Quick hot-meal stockers
For pasta bakes, tuna-topped jacket potatoes or fishcakes, look for a format that is straightforward to portion and combine with ingredients already in the cupboard.
Who is stocking up?
Label-comparing family cooks
If you use tuna regularly or buy multipacks, compare the drained quantity, salt per 100g and instructions for storing any unused tuna. Similar-looking tins need not provide the same recipe quantity.
Source-conscious tuna buyers
If an MSC ecolabel or pole-and-line claim influences your choice, check it on the exact product. A claim on one tin does not establish how every tuna product from that brand was sourced.
What matters when choosing?
Choose the packing format for the meal you plan to make, then check the quantity and label details of the particular tin.
Chunks in spring water
Consider when: You want chunks for a pasta bake, jacket filling or fishcakes and intend to season the finished dish yourself.
Bear in mind: Spring-water tins can have different salt values, so the packing liquid alone is not a salt comparison.
Chunks in brine
Consider when: Brine suits the seasoning of the meal you are making.
Bear in mind: Princes lists water and salt in its brine chunks; account for the tin alongside other seasoned ingredients.
Oil-packed tuna
Consider when: You specifically want oil in the ingredient profile, rather than choosing solely by the word tuna on the front of the pack.
Bear in mind: Check the exact format and nutrition panel; Princes’ sunflower-oil sandwich tuna is not the same product as its brine chunks.
No-drain tuna
Consider when: Skipping the draining step makes a quick meal easier to prepare.
Bear in mind: Check the pack size and the basis of its nutrition figures before comparing it with standard drained chunks.

What is easy to overlook?
-
Assuming spring-water tuna has the same salt level across brands
Sainsbury’s lists 0.12g salt per 100g drained for its referenced spring-water product, while the referenced Tesco and Asda products each list 0.90g. Cheese, sauce or stock can also contribute salt to a pasta bake.
Compare salt per 100g drained on the exact tin, particularly when the rest of the dish is already seasoned.
-
Using tin weight as the recipe quantity
Liquid contributes to the labelled tin weight. Tesco’s referenced 145g tin has a drained weight of 102g, while its referenced four-pack lists 139g drained per tin.
Check drained weight against the amount of tuna your bake or jacket filling needs.
-
Comparing different tuna formats as though their labels were interchangeable
Princes lists 99kcal and 0.5g fat per 100g drained for its brine chunks, compared with 224kcal and 16.0g fat per 100g drained for its sunflower-oil sandwich tuna. Both the packing medium and the product format differ.
Choose the format for the recipe, then compare nutrition figures on the same stated basis.
-
Assuming every opened tin has the same storage window
The referenced Sainsbury’s product says to use refrigerated leftovers within one day; the referenced Tesco, Asda and M&S products specify two days. Their instructions also call for transferring unused tuna from the tin.
Before making a partial-tin recipe, check the product’s storage instructions and follow its stated timeframe.

Common questions
Does tinned tuna count as oily fish?
No. The NHS says fresh and canned tuna do not count as oily fish, so a tin of tuna does not fulfil its oily-fish recommendation.
How should I store tuna left after making a partial-tin meal?
Follow the instruction on the exact pack. The referenced Sainsbury’s, Tesco, Asda and M&S products call for transferring leftovers to a non-metallic container and refrigerating them; Sainsbury’s specifies use within one day, while the other referenced products specify two days.
What does NHS guidance say about tuna during pregnancy?
The NHS advises people who are pregnant or trying for a baby to have no more than four cans of tuna or two tuna steaks a week because tuna can contain higher levels of mercury. Count tuna eaten across meals, not just the tins kept for winter dinners.
What if someone eating the meal has a fish allergy?
Tuna contains fish and is not suitable for someone with a fish allergy. Check the exact pack’s ingredient and allergen information, and check any other ingredients added to the meal for their own allergens.
