Who this helps

Salt-conscious festival campers

If you are watching salt across snacks, ready meals and sauces, compare the nutrition labels of the exact tins you might take. Packing tuna in water or making it no-drain does not establish its salt content.

Solo campers with limited preparation space

A no-drain pack can avoid dealing with liquid at the campsite. A pack you expect to finish in one sitting also avoids needing to chill unused tuna.

People planning group meals

Separate tins or a larger can may suit different meal plans. Match the amount you open to what the group will eat promptly, especially when chilled storage is uncertain.

What to check when buying

Compare salt on a like-for-like label basis first, then choose a format that fits the preparation space and the number of people eating. The NHS advises choosing tinned fish in water rather than brine when cutting down salt, but the exact product label still matters.

Concern What to check Who this matters to
Salt across the day Compare salt per 100g on the exact tins, noting whether figures refer to drained product. Check salt per can if you plan to eat the whole pack. If I am taking snacks and sauces as well as tuna, I want to know how much salt the tin adds to my day; about 50% of consumers put salt control first.
Mess and opened food Check whether the exact pack is no-drain and whether you can finish it without needing to refrigerate leftovers. With little space to prepare food or dispose of liquid, I want a pack I can open and finish easily. Low-mess, single-meal use comes first for about 30% of consumers.
Portions for the group Check the size and number of tins against the meal plan, and read the after-opening storage instructions. When several people are sharing a meal, I want enough tuna without opening more than we can use; about 20% of consumers make portion planning their main concern.

Common buying mistakes

  • Assuming spring water means reduced salt

    Spring-water tins can have different salt figures. Tesco Groceries lists John West no-drain chunks at 0.80g salt per 100g and its no-drain tuna steak at 1.0g per 100g.

    Compare the exact packs on the same per-100g basis, then check the per-can figure if you will eat a whole tin.

  • Opening more tuna than you can use

    Tesco Groceries and Ocado list John West and M&S products whose labels instruct you to refrigerate unused contents and eat them within 2 days. That matters when a festival camp has no dependable chilled storage.

    Choose a tin you can finish at one meal, or open a larger can when the group is ready to share it.

    Otherwise, unused tuna may have to be discarded.

  • Checking the tuna but not the additions

    Sauces and seasonings can contribute salt alongside the tuna. The NHS says adults should have no more than 6g of salt a day in total.

    Check the labels of additions before combining them with the tuna, rather than judging the meal by the tin alone.

Brands to consider

John West

Its listed no-drain spring-water chunks and smaller tuna steaks are worth examining when draining and pack size matter at a campsite.

  • Tesco Groceries lists the no-drain chunks at 0.80g salt per 100g and the 60g no-drain steak at 0.6g salt per can, or 1.0g per 100g.
  • These figures apply to those products, not the whole range. Their labels instruct you to refrigerate unused contents and consume them within 2 days.

Tesco

Tesco Groceries lists own-label chunks in spring water, brine and sunflower oil, alongside tuna steaks, allowing you to compare formats.

  • The range includes separate tins and multipacks for different meal plans.
  • Check the nutrition panel of the particular product before making a salt comparison; the packing medium alone is not its salt figure.

Princes

Tesco Groceries lists Princes chunks and steaks in several packing media, including spring water, brine and sunflower oil.

  • Listed formats include 4 x 145g chunk packs and 3 x 110g drained tuna-steak packs.
  • Compare the exact pack label before choosing one for its salt content; these format listings do not establish a reduced-salt option.

M&S

Its listed spring-water tuna steaks include a multipack and a larger can that may suit a meal shared promptly.

  • Ocado lists 0.75g salt per 100g drained product for the multipack and 0.83g per 100g drained product for a 200g can.
  • Both are packed in spring water, yet have distinct salt figures. Their labels instruct you to refrigerate unused contents and eat them within 2 days.

Questions about camping with tinned tuna

Is spring-water tuna always lower in salt than tuna in brine?

No: the packing medium alone cannot tell you the salt content of the exact products you are comparing. The NHS recommends choosing tinned fish in water instead of brine when cutting down salt, while Tesco Groceries lists John West spring-water examples at 0.80g and 1.0g salt per 100g. Compare their nutrition panels on the same basis.

How much salt should adults have in a day?

The NHS says adults should have no more than 6g of salt a day. Include salt already in packaged food and anything added to the tuna meal when considering that total.

Can I leave opened tuna in my tent for another meal?

Do not leave unused tuna in a tent when its pack instructs you to refrigerate it. Tesco Groceries and Ocado list John West and M&S products whose labels call for refrigeration after opening and consumption within 2 days. Without dependable chilled storage, choose a tin you can finish at one meal.

Are there limits on 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 than other fish. This weekly guidance matters when planning tuna alongside other meals, whether camping or at home.
