Office workers looking for a high-protein bar
If the aim is to keep a bar at your desk that qualifies for a UK high-protein claim, compare protein with energy per bar. A stated number of protein grams alone does not establish that claim.
Who these bars are for
Plant-based snack shoppers
TREK states that its High Protein Bars contain 15g plant-based protein per bar. That is a different range from its standard Protein Flapjacks; check the exact product when choosing between them or a fruit-and-nut bar.
People buying snacks for a shared office
When colleagues have different dietary requirements, check the current ingredient and allergen declarations for every bar in an assortment, including any may-contain statements.
What to check before choosing
Start with the protein claim and serving size, then compare the rest of the nutrition panel and the exact pack’s ingredients for the people who will eat it.
| Priority | What to check | Your needs |
|---|---|---|
| High-protein claim | Check protein and energy for the same bar. Under UK nutrition-claim rules, protein must provide at least 20% of the food’s energy for a high-protein claim. | I want a bar that meets the high-protein criterion, not just one with “protein” in its name. |
| Portion and nutrition | Compare energy, protein, sugars and fibre per bar, noting differences in bar weight. Read the ingredient list alongside the figures. | For an afternoon snack, I want to know what the whole bar contains rather than compare figures from different serving sizes. |
| Allergens | Read the exact pack’s highlighted ingredients and may-contain wording. Check peanuts, tree nuts, soy, milk and cereals containing gluten where relevant. | If I’m ordering for colleagues, I need each person to be able to check the bar they will receive. |
| Plant-based choices | Check the vegan statement and ingredients on the exact variety. Assess its protein and energy separately; a vegan claim is not a high-protein claim. | I’d choose a plant-based bar, but I still want to distinguish a high-protein option from a flapjack or fruit-and-nut bar. |
Buying pitfalls
-
Assuming “protein” means high protein
Protein grams alone do not establish whether a bar meets the UK high-protein criterion. Ocado lists 9g protein and 227 kcal for a 50g TREK Cocoa Oat Protein Flapjack, putting protein at about 15.9% of its energy.
For a high-protein requirement, check a current pack claim and nutrition panel. You can compare the panel using protein grams × 4 kcal divided by the bar’s total kcal.
-
Using dietary claims as the whole nutrition comparison
Vegan, gluten-free and no-added-sugar statements describe different attributes. Tesco lists 13g sugars per 45g nākd Peanut Butter Protein bar, despite its no-added-sugar description.
Compare energy, protein and sugars for the actual bar, then check ingredients and allergens separately.
-
Assuming a plant-based or gluten-free bar suits everyone
Nature Valley Protein Peanut & Chocolate contains peanuts, soy and milk and may contain tree nuts. Eat Natural’s cited Dark Chocolate & Peanut bar contains peanuts and soy and carries may-contain warnings for milk and tree nuts.
Keep the current label with each product and check the exact variety before including it in a shared-office order.
-
Ordering from an older product description
A range name or previous listing cannot establish the ingredients, portion or pack count of the item being ordered now.
Check the live listing and current pack for the exact variety and size before placing a recurring order.
Brand references for office snack bars
TREK
TREK distinguishes its High Protein Bars from its standard Protein Flapjacks.
- TREK states that its High Protein Bars provide 15g plant-based protein per bar.
- Ocado lists 9g protein and 227 kcal for the standard Cocoa Oat Protein Flapjack, below the UK 20%-of-energy high-protein threshold. Check the exact High Protein flavour’s full pack panel before comparing other nutrients or allergens.
Nature Valley
Its Protein Peanut & Chocolate bar provides a named 40g portion with a published UK nutrition panel.
- Nature Valley lists 10.2g protein and 196 kcal per bar; protein supplies about 20.8% of its energy, meeting the UK high-protein criterion.
- This variety contains peanuts, soy and milk and may contain tree nuts, so check its label before sharing.
Eat Natural
Its Dark Chocolate & Peanut bar is a nut-based option with a published per-bar nutrition panel.
- Eat Natural lists 7.8g protein per 40g Dark Chocolate & Peanut bar.
- At 220 kcal per bar, that protein supplies about 14.2% of its energy, below the UK high-protein threshold. The product contains peanuts and soy and has may-contain warnings for milk and tree nuts.
nākd.
Its Peanut Butter Protein bar is a fruit-and-nut choice described as vegan and no added sugar.
- Tesco lists 7.6g protein per 45g bar.
- Tesco also lists 189 kcal and 13g sugars per bar; protein supplies about 16.1% of its energy, below the UK high-protein threshold. Check the peanut and may-contain declarations on the pack.
Graze
Graze describes plant protein, fibre and vitamins or minerals as attributes across its wider snack range.
- Its range offers different snack formats to consider for an office assortment.
- For a high-protein requirement, assess a named bar’s current claim and nutrition panel rather than applying a range-wide description to it.
Alpen
Alpen is a familiar cereal-bar reference, but a past range name is not enough to choose a current high-protein bar.
- Check a current listing and the exact pack’s protein and energy figures before including an Alpen bar in a high-protein order.

Common questions
Does 7g or 9g of protein make a bar “high protein”?
Not necessarily. UK nutrition-claim rules require at least 20% of the food’s energy to come from protein. Compare protein and kcal for the same bar, using protein grams × 4 kcal divided by total kcal, or check its current high-protein claim and panel.
How does Nature Valley Protein Peanut & Chocolate meet that criterion?
Nature Valley lists 10.2g protein and 196 kcal per 40g bar, so protein supplies about 20.8% of its energy. It contains peanuts, soy and milk and may contain tree nuts; check the current pack before sharing it.
Can I choose an office assortment without checking every bar’s allergens?
Check each exact product. Food Standards Agency guidance says allergen information must be provided for prepacked foods, and ingredients and may-contain statements differ between bars. Keep that information available to colleagues choosing a snack.
Are vegan or no-added-sugar bars automatically high protein?
No. Those descriptions address different attributes. Tesco lists 7.6g protein and 189 kcal for a 45g nākd Peanut Butter Protein bar, putting protein at about 16.1% of its energy—below the UK high-protein threshold.
