Regular pantry stocker
You use tuna across several meals and want a pack quantity you can store and use before its best-before dates. Check the number and size of the individual tins as well as the total bundle.
Who is this for?
Salt-conscious tuna buyer
You want to compare spring-water and brine products using the salt figure on each exact nutrition label, rather than treating the packing medium as a guarantee.
One-person meal planner
You usually need tuna for a small meal. Individual tin size and whether the product needs draining may matter more to you than the largest possible cupboard stock.
What matters when choosing?
For a retirement-oriented household or shop, start with how often the tuna will be used. Then compare tin size, packing medium and the information on the exact pack.
| Concern | What to check | Who this matters to |
|---|---|---|
| Cupboard stock | Check the number of tins, individual tin size and best-before dates against your expected use. | When stocking tuna for regular meals, I need enough unopened tins without taking home more than I can use. About 33% of consumers put planned cupboard stock first. |
| Salt and packing medium | Compare salt per 100g on the exact labels, noting whether the figures use the same drained-weight basis. | If salt matters to me, I want to assess the actual can rather than judge it by brine or spring water alone. About 27% of consumers prioritise salt and packing medium. |
| Portions and leftovers | Check individual tin size, whether the format is no-drain and the post-opening storage instructions. | For a one-person lunch, I would rather open a suitable tin than manage unused tuna. Roughly 20% of consumers put portion size and preparation first. |
| Labelling and handling | Read the fish allergen declaration and check any sourcing or opening claims on the exact pack. | When shopping for others, I need clear fish identification and any sourcing information that matters to them. About 20% of consumers primarily consider labelling and handling. |
Buying pitfalls
-
Judging quantity by tin count alone
Four tins of one size and four tins of another provide different amounts for meal planning. A larger bundle also needs enough cupboard space and a realistic plan for using it.
Compare individual tin sizes, the stated bundle contents and best-before dates before stocking up.
-
Assuming spring water determines the salt level
Salt values vary by product. Princes lists 0.85g salt per 100g drained for its researched spring-water chunks, while John West lists 0.9g per 100g for its researched brine four-pack; those figures describe different products, not every tin in either medium.
Read the salt line on the exact pack and compare figures stated on the same basis.
-
Opening a large tin without a leftover plan
An individual tin can leave unused tuna if the meal needs only a small amount. M&S instructs buyers of its researched spring-water product to transfer unused contents to a non-metallic container, refrigerate them and eat them within two days.
For smaller meals, compare individual tin sizes and follow the post-opening instructions on the tin you buy.
-
Counting tuna as oily fish
The NHS says fresh and canned tuna do not count as oily fish.
If you are choosing fish specifically for an oily-fish portion, do not count tinned tuna as that portion.
Brands to consider
These brands provide useful product formats or label details to compare; a brand name alone does not establish the contents of every pack.
Princes
Princes lists spring-water tuna chunks in single 145g tins and several multipack sizes, including 4 x 145g, 6 x 145g and 8 x 145g.
- Its researched spring-water product lists tuna and spring water as ingredients.
- Check the packing medium and nutrition label of the particular Princes pack you select; the spring-water details do not describe its brine or oil products.
John West
John West provides a brine-chunk four-pack for comparison with its separately listed no-drain formats.
- The brand lists tuna, water and salt for its researched brine four-pack, with 0.9g salt per 100g.
- A ring pull or no-drain description should be checked on the exact format; it does not establish how easy that tin will be for a particular person to use.
Tesco
Tesco listed own-brand tuna chunks in brine and spring water in 3 x 80g packs, offering a smaller-tin format to compare with larger multipacks.
- The stated individual tin size is useful when planning small meals.
- Check the current product label for the packing medium and drained quantity rather than applying one own-brand listing to the whole range.
M&S
The researched M&S spring-water tuna is a 160g product with product-level sourcing and post-opening storage information.
- M&S describes this product as skipjack tuna and says it is traceable and pole-and-line caught under its Forever Fish policy.
- Those sourcing statements are M&S claims about the researched product, not an independent assessment of every M&S tuna format.

Image unavailablePrinces Tuna Chunks in Brine 4 x 145g x 12 Packs
The stated bundle suits someone planning to use tuna regularly across meals. Its title specifies twelve packs of four 145g tins; check that quantity and the best-before dates before committing cupboard space.
Image unavailablePrinces Tuna Chunks in Brine 4 x 145g
This four-tin pack offers a smaller stock-up than the stated twelve-pack bundle. Each tin is labelled 145g; compare the exact can’s salt information if brine is a consideration.
Image unavailableJohn West Tuna Chunks in Springwater 4 x 125g
Four 125g tins offer a spring-water option for planned cupboard use. If avoiding draining is important, confirm whether this exact pack is labelled no-drain rather than relying on descriptions of other John West formats.
Image unavailablePrinces Tuna Chunks in Sunflower Oil 4 x 145g
This four-tin format is for shoppers who want tuna packed in sunflower oil. Each tin is labelled 145g; check the basis of any nutrition figures before comparing them with drained-weight figures for other packs.
Image unavailableMorrisons Fad Free Tuna Chunks in Spring Water 145g (6 Packs)
The title states six packs of 145g spring-water tuna for a larger pantry purchase. Confirm the exact pack count and total quantity on the listing before ordering, as the pack-level quantity information is not consistent.
Common questions
Is tinned tuna suitable for someone with a fish allergy?
No. Tuna is fish, which the Food Standards Agency identifies as an allergen that can pose a risk to someone with a fish allergy. Check the current ingredients and allergen declaration on the exact tin when shopping for another person.
What should I do with tuna left in an opened tin?
Follow that product’s storage instructions. M&S says unused contents of its researched spring-water tuna should be moved to a non-metallic container, refrigerated and eaten within two days; do not assume every brand gives the same instructions.
Does canned tuna count as oily fish?
No. The NHS states that fresh and canned tuna do not count as oily fish. If an oily-fish portion is the reason for the purchase, choose a fish that meets that description instead.
Should I automatically choose spring-water tuna to limit salt?
No. Compare the salt figure on the exact products you are considering, using the same per-100g basis where possible. The packing medium alone does not tell you the salt level of a particular tin.
