Hosts offering a low-fat choice
Compare total fat per 100g on each bar’s current pack, then check the portion size when deciding how many to put out.
Who is choosing?
Hosts serving guests with different dietary needs
Keep ingredient and allergen information accessible when offering bars with different recipes or dietary labels.
Guests choosing protein or fibre bars
Check those nutrients alongside total fat and allergens rather than assuming a protein or fibre claim means lower fat.
What should you check?
Compare bars per 100g first, then use the per-bar figures and the exact pack to decide what to serve.
| Priority | What to check | Your needs |
|---|---|---|
| Low-fat choice | Check total fat per 100g. UK government guidance sets the threshold for a solid food claiming to be low fat at no more than 3g per 100g; check saturates separately. | I want a bar that meets the low-fat threshold, not just one labelled with a different nutrition claim. |
| Label comparison | Compare per-100g values across bars before reading per-bar figures. Check what the traffic-light colours refer to rather than relying on the front of the pack alone. | When shopping for a group, I want to compare different-sized bars consistently. In the Food Standards Agency’s Northern Ireland Making Food Better survey, 49% of 611 adults interviewed between September and November 2024 said they actively used traffic-light labelling when shopping for food; this was not a measure of street-party purchases. |
| Allergen information | Read the ingredients and allergen statement for each variety. Keep its original wrapper or outer pack available when serving. | Guests need to be able to check the exact bar before taking it, particularly when the selection includes nuts, milk or soya. |
| Protein or fibre | Check the stated protein or fibre amount and its serving size, then compare total fat per 100g and read the allergen information. | I may want a protein or fibre bar, but that is a separate choice from meeting the low-fat threshold. |
Common buying mistakes
-
Taking protein, fibre or vegan wording to mean low fat
These describe different attributes. Nature Valley UK lists 27.1g fat per 100g for its Protein + Fibre Chocolate & Orange bar, while nākd. lists 14g per 100g for Cocoa Delight; neither figure meets the 3g-per-100g low-fat threshold stated in UK government guidance.
If low fat is the requirement, check total fat per 100g on the exact pack before considering its other attributes.
-
Comparing only the fat shown per bar
Different bar sizes make per-portion figures a poor like-for-like comparison. The NHS explains that nutrition information is provided per 100g and may also be shown per portion.
Compare per-100g values first, then use per-bar figures to plan what you will serve.
-
Putting out bars without their packaging
Guests may need the exact ingredient and allergen information before choosing. Food Standards Agency community-event guidance recommends keeping packaging for prepacked food so people with food hypersensitivities can check it.
Leave wrappers accessible and retain an outer pack for each variety.
-
Relying on an old bar name
Alpen Muesli lists Alpen Light Bars Chocolate & Orange among products it no longer makes. An older listing or label does not establish the details of a bar being offered now.
Check the exact product and its current nutrition panel before including it as a low-fat choice.

Graze
Graze describes its snack range using nutrition criteria and makes a separate saturated-fat claim about its Oat Boost flapjacks.
- The Oat Boost range is relevant if you are comparing flapjack formats.
- Graze’s range-level claims do not establish that an individual bar meets the low-fat threshold; check its current panel.
Nature Valley
Its oat and protein-bar formats serve different selection needs.
- Nature Valley UK lists 7.1g protein and 6.5g fibre per 36g Protein + Fibre Chocolate & Orange bar.
- The same bar lists 27.1g total fat per 100g, so it does not meet the UK low-fat threshold for solid foods.
nākd.
Its Cocoa Delight fruit-and-nut bar is listed by nākd. as vegan, gluten-free and dairy-free.
- The Cocoa Delight ingredients include dates, cashews and raisins.
- Cocoa Delight contains cashews and lists 14g fat per 100g; it is not a low-fat or nut-free choice.
Eat Natural
Its Dark Chocolate & Peanut Protein Bar is an example of a peanut-and-soya protein-bar format.
- The named bar gives shoppers a specific recipe to assess against their protein-bar requirements.
- Eat Natural UK lists 36.3g fat per 100g for this bar and identifies peanuts and soya in its ingredients.
Alpen
Alpen Muesli’s product information is useful when checking whether an older bar name still refers to a current product.
- Alpen Muesli lists Alpen Light Bars Chocolate & Orange among products it no longer makes; do not use its historic branding as a current nutrition check.

Frequently asked questions
Does “reduced fat” mean a snack bar is low fat?
No. A comparison with another product does not establish that the bar meets the low-fat threshold. UK government guidance says a solid food claiming to be low fat must contain no more than 3g fat per 100g, so check total fat on the current pack.
Can protein bars be the low-fat choice?
Only if the specific bar meets the low-fat threshold. Nature Valley UK lists 27.1g fat per 100g for its Protein + Fibre Chocolate & Orange bar and 28.3g per 100g for its Peanut & Chocolate protein bar; protein content alone does not answer the fat question.
Should I keep snack-bar wrappers at a street party?
Yes, keep the original packaging accessible so guests can inspect ingredients and allergens. Food Standards Agency guidance for community events recommends retaining packaging for prepacked food when people with food hypersensitivities may need to check it.
Should I serve loose bars in an unlabelled bowl?
Not as the only way for guests to identify them. Keep each variety’s original packaging available so people can check which bar they are taking and read its ingredients before choosing.
