Budget-conscious meal planners
If you use tomatoes in sauces, soups or stews, consider how much of a tin you will use alongside its nutrition label. A pack that suits your cooking routine may help you avoid leaving opened tomatoes unused.
Who is this for?
Home cooks counting carbohydrate
Diabetes UK advises checking total carbohydrate on the back-of-pack label. Per-100g information lets you calculate the amount in the tomatoes used for a recipe, particularly if carbohydrate counting is part of your insulin routine.
Regular batch-cookers
Multipacks may suit frequent cooking if you have room for the unopened tins, can use them before their best-before dates and can follow each product’s instructions once a tin is opened.
What should you check?
Start with the nutrition label for the exact tin, then choose a texture and pack size that suit the dishes you make.
| Priority | What to check | Your needs |
|---|---|---|
| Total carbohydrate | Read total carbohydrate per 100g and calculate it for the weight used in your recipe. Do not substitute the sugars figure or a traffic-light colour. | I need to account for the tomatoes in my portion, rather than assume a stated serving size matches my meal. Diabetes UK advises using the back-of-pack carbohydrate figure. |
| Salt and ingredients | Compare salt per 100g on the exact products. Check ingredients when switching between plain and flavoured tins. | If I am changing brands or choosing a flavoured tin, I want to know what else is in it. Napolina declares 0.10g salt per 100g for its plain chopped tomatoes; Mutti declares 0.30g per 100g for Polpa. |
| Tomato texture | Distinguish chopped tomatoes from finely chopped pulp. Texture alone does not establish a nutritional difference. | For a sauce with visible tomato pieces, I may prefer the chunky texture Napolina describes; for a finer pulp, I may consider Mutti Polpa. Those cooking descriptions come from the manufacturers. |
| Pack size | Check the number and weight of tins, available cupboard space and best-before dates. | A multipack makes sense for my household only if I expect to use the tins and can store them appropriately. |
| Opened tins | Read the exact product’s transfer, refrigeration and consume-within instructions; do not reuse another product’s storage period. | When a recipe uses part of a tin, I need to know how to store the remainder and when to use it. |
Common buying mistakes
-
Using a sugars traffic light as the whole carbohydrate check
Diabetes UK notes that front-of-pack labels do not show total carbohydrate, which matters when calculating the amount in a meal.
Read total carbohydrate per 100g on the back of the tin and calculate it for the amount used. If you follow a carbohydrate-counting plan, use the approach agreed with your diabetes healthcare team.
-
Assuming every tomato variant has the same ingredients
Plain and flavoured tins can differ, so a brand name alone does not tell you what is in a particular variant.
Compare the ingredients and per-100g nutrition on the exact tins, especially when swapping plain chopped tomatoes for a flavoured version.
-
Applying one tin’s storage period to another
Joybuy’s Napolina Chopped Tomatoes 400g page specifies two days after opening, while its Mutti Finely Chopped Tomatoes 4 x 400g page specifies five days.
Follow the transfer, refrigeration and consume-within directions on the exact pack you open.

Tesco
Tesco’s chopped-tomato category includes own-label plain tins, Grower's Harvest, branded products and multipacks.
- Several listed pack formats give regular cooks options to compare.
- Check the ingredients and nutrition of each individual product rather than treating a category listing as its food label.

- Napolina declares 3.6g carbohydrate, 3.6g sugars and 0.10g salt per 100g for its plain Chopped Tomatoes.

- Mutti declares 3.9g carbohydrate, 2.8g sugars and 0.30g salt per 100g for Polpa.

Frequently asked questions
Is any tin of tomatoes automatically suitable for someone with diabetes?
No single tin suits every person or meal plan. Diabetes UK advises checking total carbohydrate, not just sugars or a front-of-pack colour; calculate it for the quantity you will use.
Should I choose the tin with the lowest sugars figure?
Not on that figure alone. Compare total carbohydrate, salt and ingredients per 100g, then consider your portion and the rest of the meal. Napolina declares 3.6g carbohydrate and 0.10g salt per 100g for plain Chopped Tomatoes; Mutti declares 3.9g carbohydrate and 0.30g salt per 100g for Polpa.
What if a tin has no traffic-light label?
Use its nutrition table to compare like-for-like products per 100g. Diabetes UK advises checking the back-of-pack total carbohydrate figure because front-of-pack traffic lights do not show it.
How long can I keep tomatoes after opening a tin?
Follow the directions on the exact product. Joybuy’s Napolina Chopped Tomatoes 400g page says to transfer the contents to a covered non-metallic container, refrigerate and use within two days; its Mutti Finely Chopped Tomatoes 4 x 400g page specifies refrigeration and use within five days after opening.
