For a portable popcorn snack chosen primarily for its protein content, Myprotein Sweet and Salty Protein Popcorn declares 18g protein per 100g, compared with 6.0–8.1g per 100g across the ordinary sweet-and-salty products listed by Tesco Groceries and Sainsbury’s here. Its 21g bag still provides 3.8g protein and contains milk and soya ingredients. If vegan suitability or a different portion format matters more, compare the exact pack’s ingredients and nutrition panel rather than choosing by a protein-focused name alone.
If you want popcorn for a day trip, the amount in the bag you will actually eat matters alongside the per-100g figure. Myprotein declares 3.8g protein in its 21g Sweet and Salty bag; the smaller PROPER 14g pack listed by Tesco Groceries declares 1.1g.
PROPER Sweet & Salty is listed as suitable for vegans by Tesco Groceries and Sainsbury’s. Check the declaration on the exact pack you buy: a protein-focused popcorn is not necessarily vegan, and Myprotein’s Sweet and Salty variant contains whey protein isolate from milk.
Individual packs can be handed out separately, while a sharing bag can be divided using its stated serving size. Check safety wording before packing for children: Tesco Groceries lists Metcalfe’s Sweet ’N Salt as unsuitable for children under four because it may contain unpopped kernels.
Start with protein per 100g to compare packs of different sizes, then look at the amount in the portion you intend to take. Ingredients, other nutrition values and pack format can change which option works for your trip.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per portion | Compare declared protein per 100g, then per bag or stated serving. Myprotein lists 18g per 100g and 3.8g per 21g bag; Tesco Groceries lists 8.1g per 100g for Metcalfe’s Sweet ’N Salt. | I want to know how much protein is in the bag I will pack, not just how the figures compare on a per-100g label. |
| Ingredients and allergens | Read the exact flavour’s ingredients and allergen declaration. Myprotein Sweet and Salty contains whey protein isolate from milk and soya lecithin; Tesco Groceries lists its PROPER 14g pack as suitable for vegans. | If I am packing for someone who avoids particular ingredients, I need to check their pack rather than assume all popcorn has the same ingredients. |
| Pack size | Check the weight of each individual bag or the stated portions in a sharing bag. Tesco Groceries gives a 20g quarter-pack serving for Metcalfe’s 80g bag and a 27g quarter-bag serving for Tesco’s 110g bag. | For a day out, I might take one small bag; for a group, I might divide a sharing bag before leaving. |
| Other nutrition values | Compare sugars, fat and salt for the same flavour and serving basis. Tesco Groceries declares 22.6g sugars, 26.2g fat and 1.19g salt per 100g for Tesco Sweet & Salted Popcorn. | Protein is one part of my choice; I also want the rest of the nutrition panel for the portion I plan to eat. |
| Child safety | Read the exact pack’s kernel warning. Tesco Groceries lists Metcalfe’s Sweet ’N Salt as unsuitable for children under four because unpopped kernels may be present; its PROPER listing also warns of occasional unpopped kernels. | When packing for a family trip, I need a snack that matches the children’s ages and the product’s own safety instructions. |
Myprotein declares 18g protein per 100g for its Sweet and Salty variant, but its smaller 21g bag provides 3.8g. The two figures answer different questions.
Use the per-100g figure to compare products and the per-bag figure to judge the snack you will pack. Do not treat a small popcorn bag as a substitute for a meal.
Myprotein Sweet and Salty Protein Popcorn contains milk-derived whey protein isolate and soya lecithin, so its protein figure does not make it suitable for every diet.
Check the ingredients and allergen declaration on the exact flavour and pack before buying for someone with an allergy or dietary restriction.
Tesco Groceries gives quarter-bag servings for the Metcalfe’s 80g and Tesco 110g products. Their per-serving figures do not describe the whole bag.

Tesco Groceries states that Metcalfe’s Sweet ’N Salt is not suitable for children under four because it may contain unpopped kernels. Its PROPER listing also warns that occasional unpopped kernels may be present.
