Lower-salt tinned tuna for barbecue meals: what to check

Who this is for

Salt-conscious barbecue cooks

If tuna is going into a barbecue salad, grilled wrap or toastie, you want to compare its declared salt content before adding other ingredients. The NHS advises checking salt in packaged foods and sauces.

Fast outdoor-meal preparers

You want tuna that is straightforward to portion for a quick barbecue accompaniment. John West and Princes describe specific no-drain or drained products as ready to use, though their salt values still need checking.

Family cooks planning portions

For shared grilled sandwiches or salads, you need to know how much usable tuna a tin or multipack provides as well as its salt per 100g. Tesco, for example, lists a drained weight separately from the tin size for its 3x80g pack.

What to check when buying

For barbecue meals, start with the salt declaration on the exact tuna product, then consider preparation and the quantity you can serve.

Concern	What to check	Who this matters to
Salt in the tuna	Compare salt per 100g on the same stated basis, then check the portion you will use. Spring water alone does not establish the salt level.	For a wrap or salad with other seasoned ingredients, I want to know what the tuna contributes before choosing the tin. Keeping that contribution down would be the primary need for about 45% of consumers.
Quick preparation	Check whether the exact product is no-drain or already drained, and read its salt declaration.	When assembling food beside the grill, I may prefer tuna that needs little liquid handling. About 33% of consumers would put that preparation need first.
Enough usable tuna	Compare the drained weight where stated and the number of tins needed for your dish.	If I am making several grilled wraps or a shared salad, the amount left after draining matters to my portions. That would be the leading concern for about 22% of consumers.

Common buying mistakes

Assuming spring water means lower salt

Sainsbury's lists 0.12g salt per 100g drained for its 4x145g tuna, while Tesco lists 0.90g per 100g drained for its 3x80g spring-water product.

Compare the salt declaration on the exact tin, using the same measurement basis, and check how much you plan to serve.
Overlooking the rest of the dish

Barbecue sauce, mayonnaise, cheese and seasonings can add salt even when the tuna you choose has a lower declared value. The NHS advises checking sauce labels when assessing salt in a meal.

Check the labels of additions to your wrap or salad; herbs, garlic, chilli or lemon can provide flavour without adding table salt.
Judging portions by tin size alone

The quantity after draining may differ from the stated tin size: Tesco lists its 3x80g spring-water pack as 3x56g drained.

Check the drained weight when deciding how many tins you need for shared dishes.
Ignoring instructions after opening

Storage instructions differ by product. Sainsbury's says to refrigerate its opened tuna in a non-metallic container and use it within one day; the checked John West No Drain product says to consume it within two days of opening.

Follow the storage and use instructions on the tin you actually open.

Brands to compare for this meal

Sainsbury's

Its 4x145g Tuna Chunks in Spring Water is a reference point when the tuna’s declared salt content is the first consideration.

Sainsbury's lists 0.12g salt per 100g drained and 0.06g per stated half-can serving for this product.
Check the current pack: product details can change, and its instructions say to use opened contents within one day.

Tesco

Its 3x80g Tuna Chunks in Spring Water provides a smaller-tin multipack to compare for portions.

Tesco states that the pack contains 3x56g of drained tuna.
This exact product lists 0.90g salt per 100g drained; check the current label because ingredients and nutrition can change.

John West

Its No Drain spring-water 3x100g product is an option when less liquid handling matters for wraps or salads.

The product listing describes it as ready to eat without draining.
The same listing states 0.80g salt per 100g, so check its nutrition panel rather than treating the format as a lower-salt claim.

Princes

Princes offers spring-water tuna chunks and a separate drained-tuna range.

Princes describes its drained range as ready to use.
Princes lists 0.85g salt per 100g drained for its spring-water chunks; check the nutrition panel of the particular drained variant separately.

M&S

Its 160g Tuna Chunks in Spring Water is another labelled product to compare for a barbecue dish.

M&S lists tuna and spring water as ingredients and 0.75g salt per 100g for this product.
Check the pack for current details and the basis of its salt declaration before comparing it with drained values.

Asda

Its 145g Tuna Chunks in Spring Water is a single-tin option for portion comparisons.

Asda lists tuna and spring water as the ingredients of this product.
The listing states 0.90g salt per 100g drained; spring water is not, by itself, a lower-salt indication.

Questions about tinned tuna

Does spring-water tuna automatically have less salt?

No. For their specified products, Sainsbury's lists 0.12g salt per 100g drained and Tesco lists 0.90g per 100g drained. Compare the exact tins’ nutrition panels on the same basis rather than choosing by packing liquid alone.

What else should I check for salt in a tuna barbecue meal?

Check the labels of sauces, mayonnaise, cheese and seasonings alongside the tuna. The NHS notes that sauces can contribute salt and suggests herbs, spices, garlic, chilli or lemon as ways to add flavour without adding table salt.

How should I store tuna left over after opening a tin?

Follow the instructions for your exact product. Sainsbury's says to transfer leftovers from its checked tuna to a non-metallic container, refrigerate and use within one day; the checked John West No Drain product says to consume opened contents within two days.

Which label details matter when choosing tinned tuna?

Check the salt declaration and its measurement basis, ingredients and fish allergen information, and the date and storage instructions on the pack. GOV.UK food-labelling guidance identifies ingredients, including allergens, and a best-before or use-by date among the information given for pre-packed food.
