Households choosing a packaged after-school snack
If a wrapped bar is convenient, compare its full nutrition panel and serving size. A protein figure alone does not describe its sugars, fibre or energy.
Who is this for?
Families looking for plant-based options
TREK describes its bars as plant-based, while the nākd. Peanut Butter Protein Bar is listed as vegan and dairy-free by Holland & Barrett. Check the exact flavour and pack for dietary and allergen information.
Households checking for food allergens
The Nature Valley, Eat Natural and nākd. flavours discussed here contain peanuts, and their ingredient or precautionary statements also name other allergens. Check the bar that will actually be served before choosing it for someone with an allergy.
What should you check?
Start with the serving you would offer, then check the rest of that flavour’s label before deciding whether it suits the household.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per bar | Read the protein amount and serving weight for the exact flavour. Nature Valley UK lists 10.2g per 40g Peanut & Chocolate bar; Eat Natural UK lists 7.8g per 40g Dark Chocolate & Peanut bar; Holland & Barrett lists 7.6g per 45g nākd. Peanut Butter Protein Bar. | I want to know what one bar provides, rather than rely on a figure for a product range or a different-sized serving. |
| Full nutrition panel | Compare sugars, fibre and energy per bar alongside protein. Check front-of-pack traffic-light information where provided; the NHS recommends looking at the nutrition label when choosing packaged snacks for children. | A protein bar still needs to fit the snack portion I plan to offer. I want to compare the figures for the flavour I will buy, not assume its protein claim tells the whole story. |
| Allergens | Read the ingredients and precautionary statements on the exact pack, including after a flavour change. The Food Standards Agency says specified allergens must be emphasised in the ingredients list of pre-packed food. | Before comparing nutrition or flavour, I need to rule out ingredients and precautionary warnings relevant to the person eating it. |
| Dietary claims | Check vegan, dairy-free or gluten-free wording against the exact product. These claims do not replace an allergen check: the nākd. Peanut Butter Protein Bar listed by Holland & Barrett contains peanuts. | If I need a plant-based or gluten-free bar, I still want to check whether its ingredients and allergen warnings suit our household. |
Common buying mistakes
-
Choosing by the protein claim alone
The compared flavours have different serving weights and different amounts of sugars, fibre and energy as well as protein.
Use the nutrition panel for the individual bar you intend to serve, and compare the figures together.
-
Reading “no added sugar” as “low sugar”
Holland & Barrett lists the nākd. Peanut Butter Protein Bar as having no added sugar, but its nutrition panel gives 13g sugars per 45g bar.
Read the “of which sugars” figure for the serving, even when the front of the pack says no added sugar.
-
Using a dietary claim as an allergen check
A vegan or gluten-free claim does not establish that a bar is suitable for a nut allergy. The listed nākd. Peanut Butter Protein Bar contains peanuts and may contain other nuts.
Check the delivered pack’s ingredients and precautionary statements for the exact flavour before serving it.
-
Making packaged bars the routine snack without comparison
The NHS recommends fruit and vegetables as snacks for children and advises aiming for no more than two packaged snacks a day.
Keep other snack choices in the routine and use the label to decide when a packaged bar fits.
Brand and product-line references
These examples describe specific flavours or product lines; their figures and dietary statements should not be applied to every bar from the same brand.
Nature Valley
Nature Valley UK lists protein bars, including its Peanut & Chocolate flavour.
- The Peanut & Chocolate nutrition panel gives 10.2g protein, 4.4g fibre and 6.9g sugars per 40g bar.
- That flavour contains peanuts, soya and milk and may contain tree nuts; check the delivered pack for the current recipe.
TREK
TREK describes its bars as plant-based and distinguishes Protein Flapjacks from its High Protein Bar line.
- TREK states 9g plant protein for its Protein Flapjacks and 15g for its High Protein Bars; these are different product lines.
- Check the individual flavour’s nutrition, ingredients and allergen information rather than applying a product-line statement to a particular pack.
Eat Natural
Eat Natural UK has a protein fruit-and-nut bar range that includes Dark Chocolate & Peanut.
- The Dark Chocolate & Peanut panel lists 7.8g protein and 2.4g fibre per 40g bar.
- That flavour contains peanuts and soya and may contain milk and tree nuts. Its figures do not describe other Eat Natural bars.
nākd.
Holland & Barrett lists the Peanut Butter Protein Bar as a vegan, dairy-free and gluten-free fruit-and-nut option.
- The listed 45g bar provides 7.6g protein and 6.8g fibre.
- It contains peanuts, may contain soya and other nuts, and lists 13g sugars per bar despite its no-added-sugar description.
Graze
Graze offers snacks and Oat Boost flapjacks, which shoppers may encounter alongside protein bars.
- Graze describes plant protein and fibre among the attributes of its wider snack range.
- Compare the nutrition panel of a particular Graze bar before treating it as a high-protein option; a range-wide description does not give its protein per serving.

Questions about after-school snack bars
Does a protein claim tell me whether a bar suits an after-school snack?
No. Read the exact bar’s protein, sugars, fibre, energy, ingredients and allergens together. The NHS advises checking nutrition labels for packaged children’s snacks and recommends fruit and vegetables as snack choices.
Can a no-added-sugar bar still contain sugars?
Yes. Holland & Barrett lists the nākd. Peanut Butter Protein Bar as having no added sugar, while its nutrition panel gives 13g sugars per 45g bar. Check the sugars figure for the portion you intend to serve.
Is a vegan or gluten-free protein bar suitable for someone with a nut allergy?
Not on the strength of those claims alone. The nākd. Peanut Butter Protein Bar is listed as vegan and gluten-free but contains peanuts and may contain other nuts. Read the exact pack’s ingredients and precautionary statements.
How should I check allergens when buying a different flavour?
Check the ingredients and precautionary information on that flavour’s delivered pack before serving it. The Food Standards Agency says specified allergens must be emphasised in the ingredients list of pre-packed food; do not carry an allergen check over from another flavour.
