Food Sensitivity Testing

Your Gut Map DX Food Sensitivity Map 270+ with Professional Nutritional Guidance

Comprehensive Food Sensitivity Testing with Professional Practitioner Support

Do you experience bloating, digestive discomfort, IBS, headaches, fatigue, skin concerns or other persistent symptoms that you suspect may be linked to the foods you eat?

At Charlotte Fraser Naturopathic Nutrition, we understand how frustrating it can be to live with persistent or complex symptoms when you are struggling to identify what may be contributing to them. That’s why we offer the YourGutMap DX Food Sensitivity Map 270+, one of the UK’s most comprehensive food-specific IgG tests, supported by professional practitioner guidance.

Whether your goal is to improve digestive health, support healthy skin, increase energy levels, optimise recovery, enhance sports performance or gain a better understanding of how your body responds to different foods, we are here to support you throughout your testing journey.

What’s Included?

Every YourGutMap DX FoodSensitivityMap 270+ purchased through Charlotte Fraser Naturopathic Nutrition includes a 45-minute practitioner-led results interpretation appointment.

During this appointment, we will:

  • Explain your laboratory report in clear, straightforward language.
  • Discuss your food-specific IgG reactivity results.
  • Help you understand how the findings may relate to your symptoms and health goals.
  • Provide guidance on implementing a practical elimination and reintroduction programme, where appropriate.
  • Answer your questions and help you feel confident about your next steps.

For many clients, this appointment provides all the support they need to understand and use their results effectively.

However, if you have complex, long-standing or multiple health concerns, we may recommend a separate comprehensive nutritional consultation. This allows us to explore your medical history, current symptoms, digestive health, medications, lifestyle and nutritional status in greater depth before developing a fully personalised nutrition and lifestyle plan.

If an additional consultation is recommended, this will always be discussed with you beforehand and booked separately.

What is a Food Sensitivity?

A food sensitivity *, sometimes referred to as a food intolerance, describes an adverse reaction to certain foods that may contribute to ongoing symptoms in some individuals.

Unlike a food allergy, which usually causes an immediate immune response and can be life-threatening, food sensitivities are often associated with delayed symptoms that may develop several hours, or even days, after eating. This can make identifying potential trigger foods particularly challenging.

Food-specific IgG testing measures Immunoglobulin G (IgG) antibodies that your immune system produces after exposure to foods. Whilst the results do not diagnose a food intolerance on their own, we interpret them alongside your symptoms, medical history and dietary intake to provide valuable information that helps guide your nutritional recommendations.

At Charlotte Fraser Naturopathic Nutrition, we never rely on laboratory results in isolation. We consider your symptoms, digestive health, lifestyle, nutritional status and personal health goals to build a complete picture of your health and develop recommendations that are appropriate for you.

Current research suggests that several factors may influence how individuals respond to different foods. These may include gut microbiome balance, intestinal barrier function, dietary diversity, genetics, stress and environmental influences. This is why we take a personalised approach, recognising that every individual is unique.

Could Food Sensitivities Be Affecting You?

Food sensitivities may contribute to a wide variety of symptoms. Although these symptoms can have many possible causes, identifying potential dietary triggers may provide valuable information when considered alongside a comprehensive nutritional assessment.

Symptoms Commonly Associated With Food Sensitivities Include:

  • Bloating
  • Excess wind (gas)
  • Diarrhoea
  • Constipation
  • Irritable Bowel Syndrome (IBS) *
  • Abdominal discomfort
  • Headaches and migraines
  • Fatigue and low energy
  • Brain fog
  • Eczema
  • Skin rashes
  • Acne
  • Hives
  • Joint discomfort
  • Respiratory symptoms

Why Do Food Sensitivities Develop?

There is no single cause of food sensitivities. Research suggests that a combination of factors may influence how the body responds to certain foods.

