Quick lunch planners
If you use tinned tomatoes as the base for soup, beans or pasta sauce, choose a cut that suits the dish and check the ingredients and salt on the tin you buy.
Who is this for?
Multipack cupboard stockers
If you cook with tomatoes regularly, compare single tins and multipacks by how many you expect to use. Check the after-opening instructions too, particularly if one tin lasts more than one meal.
People following a prescribed low-potassium diet
General lunch suggestions cannot establish whether a tomato product fits an individual diet plan. North Bristol NHS Trust advises people managing potassium to seek guidance from their dietitian.
What should you check?
Start with the cut your usual lunch needs, then compare the label and pack instructions for the exact product.
| Priority | What to check | Your needs |
|---|---|---|
| Ingredients | Read the ingredient list for added salt, sugar or flavourings. For a vegetable portion, the NHS says 80g of canned vegetables counts as one of 5 A Day. | I want a tomato base for lunch and need to know what else is in the tin. |
| Salt | Compare the salt figure per 100g on the exact product, including when choosing between plain and flavoured versions. | Salt matters to my choice, so I do not want to assume two tomato tins have the same label. |
| Cut | Choose chopped, finely chopped or whole plum tomatoes according to the texture you want and whether you are willing to break up the tomatoes during cooking. | For a smoother sauce, I would rather start with a finer cut; for another dish, pieces or whole tomatoes may suit me. |
| Leftovers | Follow the tin’s instructions for transferring, refrigerating and using the contents after opening. Sainsbury’s, for example, instructs shoppers to use its chopped tomatoes within two days after transfer to a non-metallic container. | If I use only part of a tin at lunch, I need a plan for the rest. |
| Pack size | Check the number and size of tins in a multipack against how often you cook with tomatoes. Read the after-opening directions for each product. | A larger cupboard supply suits me only if I expect to use the tins. |
Common buying mistakes
-
Assuming every plain tomato tin has the same ingredients
Ingredient lists differ: Mutti lists tomato and salt for its finely chopped Polpa, while ASDA lists tomatoes, concentrated tomato juice and citric acid for its chopped tomatoes.
Read the exact product’s ingredients and salt per 100g rather than choosing by brand or tomato cut alone.
-
Choosing a multipack without planning for opened tins
Once a tin is open, its storage instructions matter even if unopened tins are kept in the cupboard. Sainsbury’s tells shoppers to transfer its chopped tomatoes to a non-metallic container, refrigerate them and use them within two days.
Choose a pack size you expect to use, and follow each tin’s directions for any leftovers.
Unused opened contents may go to waste if you cannot use them within the stated period.
-
Reading “best before” as “use by”
GOV.UK distinguishes the two: a best-before date relates to quality, while a use-by date relates to food safety.
Read the date wording on the tin and follow its storage instructions, including the separate directions that apply after opening.
-
Applying general lunch advice to a prescribed diet
A general choice of tinned tomatoes does not establish whether the product or portion fits a prescribed low-potassium diet.
If this applies to you, ask your dietitian how tomato products fit your individual plan, as North Bristol NHS Trust advises.

Frequently asked questions
Do tinned tomatoes count towards 5 A Day?
Yes. The NHS says 80g of canned vegetables counts as one portion of 5 A Day. Check the serving information on the particular tin if it makes a portion claim.
Should I choose chopped, finely chopped or whole plum tomatoes?
Choose the cut that fits how you cook: standard chopped tomatoes retain pieces, finely chopped tomatoes give a finer cut, and whole plum tomatoes can be broken up for a sauce. Check the ingredients and salt on the exact product rather than assuming the cuts have identical labels.
How should I store tomatoes after opening a tin?
Follow that product’s instructions. Sainsbury’s says to transfer its chopped tomatoes to a non-metallic container, refrigerate them and use them within two days; do not assume the same period applies to another tin.
What does “best before” mean on a tomato tin?
A best-before date concerns quality, according to GOV.UK; it is different from a use-by date, which concerns food safety. Check the tin’s date wording and follow its storage directions, especially after opening.
Can I use tinned tomatoes on a prescribed low-potassium diet?
Do not decide from general lunch guidance alone. If you have been prescribed a low-potassium diet, ask your dietitian how tomatoes and tomato-based meals fit your individual plan, as North Bristol NHS Trust advises.
