Shoppers who want one defined portion
If one bar is your planned TV snack, compare protein, energy, sugars and fibre for that bar, not just the claims on the front of the pack.
Who is choosing a TV-night snack bar?
Vegan or dairy-free shoppers
Check the exact product’s suitability statement and ingredients. TREK describes its bars as plant-based, and Tesco labels Nakd Peanut Butter Protein vegan; Nature Valley Protein Peanut & Chocolate contains milk.
Shoppers checking allergens
Peanut, tree-nut, soya and milk declarations can change the choice. Read both the ingredients and any ‘may contain’ statement on the current pack.
What should you compare?
Start with the figures for one bar, then check whether its ingredients and portion suit the snack you have in mind.
| Priority | What to check | Your needs |
|---|---|---|
| Protein | Compare grams per bar and the bar’s energy. A protein-related name alone does not tell you how much of its energy comes from protein. | I want to know how much protein I get in the portion I plan to eat, rather than choose by the product name. |
| Energy and sugars | Read kcal and ‘of which sugars’ per bar, alongside the bar’s weight. For example, Eat Natural UK lists 220kcal and 10g sugars for its 40g Dark Chocolate & Peanut bar. | One bar may be my whole TV snack, so its per-bar figures matter more to me than a claim on the wrapper. |
| Ingredients and allergens | Check the current ingredient list, highlighted allergens and ‘may contain’ wording. The Food Standards Agency explains that precautionary allergen wording signals possible unintended presence. | I need a bar whose ingredients and allergen declarations fit what I can eat. |
| Dietary suitability | Check vegan or dairy-free labelling on the exact bar, then compare its protein, fibre, sugars and energy per serving. | If I choose a plant-based bar, I still want to compare its nutrition with the other bars I am considering. |
What is easy to overlook?
-
Assuming every protein-labelled bar has the same protein content
The stated amount varies by product: Nature Valley UK describes around 10g per 40g Protein Peanut & Chocolate bar, while Tesco lists 7.6g per 45g Nakd Peanut Butter Protein bar.
Compare grams of protein for the portion you will eat, together with its energy and other nutrition figures.
-
Reading ‘no added sugar’ as ‘no sugar’
A bar can contain sugars even when none have been added. Tesco lists 13g sugars per 45g Nakd Peanut Butter Protein bar.
Read the ‘of which sugars’ figure for the exact bar instead of relying on a front-of-pack phrase.
-
Missing an allergen warning
Nature Valley Protein Peanut & Chocolate contains peanuts, soya and milk, according to its Joybuy UK listing. Other bars can have different ingredients or precautionary warnings.
For an allergy or intolerance, check the current pack’s ingredients and ‘may contain’ statement before buying.
-
Assuming all plant-based bars have similar nutrition
TREK states 15g plant protein for its High Protein range; Tesco lists 7.6g protein per bar for Nakd Peanut Butter Protein. Those figures alone do not establish how the exact bars compare on sugars, energy or allergens.
Confirm dietary suitability first, then compare the nutrition panel for each flavour and serving size.

Questions about snack bars
Can a protein bar work as a TV-night snack?
Yes, if one bar is the portion you want and its nutrition suits what you are looking for. Compare protein, energy, sugars and fibre per bar rather than assuming a protein-labelled snack has a particular nutrition profile.
Does ‘no added sugar’ mean a bar contains no sugar?
No. Tesco lists 13g sugars per 45g Nakd Peanut Butter Protein bar, despite its no-added-sugar positioning. Check the ‘of which sugars’ figure for the bar you are buying.
Which allergen information matters when choosing a protein bar?
Read the current pack’s ingredients, highlighted allergens and ‘may contain’ statement. Nature Valley Protein Peanut & Chocolate, for example, contains peanuts, soya and milk according to Joybuy UK; other flavours and brands need their own checks.
Are protein snack bars always vegan?
No. TREK describes its bars as plant-based and Tesco labels Nakd Peanut Butter Protein vegan, but Nature Valley Protein Peanut & Chocolate contains milk. Check the suitability statement and ingredients of the exact bar.
