Shoppers avoiding gluten
Look for a gluten-free claim on the exact bar, then read its ingredients for any other restriction that matters to you.
Who needs to check what?
Shoppers avoiding a named allergen
Check the ingredients and precautionary statement for that allergen. A gluten-free bar can still contain peanuts, milk, soya or oats.
Vegan shoppers with an allergy to consider
Check allergen information separately from the vegan description. TREK Cocoa Oat, for example, is vegan but carries a precautionary statement for milk, peanuts and nuts.
What matters when choosing?
Start with the ingredient you must avoid, then check the claim and allergen information for the precise flavour and pack.
| Priority | What to check | Your needs |
|---|---|---|
| Gluten-free claim | Look for the claim on the exact product. The Food Standards Agency defines gluten-free as no more than 20 mg/kg gluten; check the current pack rather than assuming an oat bar qualifies. | I need a bar labelled gluten-free, not just one made with an ingredient that sounds suitable. |
| Other allergens | Read the full ingredients and any ‘may contain’ statement. Nature Valley Protein Peanut & Chocolate contains peanuts, soya and milk and may contain tree nuts, according to Nature Valley UK. | Gluten is not my only concern: I need to check whether the bar contains, or may contain, the ingredient I avoid. |
| Vegan status | Check the vegan description separately from the allergen information. TREK describes Cocoa Oat as vegan, but lists soya and a precautionary statement for peanuts, nuts and milk. | I want a vegan bar, while still checking the allergen statement for my particular restriction. |
| Pack size | Check the number of bars and weight per bar when comparing multipacks. Make sure the exact flavour and pack still meet your ingredient requirements. | For a budget shop, I want a pack size I can use without compromising on the exclusion that matters to me. |
Mistakes to avoid
-
Assuming gluten-free means free from every allergen
A gluten-free bar may still contain another ingredient you need to avoid. Nature Valley Protein Peanut & Chocolate contains peanuts, soya and milk and may contain tree nuts, according to Nature Valley UK.
Name your required exclusion first, then read the ingredients and allergen statement for the exact flavour and pack.
-
Using vegan as an allergen check
TREK describes Cocoa Oat as vegan, but states that it contains soya and may contain peanuts, nuts and milk.
Check ingredients and precautionary allergen information even when a bar is labelled vegan.
-
Skipping the ‘may contain’ statement
The Food Standards Agency explains that precautionary allergen labelling communicates possible unintended presence of an allergen. It is different from a listed ingredient, but still matters to an allergy decision.
Include that statement when checking the pack against the allergen you need to avoid.
Brand references
Claims and ingredients vary by product, so use these examples to identify what to check on the bar you are considering.
Nature Valley
Nature Valley UK describes its Protein Peanut & Chocolate bar as gluten-free.
- The checked bar weighs 40g; Nature Valley UK states that it contains around 10g protein and 4g fibre.

- Ingredients vary: Eat Natural lists varieties with peanuts, several tree nuts, yoghurt or soya. Check the specific bar.
Graze
Graze offers Oat Boost flapjacks; Tesco describes the checked Cocoa Vanilla Oat Boosts as suitable for vegans.
- Do not infer gluten-free suitability from the brand, the oat-based name or a vegan description. Check the precise flavour’s label.
Alpen
Alpen is a cereal-bar brand, but its name is not a shortcut for a free-from choice.
- Alpen states that all its products contain wheat, barley or oats, and that some are made where peanuts and nuts are used.
Kellogg's
Kellogg's offers Rice Krispies Snack Bars among its cereal-bar products.
- The checked Rice Krispies Snack Bar lists barley malt extract, wheat gluten, milk and soya. Check other varieties individually rather than assuming they share the same ingredients.

Questions about free-from bars
What does gluten-free on a cereal bar mean?
The Food Standards Agency defines gluten-free food as containing no more than 20 mg/kg gluten. The claim addresses gluten; it does not tell you whether the bar contains other allergens, so check those separately.
Does gluten-free mean an oat bar is suitable for someone avoiding oats?
No. The Food Standards Agency says oats must still be emphasised as an allergen even when a food is labelled gluten-free. Read the ingredients for the exact bar.
Can I assume a vegan cereal bar has no milk allergen warning?
No. TREK describes Cocoa Oat as vegan but states that it may contain milk, peanuts and nuts. Check both the ingredients and any precautionary statement for the specific bar.
Should I check the pack after reading an online listing?
Yes. Use the listing to narrow your choices, then read the current pack’s ingredients and allergen information before choosing. Nature Valley UK advises checking the pack because product formulations can change.
