Late-night snackers comparing fat
If reducing fat matters to you, a lighter-sounding name is not enough. Compare the per-100g figure across products, then look at the amount in the pack you expect to eat.
Who is this choice for?
Shoppers planning a small portion
An individual pack gives you a set amount without measuring from a larger bag. Sainsbury’s lists Propercorn Lightly Sea Salted in 10g packs; the reviewed Asda products come in sharing bags.
People choosing between savoury and sweet
Flavour can change the comparison. Asda lists less than 0.5g sugars per 100g for its Salted Popcorn, compared with 25g sugars and 2.0g salt per 100g for its Sweet & Salted Popcorn.
What should you compare?
Start with the per-100g nutrition panel to compare recipes, then use the pack size to judge the amount you are likely to eat.
| Priority | What to check | Your needs |
|---|---|---|
| Total fat | Compare total fat per 100g on the same basis. UK Department of Health and Social Care guidance sets no more than 3g fat per 100g for a low-fat claim on solid food; do not infer that claim from a product name. | I’m looking to reduce fat, so I want to know how the popcorn itself compares before considering pack size. |
| Portion size | Check the weight of an individual pack or the suggested serving of a larger bag. Use that amount alongside the per-100g figures. | A set small pack may suit me better than deciding how much to take from a sharing bag late at night. |
| Sugars and salt | Read both figures per 100g, especially when comparing salted with sweet-and-salted popcorn. Asda lists 25g sugars and 2.0g salt per 100g for its Sweet & Salted variety. | If I want a sweet flavour, I also want to see what changes besides the fat figure. |
| Ingredients and allergens | Read the current pack’s ingredients and allergen information. The reviewed Propercorn Lightly Sea Salted multipack is labelled as made in a factory that handles milk. | With a food allergy or intolerance, I need the information for the packet I will eat. |
What can be misleading?
-
Treating “skinny” or “lightly salted” as proof of low fat
Seasoning and brand wording do not tell you the total fat content. Sainsbury’s lists Propercorn Lightly Sea Salted at 17.4g fat per 100g, above the UK Department of Health and Social Care’s low-fat claim threshold of no more than 3g per 100g for solid foods.
Check the fat figure per 100g and assess any nutrition claim separately from the flavour name.
-
Choosing on fat alone
Asda’s Sweet & Salted Popcorn lists less fat per 100g than its Salted Popcorn, but its label also lists 25g sugars and 2.0g salt per 100g.
Compare fat, sugars and salt together when deciding between flavours.
-
Comparing different pack sizes by the pack alone
A smaller pack contains less popcorn, so its per-pack figures do not by themselves show how its recipe compares with a sharing bag.
Compare products per 100g first, then check the weight of the portion you plan to eat.
-
Using an online listing instead of the packet for allergens
The reviewed Propercorn Lightly Sea Salted multipack carries a factory milk-handling statement, which may matter to someone with a milk allergy.
Read the ingredient and allergen information on the current packet before eating.
Relevant brand and retailer references
These references describe specific popcorn listings or ranges, not a ranking of the brands or a list of everything sold on Joybuy.
Propercorn
Sainsbury’s lists a Lightly Sea Salted multipack containing six 10g packs.
- The listed multipack has 17.4g fat and 0.6g sugars per 100g, with 1.7g fat per 10g pack.
- It does not meet the UK low-fat claim threshold for solid foods. Its listing says it is made in a factory that handles milk.
Asda
Asda lists both Salted and Sweet & Salted popcorn in sharing bags.
- The two listings allow a direct per-100g comparison: 26g fat and less than 0.5g sugars for Salted, versus 21g fat and 25g sugars for Sweet & Salted.
- Neither listed product meets the UK low-fat claim threshold for solid foods; check the serving you take from either bag.
Metcalfe’s
Tesco’s listing identifies Metcalfe’s Skinny Popcorn Sweet ’N Salt as a ready-to-eat sweet-and-salty option.
- “Skinny” is not a substitute for checking the current fat-per-100g figure when that is your buying priority.
Tesco
Tesco Groceries lists own-label salted, sweet and sweet-and-salted popcorn alongside branded and microwave options.
- The different formats give shoppers a choice between ready-to-eat and microwave popcorn.
- Compare the nutrition panel of the particular product and format rather than treating the range as one recipe.
Tyrrells
Tyrrells’ range page lists potato crisps, Furrows crisps and lentil crisps.
- For this popcorn decision, check for a specific popcorn product and its nutrition panel rather than choosing by brand name.

Propercorn Lightly Sea Salted Popcorn 6 x 10g
The individual 10g packs make it straightforward to choose a set amount. Sainsbury’s lists this multipack variant at 17.4g fat and 0.6g sugars per 100g; it does not meet the UK low-fat claim threshold for solid foods. Check the packet’s allergen information: the reviewed listing says it is made in a factory that handles milk.

Propercorn Lightly Sea Salted 70g
The 70g bag lets you serve your own amount rather than opening an individual 10g pack. Check its current per-100g nutrition panel when comparing fat, and read the packet’s allergen information before eating.
No image available
Propercorn Sweet & Salty 6 x 14g
Each 14g pack provides a set portion of sweet-and-salty popcorn. If reducing fat is your main aim, compare its current fat, sugars and salt figures per 100g with the lightly salted option rather than choosing by pack size alone.
No image available
Butterkist Sweet & Salty Popcorn 6 x 12g
The six 12g packs offer individually sized portions. To decide whether this sweet-and-salty variety fits your priorities, compare fat, sugars and salt per 100g on its current pack with the other options.
Questions about choosing popcorn
Does “lightly salted” mean low fat?
No. “Lightly salted” describes the flavour, not the total fat content. Sainsbury’s lists Propercorn Lightly Sea Salted at 17.4g fat per 100g, so check the nutrition panel rather than relying on the name.
What does a low-fat claim mean for packaged popcorn?
For solid food, UK Department of Health and Social Care guidance sets a low-fat claim threshold of no more than 3g fat per 100g. A product with less fat than another popcorn does not necessarily meet that threshold; compare its current label before treating it as low fat.
Should I compare per-100g or per-pack figures?
Use per-100g figures to compare popcorn recipes, then use the pack or serving size to consider the amount you will eat. A 10g individual pack and a sharing bag are different amounts, even when both labels show per-pack information.
What if I have a food allergy or intolerance?
Check the ingredients and allergen information on the current packet before eating. The reviewed Propercorn Lightly Sea Salted multipack listing says it is made in a factory that handles milk; use the information on the pack you have, rather than a flavour name, to assess that warning.
