For a Mexican-style meal where reducing salt matters, compare plain chopped tomatoes by the salt declared per 100g: ASDA Groceries lists 0.01g for its 400g tin and Marks & Spencer lists 0.02g for its 400g tin, though neither figure determines the salt content of the finished dish. Check the current tin label and the stock, sauces, seasonings and toppings you plan to add.
If you are making chilli, a bean stew or a tomato-based tortilla filling, a plain tin lets you choose how to season the tomato base. NHS advice suggests herbs, spices, garlic and chilli as alternatives to adding salt.
Comparing tins on the same per-100g basis helps you account for the tomatoes alongside the other ingredients in a meal. The NHS advises adults to have no more than 6g of salt a day, including salt already present in food.
A quick recipe may include several packaged ingredients besides tomatoes. Check the labels on stock cubes and bottled sauces too; the NHS identifies both as ingredients worth checking when reducing salt.
Compare the tomato tins on a common basis, then consider how much of a tin the recipe uses and what else goes into the pan.
| Priority | What to check | Your needs |
|---|---|---|
| Salt in the tomatoes | Compare salt per 100g on the specific tins. Cambridge University Hospitals NHS Foundation Trust recommends this basis for comparing labels; check the current pack rather than relying on front-of-pack wording alone. | I want a tomato base whose declared salt fits the meal I am making, without assuming all plain chopped tomatoes have the same figure. |
| Amount used | Check the tin size and the label’s serving information. A half-tin figure does not describe the contribution from a whole tin. | If my chilli uses all 400g, I need to account for the whole tin rather than just the stated serving. |
| Other ingredients | Read the salt labels on stock, bottled sauces and seasoning blends. The NHS suggests herbs, spices, garlic and chilli for flavour instead of routinely adding salt. | I may choose a lower-salt tomato tin, but I also want to know what the stock, sauce and toppings add to the dish. |
The cited ASDA Groceries listing declares 0.01g salt per 100g for ASDA Chopped Tomatoes 400g, while its Mutti Finely Chopped Tomatoes 400g listing declares 0.30g per 100g. Those figures describe the named products, not every tin from either brand.
Compare the per-100g declaration on the exact tin you intend to use.
A lower-salt tomato base does not determine the salt content of stock, bottled sauces or toppings. The NHS advises checking sauces and stock cubes when reducing salt.
Read those labels before seasoning the finished dish; chilli, spices, garlic and herbs can add flavour without adding table salt.
A label may give salt for half a tin, while a sauce or chilli uses the whole tin. In that case, the serving figure alone understates what the tomatoes contribute to the recipe.
Use salt per 100g to compare products, then account for the quantity you actually add.
Storage directions differ between the cited products: ASDA Groceries lists two days after opening for Napolina Chopped Tomatoes, Marks & Spencer lists three days for its Chopped Italian Tomatoes, and ASDA Groceries lists five days for Mutti Finely Chopped Tomatoes, with refrigeration specified for each.
Follow the directions on your tin. Marks & Spencer also instructs shoppers to transfer its opened tomatoes to a non-metallic container.
These declarations apply to the named UK listings, not to every tomato product made by each brand.

The finely chopped format is worth considering when you want that texture in a tomato sauce. This pack contains four 400g tins; check the current salt declaration against your other options and follow the opened-tin storage directions.
Start with salt per 100g so that different tins are compared on the same basis, as Cambridge University Hospitals NHS Foundation Trust advises. Then check the tin size and serving information to account for the amount your recipe uses.
No: the tin is only one ingredient. Check stock cubes, bottled sauces, seasonings and toppings as well; the NHS advises checking sauces and stock and suggests herbs, spices, garlic and chilli instead of routinely adding salt.
Not on the cited UK product declarations: ASDA Groceries lists Mutti Finely Chopped Tomatoes 400g at 0.30g salt per 100g and ASDA Chopped Tomatoes 400g at 0.01g. Marks & Spencer lists its Chopped Italian Tomatoes 400g at 0.02g per 100g. Compare the current labels when buying, especially if you are choosing a different pack or variant.
Follow the directions on that tin rather than using one time limit for every product. The cited ASDA Groceries listing says to refrigerate opened Napolina tomatoes and use them within two days; Marks & Spencer says to transfer its opened tomatoes to a non-metallic container, refrigerate and eat within three days.
Use listings to compare products, but check the current tin label before using its salt figure or ingredient list. Sainsbury's warns that products and ingredients can change, so an earlier online description may not match the pack in hand.
