For a quick desk lunch, compare plain tinned tomatoes by sugars per 100g and check the ingredients rather than assuming that a lower sugars figure means no sugar was added. M&S lists 2.5g sugars per 100g for its Italian Tomatoes, while Mutti lists 2.8g for Polpa; these are figures for those specific products, not their whole ranges. Finely chopped tomatoes suit a more even sauce, while standard chopped tomatoes retain more distinct pieces.
If tomatoes form the base of a quick pasta, bean, soup or egg lunch, comparing sugars per 100g is more useful than comparing figures for different serving sizes. The ingredients list answers a separate question: whether sweetening ingredients have been added.
If your requirement is a plain formulation, read the ingredients rather than looking only for the lowest sugars figure. Tomatoes can still have a listed sugars value when no sugar has been added.
Finely chopped tomatoes are worth considering when you want a more even texture without breaking down larger pieces. Standard chopped tomatoes make more sense when you want the pieces to remain noticeable.
Start with the sugars figure and ingredients, then choose a texture and tin size that fit the time and portions available for lunch.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars and ingredients | Compare similar plain tomatoes per 100g, then read the ingredients for added sweetening ingredients. Diabetes UK recommends per-100g figures for comparing similar foods; UK Department of Health & Social Care guidance distinguishes sugars naturally present in canned vegetables from free sugars. | I want a lower listed sugars figure, but I also want to know whether anything was added to sweeten the tomatoes. |
| Texture | Check whether the tin contains finely chopped tomatoes or larger chopped pieces. Mutti describes Polpa as finely chopped; Napolina describes its chopped tomatoes as chunky. | For a short lunch break, I would rather use a more even tomato base—or keep visible pieces if that is the texture I want. |
| Salt | Compare salt on the same per-100g basis as sugars. Biona lists 0.02g salt per 100g for its Organic Chopped Tomatoes; Mutti lists 0.30g for Polpa, according to their product panels. | Once the ingredients suit me, I want to compare salt too, rather than choosing on the sugars figure alone. |
| Portions and leftovers | Check the tin size and its specific instructions for storing opened contents. Tesco lists a 227g Italian Chopped Tomatoes tin; storage periods differ between products. | A smaller tin may suit one lunch. If I open a larger tin, I need a plan for the remainder and should follow its pack instructions. |
The nutrition panel reports sugars, including those naturally present in tomatoes. It does not tell you by itself whether a sweetening ingredient was added.
Compare plain tins per 100g and read the ingredients. If no added sugar is your requirement, check for that statement on the current pack as well.
Chunky chopped tomatoes leave more noticeable pieces; a finely chopped product is more convenient when you want an even sauce without breaking down larger pieces.
Match the texture to your lunch: consider finely chopped tomatoes for an even base, or standard chopped tomatoes when you want visible pieces.
Brand product panels list different salt figures: Biona Organic Chopped Tomatoes has 0.02g per 100g and Mutti Polpa has 0.30g per 100g.
Read both figures per 100g on the current pack when comparing otherwise suitable tins.
Storage instructions are product-specific. M&S instructs shoppers to transfer opened Chopped Italian Tomatoes to a non-metallic container, refrigerate and eat them within three days; Joybuy’s Napolina Chopped Tomatoes listing gives a two-day period.
Follow the instructions on your pack. If a tin is more than you need for lunch, plan another use for the remainder.
These examples describe specific tomato products, not every tin in each brand’s range.

No. Compare sugars per 100g, then read the ingredients to check for added sweetening ingredients. UK Department of Health & Social Care nutrient-profiling guidance distinguishes free sugars from sugars naturally present in canned vegetables, so a plain tomato tin can list sugars without having added sugar.
Finely chopped tomatoes are a practical choice when you want a more even texture without breaking down larger pieces. Mutti describes its Polpa as suitable for a fast tomato sauce; standard chopped tomatoes such as Napolina’s retain a chunkier texture.
Use the nutrition figures per 100g for a like-for-like comparison, then consider how much of the tin your lunch will use. Diabetes UK notes that manufacturer serving sizes may differ from your own portion.
