People planning individual snacks
Individually wrapped bars make the serving in a shared box easier to identify. Compare the energy and sugars for that bar with the snack you have planned, not just the figures per 100g.
Who is choosing a multi-pack?
Shoppers comparing protein or fibre
A protein or fibre claim may help narrow the options, but bar sizes differ. Check the whole serving alongside the nutrient that interests you.
Households sharing around dietary requirements
Check the current ingredients, allergen statements and dietary markings for every flavour in the exact pack. A claim on one bar does not establish that every variant in a brand’s range has the same recipe.
What should you compare?
Start with the serving you would actually eat. Use the per-100g panel to compare bars of different sizes, then check the per-bar figures and the contents of the multi-pack.
| Priority | What to check | Your needs |
|---|---|---|
| Portion and energy | Check the bar’s weight and kcal per bar. Compare per 100g when bar sizes differ, then use the serving figure for your planned snack. | I want to know what one wrapped bar contributes before choosing a box to use over several days. |
| Sugars and saturated fat | Read sugars and saturated fat per 100g and per bar, alongside the ingredients. NHS guidance identifies more than 22.5g sugars or 5g saturated fat per 100g as high. | A no-added-sugar or wholegrain claim is not enough for me to compare the complete nutrition of two bars. |
| Protein, fibre and size | Compare protein and fibre for the stated serving, then check its weight, kcal and sugars. Do not use a single nutrient claim as a substitute for the full label. | When I choose a protein or fibre bar, I also want to know whether it is the size of the snack I had in mind. |
| Sharing and suitability | Check the number of bars and whether flavours differ. Read each current ingredient list, allergen warning and relevant dietary marking. | Others will share this pack, so each included flavour needs to meet their requirements. |
What is easy to overlook?

Taking a front-of-pack claim as the whole picture
Protein, fibre and wholegrain claims do not describe a bar’s complete nutrition. In its November 2025 audit of 458 snack bars from 10 major retailers, Action on Salt & Sugar classified 37% as high in sugars and 55% as high in saturated fat under UK front-of-pack thresholds.
Compare energy, sugars and saturated fat per bar and per 100g, as well as the protein or fibre you are looking for.
-
Comparing boxes by bar count alone
Bar count does not tell you the serving size: the Sainsbury’s listing for Eat Natural Apple describes 25g bars at 86 kcal each, while Ocado lists 50g TREK variety-pack flapjacks at 224–244 kcal each, depending on flavour.
Choose the serving first; use the number of bars to decide whether the pack suits repeated use or sharing.

Reading “no added sugar” as “low sugar”
Tesco Groceries lists 13g sugars per 45g bar for Nakd Peanut Butter Protein, which is also labelled no added sugar. The wording does not replace the total “of which sugars” figure.
Read that figure for the exact bar and use the ingredients list for context.
-
Assuming every flavour suits everyone sharing
Ingredients and allergen statements matter at variant level. Tesco Groceries lists peanuts in Nakd Peanut Butter Protein and warns that it may contain soya and nuts.
Check the current label for every included flavour before buying or sharing where an allergy or dietary requirement applies.
Brand and range references
These examples show why the exact variant and serving matter more than a brand name; they do not describe every bar in each range.
Graze
Graze offers Oat Boost multi-packs. Tesco Groceries lists the Cocoa Vanilla pack as four 30g bars.
- That Cocoa Vanilla bar lists 116 kcal and 2.7g sugars per bar and is labelled high in fibre and vegan.
- Graze’s lower-sugar comparison is its own comparison with other cereal bars; compare current labels when choosing between exact packs.
Nature Valley
Nature Valley’s UK range includes Crunchy family packs and an eight-bar Protein Peanut & Chocolate big pack.
- Nature Valley lists 10g protein and 4g fibre per bar for the Protein Peanut & Chocolate option.
- Check the exact pack’s current energy, sugars and allergen information before comparing it with other bars.
TREK
Ocado lists a TREK Protein Flapjacks variety pack containing individually wrapped 50g bars in four flavours.
- The listed variety-pack bars provide 9g plant protein per bar and are described as vegan, gluten-free and a source of fibre.
- Listed flavours range from 224 to 244 kcal and 12 to 14g sugars per bar; check the flavour you intend to eat.
Nakd
Nakd makes fruit-and-nut bar multi-packs, including a three-bar Peanut Butter Protein pack listed by Tesco Groceries.
- Each listed 45g Peanut Butter Protein bar provides 7.6g protein and 6.8g fibre.
- It also lists 189 kcal and 13g sugars per bar, contains peanuts and may contain soya and nuts. Its no-added-sugar claim does not mean sugar-free.
Eat Natural
Eat Natural offers fruit-and-nut bar multi-packs. Sainsbury’s lists the Apple Soft Fruit four-pack with individually wrapped 25g bars.
- The listed Apple bar provides 86 kcal per bar and is described as vegan, gluten-free and a source of fibre.
- It also lists 13.8g sugars per bar; its smaller energy serving should not be mistaken for a low-sugar label.
Alpen
Alpen is a familiar cereal-bar name, but the exact product matters when comparing packs.
- Alpen’s product-availability information says several former bar varieties are no longer made. Check the identity and current label of any pack you are considering rather than relying on an older listing.

Graze Oat Boosts Cherry Bakewell 4 × 30g
Another four-pack with 30g bars for a planned oat-bar snack. Check the Cherry Bakewell label itself rather than assuming its nutrition or allergen information matches another Graze flavour.

Nakd Blueberry Muffin Raw Fruit & Nut Bars 4 × 35g
This four-pack has 35g fruit-and-nut bars. If you are comparing it with oat or protein bars, pay particular attention to sugars per bar as well as energy, and check the nut-allergen statement.

Grenade Soft Core Protein Bar Double Chocolate 12 × 50g
Consider this 12-pack when a 50g protein bar is the serving you intend to have. Compare its energy, sugars and protein per bar with smaller options, and check the current ingredients and allergens.

Grenade Soft Core Protein Bar Golden Caramel 12 × 50g
This Golden Caramel option is also a 12-pack of 50g protein bars. Use its own per-bar nutrition and allergen label for the decision; flavour variants should not be treated as nutritionally identical.
Questions about choosing snack bars
Should I compare kcal per bar or per 100g?
Use both: per 100g helps compare differently sized bars, while kcal per bar describes the wrapped serving you plan to eat. NHS label guidance notes that portion figures may be provided as well as per-100g values; check whether the stated portion matches yours.
Does “no added sugar” mean a snack bar is low in sugar?
No. Tesco Groceries lists 13g sugars per 45g bar for Nakd Peanut Butter Protein despite its no-added-sugar label. Compare the “of which sugars” figure on the exact product.
Is a protein bar automatically the better choice for a weight-management snack?
No; compare the complete serving with the snack you have planned. Ocado lists 9g plant protein in each 50g TREK variety-pack flapjack, alongside 224–244 kcal depending on flavour, so the protein figure alone does not settle the choice.
How can I read UK sugar and saturated-fat figures?
Start with the per-100g nutrition panel: NHS guidance describes more than 22.5g sugars per 100g as high in sugars and more than 5g saturated fat per 100g as high in saturated fat. Then check the per-bar figures for the amount you would eat.
Can I rely on one flavour’s dietary and allergen information for a whole multi-pack?
No. Check the current ingredients, allergen statement and dietary markings for each included flavour. For example, Tesco Groceries lists peanuts in Nakd Peanut Butter Protein and warns that it may contain soya and nuts; that information applies to the identified bar, not every Nakd product.
