Who is this for?

Parents comparing fat content

If you need a bar for a holiday outing, compare fat per 100g as well as per bar. A smaller serving or a ‘light’ name cannot tell you how bars of different sizes compare.

Families checking allergies or dietary requirements

Ingredients and may-contain warnings differ between the named bars. Check the exact wrapper against the child’s requirements and any rules set by the activity provider.

Families comparing snack sizes and formats

A small cereal bar and a larger flapjack provide different portions. Compare the amount per bar and any protein or fibre figures you care about without assuming those features mean less fat.

What should you check?

Start with a like-for-like comparison per 100g, then check the portion you would pack and whether the ingredients suit the child.

PriorityWhat to checkYour needs
Total fat Compare total fat per 100g across bars. The NHS describes 3g or less per 100g as low fat; check any reduced-fat claim on the exact pack rather than inferring one from its name. I’m looking for a lower-fat option, not just a bar with a small number of grams of fat because its portion is small.
Portion and label Check the bar’s weight and its per-bar figures alongside the per-100g panel. Compare sugars, saturated fat, salt and energy as well as total fat. For an outing, I want to know what is in the bar I will actually pack, without treating ‘no added sugar’ as a claim about total sugars or fat.
Allergens Read the current ingredients, highlighted allergens and may-contain statement. Check dietary wording against the exact variety, not another bar from the same brand. A suitable portion or fat figure is no use to my child if the bar conflicts with their allergy requirements or the activity provider’s food rules.

Common mistakes to avoid

  • Taking ‘light’ or a small bar to mean low fat

    A small bar can have little fat per serving while exceeding the NHS low-fat guideline when measured per 100g. Weetabix Cereals lists Alpen Light Summer Fruit at 0.8g per 19g bar but 4.3g per 100g.

    Compare per 100g first, then use the per-bar figure for the portion you plan to pack. Check any reduced-fat wording on the current pack separately.

  • Using a sugar or protein claim as a fat comparison

    The named examples show why these are separate label questions: Tesco Groceries lists 22g fat per 100g for Graze Cocoa Vanilla Oat Boosts and 23g for Nakd Peanut Delight, despite their respective lower-sugar and no-added-sugar positioning.

    Read total fat, saturated fat and sugars from the same nutrition panel rather than using a front-of-pack claim to answer a different question.

  • Missing allergen and may-contain warnings

    The checked ranges include bars with nuts, peanuts, milk, soya or gluten-containing ingredients, and some carry additional may-contain warnings. A bar chosen for its nutrition figures may therefore be unsuitable for a particular child.

    Check the current wrapper against the child’s allergy requirements and any food rules for the outing before packing it.

Brand and range references

These figures describe the named varieties, not every bar made by each brand; compare the current pack when choosing a flavour or size.

Alpen

Weetabix Cereals lists Alpen Light Summer Fruit at 4.3g fat per 100g and 0.8g per 19g bar.

  • The per-100g figure is below those of the other named comparison bars on this page.
  • It exceeds the NHS guideline of 3g fat or less per 100g for low fat. Weetabix Cereals also states that it is unsuitable for people with nut allergies.

Graze

Graze Cocoa Vanilla Oat Boosts are presented with a lower-sugar comparison; Tesco Groceries lists 22g fat per 100g for this variety.

  • The stated sugar comparison concerns more than 80 cereal bars, according to the product wording shown by Tesco Groceries.
  • A lower-sugar comparison does not make this variety low in fat.

Nakd

Nakd describes its fruit-and-nut bars as having no added sugar. Tesco Groceries lists 23g fat and 35g total sugars per 100g for Peanut Delight.

  • Nakd describes its fruit-and-nut range as vegan, gluten-free and dairy-free.
  • The Peanut Delight figures show that no added sugar does not mean low total sugars or low fat; check peanut and other allergen warnings on the exact variety.

Nature Valley

Nature Valley lists 25.7g fat per 100g for its Protein + Fibre Coconut & Almond Flavour bar.

  • This named variety offers a protein-and-fibre format for shoppers comparing those label figures.
  • It is not a low-fat choice under the NHS per-100g guideline. Nature Valley lists almond, peanut, soya, milk, wheat and barley ingredients for this bar.

Trek

The Myprotein UK listing for Trek Original Oat Protein Flapjack gives 19.6g fat per 100g.

  • The flapjack format gives shoppers a different portion size to compare with smaller cereal bars.
  • It exceeds the NHS low-fat guideline; check its soya ingredients and may-contain warnings on the current pack.

Eat Natural

Tesco Groceries lists Eat Natural Peanuts, Almonds & Cocoa at 37.9g fat per 100g and 15.2g per 40g bar.

  • The same listing gives 8g protein per 40g bar for shoppers comparing that figure.
  • Its fat figures do not fit a lower-fat priority; check its peanut, almond and may-contain warnings before packing it for a child.

Frequently asked questions

Does ‘light’ mean a snack bar is low in fat?

No. The NHS low-fat guideline is 3g fat or less per 100g. Weetabix Cereals lists Alpen Light Summer Fruit at 0.8g per 19g bar but 4.3g per 100g, so check the per-100g panel rather than relying on the name or portion size.

Is a ‘no added sugar’ bar necessarily lower in fat?

No. Tesco Groceries lists 23g fat and 35g total sugars per 100g for Nakd Peanut Delight. ‘No added sugar’ answers a different question from total fat or total sugars, so compare those figures on the exact bar you are considering.

What should I check before packing a bar for a child with allergies?

Read the current wrapper’s ingredients, highlighted allergens and may-contain statement against the child’s requirements. The named examples differ in their nut, peanut, milk, soya and gluten-containing ingredients; also check any food rules set by the activity provider.

Does a protein bar meet a lower-fat priority?

Not on the strength of its protein label. Nature Valley lists 25.7g fat per 100g for Protein + Fibre Coconut & Almond Flavour, while the Myprotein UK listing gives 19.6g per 100g for Trek Original Oat Protein Flapjack. Compare fat per 100g and the allergens of the exact bar before choosing it for an outing.
