Bloating. Digestive discomfort. Headaches. Skin problems. Fatigue.
When symptoms are affecting your quality of life, it’s entirely understandable to want answers. It’s also understandable that many people turn to food intolerance testing in the hope of identifying the foods that might be causing their symptoms.
In fact, one of the most common questions I hear is:
“Should I have a food intolerance test?”
Unfortunately, the answer isn’t always straightforward.
Why Food Intolerance Tests Are So Appealing
Food intolerance tests are widely available online and are often promoted as a way of identifying the foods responsible for symptoms.
Some involve finger-prick blood samples. Others use hair samples or bio-resonance technology. Many promise to provide a clear plan for what to remove from the diet.
For someone who has been struggling for months or years, this can sound incredibly appealing.
And I completely understand why.
People are not looking for restrictions.
They’re looking for relief.
Not All Tests Are Based on the Same Principles
One of the challenges is that food intolerance tests are based on a variety of different methods and technologies, and some have much stronger scientific support than others.
This means that two different tests performed on the same person may produce very different results.
That can leave people feeling confused and uncertain about what to believe.
What I See In Practice
As a Nutritional Therapist, I regularly meet people who have already undergone food intolerance testing before seeking professional support.
Often, they arrive with lengthy lists of foods they have been advised to avoid.
Sometimes the list contains 10 foods.
Sometimes 20.
Occasionally even more.
What concerns me most is that the report itself can become the focus, rather than the person.
The goal quietly shifts from:
“Why am I experiencing these symptoms?”
to:
“How do I eliminate every food on this report?”
Or from:
“How can I improve my digestive health?”
to:
“How do I make this test result normal?”
But numbers and reports are only useful if they help us move towards the real goal:
Feeling better.
Test results are pieces of information, not goals in themselves.
Good testing should help guide decision-making and support the next step, but it should never replace the bigger picture: the person sitting in front of us.
More Restriction Isn’t Always Better
I’ve worked with people who have:
- Removed large numbers of foods from their diet
- Become anxious about eating
- Spent considerable amounts on supplements
- Pursued repeated rounds of testing
- Become increasingly confused about what they can and cannot eat
And despite all of this effort, their symptoms have often remained unchanged.
In some cases, the dietary restrictions themselves have created additional stress and reduced the variety of foods in the diet.
The aim should never be to create the smallest possible diet.
The aim is to build the widest and most nourishing diet that your body can comfortably tolerate.
Food Reactions Are Real
None of this means that symptoms are “all in your head” or that food reactions aren’t real.
People absolutely can react to foods.
However, the reasons behind these reactions can be complex.
Digestive symptoms may be influenced by:
- IBS
- Coeliac disease
- Lactose intolerance
- FODMAP sensitivity
- Histamine intolerance
- Stress and the gut-brain connection
- Changes in the gut microbiome
- Bile acid issues
- Other underlying health conditions
Understanding the “why” is often far more valuable than simply producing a list of foods to avoid.
Asking Better Questions
Instead of asking:
“Which foods should I remove?”
A better question might be:
“Why am I reacting to foods in the first place?”
That shift in thinking often leads to more meaningful and sustainable solutions.
Testing Should Support the Journey, Not Become the Destination
One of the reasons I feel so strongly about this topic is that I regularly see people who have spent significant amounts of money on testing, only to be left more confused, more restricted and no closer to understanding their symptoms.
My concern isn’t that people are seeking answers.
Quite the opposite.
I understand why they do.
My concern is that, all too often, people invest in testing before they have had the opportunity to ask whether the test is actually likely to answer the question they are trying to answer.
Good testing can raise further questions and help guide the next step. It can provide valuable information and, when used appropriately, can be an extremely useful tool.
But testing should support the journey, not become the destination.
Ultimately, the goal isn’t to create perfect numbers or the smallest possible diet.
The goal is to help people feel better.
My role is not simply to help people interpret test results, but to ensure that the person never gets lost behind the printout.
Need Help Deciding?
If you’re considering a food intolerance test and would like independent advice before investing your money, my Independent Testing Guidance Consultation can help.
Together, we can discuss:
- Your symptoms and health goals
- The tests you are considering
- The potential benefits and limitations
- Whether testing is likely to provide useful information
- Alternative approaches that may be more appropriate
Sometimes the right answer is testing.
And sometimes the right answer is something else entirely.
Either way, my aim is to help you make informed decisions and avoid unnecessary expense, confusion and restrictive diets.
