Shoppers comparing smaller portions
If you want an individually portioned sweet snack for Bonfire Night, compare kcal per whole bar. Check per-100g figures separately when bars differ in size.
Who is this for?
Shoppers comparing protein and fibre
If protein or fibre matters to your snack choice, read those figures alongside calories for the whole bar. A protein claim alone does not tell you its calorie count.
Hosts buying for a mixed group
Check each flavour’s current ingredients and allergen information before sharing. Fruit, oat and protein bars can have different ingredients and cross-contact warnings.
What should you compare?
Start with the whole-bar serving, then compare nutrition and ingredients against the needs of the people who will eat it.
| Priority | What to check | Your needs |
|---|---|---|
| Portion calories | Check kcal per bar and whether the stated serving is one whole bar. Use per-100g values to compare bars of different weights. | I want to know the calories in the portion I will eat, rather than judge a bar by its pack size or front-of-pack wording. |
| Protein, fibre and sugars | Read grams per bar on the same basis as calories. Check total sugars alongside the ingredients; “no added sugar” does not mean sugar-free. | Protein or fibre might matter more to me than choosing the bar with the fewest calories. I still want to see its total sugars per bar. |
| Allergens | Read the exact flavour’s current ingredients and may-contain statement. Keep individual wrappers available when sharing bars. | Guests may need to check for nuts, soya, milk or other allergens before taking a bar. |
Common buying mistakes
-
Looking only at calories per 100g
The bars in the Tesco Groceries, Body&Fit, Nature Valley UK and Eat Natural UK examples weigh 30g to 40g each. A per-100g figure does not tell you the calories in one bar.
Read kcal per whole bar for the portion, then use per-100g values for a comparison across different bar sizes.
-
Assuming “protein” or “no added sugar” means fewer calories
Nature Valley UK lists 196 kcal for its 40g Protein Peanut & Chocolate bar. Body&Fit lists 13.7g total sugars in a 35g Nakd Cashew Cookie, although Nakd describes its range as having no added sugar.
Compare calories, total sugars, protein and fibre per bar instead of using a single pack claim to make the choice.
-
Assuming one type of bar is suitable for every guest
The product examples include nuts, soya, milk and oats, as well as product-specific may-contain warnings. A vegan or fruit-based description does not settle every allergen question.
Check each current wrapper before sharing and keep the ingredient information with the bars.
-
Using an old Alpen Light comparison
Alpen’s UK FAQ says several former varieties, including Alpen Light Bars Chocolate & Orange and some yoghurt bars, are no longer made. An older comparison may therefore describe a different product from one you can inspect now.
Check the exact current flavour, size and nutrition panel before comparing it with another bar.
Brand references
These examples describe particular bars or ranges, not every product made by each brand.
Graze
Tesco Groceries lists the Honey Oat Boost flapjack as a 30g bar with 129 kcal, 4.9g fibre and 2.3g protein.
- Its 30g serving makes the whole-bar calorie figure straightforward to compare.
- The Honey flavour contains oats, soya and honey; check its wrapper against guests’ dietary needs.
Nature Valley
Nature Valley UK lists 196 kcal, 10.2g protein and 4.4g fibre for its 40g Protein Peanut & Chocolate bar.
- The per-bar figures let shoppers weigh protein and fibre against portion calories.
- This flavour contains peanut, soya and milk and may contain other tree nuts.
Nakd
Body&Fit lists the 35g Cashew Cookie bar at 155 kcal and 13.7g total sugars; its listed ingredients are cashews and dates.
- Nakd describes its fruit-and-nut range as vegan and made without added sugar.
- Cashew Cookie contains nuts, and “no added sugar” does not mean the bar contains no sugars.
Eat Natural
Tesco Groceries lists 198 kcal and 10.4g protein for the 40g Peanuts, Almonds & Salted Caramel bar. Eat Natural UK lists 220 kcal and 7.8g protein for its 40g Dark Chocolate & Peanut bar.
- These figures offer two distinct nut-based protein-bar examples to compare by whole-bar serving.
- Check each flavour’s nut and other allergen declarations; the warnings are product-specific.
Trek
Tesco Groceries describes the Biscoff Protein Flapjack as vegan, with 9g plant protein per bar.
- Its stated protein amount may be relevant if plant-based protein is a selection criterion.
- Check kcal per bar on the current pack before comparing its portion calories with the other examples.
Alpen
Alpen’s UK FAQ identifies several former Light Bar and yoghurt-bar varieties as no longer made.
- If an older Alpen bar appears in a comparison, confirm the exact current product and its nutrition label before using those figures.

Nakd Blueberry Muffin Fruit & Nut Bars, 4 x 35g
A fruit-and-nut option for comparing individual bar portions. Check the Blueberry Muffin pack’s own calories, sugars and nut warnings; figures for Nakd Cashew Cookie describe a different flavour.

Graze Oat Boosts Lemon Blueberry, 4 x 30g
The 30g bar size is relevant when comparing whole-bar portions. Read this flavour’s nutrition and allergen label rather than applying figures from Graze Honey Oat Boost.

Graze Protein Bites Cocoa, Vanilla Oat Squares, 4 x 30g
For these 30g oat squares, compare the exact pack’s calories and protein per square. The product name alone does not establish how much protein a serving contains; check allergen information before sharing.

Graze Oat Boosts Cherry Bakewell, 4 x 30g
Another 30g oat-bar flavour to assess by whole-bar portion. Use the Cherry Bakewell wrapper for its own nutrition, ingredients and allergen warnings.

Grenade Soft Core Double Chocolate Protein Bars, 12 x 50g
Consider this 50g-per-bar pack if protein is part of your selection criteria. Compare its own per-bar calories, protein and allergen label with the smaller oat and fruit-and-nut bars rather than borrowing figures from other protein brands.
Frequently asked questions
How do I compare calories in snack bars of different sizes?
Use kcal per whole bar to compare the portions you would eat, then check per 100g for a like-for-like comparison across sizes. Tesco Groceries lists 129 kcal for a 30g Graze Honey Oat Boost; Eat Natural UK lists 220 kcal for a 40g Dark Chocolate & Peanut Protein Bar. Those figures describe the named products, not their wider ranges.
Does “no added sugar” mean a bar has no sugars or few calories?
No. Nakd says its fruit-and-nut range has no added sugar, while Body&Fit lists 13.7g total sugars and 155 kcal in a 35g Cashew Cookie bar. Read the total-sugars and calorie figures for the exact flavour.
When might a protein bar suit my Bonfire Night plans?
Consider one if its stated protein amount matters to your snack choice, while comparing its whole-bar calories too. Nature Valley UK lists 10.2g protein, 4.4g fibre and 196 kcal for its 40g Protein Peanut & Chocolate bar; it also contains peanut, soya and milk.
What should I check before sharing bars with guests?
Read each flavour’s current ingredients and may-contain statement, and keep its wrapper available. The named examples include different nut, soya, milk and oat ingredients or warnings, so a description such as “fruit bar” or “vegan” cannot replace a product-specific allergen check.
Can I use an older Alpen Light Bar comparison?
Only after checking which product the comparison describes. Alpen’s UK FAQ says several former varieties, including Alpen Light Bars Chocolate & Orange, are no longer made; compare the nutrition panel of the exact current bar you are considering instead.
