Shoppers topping up portable snacks
If bars are going into a bag, desk drawer or lunchbox, compare the size of each bar as well as the number in the pack. The product examples considered here range from 19g to 50g per bar.
Who is choosing these bars?
Shoppers looking for declared protein
If protein per bar is a deciding factor, read the figure for the exact product rather than assuming that every oat, nut or cereal bar provides the same amount. Check its other nutrition information and ingredients too.
Shoppers with dietary or allergen requirements
Look for the required claim on the specific pack, then read its ingredients and allergen statement. Vegan or gluten-free labelling does not, by itself, resolve a nut, peanut or soya allergy question.
What should you compare?
Start with the size and type of bar you want to carry, then compare the nutrition panel and ingredients for that exact variant.
| Priority | What to check | Your needs |
|---|---|---|
| Portion size | Check grams per bar and bars per pack. Use per-bar figures for the portion you plan to eat and per-100g figures to compare differently sized products, as the NHS explains in its food-label guidance. | I want a bar that fits this snack occasion, rather than choosing by a smaller per-bar number without noticing the bar’s weight. |
| Declared protein | Read protein per bar alongside bar weight, sugars and saturates. Tesco Groceries lists 10g protein for a 40g Nature Valley Protein variety-pack bar and 9g for a 50g TREK Peanut Butter Protein Flapjack. | Protein is one reason I am buying the bar, but I still want to compare the whole panel and the ingredients. |
| Total sugars | Compare total sugars per bar and per 100g, not just a front-of-pack phrase. Tesco Groceries lists 17g sugars per 35g Nakd Berry Delight bar despite its no-added-sugar claim. | If sugar content matters to my choice, I want the total for the portion I will eat. “No added sugar” does not tell me that total. |
| Dietary claims and allergens | Check claims on the exact variant, then read its ingredients and precautionary allergen statement. Pay particular attention to the allergens relevant to you; a gluten-free or vegan claim addresses a different question. | I need to establish whether this particular bar meets my requirements, rather than relying on the brand or bar category. |
What can be easy to miss?
-
Reading “no added sugar” as “low in total sugars”
Nakd Berry Delight is described as having no added sugar, while Tesco Groceries lists 17g total sugars per 35g bar from naturally occurring sugars.
Read total sugars on the nutrition panel for both the bar and 100g before comparing it with another product.
-
Comparing per-bar figures without checking weight
The examples include 19g Alpen bars and 50g TREK flapjacks. Their per-bar nutrition figures describe different-sized portions.
Use per-bar figures for your planned snack and per-100g figures when comparing products of unequal weight.
-
Letting a dietary claim stand in for an allergen check
A bar can carry a vegan or gluten-free claim and still contain nuts or have precautionary allergen information. The checked Nakd Berry Delight bar contains cashew.
Read the ingredients and allergen statement on the exact pack, especially when avoiding nuts, peanuts, soya or milk.
-
Relying on a brand claim for every flavour
Nutrition, ingredients and dietary labelling need to be checked for the variant you are buying; a claim about one bar does not establish the details of another.
Use an online listing to narrow your choices, then confirm the physical pack’s nutrition, ingredients, allergens and best-before information.

Questions about snack-bar multipacks
Does “no added sugar” mean a snack bar is low in total sugars?
No. Check total sugars on the nutrition panel. Tesco Groceries lists 17g sugars per 35g Nakd Berry Delight bar, described as naturally occurring, even though the product carries a no-added-sugar claim.
Should I compare snack bars per bar or per 100g?
Use both figures for different purposes. The per-bar figure describes the portion you plan to eat; the per-100g figure helps you compare bars of different weights. The NHS notes that food labels provide nutrition per 100g and sometimes per portion.
Does vegan or gluten-free labelling settle a nut or soya allergy question?
No. Those claims do not replace an ingredient and allergen check. The checked Nakd Berry Delight bar contains cashew, while the checked TREK Peanut Butter flapjack contains peanuts and soya; read the exact pack and its precautionary statements.
Where should I check a snack bar for allergens?
Read the ingredient list and any precautionary allergen statement on the specific pack. Food Standards Agency and Food Standards Scotland guidance explains how allergen information is presented for pre-packed food; a general brand description is not a substitute for the bar’s label.
How should I store a snack-bar multipack?
Follow the storage instructions and best-before information on the pack you buy. The checked Nakd and Eat Natural multipacks specify a cool, dry place, but the exact product’s directions should guide storage.
