Did you know that around 43% of people in the UK struggle with digestive discomfort? From bloating and constipation to diarrhoea and cramping, digestive problems are incredibly common (1). But here’s the tricky part: figuring out why your body is reacting can feel like a guessing game.

Many people suspect certain foods are causing issues, but identifying the culprits isn’t always straightforward. This is where understanding food intolerances comes in.

Food Allergies, Intolerances & Hypersensitivities: What’s the Difference? 🤔

You’ve probably heard these terms thrown around interchangeably. While they all involve an adverse reaction to a food, the underlying mechanisms differ:

• Food allergy (IgE-mediated): Immediate reaction (minutes to hours), and can be life-threatening (risk of anaphylaxis, hives, swelling of mouth, lips, difficulty breathing). It’s estimated that around 3% of the UK population have IgE-mediated food allergy and are at risk of potentially life-threatening allergic reactions (2).
• Food intolerance / IgG-mediated “food intolerance or sensitivity”: Delayed reaction, often appearing hours or even days after eating. Chronic low-grade inflammation is common as well as symptoms such as diarrhoea, IBS, eczema, headaches and chronic pain.

The takeaway? Not all reactions are obvious, and the same food can affect different people in different ways. Understanding the type of reaction is key to managing symptoms effectively.

Common Symptoms That Could Signal a Food Intolerance

Food intolerances often fly under the radar because symptoms are delayed or vague. Some signs include:

Digestive symptoms:

• Bloating, trapped wind, constipation, diarrhoea
• Irritable Bowel Syndrome (IBS), Crohn’s disease

Skin & inflammation:

• Eczema, psoriasis, neurodermatitis, breakouts

Other chronic complaints:

• Headaches or migraines
• Joint pain
• Thyroid issues
• Fatigue, restlessness, poor concentration
• Mood swings

Even “healthy” foods can sometimes trigger a delayed IgG response, leading to low-grade inflammation and contributing to these symptoms.

Why Gut Health Matters for Your Immune System 🌱

Over 70% of the immune system is located in the gut (3). When foods trigger delayed immune reactions, your body may be expending resources fighting “harmless” foods instead of real threats like bacteria or viruses. Identifying and managing these reactions may help to:

• Reduce unnecessary inflammatory processes
• Support digestion and nutrient absorption
• Free up your immune system to respond to real threats
• Improve overall energy and wellbeing

How ImuPro Helps You Understand Your Body 🧬

At AONM, we provide a bridge between complex science and everyday wellness with ImuPro—a blood test that measures IgG antibodies linked to delayed food reactions.

Here’s what makes ImuPro stand out:

• ✅ Tests up to 270 foods and additives, including common allergens (wheat, milk, eggs) and other triggers like Candida albicans and aspergillus niger (a mould found on stored grains).
• ✅ Detects IgG 1–4 antibodies, offering a more complete picture than many tests that only look at IgG4.
• ✅ Uses organic food proteins, reducing the risk of cross-reactivity from pesticides or herbicides.
• ✅ Provides personalised nutritional guidance and optional recipe books tailored to your results.
• ✅ Simple & convenient: a small blood sample can be taken at home or by a therapist, then sent to the lab for analysis.

With these results, you can identify your “trigger foods” and make informed dietary adjustments to reduce inflammation and support overall gut health.

Your ImuPro Options 🧪

ImuPro combines a reliable laboratory test identifying increased food-specific IgG antibody levels with personal guidelines for dietary changes based on the result. Depending on your needs, there are different levels of testing available:

• ImuPro Screen – Tests 22 foods. A simple and affordable first step to check whether IgG food reactions might be present. This option provides an analysis of potential food triggers but does not include nutritional recommendations.
• ImuPro Basic – Tests 90 of the most common foods. Includes a clear report plus personal nutritional guidelines with individual recommendations for your ImuPro diet.
• ImuPro Complete – Tests 270 foods and additives (including the 90 foods in ImuPro Basic). This option provides a detailed report, personalised nutritional guidelines, and a recipe book tailored to your results.

Who Can Benefit from IgG Food Testing?

• Individuals with chronic digestive complaints or inflammatory symptoms who are struggling to get relief or answers for their symptoms.
• People struggling with weight management despite a “healthy” diet.
• Practitioners looking for reliable, research-backed testing tools for patients.

ImuPro testing provides both patients and practitioners with clarity in an area that is often confusing and frustrating.
