Shoppers avoiding gluten
Look for an explicit gluten-free claim rather than relying on the cereal named on the wrapper. Check the current ingredients too: a gluten-free bar can still contain oats or other allergens.
Who needs to check what?
People avoiding a specific allergen
Start with the allergen you need to avoid. Read both the ingredients and the precautionary “may contain” statement on the individual pack; gluten-free bars can still list peanut, milk, soya or nuts.
Desk-lunch shoppers comparing portions
Once a bar fits your ingredient requirements, compare its portion size and the nutrition information per bar. Protein or fibre figures describe that product’s serving, not whether it meets an allergen requirement.
What to check before choosing
Set your ingredient requirements first, then compare the portions and formats of bars that meet them.
| Priority | What to check | Your needs |
|---|---|---|
| Gluten-free label | Look for an explicit claim on the exact bar. Coeliac UK explains that “gluten free” means no more than 20 parts per million of gluten; the Food Standards Agency notes that oats must still be identified where relevant. | I need to avoid gluten, so an oat- or rice-based name alone is not enough to choose a bar. |
| Other allergens | Read the current ingredients for the allergen you avoid, then check any separate “may contain” statement. Do not treat a gluten-free claim as an all-allergen claim. | My choice also has to account for ingredients such as peanut, milk, soya or nuts, not just gluten. |
| Nutrition per bar | Compare the stated portion size and nutrition per bar on variants that meet your ingredient requirements. Keep per-bar and per-100g figures distinct. | If I am comparing bars for a desk lunch, I want to know what one bar provides rather than judge by the pack size. |
| Current pack | Check the label on the pack you will eat, including its ingredients and precautionary statement. Nature Valley and Kellogg’s advise checking current packaging because recipes can change. | A bar I have bought before still needs a fresh label check. |
Common label-reading mistakes
-
Reading “gluten free” as “free from all allergens”
Nature Valley’s Protein Peanut & Chocolate bar contains peanut, soy and milk and may contain tree nuts. TREK Cocoa Oat lists soya and may contain peanuts, nuts and milk.
Check the exact ingredients and precautionary statement against the allergens you need to avoid.
-
Assuming the cereal name establishes gluten-free suitability
Alpen says its products contain gluten from wheat, barley or oats. Kellogg’s Special K Red Berry Bar lists barley and wheat among its allergens.
If you need to avoid gluten, look for an explicit gluten-free label on the particular bar and read its ingredients.
-
Relying on an older product listing
A familiar bar’s ingredients may change; Nature Valley and Kellogg’s both advise shoppers to check current pack information.
Use the label on the pack you are buying as your final ingredient check. If it is unclear, do not assume an earlier listing still describes that bar.
Brand ranges to compare
A brand name does not establish the allergen status of every variant; compare the exact bar and its current label.
Nature Valley
Its range includes Crunchy, Protein and Oaty & Crispy bars, with gluten-free claims on specified Protein variants.
- Nature Valley lists its Protein Peanut & Chocolate bar as gluten free, with 10g protein and 4g fibre per bar.
- That variant contains peanut, soy and milk and may contain tree nuts. Check the current pack if these allergens matter to you.
TREK
TREK offers oat flapjacks and protein bars, including the Cocoa Oat variant made with gluten-free oats.
- Cocoa Oat offers a plant-based flapjack format for shoppers comparing portable bars.
- Its ingredients include soya, and its precautionary statement names peanuts, nuts and milk.
Eat Natural
Eat Natural lists a range of gluten-free bars in fruit-, nut- and protein-based formats.
- The gluten-free range gives shoppers different recipes to compare.
- Gluten free does not mean nut free: Tesco’s ingredients listing for the Apple Soft Fruit Bar includes almonds.
Alpen
Alpen bars are a comparison point for shoppers who do not need to avoid gluten.
- Alpen says its products contain gluten from wheat, barley or oats, so its brand name is not a substitute for a gluten-free claim.
Kellogg’s
Check individual Kellogg’s bar recipes rather than applying one allergen assumption across the range.
- Special K Red Berry Bar lists barley, oats, milk, soy and wheat, and may contain gluten from other cereals.
- Kellogg’s advises checking the current pack because recipes can change.
Graze
Graze makes oat flapjacks and other snacks using ingredients that can include grains, fruit and nuts.
- For any free-from requirement, check the claim and allergen information on the exact Graze product rather than relying on the brand or flapjack format.

Questions about free-from bars
What does “gluten free” mean on a cereal bar?
Coeliac UK explains that a food labelled “gluten free” contains no more than 20 parts per million of gluten. The claim does not exclude other allergens: check the bar’s ingredients and any precautionary statement as well.
Is an oat-based bar necessarily gluten free?
No. The cereal named on a wrapper is not a gluten-free claim. If you need to avoid gluten, look for an explicit claim on the exact product; oats and other allergens may still appear in its ingredients.
Can a gluten-free bar contain peanut, milk, soya or nuts?
Yes. Nature Valley’s gluten-free Protein Peanut & Chocolate bar contains peanut, soy and milk and may contain tree nuts. Check every allergen relevant to you on the current pack, not just the gluten-free claim.
What should I check on a UK prepacked-for-direct-sale lunch?
For prepacked-for-direct-sale food, the Food Standards Agency and Food Standards Scotland state that, since 1 October 2021, the UK label must show the food name and a full ingredients list with the 14 regulated allergens emphasised. This matters for a bar packed for direct sale by an on-site café or similar outlet; read that item’s label rather than assuming it matches a branded retail bar.
Why check a bar’s label if I have bought it before?
Recipes can change. Nature Valley and Kellogg’s advise checking current pack information, so read the ingredients and any “may contain” statement on the bar you are buying.
