Travellers avoiding a named allergen
If gluten, milk, peanuts, tree nuts or soya matters to you, compare the full declaration on each bar with your restriction. A claim about one allergen does not settle the others.
Who needs to check what?
Shoppers who need gluten-free snacks
Look for an explicit gluten-free claim on the product you plan to pack. Oat-based, wheat-free, lactose-free and vegan descriptions answer different questions.
Vegan or dairy-free travellers who can eat nuts
Fruit-and-nut bars and some flapjacks may fit these preferences, but check the exact recipe and precautionary statements if peanuts or other allergens also matter.
What should you check before choosing?
Start with the requirement you cannot compromise on, then read the ingredients and precautionary statements on the exact pack.
| Priority | What to check | Your needs |
|---|---|---|
| Allergen declaration | Read the ingredients for allergens used in the recipe. Check “may contain” statements separately for possible unintended presence, as described by the Food Standards Agency. | I need to know whether the exact bar conflicts with an allergen I avoid, regardless of its pack-front claim. |
| Gluten-free label | Look for an explicit gluten-free claim. Coeliac UK explains that foods labelled gluten free must contain no more than 20 parts per million of gluten; do not infer that claim from oats, vegan status or lactose-free wording. | If I need a gluten-free bar, I want the claim on the product itself rather than an assumption about its ingredients. |
| Other dietary claims | Check vegan or dairy-free wording against your requirement, then read the nut, peanut, soya and milk declarations. Check the protein source on protein bars. | A vegan or dairy-free choice still has to fit any other allergens I avoid. |
| Holiday packing | Keep the wrapper available so you can check the product information. For flights, check the departure airport, airline and destination requirements; UK government guidance says food in hand luggage can lead to an additional security check. | I want to check what I am carrying before departure and be able to identify a bar’s ingredients while away. |
Common mistakes to avoid
-
Reading “free from” as free from every allergen
A gluten-free bar can still contain peanuts, milk, soya or tree nuts. Nature Valley Protein Peanut & Chocolate, for example, is described as gluten free by Nature Valley, while its Joybuy allergen declaration lists peanuts, soya and milk.
Identify the allergen you need to avoid, then check the ingredients and precautionary statements on the current pack.
-
Assuming an oat or lactose-free bar is gluten free
Nature Valley says its Crunchy Oats & Dark Chocolate bar is not suitable for a gluten-free diet. Alpen says its products contain gluten from wheat, barley or oats.
When gluten-free suitability matters, choose a product explicitly labelled gluten free rather than relying on its cereal type or another dietary claim.
-
Choosing by bar type instead of the recipe
Fruit-and-nut bars may contain tree nuts, while protein bars can contain peanuts, soya or milk. The Joybuy declaration for nākd. Cocoa Orange lists cashew and precautionary warnings for other allergens.
Check the exact flavour and pack. Do not choose nākd. Cocoa Orange if its cashew content or precautionary warnings conflict with your requirements.
-
Leaving travel checks until departure
UK government guidance says food in hand luggage can obstruct security images and require a manual bag check.
Keep product information with the bars and check the requirements for your airport, airline and destination before travelling.
Brand ranges to check
These brand examples show why claims need checking at product level; mentioning a range does not make every bar in it suitable for the same restriction.
nākd.
nākd. describes its fruit-and-nut bars as vegan, gluten-free, wheat-free and dairy-free. They are not a route for avoiding nuts as a category.
- The brand identifies several dietary claims for its fruit-and-nut range.
- Joybuy lists cashew in nākd. Cocoa Orange and gives precautionary warnings for other nuts, peanuts and soya.
TREK
TREK describes its Original Oat flapjack as vegan and gluten free, with 10 g of plant protein.
- Original Oat has an explicit gluten-free claim from TREK.
- TREK says Original Oat may contain peanuts, nuts and milk. Check each other flavour separately.
Eat Natural
Eat Natural has a dedicated UK selection of gluten-free cereal bars.
- The selection gives shoppers a way to identify products presented as gluten free.
- Check the ingredients of the individual bar if nuts or peanuts matter to you.
Nature Valley
Gluten-free suitability differs between Nature Valley products: the brand describes Protein Peanut & Chocolate as gluten free but says Crunchy Oats & Dark Chocolate is not suitable for a gluten-free diet.
- Nature Valley lists around 10 g of protein and around 4 g of fibre per Protein Peanut & Chocolate bar.
- Joybuy lists peanuts, soya and milk in that protein bar, with a “may contain nuts” warning.
Graze
Graze offers oat-based snacks, but the allergen information needs checking on each product.
- Its Oat Boost range provides an oat-based flapjack option.
- Tesco’s listing for Graze Honey Oat Boost warns that the food may contain several allergens, including peanuts, milk, nuts and cereals containing gluten.
Alpen
Alpen is relevant to checking, rather than assuming, gluten-free suitability.
- Alpen’s FAQ says its products contain gluten from wheat, barley or oats.
Snack-bar options on Joybuy
These oat, fruit-and-nut and peanut bars offer different starting points for holiday snacks. Check each exact pack against your gluten-free, vegan or allergen requirements before choosing; the bar type alone cannot establish suitability.

Questions about free-from snack bars
Does “gluten free” mean a bar is suitable for every allergy?
No. A gluten-free claim addresses gluten, not every allergen. Nature Valley describes its Protein Peanut & Chocolate bar as gluten free, while Joybuy lists peanuts, soya and milk in its allergen declaration and a warning that it may contain nuts. Check the exact pack against each allergen you avoid.
What does “gluten free” mean on a UK snack bar?
Coeliac UK explains that food labelled gluten free must contain no more than 20 parts per million of gluten. Look for that explicit claim rather than assuming an oat-based, vegan or dairy-free bar is gluten free.
What should I do with a “may contain nuts” warning?
Treat it as distinct from nuts deliberately used as ingredients. The Food Standards Agency explains that precautionary allergen labelling communicates possible unintended presence; check the current pack and follow the advice you have been given for your allergy rather than relying on a free-from claim about another allergen.
Can food in hand luggage need an extra airport check?
Yes. UK government guidance says food can obstruct hand-luggage X-ray images and may require a manual bag check. Check your departure airport, airline and destination requirements before travelling.
Why check the exact flavour instead of the brand?
Products within a brand can have different allergen and gluten-free information. Nature Valley describes Protein Peanut & Chocolate as gluten free but says Crunchy Oats & Dark Chocolate is not suitable for a gluten-free diet, so read the label of the bar you intend to take.
