For plain tinned tuna, a reduced-sugar claim is less useful than the actual label: the Princes, Tesco and M&S examples reviewed declare 0g sugars or less than 0.1g per 100g. Choose spring water when you want a plain base for the dish, or brine when its seasoning suits the recipe; then compare salt per 100g, ingredients, drained weight and fish allergen information on the exact tin.
If you searched for reduced-sugar tuna, start with the declared sugars per 100g. The plain Princes, Tesco and M&S products reviewed declare 0g or less than 0.1g; that figure alone does not establish a reduction compared with another tin.
For a salad, pasta dish, jacket-potato topping or sandwich filling, consider the packing medium, the cut of tuna and how much drained tuna the pack provides.
A negligible sugars declaration does not settle the salt question. Compare salt per 100g on the exact tins you are considering, rather than assuming spring water or brine tells you the amount.
For plain tuna at Easter lunch, check the sugars declaration, then choose a format that works in the dish and compare the remaining label details.
| Concern | What to check | Who this matters to |
|---|---|---|
| Sugars declaration | Compare sugars per 100g and the ingredients on the exact tin. Check flavoured or sauce-based products separately from plain tuna. | If I am shopping for reduced-sugar tuna, I want to know what the tin actually declares, not assume that 0g proves a reduction. About 46% of consumers put sugar-label clarity first. |
| Dish and format | Choose the packing medium and cut for the planned dish; use drained weight to judge how much tuna the pack provides. | For a lunch salad, topping or filling, I need tuna that works in the dish and enough drained fish to serve it. Meal format is the primary concern for about 27% of consumers. |
| Salt and serving checks | Compare salt per 100g, check the fish allergen declaration and follow the pack's instructions for leftovers. | Even when the sugars figure suits me, I need to account for salt, fish allergy needs or tuna left after lunch. About 27% of consumers prioritise those checks. |
The plain Princes, Tesco and M&S examples reviewed already declare 0g sugars or less than 0.1g per 100g. A tin's sugars figure does not, by itself, show that its recipe has less sugar than another product.
Compare the per-100g declaration and ingredients on each tin, particularly when considering a flavoured or sauce-based option.
In the Tesco examples reviewed, both spring-water and brine tuna declare 0g sugars, but their listed salt figures are 0.90g and 1.00g per 100g respectively.
Compare salt using the same per-100g basis on the current labels; do not use the packing medium as a substitute for the figure.
Packing liquid is not drained tuna, so the outer weight can mislead when you are deciding how much fish a lunch dish will contain.
Check the drained weight, especially when comparing single tins with multipacks.
The reviewed tuna products identify fish as an allergen. Tesco's reviewed products also instruct shoppers to transfer unused contents to a covered, non-metallic container, refrigerate and consume them within two days.
Check allergy needs before serving, and follow the storage directions on the tin you open.
Its plain spring-water tuna is a reference point for comparing sugars and salt on a specific product, rather than across the whole Princes range.
The reviewed own-brand spring-water and brine products allow a product-specific comparison of packing medium and label values.
M&S describes its 160g spring-water chunks as an option for dishes such as pasta bakes and jacket-potato toppings.
Tesco lists John West No Drain tuna formats in its tinned-tuna range.

Consider brine if its seasoning suits your salad, sandwich filling or pasta dish.
Four 145g tins; compare salt per 100g on the current label rather than assuming its value from the brine format.

The No Drain format may appeal when you want to add chunks directly to a salad or sandwich filling.
Three 100g tins; confirm the packing medium on the current pack and check the basis of its per-100g nutrition figures before comparing them with drained-weight labels.
Compare its declared sugars rather than relying on that phrase. The plain Princes, Tesco and M&S examples reviewed declare 0g or less than 0.1g sugars per 100g, but a 0g declaration does not prove a reduction against another product.
Choose spring water for a plain base, or brine if its seasoning suits your dish. In the reviewed Tesco products, both declare 0g sugars, while the listed salt figures are 0.90g per 100g for spring water and 1.00g for brine; check the labels of the tins you intend to buy.
Compare sugars and salt per 100g on the exact products, then check ingredients, fish allergen information and drained weight. NHS food-label guidance explains the per-100g nutrition basis, which makes it useful for comparing packs of different sizes.
Use the drained weight rather than the weight of tuna and packing liquid together. That matters when choosing between single tins and multipacks for a salad, topping or filling.
Follow the opened-pack directions on your tin. Tesco instructs shoppers to transfer unused contents from its reviewed products to a covered, non-metallic container, refrigerate them and consume them within two days.
