Choose a snack bar by the specific allergen that needs to be avoided, rather than treating a general free-from, vegan or protein label as enough. Check the current pack’s ingredients and precautionary allergen warnings, then check the school’s packed-lunch policy: a gluten-free bar can still contain peanuts, milk or soya. If those checks are satisfied, compare fibre, sugars and salt in the portion you plan to pack.
Match the bar’s current label to the child’s particular exclusions. Read both the ingredients and any precautionary warning for the relevant allergen; a claim about gluten does not answer a question about nuts, milk or soya.
Check the school’s own packed-lunch policy as well as the child’s dietary requirements. A bar that meets a gluten-free requirement can still contain nuts or carry a nut warning.
Once allergen and school-policy requirements are met, compare the stated fibre, sugars and salt per bar. A protein or wholegrain claim does not tell you everything about the bar or the rest of the packed lunch.
Start with the required allergen exclusion and the school’s rules; compare nutritional information only among bars that pass those checks.
| Priority | What to check | Your needs |
|---|---|---|
| Specific allergens | Look for a claim covering the exact allergen to avoid. Read the current ingredients and any relevant ‘may contain’ warning; a gluten-free claim does not cover nuts, milk or soya. | I need the label to address the child’s particular exclusions, not just display a broad free-from or vegan claim. |
| School policy | Check the individual school’s packed-lunch and allergy policy. Consider both nut ingredients and precautionary nut warnings when that policy makes them relevant. | Even if a bar fits the child’s own diet, I need to know whether it can go into this school’s lunchbox. |
| Everyday comparison | Compare fibre, sugars and salt for the portion being packed. Do not use a protein, oat or wholegrain description in place of the allergen checks. | Once the bar meets the allergy and school requirements, I want to compare what each bar contributes to the packed lunch. |
A claim applies to the allergen it names. Nature Valley’s Peanut & Chocolate Protein bar illustrates the distinction: its gluten-free positioning does not remove its peanut, milk or soya ingredients.
Identify the exact allergen to avoid, then read the current pack’s ingredients and precautionary warnings for that allergen.
A bar that fits one child’s dietary requirements may conflict with the school’s packed-lunch policy, particularly where nuts are a concern.
Ask the school about its policy before packing a bar with nut ingredients or a nut warning.
Oat and wholegrain wording is not a gluten-free claim. Nature Valley says its Crunchy + Fibre bars contain gluten and may contain wheat gluten.
If gluten must be avoided, look for an explicit claim on the current product pack and check other relevant allergens separately.
A familiar flavour or similar-looking multipack is not a substitute for checking the bar being packed.
Read the physical pack again when buying or packing it, especially after a packaging, flavour or multipack change.
These brand examples show why the exact product and flavour matter more than the name on the range.
Nature Valley sells several snack-bar formats with different recipes. Its own UK product information must be read at product level.
Graze offers oat-based and other snack formats; its range should not be treated as uniformly free from a particular allergen.
Alpen’s published allergen information concerns its products, not a reason to assume that a snack bar from the brand meets a free-from requirement.
These oat and protein bar options are relevant to a gluten-free search, but their nut, milk and soya considerations differ. Check each current pack against the child’s requirements and the school’s policy before choosing one for a packed lunch.

Consider this oat flapjack if gluten avoidance is the starting requirement. Soya is a stated limitation, and nut precautionary information needs checking on the physical pack before deciding whether it fits an allergy requirement or school policy.

This nut bar is an option to assess for gluten avoidance only if nuts are permitted by the school and meet the child’s requirements. Its product information also flags milk and soya; check the current pack for the full ingredients and warnings.

Nature Valley describes this bar as gluten free, but lists peanut, soya and milk ingredients and says it may contain other tree nuts. It therefore needs a separate school-policy check and is not an option for avoiding those listed allergens.

These oat bars are presented as gluten free, while the product information flags possible milk, nuts, peanuts and soya. Read the current pack before deciding whether its warnings fit the child’s requirements or the school’s policy; compare the sugars per bar if considering it as a regular lunchbox snack.

The named hazelnut and pecan ingredients make this an option to consider only where nuts meet the child’s requirements and the school’s policy. The product information also flags almonds and possible peanut, milk and soya presence; check the current pack alongside any gluten-free wording.
No. A gluten-free claim addresses gluten, not nuts. Nature Valley describes its Peanut & Chocolate Protein bar as gluten free but lists peanuts among its ingredients and says it may contain other tree nuts, so check the current pack for the allergen that matters to the child.
No. Those labels do not replace an allergen-specific check. Read the ingredients, any relevant free-from claim and precautionary warnings on the current snack-bar pack.
It warns of possible unintended presence of the named allergen. UK precautionary allergen labelling guidance addresses cross-contact risks, so read the warning for the child’s particular allergen rather than treating it as an ingredient or ignoring it.
Check the individual school’s packed-lunch and allergy policy before packing it. The Department for Education’s school-food guidance concerns food provided by schools in England; it should not be treated as the packed-lunch policy of every school in the UK.
Yes. Check the current physical pack each time against the child’s allergen requirements and the school’s policy, particularly if the flavour, packaging or multipack has changed.
