For a lower-total-fat choice among the Tesco Groceries products compared here, Propercorn Sea Salted lists 17.4g fat per 100g, against 21.4g and 23.8g for the two Metcalfe's flavours. None meets the NHS low-fat threshold of 3g or less per 100g. For a working-from-home lunch, compare labels per 100g first, then choose a portion size that suits you and check sugars, salt and allergen information.
If an open sharing bag makes it harder to decide how much to have with lunch, an individually packed serving gives you a clear stopping point. Tesco Groceries lists 44 kcal for each 10g bag in the Propercorn Sea Salted multipack.
Total fat and saturated fat are separate figures. The NHS defines low fat as 3g or less per 100g and low saturated fat as 1.5g or less per 100g, so check which measure matters to your comparison.
Sweet, salty and caramel flavours can have different sugar and salt figures. Compare the exact flavour's nutrition panel, ingredients and allergen statement rather than assuming the information applies to every popcorn in a range.
Start with total fat per 100g to compare packs on the same basis. Then check the serving you would actually eat and the other label details that matter to you.
| Priority | What to check | Your needs |
|---|---|---|
| Total fat and saturates | Compare both figures per 100g. The NHS low-fat threshold is 3g total fat or less per 100g; its low-saturated-fat threshold is 1.5g saturates or less per 100g. A lower saturates figure does not establish low total fat. | I want to know whether I am comparing total fat, saturates or both—not rely on wording such as “skinny” to answer that question. |
| Portion and pack | Check the weight of one bag or declared serving, then read its per-serving values alongside the per-100g panel. Tesco Groceries lists the Propercorn Sea Salted multipack as 6 x 10g. | A separate bag gives me a defined quantity for a work break. If I choose a sharing bag, I would rather put my intended portion in a bowl. |
| Flavour details | Compare sugars and salt per 100g, as well as the ingredients and allergen statement for the exact flavour. Tesco Groceries lists 18.1g sugars and 1.3g salt per 100g for Metcalfe's Sweet 'N Salt. | I may prefer a sweet-and-salty flavour, but I still want to see how its label compares with a savoury option and check ingredients that matter to me. |
A small bag can have a modest per-pack figure while its per-100g total fat remains above the NHS low-fat threshold of 3g or less. Tesco Groceries lists 17.4g fat per 100g for Propercorn Sea Salted, despite its 10g multipack portions.
Use per-100g total fat for the product comparison and per-pack figures to decide on your serving.
Separate 10g Propercorn bags and a larger open bag offer different ways to manage a lunch-side serving. Tesco Groceries lists four 20g portions for Metcalfe's 80g Sweet 'N Salt bag.
If you choose a sharing bag, put the quantity you intend to eat in a bowl before returning to work.
Flavour changes the comparison: Tesco Groceries lists 21.0g sugars per 100g for Metcalfe's Salted Caramel and 1.09g salt per 100g for Propercorn Sea Salted. Ingredients and allergen statements also need checking for the exact pack.
Read sugars, salt, ingredients and allergens alongside fat and saturates, particularly when switching flavours.
These figures describe the named popcorn products, not everything each brand makes.
Tesco Groceries lists Sea Salted popcorn in a 6 x 10g multipack and a 70g bag. The multipack offers separately packed portions for a desk lunch.
Tesco Groceries lists Metcalfe's Sweet 'N Salt 80g and Salted Caramel 75g as two distinct flavoured popcorn options.
Tesco Groceries lists Sweet & Salt popcorn in a single 23g bag, rather than the sharing-bag format of the Metcalfe's examples above.
These Propercorn options cover separately packed savoury and sweet-and-salty popcorn, plus a 90g sweet-and-salty bag. Use their pack formats and current nutrition labels to decide what fits your lunch.

Separate 10g bags provide a defined lunch-side portion. Joybuy lists 44 kcal per 10g bag and, per 100g, 17.4g total fat, 1.5g saturates and 1.09g salt. The total-fat figure exceeds the NHS low-fat threshold of 3g or less per 100g; check the current pack's allergen statement if relevant.

Six separate 14g bags offer a defined pack size if you prefer sweet-and-salty popcorn with lunch. Compare total fat, saturates, sugars and salt per 100g on the current pack before choosing it for a lower-fat aim; check the milk statement if relevant.

If you choose this 90g bag for a desk lunch, put your intended serving in a bowl rather than treating the whole bag as one portion. Check the pack's serving information, per-100g fat, saturates, sugars and salt, and its milk statement where relevant.
No. A comparative claim and a low-fat classification answer different questions. The NHS defines low fat as 3g total fat or less per 100g; Tesco Groceries lists 17.4g to 28.4g total fat per 100g across the Propercorn, Metcalfe's and Tyrrells products discussed here. Check the figure for the exact pack rather than relying on wording on its front.
Use per 100g to compare different products, then use the pack or serving figure to plan how much to have. For example, Tesco Groceries lists 44 kcal for a 10g Propercorn Sea Salted multipack bag, while its 70g bag is a different format.
Check saturates, sugars, salt, ingredients and allergens for the exact flavour as well as total fat. Tesco Groceries lists 18.1g sugars and 1.3g salt per 100g for Metcalfe's Sweet 'N Salt, illustrating why a flavour choice needs more than one label figure.
