Cooks comparing sugars in savoury dinners
If you are making pasta sauce, chilli, soup or a casserole, the tin’s total-sugars figure gives you a basis for comparing tomato ingredients before you add anything else to the dish.
Who is this for?
Shoppers reading the ingredients list
Check “of which sugars” per 100g alongside the ingredients. As the NHS explains, naturally occurring sugars in vegetables appear in the total-sugars figure; that figure alone does not show whether sugar was added.
Cooks choosing a sauce texture
Standard chopped tomatoes leave more distinct pieces at first. Finely chopped tomatoes are worth considering when you want a more even tomato base without blending.
What should you check on the tin?
Compare nutrition on the same per-100g basis, then choose a tomato format that works for the dinner you are making.
| Priority | What to check | Your needs |
|---|---|---|
| Total sugars | Compare “of which sugars” per 100g across comparable tins. Read the ingredients to distinguish plain tomatoes from a prepared sauce; the sugars figure alone does not identify added sugar. NHS food-label guidance describes 5g total sugars or less per 100g as low. | I want to compare tomato bases without mistaking the tomatoes’ naturally occurring sugars for an added ingredient. |
| Tomato texture | Check whether the tin contains standard chopped, finely chopped or whole peeled tomatoes. Whole tomatoes may need crushing or chopping if the recipe calls for smaller pieces. | For a rustic stew, I can use chopped pieces; for a more even pasta sauce, I would consider a finely chopped format. |
| Salt | Read salt per 100g alongside sugars, particularly when the recipe also uses stock, cheese or other salty ingredients. Tesco lists 0.10g per 100g for Napolina Chopped Tomatoes; Mutti lists 0.30g per 100g for its Polpa. | My casserole already contains seasoned ingredients, so I want to know what the tomatoes contribute before adding more seasoning. |
| Leftovers | Follow the exact tin’s directions for transferring, covering and refrigerating unused tomatoes. Tesco lists use within 2 days after opening for its Everyday Value Chopped Tomatoes and the Napolina tin; the checked Cirio listings from Waitrose and Sainsbury’s say 3–4 days. | If one tin will cover two meals, I need to plan the second dish around its opened-pack instructions. |
Mistakes to avoid
-
Assuming a sweet flavour means added sugar
Tomatoes’ naturally occurring sugars are included in the total-sugars figure, so taste or a description on the pack cannot establish what has been added.
Compare “of which sugars” per 100g and read the ingredients list.
-
Comparing different portion sizes
Portion figures can make a direct comparison between tins harder to interpret.
Start with the per-100g figures, then consider how much tomato the recipe uses.
-
Looking only at sugars
Tins with different sugars figures can also have different salt figures, which matters when choosing ingredients for an already seasoned dish.
Compare sugars and salt per 100g on the specific products you are considering.
-
Keeping leftovers by a rule of thumb
Opened-pack directions differ between the checked Tesco, Napolina and Cirio products, so one tin’s period should not be applied to another.
Transfer unused contents where directed, cover and refrigerate them, and follow the use-within period on your tin.
Brand and product references
These figures describe specific labelled products, not every tomato tin made by each brand.
M&S
Its Italian Tomatoes provide a chopped-tomato reference for a per-100g comparison.
- Marks & Spencer lists 2.5g sugars and 0.10g salt per 100g for this product.
- Check the label on the tin you buy; these figures should not be applied to other M&S tomato products.
Tesco
Everyday Value Chopped Tomatoes are an own-label example to compare with other plain chopped tins.
- Tesco lists 2.8g sugars per 100g and names tomatoes, tomato juice and citric acid in the ingredients.
- Check the current product listing and the tin before planning a meal around this particular product.
Napolina
The checked Chopped Tomatoes 400G product is a plain chopped option for sauces and stews.
- Tesco lists 3.6g sugars and 0.10g salt per 100g for that product.
- Use the figures for the exact tin being compared, rather than assuming another pack or variant has the same label.
Mutti
Mutti describes its Polpa as finely chopped and suitable for long cooking when a more even tomato texture is wanted.
- Mutti publishes figures of 2.8g sugars and 0.30g salt per 100g for the Polpa product described.
- The texture description is the manufacturer’s; check the label of the specific variant you choose.
Cirio
The checked listings include both standard chopped tomatoes and a finer Polpa Fine format.
- Sainsbury’s lists 4.3g sugars per 100g for Cirio Chopped Tomatoes; Waitrose lists 3.7g per 100g for Cirio Polpa Fine.
- Those figures belong to different formats, so compare the exact product rather than treating them as interchangeable.

Questions about tinned tomatoes
Does the sugars figure tell me whether sugar was added?
No. The NHS explains that naturally occurring sugars in vegetables are included in the total-sugars figure. Compare “of which sugars” per 100g to assess the labelled amount, and read the ingredients list to check what has been added.
What does “low sugar” mean on a UK food label?
NHS food-label guidance describes 5g total sugars or less per 100g as low for foods. Use that as context for the figure on the exact tin, while checking its ingredients and salt separately.
Should I use chopped or finely chopped tomatoes for a comfort dinner?
Choose standard chopped tomatoes if you want pieces in a chilli, soup or stew; consider finely chopped tomatoes for a more even sauce or bake. Compare the nutrition labels independently, because the size of the tomato pieces does not establish the sugars figure.
How should I keep leftover tinned tomatoes?
Follow the storage and use-within directions on the individual tin, including transferring unused contents where directed, covering them and refrigerating them. Tesco’s checked Everyday Value and Napolina listings say to use leftovers within 2 days; the checked Cirio listings from Waitrose and Sainsbury’s say 3–4 days.
