Students comparing fat content
If you want popcorn with a lecture-day lunch, compare fat per 100g across products, then check the amount in the pack you expect to eat. A smaller pack is not necessarily a low-fat product.
Who is this for?
Students planning a single snack portion
A 10g or 14g sachet gives you a defined amount to carry between classes. With a sharing bag, decide how much to take before leaving rather than treating its stated serving as the whole bag.
Students checking ingredients and allergens
If dietary requirements affect your choice, read the ingredients and precautionary allergen wording on the exact pack. Check sugars and salt alongside fat when comparing flavours.
What should you check?
Start with fat per 100g for a like-for-like comparison, then use pack weight and the stated serving to decide how much popcorn to take to campus.
| Priority | What to check | Your needs |
|---|---|---|
| Total fat | Compare total fat per 100g across similar popcorn. The NHS defines low fat as 3g or less per 100g; a small pack does not change that classification. | I want to compare the popcorn itself, not mistake a small serving for a low-fat recipe. |
| Portion size | Check the weight of an individual sachet or the number and size of servings in a sharing bag. Tesco Groceries lists Propercorn Sea Salted at 1.7g fat per 10g sachet; ASDA Groceries describes its 70g Sea Salted bag as approximately three servings. | One sachet is easy to put in my bag; if I take a sharing pack, I would rather portion it before a lecture break. |
| Sugars and salt | Read both figures per 100g, then check the portion you plan to eat. Tesco Groceries lists 11.3g sugars per 100g for Propercorn Sweet & Salty 6 x 14g and 1.09g salt per 100g for Propercorn Sea Salted 6 x 10g. | Flavour matters to me, but I also want to see what changes when I choose a sweet-and-salty recipe. |
| Dietary information | Check the ingredients, dietary statements and precautionary allergen wording on the exact pack. Do not treat a flavour name as an ingredient or allergen declaration. | I need to know whether the pack suits my dietary requirements before I take it to university. |
Common buying mistakes
-
Assuming a small pack or a name such as “skinny” means low fat
Pack size affects how much you eat, while a low-fat classification depends on fat per 100g. Tesco Groceries lists Propercorn Sea Salted 6 x 10g at 17.4g fat per 100g; the NHS low-fat threshold is 3g or less per 100g.
Compare the per-100g figure first, then check the fat in the portion you intend to eat.
-
Treating a sharing bag as one stated serving
ASDA Groceries describes its 70g Propercorn Sea Salted bag as approximately three servings. Tesco Groceries gives a 20g quarter-pack serving for Metcalfe's Sweet 'N Salt 80g bag. Finishing either bag means eating more than one stated serving.
Take an individual sachet or put your intended portion from a sharing bag into a separate container.
-
Checking fat but overlooking the rest of the label
Sweet-and-salty products can have different sugar and salt figures from sea-salted ones. Ingredients and precautionary allergen wording also matter when a snack must meet a dietary requirement.
Read sugars, salt, ingredients and allergen information on the exact pack before buying.
Brand and retailer references
These references describe particular popcorn listings and formats, not a ranking of everything each brand or retailer sells.
Propercorn
Tesco Groceries lists Sea Salted and Sweet & Salty popcorn in individual multipacks; ASDA Groceries also lists a 70g Sea Salted sharing bag.
- Tesco Groceries lists 1.7g fat in each 10g Sea Salted sachet, making the stated portion straightforward to compare with its per-100g figure.
- The Sea Salted multipack has 17.4g fat per 100g, above the NHS low-fat threshold of 3g or less per 100g. Tesco Groceries lists Sweet & Salty at 20.4g per 100g.
Metcalfe's
Tesco Groceries lists Metcalfe's Sweet 'N Salt popcorn in an 80g sharing bag.
- The sharing format allows you to divide the bag into portions before taking it to campus.
- Tesco Groceries lists 23.8g fat and 18.1g sugars per 100g for this product; its stated serving is 20g, not the full bag.
Tesco
Tesco Groceries lists its own-label sweet, sweet-and-salted and salted popcorn alongside branded products.
- The different flavours and formats give you pack labels to compare when choosing a snack.
- Compare nutrition on the specific own-label pack rather than applying figures from a branded product to it.
Asda

Questions about choosing popcorn
Is ready-to-eat popcorn automatically low fat?
No. The NHS defines low fat as 3g fat or less per 100g. Tesco Groceries lists Propercorn Sea Salted 6 x 10g at 17.4g per 100g, so its small sachet does not make it a low-fat product. Check the figure for the exact popcorn you are buying.
Should I compare popcorn per pack or per 100g?
Use both figures: per 100g compares products on the same basis, while per pack helps you assess an individual sachet you intend to finish. Tesco Groceries lists 1.7g fat per 10g pack for Propercorn Sea Salted. For a sharing bag, check its stated serving size and how much you actually plan to take.
Does sweet-and-salty popcorn change the fat comparison?
It does for the Propercorn multipacks listed by Tesco Groceries: Sweet & Salty 6 x 14g has 20.4g fat per 100g, compared with 17.4g per 100g for Sea Salted 6 x 10g. The Sweet & Salty product also lists 11.3g sugars per 100g. Compare other recipes by their own labels rather than assuming the same difference applies.
What should I check if I have a dietary requirement?
Read the ingredients, dietary statements and precautionary allergen wording on the exact pack you intend to take to university. Check the current pack even if you have bought the same flavour before.
