Gluten-Free Meal Plan: 7-Day Menu and Safe Shopping Tips

Quick answer

Build meals on naturally gluten-free foods; get tested before cutting gluten

Gluten is a protein in wheat, barley and rye (and oats, unless certified gluten-free, because of contamination). Naturally gluten-free foods include vegetables, fruit, meat, fish, eggs, dairy, legumes, nuts, rice, maize, quinoa, buckwheat, millet and potatoes. Hidden gluten occurs in sauces, soups, gravies, processed meats, soy sauce, beer and many ready meals; check labels, which must declare wheat, barley and rye. Cross-contamination from toasters, shared utensils or fryers matters for coeliac disease. See a doctor for testing before starting a gluten-free diet, because tests need gluten in your diet to be reliable and a gluten-free diet without need is not healthier.

Important. Do not start a gluten-free diet before being tested for coeliac disease if you suspect it. Chronic diarrhoea, weight loss, anaemia, severe fatigue, mouth ulcers, a blistering itchy rash or growth problems in children need medical assessment.

Who needs a gluten-free diet?

Coeliac disease: an autoimmune reaction to gluten damaging the small intestine; strict lifelong gluten-free diet is the treatment.
Dermatitis herpetiformis: an itchy blistering skin condition linked to coeliac disease.
Wheat allergy: avoid wheat; barley and rye may be fine.
Non-coeliac gluten sensitivity: symptoms on gluten without coeliac disease or wheat allergy; diagnosis is by exclusion.
There is no proof that a gluten-free diet is healthier for people without these conditions, and gluten-free processed foods can be higher in sugar and fat and lower in fibre. See arroz y gluten (Spanish) and foods high in fibre.

Get tested before you cut gluten

Blood tests for coeliac disease (tissue transglutaminase antibodies, with total IgA) work only if you are eating gluten, usually at least one slice of bread (or equivalent) in more than one meal daily for 6 weeks. Starting a gluten-free diet first can give a false negative and delay diagnosis. Diagnosis is confirmed by a clinician, sometimes with a biopsy of the small intestine, and relatives of people with coeliac disease are at higher risk.

Naturally gluten-free foods

Fruit and vegetables: all fresh, frozen and plain canned.
Protein: fresh meat, poultry, fish, eggs, tofu, plain nuts and seeds.
Dairy: milk, plain yoghurt, cheese (check flavoured and processed).
Legumes: beans, lentils, chickpeas.
Grains and starches: rice, maize (corn), polenta, quinoa, buckwheat, millet, amaranth, teff, potatoes, sweet potatoes, tapioca.
Fats: olive oil, butter, avocado.
Others: herbs, spices (pure), honey, wine and spirits, cider.
Certified gluten-free oats are tolerated by most coeliacs, though a few react; ask your clinician.

Foods that contain gluten

Wheat in all forms: bread, pasta, couscous, semolina, spelt, kamut, farro, bulgur, seitan.
Barley (including malt) and rye.
Beer and malt drinks (unless labelled gluten-free).
Baked goods, biscuits, pizza, pastries, pancakes, batter and breadcrumbs.
Many sauces, gravies, stock cubes, soy sauce, salad dressings and soups.
Processed meats, sausages, meat substitutes and some ready meals.
Many cereals, granola bars and snack products.
Some medicines and supplements; ask your pharmacist.

Reading labels and “hidden gluten”

In the EU and UK, wheat, rye, barley and oats must be highlighted in the ingredients list; in the US, wheat is an allergen but barley and rye may not be flagged, so check for “gluten-free” labelling.
“Gluten-free” means under 20 parts per million of gluten in the US, EU and UK.
“May contain” statements indicate cross-contact risk; clinicians vary in advice.
Watch for malt, brewer’s yeast, modified food starch from unspecified sources, and hydrolysed vegetable protein.
Sauces, soups, spice mixes, processed meats, ice cream and chocolate can carry gluten.
Re-check labels because recipes change.
Certified products from coeliac associations are reliable.

Avoiding cross-contamination at home

Use a separate toaster or toaster bags, and separate butter, jam and spread jars.
Clean surfaces, boards and utensils thoroughly; use separate colanders and wooden spoons.
Cook gluten-free pasta in fresh water.
Avoid shared fryers and grills.
Store gluten-free foods on higher shelves to avoid crumbs.
At restaurants, inform staff about coeliac disease and ask about preparation.
Travel with safe snacks.

Making a gluten-free diet nutritionally complete

Gluten-free substitutes often have less fibre, iron, B vitamins, folate and calcium than their wheat counterparts, so rely on naturally gluten-free whole foods: legumes, vegetables, fruit, whole gluten-free grains such as quinoa, buckwheat and brown rice, nuts and seeds, and fortified products where available. People with newly diagnosed coeliac disease may need iron, vitamin D, B12, folate, calcium or other supplements, guided by blood tests and a dietitian. Follow-up includes antibody levels and bone health assessment.

When to seek advice

Chronic diarrhoea, bloating, weight loss, anaemia or fatigue.
A first-degree relative with coeliac disease.
Type 1 diabetes, autoimmune thyroid disease or Down syndrome, which carry higher coeliac risk.
Symptoms persisting on a gluten-free diet: ask about hidden gluten and other conditions.
Children with poor growth or delayed puberty.
Before starting any elimination diet.

Three common situations

Someone with bloating who plans to cut gluten: get tested first, keep eating gluten until the result.

A newly diagnosed coeliac: follow a strict gluten-free diet, see a dietitian and check for nutritional deficiencies.

A person who still has symptoms after months gluten-free: review hidden gluten and talk to your doctor.

Key points to remember

Test before you cut gluten. Base your plan on naturally gluten-free whole foods, read labels carefully and prevent cross-contamination. A balanced gluten-free diet is nutritionally complete with planning. Our nutrition team can guide you.
