Late-night snackers
If you want one ready-to-eat savoury bag, check both its weight and how many bags you are buying. A case of individual portions is not the same purchase as one grab bag.
Who is choosing?
People deciding on supper
If crisps might be your supper rather than a snack, consider what else you will eat across the day. The NHS Eatwell Guide advises looking at food-group balance over a day or week.
Label-conscious shoppers
If salt, portion size or allergens affect your choice, compare the exact flavour and pack. A short ingredient list does not rule out a precautionary allergy statement.
What should you check?
Start with the quantity you are buying, then compare the flavours and labels of bags that fit the occasion.
| Priority | What to check | Your needs |
|---|---|---|
| Bag size | Read the net weight of each bag and the number of bags in the sale unit. Check whether nutrition is stated per bag, per serving or per 100 g. | I want one snack, not a sharing bag or a case of bags. |
| Flavour and texture | Check the named flavour, ingredients and described style, such as hand-cooked or ridged. Neither style alone establishes a nutrition advantage. | A plain salted flavour might suit me, or I might prefer seasoning or a ridged texture. |
| Nutrition | Compare salt on the same per-100 g basis, then check the amount per bag. The NHS food-label guide describes more than 1.5 g salt per 100 g as high. | If I eat the whole bag, I want to know what that bag contains, not just what the per-100 g figures say. |
| Ingredients and allergens | Read the exact pack’s ingredients, declared allergens and precautionary statements. Tyrrells says its Lightly Sea Salted crisps may contain milk. | For an allergy or dietary restriction, I need to check the particular flavour rather than rely on its name. |
| Snack or supper | Decide whether a bag is the snack you want or whether you also need other food. The NHS Eatwell Guide considers overall balance across a day or week. | Am I looking for something crunchy, or am I planning the food I will have for supper? |
Common buying mistakes
-
Confusing individual bags with a single-bag purchase
REAL sells its Sea Salt crisps as a case of 24 individual 35 g bags. Tyrrells lists a 40 g size of Lightly Sea Salted crisps; those descriptions represent different quantities to buy.
Check both the weight of each bag and the number of bags in the sale unit.
A case means taking home more bags than you need for one supper.
-
Using “lightly salted” or “hand-cooked” as the nutrition comparison
Salt figures depend on the exact flavour, while the amount in the bag depends on its size. Kettle Chips lists 0.7 g salt per 100 g for Lightly Salted and 1.6 g per 100 g for Sea Salt & Balsamic Vinegar.
Compare the exact variants per 100 g, then read the nutrition information for the amount you intend to eat.
-
Assuming a short ingredient list rules out an allergy warning
Tyrrells lists potatoes, sunflower oil and sea salt as ingredients for Lightly Sea Salted, alongside a “May contain Milk” warning.
If an allergy applies, read both the ingredients and precautionary information on the exact pack.
Brand and style references
These examples help distinguish flavours and formats; a statement about one variant should not be assumed to cover a brand’s whole range.
Walkers
A potato-crisp option with published information for Ready Salted.
- Walkers lists 0.34 g salt per 25 g serving of Ready Salted and describes that product as suitable for vegetarians.
- Check the weight and label of the particular bag; the 25 g serving figure does not describe every Walkers pack.
Tyrrells
Hand-cooked potato crisps, including Lightly Sea Salted in a listed 40 g size.
- Tyrrells lists potatoes, sunflower oil and sea salt as ingredients for Lightly Sea Salted.
- The same flavour carries a “May contain Milk” statement; “lightly” does not by itself compare its salt content with another flavour.
Kettle Chips
A hand-cooked range with plain and seasoned flavours.
- Kettle Chips lists 0.7 g salt per 100 g for Lightly Salted.
- Its Sea Salt & Balsamic Vinegar figure is 1.6 g per 100 g. Compare the exact flavour rather than applying either figure across the range.
Seabrook
Crinkle-cut crisps with a Sea Salted variant.
- Seabrook describes Sea Salted as suitable for vegetarians and vegans and gives nutrition per 31.8 g bag.
- Those details concern Sea Salted, not every Seabrook flavour.
McCoy's
Ridged crisps with seasoned flavours, including Flame Grilled Steak.
- The McCoy's range identifies a ridged style for shoppers choosing by texture.
- Check the exact flavour’s ingredients, bag weight and nutrition before choosing.
REAL Crisps
Hand-cooked crisps offered by the manufacturer in cases of individual bags.
- REAL lists Sea Salt as a case of 24 individual 35 g bags.
- That case listing should not be mistaken for a purchase of just one 35 g bag.

Frequently asked questions
Can a bag of crisps be my late-night supper?
You can choose a bag as a snack, but consider it alongside what else you eat. The NHS Eatwell Guide advises aiming for balance over a day or week, rather than expecting every meal to provide it.
How do I compare salt in different-sized bags?
Compare salt per 100 g first, then check the amount in the bag you intend to eat. The NHS food-label guide describes more than 1.5 g salt per 100 g as high; that per-100 g figure is not the amount in every bag.
What should I check if someone has a food allergy?
Read the exact pack’s ingredients, allergen information and any precautionary statement. Tyrrells Lightly Sea Salted, for example, lists three ingredients but also says “May contain Milk”; a plain-sounding flavour name is not an allergy check.
Is a case of small bags the same as one grab bag?
No. REAL lists Sea Salt as 24 individual 35 g bags in one case. Check both the number of bags and the weight of each before choosing a sale unit for one snack.
How should I store an unopened bag?
Follow the instructions on the particular pack. Tyrrells recommends a cool, dry place for its Lightly Sea Salted crisps; check other products’ labels for their own directions.
