wall and enter the blood stream. When these particles are recognised by the immune system, the body has an immune response to these invading ‘foreign bodies’. More and more antibodies are created to fight the perceived infection of the foreign food particles. IgG allergies can be treated by removing problem foods from the diet and by healing the gut with probiotics, digestive enzymes and fermented foods. Over time, the gut heals and then foods can be re-introduced without causing the previous reactions.

Can I get this test done with my G.P.?

Generally, the answer is ‘no’. Your doctor has access to this kind of testing, however they are not trained in this area of healthcare orĀ  choose not to use it. Medicare covers ‘true’ allergy testing, but to my knowledge, not sensitivity/intolerance testing. Despite growing evidence, the idea that IgG inflammatory response causes eczema, asthma and other health problems is generally unacknowledged and unrecognised by mainstream health professionals.

From my personal experience, when I approached my daughter’s dermatologist about the possible link between food intolerance and her eczema, I was told that I must be “getting desperate” if I was listening to and considering this line of treatment protocol – that is: looking to treat gut weakness and food intolerance as a solution to our daughter’s eczema.

If you feel that food intolerance may be an issue with you or your child’s eczema or asthma, I highly recommend you pursue this inclination.

Get to the root cause of what is causing ill health. Don’t be satisfied with treating the symptom with creams and steroids.
