For a roast dinner, a standard chopped-tomato tin can be a low-salt choice if its label shows 0.3g salt or less per 100g, the NHS threshold for low-salt foods. Choose a no-added-salt tin if you want to control the tomato dish’s seasoning yourself, but compare its per-100g figure too: it need not contain zero salt, and gravy, stock and other accompaniments still need separate consideration.
If the meal includes gravy, stock or sauces, comparing the tomato tin separately makes it easier to decide where to add seasoning. The NHS advises checking labels and paying attention to sauces, including gravy granules.
Chopped tomatoes offer visible pieces for a roast vegetable side or sauce. Napolina describes its chopped tomatoes as chunky and suited to thick sauces; you can simmer a tomato mixture if you want less liquid.
If you want to add your own herbs or garlic, compare the ingredient lists as well as the salt figures. The cited M&S and Sainsbury’s products provide examples with stated ingredients and per-100g nutrition.
Compare salt and ingredients first, then choose the texture and opened-tin storage instructions that fit your cooking plans.
| Priority | What to check | Your needs |
|---|---|---|
| Salt across the meal | Compare salt per 100g, not just the front-of-pack wording. The NHS defines low salt as 0.3g or less per 100g; check stock and gravy separately. | I want to decide how much seasoning goes into the tomato dish when the roast has other salty components. |
| Tomato texture | Check whether the tin contains chopped pieces or finely chopped tomatoes. Simmer a sauce if you want to reduce its liquid. | For a chunky vegetable accompaniment, I would choose chopped pieces; for a finer sauce, I would look at finely chopped tomatoes. |
| Added seasoning | Read the ingredients for added salt or flavourings, then check the nutrition figure even on a no-added-salt tin. Mr Organic describes its chopped tomatoes as having no added salt and lists 0.03g salt per 100g. | I would rather add herbs, garlic or pepper myself than assume a flavoured tin has the same ingredients as a plain one. |
| Leftovers | Follow the particular pack’s opened-tin instructions. Sainsbury’s specifies a non-metallic container, refrigeration and use within 2 days for its cited tin; M&S specifies refrigeration and use within 3 days for its cited product. | If I will use only part of a tin while preparing several dishes, I need to know how to store the rest. |
Front-of-pack wording does not give you a like-for-like figure across tins. The NHS low-salt definition is based on salt per 100g.
Compare the per-100g panels, then read the ingredients if avoiding added salt matters to you.
A low-salt tomato tin does not determine the salt content of gravy, stock or sauces served alongside it. The NHS identifies sauces, including gravy granules, as ingredients worth checking.
Consider those ingredients separately and taste the tomato dish before adding salt.
A garlic, herb or chilli variant can have a different ingredient list and salt figure from a plain tin.
Check the label of the exact flavour you intend to buy rather than using the plain product’s figures.
The tin you buy needs to match the ingredients and nutrition figures on which you based your choice.
Check its current label, particularly when comparing products by small differences in salt per 100g.
These examples show why the salt figure needs checking on the particular product, not inferred from its brand or texture.
Its plain chopped tomatoes are a reference point for a chunky tomato sauce.
Polpa finely chopped tomatoes are an option when you want a finer tomato texture.
The cited own-label chopped-tomato tins provide standard and organic product-label comparisons.
Its cited Chopped Italian Tomatoes offer a plainly labelled ingredient and nutrition comparison.
Tesco Groceries lists own-label chopped tomatoes alongside Napolina and Mutti tomato products.
These Napolina chopped-tomato multipacks are options for making a tomato sauce or accompaniment alongside a roast; choose a pack quantity you can use and check its current nutrition label when salt control matters.

The NHS defines a low-salt food as one with 0.3g salt or less per 100g. Compare that figure on the tins you are considering rather than comparing different suggested portions.
No. A no-added-salt product can still list salt in its nutrition information: Mr Organic describes its cited chopped tomatoes as having no added salt and lists 0.03g salt per 100g.
Choose chopped pieces if you want visible tomato texture in a side or sauce, or finely chopped tomatoes if you prefer a finer texture. Check salt independently: Waitrose & Partners lists the cited finely chopped Mutti product at 0.30g per 100g.
Start by comparing the tin’s salt per 100g, then season the tomatoes to taste before adding salt. Check gravy, stock and sauces separately; the NHS advises checking labels and identifies sauces, including gravy granules, as ingredients to watch.
Follow the instructions on your pack. Sainsbury’s says to transfer the contents of its cited tin to a non-metallic container, refrigerate and use within 2 days; Marks & Spencer says to refrigerate its cited product after opening and eat it within 3 days.
