Certified gluten-free products: what to buy and how to check the mark

By the DieticiansWorldwide.com editorial team · checked 18 October 2026 · Shop by diet

How we chose (criteria)

This guide is about the shopping trolley. Why coeliac disease needs a strict, lifelong gluten-free diet, how to get tested first and where gluten hides are covered in our guide to the coeliac diet. Read that first if you are newly diagnosed.

Every named product here passed these tests:

1. It is listed in a certifier's own directory today. For the US we searched the GFCO Product Finder on 18 October 2026 and saw each product listed by name, brand and barcode. Each row links the exact search, so you can repeat it.
2. It is sold in the US or Canada according to the directory's sales-region field, or the listing names a US pack size.
3. It is an everyday staple or snack: crackers, popcorn, bars, bread, pasta, cereal and oats. Specialist baking ingredients and bulk catering packs were left out.
4. No one paid to appear. Products are grouped by type, not ranked.

Where a certifier's product directory is open only to members, we have not named products from it and explain how you can check instead.

Why choose certified rather than "gluten-free" alone

A gluten-free claim is a legal promise made by the manufacturer. Certification adds a second, independent check.

• The law sets the limit. In the US, a food labelled gluten-free must contain less than 20 parts per million (ppm) of gluten and must not be made from a gluten-containing grain unless it has been processed to remove the gluten (21 CFR 101.91). The EU sets the same 20 mg per kg ceiling (Regulation (EU) No 828/2014). The FDA describes "gluten-free" as a voluntary claim that manufacturers may use if they meet all the requirements of the rule (FDA, gluten-free labeling), so the claim rests on the company's own controls and testing.
• A certifier audits the process. Certification programmes review ingredients, inspect or audit the factory and require testing, then license a mark that the brand prints on the pack. That makes them most useful for products with many ingredients, made in factories that also handle wheat.
• Some certifiers set a tighter limit. GFCO requires starting ingredients and finished products to test below the gluten-free threshold of the country of sale or 10 ppm, "whichever is lower", against an 80-point standard, and it prohibits oats where national rules require it, such as Australia and New Zealand (GFCO).

The three marks compared

Coeliac UK says its licence requires products to meet no more than 20 ppm of gluten, an independent audit of the manufacturing site, and annual renewal (Coeliac UK, Crossed Grain for packaged products). Coeliac Australia explains that a gluten-free claim in Australia requires "no detectable gluten", and that foods containing oats, or malted gluten-containing cereals, cannot carry it (Coeliac Australia, making a gluten-free claim).

What a gluten-free mark does not tell you

A certification mark answers one question: is the gluten in this product below a set limit, under controls someone has audited? It is easy to read more into it than that.

• It is not an allergen-free claim. Many certified products contain milk, egg, soy, nuts or sesame. If you have another allergy or intolerance, the allergen statement still decides.
• It is not a nutrition rating. A certified cracker can be high in salt and a certified bar high in sugar. The mark says nothing about either.
• It does not cover what happens after the pack is opened. A certified loaf toasted in a shared toaster is no longer the product that was tested. Kitchen habits matter as much as purchases.
• It does not mean the rest of the range is certified. Brands often certify some lines and not others, or one pack size and not another made in a different factory.
• It is not a treatment claim. Choosing certified products supports a gluten-free diet; it does not replace diagnosis, follow-up blood tests or dietetic review.

Price is the other trade-off. Certified specialist products usually cost more than naturally gluten-free staples, so many people keep certified items for bread, pasta, cereal and baked snacks, and fill the rest of the trolley with plain rice, potatoes, pulses, meat, fish, eggs, dairy, fruit and vegetables. That pattern also tends to raise fibre and lower salt.

GFCO-certified gluten-free snacks

All products below were listed in the GFCO Product Finder on 18 October 2026 for the US (and Canada where shown).

Reading a GFCO listing

Each GFCO entry shows the product name, brand, barcode (UPC), category and the sales region the manufacturer has declared. The barcode is the most reliable match: the same cracker can appear several times, once for each pack size or country, and only the listed versions are covered. If your pack's barcode is missing from the results, search by brand to see what is listed, and check the mark on the pack. Some entries leave the region or category blank, which is another reason to rely on the mark and the barcode together rather than on any single field.

GFCO-certified staples: bread, pasta, cereal and oats

Snacks are the easy part. The products people with coeliac disease most often miss are the everyday staples, which is where certification is most valuable.

