Night-shift workers comparing pack calories
If you take a savoury snack to work, the calories and weight of the bag you expect to finish are more useful than a general description such as ‘hand-cooked’.
Who this choice matters to
Crisp eaters open to potato snacks
A baked or formed potato snack gives you another crisp-style option, provided you do not specifically want conventional sliced-potato crisps. Check the ingredients and pack size as well as the calories.
Night workers checking salt
If several packaged savoury foods feature in your shift, compare the salt figure on each pack rather than assuming a smaller or baked snack contains little salt.
What to check before choosing
Decide whether you want sliced-potato crisps or are happy with a crisp-style alternative, then compare the nutrition for the portion you will actually eat.
| Priority | What to check | Your needs |
|---|---|---|
| Calories per pack | Compare both kcal and bag weight. Seabrook lists 82 kcal per 18g bag of Sea Salted Crunchies and 159 kcal per 31.8g bag of Sea Salt & Vinegar crisps; Walkers lists 96 kcal per 22g Oven Baked Sea Salt pack. | For a short break, I want to know the calories in the whole bag I am likely to eat, not just a figure per 100g. |
| Salt | Read the salt value for the exact flavour and portion. Seabrook lists 0.3g per Crunchies bag and 0.8g per Sea Salt & Vinegar bag; Walkers lists 0.19g per Oven Baked Sea Salt pack. | I may have other savoury foods during the shift, so I want to check how this pack fits with them. |
| Product type | Check whether the label says potato crisps, potato snacks or another food. Confirm ingredients and any dietary suitability on the particular flavour rather than assuming they apply across a brand. | If sliced-potato texture matters to me, a formed potato snack or a lentil crisp is not the same choice. |
| Portion format | Check whether the stated nutrition covers an individual bag, one serving from a larger pack or the entire pack. Compare the amount you intend to take to work. | An individual bag is straightforward for my break; with a sharing pack, I would need to portion it myself. |
| Food for the shift | Consider what else you will take for a longer break. The British Dietetic Association’s shift-work guidance discusses planning meals and nutrient-dense snacks that can be transported and stored at work. | I can choose crisps as a small savoury snack without treating the bag as my whole shift meal. |
Common buying mistakes
-
Assuming every crisp-style snack is a potato crisp
Seabrook describes Sea Salted Crunchies as potato snacks, while its Sea Salt & Vinegar product is labelled potato crisps. Walkers Oven Baked Sea Salt is made from potato flakes and starch, so the products are not interchangeable if you want sliced-potato crisps.
Choose the product type first, then compare the exact flavours and pack labels within the options you would eat.
-
Comparing calories per 100g but ignoring bag size
The individual packs compared here range from 18g to 31.8g. A per-100g figure alone does not tell you the calories in the bag you finish on a break.
Compare calories and salt for the whole individual pack, or for the portion you plan to take from a larger bag.
-
Using a small crisp bag in place of a planned meal
A portioned bag answers a different need from a meal during a long shift. The British Dietetic Association’s shift-work guidance discusses planning transportable meals and nutrient-dense snacks.
If you need a more substantial break, plan other food separately rather than relying on the crisp bag alone.
Relevant brand references
These examples show why the exact product and portion matter more than the brand name alone.
Walkers
Walkers lists 96 kcal and 0.19g salt for a 22g pack of Oven Baked Sea Salt.
- An individual pack makes its stated portion easy to compare with other snacks.
- This product uses potato flakes and starch rather than conventional sliced potatoes; check the exact flavour’s ingredients and allergens.
Seabrook
Seabrook lists 82 kcal for an 18g bag of Sea Salted Crunchies and 159 kcal for a 31.8g bag of Sea Salt & Vinegar crisps.
- The two named products offer a choice between a potato snack and conventional potato crisps.
- Their bag sizes and salt values differ: Seabrook lists 0.3g and 0.8g salt per bag respectively.
Tyrrells
Tyrrells lists 140–141 kcal per 30g serving for the lentil crisp flavours covered by its nutrition information.
- A lentil-based option is worth considering if potato content is not essential to your choice.
- A 30g serving is not directly comparable with an 18g or 22g individual bag without accounting for portion size.
KETTLE Chips
KETTLE Chips lists 513 kcal and 1.6g salt per 100g for Sea Salt & Balsamic Vinegar potato crisps.
- The brand states that this particular flavour is suitable for vegans and vegetarians and is gluten-free.
- Use the portion you intend to eat to assess a larger pack; the per-100g figure is not a single-pack value.
Pipers
Pipers lists 532 kcal and 0.94g salt per 100g for Anglesey Sea Salt potato crisps.
- The listed ingredients for this flavour are potatoes, sunflower oil and Anglesey sea salt.
- Check your intended portion before comparing it with the smaller individual bags above.
Real Crisps
REAL Hand Cooked Crisps describes its Strong Cheddar & Onion product as potato crisps made with vegetable oils.
- It is a conventional potato-crisp option for shoppers who prefer that product type.
- The listed cheddar-and-onion flavouring contains milk ingredients; check the pack for the portion’s nutrition and full allergen information.

Walkers Oven Baked Cheese & Onion Crisps Flavour, 6 x 22g
Six individual 22g bags suit a break where you want to take one portion rather than a sharing pack. Check this Cheese & Onion flavour’s own calories, salt, ingredients and allergens; the Sea Salt flavour’s figures do not establish them.

Questions about night-shift crisps
Can a bag of crisps replace a night-shift meal?
Treat a small bag as a savoury snack rather than your planned meal. The British Dietetic Association’s shift-work guidance discusses preparing meals and nutrient-dense snacks that you can transport and store at work; plan more substantial food separately if you need it during a long shift.
Which of the named potato-based single bags has fewer calories?
Seabrook lists 82 kcal per 18g bag of Sea Salted Crunchies, compared with Walkers’ 96 kcal per 22g pack of Oven Baked Sea Salt. Crunchies are labelled potato snacks, not conventional potato crisps, and the bags are different sizes.
Does ‘baked’ tell me how much salt is in the pack?
No; check the salt figure for the exact product and flavour. Walkers lists 0.19g salt in a 22g pack of Oven Baked Sea Salt, but that figure should not be applied to other flavours or products.
What does the NHS say about salt for adults?
The NHS advises adults to have no more than 6g of salt a day, including salt already in food and salt added during or after cooking. A crisp pack’s salt value is one part of that daily total; follow individual clinical advice if you have been given it.
