For a ploughman’s lunch where protein per bar is the priority, Nature Valley Peanut & Chocolate lists 10.2g in a 40g bar; TREK Cocoa Oat offers a vegan, gluten-free alternative with 9g in a 50g flapjack. Compare the figures for the individual bar and check its allergens, then keep any cheese, cooked meat or other chilled lunch foods cold separately.
If you are adding a bar to bread, cheese, pickle or other lunch components, compare protein per individual bar rather than relying on the word “protein” in its name. Pack size and bar size can otherwise make figures difficult to compare.
A dietary label needs to apply to the exact bar you choose. TREK Cocoa Oat and nākd. Cocoa Hazelnut are described as vegan and gluten free, but their ingredients and allergen statements still need checking.
Peanuts, other nuts, soy and milk appear in the ingredients or precautionary statements of several bars discussed here. Check each wrapper before packing a bar for someone else or taking it into a shared lunch setting.
Start with the amount in one bar, then check whether its dietary information and storage instructions fit the rest of the lunch.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per bar | Compare protein and energy for one bar, not just per 100g or per multipack. Nature Valley lists 10.2g protein per 40g Peanut & Chocolate bar; TREK lists 9g per 50g Cocoa Oat flapjack. | I want to know what the bar adds to my lunch without assuming that every product named “protein” has the same nutritional profile. |
| Dietary suitability | Read vegan, gluten-free and dairy-free statements for the exact flavour and pack. Check the ingredients as well as any may-contain statement. | For a vegan or gluten-free lunch, I need the claim on the bar I will actually pack, not an assumption about its brand. |
| Whole-bar nutrition | Use the per-bar figures for sugars, saturated fat and kcal. A “no added sugar” statement does not give the total sugars figure: the UK retailer listing for nākd. Cocoa Hazelnut states 13g sugars per 45g bar. | If the bar is an addition to lunch, I want to compare the portion I will eat rather than judge it by one front-of-pack phrase. |
| Lunch storage | Follow the bar’s storage instructions and check use-by dates and storage directions on chilled foods separately. GOV.UK food-business guidance distinguishes chilled-food temperature control from ambient storage. | A wrapped bar may be convenient to carry, but I still need to keep cheese, cooked meat, eggs or prepared salad cold when their instructions require it. |
A product name does not tell you how much protein you will get from the individual bar or how that figure relates to its energy.
Read the protein and kcal figures for the serving you will pack. If a high-protein claim matters to your choice, check its basis rather than relying on the name.
The UK retailer listing for nākd. Cocoa Hazelnut describes it as having no added sugar while listing 13g sugars per 45g bar.
Check sugars, saturated fat and kcal per bar, then consider how the portion fits alongside the rest of the lunch.
Bars in these ranges have different ingredients, and an ingredient list does not replace a may-contain statement. Nature Valley Peanut & Chocolate, for example, contains peanuts, soy and milk and may contain tree nuts.
Read the exact wrapper each time, particularly when packing food for someone with an allergy requirement.
Keeping a wrapped bar in a cool, dry place does not establish safe storage conditions for cheese, cooked meat, eggs or prepared salad packed beside it.
Pack the bar separately and follow the chilled foods’ own storage and use-by instructions; provide cold storage where those foods require it.

A peanut-and-chocolate bar for a nut-led addition to lunch, supplied as three 40g bars. Check this pack’s ingredients, allergens and nutrition before applying figures from another Eat Natural listing or recipe.
Check protein and energy for the individual bar rather than deciding from its name. A high-protein claim concerns the proportion of energy supplied by protein, as set out in legislation.gov.uk’s published criterion, so protein grams alone do not settle that question.
Treat the bar as an addition when planning this lunch, not as a reason to ignore the other foods. The NHS Eatwell Guide describes balancing food groups over a day or week rather than requiring every meal to provide that balance on its own.
TREK Cocoa Oat is described as vegan and gluten free, while the UK retailer listing for nākd. Cocoa Hazelnut describes it as vegan, gluten free and dairy free. Check the exact wrapper as well: TREK Cocoa Oat contains soy and may contain peanuts, nuts and milk; nākd. Cocoa Hazelnut contains peanuts and hazelnuts and may contain soy and other nuts.
Follow the bar’s storage instructions, but manage cheese, cooked meat and other foods requiring refrigeration separately. Check their storage and use-by instructions and provide suitable cold storage; an ambient bar does not change those requirements.
Check the physical pack before buying or eating, especially when an allergen or dietary statement matters. Nature Valley advises checking pack information because products may be reformulated, and the same precaution helps when comparing different flavours or listings.
