Parents making quick school-holiday lunches
A tin of tomatoes can form the base of a pasta sauce, soup, bean dish or casserole. Check the ingredients if avoiding added sugar matters to your lunch plan.
Who is this for?
Shoppers checking for added sugar
Read the ingredients list first. Then use the sugars-per-100g figure to compare total sugars in otherwise similar tins; the two checks answer different questions.
Family cooks comparing pack sizes
Choose a quantity you can use and compare the ingredients and nutrition labels separately. A multipack or a different tomato texture does not, by itself, tell you whether sugar was added.
What should you check?
Start with the ingredients, then choose a texture and pack quantity that fit the lunches you plan to make.
| Priority | What to check | Your needs |
|---|---|---|
| Added sugar | Read the exact tin’s ingredients for sugar or ingredients used for sweetening. Compare sugars per 100g among similar tins if total sugars also matter; that figure includes naturally occurring tomato sugars, as the NHS explains. | I want a tomato base without added sugar, not a tin that claims to contain no sugars at all. |
| Texture | Choose chopped tomatoes for visible pieces or finely chopped pulp for a more uniform base. Whole peeled tomatoes need crushing or blending if the recipe calls for a finer texture. | For a quick pasta sauce, I would rather start with the texture I need than prepare the tomatoes during lunch. |
| Flavourings | Check each flavoured variant’s ingredients rather than relying on its brand or plain counterpart. ASDA Groceries lists sugar in its Chopped Tomatoes with Chilli and Peppers, but not in its plain Chopped Tomatoes. | I might welcome a pre-seasoned tin, but I want to know what was added before using it for lunch. |
| Pack quantity | Check the number and size of tins, then the pack’s directions for storing any leftovers after opening. | A single tin may cover today’s meal; a multipack makes more sense if I have several lunches planned. |
Common label mistakes
-
Reading total sugars as added sugar
Tomatoes contain naturally occurring sugars, which are included in the total-sugars figure on the nutrition label, as the NHS explains. That number alone cannot tell you whether sugar was added.
Check the ingredients for sugar or sweetening ingredients first; use sugars per 100g for a separate, like-for-like comparison.

Assuming a flavoured tin matches the plain version
ASDA Groceries lists sugar in its Chopped Tomatoes with Chilli and Peppers, while its plain Chopped Tomatoes does not list sugar. Variants within one range can differ.
Read the ingredients on the exact flavour and pack you intend to use.
Brand references for tinned tomatoes
These examples show why the exact product label matters more than a brand name alone.
Napolina
Its Chopped Tomatoes with Herbs are a flavoured, chunky option for sauces.
- Napolina describes this variety as chunky in tomato juice and lists 3.5g sugars per 100g.
- Check the ingredients of the particular flavour; do not use its nutrition label as a substitute for the label on a plain tin.
Mutti
Finely Chopped Tomatoes offer a finer pulp for cooks who do not want larger chopped pieces.
- The Mutti Finely Chopped Tomatoes listing at ASDA Groceries gives tomatoes (99.8%) and salt as ingredients.
- Because salt is an ingredient, check its nutrition panel if salt per 100g matters to your comparison.
Tesco
Its Everyday Value Chopped Tomatoes provide a plain chopped-tomato example.
- Tesco Groceries lists tomato, tomato juice and citric acid, with 2.8g sugars per 100g.
- Tesco’s product page showed this item as out of stock; check availability when shopping.
Sainsbury's
Its tinned-tomato category includes own-label and branded products in different formats.
- The Sainsbury's category listing includes chopped tomatoes from its own-label range alongside Mutti and Napolina.
- Check the ingredients, format and nutrition panel of the individual tin rather than treating the category as one recipe.
Asda
Its plain and flavoured chopped tomatoes illustrate the importance of checking variants separately.
- ASDA Groceries lists tomatoes, concentrated tomato juice and citric acid for its plain Chopped Tomatoes, with 3.8g sugars per 100g.
- Its Chilli and Peppers variant lists sugar as an ingredient.
M&S
Its Chopped Italian Tomatoes are a plain chopped variety in tomato juice.
- Marks & Spencer lists Italian chopped tomatoes, tomato juice and citric acid as ingredients.
- Check the current pack’s ingredients and nutrition panel when comparing it with another variety.

Questions about choosing a tin
Does a sugars figure mean sugar was added to tinned tomatoes?
No. The NHS explains that naturally occurring sugars in vegetables appear in the total-sugars figure on food labels. Read the ingredients to check for added sugar or sweetening ingredients, then compare sugars per 100g if you want to compare similar tins.
Does “no added sugar” mean a tin contains no sugars?
No. Tomatoes can contribute naturally occurring sugars even when no sugar is added. Check both the ingredients and the nutrition panel so you do not mistake the total-sugars figure for a list of added ingredients.
Should I use plain or flavoured tomatoes for a quick lunch?
Choose plain tomatoes if you want to control the seasoning and check for added sugar yourself. A flavoured tin may save a seasoning step, but read its exact ingredients: ASDA Groceries lists sugar in its Chilli and Peppers variety, unlike its plain Chopped Tomatoes.
What should I do with tomatoes left after opening a tin?
Follow the storage and use-within directions on that product’s pack. Check them each time rather than assuming the same instructions apply to every brand or variety.
