Snackers comparing total fat
If lower total fat is your priority, compare the per-100g figures rather than relying on words such as ‘skinny’ or ‘lightly salted’. Then check the fat in the portion you expect to eat.
Who is this choice for?
People who prefer a defined portion
An individual 10g or 17g pouch gives you one pack to open at a time. With a larger sharing bag, decide how much to serve before settling down to your afternoon snack.
Microwave-popcorn buyers
Microwave popcorn suits a snack you can prepare at home, provided you can follow that product’s cooking instructions and stay nearby. Check how many servings the prepared bag contains rather than treating the whole bag as one portion.
What should you compare?
Start with the nutrient you actually want to compare, then consider the serving size and preparation the snack requires.
| Priority | What to check | Your needs |
|---|---|---|
| Total fat | Read total fat per 100g on comparable products. Check whether a reduction claim refers to total fat or specifically to saturated fat. | I want to compare total fat, not mistake a flavour description or a saturated-fat claim for a total-fat claim. Tesco’s Metcalfe’s Salted Caramel listing states at least 30% less saturated fat than average salted-caramel-style popcorn, while listing 21.4g total fat per 100g. |
| Comparable figures | Use the same per-100g measure across ready-to-eat packs, then read the per-pack or per-serving figure. Sainsbury’s lists 17.4g fat per 100g for Propercorn Lightly Sea Salted 6 x 10g; Tesco lists 19.2g for Metcalfe’s Sweet & Salt 6 x 17g. | A mini pouch and a sharing bag are different amounts of popcorn. I want a fair product comparison before deciding how much to serve. |
| Portion format | Check the weight of an individual pouch or the suggested servings in a larger bag. Tesco lists approximately four servings in its 85g salted bag; Asda suggests three in its 80g salted bag. | For a desk snack, I may prefer opening one small pouch. If I choose a sharing bag, I can serve the amount I intend to eat. |
| Other label details | Read salt, ingredients, allergen advice and dietary statements on the current pack. For microwave popcorn, also check the equipment and cooking instructions for that product. | Fat is not my only consideration: the ingredients need to suit me, and I need time and equipment to prepare a microwave bag safely. |
Common buying mistakes
-
Reading ‘skinny’ or ‘lightly salted’ as a total-fat claim
Those words do not tell you the product’s total fat. Tesco’s Metcalfe’s Salted Caramel listing compares saturated fat with average salted-caramel-style popcorn and separately lists 21.4g total fat per 100g.
If total fat is your criterion, compare the total-fat line per 100g and read precisely what any reduction claim measures.
-
Comparing a mini pouch with an entire sharing bag
Pack sizes change the amount eaten: Tesco’s 85g salted bag contains approximately four suggested servings, while Asda suggests three servings in its 80g bag.
Compare products per 100g first, then use the pack or serving figures to choose an amount that fits your snack.
-
Looking only at fat
Salt, ingredients and allergen advice can affect whether a particular popcorn is suitable. Metcalfe’s Salted Caramel, for example, contains milk ingredients.
Read the current label for the exact variant before buying, particularly when an ingredient or allergen matters to you.
-
Leaving microwave popcorn unattended
Sainsbury’s instructions for Propercorn microwave popcorn warn that leaving the microwave unattended may lead to burning or fire.
Follow the instructions on the bag, use the specified microwave arrangement and stay nearby while it pops.
Relevant brand references
These examples illustrate different pack formats and label figures; a brand name alone does not establish a fat claim for every product it makes.
Propercorn
Sainsbury’s lists both a ready-to-eat Lightly Sea Salted 6 x 10g multipack and a separately prepared salted microwave product.
- The 10g pouch lists 1.7g fat per pouch and 17.4g per 100g.
- The microwave product is a different format: Sainsbury’s lists approximately three servings per bag, so its serving figures should not be treated as figures for the multipack.
Metcalfe’s
Tesco lists Metcalfe’s Sweet & Salt 6 x 17g and Salted Caramel 75g with different total-fat figures.
- The Sweet & Salt listing gives 19.2g total fat per 100g and 3.3g per 17g pack.
- The Salted Caramel listing’s claim of at least 30% less saturated fat than average salted-caramel-style popcorn concerns saturated fat, not its listed 21.4g total fat per 100g.
Tesco
Tesco’s own-label Salted Popcorn comes in an 85g sharing bag with approximately four suggested servings.
- The listing provides both per-100g and per-21g-serving fat figures.
- Its stated 31.2g fat per 100g is above the Propercorn Lightly Sea Salted multipack’s 17.4g per 100g in this ready-to-eat comparison.
Asda
Asda’s own-label Salted Popcorn is an 80g sharing bag with three suggested 25g servings.
- The listing states 6.5g fat per suggested 25g serving.
- At 26g total fat per 100g on Asda’s listing, it differs from a pre-portioned 10g pouch in both its per-100g figure and the amount opened at once.

Questions about choosing popcorn
Does a reduced-saturated-fat claim mean lower total fat?
No: saturated fat and total fat are different figures. Tesco’s Metcalfe’s Salted Caramel listing states at least 30% less saturated fat than average salted-caramel-style popcorn, while listing 21.4g total fat per 100g. If total fat matters to you, read that line separately.
Which of the compared ready-to-eat packs lists the least total fat?
Among four ready-to-eat products listed by Sainsbury’s, Tesco and Asda, Propercorn Lightly Sea Salted 6 x 10g has the lowest stated figure at 17.4g fat per 100g. The other listed figures are 19.2g for Metcalfe’s Sweet & Salt, 26g for Asda Salted Popcorn and 31.2g for Tesco Salted Popcorn, each per 100g. This is a comparison of those four products, not a claim about every popcorn option.
Should I use the per-pack or per-100g figure?
Use per 100g to compare products on the same basis, then use the per-pack or per-serving figure to consider the amount you intend to eat. Sainsbury’s lists 1.7g fat in a Propercorn Lightly Sea Salted 10g pouch; Tesco lists 6.6g in a suggested 21g serving of its salted popcorn.
What changes when I choose microwave popcorn?
You need to prepare it according to the particular bag’s instructions and consider how much of the prepared bag to serve. Sainsbury’s lists approximately three servings per bag for Propercorn microwave popcorn and warns against leaving the microwave unattended because of burning or fire risk.
What should I check if ingredients or allergens matter?
Read the current packaging for the exact variant’s ingredients and allergen advice. Metcalfe’s Salted Caramel contains milk ingredients, while the Propercorn ready-to-eat multipack carries a milk-handling warning; those are different statements and should not be applied to other variants without checking their labels.
