People packing a sweet snack with lunch
A portioned bar can go alongside the bread, cheese and other parts of a ploughman's lunch. Check the protein and sugars per bar, as well as its ingredients, rather than choosing by the front of the pack alone.
Who is this for?
People choosing plant-based food
Look for an explicit vegan suitability statement. Myprotein labels its Vegan Carb Crusher suitable for vegans and vegetarians; its wheat, soya and precautionary allergen information still matters when choosing for a particular eater.
People checking food allergens
Choose by the exact flavour's ingredient list and precautionary allergen statement. Protein bars in these ranges contain, or carry warnings about, ingredients including milk, soya, wheat, peanuts and nuts; a range-wide description is not a substitute for the pack label.
What should you check?
Start with the eater's dietary requirements, then compare individual bars and pack formats that fit how often you prepare lunch.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per bar | Read protein per serving and the weight of one bar. Tesco lists 21g protein for a 60g Grenade Chocolate Chip Salted Caramel bar; Myprotein lists 16g for a 60g Vegan Carb Crusher serving. | I want to know what one bar contributes to my lunch, rather than compare claims printed on differently sized packs. |
| Flavour and texture | Check the exact flavour and whether the bar is described as soft, layered or another texture. Consider a smaller pack or selection box before committing to one flavour. | A sweet bar after a savoury lunch sounds appealing, but I would rather try the texture before buying a large box. |
| Ingredients and allergens | Read the exact variant's ingredients, vegan statement where relevant, and any 'may contain' warning. Vegan suitability does not establish suitability for a wheat, soya, peanut or nut allergy. | The bar needs to fit the person who will eat it, especially if I am packing or sharing lunch for someone with dietary restrictions. |
| Portions and pack size | Check the number of bars, weight per bar and whether each portion is wrapped for packing. Check the current product listing for the format you intend to order. | I want a pack that matches how many lunches I prepare, without assuming every box contains the same number or mix of bars. |
Common packing mistakes
-
Comparing only the 'high protein' wording
Bars can have different serving weights and nutrition values. Tesco lists 21g protein per 60g for Grenade Chocolate Chip Salted Caramel, while Myprotein lists 16g per 60g for Vegan Carb Crusher; the two also serve different dietary preferences.
Compare the nutrition table per bar and check the flavour and portion weight before choosing a pack.
-
Assuming vegan means allergen-free
Myprotein's Vegan Carb Crusher contains wheat and soya and carries precautionary warnings for other allergens. The Food Standards Agency explains that 'may contain' labelling communicates a risk of unintended allergen presence through cross-contamination.
Read the current label for the precise flavour, particularly when packing lunch for someone with an allergy.
-
Forgetting the perishable parts of lunch
A bar does not change how cheese, cold meat or other perishable lunch items need to be stored. Safefood advises keeping foods that go off quickly cold and using an insulated box or bag for packed lunches.
Plan how the perishable food will stay cold until it is eaten.
An insulated lunch bag and ice pack add things to carry when refrigeration is not available.
-
Committing to a large box before trying a flavour
Bars are offered in different flavours and textures, and a selection box need not have one uniform nutrition or allergen profile.
Try a smaller pack or a selection box if flavour is uncertain, and check each included bar's label before sharing it.
Brand and retailer references
These ranges illustrate different pack and dietary routes; their inclusion does not mean every flavour is suitable for every lunch.
Grenade
Tesco lists Grenade Carb Killa Chocolate Chip Salted Caramel as a single 60g bar and in a 4 x 60g pack.
- Tesco lists 21g protein and 1.3g sugars per 60g serving for that flavour.
- That flavour contains milk and soya and has precautionary allergen information; check its current pack label.
PhD
PhD sells Smart Bar in a 12-pack format that may suit repeated packed lunches.
- PhD's featured Smart Bar page states 21g protein and 1g sugar for the product shown there.
- Check the selected flavour's own nutrition and allergen panel rather than applying those figures to the whole range.
Myprotein
Myprotein lists standard bars, variety boxes and a Vegan Carb Crusher option.
- Its Vegan Carb Crusher is labelled suitable for vegans and vegetarians, with 16g protein and 10g fibre per 60g serving.
- That product contains wheat and soya and carries precautionary allergen warnings, so check its label for the intended eater.
Barebells
Barebells lists Original, Soft and Vegan bars, as well as a selection box for trying different flavours.
- The selection-box format offers a way to try more than one flavour.
- Nutrition and allergen information varies by product; check each bar in a mixed pack individually.
Quest
Quest bars are listed as singles and mixed boxes by the UK retailer The Protein Pick and Mix.
- Singles offer a way to try a flavour before choosing a box.
- Use the exact UK product's nutrition, ingredients and allergen label rather than applying Quest's general range description to every flavour.
Tesco
Tesco is a grocery retailer, not a protein-bar manufacturer. Its listings include Grenade multipacks and Barebells single bars.
- A grocery listing lets you check a bar alongside other items for a ploughman's lunch.
- Check the current listing and exact product label for the format and flavour you want.

Questions about protein bars at lunch
Should a protein bar replace the rest of a ploughman's lunch?
Treat a bar as an optional sweet snack alongside the other lunch items, not as a reason to leave out the bread, cheese or produce. Check its portion and ingredients in the context of the lunch you are actually packing.
Does the whole lunch need to be kept cold because it contains a bar?
Plan cold storage around the perishable food, not the bar alone. Safefood advises keeping foods that go off quickly cold and using an insulated box or bag for packed lunches; follow the storage instructions on the particular bar as well.
Is a vegan protein bar suitable for someone with a nut or soya allergy?
Not necessarily. Myprotein's Vegan Carb Crusher contains soya and carries peanut and nut precautionary warnings; check the current label of the exact bar against the eater's requirements.
What does 'may contain' mean on a bar?
The Food Standards Agency explains that precautionary allergen labelling signals that a regulated allergen could be unintentionally present through cross-contamination. Check both the ingredients and that statement on the exact product rather than relying on a general claim about its range.
Is the protein claim enough to compare two multipacks?
No. Compare protein per individual bar alongside bar weight, sugars, ingredients, allergens and the number of portions. For example, Tesco lists 21g protein per 60g Grenade Chocolate Chip Salted Caramel bar, while Myprotein lists 16g per 60g Vegan Carb Crusher serving; those figures describe those specific products, not every bar in either range.
