People comparing fat content
If limiting fat is the reason for changing bars, start with total fat per 100g. A ‘less sugar’ or ‘no added sugar’ label answers a different question.
Who is choosing an office snack bar?
People packing a small break snack
A bar eaten alongside lunch has a different role from a larger between-meal snack. Check both the pack’s portion size and its per-bar nutrition.
People checking dietary exclusions
For vegan, gluten-free or allergen-related needs, read the ingredient and ‘may contain’ statements on the exact pack, particularly before bringing bars into a shared office.
What should you compare?
Start with the fat figure that lets you compare different-sized bars, then look at the portion you would actually pack and any ingredient restrictions.
| Priority | What to check | Your needs |
|---|---|---|
| Fat claim | Compare total fat per 100g. For solid foods, legislation.gov.uk permits a ‘low fat’ claim only at no more than 3g per 100g. If a pack says ‘reduced fat’, check what similar product it is compared with. | I want the fat claim to match the nutrition panel, rather than relying on ‘less sugar’, ‘high protein’ or a small-looking bar. |
| Portion | Check the bar’s weight and per-bar nutrition after comparing per 100g. The named examples include 23g, 35g, 40g and 50g bars, according to their Joybuy UK, Tesco Groceries, Nature Valley UK and Snackfully listings. | A small bar may be enough alongside my packed lunch; for a larger snack, I want to see what the whole bar contains. |
| Other nutrients | Read fat, saturates, sugars and salt separately; GOV.UK says front-of-pack traffic-light labels show these measures when used. Check protein or fibre per bar if either matters to your choice. | I may want a protein or fruit-and-nut bar, but I do not want that description to stand in for a fat comparison. |
| Ingredients | Read the current ingredient and allergen statement, including ‘may contain’ wording. Check any vegan, dairy-free or gluten-free label on the exact product. | Before packing or sharing a bar at work, I need to know whether its ingredients conflict with a dietary restriction or workplace allergy policy. |
What can mislead your choice?
-
Reading ‘no added sugar’ as ‘low fat’
The claims describe different nutrients. Tesco Groceries lists Nakd Blueberry Muffin at 3.9g fat per 35g bar despite its no-added-sugar label.
If fat is your priority, compare total fat per 100g and check the basis of any ‘reduced fat’ wording.
-
Comparing only the front of the pack
A 23g oat bar and a 50g flapjack are different-sized portions, so per-bar figures alone do not give a like-for-like fat comparison.
Compare nutrition per 100g first, then use the per-bar figures to judge the portion going into your lunch.
-
Overlooking allergens in a shared office
Named fruit-and-nut and protein bars include nuts or peanuts, and some carry further precautionary allergen statements.
Check the exact pack’s ingredients and ‘may contain’ wording before buying or sharing it, and follow any workplace allergy policy.
-
Using an old ‘Light’ bar listing
Alpen Muesli lists Alpen Light Bars Chocolate & Orange among products it no longer makes.
Check that the particular bar is a current product and read its current nutrition panel before considering it for a reduced-fat lunch.
Brand references worth checking
Nature Valley
Its named oat and protein bars show why the type of bar matters as much as the brand.
- Joybuy UK lists Oaty & Crispy Honey as 5 x 23g bars with 8.0g fat per 100g.
- Nature Valley UK lists Protein Salted Caramel Nut at 29.5g fat per 100g. Neither figure meets the 3g-per-100g condition for a ‘low fat’ solid food claim set out by legislation.gov.uk.
Nakd
Blueberry Muffin is a 35g fruit-and-nut bar labelled vegan, gluten free and dairy free in its Tesco Groceries listing.
- The same listing gives 3.9g fat and 17g sugars per bar, making both figures available for a portion-level check.
- It contains cashews and almonds; check the current pack for its full allergen statement. Its dietary labels do not establish a low-fat claim.
Graze
Graze describes its Oat Boost range in terms of oats and reduced sugar.
- That positioning may be relevant if you are comparing oat-based snacks.
- A sugar claim does not establish the total fat in a particular bar; compare the current pack’s per-100g panel before making a reduced-fat choice.
Trek
Original Oat Protein Flapjack is a 50g option for someone considering a larger snack.
- Snackfully lists 10.2g protein per 50g bar.
- The same listing gives 9.8g fat per bar; compare that portion with smaller bars rather than treating ‘protein’ as a fat claim.
Eat Natural
Its named peanut-and-chocolate protein bar illustrates the different priorities involved in choosing a nut-led snack.
- Eat Natural UK lists 7.8g protein and 2.4g fibre per 40g Dark Chocolate & Peanut Protein Bar.
- It also lists 14.5g fat per bar and states that the product contains peanuts and soya.
Alpen
An older ‘Light’ product name is not enough to select a current bar.
- Alpen Muesli lists Alpen Light Bars Chocolate & Orange among products no longer made. Check any current Alpen bar’s listing and nutrition panel on its own terms.

Nakd Blueberry Muffin Fruit & Nut Bars, 4 x 35g
This 35g fruit-and-nut bar offers a different lunchbox option if its ingredients suit you. Tesco Groceries lists 3.9g fat and 17g sugars per bar and labels it vegan, gluten free and dairy free. It contains cashews and almonds; check the current pack for other allergen statements.

Special K Dark Chocolate Snack Bars, 6 x 21.5g
The 21.5g portion may suit a short office break alongside a packed lunch. Compare the current pack’s per-100g fat figure with other bars; its portion size alone does not establish a low-fat claim.

Cadbury Brunch Light Orange Cereal Bars, 4pk 104g
This four-pack is another portioned cereal-bar option for an office lunch. ‘Light’ is part of the product name; check the current nutrition panel and any claim wording rather than assuming it means low fat.
Office snack bar questions
Does ‘reduced sugar’ mean a snack bar is reduced fat?
No. Sugar and fat are separate figures on the nutrition panel. Compare total fat per 100g, and check the comparison behind any ‘reduced fat’ wording; for a ‘low fat’ claim on a solid food, legislation.gov.uk sets a maximum of 3g fat per 100g.
How do I compare bars of different sizes?
Use the per-100g nutrition for a like-for-like comparison, then read the per-bar figures for the portion you will pack. The named examples range from a 23g Nature Valley oat bar listed by Joybuy UK to a 50g Trek flapjack listed by Snackfully.
What should I check before sharing bars at work?
Read the exact pack’s ingredient and allergen statement, including any ‘may contain’ wording, and follow your workplace’s allergy policy. GOV.UK guidance identifies ingredients and allergens as part of the information required on pre-packed food labels.
Can I rely on a product page when checking allergens?
Use the current pack for the final check, even if a product page helped you make a shortlist. Pay particular attention to the ingredient list and precautionary statements for nuts, peanuts, soya, milk and gluten-containing cereals where relevant.
