Start with the exact tin’s nutrition panel rather than searching only for a reduced-sugar claim: ordinary tinned tuna can already list very little or no sugar. For a Boxing Day buffet, choose the packing liquid and format to suit the dish, then compare sugars, salt, fat and usable quantity on the relevant label basis.
If the buffet calls for a low-sugar ingredient, the useful comparison is the exact tin’s “of which sugars” figure, not whether its name includes a sugar claim. Sainsbury’s product listings show why the variant and label basis matter.
Sandwich fillings, salads and toppings call for enough usable tuna without opening more tins than needed. Pack format, drained quantity and the instructions for opened leftovers all affect the plan.
When a recipe has its own dressing, spring-water or brine-packed tuna may be the starting point. Oil-packed tuna offers a different base; check its ingredients and nutrition panel rather than treating the packing liquids as interchangeable.
Decide what the buffet dish needs, then compare labels on the same per-100g or drained-weight basis where possible. The groups below distinguish consumers by their main buying concern.
| Concern | What to check | Who this matters to |
|---|---|---|
| Actual sugar figure | Read “of which sugars” for the exact variant, noting whether the figure is per 100g, per serving or per 100g drained. | If keeping sugar down is my main concern, I need a figure I can compare rather than a search-filter label. About 31% of consumers put that label check first. |
| Usable quantity and preparation | Compare drained weight and pack format; plan how opened leftovers will be stored using the tin’s instructions. | When I am making several buffet dishes, I need enough tuna to use without unnecessary draining or leftovers. That is the primary concern for about 31% of consumers. |
| Recipe texture | Choose chunks or steaks for the intended dish, and check whether its dressing suits spring water, brine or oil. | If the filling has its own dressing, I may want a different tuna base from one intended for a simple topping. About 23% of consumers chiefly weigh up that recipe fit. |
| Guest and nutrition details | Check the exact salt and fat figures, keep fish-allergen information available and consult relevant NHS tuna guidance when planning for a pregnant guest. | For a shared buffet, I want guests to be able to identify the fish ingredient and assess the dish against their needs. For about 15% of consumers, those details take priority. |
These priorities lead to different checks, not a single winning packing liquid. For example, Sainsbury’s lists sugars below 0.5g per half can for its Tuna Steak in Sunflower Oil 3x120g, while its listing for Princes Tuna in Sunflower Oil 145g gives 0.0g per 100g drained. Those figures use different bases and apply to those named products only.
A plain tuna product can list very little or no sugar without using that phrase. Searching by the phrase alone may exclude a tin that otherwise suits the recipe.
Check “of which sugars” on the exact label, then compare salt, fat and ingredients on a consistent basis.
A multipack, a larger can and a no-drain pack do not necessarily provide the same amount for fillings or toppings.
Work from the quantity the recipe needs and check drained weight where applicable. Plan any leftovers around that product’s storage instructions.
Spring water, brine and sunflower oil give you different ingredients to work into a dish. Salt and fat figures also need checking on the chosen tin, rather than inferring them from the liquid’s name.
Choose the base to fit the dressing and compare the exact products’ nutrition panels before settling on one.
Tuna is fish, which matters when guests need to identify allergens. Instructions for opened leftovers can differ between tins.
Keep the ingredient information available beside the buffet and follow the chosen pack’s directions for transferring, refrigerating and using leftovers.
A reference point for comparing conventional tins with no-drain chunks. Tesco Groceries lists John West No Drain Tuna Chunks with a Little Spring Water MSC 3x100g.
Its listed tuna formats provide examples for comparing packing liquid, pack size and the exact variant’s label.
Tesco Groceries lists own-brand spring-water and brine formats, including a 400g spring-water can alongside multipacks.
Its Tuna Steak in Sunflower Oil 3x120g is a specific oil-packed example for checking both nutrition and storage instructions.
These tuna chunks cover no-drain packs and conventional multipacks in spring water, brine and sunflower oil. Choose the format for the buffet dish, then use the exact pack label for nutrition and usable-quantity comparisons.

A no-drain option to consider when assembling a buffet filling or topping quickly. The pack contains 3 x 100g of spring-water tuna chunks; check the usable quantity and nutrition panel for the exact pack when planning portions.

Consider this when a no-drain oil-packed base fits the filling. It contains tuna chunks in sunflower oil in a 3 x 100g pack; compare its sugar, fat and salt figures on the exact label, along with the usable quantity.

The four-tin format may suit several buffet dishes that call for oil-packed chunks. Allow for draining and check the pack’s drained quantity, nutrition panel and any serving instructions before preparing the dishes.

Consider spring-water chunks when the buffet recipe supplies its own dressing. This is a 4 x 125g pack; check the drained quantity for portion planning and do not assume it has a no-drain format.
No image available
A brine-packed option for a buffet recipe that does not call for oil. The pack contains four 145g tins of tuna chunks; allow for draining and compare the exact salt figure and drained quantity before deciding how many tins to open.
No particular phrase is needed to compare tins for a low-sugar buffet ingredient. Read the exact “of which sugars” line: Sainsbury’s lists below 0.5g per half can for its Tuna Steak in Sunflower Oil 3x120g and 0.0g per 100g drained for Princes Tuna in Sunflower Oil 145g. Compare the different label bases carefully.
Choose according to the dish rather than treating the packing liquid as a sugar shortcut. Spring water can suit a filling with its own dressing, brine offers another savoury base, and oil changes the ingredients and texture; check the chosen tin’s salt and fat figures before deciding.
Follow the instructions on the tin you open. Sainsbury’s says to transfer leftovers from its Tuna Steak in Sunflower Oil 3x120g to a non-metallic container, refrigerate and use within 1 day; its Princes Tuna in Sunflower Oil 145g listing says to use a sealed container in the fridge and consume within 2 days.
Make clear that it contains fish and keep the tin’s ingredient information available, including information for any other ingredients added to the dish. Guests can then identify what is in the finished filling, salad or topping rather than relying on its name alone.
