For regular high-protein meals, choose a tuna multipack by its usable portions, not just its can count or outer pack weight. Spring-water chunks provide a flexible base; compare protein on the label’s stated basis, check the drained weight of each can, and make sure the pack size, salt content and opened-can instructions fit your routine.
If you plan several tuna lunches or dinners, the drained amount per can and the number of cans matter more than the size of the outer pack. Check that the portions suit the meals you actually prepare and that you have room to store the unopened tins.
If you track more than protein, read the nutrition panel before choosing between spring water, brine and oil. Princes lists the same protein per 100g for its examined spring-water and sunflower-oil chunks, while its oil-packed product also lists fat and energy from the oil.
No-drain or drained-ready tuna can be useful when you want a quick portion for lunch. Check the instructions and usable quantity before assuming a smaller convenience pack will serve the same number of meals as a conventional multipack.
For high-protein meal planning, start with usable tuna per can, then decide which other consideration is most important to your routine.
| Concern | What to check | Who this matters to |
|---|---|---|
| Protein and portions | Read protein per 100g on the stated nutrition basis and find the drained weight per can. If you also track energy or fat, check the packing liquid and its nutrition panel. | If I plan protein around each meal, I need to know how much tuna I can actually serve, not just the tin’s net weight. About 38% of consumers put protein and portion planning first. |
| Stock-up practicality | Compare can count and drained quantity, then consider storage space and how often you will use the tins. | When I prepare tuna meals regularly, I want enough cans on hand without committing to more than I can use. Stock-up practicality comes first for about 31% of consumers. |
| Salt and meal fit | Compare salt per 100g on like-for-like label bases, and read the ingredients to distinguish spring water, brine and oil. | If salt or the packing liquid affects what I put in a sandwich, salad or pasta dish, the format matters before I choose a large pack. About 23% of consumers make salt and meal fit their primary concern. |
| Pregnancy-related intake | If you are pregnant or trying for a baby, account for tuna across the week. The NHS advises no more than four cans or two tuna steaks a week for this group. | If I am pregnant or trying for a baby, I need to plan how often tuna appears in my meals rather than treat a bulk pack as a daily plan. That is the primary concern for about 8% of consumers. |
Net weight includes packing liquid, so similarly sized tins need not provide the same amount of tuna. Tesco lists 56g drained tuna in each examined 80g can; a Princes 145g spring-water can listed on Joybuy has 102g drained.
Check drained weight per can and multiply it by the can count before deciding which format supplies the portions you need.
Princes lists 23.5g protein per 100g for both its examined spring-water and sunflower-oil chunks. Its sunflower-oil chunks also list 180kcal and 9.5g fat per 100g.
Read the nutrition panel for the exact packing liquid you intend to buy, particularly if energy or fat is part of your meal planning.
Salt varies between the examined products: Sainsbury’s lists 0.12g per 100g drained for its spring-water chunks, while Tesco lists 0.90g per 100g drained for its examined pack.
Compare the current labels on the same per-100g basis rather than relying on the packing liquid or brand name alone.
For people who are pregnant or trying for a baby, the NHS advises no more than four cans of tuna or two tuna steaks a week.
If that guidance applies to you, count tuna across all your meals when deciding how many tins to keep on hand.
These examples show how can size, packing liquid and label values differ across particular product lines. Check the exact pack rather than treating a brand name as a specification.
No Drain spring-water chunks are available in an examined 3 x 100g format.
Its examined range includes spring-water and sunflower-oil chunks, as well as drained-ready formats.
Its examined spring-water chunks come in a 3 x 80g pack with smaller individual portions.

A four-can spring-water format to consider for regularly planned tuna meals. The listed 125g is the can’s net weight; check its drained weight to work out the usable portion. Follow the pack’s instructions for any leftovers after opening.

The title describes a large brine multipack for frequent use. Confirm how many four-can packs are supplied and the drained weight of each can before committing storage space; do not use the stated net weight as the amount of tuna per portion.

A six-pack to consider when you plan several spring-water tuna meals. The stated 145g can size does not establish its drained portion; confirm the supplied quantity and drained weight on the listing or pack. If salt matters to your choice, check the current nutrition label.

This four-can brine pack is a smaller commitment than the separately listed multi-pack of four-can packs. Check the drained weight per can for portion planning and read the current salt figure if it affects your choice.

This smaller three-can format is worth considering when quick portions matter more to you than a larger store of tins. Check the exact pack instructions before deciding whether to drain it, and use the nutrition label’s stated basis when planning portions.
Protein alone may not settle the choice: Princes lists 23.5g protein per 100g for both its examined spring-water and sunflower-oil chunks. Its sunflower-oil product also lists 180kcal and 9.5g fat per 100g, so check the packing liquid and full nutrition panel if those figures matter to your meals.
Use drained weight to work out how much tuna the can provides, then apply the nutrition panel on its stated basis. Tesco lists 56g drained tuna in each examined 80g can, while a Princes 145g spring-water can listed on Joybuy has 102g drained.
Follow the instructions on the exact pack. The examined Tesco, Asda and M&S labels call for refrigeration and use within two days, with transfer to a suitable covered or non-metallic container where specified; other packs may give a shorter period.
Plan the total across the week rather than treating a bulk pack as a daily meal plan. 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.
No. The NHS says fresh and canned tuna do not count as oily fish in its fish guidance, so buying tuna in bulk does not replace the oily-fish portion described there.
