Who is this for?

Calorie-conscious elevenses planners

If you plan to eat one bar or a whole wrapper mid-morning, compare calories for that amount. The per-100g figure alone does not tell you the total for your snack.

Oat-bar shoppers interested in fibre

If you prefer an oat flapjack to a smaller cereal bar, check its declared serving and fibre information alongside its calories and allergen statement. Waitrose & Partners lists Graze Honey Oat Boost as high in fibre at 129 kcal per 30g bar.

Shoppers considering a protein flapjack

If protein matters more to you than choosing the smallest-calorie bar, compare both figures for the whole flapjack. TREK lists its Cocoa Oat bar at 9g protein and 227 kcal per 50g bar.

What should you check?

Decide how much of the pack you will eat at elevenses before comparing the nutrition information for that portion.

PriorityWhat to checkYour needs
Calories per snack Check kcal for one bar and for the full wrapper if it holds two. Compare the amount you plan to eat, not just the per-100g figure. I want to know the calorie total for my actual mid-morning portion, whether that is one bar or both bars in a wrapper.
Other nutrition information Read sugars, saturates and salt alongside calories, using the same portion basis. GOV.UK guidance says traffic-light labels, where present, show these nutrients as well as calories and fat. A lower calorie figure is not the only detail I want to compare when choosing between bars.
Bar size, fibre and protein Check the bar's weight and its stated fibre or protein information. A claim about either nutrient does not tell you the bar's calorie total. For a larger oat bar or a protein flapjack, I want to see how its portion and calories compare with a smaller cereal bar.
Ingredients and allergens Check the exact pack's ingredients, declared allergens and any may-contain statement. Confirm vegan, vegetarian or gluten-free suitability on that product rather than inferring it from its flavour or oats. If I need to avoid a particular ingredient, the label on the bar I am buying matters more than its calorie figure.

Common buying mistakes

  • Counting a twin wrapper as one small bar

    ASDA Groceries lists Nature Valley Crunchy Oats & Honey at 196 kcal and 11.3g sugars for its two-bar, 42g portion. Counting just one internal bar understates the total if you eat both.

    Decide whether you will eat one bar or the full wrapper, then compare nutrition figures for that amount.

  • Assuming protein means fewer calories

    TREK lists 9g protein but also 227 kcal, 14g sugars and 5g saturates per 50g Cocoa Oat flapjack.

    Choose a protein-focused bar for its stated protein content if that is your priority, while checking its calories for the whole bar.

  • Using a pack claim as the whole nutrition comparison

    Graze's 45% less-sugar statement compares its Oat Boost flapjacks with more than 80 cereal bars. That comparison does not describe every nutrient or establish that a particular bar has fewer calories.

    Read the exact product's calories, sugars, saturates and salt per portion rather than relying on one front-of-pack claim.

  • Overlooking the allergen statement

    The cereal bars compared here have different declared or may-contain allergens, including gluten-containing cereals, milk, soya, peanuts and nuts.

    If you need to avoid an ingredient, check the current physical pack's ingredients and precautionary allergen statement before eating.

Brand and product-line references

Compare the exact bar and serving: a brand name alone does not establish its calories or dietary suitability.

Kellogg's

Its Special K Juicy Red Berry bar is an individually portioned option for a small elevenses snack.

  • ASDA Groceries lists 83 kcal per 21.5g bar.
  • The same listing gives 1.3g protein and 2.1g fibre per bar and identifies barley, milk, oats, wheat and soya as allergens. Consider whether the portion suits the snack you have planned.

Graze

The Honey Oat Boost is a 30g oat-flapjack option for shoppers comparing portion size and fibre as well as calories.

  • Waitrose & Partners lists it at 129 kcal per bar and labels it high in fibre.
  • Check its may-contain allergen statement. Graze's comparison of its Oat Boost flapjacks with more than 80 cereal bars is a brand sugar claim, not an overall nutrition comparison.

Nature Valley

Crunchy Oats & Honey suits a preference for a crunchy oat bar, provided you count the portion you will eat.

  • Nature Valley describes its Crunchy bars as made with wholegrain oats.
  • ASDA Groceries lists 196 kcal and 11.3g sugars for the full two-bar, 42g portion; it may contain peanuts, wheat, soya and nuts.

TREK

The vegan Cocoa Oat flapjack is a protein-focused option rather than the smallest-calorie option among these examples.

  • TREK lists 9g protein per 50g bar.
  • TREK also lists 227 kcal, 14g sugars and 5g saturates per bar, with a may-contain warning for peanuts, nuts and milk.

Eat Natural

Its UK range includes fruit-and-nut and other cereal-bar formats for shoppers comparing ingredients and dietary labels.

  • Eat Natural identifies vegan, gluten-free and high-fibre options within its UK range.
  • These descriptions apply to particular products, not every Eat Natural bar. Check the exact bar's nutrition and allergen declaration before choosing it for elevenses.

Alpen

Shoppers familiar with Alpen Light bars should check the current product name rather than relying on a former range.

  • Alpen remains a recognisable reference for shoppers comparing cereal-bar formats.
  • Alpen's UK FAQ lists several former bar lines, including Alpen Light Bars Chocolate & Orange, as no longer made.

Questions about cereal bars for elevenses

Which of these cereal bars has the fewest calories per stated portion?

Among the four examples compared, Kellogg's Special K Juicy Red Berry has the lowest declared total at 83 kcal per 21.5g bar, according to ASDA Groceries. Waitrose & Partners lists Graze Honey Oat Boost at 129 kcal per 30g bar; ASDA Groceries lists Nature Valley Crunchy Oats & Honey at 196 kcal for its two-bar, 42g portion; and TREK lists Cocoa Oat at 227 kcal per 50g bar. Compare the exact bar and amount you intend to eat.

Should I compare calories per 100g or per bar?

For elevenses, start with calories for the bar or wrapper you plan to eat. The per-100g figure helps compare products on the same weight basis, but it does not give your snack's calorie total unless you also account for its portion size.

Does a high-fibre or protein label mean fewer calories?

No: fibre and protein describe different attributes from calories. Waitrose & Partners labels Graze Honey Oat Boost high in fibre at 129 kcal per 30g bar, while TREK lists 9g protein and 227 kcal per 50g Cocoa Oat flapjack. Check each product's full portion and nutrition panel.

How can traffic-light labels help me compare bars?

Where displayed, traffic-light labels let you compare calories, fat, saturates, sugars and salt, as explained in GOV.UK's label guidance. A red indicator means a high level of the nutrient it marks; read it alongside the portion size and the full ingredient and allergen information.

What if I need to avoid an allergen?

Check the ingredients and may-contain statement on the exact physical pack before eating. The compared bars differ: ASDA Groceries identifies barley, milk, oats, wheat and soya in Kellogg's Special K Juicy Red Berry, while its Nature Valley listing warns of possible peanuts, wheat, soya and nuts; other variants need their own pack check.
