Food Intolerance

symptoms and testing

Do you suspect you have a food intolerance?

Research has shown that over 45% of us may suffer an adverse reaction to the foods we eat.


Unlike food allergies, food intolerances are not life threatening but can seriously impact our quality of work and home life, and may indicate underlying health problems. Symptoms commonly include abdominal pain, boating, constipation, skin problems, headache, low energy, weight gain, irritability, mental fatigue and poor memory.

Adverse reactions to food are not new but they do appear to be escalating, whether this is due to increased awareness, our stressful lifestyles or modern processed diets containing chemical-laden foods is still uncertain. What is certain is that undiagnosed food intolerances cause misery to millions of us, every single day. The solution sounds simple – identify and eliminate!

It can, however, be hard to identify problem foods as intolerance reactions are often delayed or there may be multiple reactions confusing the issue. Elimination diets can be effective means of identifying food intolerances but can take many weeks to complete and require a great deal of commitment. Food intolerance testing is a rapid and reliable means of identifying foods that may be causing an adverse immunological reaction. The test results provide clients with the motivation required to remove problem foods from their diets.

Eliminating foods from the diet can cause unhealthy nutritional deficiencies so our food intolerance tests include an advisory consultation at the nutrition clinic to  provide guidance on any necessary dietary changes. Food intolerances don’t usually come alone – there are often associated gut health issues to be addressed. At the clinic we will identify and address any associated or underlying health issues, and check for symptoms of food intolerance that are related to enzyme deficiencies.

  • Headache/migraine

Food Intolerance Testing


We offer a simple finger-prick test to identify foods which may be causing an adverse effect. The test is a rapid colorimetric ELISA (enzyme-linked immunosorbent assay) for the measurement of IgG antibodies to a selection of commonly eaten foods.

The finger prick sample can be taken at home and posted to the laboratory (Lorisian) for analysis; a full test kit and instructions are provided. A range of tests covering 75, 100 or 150+ popular foods and drinks are available – the 100 food panel is recommended. See here for information of the foods and drinks tested.

All food intolerance testing includes a 30 minute telephone consultation with BANT registered Nutritional Therapist, Wendy Urwin, to provide the advice and guidance you need implement any dietary changes with confidence and success.

Food intolerance testing is suitable for children over the age of 2 years. Please note that some food intolerances may be the result of non-IgG immunological reactions and may not show up on this test.
