The Food Intolerance Test

How is the food intolerance test carried out?

The food intolerance test is carried out with a Bio Resonance testing machine. This is a sophisticated electronic device which measures your response to a wide range of food and drinks. It is a non-invasive procedure which means that there are no needles involved.

To receive the test you simply hold a metal rod in one hand as the end of your finger is gently probed with a metal stylus, which looks a bit like a ball point pen.
"Further to my consultation with you in January I wanted to thank you for your help and advice. My symptoms have improved amazingly and I've never felt better. At our discussion, I told you changes to my diet normally only worked for a week or 2 max, hence I've left it so long to write to you. However, the advice you've given me is still working and I am hopeful this will continue in the longer term. Thanks again for all your help."

Is there anything I need to do before the test?

  • Please do not wear any perfume, cologne, aftreshave or body spray. A normal amont of deodorant is ok. 
  • Please remove your watch and all jewellery, including earings. If you have some piercings or rings that never come off that's fine. But anything that can be removed should be removed.
  • Please don't be chewing gum.
  • Please turn your phone fully off or on to flight-mode as the signal can affect the test results.
  • Please remove phones, keys and coins from your pockets.
  • Please remove all metal hair grips.
  • If you are wearing a belt the buckle shouldn't be in direct contact with your skin. 
  • Please eat and drink as you would normally.

How much does the food intolerance test cost?

  • The Basic Food Intolerance Test costs £70.

  • The Extensive Food Intolernace Test costs £85. ​
Both tests include a consultation. Payment can be made by cash or card.

  "I should say that the symptoms I had when I came to see you went almost immediately on changing my diet and I am feeling great."

Do I need to prepare for the consultation?

Not at all. I am very experienced at asking the right questions to get the informaion that I need in order to help you. However, as I shall be asking you what you eat and drink on a regular basis if you did want to keep a food and drinks diary for the week (or at least a few days) prior to the test that would be fine. Not a problem if you don't. However, of you do please include EVERY food and drink you consume. During the consultation I shall be asking you if you have ever had any operations, taken antibiotics or had any serious illnesses. I'll go through every system of the body and ask if you have, or have had, a tendancy towards any particular symptoms. I'll ask about any medication or contraception that you may be on. I won't necessarilly need to know the names, just what they are for. I like to make sure that there is plenty of time at the end of the consultation for me to give you the advice and recommendations that I believe will help you so concise, accurate answers are best. 

Do you include advice on nutrition and supplementation?

The test is very helpful at pin-pointing which foods are causing a problem. However, usually things are a little more complex. By looking at your health and diet in detail I can, as a Nutritional Therapist, offer you additional advice and recommendations which will help support the dietary changes that you will make.

Do you create a diet plan for me to follow?

My aim is to give you as much information as possible during the consultation so that when you leave not only do you feel inspired to make the necessary changes, you understand why you are going to do so, and the benefits you expect to achieve. During the consultation I may give you a few suggestions about what to eat but I won't be providing you with a diet plan. Everyone has their own specific test results, time constraints, tastes and lifestyle so it isn't possible to have a one-size fits all approach. However, the internet is a wonderful source of recipes and menu ideas so you will be able to put together your own plan in no time. 

How long does it take to get the results?

You'll receive the results of the Food Intolerance Test immediately together with recommendations for any dietary changes and vitamin and mineral supplementation that would be helpful to you.
"Now I know what foods to avoid to have the most energy.
I hadn't realised that I felt so tired because of what I was eating."

Is there anyone who can't take the test?

  • It is not recommended for anyone who has a pacemaker. 
  • I don't test women during pregnancy. 
  • Children 6 and over can be tested but they need to be able to sit fairly still during the test which takes about 15 to 30 minutes. This depends very much on the co-operation of the child. They need to be able to keep their hand still and flat and not mind me prodding the end of their finger with a stylus. Most children are fine with it but occasionally a child isn't able to sit and the test can't be carried out. 

What happens after taking the food intolerance test?

I usually recommend that you cut the highlighted foods out of your diet for 6 to 8 weeks to allow your body to become clear. If you do this suddenly you may get withdrawal symptoms such as headaches or cravings. Some people are fine with that but you may prefer to wean yourself of them graduallly over a couple of weeks before begining the elimination period. For some people a reduction in symptoms can happen almost immediately. However, if you are in any way constipated or are experiencig a skin issue that needs time to heal, or have inflammation, it can take time for your body to be clear of the offending irritants so at times an 8 week period of elimination is best. 

Once you have completed the elimination period begin to re-introduce the foods and drinks one at a time, leaving a gap of at least 3 days between each reintroduction. Pay close attention to any symptoms or reactions immediately after eating and over the next couple of days. This is the best way to get a clear picture of how those foods were affecting you.


I cut out tomatoes and oranges as the test suggested and noticed the dryness and redness on my face and chest disappearing within a week. A few weeks later I cut out cows milk out of my diet as per your suggestion and it helped my psoriasis on my scalp so much my boyfriend couldn't believe the difference. I now find I can actually eat any of the foods above and I am not affected, as long as I eat in moderation. My colleagues can't believe how good my skin is looking and my boss has booked for a test next month with you!
