Who needs which checks?

The right bar depends on the guest’s requirement, not on a general free-from description.

Hosts serving gluten-free or vegan guests

Look for the relevant claim on the exact flavour’s current pack. An oat-based or fruit-based recipe alone does not establish either claim.

Hosts catering for a peanut, tree-nut, milk or soya allergy

Read the full ingredients and any precautionary allergen statement for each flavour. A bar labelled gluten-free or vegan can still contain, or carry a warning about, another allergen.

Hosts offering several individually portioned snacks

Keep each bar identifiable and compare its per-bar nutrition panel if portion size matters to your selection. Protein, fibre and natural wording does not replace the figures on the pack.

What should you check before buying?

Establish the dietary requirement first, then check the flavour-specific label and how guests will identify each bar at the buffet.

Priority What to check Your needs
Dietary claims Check the current pack for the required gluten-free, dairy-free or vegan claim. Apply it to the exact flavour, not every bar from the brand. I need a bar that meets a guest’s confirmed requirement, rather than one that merely sounds suitable from its ingredients.
Other allergens Read the ingredients for named allergens and check any may-contain statement. In particular, do not treat gluten-free or vegan as meaning nut-, peanut-, milk- or soya-free. If someone must avoid a specific allergen, I need to assess that allergen on every flavour I serve.
Nutrition per bar Compare serving size and the per-bar figures for sugars, saturated fat, energy, fibre or protein that matter to your choice. Check per 100g figures when comparing different-sized bars. When I put several sweet bars out, I want to compare their stated portions rather than rely on protein or natural wording.
Buffet identification Keep the original wrapper and its ingredient information with each type of bar. Identify flavours separately, particularly when their allergen statements differ. Guests should be able to tell which bar they are taking and check its label before eating it.

Common buffet mistakes

  • Treating gluten-free as free from every allergen

    Nature Valley Protein Salted Caramel Nut is described as gluten-free, but Nature Valley lists peanut, almond, soya and milk ingredients and says it may contain other tree nuts.

    Check the exact pack against each guest’s restriction, including its ingredients and may-contain statement.

  • Assuming vegan fruit-and-nut bars are nut-free

    Tesco’s product information lists cashews in nākd. Cocoa Delight and almonds in Eat Natural Apple Soft Fruit Bars. Their vegan and gluten-free descriptions do not remove those ingredients.

    Check named nuts and precautionary statements for the precise flavour before putting it out.

  • Using front-of-pack wording as a nutrition verdict

    In its November 2025 review of 458 snack bars sold by major UK retailers, Action on Salt & Sugar reported that 37% were high in sugars and 55% were high in saturated fat under UK front-of-pack thresholds. Those category figures do not describe any particular bar.

    Compare the nutrition panel and portion size of the bars you are considering, rather than assuming protein, fibre or natural wording settles the comparison.

  • Putting Alpen bars in a gluten-free selection

    Alpen says in its FAQ that all products in its range contain gluten from wheat, barley or oats.

    If gluten-free service is required, choose an exact product with an explicit gluten-free claim instead.

Brand ranges to check

Brand-level claims can point you towards a range, but the flavour’s current ingredients and allergen wording decide whether it meets a guest’s requirement.

nākd.

nākd. describes its Fruit & Nut Bars as vegan and gluten-, wheat- and dairy-free.

  • These claims may help when gluten-free, dairy-free and vegan requirements overlap.
  • They are not a nut-free claim: Tesco lists cashews in Cocoa Delight and warnings for soya, peanuts and other nuts.

TREK

TREK describes its Original Oat protein flapjack as vegan and gluten-free, with 10g plant protein per bar.

  • Original Oat offers an explicitly labelled vegan and gluten-free flapjack option.
  • TREK lists a may-contain warning for peanuts, nuts and milk on Original Oat; check the exact pack for all allergen information.

Eat Natural

Selected Eat Natural products, including the Apple Soft Fruit Bar listed by Tesco, are described as gluten-free and vegan.

  • The individually wrapped Apple bar can retain its own label at the buffet.
  • Tesco lists almonds in that bar, so it is not an option for a guest who must avoid almonds.

Nature Valley

Nature Valley has specified gluten-free protein-bar options, including Protein Salted Caramel Nut.

  • A stated gluten-free claim can address that particular requirement when the exact pack confirms it.
  • Nature Valley lists peanut, almond, soya and milk ingredients for Protein Salted Caramel Nut, plus a warning for other tree nuts.

Graze

Graze says all its snacks are vegetarian and most are vegan.

  • Its item-specific labels may help when looking for a vegetarian or vegan choice.
  • A general vegetarian or vegan statement does not establish gluten-free, dairy-free or nut-free status for a particular bar.

Alpen

Alpen is a cereal-and-bar brand, but its FAQ says every product in its range contains gluten from wheat, barley or oats.

  • For requirements other than gluten avoidance, assess the individual product’s current information.
  • Do not use the range for a buffet selection that must be gluten-free.

nākd. Blueberry Muffin Fruit & Nut Bars 4 x 35g

Frequently asked questions

Does a gluten-free bar work for every guest with an allergy?

No. A gluten-free claim does not address other allergens. Nature Valley says its gluten-free Protein Salted Caramel Nut bar contains peanut, almond, soya and milk; check the exact bar’s ingredients and precautionary statement against the guest’s confirmed allergy.

Does vegan mean a snack bar is free from allergens?

No. Vegan is not a complete allergen statement. Tesco describes nākd. Cocoa Delight as vegan and dairy-free but lists cashews and a warning for soya, peanuts and other nuts. Read the current wrapper for the flavour you plan to serve.

How can guests identify bars on a mixed buffet?

Keep each product’s wrapper and ingredient information with its serving, and separate flavours so their labels do not get mixed up. This is a practical way to help guests check a bar’s allergens; it does not make a product suitable for every guest.

Are fruit-and-nut bars necessarily lower in sugar?

No conclusion follows from the fruit-and-nut description alone. Compare the stated sugars per bar and serving size on the products you are considering. In a November 2025 review of 458 snack bars sold by major UK retailers, Action on Salt & Sugar found that 37% were high in sugars under UK front-of-pack thresholds; that figure cannot determine the classification of an individual bar.
