Wheat is more than gluten — and it hides in more meals than you’d think. Get a personalised shortlist of wheat-related items worth exploring first, then run one focused 6-week elimination instead of months of guessing.
What this screen is — and what it is not
What it is
A shortlist to start from: your report flags wheat-related items worth exploring first, instead of leaving you to guess
A sensible launchpad for a focused 6-week elimination plan with structured reintroduction afterwards — the part that actually teaches you something
Helpful for deciding whether barley and rye are worth trialling separately
Non-invasive: just 9 or 10 strands of hair, with your report emailed within 3 days of your sample arriving at our UK lab
What it is not
Not a diagnosis of coeliac disease, wheat allergy, or any medical condition — if coeliac disease is on your mind, see your GP about blood tests while you’re still eating gluten
Not a measurement of your immune system, antibodies, ATI activity or gut inflammation — the items on the panel are screening categories, not biological readings
Not proof that wheat is behind your symptoms — only your own elimination-and-reintroduction trial can suggest that
Not an allergy test — rapid swelling, hives or breathing difficulty need urgent medical care, not a food screen
Why look at wheat beyond gluten?
Wheat contains several proteins. Gluten (gliadin and glutenin) is the famous one, but wheat also contains albumins, globulins and amylase/trypsin inhibitors (ATIs) — natural defence proteins researchers are studying for their possible role in how some people feel after wheat. Researchers use the term non-coeliac wheat sensitivity (NCWS) for people who feel unwell after wheat without the autoimmune picture of coeliac disease. The wheat-related items on your report are a screening shortlist — a sensible place to begin, not the answer itself. That’s exactly why the elimination-and-reintroduction trial is the hero here: you remove wheat for six weeks, keep a diary, then reintroduce it and watch what changes. Any difference you feel comes from that lived process — the report’s job is to make sure you start with the likeliest suspect instead of guessing your way through your whole cupboard.

How to run a focused elimination
Plan for a 6-week core elimination plan, then several optional weeks of careful reintroduction.
Week 1: Remove all wheat and wheat-containing products (bread, pasta, cereals, baked goods, sauces thickened with wheat starch). Read labels carefully. Swap in rice, corn, potatoes, oats (if they suit you) or gluten-free alternatives. Start your food diary on day one — the 90-day guarantee asks for at least 6 weeks on your plan with a diary.
Weeks 2–4: Keep wheat out completely and the diary honest: energy, digestion, skin and mood, a line or two a day. Many people notice shifts in bloating or brain fog around week 3–4, though everyone is different.
Weeks 5–6: Hold steady to the end of the core plan. Six consistent weeks is what separates a real pattern from a fluke fortnight.
After week 6 (optional reintroduction): Bring back one wheat product (a slice of ordinary bread, say) at breakfast and watch the next 48–72 hours. If it felt fine, gradually build portions and frequency back up. If symptoms returned, rest a week, then try a different form — pasta, or a slow-fermented sourdough, which tends to be lower in ATIs.
Afterwards: You’ll have a clearer picture of your own comfortable level with wheat. Some people settle on sourdough or the occasional serving; others prefer to keep it out. Your own trial — not the screening result — is what guides this.
Reintroduction works best done methodically: one food at a time, 48–72 hours of observation per item. If you bring wheat back and feel fine, you can move on to trialling something else (such as dairy or eggs) to sense-check whether wheat was ever really the issue, or whether several foods were interacting. If wheat does seem to unsettle you, there’s no need to panic — simply leave it out for another week, then try a different form (sourdough, an ancient grain, wholemeal, white) to get a feel for which type, if any, suits you less. None of this is a medical judgement; it’s a structured way of paying attention to your own body.
