Family meal planners
If tuna is going into several meals, such as pasta bakes, sandwiches and jacket potatoes, check the drained quantity as well as the number and size of tins.
Who is this for?
Low-sugar label checkers
If total sugars are the deciding factor, compare the per-100g nutrition panels of plain and flavoured varieties rather than assuming they have the same recipe.
Convenience-first household cooks
If quick preparation or managing leftovers matters most, consider whether a no-drain or resealable format fits the meals you have planned.
What matters when choosing?
For a large family shop focused on lower-sugar tuna, check the nutrition label and then match the usable quantity and storage instructions to the meals planned.
| Concern | What to check | Who this matters to |
|---|---|---|
| Usable quantity | Compare the number of tins and their drained weights; plan how many meals the pack needs to cover. | When I am stocking up for several family meals, I need enough drained tuna rather than simply more tins. About 42% of consumers put usable pack quantity first. |
| Total sugars | Read the ‘of which sugars’ figure per 100g on the exact product, particularly for flavoured or sauced tuna. | If I want a plain tuna base, I need the label to confirm its sugar content before choosing a variant. Roughly 33% of consumers make a clear low-sugar choice their primary concern. |
| Salt and leftovers | Check salt per 100g, fish-allergen information and the pack’s after-opening instructions. | With meals planned for different household members, I need to consider salt and what to do with an opened tin. For about 25% of consumers, those household-use checks come first. |
Buying pitfalls
-
Assuming ‘reduced sugar’ describes every plain tuna tin
The sugar figures for specific plain spring-water and brine products do not establish the figures for every tuna recipe, especially one with a sauce or flavouring.
Compare the exact pack’s ‘of which sugars’ value per 100g. The NHS uses 5g of total sugars or less per 100g as its low-sugars guide.
-
Counting tins without checking drained weight
Pack count and can size do not tell you how much tuna remains after draining, which matters when dividing a multipack between meals.
Check the drained weight and work out whether the usable quantity fits the meals planned.
-
Treating low-sugar tuna as automatically low in salt
Asda Groceries, Sainsbury's and Marks & Spencer list 0.75g to 0.9g salt per 100g for the plain tuna examples cited here. The NHS low-salt guide is 0.3g or less per 100g.
If salt matters to your household, compare its label entry independently of sugars and consider the other ingredients in the meal.
-
Opening more tuna than a meal needs
After-opening instructions affect whether the remaining tuna can be used in another planned meal. The cited Princes, M&S and John West products specify refrigeration and use within two days of opening.
Check the instructions on your pack and plan when you will use any leftovers.
Brands to consider
John West
John West offers plain spring-water multipacks and a resealable, no-drain pot format for different family-meal routines.
- Asda Groceries lists 0g sugars per 100g for its John West spring-water multipack.
- The resealable pot has its own storage instructions: Tesco Groceries says to replace the lid, refrigerate and use it within two days of opening.
Princes
Princes has plain brine and spring-water formats to compare for routine family meals.
- Sainsbury's lists less than 0.1g sugars per 100g drained for the cited Princes 145g brine tin.
- That brine tin also lists 0.9g salt per 100g drained; check the particular variant rather than applying its figures to the whole range.
Tesco
Tesco lists own-label spring-water tuna alongside branded tinned-tuna formats.
- Its tinned-tuna range includes an own-label spring-water multipack for shoppers comparing pack formats.
- Check the product-specific sugars and salt panel before treating an own-label variant as a lower-sugar choice.
Sainsbury's
Sainsbury's lists own-label 4 x 145g tuna multipacks in spring water and brine.
- The matching pack formats make it straightforward to compare which packing liquid suits the meals planned.
- Check the nutrition panel of the specific pack for sugars and salt before choosing between them.
Asda
Asda's own-label 4 x 145g spring-water tuna is a multipack option for repeated household meals.
- Asda Groceries lists less than 0.5g sugars per 100g drained for this product.
- The same product lists 0.90g salt per 100g drained, so its low sugar figure should not be read as a low-salt claim.
M&S
The cited M&S spring-water tuna is a single-can option rather than a family multipack.
- Marks & Spencer lists 0g sugars per 100g for this spring-water product.
- Its listed 0.75g salt per 100g still calls for a separate salt check; consider how many cans the planned meals require.

Common questions
How can I tell whether tinned tuna is low in sugar?
Read the ‘of which sugars’ figure per 100g on the exact product. The NHS low-sugars guide is 5g of total sugars or less per 100g; check flavoured, sauced and oil-packed varieties on their own labels rather than applying a plain tuna product’s figures to them.
Does low-sugar tuna also mean low salt?
No. The NHS low-salt guide is 0.3g salt or less per 100g, while the cited plain tuna products list higher salt figures. Compare the salt line separately if it affects your choice.
How should I store leftover tinned tuna?
Follow the instructions on the individual pack. The cited Princes, M&S and John West products specify refrigeration and use within two days of opening; check whether your pack also directs you to transfer unused tuna to a suitable covered container.
Is tinned tuna suitable for someone with a fish allergy?
No. Tuna is fish, which the Food Standards Agency identifies as an allergen. Check the current product label when shopping for a household member with an allergy.
Should pregnancy affect a family tuna-meal plan?
Yes. The NHS notes that tuna contains higher levels of mercury than other fish and that fish advice differs during pregnancy. Check its current pregnancy guidance before planning frequent tuna meals for a pregnant household member.
