People counting carbohydrates

If you count carbohydrates, the useful label figure is the total for the amount you will eat. Diabetes UK advises checking total carbohydrate rather than relying on the front-of-pack sugar information alone.

Shoppers planning snacks from a multipack

A pack may contain individually sized bars or twin-bar portions. Check the wrapping and stated serving so that the amount you plan to eat matches the nutrition figure you use.

People following a smaller-carbohydrate snack plan

If a plan you already follow calls for a snack around 10g carbohydrate, compare that amount with the current label. A smaller bar and a twin-bar serving should not be treated as equivalent portions.

What to check before buying

Start with the portion you expect to eat, then compare its label figures and the number of usable portions in the pack.

PriorityWhat to checkYour needs
Total carbohydrate Read total carbohydrate for the bar or wrapped portion you will eat. Use the per-100g figure alongside portion figures when bar sizes differ. I count carbohydrates for a planned snack, so I need the figure for my actual portion, including both bars if I eat a twin pack. Diabetes UK advises checking total carbohydrate, not sugars alone.
Sugars and ingredients Check sugars per portion and per 100g, then read the ingredients list. The NHS classifies more than 22.5g total sugars per 100g as high on food labels; a sugar traffic light does not state total carbohydrate. An oat or fruit description would not tell me how much sugar or total carbohydrate the bar contains. I want to compare the figures on the current pack.
Pack portions Count bars and check whether the stated serving is one bar or a twin-bar wrapper. Compare packs using the number of portions you would actually eat. I am buying several snacks at once and want each planned eating occasion to match the portion used on the nutrition label.
Allergens and current recipe Read the ingredient and allergen statements on the pack you are buying. Check the best-before date before choosing a larger quantity. I need a pack whose ingredients suit everyone who will eat it, without assuming that another flavour or an earlier pack has the same recipe.

Common buying mistakes

  • Assuming an oat bar has less carbohydrate

    Oats in the name do not establish the carbohydrate amount. Nature Valley states 27g carbohydrate for its Crunchy Oats & Honey 42g twin-bar portion, while Kellogg's states 25g for one 37g Nutri-Grain Apple bar.

    Compare the total carbohydrate for the portion you intend to eat, rather than choosing by the front of the pack.

  • Counting bars without checking the wrapper

    Nature Valley's Crunchy Oats & Honey Family Pack contains 20 x 21g bars, but its stated serving is a 42g twin-bar portion. Two bars eaten together are not the same portion as one bar.

    Check how many bars are wrapped together and use the nutrition figure for the amount you normally eat.

  • Using the sugar traffic light as a carbohydrate figure

    A front-of-pack sugar indicator does not give total carbohydrate. Diabetes UK advises checking the total-carbohydrate line, which includes more than sugars.

    Read both the per-portion and per-100g information on the nutrition panel, keeping the portion size in view.

  • Buying several packs before checking allergens

    Ingredients and allergen statements differ between the cereal bars discussed here, and recipes can change. An unsuitable ingredient can make a large pack unusable for its intended shopper.

    Check the current pack's ingredients, allergen statement, nutrition panel and best-before date before buying a larger quantity.

Frequently asked questions

Are cereal bars automatically suitable for someone with diabetes?

No. Diabetes UK cautions that cereal bars can contain substantial amounts of sugar and advises checking total carbohydrate. Compare the portion you intend to eat with your own carbohydrate plan, then check sugars, ingredients and allergens rather than relying on the bar's name or packaging.

Does a lower sugar traffic light mean less total carbohydrate?

Not necessarily. Front-of-pack sugar information does not give total carbohydrate, which also includes carbohydrate from ingredients other than sugars. Diabetes UK advises checking the nutrition panel's total-carbohydrate figure per 100g and, where shown, per portion.

How should I compare cereal-bar multipack sizes?

Count the portions you expect to eat, not just the bars in the box. Nature Valley's Crunchy Oats & Honey Family Pack contains 20 x 21g bars but states nutrition for a 42g twin-bar serving; check the carbohydrate for your intended portion, along with the current allergen information, before choosing a pack size.
