Shoppers checking sugars
If you are buying tuna for festive sandwiches, a buffet or leftovers, the exact tin matters more than a reduced-sugar search term. Plain tuna and tuna in a sauce or prepared recipe should be checked separately.
Who is this for?
Christmas meal planners
For several planned dishes, compare pack size with drained weight and think about which meals will use an opened tin. Spring water, brine and oil also give you different ingredients and nutrition panels to consider.
Households with additional food checks
If anyone eating the meal has a fish allergy, check the allergen declaration. If the food shop includes tuna for someone pregnant or trying for a baby, the Food Standards Agency’s reported intake guidance is a separate consideration from sugars.
What matters when choosing?
For plain tuna, confirm the sugar figure on the tin, then weigh the format against the dish and any household food checks.
| Concern | What to check | Who this matters to |
|---|---|---|
| Sugars in the exact tin | Read the ingredients and sugars per 100g drained. Check flavoured or sauce-based tuna separately from plain tins. | If I want plain tuna for sandwiches or a buffet, I need to know what this tin contains rather than rely on a reduced-sugar search term. About 50% of consumers put that label check first. |
| Packing liquid and meal size | Compare drained weight, salt, fat and energy on the same per-100g basis; match the pack size to planned servings. | A pasta bake and a sandwich filling may call for different tuna formats, and I need enough drained tuna for the dishes I have planned. Choosing the format and quantity is the primary concern for about 30% of consumers. |
| Allergens, storage and intake | Check the fish declaration and opening instructions. Where relevant, consider tuna eaten across the week as well as this purchase. | Before stocking up for several meals, I need to account for a fish allergy, opened-tin storage or pregnancy-related intake guidance in my household. Those checks come first for about 20% of consumers. |
Buying mistakes to avoid
-
Assuming a reduced-sugar claim settles the choice
Plain tins can already list very little sugar. The Princes brine, ASDA spring-water and Tesco spring-water products checked for this article list 0.0g or less than 0.5g sugars per 100g drained, but their other label details are not interchangeable.
Compare the current tin’s sugars, salt and ingredients, using the same per-100g drained basis where available. Choose the packing liquid for the dish rather than for a sugar claim alone.
-
Judging salt by the words “spring water” or “brine”
The packing liquid does not establish the salt figure. Checked plain spring-water and brine products list values from 0.75g to 0.90g salt per 100g drained.
Read the salt line on the two tins you are considering before choosing one for several Christmas dishes.
-
Planning the shop but not the opened tins
Multipacks can cover several meals, but an opened tin has different storage instructions from an unopened one. Checked retailer labels instruct shoppers to transfer leftovers to a non-metallic container, refrigerate them and use them within 2 days.
Choose tin sizes that fit the servings you have planned, and follow the instructions on the pack you buy.
Unused tuna may go to waste if it cannot be used within the pack’s stated period after opening.
-
Letting a low sugar figure obscure other food checks
Tuna is fish, so its sugar figure does not address a fish allergy. Pregnancy and trying-to-conceive intake guidance concerns tuna eaten across meals, not whether a tin is reduced in sugar.
Check the allergen declaration. Where the intake guidance applies, account for tuna across the week before buying tins for multiple meals.
Tinned-tuna brands for reference
Use named products and their current labels for comparisons; a figure for one tin does not describe every product from its brand.
John West
Its range includes spring-water chunks and no-drain formats for different preparation needs.
- An ASDA Groceries listing for a John West spring-water multipack gives 0.0g sugars per 100g drained.
- Check the exact pack: the listed nutrition and ingredients cannot be assumed for other John West formats.
Princes
Its tinned-tuna range includes brine and spring-water formats for plain tuna dishes.
- Princes Food & Drinks lists 0.0g sugars per 100g drained for its Tuna Chunks in Brine.
- That product also lists 0.9g salt per 100g drained; compare salt on the particular alternative tin if it matters for the meal.
Tesco
Tesco own-label spring-water and sunflower-oil tins allow a comparison between packing liquids within its range.
- Tesco Groceries lists less than 0.1g sugars per 100g drained for the checked spring-water and sunflower-oil products.
- Their fat and energy figures differ, so the oil-packed tin should not be treated as the same nutritional choice simply because its sugars are similar.
Asda
Asda own-label spring-water multipacks offer a plain-tuna option for meals using several tins.
- ASDA Groceries lists less than 0.5g sugars per 100g drained for its checked spring-water multipack.
- Read the pack you buy, as product information can change.
M&S
Its spring-water tuna chunks are another named product to compare by label rather than by packing-liquid description alone.
- Marks & Spencer lists 0.0g sugars and 0.75g salt per 100g for its Tuna Chunks in Spring Water.
- Those figures describe the named product, not every M&S tuna tin.

John West Tuna Chunks in Springwater 4 x 125g

Image unavailable
Princes Tuna Chunks in Brine 4 x 145g
This four-pack is a brine option for meals where plain tuna suits the recipe. Compare its salt figure with the particular spring-water tin you might otherwise buy; the packing liquid alone does not establish which has less salt.

John West No Drain Tuna Chunks in Springwater 3 x 100g
The no-drain format and three 100g tins may suit smaller planned portions with less draining during preparation. When comparing nutrition figures with conventional tins, check whether each label uses a drained-weight basis.
Image unavailable
John West Tuna Chunks in Sunflower Oil 4 x 125g
Choose an oil-packed tin when that format suits the planned dish, rather than assuming it offers a sugar advantage. This pack contains four 125g tins; compare its current fat, energy and salt figures with a spring-water alternative if those differences affect your choice.
Questions about buying and using tinned tuna
Do I need reduced-sugar tinned tuna for Christmas meals?
Check the exact label before seeking a reduced-sugar version. Plain spring-water and brine products checked by Princes Food & Drinks, ASDA Groceries and Tesco Groceries list 0.0g or less than 0.5g sugars per 100g drained; flavoured or sauce-based products need a separate check.
Is spring-water tuna always lower in sugars than brine or oil-packed tuna?
No such conclusion follows from the packing liquid alone. The checked plain spring-water, brine and sunflower-oil products all list very little sugar, while other nutrition figures vary. Compare the specific tins on the same label basis and choose a format that suits the dish.
How should I keep tuna left over from an opened tin?
Follow the tin’s opening instructions. Checked retailer labels say to move unused tuna to a non-metallic container, refrigerate it and use it within 2 days; plan servings around the instructions on the pack you buy.
What tuna intake guidance applies during pregnancy or when trying for a baby?
The Food Standards Agency reports NHS guidance of no more than four medium cans of tuna a week or two tuna steaks a week for people who are pregnant or trying for a baby. This concerns total tuna intake across meals, not the sugar figure on a particular tin.
Which date should I check when buying tins ahead of Christmas?
Check the can’s best-before date and storage instructions against when you plan to use it. GOV.UK explains that a best-before date concerns quality; after opening, follow the product’s separate storage instructions.
