Regular sauce and casserole cooks
If you use tomatoes in several meals each week, a plain tin lets you choose the other ingredients yourself. Check its ingredients before using the per-100g sugars figure to compare similar tins.
Who is this for?
Households planning several tins at once
A multipack can fit a week of planned meals. Compare nutrition per 100g rather than per pack, and choose a quantity that matches how often you expect to cook with tomatoes.
Cooks adjusting the flavour of a sauce
Plain chopped tomatoes leave the seasoning to you. If a sauce tastes sharp, Napolina suggests cooking it gently for longer or using onion or carrot rather than adding sugar.
What should you check?
Choose the tomato format your recipes need, read its ingredients, then compare the sugars figures on the same per-100g basis.
| Priority | What to check | Your needs |
|---|---|---|
| Ingredients | Read the full list for sugar or other sweetening ingredients. A plain tin may still show sugars in its nutrition panel: the NHS distinguishes naturally occurring sugars in vegetables from free sugars. | I want a plain tomato base without treating every gram of listed sugar as an added ingredient. |
| Comparable figures | Compare 'of which sugars' per 100g between equivalent plain chopped tins, not between chopped tomatoes and a concentrated or prepared tomato product. Check the current pack as formulations can change. | When choosing between plain chopped tins, I want a like-for-like figure that works even if their pack sizes differ. |
| Tomato format | Check whether the tin contains chopped, finely chopped or whole peeled tomatoes. Read each format's own ingredients and nutrition panel rather than assuming their figures are interchangeable. | A chopped base may fit my planned sauce, while another recipe may call for whole peeled tomatoes. |
| Pack and leftovers | Match the number of tins to planned meals. Read the individual pack's instructions for transferring, refrigerating and using any contents left after opening. | I can use several unopened tins over the week, but I need a plan for anything left from an opened one. |
Common buying mistakes
-
Taking a lower total-sugars figure as proof of less added sugar
The nutrition figure includes sugars naturally present in tomatoes. Two plain tins can have different listed totals without that difference establishing how much sugar, if any, was added.
Look for sugar or sweetening ingredients in the ingredients list first. Use the per-100g total only to compare similar plain products.
-
Comparing chopped tomatoes with a different tomato product
A figure for purée, ketchup or a prepared sauce does not answer the same question as a figure for plain chopped tomatoes intended as a cooking base.
Compare plain chopped tins with one another when that is the format your recipe needs. Assess another format against its own ingredients and label.
-
Choosing a multipack without planning opened tins
Several unopened tins can be used across different meals, but opening one starts that product's refrigerated-use period.
Check the instructions on the chosen tin and plan how to use any leftovers. Joybuy's Napolina Chopped Tomatoes 400g listing, for example, says to refrigerate after opening and consume within two days.
-
Using an online listing in place of the current label
Ingredients, nutrition details and storage instructions may change, which matters when a small difference in listed sugars is driving the choice.
Check the ingredients, per-100g panel and after-opening directions on the pack you buy.
Brand and own-label references
These product-line examples show which label details matter; they do not imply that every variant from a brand has the same ingredients or nutrition.
Napolina
Napolina sells standard chopped tomatoes in single tins and multipacks, alongside flavoured variants.
- Napolina lists 3.6g sugars per 100g for its standard chopped tomatoes. The reviewed Sainsbury's 4 × 400g listing names tomatoes and citric acid as ingredients.
- Check the exact tin: garlic, herb and chilli variants need their own ingredient and nutrition checks.
M&S
M&S Italian Tomatoes 400g is a plain chopped-tomato option for comparing total sugars per 100g.
- Marks & Spencer lists 2.5g sugars per 100g and ingredients including chopped tomatoes, tomato juice and citric acid for the reviewed product.
- Read the current pack before relying on its online food details.
Sainsbury's
Sainsbury's Italian Chopped Tomatoes 4 × 400g is a plain multipack for meals using several tins.
- Sainsbury's lists 3.5g sugars per 100g and names tomatoes and concentrated tomato juice among the ingredients of the reviewed pack.
- The four-tin format does not itself indicate a lower sugars figure; compare per 100g.
Tesco
Tesco own-label chopped tomatoes include a plain 400g value-line tin.
- The reviewed Tesco Everyday Value Chopped Tomatoes listing gives 2.8g sugars per 100g.
- Check current stock and the pack label before making it part of a weekly meal plan.
Mutti
Mutti Polpa is a finely chopped tomato option when that texture suits the recipe.
- Tesco describes the reviewed Mutti Polpa product as finely chopped Italian tomatoes.
- Check the nutrition panel on the exact pack before comparing its sugars figure with plain chopped tins.
Tinned tomatoes on Joybuy
These options include chopped tomatoes and whole peeled tomatoes in multipacks for planned cooking. If your recipe calls for chopped tomatoes, check the format before comparing labels; a whole peeled tin is a different choice, not a like-for-like substitute.

Mutti Finely Chopped Tomatoes 4 × 400g
Four finely chopped tins suit recipes planned across several meals. The listing states tomato and salt as ingredients and 2.8g total sugars per 100g; that figure does not identify added sugar. Check the current pack's storage directions before using leftovers.
Image unavailable
Mutti Peeled Tomatoes 4 × 400g
This four-tin pack is peeled rather than chopped, so choose it when that format works for your recipe. The listing names peeled tomatoes and tomato juice and states 2.9g total sugars per 100g. Compare it with other peeled tomatoes if the sugars figure is your deciding factor.
Image unavailable
Laila Plum Tomatoes 12 × 400g
The 12-tin pack makes sense only if you expect to use that quantity; these are whole peeled plum tomatoes, not chopped. The listing names tomatoes and tomato juice and states 3.5g total sugars per 100g. Its directions say to transfer opened contents to a non-metallic airtight container, refrigerate and consume within two days.
Image unavailable
Napolina Peeled Plum Tomatoes 4 × 400g
Consider this four-pack for meals that call for peeled plum tomatoes rather than a ready-chopped base. The listing names tomatoes and tomato juice and states 3.4g total sugars per 100g, not added sugars. Its after-opening instruction is to cover, refrigerate and use within two days.
Image unavailable
Napolina Chopped Tomatoes 4 × 400g
These four chopped-tomato tins match recipes needing a plain chopped base. The listing names tomatoes and citric acid, with 3.6g total sugars per 100g; no sugar is listed as an ingredient, but the nutrition figure is not a measure of added sugar. Follow the current tin's directions for storing opened contents.
Questions about choosing tinned tomatoes
Does 'of which sugars' mean sugar was added?
No. It reports total sugars, including sugars naturally present in tomatoes. The NHS distinguishes naturally occurring sugars in vegetables from free sugars, so read the ingredients to check for sugar or other sweetening ingredients rather than drawing that conclusion from the nutrition figure alone.
How should I compare tins of different sizes?
Compare the 'of which sugars' figures per 100g for the same type of tomato. The NHS notes that nutrition information is given per 100g or 100ml, providing a consistent basis even when one option is a single tin and another is a multipack.
How long can I keep tomatoes after opening a tin?
Follow the directions on that tin rather than applying one product's time limit to another. For example, Joybuy's Napolina Chopped Tomatoes 400g listing says to refrigerate after opening and consume within two days; check the current pack for its full storage instructions.
Should I choose plain or flavoured chopped tomatoes?
Choose plain chopped tomatoes if you want to decide what seasoning goes into the dish. Napolina's reviewed standard chopped-tomato ingredients list tomatoes and citric acid, but its flavoured variants need separate ingredient and nutrition checks; a flavour name alone cannot tell you their sugar content.
