Cereals containing gluten

Cereals containing gluten es la entrada 1 de las catorce sustancias que el anexo II del Reglamento (UE) n.º 1169/2011 hace declarables. Coeliac disease (autoimmune), wheat allergy (IgE) and non-coeliac wheat sensitivity — three different conditions under one entry. Dónde se esconde, qué exenciones aplican y con qué reacciona de forma cruzada.

Esto es información de referencia, no un diagnóstico ni un plan de tratamiento. Un calendario de polen no puede decirle a qué es alérgico, y ninguna página puede declarar un alimento seguro para usted — solo la etiqueta del paquete en la mano y el clínico que conoce su historia. Cualquier cosa más allá de síntomas leves y de corta duración en boca o nariz — hinchazón que afecta la respiración o la deglución, urticaria lejos de la boca, sibilancias, vómito o desmayo — es una pregunta de emergencia, no de lectura.

Qué dice la ley

Anexo II, entrada1: “Cereals containing gluten, namely wheat (such as spelt and khorasan wheat), rye, barley, oats or their hybridised strains, and products thereof”

Esa redacción lleva toda la obligación. La sustancia debe declararse siempre que se use en la elaboración de un alimento y siga presente en el producto acabado, incluso en forma alterada, y debe destacarse en la lista de ingredientes por tipografía — negrita, mayúsculas, cursiva, subrayado o un color contrastado. No hay requisito legal de un recuadro de alérgenos aparte, así que la lista de ingredientes es donde mirar.

Qué es realmente la reacción

This one entry covers conditions that have nothing in common except the grain. Coeliac disease is an autoimmune reaction to gluten that damages the small-intestinal lining and is diagnosed by serology and biopsy, on a gluten-containing diet — which is why you must not remove gluten before being tested. Wheat allergy is an IgE food allergy that can cause immediate hives, vomiting or anaphylaxis. Non-coeliac wheat sensitivity is a symptom-defined diagnosis of exclusion. The label rule is the same for all three; the medicine is not.

Who gets it, and does it last

Coeliac disease is lifelong and the treatment is a strict gluten-free diet under dietetic supervision, with follow-up. Childhood wheat allergy is often outgrown. A distinct and easily missed form is wheat-dependent exercise-induced anaphylaxis, in which wheat is tolerated normally but causes a systemic reaction when eaten before exercise; its marker is omega-5 gliadin.

Where it hides

• Soy sauce, which is usually brewed with wheat
• Stock cubes, gravy granules and sauce thickeners
• Sausages, meatballs and pâtés using rusk or breadcrumb
• Beer and malt vinegar
• Communion wafers
• Some sweets, liquorice and ice-cream cones
• Barley malt extract in breakfast cereals

This is the hardest allergen to live with in this region, because rye bread is the staple of the Estonian, Latvian, Lithuanian and Finnish table and barley runs through the traditional cooking of all of them. Oats are grown and eaten heavily here too, which makes the certified-oats question a practical daily one rather than an academic one.

Cross-reactions

Wheat, rye and barley proteins overlap enough that all three are excluded in coeliac disease. Oats are the argument: most people with coeliac disease tolerate pure oats, but ordinary oats are milled and transported with wheat, so only oats certified as gluten-free are used. Grass pollen allergy is not wheat allergy, despite the botanical relationship.

The labelling detail

The specific grain must be named in the ingredient list and emphasised there — bold, capitals, a different colour or underlining. Separately, "gluten-free" is a regulated claim: Commission Implementing Regulation (EU) No 828/2014 sets it at no more than 20 mg of gluten per kilogram, with "very low gluten" at no more than 100 mg/kg for specially processed cereal products.

Exempt from declaration under Annex II:

• Wheat-based glucose syrups including dextrose
• Wheat-based maltodextrins
• Glucose syrups based on barley
• Cereals used for making alcoholic distillates, including ethyl alcohol of agricultural origin

Precautionary wording — “may contain”, “made in a factory that also handles” — is a separate matter: it is voluntary, unstandardised and carries no threshold. How strictly to treat it is a clinical decision, not a reading of the label. The labelling explainer sets out the whole frame, including what happens in restaurants and bakeries where there is no pack at all.

Qué se lee mal

Going gluten-free before a coeliac test is the single most common and most expensive mistake: it can make the diagnosis impossible without a supervised gluten challenge months later. "Wheat-free" is also not "gluten-free" — spelt is wheat, and rye and barley are neither.
