If you experience uncomfortable or unpleasant symptoms after eating or drinking something, you may have an allergy, intolerance or sensitivity. This can make mealtimes difficult and frustrating, particularly if you’re not sure which foods your body struggles with.

To discover which foods you’re intolerant to, a food intolerance test can help you take back control of your health.

Why Check My Body Health Food Intolerance Tests

What is a food intolerance?

A food intolerance is when your body struggles to metabolise certain types of food, which can lead to uncomfortable and unpleasant symptoms such as bloating, sickness, vomiting and diarrhoea. A food intolerance can develop at any stage of your life, even if you’ve never experienced symptoms before. An intolerance tends to be lifelong, so if you suspect food could be the culprit, it’s recommended that you test for food intolerance so you can effectively manage it.


Did you know?
As many as 20% of the population experience some reactions to foods

Is there a difference between food intolerance and sensitivity?

A food intolerance is when your body can’t digest food properly, which is why many of the symptoms you experience are around the stomach and bowels. However, food sensitivity is similar to an allergy. The symptoms of a sensitivity are similar to that of an intolerance, but can also include headaches, skin rashes, breathing difficulties, fatigue and joint pain.

If you have a sensitivity or allergy, these can worsen over time. Severe allergies can also risk anaphylaxis.

bioresonance testing

Bioresonance testing

At Check My Body Health, we use bioresonance testing on all hair samples, which involves the use of electrodes connected to a Bicom machine, which measures the frequencies coming from your sample. If a frequency has a response over 84%, it’s considered an abnormality, and therefore you have an intolerance.

Because bioresonance testing is fast, affordable and scalable. That means, in just three days you can find out whether you have an intolerance to one or more of 970 items.