These may include:

  • Gut microbiome imbalances
  • Changes in intestinal barrier function (sometimes referred to as “leaky gut”)
  • Reduced dietary diversity
  • Low fibre intake
  • Food processing methods
  • Previous antibiotic use
  • Genetics
  • Chronic stress
  • Environmental influences

At Charlotte Fraser Naturopathic Nutrition, we recognise that every individual’s health journey is different. Rather than focusing on a single cause, we consider the wider picture to help identify patterns and develop practical nutritional strategies that support your overall wellbeing.

Breaking The Vicious Cycle

If you have been struggling with ongoing digestive symptoms, you may already have tried numerous approaches to find relief. This might include elimination diets, low FODMAP diets, supplements, medications or simply avoiding more and more foods in the hope of identifying the cause.

Whilst these approaches can be appropriate in certain circumstances, they do not always provide lasting answers. Over time, increasingly restrictive diets can become frustrating, confusing and, in some cases, may reduce dietary diversity. This can make it more difficult to achieve adequate nutrient intake and may have an adverse effect on the diversity of the gut microbiome.

At Charlotte Fraser Naturopathic Nutrition, we believe food sensitivity testing should help reduce unnecessary guesswork, not increase unnecessary restriction.

When interpreted alongside your symptoms, health history and nutritional assessment, the Food Sensitivity Map 270+ can help guide a structured elimination and reintroduction programme that is tailored to your individual needs.

Our aim is not simply to identify foods to avoid. It is to help you understand your body’s responses, restore confidence in food and build a balanced, varied and sustainable way of eating that supports your long-term health, gut health and overall wellbeing.

A Typical Journey Before Food Sensitivity Testing

What is the Research around Food Sensitivity?

Food sensitivities differ from food allergies. Whilst a food allergy usually triggers an immediate immune response and can be life-threatening, food sensitivities are often associated with delayed symptoms that may develop between 24 and 72 hours after eating. This delay can make it difficult to identify potential trigger foods through symptoms alone.

It is estimated that nearly 45% of the UK population experience adverse reactions to foods.*** For many people, identifying which foods may be contributing to symptoms can be challenging without a structured approach.

At Charlotte Fraser Naturopathic Nutrition, we use food sensitivity testing as one part of a comprehensive nutritional assessment. The results are never interpreted in isolation but are considered alongside your symptoms, medical history, dietary intake and lifestyle to develop personalised nutritional recommendations.

Published research has investigated the use of practitioner-guided elimination diets based on food-specific IgG testing. Whilst further research continues, several studies have reported improvements in symptoms following personalised dietary interventions.

In one published study, participants following an IgG-guided elimination programme reported improvements in the following areas****:

  • 82% improvement in bloating
  • 80% improvement in digestive health
  • 72% improvement in lung function
  • 78% improvement in neurological conditions
  • 76% improvement in skin conditions
  • 64% improvement in joint issues
  • 81% improvement in mental wellbeing

Whilst individual results will vary, these findings highlight the potential value of food-specific IgG testing when used alongside professional nutritional guidance and a personalised elimination and reintroduction programme.

Can Removing My Food Sensitivities Improve My Sports Performance Or
Fitness?*****

At Charlotte Fraser Naturopathic Nutrition, we work with a wide range of clients, including active individuals, fitness enthusiasts, competitive athletes, elite performers and people who simply want to optimise their health and performance through nutrition.

Optimising nutrition plays an important role in supporting digestive health, recovery, energy levels and physical performance. When the body responds to foods that may not be well tolerated, some individuals experience ongoing digestive symptoms or other health concerns that can affect comfort, confidence, training and recovery.

Identifying potential dietary triggers may therefore help support a more personalised nutrition strategy as part of a wider health and performance programme.

Researchers have also explored the role of food-specific IgG-guided elimination diets in sport. In one published study involving an elite football team, athletes who followed a practitioner-guided elimination programme reported the following improvements after 12 weeks*****:

  • Improved cardiovascular efficiency
  • 50% increase in distance covered on the field
  • 25% increase in calories expended
  • 18% increase in the number of accelerations
  • 7% increase in maximum speed
  • Reduced Rate of Perceived Exertion (RPE)

Whilst further research is needed and individual results will vary, these findings highlight the potential role that personalised nutrition may play as part of a wider health and performance programme.
