Nut Intolerance
Experiencing bloating, fatigue, or skin issues after eating nuts? A nut intolerance blood test can detect immune reactions to proteins in common nuts.
Crack the Nut Mystery: Detect Delayed Reactions to Almonds, Peanuts, and More – Feel Lighter Daily
Snacking on trail mix or peanut butter, only to feel bloated, foggy, or achy later? Nut intolerance sparks subtle IgG immune responses to proteins in walnuts, hazelnuts, or cashews – fuelling gut discomfort, fatigue, or skin woes without allergy drama. Our blood test identifies these triggers, empowering dietary swaps for sustained energy and clarity.
A nurse draws a quick venous sample at home, results in 7 days – the insight to snack smarter and symptom-free.
The Delayed Nut Dilemma – How Everyday Snacks Silently Stir Up Discomfort
Nuts pack nutrition, but for the intolerant, their proteins provoke IgG antibodies, igniting low-grade inflammation hours or days post-bite – not the instant anaphylaxis of allergies. Post-almond handful: Bloating bloats your midsection, gas disrupts meetings, cramps cramp your stride, or nausea sours evenings. Deeper: Fatigue fogs focus, brain haze hampers productivity, irritability snaps at loved ones, headaches pound, or eczema itches anew – all chalked up to ‘busy life’ in nut-loving UK culture.
It’s exhausting trial-and-error – avoiding blindly starves omega benefits; testing spotlights culprits like peanut or walnut sensitivities, guiding precise eliminations.

Who Should Take the Nut Intolerance Blood Test? If Snacks Leave You Sluggish, Get Tested
This IgG screen targets hidden post-nut unease. Opt in if you’re:
- Hit with bloating, gas, cramps, nausea, or bowel shifts after nutty bites?
- Feeling fatigued, low-energy, or brain-fogged following snacks like granola or butters?
- Battling irritability, mood swings, or headaches tied to daily nut habits?
- Dealing with skin flares – acne, eczema, rashes – or even joint stiffness post-meals?
- A frequent nut consumer (e.g., vegan snacks, baking) with nagging digestive or mental dips?
Test once for foundational clarity; retest if symptoms return post-elimination or diet evolves.
What Your Nut Intolerance Blood Test Reveals – IgG Antibody Mapping for Nut Proteins
Our accredited UK lab assays your venous sample for immune signals, yielding a PDF report with rankings, symptom links, and avoidance tips. Primary marker:
- IgG as a Biomarker: Quantifies Immunoglobulin G antibodies to nut proteins (e.g., almonds, peanuts, walnuts, hazelnuts, cashews). Elevated IgG (above 20-50 units per nut) indicates delayed sensitivity fuelling inflammation; report scores each (low/moderate/high reaction) and correlates to symptoms like bloating or fatigue. Guides targeted trials, not standalone diagnosis.
Report features a nut sensitivity data and baseline for progress.
Ease Symptoms with Confidence – Personalised Steps from Your Results
Elevated IgG? Manageable – eliminate triggers for 4-6 weeks, often easing gut and mood in 70% of cases. Team with GP/dietitian:
- Elimination Phase: Cut specific nuts (e.g., swap peanut butter for sunflower); use apps like Fig for hidden sources in bars/chocolate.
- Reintroduction Trial: Re-add one (e.g., handful walnuts) after break – monitor for reactions; most tolerate alternatives like seeds.
- Nutrient Balance: Replace with sunflower seeds, chia for omegas; anti-inflammatories (ginger tea) soothe joints/skin. Probiotics aid digestion.
Negative? Positive – rule out nuts; probe other intolerances. Retest as needed for evolution.
What You Might Be Wondering – Honest Insights Inside
- Intolerance vs. allergy? IgG spots delayed (hours/days), not IgE’s acute threats – safe for non-severe cases.
- Recent eating needed? Yes – consume nuts 1-2x/week pre-test for detectable IgG; fasting not required.
- Home process easy? Quick, painless arm draw; private for food habit discussions.
- Guides or diagnoses? Informs elimination; GP confirms with history/symptoms.
Snack without second-guessing – test for freedom.

IgG as a Biomarker
IgG (Immunoglobulin G) is an antibody that signals your immune system has been exposed to certain foods. In food intolerance testing, raised IgG levels may suggest your body is reacting to those foods, potentially causing delayed symptoms like bloating, fatigue, or skin issues. While not a diagnosis on its own, IgG is a helpful marker for identifying possible food sensitivities when reviewed alongside your symptoms and dietary habits.