Two things to note about this table. First, a brand appearing here does not mean all its products are certified: GFCO lists products one by one, often by pack size, so check the exact item. Second, certified oats are free of contamination with wheat, barley and rye, but some people with coeliac disease still react to oats themselves. The coeliac diet guide linked above explains when to try them, and it is a decision to make with your healthcare team.

How to check a label yourself

Plenty of suitable food is never certified. When there is no mark, work through the label in this order.

1. Look for the words "gluten-free" on the pack. In the US, UK, EU and Canada that is a legal claim at 20 ppm; in Australia it means no detectable gluten.
2. Read the ingredient list for wheat, barley and rye in every form: spelt, khorasan (Kamut), durum, semolina, farro, triticale, malt, malt extract, malt vinegar and brewer's yeast. In the UK and EU, cereals containing gluten are emphasised, usually in bold.
3. Check oats separately. Unless the oats are labelled gluten-free or certified, assume they may be contaminated.
4. Read "may contain" warnings, but do not rely on their absence. Precautionary labels are voluntary in most countries.
5. Check the barcode or pack size against the directory if a mark is present. Certifiers often list each size separately.
6. Look past gluten to nutrition. Gluten-free substitutes are often lower in fibre and can be high in salt. In the US, "low sodium" means 140 mg or less per serving (21 CFR 101.61), and a "good source of fiber" provides at least 10% of the Daily Value.
7. Re-check products you buy every week. Recipes and factories change; certifiers delist products that leave their programme.

Naturally gluten-free foods that rarely need a mark

Single-ingredient foods are not normally certified because there is little to check. The exception is grains such as oats, buckwheat and millet, which can pick up wheat in fields and mills; buy those labelled gluten-free where you can.

Gluten-free snacks that also fit other diets

Many people managing coeliac disease also manage another condition. A few points from the products above:

• Low FODMAP. Gluten-free and low FODMAP overlap but are not the same. Almond-flour and chickpea-based products can be high in FODMAPs in larger servings. If you also have IBS, use our low FODMAP snacks guide, which lists products certified for FODMAPs.
• Fibre. Seed crackers, chickpea pasta and oats raise fibre more than rice crackers or crisped rice. Our fibre calculator gives your daily target, and our high-fibre foods list shows naturally gluten-free sources.
• Protein. Chickpea and lentil pastas provide more protein than rice or corn pasta. For snack ideas, see our high-protein snacks.
• Iron. Iron deficiency is common around diagnosis. Fortified gluten-free cereals help, but if your levels are low, read our guide to iron supplements before buying any.

Outside the US

The rules and the marks change at the border, and so does what is on the shelf.

• United Kingdom. The Crossed Grain is the mark to look for. Coeliac UK says it appears on more than 21,000 products across Europe. Its product search, the Food and Drink Guide, is available to members and through the Live Well Gluten Free app (Coeliac UK, Food and Drink Guide), so we could not check individual products and have not named any. Supermarket own-brand "free from" ranges are widely available. Our United Kingdom country guide explains how dietitians work in the NHS, including prescription gluten-free staples.
• Canada. Health Canada considers that gluten-free foods with levels not exceeding 20 ppm, as a result of cross-contamination, meet its health and safety intent (Health Canada, position on gluten-free claims). Several GFCO listings above include Canadian packs.
• Australia and New Zealand. The law is stricter: no detectable gluten, and no gluten-free claim on oats. Coeliac Australia's endorsed products directory can be searched by brand and category; on 18 October 2026 it listed brands including Barilla, Helga's Continental Bakehouse, Abbott's Bakery, Kellogg's and Spliits. Check the individual product in the directory before you buy, because endorsement is product by product. Our Australia country guide covers dietetic care there.

Online retailers ship across borders, so a US pack can arrive in the UK or Australia. The label and the mark on that pack follow the rules of the country it was made for.

When to see a dietitian

Use this list to make shopping quicker, not to replace advice. Book a registered dietitian if:

• you have just been diagnosed, or you went gluten-free without a diagnosis;
• symptoms continue despite a careful gluten-free diet;
• your blood tests show low iron, folate, vitamin B12 or vitamin D;
• you also follow another diet, such as low FODMAP, vegetarian or diabetes-related eating;
• you are pregnant, feeding a child with coeliac disease, or worried about your weight;
• shopping or eating out has started to feel frightening.
