Food Intolerance & Special Diets
Finding Balance With Food
Food is meant to nourish and energise us — yet for many, certain foods can leave them feeling bloated, fatigued, or inflamed. When the body struggles to digest or tolerate specific foods, it can lead to a wide range of symptoms that often go unexplained.
​
As a Naturopath and Naturopathic Nutritional Therapist, I take a holistic and science-led approach to uncovering food sensitivities and supporting the body to restore balance.
Whether you’re living with a diagnosed condition such as Coeliac Disease or have noticed reactions to foods like gluten, dairy, or other common triggers, I’ll help you understand what’s happening — and ensure your diet remains both balanced and nourishing.
The goal isn’t to restrict — it’s to restore confidence, comfort, and enjoyment with food again.
Common Signs of Food Intolerance
-
Bloating, gas, or digestive discomfort
-
Constipation, diarrhoea, or erratic bowel movements
-
Fatigue, brain fog, or sluggishness after eating
-
Skin flare-ups such as acne, eczema, or rashes
-
Sinus congestion or headaches
-
Joint pain, inflammation, or stiffness
-
Low mood, irritability, or anxiety
-
Hormonal imbalance or menstrual changes
​
If you experience ongoing symptoms without clear answers, a food intolerance may be part of the picture.
Understanding the Food Intolerance
Food intolerance is often misunderstood. Unlike allergies, which trigger an immediate immune response, intolerances are usually delayed and can appear hours or even days after eating a trigger food. This makes it challenging to pinpoint the cause without professional support. While food intolerance testing can be a helpful tool, it’s important to understand that there’s no single test that determines whether your body is “happy” with a food or not. Understanding what you are testing for and interpreted carefully, always within the context of your symptoms, diet, gut health, and lifestyle. I help you understand why it’s showing that result, and what it means for your unique health picture. From there, we can work together to improve digestive resilience and gently reintroduce foods where possible.
​
It’s not only about removing foods forever - it’s about healing the underlying cause and rebuilding tolerance.
​
Supporting Special Diets
For some, supporting health may require removing or limiting certain foods - such as gluten, dairy, while for others, medical conditions like Coeliac Disease, IBS, or autoimmune conditions require more structured dietary approaches.
I can help you navigate these changes safely and confidently, ensuring your diet remains:
-
Balanced and nutritionally complete
-
Tailored to your individual needs
-
Supportive of gut and immune health
-
Practical and sustainable for everyday life
Whether you need guidance with a gluten-free or dairy-free diet, or you’re following a low-FODMAP, anti-inflammatory, or hormone-supportive plan, I’ll help you optimise your nutrition and maintain long-term wellbeing.
A well-balanced diet should heal, not hinder — even when foods need to be adjusted.

Functional Medicine Testing
Testing can provide deeper insight into your food reactions and digestive health. I offer flexible options depending on your goals and current needs:
-
Standalone Food Intolerance Test with Interpretation – Ideal if you’d like to test and get clear guidance on your test results. You can choose to add further support if required
-
Food Intolerance Testing as Part of a Package or Individual Consultation – Recommended for a more comprehensive approach, combining your results with a deeper understanding of gut health, inflammation, and nutrient balance.
​
Further testing may also be considered to provide a complete picture:
-
Comprehensive Stool Test – To assess digestion, inflammation, and microbiome balance.
-
SIBO Breath Test – To detect bacterial overgrowth contributing to bloating or intolerance.
-
FDX Functional Blood Work – To evaluate nutrient absorption, inflammation, and immune balance.
-
Nutrigenomics with LIFEcode GX – To explore how your genes influence digestion, detoxification, and inflammatory responses to food.
​
Functional medicine and nutrigenomic testing provide clarity - turning confusion into confident, evidence-led action for your health.
“I reached out to Claire after seeing another nutritionist who would not agree with me doing a food intolerance test. I had, what I felt, were typical symptoms of food intolerance, bloating, hives, itchy skin, aching joints and bloating. Claire listened to what I had to say and agreed to do the test in the first instance and see from there. The test came back with 4 foods in the red category and 3 in the amber, one of which was marked 100 - the highest score. Claire followed up the test with a zoom call and we went through what I needed to do next to help alleviate my symptoms. I know she will be at the end of an email if I run into difficulty or making no progress.
I have been nothing but impressed with my interactions with Claire. She has been sympathetic, knowledgeable and full of good advice.
I highly recommend her to anyone who is having problems that suspect may be related to food or diet in some way"
