Who is this for?

Students planning several lecture-day lunches

If you use tuna in sandwiches, wraps or salads, drained weight and the number of tins help you judge how much tuna is available across your planned lunches.

Students eating away from a kitchen

A no-drain tin avoids a draining step when there is no convenient sink. A chunks-and-flakes format is another option when making a sandwich filling.

Students comparing packing media

Spring water, brine and sunflower oil give you different ingredient and nutrition labels to consider. Choose the exact tin for the lunch you intend to make rather than treating every tuna product alike.

What should you check?

Start with the usable amount of tuna and your lunch plans, then check the packing medium and what happens to any leftovers.

PriorityWhat to checkYour needs
Usable amount Check drained weight as well as net tin weight. For multipacks, check the size and number of individual tins. One tin needs to cover my lunch, or I can use separate tins across several lecture days.
Packing medium Read the ingredients and nutrition panel for the exact variant. Princes lists 99 kcal for its spring-water chunks and 180 kcal and 9.5g fat for its sunflower-oil chunks per 100g; check each label’s measurement basis when comparing products. If I am adding my own dressing, spring water may suit the recipe. If I want tuna packed in oil, I will account for that ingredient and its labelled nutrition values.
Preparation and texture Check whether the tin is labelled no-drain and whether it contains chunks, steaks or a chunks-and-flakes mix. Do not assume a spring-water multipack is no-drain. With no convenient place to drain a tin between lectures, I would prefer a labelled no-drain format; for a sandwich, texture also matters.
Leftovers and labels Read the fish allergen declaration and the exact pack’s instructions after opening. The Tesco brine tin and M&S spring-water chunks instruct you to transfer leftovers to a suitable container, refrigerate them and use them within two days. I can finish a tin at lunch, or I have a way to refrigerate the remainder as its label directs.

Common buying mistakes

  • Equating tin size with the amount of tuna

    Net weight includes the packing liquid. Tesco lists 102g drained weight for its 145g Tuna Chunks in Brine tin, so those figures answer different questions.

    Use drained weight when deciding how much tuna a tin provides for lunch.

  • Treating water-packed and oil-packed tuna as interchangeable

    Princes lists 99 kcal per 100g for its spring-water chunks and 180 kcal and 9.5g fat per 100g for its sunflower-oil chunks. The packing medium changes the labelled nutrition profile.

    Choose the medium for your recipe, then compare the exact products’ nutrition panels on the same basis.

  • Opening more tuna than you can use

    An opened tin is not a cupboard item. Tesco and M&S instruct shoppers to transfer leftovers, refrigerate them and consume them within two days for the cited products.

    Choose a tin you expect to finish at lunch unless you can follow its leftover-storage instructions.

  • Counting tinned tuna as oily fish

    The NHS states that fresh and canned tuna do not count as oily fish.

    If you are using the NHS fish guidance to plan meals, keep that distinction in mind rather than counting a tuna lunch as the oily-fish portion.

Relevant brand ranges

These ranges illustrate different formats and label details; a brand name alone does not settle which tin fits a particular lunch.

Tesco

Tesco lists own-label tuna in individual tins, larger tins and multipacks, including brine and spring-water chunks.

  • Its 145g Tuna Chunks in Brine tin lists 102g drained weight and 1.00g salt per 100g drained.

  • Its spring-water chunks list tuna and spring water as ingredients; its sunflower-oil chunks also list oil and salt.

Questions about lecture-day lunches

Why check drained weight rather than just tin size?

Drained weight tells you how much tuna remains after the packing liquid is removed. Tesco, for example, lists 102g drained weight for its 145g Tuna Chunks in Brine tin; use the drained figure when planning how much tuna a lunch will contain.

Is spring-water tuna always the right choice for lunch?

No single packing medium fits every recipe. Princes’ spring-water chunks list tuna and water as ingredients, while its sunflower-oil chunks contain oil and have different labelled energy and fat values. Choose the ingredients and texture you want, and compare nutrition panels on the same measurement basis.

How should I store tuna left over from lunch?

Follow the instructions on the exact tin. Tesco’s cited brine tin and the cited M&S spring-water chunks direct you to transfer unused tuna to a suitable container, refrigerate it and consume it within two days; an opened tin is not a cupboard item.

Does tinned tuna count as oily fish?

No. The NHS states that fresh and canned tuna do not count as oily fish, so a tinned-tuna lunch does not fulfil the oily-fish part of its fish guidance.

Which label and frequency checks matter for some shoppers?

Tuna contains fish, so anyone with a fish allergy needs to check the allergen label and avoid a product containing it. For people who are pregnant or trying for a baby, the Food Standards Agency cites NHS guidance of no more than four cans of tuna a week or two tuna steaks a week; that limit applies to those groups, not every shopper.
