Among the four bars compared here, Nature Valley Protein Salted Caramel Nut meets Great Britain’s threshold for a high-protein claim: its declared 10.4g protein and 198 kcal per 40g bar put protein at about 21% of its energy, above the 20% threshold published on legislation.gov.uk. The reviewed TREK, Eat Natural and nākd. bars fall below that threshold on their declared figures, but their recipes and dietary suitability may matter more to some shoppers. For a budget shop, compare the number of bars and the nutrition per bar rather than treating every pack labelled “protein” as equivalent.
If the claim matters more than a protein-themed name, compare protein and energy on the same serving basis. Of the four bars compared here, Nature Valley Protein Salted Caramel Nut reaches Great Britain’s 20%-of-energy threshold on its declared nutrition.
Check the number and size of bars alongside protein per bar. A larger pack does not tell you how much protein each snack provides, and bars with similar protein grams can differ in the share of energy supplied by protein.
TREK Original Oat and nākd. Cocoa Hazelnut are described as vegan and gluten-free, but their ingredients and precautionary allergen statements differ. Read the label for the exact flavour and pack if nuts, soya or milk are relevant to you.
Start with what you mean by “high protein”, then compare servings, dietary information and pack formats for the bars you would actually choose.
| Priority | What to check | Your needs |
|---|---|---|
| High-protein claim | Compare protein grams and kcal for the same bar. Protein grams multiplied by 4 kcal, divided by the bar’s total kcal, gives its approximate share of energy from protein. The threshold for a high-protein claim in Great Britain is at least 20%, according to the annex published on legislation.gov.uk. | I want a bar that meets the high-protein threshold, not just one with “protein” in its name. Nature Valley UK declares 10.4g protein and 198 kcal for its 40g Salted Caramel Nut bar, which works out at about 21%. |
| Pack and serving size | Check the number of bars, grams per bar and declared protein per bar. Keep comparisons on a per-bar basis when the bars are different sizes. | I’m choosing snacks for several days and want to know what each bar provides, rather than judging by the size of the outer pack. |
| Diet and allergens | Check vegan or gluten-free wording for the exact product, followed by its ingredients and may-contain statement. Do not assume another flavour has the same recipe. | A plant-based or gluten-free bar still needs to fit my ingredient and allergen requirements. The reviewed TREK, nākd. and Eat Natural products have different nut, soya and milk warnings. |
| Whole-bar nutrition | Read protein, fibre, sugars and kcal together, using the stated serving size. Compare per 100g figures separately if you need a like-for-like measure across different bar sizes. | I’d rather compare the whole snack than choose on protein grams alone. Tesco Groceries lists 7.2g protein, 7.2g fibre and 191 kcal per 45g nākd. Cocoa Hazelnut bar; Nature Valley UK lists 10.4g protein and 198 kcal per 40g Salted Caramel Nut bar. |
Protein grams alone do not establish whether a bar reaches Great Britain’s high-protein threshold. Using the declared servings for the four compared bars, Nature Valley Protein Salted Caramel Nut reaches about 21% of energy from protein; TREK Original Oat, Eat Natural Maple Syrup, Pecans & Peanuts and nākd. Cocoa Hazelnut each fall below 20%.
When that distinction matters, use protein and kcal from the same nutrition serving and compare the result with the 20% threshold published on legislation.gov.uk.
The bar you receive may have a different recipe or label from information saved earlier. Tesco Groceries advises shoppers to read the product label because food products can be reformulated.
Use listings to narrow your choices, then check the current pack’s ingredients, nutrition table and allergen statement.
The reviewed vegan or gluten-free bars can contain peanuts or tree nuts, and some carry may-contain statements for other ingredients. Those details differ between products.
Read the named ingredients and precautionary statements on the exact bar you intend to buy; do not rely on a claim made for a different flavour.
These examples refer to specific bars and product lines, not every snack sold under each brand.
