Choose the wrapper format and portion size before comparing nutrition: an eight-bar pack is useful for keeping individually portioned bars at work, while a four-pack of 30g oat flapjacks suits someone who wants smaller portions. If protein, fibre, vegan or gluten-free labelling matters, compare the exact flavour rather than the brand as a whole. Check the current pack for ingredients and allergens, and compare nutrition per portion as well as per 100g.
If you put a bar into your packed lunch or keep a few in a desk drawer, check the number of wrapped portions. Nature Valley’s Crunchy Variety pack, for example, has 20 bars but 10 two-bar pouches, according to Nature Valley UK.
Look at the values for the portion you would eat. Nature Valley UK lists around 10g protein and 4g fibre per 40g Protein Peanut & Chocolate bar; Tesco lists 4.6g fibre per 30g Graze Peanut Butter Oat Boost.
Choose by exact flavour and current pack, not by a brand-wide description. The researched options include products labelled vegan or gluten free, while ingredients such as peanuts, oats and soya differ between bars.
Start with how many wrapped portions you need, then compare the nutrition and ingredient information for the bars you would actually pack.
| Priority | What to check | Your needs |
|---|---|---|
| Pack format | Check the number of wrapped portions, bars per wrapper and weight per portion. Nature Valley UK lists its Crunchy Variety pack as 20 bars in 10 two-bar pouches. | I want to take one wrapped portion to work without opening the rest of the pack. If one bar is my usual portion, a two-bar pouch needs more thought than a single-bar wrapper. |
| Protein and fibre | Compare declared amounts for the same serving size. Nature Valley UK lists around 10g protein and 4g fibre per 40g Protein Peanut & Chocolate bar; Tesco lists 4.6g fibre per 30g Graze Peanut Butter Oat Boost. | Protein or fibre is important to my choice, so I want the amount for the particular bar and portion—not just a claim on the front of the pack. |
| Energy and sugars | Read values per portion and per 100g. As the NHS explains, nutrition information is provided per 100g and may also be given per portion; portion weights differ between these multipacks. | I want to know what is in the portion going into my lunch, while using per-100g figures when comparing bars of different sizes. |
| Diet and allergens | Check the exact flavour’s current ingredients, dietary labels and allergen statement, including any ‘may contain’ wording. Tesco labels TREK Cocoa Oat as vegan and gluten free, but the researched flapjack uses soya protein crispies. | Whether I need a vegan or gluten-free option, or must avoid an ingredient, the label on the particular pack matters more than the product range’s name. |
Nature Valley UK describes its Crunchy Variety pack as 20 bars in 10 two-bar pouches. Opening one pouch gives you two bars, even if you meant to pack only one.
Check how many bars are in each wrapper before deciding how long a multipack will cover your office lunches.
Ingredients differ by flavour: Tesco lists peanuts, oats and soya for Graze Peanut Butter Oat Boost, while Nature Valley’s Protein Peanut & Chocolate bar contains peanuts, soya and milk.
Read the current ingredients and allergen statement for the exact pack, including any ‘may contain’ information.
A 30g oat boost and a 50g flapjack are different-sized portions. A per-bar figure alone does not provide a like-for-like comparison.
Use per-portion values to assess what you plan to eat and per-100g values to compare products consistently, as the NHS’s food-label guidance explains.

This three-pack gives you 50g flapjacks for individual lunches. Check the Biscoff variant’s ingredients and dietary labels specifically: the vegan and gluten-free labelling cited for TREK Cocoa Oat cannot be applied to another flavour.
Use both: per-portion figures describe what you plan to put in your lunch, while per-100g figures help compare different-sized bars. The NHS explains that nutrition information is provided per 100g and may also appear per portion.
No. Check the amount for the exact bar alongside its portion size, sugars and ingredients. Nature Valley UK lists around 10g protein and 4g fibre per 40g Protein Peanut & Chocolate bar, which also contains peanuts, soya and milk.
Tesco labels the researched TREK Cocoa Oat three-pack vegan and gluten free, and its Eat Natural Maple Syrup, Pecans & Peanuts three-pack listing gives both descriptions. Check the exact flavour’s current pack; those labels should not be assumed for other products from either brand.
Use it to narrow your choice, then check the current pack’s ingredients and allergen statement before eating. Kellogg’s advises checking packs because recipes can change, and allergen information differs between the cereal bars discussed here.
