For pie and mash, check the sugars declaration on the exact tin rather than treating “reduced sugar” as a distinct type of tuna: the cited plain spring-water and brine products declare 0.0g sugars per 100g drained. Then choose a packing medium and portion format that suit the meal, comparing salt on a drained basis and checking fat and energy if considering tuna in oil.
If “reduced sugar” brought you to the tuna shelf, compare the declared sugars on the exact pack rather than assuming the phrase distinguishes one plain tin from another. Cited products from Princes, John West and M&S declare 0.0g sugars per 100g drained.
If the tuna will go into a filling or over mash, decide whether you want identifiable chunks and how much drained fish the recipe needs. Check the fat and energy declarations when comparing spring-water tuna with an oil-packed option.
If the rest of the plate is already seasoned, compare salt per 100g drained before choosing between spring water and brine. The cited M&S spring-water, John West spring-water, Princes spring-water and Princes brine products list different salt values, so the packing-medium name alone is not enough.
For pie and mash, start with the exact tin’s nutrition panel, then check whether its packing medium, pieces and drained quantity fit your recipe.
| Concern | What to check | Who this matters to |
|---|---|---|
| Sugars declaration | Read sugars per 100g drained and the ingredients on the exact variant, particularly if it has a sauce or flavouring. | If I am choosing tuna because of “reduced sugar”, I want to see the actual declared value rather than rely on a comparative-sounding phrase. About 36% of consumers put that sugar-label check first. |
| Salt and packing medium | Compare salt per 100g drained; check fat and energy separately if choosing an oil-packed tin. | When pie, gravy or mash is already seasoned, I want to know what the tuna adds to the plate. For about 29% of consumers, balancing salt and packing medium is the primary need. |
| Pieces and drained portion | Check whether the tin contains chunks or steak and read its drained weight before planning the filling or topping. | I may want pieces that remain distinct in a topping, or tuna that mixes through a filling, with enough drained fish for the recipe. About 21% of consumers chiefly need to settle the format and portion. |
| Pack format | Check the number of cans and the quantity stated for each can or bundle. | If I am buying for one meal or several, I need a pack size I can use and store. That is the main concern for about 14% of consumers. |
A comparative nutrition claim and the sugars declaration for one product answer different questions. The cited plain spring-water and brine tins already declare 0.0g sugars per 100g drained; that does not establish a reduced-sugar comparison between them.
Read the current nutrition panel and ingredients of the tin you intend to use, especially if it contains a sauce or flavouring.
A sugars value does not tell you how much fat or energy an oil-packed product contributes to a pie filling or mash topping.
Compare the oil-packed tin’s fat and energy declarations with those of the spring-water tin you are considering, on the same drained basis.
The cited M&S spring-water tin lists 0.75g salt per 100g, while the cited Princes spring-water and brine tins list 0.85g and 0.90g respectively per 100g drained. Gravy, cheese or seasoned mash can also affect the meal’s overall salt content.
Compare the exact tins’ salt declarations and consider the other ingredients before deciding which packing medium suits the dish.
The cited spring-water multipack is an option for cooks comparing a stated 0g sugars and 25g protein per 100g drained.
Its cited spring-water and brine chunks let you compare packing media while checking the sugars line on each product.
Tesco’s spring-water tuna range offers formats to consider when planning how much fish a recipe needs.
An own-label option to compare with branded tuna when shopping for a pie filling or topping.
An own-label option to assess against the same meal requirements as other tins.
The cited spring-water chunks provide another labelled plain-tuna option for the meal.
These spring-water and brine tuna chunks offer pack formats to consider for a pie filling or a topping alongside mash. Compare each tin’s declared sugars and drained quantity with the amount your recipe calls for.

No. A sugars declaration describes the stated amount in that product; “reduced sugar” is a comparative nutrition claim, and UK nutrition claims are regulated, as Department of Health and Social Care guidance explains. Check the exact tin’s current sugars declaration and ingredients rather than assuming its comparison with another product.
Choose by the tuna’s role in the dish, then compare the exact labels. Spring-water and brine products can both declare 0.0g sugars, while their salt figures differ: the cited Princes spring-water tin lists 0.85g salt and its brine tin 0.90g per 100g drained. If considering oil-packed tuna, compare its fat and energy declarations as well as sugars.
No. The NHS states that fresh and canned tuna do not count as oily fish, regardless of the packing medium in the tin.
Follow the directions on the exact pack. The listed John West and Morrisons products direct you to move unused tuna to a non-metallic container, refrigerate it and use it within 2 days of opening; check the container and storage directions for the product you buy.
Tuna is fish, so these tuna products are not suitable for someone with a fish allergy. Check the exact tin’s allergen statement and the labels of the other pie ingredients before preparing or serving the meal.
