Desk-drawer snack buyers comparing fat
For someone who wants a portable cereal bar at work, total fat per 100g makes different-sized bars easier to compare. The amount per labelled serving then shows what is in the portion they plan to eat.
Who is comparing these bars?
Small-portion afternoon snackers
For someone choosing between a small bar and a larger oat-bar serving. Kellogg’s UK lists its Special K Red Berry Bar as 27g, while Nature Valley UK defines a Crunchy Oats & Honey serving as two bars weighing 42g.
Allergen and diet-label checkers
For someone buying for themselves or a shared office who needs to check the exact variant’s ingredients and suitability statements. The named Nature Valley and Eat Natural bars have different nut, milk and other allergen considerations.
What should you check?
Compare fat on a per-100g basis first, then look at the portion you would actually eat and the current pack’s ingredients.
| Priority | What to check | Your needs |
|---|---|---|
| Total fat and claims | Read total fat per 100g. For UK nutrition claims, the annex published by legislation.gov.uk sets a 3g-per-100g maximum for “low fat” on solid food; “reduced fat” requires at least 30% less than a similar product. | I want to compare bars without treating “less fat than another bar” as a verified low-fat or reduced-fat claim. |
| Serving size | Check the bar weight, the number of bars in a labelled serving and fat per serving. Kellogg’s UK lists a 27g Special K Red Berry Bar; Nature Valley UK lists two Crunchy Oats & Honey bars as a 42g serving. | A single small bar may suit my afternoon break, or I may prefer the two-bar portion. I want to know which portion the nutrition figures describe. |
| Other nutrition figures | Compare sugars and energy for the same labelled portions. Kellogg’s UK lists 7.6g sugars and 104 kcal for its 27g Red Berry Bar; Nature Valley UK lists 11.3g sugars for its two-bar, 42g serving. | Fat is not the only number I care about when choosing between a small cereal bar and a larger oat-bar serving. |
| Ingredients and allergens | Read the exact pack’s ingredient, allergen and may-contain statements. Check any vegetarian, vegan, lactose-free or gluten-free wording against that variant rather than the brand name. | If bars will go in a shared office drawer, I need to check whether each variant fits the people who may eat it. |
Common buying mistakes
-
Treating “lower than another bar” as a nutrition claim
A relative comparison does not, by itself, meet the UK claim conditions. The nutrition-claims annex published by legislation.gov.uk sets separate conditions for “low fat” and “reduced fat”.
Compare fat per 100g, and check any reduced-fat wording against the similar product used for that claim.
-
Comparing only the figures per bar
The manufacturer-listed Special K Red Berry bar is 27g, Nature Valley’s serving is two bars weighing 42g, and the named Eat Natural bars are 40g each. Portion figures alone therefore compare different amounts of food.
Use the per-100g figures for comparison, then check the figures for the portion you expect to eat.
-
Assuming a nut or protein bar contains less fat
Eat Natural UK lists 26.3g fat per 100g for Cashew & Blueberry and 30.1g per 100g for Hazelnut & Date. A bar’s ingredients or protein-bar format do not establish its total-fat content.
Check the exact variant’s nutrition panel if reducing total fat is your reason for choosing it.
-
Ordering a multipack from the product name alone
Serving weights and ingredients differ between variants. Nut, milk and other allergen statements can be decisive when bars are bought for more than one person.
Check the pack you receive, including its serving definition and may-contain statement.
Relevant brand references
These examples help distinguish the named products and formats; a brand name alone does not establish a bar’s fat content or dietary suitability.
Kellogg’s
Kellogg’s UK lists its 27g Special K Red Berry Bar at 6.3g fat per 100g and 1.7g per bar.
- The listed 27g bar contains 104 kcal.
- Its 6.3g fat per 100g exceeds the 3g-per-100g UK low-fat claim limit for solid food published by legislation.gov.uk. Check the nutrition panel of other Red Berry pack sizes separately.
Nature Valley
Nature Valley UK lists Crunchy Oats & Honey as a two-bar, 42g serving made with wholegrain oats.
- Its manufacturer-listed nutrition figures give both per-100g and two-bar serving values.
- Nature Valley UK lists 18.1g fat per 100g and 7.6g per two-bar serving; check its current may-contain statement if nuts or soya matter to you.
Graze
Graze describes its Oat Boost flapjacks in terms of sugar and saturated fat, rather than establishing a lower-total-fat choice among the named bars here.
- The Oat Boost range offers an oat-flapjack format to consider.
- Check total fat on the exact pack if that is your deciding measure; Graze’s sugar and saturated-fat statements answer different questions.
Eat Natural
Eat Natural UK lists fruit-and-nut bars including Cashew & Blueberry and Hazelnut & Date.
- The manufacturer lists fat per 100g and per 40g bar for both named variants.
- Those variants list 26.3g and 30.1g fat per 100g respectively. Both contain nuts, and the Cashew & Blueberry bar has a yoghurt coating containing milk.
Trek
Tesco Groceries lists Trek protein flapjacks, including Salted Caramel, as vegan.
- The listed format may be relevant when a vegan protein flapjack is the intended office snack.
- Check the exact pack’s total fat per 100g before choosing one for a lower-fat requirement.
Alpen
Alpen’s official FAQ identifies several former cereal-bar variants, including Alpen Light Bars Chocolate & Orange, as no longer made.
- Do not use an older listing for one of those variants as the nutrition information for a different current product.

Questions about choosing a bar
Does less fat than another bar mean “reduced fat” in the UK?
No. The nutrition-claims annex published by legislation.gov.uk requires a reduction of at least 30% compared with a similar product for a reduced-nutrient claim. Compare the product and its stated comparator rather than relying on two unrelated fat figures.
Is the manufacturer-listed Special K Red Berry Bar low fat?
No. Kellogg’s UK lists 6.3g fat per 100g for its 27g Red Berry Bar, while the UK low-fat claim condition for solid food published by legislation.gov.uk is no more than 3g per 100g. Check the separate nutrition panel for the 21.5g-bar multipack listed on Joybuy.
What matters when buying bars for a shared office drawer?
Check the exact pack’s ingredients, allergen and may-contain statements, along with its serving size. Nature Valley UK flags possible nut and soya ingredients for Crunchy Oats & Honey; the named Eat Natural bars contain nuts, and Cashew & Blueberry has a milk-containing yoghurt coating.
Can I rely on an older Alpen bar listing?
Not for the nutrition or availability of a current variant. Alpen’s official FAQ says several former bars, including Alpen Light Bars Chocolate & Orange, are no longer made; check the identity and label of any Alpen product you are considering now.
