Workers needing a portable lunch stopgap
If a bar needs to fit in your bag or desk drawer, compare the protein stated per bar and decide what else you will have for lunch. Portability does not make a snack a complete meal.
Who is choosing a bar?
Plant-based shoppers
Look for a vegan-labelled product that also meets your ingredient requirements. Barebells Vegan Fudge Brownie, for example, contains wheat and soy and carries precautionary allergen statements.
Shoppers checking sugar and allergens
Read the sugar figure, ingredients and allergy advice for the exact flavour. A sugar claim on the front of a pack does not replace checks for milk, soy, wheat or precautionary nut statements.
What matters when choosing?
Start with the declared serving, then check dietary compatibility and whether you need other food alongside the bar.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per bar | Compare grams of protein for the exact flavour and bar size. Grenade UK declares 21g for its OREO bar; Myprotein UK lists 16g per 60g Salted Caramel Breakfast Layered Bar. | I want to know what one bar contributes, rather than relying on a range-wide claim. |
| Lunch plans | Consider what else you will eat that day. The NHS Eatwell Guide describes balance across food groups over a day or week, not a requirement for every meal to contain every group. | If the bar is my lunch stopgap, I may want fruit, vegetables or another food alongside it when practical. |
| Sugar and sweeteners | Read sugars per bar on the selected flavour’s panel and check its sweeteners and consumption warnings. Grenade UK warns that excessive consumption of its OREO bar may cause a laxative effect. | When sugar is a deciding factor for me, I still want to understand the ingredients and warnings. |
| Dietary fit | Check the exact ingredients and ‘may contain’ statement. Barebells UK lists wheat and soy in Vegan Fudge Brownie and warns that it may contain milk, peanuts, tree nuts and sesame. | A vegan label matters to me, but I also need to check allergens separately. |
| Pack format | Confirm the number of bars and size of each serving. Tesco Groceries lists both individual Barebells bars and Grenade multipacks; check the current pack label before buying. | I may prefer to try an individual bar before choosing a multipack. |
Checks that are easy to miss

Assuming protein makes a bar a complete lunch
A protein figure does not show whether the bar supplies the range of foods you want across your day.
Use it as a portable component or stopgap. The NHS Eatwell Guide considers food-group balance over a day or week, so think about what else you will eat.

Reading ‘vegan’ as ‘allergen-free’
Barebells UK lists wheat and soy in its Vegan Fudge Brownie bar, with precautionary statements for other allergens.
Check the ingredients and ‘may contain’ wording on the exact pack, including when buying a familiar flavour again.
-
Buying a multipack before checking warnings
Grenade UK and Barebells UK warn that excessive consumption of certain bars may cause a laxative effect, a practical consideration when carrying bars for work or travel.
Read the chosen product’s warning and consider trying an individual bar before committing to a multipack.
-
Comparing different flavours as though they were identical
Bar sizes and declared nutrition differ between the named products, while Myprotein UK notes that nutrition can vary by flavour.
Compare the exact flavour, serving size, protein, fibre, sugars and allergen statement rather than applying one bar’s figures to a whole range.

Common questions
Can a protein bar replace lunch?
Not automatically: a bar’s protein figure does not establish that it covers everything you want from lunch. The NHS Eatwell Guide considers dietary balance over a day or week, so a bar can be a portable component or stopgap alongside other foods when practical.
How should I compare protein amounts?
Compare the declared protein for the exact bar and serving size. Grenade UK lists 21g for its OREO bar, Myprotein UK lists 16g per 60g Salted Caramel Breakfast Layered Bar, and Barebells UK lists 15g per 55g Vegan Fudge Brownie bar; those figures do not apply to every flavour in each range.
Does vegan mean gluten-free or allergen-free?
No. Barebells UK states that its Vegan Fudge Brownie contains wheat and soy and may contain milk, peanuts, tree nuts and sesame. Read the exact pack’s ingredients and precautionary allergen statement.
Why check a bar’s sweeteners and warnings?
The warning can matter if you plan to eat several bars: Grenade UK’s OREO bar and Barebells UK’s Vegan Fudge Brownie warn that excessive consumption may cause a laxative effect. Follow the wording on the product you choose.
Should I use an online nutrition panel or the pack?
Check the pack you are buying. Tesco Groceries cautions that formulations, nutrition, dietary and allergen information can change, so an online listing should not replace the current product label.
