Who this choice matters to

Weekly meal planners watching salt

If you use tinned tomatoes in several meals, comparing salt per 100g gives you a consistent way to choose between similar tins. Consider the other ingredients and any salt you add while cooking, too.

Regular users of chopped tomatoes

A multipack may fit repeated sauces, curries, soups or stews if you have room to store it and expect to use the tins. Napolina’s checked 4 x 400g chopped-tomato pack declares 0.10g salt per 100g.

Cooks choosing tomatoes for texture

Mutti Polpa offers a finely chopped tomato base for recipes where that texture matters. Mutti declares 0.30g salt per 100g and lists salt as an ingredient, so compare its label with plainer chopped options if salt is the priority.

What to check before buying

Start with the salt figure for the format your recipe needs, then decide how many tins you will use.

Priority What to check Your needs
Reading the label Compare salt per 100g on similar tins. Use front-of-pack traffic-light labelling as a prompt to read the nutrition panel, not as a substitute for it. I want to compare the figures rather than rely on the front of the tin. In the Food Standards Agency and Ipsos Northern Ireland’s 2024 survey, 49% of 611 people interviewed in Northern Ireland between 16 September and 23 November said they actively use traffic-light labelling when shopping for food. That measures label use, not interest in lower-salt tomatoes.
Salt in the dish Tesco Groceries lists 0.09g salt per 100g for its Italian Chopped Tomatoes; Napolina lists 0.10g for its chopped tomatoes, and Mutti lists 0.30g for Polpa. Check the current tin and the salt contributed by other ingredients. If I cook with tomatoes often, I want a lower declared salt figure without overlooking stock, cheese, sauces or seasoning elsewhere in the meal.
Tomato texture Check whether the recipe calls for chopped pieces, finely chopped pulp or whole peeled tomatoes. Mutti’s Polpa contains salt as an ingredient and declares 0.30g salt per 100g. For a particular sauce, the texture may matter more to me than choosing the lowest salt figure among the checked chopped tins.
Pack quantity Count the tins and check their size: the checked Napolina chopped-tomato multipack contains 4 x 400g. Consider storage space and how often you cook with tomatoes. A multipack suits my shop if I will use the tins across several meals; otherwise, a single tin may better match my plans.

Buying pitfalls

  • Treating texture or origin as a salt guide

    The checked Napolina chopped tomatoes declare 0.10g salt per 100g, while Mutti Polpa declares 0.30g. A description such as finely chopped does not tell you the salt figure.

    Compare salt per 100g first when that is your priority, then choose the texture your recipe needs.

  • Assuming “reduced salt” means salt-free

    A reduced-salt claim describes a comparison; it does not tell you that the tin contains no salt.

    Read the declared salt per 100g and consider how much tomato and other ingredients you will use in the dish.

  • Choosing a multipack without a plan to use it

    Four tins are useful for repeated cooking, but the pack still needs cupboard space and may exceed what you need for one week.

    Match the quantity to the meals you expect to make and check the dates on the tins.

  • Using an old label figure for a repeat purchase

    Ingredients and nutrition declarations can change, so a previously checked figure may not describe the tin in your basket.

    Read the current pack’s salt-per-100g declaration when making it a regular weekly purchase.

Questions about choosing and using tins

Does “reduced salt” mean a tin is salt-free?

No. “Reduced salt” is comparative wording, not a statement that the tin contains no salt. Read the declared salt per 100g to see the amount in the product you are buying.

How can I compare tins quickly during a weekly shop?

Compare salt per 100g on tins with a format that suits your recipe. Tesco Groceries lists 0.09g for its Italian Chopped Tomatoes, Napolina lists 0.10g for its chopped tomatoes, and Mutti lists 0.30g for Polpa; confirm the current label before making a repeat purchase.

Should I add salt when cooking with tinned tomatoes?

Taste the dish before deciding whether to add any. Salt from stock, cheese, cured meat or sauces also contributes to the finished meal; the NHS advises considering salt already in food as well as salt added during cooking.

What should I do with tomatoes left after opening a tin?

Follow the storage and time-after-opening instructions on that product’s pack. If it directs you to transfer the contents to another container, follow that instruction rather than keeping them in the opened tin.
