For a secondary school lunchbox, choose according to what matters most to you: Connétable lemon fillets carry the claim “30% less salt”, while a jar of mackerel in olive oil listed by Carrefour carries the claim “no added salt”. These claims are not interchangeable. Also compare the “salt” value per 100 g, then check the pack size, ingredients and fish allergen information for the product you buy. A “plain” recipe does not guarantee a lower salt content.
You want to look for a specific claim, such as “30% less salt”, rather than relying on the word “plain” alone. You’ll still need to compare the “salt” value per 100 g to assess different tins.
You’re looking for a recipe labelled “no added salt”. Check its salt value too: this claim does not mean the product contains no sodium at all.
Fillets can be added to a sandwich or salad. The flavour of the recipe and how much your child will eat matter too, especially if they won’t finish the pack once it’s open.
Worth considering: if you’re looking for a stated reduction compared with a reference product, and a lemon marinade suits the meal.
Bear in mind: a comparative reduction does not necessarily mean this tin has the lowest salt content.
Worth considering: if your priority is a recipe with no added salt.
Bear in mind: sodium may be naturally present, and this claim alone does not rank the product against other canned options.
Worth considering: if you prefer a simple recipe to add to a sandwich or salad, without needing a salt-related claim.
Bear in mind: “plain” does not rule out added salt: Auchan plain fillets list salt among their ingredients.
| What to look for | What to check | Who is it for? |
|---|---|---|
| Stated salt reduction | Look for the exact claim, then compare the “salt” value per 100 g on an equivalent nutritional basis. | When choosing a tin for lunch, I want a clearly stated reduction without assuming it has the lowest salt content. Around 50% of consumers prioritise this stated reduction. |
| No added salt | Check the “no added salt” claim, the ingredients list and the “salt” value per 100 g. | If I’m preparing a meal without adding salt, the wording of the recipe is the first thing I look at. This lack of added salt would be the top priority for around 30% of consumers. |
| Portion size and leftovers | Choose an amount that suits the meal and read the storage instructions for after opening. | I’d rather finish the pack at lunchtime or be able to store any leftovers properly. Portion management would come first for around 20% of consumers. |
Auchan plain fillets contain salt in their ingredients list. So a simple-tasting recipe will not necessarily meet your needs if you’re looking for a lower salt content.
Compare the “salt” value per 100 g on your chosen tin with those of other products you’re considering.
The first claim is about whether salt has been added to the recipe; the second states a reduction compared with a reference product. Neither claim on its own tells you how the products compare in total salt content.
Decide which distinction matters to you, then check the “salt” line on each pack.
For Auchan plain fillets and Petit Navire P’tits filets, the instructions say to refrigerate after opening and consume within two days.
Choose a pack size that suits the amount planned for lunch, or plan how to use the leftovers according to the instructions on the product you buy.
Mackerel is a fish. This matters too if your child might share their lunchbox with another pupil.
Check the allergen declaration on the product you choose, and don’t share the meal with anyone who is allergic to fish.
Auchan lists the “Lemon-marinated mackerel fillets, no oil, 30% less salt” product in a 130 g pack.
Auchan’s product listing offers P’tits filets mackerel fillets in olive oil in a 90 g pack.
Auchan’s mackerel range lists several Saupiquet recipes, including plain, mustard, white wine, tomato and escabeche.
The range includes plain mackerel fillets in a 120 g pack.
No. On Connétable lemon fillets, this claim indicates a comparative reduction, not that the product is salt-free. To compare this tin with another, also check the “salt” value per 100 g on both packs.
No. On the jar of mackerel in olive oil listed by Carrefour, the claim means no salt has been added to the recipe; it doesn’t mean the product contains no sodium. Check the nutritional information for the exact product.
Mackerel belongs to the fish allergen category, which you should take into account before serving or sharing the meal. Check the allergen declaration on the pack you buy; the presence of crustaceans cannot be inferred just because the product contains mackerel.
Follow the instructions on the tin you buy and refrigerate any portion that needs to be kept chilled. Auchan’s product listings for Auchan plain fillets and Petit Navire P’tits filets say to consume within two days of opening, so choose a pack size that makes it easy to manage any leftovers.
