First-time cupboard stockers
If you want a plain tomato base while paying attention to sugar, compare total sugars per 100g and read the ingredients. A brand name or a sweet flavour does not replace the nutrition label.
Who is this for?
One- or two-person cooks
A smaller tin may fit a meal more closely than a standard 400g tin. Sainsbury's lists a 227g chopped-tomato option; whichever size you choose, plan how you will store any leftovers.
Cooks choosing a sauce texture
Napolina describes its chopped tomatoes as chunky, while Mutti describes Polpa as finely chopped pulp and juice. Choose according to whether you want visible pieces or a finer tomato base.
What should you check?
Start with the nutrition figures for the exact tin, then decide which ingredients, texture and quantity fit the meals you plan to cook.
| Priority | What to check | Your needs and label use |
|---|---|---|
| Reading labels | Read total sugars per 100g, even if the pack also shows a figure per serving. The NHS guide describes 5g sugars or less per 100g as low for foods. | I want to compare tins on the same basis, not judge them by a traffic-light colour alone. In the Food Standards Agency and Ipsos Northern Ireland's 2024 survey, 49% of 611 Northern Ireland respondents interviewed from 16 September to 23 November said they actively used traffic-light labelling when shopping for food; that figure measures general label use, not tomato preferences. |
| Ingredients | Check whether you are buying plain tomatoes or a prepared or flavoured product. Read the ingredient list alongside the sugars figure; they answer different questions. | For everyday sauces, I want to know what else is in the tin rather than assuming all tomato products have the same recipe. |
| Salt | Compare salt per 100g on the exact products. The NHS guide describes 0.3g salt or less per 100g as low for foods. | Sugar is not my only label check; I also want to see the declared salt before choosing a tomato base. |
| Texture | Look for standard chopped pieces or a finely chopped pulp-and-juice format. Consider whether your recipe calls for pieces or a finer base. | A chunky stew calls for a different texture from a sauce in which I would rather not have large tomato pieces. |
| Tin size | Compare the amount per tin with the portions you plan to make. For multipacks, check whether you have room and expect to use the tins. | If I am cooking a small meal, a 227g tin may leave less to store; for repeated cooking, several 400g tins may be more useful. |
Common buying mistakes
-
Treating ‘reduced sugar’ as the same as low total sugars
A reduction describes a comparison; it does not tell you the tin's total sugars figure on its own.
Compare total sugars per 100g on the tins you are considering. The NHS guide gives 5g or less per 100g as its low-sugar figure for foods.
-
Comparing different serving sizes
The amount of sugar in a whole 227g tin cannot be compared directly with that in half a 400g tin to judge which product has less sugar by weight.
Compare sugars and salt per 100g first; choose the tin size separately according to your planned portions.
-
Assuming every chopped tin has the same texture
Napolina describes a chunky chopped product, whereas Mutti describes Polpa as finely chopped pulp with juice. The difference matters if you want pieces to remain visible in a sauce.
Check the product description for the cut and texture that suit your recipe.
-
Buying more than you plan to use
A partly used tin leaves tomatoes to store after cooking, and instructions for opened products can differ.
Check the storage directions on your tin. Transfer leftovers to a suitable covered non-metallic container, refrigerate them and follow the product's stated period for use.

Frequently asked questions
How do I compare sugar in two tins of tomatoes?
Compare total sugars per 100g on the exact products, rather than figures for different serving sizes. The NHS guide describes 5g sugars or less per 100g as low for foods; the plain chopped products listed by Sainsbury's, Napolina, Asda, M&S and Tesco range from 3.5g to 4.0g per 100g.
Do I need a ‘reduced sugar’ claim to choose a tin?
No. A claim on the front of a tin is not necessary for comparing ordinary tomatoes: read the declared total sugars per 100g and the ingredients on the products you are choosing. A comparison about reduction and a low total-sugars figure answer different questions.
Should I check salt as well as sugar?
Yes, if salt matters to your choice, compare it per 100g on the same tins. The NHS guide describes 0.3g salt or less per 100g as low for foods; check the exact label rather than carrying a figure over to a flavoured or prepared tomato product.
What should I do with tomatoes left in an opened tin?
Transfer leftovers to a suitable covered non-metallic container and refrigerate them. Follow the storage period stated on your product: the supplied product guidance gives four days for Asda Chopped Tomatoes, three days for M&S Chopped Italian Tomatoes and two days for the Sainsbury's 227g tin.
