For a low-FODMAP meal, start with unflavoured tinned tuna and check the current ingredient list for sauces or seasonings; Monash FODMAP identifies unflavoured canned tuna as an option. Choose chunks if you plan to flake the fish, steak-style tins if you want larger pieces, or a no-drain tin if avoiding that preparation step matters. A tinned product described as a steak or fillet is not fresh raw fish.
If you are following a low-FODMAP restriction or personalisation phase, a plain tin is easier to assess than one with a marinade or sauce. Monash FODMAP identifies unflavoured canned fish, including tuna, as an option, but says food suitability should not be guessed from its name alone.
If you want tuna to hold its shape on a salad or jacket potato, compare steak-style tins with chunks. The Princes, M&S and Asda spring-water steak products provide examples of this tinned format; the wording does not establish that the fish is fresh.
If preparation time or portion planning matters, look at no-drain tins, single tins and multipacks. Check each product’s ingredients against your own meal plan, then choose a pack size you can use and store as its label directs.
Check the ingredients before choosing a piece size or pack format. A steak-style tin changes the presentation, while a no-drain tin changes the preparation; neither replaces the ingredient check.
| Concern | What to check | Who this matters to |
|---|---|---|
| Plain ingredients | Read the current ingredient list. Check flavoured tins for sauces, marinades and seasonings rather than relying on the flavour name. | When keeping added flavours separate during a low-FODMAP restriction, I want to assess the tuna without also assessing a sauce; about 36% of consumers put plain ingredients first. |
| Piece size | Compare chunks with steak-style pieces, and check whether the tin needs draining. | For a salad or jacket potato, I want pieces that remain more intact instead of fine flakes. Larger-piece texture is the primary concern for about 22% of consumers. |
| Salt and packing liquid | Check the packing liquid and compare salt figures on the same basis, such as per 100 g drained. | If I am comparing two plain-looking tins, I want their nutrition panels to use the same weight basis before choosing. About 21% of consumers mainly prioritise that comparison. |
| Portions and storage | Check the number of tins, net and drained weights, and the instructions for leftovers after opening. | A no-drain tin could simplify my lunch, while a larger pack must fit the meals I have planned. Portion and preparation needs come first for about 21% of consumers. |
Monash FODMAP identifies unflavoured canned tuna as an option, but a marinade, sauce or seasoning changes the ingredient list you need to assess.
Start with an unflavoured tin if you want a simpler label. Read the can before using a flavoured version, and add only ingredients that fit your own plan.
Princes, M&S and Asda sell steak-style tuna in tins. The term describes the canned product’s form, not fresh raw fish.
Choose a steak-style tin for its larger-piece presentation. If your recipe calls for fresh raw tuna, look in the chilled fresh-fish category instead.
One tin may state values per 100 g drained while another uses an as-sold weight or a serving. Can size alone will not make those figures comparable.
Check the basis printed beside each nutrition figure and the drained weight before comparing salt or other declared values.
Whether a plain tin fits a low-FODMAP meal is separate from the NHS’s tuna intake guidance for people who are pregnant or trying for a baby.
The NHS advises no more than four cans of tuna a week or two tuna steaks a week for that group.
Its spring-water chunks and no-drain line offer different preparation formats.
Its Tuna Steaks in Spring Water provide a steak-style option with a short ingredient list.
Its own-label spring-water chunks include a 400 g tin and multipack formats.
Its own-label 145 g spring-water chunks are another plain-format option to assess.
Its range includes spring-water chunks and a no-drain tuna steak.
Its spring-water range includes both chunks and an already-drained tuna steak.
These selections are tinned tuna chunks in spring water, including a no-drain format. Use the ingredient and pack checks above when choosing among them; chunks are not a substitute for fresh raw fillets.

A four-tin chunk format for planned cupboard meals when you intend to flake the tuna. Check the current can label for ingredients and the instructions for any leftovers.

A single chunk-style tin for a meal where a multipack is unnecessary. Read its current ingredient list and check how the nutrition values and drained weight are stated.

A chunk-style multipack to consider when stocking several meals. Confirm the number of cans and total pack weight before ordering: the product title indicates six packs, while the listed net quantity is 145 g.

The no-drain chunk format suits a quick meal when draining a tin would be inconvenient. Check the current ingredients and the basis of any salt figure on the can before comparing it with drainable tuna.

A single chunk-style tin for a cupboard meal. Confirm the brand on the physical label before buying: the product title says Topical Sun, while its description says Tropical Sun. Check the can’s ingredients and nutrition basis too.
Monash FODMAP identifies unflavoured canned tuna as an option. Check the specific tin’s ingredients, because a flavoured recipe or sauce may contain additions that need separate assessment.
No. On a shelf-stable tin, steak or fillet wording is a cue to the product’s pieces and presentation, not a guarantee of fresh raw fish. Choose the chilled fresh-fish category if that is what your recipe requires.
Follow the instructions on that can. Tesco’s multipack listing, for example, says to transfer unused tuna to a non-metallic container, cover and refrigerate it, then consume it within two days.
Yes. The NHS advises people who are pregnant or trying for a baby to have no more than four cans of tuna a week or two tuna steaks a week. This guidance is separate from whether a product’s ingredients fit a low-FODMAP meal.
No. Cambridge University Hospitals NHS Foundation Trust describes restriction as temporary, and Gloucestershire Hospitals NHS Foundation Trust explains the importance of reintroducing FODMAP-containing foods afterwards. Follow the plan advised for your circumstances rather than treating a short ingredient list as a complete diet plan.
