How Can I Be Sure I’m Buying Gluten Free Products?

How Can I Be Sure I’m Buying Gluten Free Products?

Here at Glutafin, we’ve been working hard to support people on a gluten free diet for many years. We provide a wide range of gluten free products on prescription (subject to local prescribing), including delicious gluten free fresh bread. You can rest assured that all Glutafin products are produced to meet strict gluten free standards and are suitable for people with coeliac disease.

But what about your other food choices? How can you be sure that you are buying gluten free products at the supermarket, and what should you be looking out for as you choose your food?

Understanding Gluten Free Labels in the UK

Last month, we looked in detail at the UK labelling rules on gluten free products. That article explains exactly what to look for on product labels, including:

  1. Known allergens – including those containing gluten. These will be highlighted in bold, highlighted or italic font on the ingredients list
  2. Grains – look for grains such as wheat, barley, rye and spelt. It is important  to also avoid foods containing oats, unless they are specifically listed as gluten free oats.
  3. Gluten free – products listed as gluten free are guaranteed to contain  less than 20ppm of gluten – a safe level for coeliacs.
  4. Crossed grain symbol – introduced by Coeliac UK, this symbol shows products have been independently tested.

Less Obvious Sources Of Gluten

Gluten is often contained in foods that you might not suspect. For this reason, always refer to the ingredients deck to confirm the presence of gluten-containing ingredients. Examples include:

  1. Processed meat
  2. Soups
  3. Sauces & dressings
  4. Ready meals
  5. Oven chips
  6. Crisps
  7. Confectionary
  8. Spice mixes/ flavourings

Keep It Simple

Shorter ingredient lists make it easier to spot potential sources of gluten, so keeping it simple helps you to keep your shopping safe. Buying the basics and cooking your own meals from scratch will give you even more confidence and control over the ingredients, and there are plenty of naturally gluten free foods to choose from.

Naturally Gluten Free Products

There’s a wide range of foods that are naturally gluten free, which you can enjoy with complete confidence. These include:

  1. Fresh meat and poultry
  2. Fresh fish and seafood
  3. Eggs
  4. Fruit and vegetables
  5. Potatoes, rice and quinoa
  6. Beans, legumes, nuts and seeds
  7. Plain dairy products including milk, yoghurt, butter and cheese

Look Out for Cross Contamination

Some manufacturers use the same production line to process and pack gluten-free and gluten-containing foods. Check food packaging for any ‘may contain’ statements that relate to wheat, rye, barley and oats, and avoid foods where these are used. If you are unsure, contact the manufacturer for more information.

Better To Be Safe Than Sorry

At the end of the day, it’s always better to be safe than sorry. As the 20ppm limit shows, even small amounts of gluten can trigger the autoimmune response associated with coeliac disease, whether or not obvious symptoms occur.

Unless you know that a food is naturally gluten free, or it is clearly labelled as a gluten free product, then it is always better to err on the side of caution and choose something else.

Frequently Asked Questions

Is ‘wheat-free’ the same as ‘gluten-free’? 

No. Wheat is not the only source of gluten so ‘wheat free’ products may still contain gluten from barley or rye. If you are following a gluten free diet, you should look for the words ‘gluten free’ or the crossed grain symbol. If these claims aren’t present, check the ingredients deck for gluten-containing grains.

Are oats gluten free? 

Oats themselves do not contain gluten. However, they are often contaminated with wheat during growing, harvesting and processing. It is important to only choose oats that are certified gluten free if you are following a gluten free diet.

What does ‘may contain traces of gluten’ mean? 

This is a warning used on products that do not contain gluten as an ingredient, but which may have been contaminated during processing. For example, they have been produced at a factory that also produces wheat or barley-based products.

Where can I find certified gluten free products I can trust?
