Food Intolerance Testing

Providing instantaneous results, this food intolerance testing method is simple, non-invasive and helps isolate potentially problem foods, drinks and additives. We test over 80 different substances. A vitamin and mineral analysis is included alongside basic nutritional counselling.

The food intolerance testing involves a bio-electronic analyzer which measures the body’s electrical resistance to individual foods. Problem substances affect the body’s electrical resistance and register in a lower reading. The test is completely painless. it is best described as a ball point pen touching the tip of your finger upon a acupuncture point.


You may benefit from food intolerance testing if you experience any of the following:

  • Low energy and fatigue
  • Bloating
  • Diarrhea / constipation
  • Food cravings
  • Heartburn / nausea
  • Headaches / migraines
  • Joint pain / swollen ankles
  • Respiratory symptoms (sinusitis, runny nose, asthma, itchy throat )
  • Skin complaints (Eczema, spots, hives)
  • Sinus / catarrh
  • Sleep problems

This test is suitable for all ages, including babies and children but it is not suitable for pregnant women or individuals fitted with a pacemaker.

Will I have to avoid certain foods forever?

This depends on whether you can tolerate the food once it has been reintroduced to your diet after a period of elimination. Your immune and digestive system may also need additional support to eradicate the underlying problem. In those instances, Charlotte can organise a more in-depth nutritional consultation.  

Cognitive Health Assessment

Charlotte Fraser integrates cognitive performance assessments in her nutrition consultations to measure how your brain is doing over time. Her nutritional therapy includes a quick, fun series of tasks that objectively measure your memory, reasoning, verbal ability, and attention—all facets of cognition that are important in your everyday life.


Why Measure Cognition?

There is an old saying that “if you can’t measure it, you can’t manage it,”and this applies to health and wellbeing too. We all have a subjective idea of how our brains are doing—some days we feel “off” or experience “brain fog,” while on other days we feel like we can take on the world. But how much better are we on the good days? And are lifestyle or health changes making a difference?

That’s where cognitive assessment comes in. By quantifying or putting a number to these subjective feelings, we can discover what is causing the good days in order to have more of them.

An engaging and scientifically-validated Cognitive Assessment Test

Charlotte Fraser Naturopathic Nutrition uses the CBS Health cognitive assessments developed by Cambridge Brain Sciences to measure brain health. We can assess, monitor, and manage core areas of cognition to ensure that your nutrition programme is on the right track. You complete the tests online remotely at home prior to your nutrition consultation.

The tasks assess aspects of cognition including reasoning, memory, attention and verbal ability.   


Is this an IQ Test?

NO! You can relax! We are not testing IQ! Think of it more like a blood pressure cuff for your brain. There’s no judgment, and the goal is progress over time, because we acknowledge that brain health changes from day to day. That’s why we believe we can improve or maintain your performance through improvements to both nutrition and lifestyle, and include cognitive assessments as a standard part of the programme.

Are cognitive assessments really relevant to me?!

Cognitive health affects almost every part of your life. Even conditions traditionally viewed seen as purely physical, such as pain or constipation, can effect cognition, and vice-versa. You’re not thinking well if you’re not feeling well.

What do results look like?

A sample CBS Health report is available here. The report is easy to read and understand. It becomes more valuable with each additional assessment, showing your progress and letting you know when meaningful changes occur. Charlotte Fraser reviews your report after each assessment in order to measure progress and make any adjustments to your health programme.

PHQ-9 Assessment for Depression


The PHQ-9 is a simple, 9-question instrument for screening, diagnosing, monitoring and measuring the severity of depression.  The assessment is online and takes 3 minutes to complete.

Endorsed by leading health organisations and the National Institute for Health and Care Excellence (NICE), PHQ-9 is one of the most used depression screens among Primary Care workers, clinicians and researchers.

Your PHQ-9 evaluation, together with the CBS Health Assessment gives you insight as to what is going on with both your cognitive and mental health.   These scientifically-validated assessments provide quantifiable evidence and further inform your personal nutrition and care programme.  

GAD-7 Assessment to Measure Anxiety Levels

The GAD-7 is a measure of general anxiety symptoms.

The combination of CBS cognitive tasks, the PHQ-9 and the GAD-7 make a powerful trio, which can be used as key outcome measures, mid-point check-ins to evaluate and customise your nutrition and wellness programme accordingly.
