Office workers and commuters
A portable bar can make a mid-morning snack easy to carry. Compare protein per whole bar rather than relying on the word ‘protein’ on the front of the pack.
Who these bars may suit
Plant-based snackers
Check the vegan label alongside protein, fibre and sugars per bar. If you also need a gluten-free or dairy-free product, check those claims on the exact flavour rather than assuming they follow from ‘vegan’.
Allergen-aware shoppers
Protein bars in this selection can contain peanuts, other nuts, soya, milk or wheat, depending on the recipe. Read the current ingredients and ‘may contain’ statement for the flavour and pack you intend to buy.
What to compare before choosing
Compare one complete bar at a time: pack sizes differ, and a dietary claim does not tell you everything about the nutrition panel or allergens.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per bar | Read the grams of protein for one whole bar and its serving size. TREK lists 16g per 55g Biscoff bar; Nature Valley lists 10.4g per 40g Salted Caramel Nut bar. | I want to know how much protein the snack I actually eat provides, not just whether ‘protein’ appears in its name. |
| Fibre | Compare fibre for the same serving basis. TREK lists 12g per 55g Biscoff bar, Nature Valley 4.3g per 40g Salted Caramel Nut bar, and the Tesco listing for nākd. Peanut Butter Protein gives 6.8g per 45g bar. | If fibre matters to me as well as protein, I need both figures for the particular bar I am considering. |
| Dietary labels and allergens | Check vegan, gluten-free and dairy-free claims separately. Read the exact flavour’s ingredients and precautionary allergen statement. | I may need a particular dietary label, but I still need to check for ingredients or cross-contact warnings that matter to me. |
| Sugars and energy | Use the per-bar panel rather than assuming a protein or no-added-sugar label answers these questions. TREK lists 14g sugars and 227 kcal per 50g Cocoa Oat bar; the Tesco listing gives 13g sugars per 45g nākd. Peanut Butter Protein bar. | For a regular mid-morning snack, I want to see sugars and energy alongside protein. ‘No added sugar’ does not mean sugar-free. |
Buying mistakes to avoid
-
Reading ‘protein’ as a serving-size comparison
The word alone does not show how many grams a whole bar provides. For example, TREK lists 16g per 55g Biscoff bar, while the Tesco listing for nākd. Peanut Butter Protein gives 7.6g per 45g bar.
Compare the protein figure and serving size on each nutrition panel before deciding which amount meets your preference.
-
Assuming one dietary label covers every concern
A vegan, gluten-free or no-added-sugar claim addresses a particular characteristic, not every ingredient, allergen warning or nutrition value. Nature Valley’s gluten-free-labelled Salted Caramel Nut bar contains peanuts, soya, almonds and milk ingredients.
Read the current pack for the exact flavour, including its ingredients, nutrition panel and ‘may contain’ statement.
-
Choosing on protein alone
Bars with protein can differ in sugars and energy per serving. TREK’s Cocoa Oat panel lists 9g protein, 14g sugars and 227 kcal per 50g bar.
Compare the complete per-bar panel when sugars, fibre or energy also affect your choice.
