Who is this for?

Families comparing fat content

If fat content guides your choice, compare the total-fat figures per 100g. A lightly salted flavour name does not tell you whether a product meets the NHS low-fat threshold.

Households planning repeated snacks

Check the total weight as well as the number of bags. Six small portions and one sharing bag organise servings differently, even when both look suitable for a family shop.

Families balancing sweet and salty choices

If different people prefer different flavours, compare sugars and salt alongside fat. Check the exact pack’s allergen statement and whether its serving format works for your household.

What should you compare?

Start with the nutrition panel on a consistent per-100g basis, then check how the pack format fits the number of servings you plan.

Priority What to check Your needs
Total fat Compare total fat per 100g, not flavour wording. Sainsbury’s lists 17.4g per 100g for Propercorn Lightly Sea Salted and 20.4g for Propercorn Sweet & Salty; the NHS low-fat threshold is no more than 3g per 100g. I want to compare fat content without assuming that the lower-fat option in this pair is a low-fat food.
Sugars and salt Read both figures per 100g as well as fat. Sainsbury’s lists 11.3g sugars per 100g for Propercorn Sweet & Salty; ASDA Groceries lists 25g sugars and 2.0g salt per 100g for its Sweet & Salted bag. If I choose a sweet-and-salty flavour, I still want to see its sugar and salt figures before deciding.
Pack quantity Check total weight and the size of each portion. Sainsbury’s lists Propercorn Lightly Sea Salted as six 10g bags; ASDA Groceries suggests four servings from its 100g sharing bag. Will individually packed portions cover our planned snacks, or would serving from a larger bag work better?
Preparation and allergens Read the exact pack’s allergen statement. For microwave popcorn, check the appliance and supervision instructions; Sainsbury’s Propercorn microwave listing warns against leaving the microwave unattended. I need a format we can prepare as directed and an allergen statement suitable for the people eating it.

Common buying mistakes

  • Assuming popcorn is low fat

    The NHS low-fat threshold is no more than 3g fat per 100g. Sainsbury’s lists even its lightly sea-salted Propercorn multipack at 17.4g per 100g.

    Use the per-100g total-fat figure to compare products; treat “lightly salted” as a flavour description, not a fat measurement.

  • Checking fat but overlooking sugars and salt

    Two sweet-and-salty products can have different nutrition panels. ASDA Groceries lists 21g fat, 25g sugars and 2.0g salt per 100g for its 100g sharing bag.

    Compare all three figures on the packs you are considering, using the same per-100g basis.

  • Assuming a multipack will cover several family snacks

    Six individually wrapped portions do not necessarily add up to a large quantity: Propercorn Lightly Sea Salted 6x10g totals 60g.

    Count the servings you plan, then compare the total weight and portion size of each format.

  • Overlooking microwave instructions

    Sainsbury’s Propercorn microwave listing warns that the microwave must not be left unattended while the popcorn is prepared.

    Check that your appliance meets the pack instructions and that an adult can supervise preparation.

Brands and retailer ranges

These are product-specific points of comparison, not conclusions about every popcorn made or sold under each name.

Propercorn

The Sainsbury’s listings include ready-to-eat portion packs and a salted microwave format.

  • Sainsbury’s lists Lightly Sea Salted 6x10g at 17.4g fat per 100g and Sweet & Salty 6x14g at 20.4g fat per 100g.
  • The listed microwave product needs preparation and carries an instruction not to leave the microwave unattended.

ASDA

ASDA Groceries lists its own-brand Sweet & Salted Popcorn as a 100g sharing bag with four suggested servings.

  • A single bag can be served into separate portions.
  • Its panel lists 21g fat, 25g sugars and 2.0g salt per 100g; check all three if those figures affect your choice.

Tesco

Tesco Groceries lists its own-brand Sweet & Salted Popcorn as a 110g sharing bag containing four stated servings.

  • The 110g format offers a single bag from which to serve those portions.
  • The listed nutrition panel gives 26.2g fat and 22.6g sugars per 100g.

Tyrrells

Tesco Groceries lists Tyrrells sweet-and-salty popcorn in a 23g single bag and a six-pack format.

  • The stated pack formats allow a choice between one small bag and individually packed portions.
  • Both researched Tesco listings give 28.4g fat per 100g; check the exact pack’s salt figure, as the two listings differ.

Metcalfe’s

DDC Foods Ltd lists Metcalfe’s Sea Salt Popcorn in a trade case of 24x17g bags.

  • The case format divides the total quantity into 24 stated packs.
  • The trade listing gives 22.3g fat and 0.8g salt per 100g; check whether this case format is suitable for your household purchase.

Frequently asked questions

Is popcorn with less fat than another pack necessarily low fat?

No. The NHS defines low-fat food as containing no more than 3g fat per 100g. Sainsbury’s lists Propercorn Lightly Sea Salted at 17.4g per 100g: less than the sweet-and-salty retailer examples compared here, but above that low-fat threshold.

Does “lightly salted” tell me how much fat is in the popcorn?

No. Check the total-fat figure per 100g rather than using flavour wording as a nutrition measure. Read sugars and salt on the same panel if they also affect your choice.

Should a large family choose portion packs or a sharing bag?

Choose the format around the servings you plan. Sainsbury’s lists Propercorn multipacks of six 10g or six 14g bags, while ASDA Groceries suggests four servings from its 100g sharing bag. Compare total quantity as well as the stated serving size.

Can children prepare microwave popcorn on their own?

Follow the instructions on the exact product. Sainsbury’s Propercorn microwave listing says not to leave the microwave or children unattended while popping, so arrange adult supervision rather than treating its bags as a ready-to-eat snack.

Is a vegan or gluten-free description enough to assess allergies?

No. Check the exact pack’s allergen and precautionary statements for the person eating it. The Propercorn Lightly Sea Salted product information describes it as vegan and gluten free but also states that it is made in a factory handling milk.
