Food intolerances are not the same as food allergies. The table below clearly outlines the difference;

Food Intolerance Food Allergy
Reactions can take place up to 72 hours after eating, making it difficult to pinpoint which foods are causing a problem A reaction takes place within 2 hours
Multiple foods can be involved, and any system can be affected Rarely more than one or two foods are involved. Primarily the airways, digestion and the skin are affected
Different amounts of trigger foods can be tolerated Trace amounts of foods can cause a reaction
Food intolerance can be difficult to self-diagnose Allergies are specifically caused by raised levels of IgE antibodies
Symptoms can clear after  a period of avoidance The condition is life-long


Although not life threatening, food intolerances can have a huge impact on your ability to live life to the full. This is because symptoms are chronic and can have a profound effect on your work and your social life. On the other hand, identifying which foods are causing problems can be challenging. This is because symptoms vary, and can appear anything up to 3 days after consuming a trigger food. Many common symptoms such as headaches, bloating, mood changes and fatigue can also be caused by other factors. This makes it hard to pinpoint where the real problem lies. Following an exclusion diet can be helpful, but as more than one food is often involved, the process can be lengthy and exasperating when all you want to do is gain relief from your symptoms. Food intolerance testing does away with the “trial and error” approach, and definitively identifies those foods that are causing you problems.

Empower yourself today & take back

your health


It’s currently estimated that around 45% of the population here in the UK have some form of food intolerance. Many experts believe that this surprising figure is linked to modern developments in food production, and the changing nature of our nutritional landscape.

Food today is very different to the food consumed just 40 years ago. Intensively farmed crops, highly processed packaged meals, industrialised cooking methods, additives, pesticides… our digestive systems have a hard job keeping up with these rapid changes in our diets. Not only has what we eat changed, but what we know about food is also evolving. Never before have we had so much access to information about nutrition. Despite this, there’s increasing confusion around what to eat, and the number of people with food related complaints continues to rise.

Irritable bowel syndrome, metabolic disorders, skin complaints and many other “difficult to get to the bottom of” conditions can be significantly helped by testing for food intolerances. It takes all the guesswork out of knowing which foods to eat and which to avoid, and provides you with the knowledge you need to regain your vitality and start living life to the full.


The food intolerance test can be done here at the clinic, or if you prefer, in the comfort of your own home. Once completed, samples are sent to Lorisian, a dedicated hospital standard laboratory who have over 30 years experience in the field of diagnostic testing. All testing and results are overseen by a medical doctor.

The test involves nothing more than a simple pinprick. It’s so quick and easy, it can be done anywhere, at any time. Once you have your sample, it’s simply a matter of sending it off to the lab. On average, it takes around 10 days for the results to come back.

Here’s how it works:

When foods and drinks are digested, the proteins within them are broken down into smaller fragments which are easier for the body to absorb. However, larger fragments can also pass through, and sometimes the body reacts by attacking them using antibodies called Immunoglobulin G’s (IgG). The food intolerance test analyses these IgG antibody reactions to give you a complete breakdown of all the foods which may be problematic for you.


Analyses your IgG antibody reactions to 75 common food ingredients

Analyses your IgG antibody reactions to 100 common food ingredients

Tests & analyses IgG antibody reactions to 150+ food & drink ingredients

The cost of the food intolerance testing service includes a 30 minute assessment to discuss your current issues, plus the laboratory test. Prices are as follows:

75 foods £145

100 foods £179 (A £30 customer refund applies should the results come back as negative.)

150 foods £250 – Please note that this test breaks down foods into subcategories (eg – individual grape species for those of us who enjoy the odd glass of wine!) therefore, the price reflects more than the number of individual foods tested.) In this case a £50 customer refund is offered should the results prove negative.

Follow up consultations to discuss results are priced at £25. This includes take away resources to support you in making any necessary dietary changes.

Free email support is also available during office hours for the duration of your time as a client at the clinic.


Further information about the specific foods tested can be found on the Lorisian website:

Information leaflets can also be sent out via post (please remember to include details of your postal address when you enquire.)
