Who is choosing?

Snackers comparing total fat

If you want a portioned sweet snack for the film, compare fat per 100g as well as per bar. A small bar can have a small per-bar figure without telling you how it compares with a larger one.

People buying snacks to share

If guests have dietary restrictions or allergies, check each bar’s current ingredients and allergen statement. Vegan or gluten-free wording answers a different question from whether a product contains nuts, milk or soya.

Protein-bar shoppers also watching fat

If you prefer a protein bar, compare its total fat, saturates, sugars and bar weight separately. Protein positioning does not establish that a flapjack is lower in fat.

What should you compare?

Start with the per-100g nutrition figures to compare different bars, then use the per-bar figures and pack label to decide what works for the amount you plan to serve.

Priority What to check Your needs
Total fat Compare declared fat per 100g on the same basis. Then check fat per bar and the number of bars you expect to eat. I’m looking for a lower-fat choice, not relying on words such as “protein” or “natural” to tell me its fat content.
Portion size Check the bar weight, servings in the pack and per-bar nutrition. For more than one bar, add the stated per-bar amounts together. One small bar might suit me, but I may want more than one during a film.
Sugars and saturates Read both figures per 100g and per bar; total fat alone does not describe the rest of the nutrition panel. Check the current pack’s traffic-light labelling where provided. Lower total fat is my starting point, but I also want to compare sugars and saturates before choosing.
Sharing and allergies Read the current ingredients, named allergens and any “may contain” statement. Assess vegan or gluten-free wording separately from allergy information. I’m sharing the pack, so I need to check whether each guest can have that exact bar.

What is easy to overlook?

  • Treating one small bar as the whole movie-night portion

    Weetabix Cereals lists Alpen Light Chocolate & Fudge at 1.2g fat per 19g bar. Eating several bars changes the total even though the figure printed for one bar stays the same.

    Decide how many bars you are likely to have, then use the per-bar fat, sugars and energy figures to assess that amount.

  • Assuming protein or vegan wording means less fat

    The product panels list 22g fat per 100g for TREK Cocoa Oat, 27.1g for Nature Valley Protein + Fibre Chocolate & Orange and 36.3g for Eat Natural Dark Chocolate & Peanut Protein Bar. Their positioning does not replace a fat comparison.

    Choose for protein or dietary suitability if those features matter to you, but compare total fat and the other nutrition figures separately.

  • Overlooking allergen statements on a sharing pack

    The bars discussed here include nut, peanut, milk, soya, oat or wheat ingredients or warnings. The Food Standards Agency explains that precautionary allergen labelling communicates possible unintended allergen presence.

    Check the label on the pack you are buying for every guest with a relevant allergy; do not use vegan or gluten-free wording as a substitute.

  • Using “reduced fat” as a label for any bar with less fat

    A comparison of declared fat figures tells you how these particular bars differ; it does not establish what claim appears on an individual product’s pack.

    For shopping comparisons, state the fat figures and their basis. Check the current pack if its “reduced fat” wording matters to your choice.

Brand examples and their differences

These figures describe the named bars, not every product made by each brand. Compare the exact variety and serving size on its current pack.

Alpen

Alpen Light Chocolate & Fudge is a small cereal-bar example for comparing total fat.

  • Weetabix Cereals lists 6.5g fat per 100g and 1.2g per 19g bar for this Light variety.
  • Those figures do not describe the whole Alpen range: its Fruit, Nut & Chocolate bar is listed at 13g fat per 100g. Check the Light bar’s allergen label before sharing.

nākd.

Cocoa Delight is a fruit-and-nut cocoa bar for shoppers considering vegan or gluten-free options.

  • nākd. lists 14g fat per 100g and 4.9g per 35g bar.
  • Cocoa Delight contains cashews. Its dietary positioning does not replace a check of the full ingredients and allergen statement.

Graze

Cocoa Vanilla Oat Boosts offer a 30g oat-based portion.

  • Waitrose & Partners lists 6.5g fat per 30g boost.
  • The same listing gives 22g fat per 100g. Compare that figure, rather than the smaller per-boost number alone, when fat is your main criterion.

TREK

Cocoa Oat is a protein flapjack for shoppers who want to compare protein-bar features with fat content.

  • TREK lists 11g fat per 50g bar.
  • Its panel lists 22g fat and 10g saturates per 100g. Check its soya and precautionary allergen information before sharing.

Nature Valley

Protein + Fibre Chocolate & Orange is a protein-and-fibre bar, rather than a shortcut to choosing by fat content.

  • Nature Valley lists 7.1g protein and 6.5g fibre per 36g bar.
  • The same product lists 27.1g fat per 100g and contains peanut, soya and milk ingredients.

Eat Natural

Dark Chocolate & Peanut Protein Bar is a nut-and-chocolate option for shoppers considering a protein bar.

  • Eat Natural lists 19.5g protein per 100g for this bar.
  • It also lists 36.3g fat per 100g and 14.5g per 40g bar. Check the peanut and other allergen information on the pack.

Common questions

Is the bar with the least fat per 100g always the right movie-night choice?

It is a useful starting point if reducing total fat is your main aim, but also check the bar weight and how many you plan to eat. Compare sugars, saturates and allergens before choosing a pack to share.

Does “protein”, “natural” or vegan mean a bar has less fat?

No: those descriptions do not give you a comparable fat figure. The named product panels list 14g fat per 100g for nākd. Cocoa Delight, 22g for TREK Cocoa Oat and 27.1g for Nature Valley Protein + Fibre Chocolate & Orange. Check the exact variety’s nutrition panel instead.

Why check sugars and saturates as well as total fat?

Total fat describes only one part of a bar’s nutrition panel. Action on Salt & Sugar’s November 2025 analysis of 458 snack bars across 10 major UK retailers reported that 55% were high in saturated fat and 37% were high in sugars under UK front-of-pack thresholds; those are proportions of products reviewed, not of shoppers. Check the figures for the bar you are considering.

What should I check before sharing bars with someone who has an allergy?

Read the current pack’s ingredients, named allergens and any “may contain” statement for the exact variety. The Food Standards Agency explains that precautionary allergen labelling communicates possible unintended presence of regulated allergens; vegan or gluten-free wording does not replace that check.
