Busy lunchbox planners
For lunches prepared in a hurry, a no-drain format removes a preparation step. A smaller can may also mean less opened tuna to store when the intended portion is small.
Who is this for?
Flexible family-meal stockers
When tuna is going into sandwiches, jacket potatoes, pasta or salads across the week, can size, packing medium and the texture of chunks or steaks may matter more than single-portion convenience.
Allergen- and label-checking households
Tuna contains fish, which the Food Standards Agency identifies as an allergen. Check the purchased product’s ingredients, allergen information and after-opening instructions, particularly when choosing between variants.
What matters when choosing tinned tuna?
Start with the portion and preparation you need, then check the exact can’s label before putting it in the cupboard.
| Concern | What to check | Who this matters to |
|---|---|---|
| Quick, low-mess preparation | Look for an explicit no-drain label and a can size that fits the intended lunch. | When lunch must be assembled quickly or away from a sink, avoiding a draining step is the priority. About 36% of consumers put preparation convenience first. |
| Meals across the week | Match the can size and chunk or steak format to the recipes you plan to make. | If the same cupboard ingredient needs to work in sandwiches and family meals, flexibility matters more than a single-serving pack. Around 29% of consumers make versatile meal use their primary concern. |
| Allergens and label details | Check the full ingredients, fish-allergen information and after-opening directions on the purchased can. | When preparing food for others, I need to identify allergens and know how to handle any leftovers. For about 21% of consumers, those label and storage checks come first. |
| Fishing method and traceability | Check whether a sourcing or certification claim applies to the exact product, rather than the brand generally. | If a stated catching method or traceability feature guides my choice, I want to see it on the can I am buying. Roughly 14% of consumers prioritise those sourcing details. |
Common buying mistakes
-
Treating every tin of tuna as interchangeable
Spring-water chunks, oil-packed steaks and other variants can differ in ingredients, nutrition and texture. Marks & Spencer lists different fat values per 100 g for its spring-water chunks and sunflower-oil steak; that comparison applies to those two products.
Choose for the intended recipe and compare the exact products’ ingredients and nutrition panels.
-
Opening more tuna than the meal needs
A large can used for a small lunch leaves tuna to store. The after-opening period varies: the cited Asda small-can product says to use refrigerated leftovers within two days, while the cited M&S oil-packed steak specifies 24 hours.
Match the can to the portion. Transfer unused contents to a suitable non-metallic container, refrigerate them and follow that pack’s instructions.
-
Confusing fish and shellfish allergen checks
Tuna contains fish and is unsuitable for someone with a fish allergy. The word ‘tuna’ alone does not establish whether a particular product has any shellfish-related ingredient or warning.
Read the full ingredients and allergen information on the exact can when managing an allergy.
-
Applying a sourcing claim to an entire brand
A catching-method or certification statement attached to one tuna product does not establish the same feature for every variant from that brand.
Check the wording on the product you intend to buy alongside its pack format and ingredients.
Brands and own-label ranges to consider
John West
A reference point for choosing between spring-water chunks and a no-drain format.
- Asda lists a John West No Drain tuna product described as ready to eat without draining.
- Check the exact variant: the no-drain description, pack size and any sourcing claim should not be assumed to apply to other John West cans.
Princes
A range to consider when the choice is between chunks, sandwich tuna, steaks and prepared tuna formats.
- Princes describes these formats in its tuna range and says its tuna is traceable to the original boat.
- The range description does not make the ingredients, nutrition or pack size interchangeable; check the selected product.
Asda
An own-label option for spring-water chunks in different can sizes.
- Asda lists spring-water tuna chunks in 4 × 145 g and 3 × 80 g packs, giving shoppers different portion sizes to consider.
- Use the chosen pack’s own nutrition and storage directions; a smaller can is useful only if its portion fits the meal.
M&S
Product lines to compare when both tuna texture and packing medium matter.
- Marks & Spencer lists spring-water chunks and sunflower-oil tuna steak. Their stated fat values are 0.6 g and 6.4 g per 100 g respectively.
- Those figures belong to two named products, not every water- or oil-packed tuna. Check each product’s label and any product-specific sourcing wording.

Questions about buying and storing tinned tuna
Is tinned tuna suitable for someone with a fish allergy?
No. Tuna contains fish, which the Food Standards Agency identifies as an allergen. Read the purchased product’s full ingredients and allergen information for any other relevant warnings; do not assume a shellfish warning from the word ‘tuna’ alone.
What should I do with tuna left after opening a can?
Follow that can’s storage instructions. The cited Asda small-can product directs shoppers to transfer unused contents to a suitable non-metallic container, refrigerate them and use them within two days; the cited M&S sunflower-oil steak specifies 24 hours. Check the period on the product you open.
Do spring-water and oil-packed tuna have the same nutrition?
Not necessarily. Marks & Spencer lists 0.6 g fat and 99 kcal per 100 g for its spring-water chunks, compared with 6.4 g fat and 159 kcal per 100 g for its sunflower-oil tuna steak. These are two specific products, so compare the panels on the exact cans you are choosing.
Should I buy small cans or a larger multipack for lunches?
Choose a can size close to the amount you expect to use at one time if storing leftovers would be inconvenient. A larger multipack may suit repeated meals, but its individual cans can still leave unused tuna after a small lunch; check the can sizes and after-opening instructions before deciding.
