Hosts accommodating food allergies
Confirm the allergens that matter to each guest before choosing bars. Compare the exact product’s ingredients and precautionary statements with those requirements, and keep its wrapper available when serving.
Who needs to check what?
The useful starting point is the named guest’s requirement, rather than a ‘free-from’ claim chosen for the party as a whole.
Hosts seeking gluten-free or dairy-free snacks
Check what else is in each bar. Fruit-and-nut, oat and peanut bars can carry different ingredient and ‘may contain’ declarations even when they meet a gluten-free or dairy-free requirement.
Parents providing a child’s snack
Agree on the exact product with the host and check its current wrapper against the child’s requirements. Anaphylaxis UK advises discussing children’s dietary requirements with their parent or carer and the young person when planning food for an event.
What should you check before buying?
Confirm guest requirements first, compare the relevant type of bar, then make the final check against the packs you will serve.
Fruit-and-nut bars
Consider when: A named bar meets a guest’s gluten-free or dairy-free requirement and its nuts are acceptable for everyone who may eat it.
Watch for: Nakd says Berry Delight is gluten-free and dairy-free, but lists cashews and warns that it may contain peanuts and other nuts.
Oat-based bars
Consider when: The exact bar meets a confirmed gluten-free or vegan requirement and oats are suitable for the guest.
Watch for: TREK lists gluten-free oats and soya in Cocoa Oat, with a ‘may contain’ warning for peanuts, nuts and milk. The Food Standards Agency distinguishes gluten-free status from the need to declare oats.
Peanut bars
Consider when: A peanut-containing bar meets the specific guests’ requirements, rather than being offered as a shared free-from choice.
Watch for: Nature Valley lists peanuts, soya and milk in Protein Peanut & Chocolate and warns that it may contain other nuts.
| Priority | What to check | Your needs |
|---|---|---|
| Ingredients and allergens | Read the current ingredients list and its emphasised allergens. Check the exact flavour and pack rather than relying on a brand-wide claim. | I need to know what is in the bar each guest could be given, not just what its front label says. |
| ‘May contain’ wording | Look for precautionary statements separately from ingredients. The Food Standards Agency explains that ‘may contain’ can communicate possible unintentional presence of a regulated allergen. | Where a guest has an allergy, I want to discuss the exact warning with them or their parent or carer before offering the bar. |
| Meaning of free-from claims | Check gluten, oats, milk, soya, peanuts and relevant nuts against the individual requirement. A gluten-free oat bar is not oat-free; vegan wording does not replace a milk-allergen check. | A gluten-free choice may work for one guest, while another needs to avoid an ingredient or precautionary warning on that same bar. |
| Serving the right bar | Keep each product identifiable in its original wrapper. Recheck the purchased pack if an earlier shopping list or online image informed your choice. | I want each guest or parent to be able to identify the precise bar before it is eaten. |
Which mistakes are easy to make?
-
Taking one free-from claim to mean suitable for everyone
Nakd lists cashews in its gluten-free, dairy-free Berry Delight bar. Nature Valley lists peanuts, soya and milk in its gluten-free Protein Peanut & Chocolate bar. Each claim addresses only part of a guest’s possible requirements.
Collect the specific requirements first and compare each candidate’s current ingredient and precautionary declarations with them.
-
Assuming gluten-free also means oat-free
The Food Standards Agency says oats still need to be emphasised as an allergen in an oat-containing product labelled gluten-free.
Clarify whether the guest needs to avoid gluten, oats, wheat or a combination before selecting an oat bar.
-
Missing a ‘may contain’ warning
Precautionary wording concerns possible unintentional allergen presence, not just ingredients in the recipe. TREK’s Cocoa Oat bar, for example, carries a warning for peanuts, nuts and milk.
Leave the wrapper with the product and discuss relevant warnings with the guest or their parent or carer before serving.
-
Using an old listing as the final label check
Nature Valley advises checking packs because products can be reformulated. An earlier product description may not describe the bar bought for the party.
Read the exact multipack and the wrappers you will hand out, particularly when buying a familiar product in a different flavour.
What do the brand examples show?
These examples show why suitability belongs to a particular product and flavour, not to a brand name.
Nakd
Nakd describes Berry Delight as a vegan, gluten-free and dairy-free fruit-and-nut bar.
- The named bar offers a specific product to assess for those three requirements.
- Nakd lists cashews and a warning for peanuts and other nuts; it is not a nut-free choice.
TREK
TREK describes Cocoa Oat as a vegan flapjack made with gluten-free oats.
- TREK states that the 50g Cocoa Oat bar contains 9g plant protein.
- It contains soya ingredients and may contain peanuts, nuts and milk; oats also need their own check.
Nature Valley
Nature Valley has different ingredient and allergen declarations across its snack-bar products.
- Nature Valley describes Protein Peanut & Chocolate as gluten-free and lists approximately 10g protein per 40g bar.
- That bar contains peanuts, soya and milk and may contain other nuts. Its Oats & Honey bars have a different precautionary declaration, so check the exact flavour.
Eat Natural
Eat Natural’s named fruit and protein bars illustrate distinct peanut, nut and milk checks.
- Eat Natural describes its Peanut Soft Fruit Bar as gluten-free and vegan.
- That bar contains peanuts and may contain soya, milk, almonds, hazelnuts and cashews. Its Cocoa & Peanut protein bar also contains peanuts and almonds.
Graze
Graze describes a snack range using ingredients including wholegrains, fruit and nuts.
- Check a named Graze product and flavour against the party’s confirmed requirements.
- The brand description alone does not establish that a particular bar meets a free-from requirement.

Birthday-party snack bar FAQs
Do packaged snack bars in the UK have to show allergens?
For prepacked food, the Food Standards Agency says the packaging must carry an ingredients list and emphasise allergens present each time they appear in that list. Read the current pack of the exact bar you plan to serve.
Does gluten-free mean an oat bar is oat-free?
No. The Food Standards Agency says gluten-free food must contain no more than 20 mg/kg gluten as sold to the final consumer, while oats in the product still need to be emphasised as an allergen. Clarify whether the guest needs to avoid gluten, oats or both.
Does a vegan bar settle a milk-allergy check?
No. TREK describes Cocoa Oat as vegan but warns that it may contain milk. Check the exact bar’s ingredients and precautionary statement against the guest’s requirements.
What if a child coming to the party has a food allergy or coeliac disease?
Discuss the child’s requirements with their parent or carer before choosing food. Anaphylaxis UK also advises involving the young person and assessing the event; an agreed exact product is more useful than assuming a broad free-from category will suit them.
What does ‘may contain’ mean on a snack bar?
The Food Standards Agency describes it as precautionary labelling for an allergen that could be unintentionally present. It differs from an ingredient declaration, so discuss a relevant warning with the guest or their parent or carer rather than treating it as irrelevant.
