Choose popcorn for the portion and flavour you want, rather than relying on it as the main protein component of a snack. Myprotein lists 3.8g protein and 3.7g fat per 21g bag; if keeping total fat lower matters more, compare both figures per 100g and for the amount you will eat. A reduced-saturated-fat claim does not, by itself, tell you either figure.
If you want popcorn as part of a high-protein eating plan, check the protein in the portion you will actually eat. The labelled servings of the Myprotein, Propercorn microwave and Metcalfe's products discussed here provide 3.8g, 2.1g and 1.4g respectively.
If you are choosing between microwave and ready-to-eat popcorn, use total fat per 100g for a like-for-like comparison, then check the fat in your portion. A claim about reduced saturated fat answers a different question.
If milk or soya matters to you, check the exact flavour and pack. Myprotein lists whey protein isolate and soya lecithin, while Tesco Groceries lists a possible milk warning for Propercorn Salted Microwave Popcorn.
Start with the amount you expect to eat, then compare protein and total fat for that amount as well as per 100g.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per portion | Check protein per 100g and per labelled serving. Myprotein lists 18g per 100g and 3.8g per 21g bag; Tesco Groceries lists 2.1g per prepared 20g serving of Propercorn Salted Microwave Popcorn. | I want to know how much protein my snack portion contributes, rather than judging it by a protein-focused product name. |
| Total fat and claim wording | Compare total fat per 100g and per portion. Tesco Groceries lists 16g per 100g for Propercorn Salted Microwave Popcorn and 21.4g for Metcalfe's Salted Caramel; the Metcalfe's comparison concerns saturated fat, not total fat. | If keeping total fat lower is my priority, I need the total-fat figure for the amount I plan to eat. A reduced-saturated-fat statement alone will not settle that choice. |
| Flavour and serving size | Check salt or sugars for the exact flavour, alongside its serving size. Tesco Groceries lists 1.60g salt per 100g for Propercorn Salted Microwave Popcorn and 3.4g sugars per 30g bag for Propercorn Sweet & Salty. | I may eat a whole small bag or take a portion from a larger one, so the pack's serving description needs to match what I will eat. |
| Ingredients and warnings | Read the exact pack's ingredient and allergen statements. Check preparation instructions for microwave popcorn and watch for unpopped-kernel warnings. | Milk or soya ingredients could change which flavour I choose, and I want to follow the instructions for the format I buy. |
They measure different things. Tesco Groceries lists 21.4g total fat per 100g for Metcalfe's Salted Caramel, alongside its claim of at least 30% less saturated fat than average salted-caramel-style popcorn.
Read the claim's comparison basis, then check total fat, saturates and protein separately on the pack.
Even the protein-enriched Myprotein example lists 3.8g protein per 21g bag, according to its product specification.
If protein is the main reason for the snack, consider a separate protein-containing food that fits your requirements.
Per-100g values make products easier to compare, but they do not describe how much you will get from a smaller serving or an entire sharing bag.
Compare per-100g figures first, then use the nutrition information for the amount you expect to eat.
Ingredients differ by product, and Tesco Groceries warns that Propercorn Sweet & Salty may contain an occasional unpopped kernel.
Check the current label for allergens and warnings, especially when changing flavour or format.
These examples describe specific popcorn products, not every variety made by each brand.
Its Protein Popcorn is a ready-to-eat option for shoppers comparing protein per portion.
Its microwave and ready-to-eat products illustrate why format and flavour need separate label checks.
Its Salted Caramel popcorn carries a saturated-fat comparison that should not be confused with a total-fat or protein claim.
These lightly sea-salted Propercorn options offer a choice between six individual 10g bags and one 70g bag to portion yourself. Check each pack's nutrition information before deciding how it fits your protein and total-fat priorities.

Six individual 10g bags give you a defined pack size for each snack. Check the current label for protein and total fat per bag, as well as ingredients relevant to you; the name does not establish a reduced-fat claim.

The 70g bag suits shoppers who want to decide their own portion. Use the current pack label to work out the protein and total fat for the amount you plan to eat, and check its ingredient information if needed.
The portions compared here provide relatively small stated amounts of protein: Myprotein lists 3.8g per 21g bag, Tesco Groceries lists 2.1g per prepared 20g serving of Propercorn Salted Microwave Popcorn and 1.4g per quarter-pack of Metcalfe's Salted Caramel. If protein is the main reason for the snack, compare those amounts with a separate protein-containing food that suits your requirements.
No: the Metcalfe's Salted Caramel statement compares saturated fat with average salted-caramel-style popcorn. Tesco Groceries lists 21.4g total fat per 100g for that product, so check the total-fat figure separately.
Check the ingredient and allergen statements on the exact pack. Myprotein lists whey protein isolate and soya lecithin in its Protein Popcorn, while Tesco Groceries lists a possible milk warning for Propercorn Salted Microwave Popcorn.
Yes. Follow the preparation instructions for microwave popcorn and compare its prepared serving with the amount you intend to eat; for either format, read the exact product's ingredient information and any unpopped-kernel warning.