One customer’s experience
Priya had called herself ‘gluten sensitive’ for years because bread left her bloated — but she’d never tested the idea properly, just swapped loaves and hoped. Wheat came up on her IntoleranceLab report, so she gave it a real trial: a focused 6-week elimination with a food diary from day one. Over those weeks the bloating eased and she felt less sluggish, while the barley and rye still in her meals didn’t seem to bother her. When she reintroduced wheat afterwards, the heavy, bloated feeling came back within a day. Priya is the first to say it was the eliminate-and-reintroduce process — not the screening on its own — that gave her that clarity. The report simply gave her a sensible place to start. She now shops with more confidence, having worked out through her own structured trial which grain her body seems happier without.
Common questions
Is wheat intolerance the same as coeliac disease?
No. Coeliac disease is an autoimmune condition in which gluten prompts the immune system to harm the lining of the small intestine — it needs proper medical investigation, and our screening cannot rule it in or out. What people loosely call ‘wheat intolerance’ is broader: symptoms people notice after wheat, without that autoimmune damage (researchers call it non-coeliac wheat sensitivity). If you suspect coeliac disease, especially with a family history, ask your GP for the blood tests while you’re still eating gluten — cutting wheat out first can skew the results.
Can I react to wheat but feel fine with rye or barley?
Some people describe exactly that, and it’s a reasonable thing to explore. Your report lists wheat and gluten as separate items, so you can trial them one at a time — but the real sense of whether barley and rye suit you comes from everyday life: bring them back individually during your reintroduction phase and notice how you feel. If wheat seems to be the issue while rye and barley feel fine, that’s genuinely useful personal information, and it comes from your own trial.
Can I eat sourdough if wheat comes up on my panel?
Possibly — it’s worth trialling rather than assuming. Genuine slow sourdough fermentation (wild cultures over many hours) tends to reduce ATIs and partly break down gluten, which some people find makes a real difference. During your reintroduction phase, try a slice of a true slow-fermented loaf, watch how you feel over 48–72 hours, and compare it with ordinary bread. Bear in mind that mass-produced ‘sourdough’ made with commercial yeast isn’t the same thing.
What if wheat doesn’t come up but I still have symptoms?
That can happen, and it’s worth keeping an open mind. Your report covers 700+ items, but nothing can capture everything. If wheat isn’t flagged yet bread or pasta still seem to unsettle you, the culprit might be something else in those foods — yeast, additives, or other ingredients (some breads contain dairy, for example). If a wheat trial doesn’t help, or your symptoms are severe, persistent or worrying, see your GP — they can look into other explanations and refer you to a dietitian for tailored support.
Couldn’t any improvement just be expectation, or other changes I made at the same time?
The reintroduction step is built to answer exactly this. A pattern that survives reintroduction is hard to explain away: if your symptoms ease while wheat is out, return within a day or two of bringing it back, and ease again when you remove it, that tells you far more than one good fortnight. Yes, feeling better during any dietary change can owe something to expectation, lower stress, or simply eating more carefully — which is the whole point of changing one thing at a time, writing it down, and letting the diary, not your hopes, have the final say.
Do I need a dietitian to follow the elimination plan?
It’s helpful but not essential. Many people run the plan themselves: remove wheat, keep a simple diary, reintroduce one thing at a time. The main risk of going it alone is cutting out several foods at once, which can leave gaps in your diet and make it hard to tell which food matters — wheat contributes fibre, B vitamins and iron, so swap in alternatives rather than just removing. If you’re cutting out several foods or have other health needs, a registered dietitian is well worth it, and your GP can refer you.
When to speak to your GP. See your GP first if you suspect coeliac disease — especially with a family history, marked tiredness, unexplained weight loss or ongoing tummy pain. The blood tests only work while you’re still eating gluten, so don’t cut wheat out before you’ve spoken to them. If you ever have rapid swelling, hives or breathing difficulty after food, that needs urgent allergy care, not a food screen. If you’re removing a major food group for more than a few weeks, a registered dietitian can help you keep fibre, B vitamins and iron in your diet — your GP can refer you. And if symptoms persist or worsen despite your trial, go back to your GP to look into other causes.
