The Gut and Skin Clinic



No. A food intolerance is not a medical condition. Nor does it require a diagnosis by a doctor. Unlike and allergy, a food intolerance is shown by undergoing a wellness test. At Dublin Vitality Centre, food intolerance testing is considered a non-diagnostic, “stress test” that aims to show foods that may be  stressed or imbalanced at any time. Knowing the foods which are imbalanced can assist a person who is planning to trial eliminate suspected food intolerances. If you are suffering from allergies, suspect you may be or wish to receive a diagnosis, please contact your GP.


Certain supplements can help your gut and digestion. For example, probiotics are useful when overcoming food intolerances. Digestive enzymes may also help to support your digestive system get the maximum benefit from the foods you eat during the 3 month period.


Your chart will be explained to you on the day of your food intolerance test at Dublin Vitality Centre. Reading it is simple. To help you understand and read your chart better, it is colour coded. Please consider the following explanations for each colour. However, the best approach would simply be to avoid all the “non-green” items that appear on your chart. All food groups appearing “non-green” should be trial eliminated from the diet for no more than 3 months and then introduced one by one monitoring the response on your body as you do so. If you notice a unpleasant response, perhaps removing this food for longer is a good idea. Always consult with your GP before making permanent changes to diet. 

Chronic – A chronically imbalanced food that is persistent or long-lasting .lt has developed over time. It may take time to recover ie the full 3 months in some cases.

Acute – Acute may be a more severe imbalanced to a food or that which has a sudden onset. It may have developed more recently.

Please note that you should treat all the food that appears non-green on your chart in the same manner.

That is, to trial eliminate or remove for up to 3 months, monitoring your body’s response as you re-introduce the food after that time.

Many foods appeared imbalanced on my chart. What should I do?

Optionally, you may start your trial elimination by removing the most imbalanced items as a priority  and watch to see if symptoms do improve. These will be the black and the red items on the chart.

What if a food appears twice on my test with a different result?

It is not unusual for suspected items to be tested twice at varying frequencies. In fact, the BioScan tests each item four times. Sometimes an item appears twice on the printed chart. If any item appears imbalanced at any testing frequency, it would be recommended to trial eliminate this food for the recommended period of up to three months to see if symptoms improve.

During the test, the clinician tested some items twice.

The BioScan is provided by a trained clinician who monitors the response during the test. If they wish to verify an item, they may test it twice. This is to ensure accuracy and consistency.

Many people report feeling better through natural wellbeing practices like removing imbalanced foods for three months. It may be helpful to keep a food diary as you undergo this trial elimination. Only avoid foods for up to three months. After that all foods should be  rebalanced, and are ready to be re-introduced. Please do ensure to ask your physician before making any long-term changes to your diet, and do not remove any food for more than three months, as  this should be long enough for an imbalance to clear up. 


Avoid alcohol. Take any medications as normal. Drink plenty of water. Get a good sleep the night before. Eat light food that morning. Do not fast. Please not, BioScan testing is not offered to those who are taking anti-histamines or steroids, or who have a pace-maker for epilepsy. Steroids, anti-histamines or other allergy meds may suppress the result of your test and make any imbalance undetectable.

Any food tested should be in your system. Naturally foods which you have not eaten in the past three months cannot be detected in the body. Therefore, if you have been avoiding a certain food and if you are not allergic to it, you might take a small sample in advance of your test if it is safe to do so.


A food intolerance is a temporary reaction to a certain food. If you have experienced gut health issues or skin conditions like spots, you may have a food intolerance. Allergies are not the same as food imbalances. Allergies are medical conditions that can cause anaphylasis, swelling of the lips and throat, and are therefore much more serious. If you have an allergy or suspect you have, you should not book the BioScan as it is a non-medical wellbeing test which can identify imbalances to suspected intolerances, but instead you should visit your doctor.


The Bioscan food test does not diagnose food intolerances or any other condition but in fact identifies foods which you may currently be imbalanced to. A trial elimination period of no more than three months is recommended on any food that shows up as imbalanced. Always check with your GP before making dietary changes. If you are seeking a diagnosis of any type, please visit your doctor.
