Hosts comparing protein per bar
Compare the protein in the portion guests will actually eat, alongside its sugars and energy. Bars carrying protein-focused names do not necessarily provide the same amount per serving.
Who is buying for?
Hosts catering for vegan or gluten-free guests
Check the claim on the exact flavour. TREK describes its Smooth Lemon flapjack as vegan and gluten-free, but its precautionary allergen statement still matters.
Hosts with mixed dietary requirements
Ask guests about relevant restrictions before choosing a shared selection. Nut, soya and milk ingredients or may-contain statements can matter even when a bar is labelled vegan or gluten-free.
What should you check before buying?
Choose the type of bar that fits your guests first, then compare whole-bar nutrition and the current allergen label.
Protein-focused nut bar
Choose when: Protein per bar is the main consideration. Nature Valley UK lists 10.4g per 40g Salted Caramel Nut bar.
Consider: This flavour contains peanuts, almond, soya and milk, so it cannot stand in for a bar chosen around unknown allergy needs.
Vegan oat flapjack
Choose when: A vegan, gluten-free option is needed; TREK states both claims for Smooth Lemon.
Consider: TREK lists a may-contain warning for peanuts, nuts and milk, which guests may need to avoid.
Nut-based protein bar
Choose when: Guests want a peanut-and-chocolate bar and its ingredients suit them. Eat Natural UK lists 7.8g protein per 40g Dark Chocolate & Peanut bar.
Consider: Peanuts account for 49.5% of that recipe; it also contains soya and may contain milk and tree nuts.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per bar | Read grams of protein for one whole bar, not just the product name or a per-100g figure. Compare serving sizes too: Nature Valley UK lists 10.4g per 40g Salted Caramel Nut bar, TREK lists 9g per 50g Cocoa Oat bar, and Eat Natural UK lists 7.8g per 40g Dark Chocolate & Peanut bar. | I want to know how much protein each individually served bar provides. |
| Allergens | Read both the ingredients and any may-contain statement on the exact pack. Check them against guests’ confirmed requirements before putting bars out for sharing. | Guests have different restrictions, so I cannot assume one protein-bar multipack will suit everyone. |
| Portion and sugars | Compare the whole-bar weight, sugars and energy on the same serving basis. Nature Valley UK lists 6.4g sugars and 198 kcal per 40g Salted Caramel Nut bar; TREK lists 14g sugars and 227 kcal per 50g Cocoa Oat bar; Eat Natural UK lists 10g sugars and 220 kcal per 40g Dark Chocolate & Peanut bar. | For a table with several snacks, I want to judge the size and nutrition of one bar rather than its protein figure alone. |
| Dietary claims | Check vegan, vegetarian and gluten-free statements by flavour. Nature Valley UK lists wheat and barley in Protein + Fibre Coconut & Almond; that ingredient list is different from its gluten-free Salted Caramel Nut bar. | If someone needs a gluten-free or vegan choice, I need that claim on the specific bar I am serving. |
Common buying mistakes
-
Treating every “protein” bar as equivalent
The manufacturer figures for the bars discussed here differ, and their stated servings are not all the same size.
Compare protein grams, sugars and energy per whole bar before choosing a party portion.
-
Choosing a shared multipack before asking about allergies
Some of these bars contain peanuts, other nuts, soya or milk, or carry precautionary warnings. Vegan or gluten-free wording does not answer every allergy question.
Confirm guests’ requirements, retain the wrappers for ingredient checks and choose a separately checked alternative where needed.
-
Using a fibre claim as a protein claim
Nature Valley UK lists 7g protein and 5.9g fibre per 36g Protein + Fibre Coconut & Almond bar. Its ingredients also include wheat and barley; neither its fibre figure nor another flavour’s gluten-free claim describes this bar’s gluten status.
Check protein, fibre, sugars and dietary claims separately on the flavour you intend to serve.
-
Relying on an older product description
Nature Valley UK advises checking packs because recipes may change. A previous ingredient list is not enough for a guest who needs to avoid a particular ingredient.
Before buying party quantities, check the current pack’s nutrition panel, ingredients, allergen statements and best-before date.

Questions about party snack bars
What does “high protein” mean on a snack-bar label?
The legislation.gov.uk annex defines the high-protein nutrition claim using protein’s contribution to the food’s energy: at least 20%. For party shopping, also compare the grams of protein in one whole bar; the word “protein” in a product name does not tell you that amount.
Is a vegan protein bar suitable for guests with allergies?
Not automatically. TREK describes its Cocoa Oat and Smooth Lemon flapjacks as vegan, but their product pages carry may-contain warnings for peanuts, nuts and milk. Check the exact pack against each guest’s requirements.
Does gluten-free mean a bar suits everyone at the party?
No. Nature Valley’s gluten-free Salted Caramel Nut bar contains peanuts, almond, soya and milk. Check the complete ingredient list and precautionary statements as well as the gluten-free claim.
Why check the wrapper after reading the product page?
Nature Valley UK says its products may be reformulated and advises checking the pack. The current wrapper is particularly important when a guest needs to avoid a listed ingredient or precautionary allergen.
