Buyers planning smaller portions
If bars will replace or sit alongside biscuits, compare the kcal in one bar as well as its weight. Sugar, saturated fat and allergens still matter when choosing what to put in the tin.
Who is the tin for?
A shared tin has to work for the people choosing from it, not just meet one calorie figure.
Colleagues seeking a more substantial snack
Someone choosing a bar for its protein or fibre may accept a larger portion. Keep those choices distinct from bars selected primarily for fewer kcal per serving.
Offices with dietary or allergen requirements
Colleagues need to identify the ingredients in the exact bar they take. Keep wrappers and outer-pack information accessible, particularly when several flavours share a tin.
What should you compare?
Start with the portion someone will take, then compare nutrition and ingredient information for that same bar.
| Priority | What to check | Your needs |
|---|---|---|
| Portion and calories | Read kcal and weight per bar. Use per-100g values when comparing bars of different sizes, then return to kcal per bar for the portion taken from the tin. | I want a smaller snack without mistaking a lighter bar for a like-for-like nutritional match with a larger one. |
| Sugars and saturated fat | Compare both values per bar alongside kcal. Read any traffic-light labelling and check the ingredient list rather than relying on fruit, protein or fibre wording. | A lower-kcal bar might still have a sugars or saturated-fat value I want to compare with other options. |
| Protein and fibre | Check the grams per bar, its weight and its kcal. Nature Valley UK lists about 10 g protein in its 40 g Protein Peanut & Chocolate bar, which has 196 kcal. | If protein matters more to me than the smallest calorie portion, I can compare protein bars separately from lighter snack options. |
| Ingredients and allergens | Check the exact flavour’s ingredients, allergen information and any precautionary wording. Keep the individual wrapper and outer pack available for reference. | Before taking a bar from a shared tin, I need to know which product it is and be able to read its ingredients. |
Common buying pitfalls
-
Assuming a protein or fibre claim settles the choice
In its November 2025 audit of 458 snack bars at 10 major UK retailers, Action on Salt and Sugar reported that 37% of the products were high in sugars and 55% high in saturated fat under UK front-of-pack thresholds. Those figures describe the audited products, not office buyers’ preferences.
Use a protein or fibre claim to identify an attribute you want, then compare kcal, sugars and saturated fat on the nutrition panel.
-
Comparing kcal without checking bar size
Eat Natural lists 86 kcal for its 25 g Apple Soft Fruit Bar, while TREK lists 227 kcal for its 50 g Cocoa Oat Protein Flapjack. They are different-sized portions serving different snack preferences.
Use kcal per bar to judge the portion taken from the tin and per-100g figures for a size-adjusted comparison.
-
Taking wrappers off bars in a shared tin
Once bars are separated from their packaging, colleagues may struggle to identify the exact flavour or check its ingredients and allergen wording.
Leave bars wrapped, retain the outer pack while the tin is in use and follow any workplace allergy controls when choosing what to include.
-
Ordering from an old product list
Alpen Muesli identifies several former Alpen bar flavours as no longer made. An older list may therefore describe a product that cannot be reordered.
Confirm the exact flavour and pack on a current UK product listing before adding it to a repeat order.
Brand references
These examples illustrate different bar formats; a brand name alone does not establish the nutrition or allergens of every flavour.
Graze
Graze has oat-based snacks relevant to a smaller-portion comparison.
- Tesco lists Graze Cocoa Vanilla Oat Boost at 116 kcal per 30 g bar.
- Graze’s statements about its nutritional thresholds are brand-wide positioning, not a substitute for checking the chosen flavour’s label.
Eat Natural
Its Apple Soft Fruit Bar is a small, individually wrapped fruit-bar example.
- Eat Natural lists 86 kcal per Apple Soft Fruit Bar.
- Check sugars and the nut-related allergen information before choosing this bar for a communal tin.
Nature Valley
Its range includes protein bars as well as other snack-bar formats.
- Nature Valley UK lists about 10 g protein and 196 kcal per 40 g Protein Peanut & Chocolate bar.
- That protein bar is a different portion choice from the cited smaller fruit and oat bars; check its allergens before sharing.
nākd.
The brand offers fruit-and-nut bars and states that its bars contain no added sugar.
- A no-added-sugar description can help identify the formulation someone is looking for.
- It does not establish low total sugars or low calories. Check the exact flavour’s nutrition and allergen information.
TREK
TREK’s protein flapjacks offer a larger-portion route for colleagues prioritising protein.
- TREK lists 9 g protein and 227 kcal per 50 g Cocoa Oat Protein Flapjack.
- Check the exact flapjack’s sugars and precautionary allergen information before placing it in a shared tin.
Alpen
Alpen is a cereal brand whose older bar listings need checking before they inform an office order.
- A specific current bar listing would allow its portion and label to be compared with other products.
- Alpen Muesli says several former bar flavours are no longer made; confirm the exact product before ordering.

Questions about office snack bars
Is the lowest-kcal bar automatically the right one for an office tin?
No. Kcal per bar tells you about the portion someone takes, but sugars, saturated fat and allergens can change which bar suits a shared tin. Eat Natural lists 86 kcal for its Apple Soft Fruit Bar, while Tesco lists 116 kcal for a Graze Cocoa Vanilla Oat Boost; check the remaining label information for each product rather than deciding on those figures alone.
Should a protein bar go in a tin intended for smaller snacks?
It can be a separate option for colleagues prioritising protein, but it should not be treated as the smaller-portion choice on that basis alone. Nature Valley UK lists 196 kcal and about 10 g protein per 40 g Protein Peanut & Chocolate bar; TREK lists 227 kcal and 9 g protein per 50 g Cocoa Oat Protein Flapjack.
Can snack bars be taken out of their wrappers for a shared tin?
Keep them wrapped so colleagues can identify the exact bar and check its ingredients and allergen information. Retain the outer pack as well if it carries information needed to identify the product.
Does 'no added sugar' mean low total sugars?
No. nākd. says its fruit-and-nut bars have no added sugar, but sugars naturally present in fruit still appear in the total sugars figure. Read the nutrition panel for the exact flavour and compare it on the portion you intend to offer.
