Choose plain tinned tomatoes when you want a flexible base that lets you decide what else goes into a meal. Compare energy and salt per 100g on the exact tin, then choose chopped, finely chopped or whole tomatoes for the texture your recipe needs. The finished meal and serving size matter more to a weight-management decision than the tomato tin alone.
The useful distinction is between choosing a cooking base and judging the meal made with it.
Plain tinned tomatoes give you a starting point whose energy value you can read per 100g. Check the amounts of oil, cheese, cream, pasta or rice you add, as well as the number of servings the recipe makes; the tin’s figure does not describe the finished dish.
Salt per 100g makes it easier to compare tins of different sizes. If the recipe also contains stock, cheese, cured meat or salty condiments, check those ingredients too rather than treating the tomato base as the whole dish’s salt figure.
Standard chopped tomatoes leave more visible pieces, while finely chopped tomatoes make a more even base. A flavoured tin may save a preparation step, but check its ingredients and nutrition panel separately from the plain version.
Start with the per-100g label and the recipe you intend to cook; choose texture and pack size after that. Front-of-pack traffic-light labelling, where present, can be a quick starting point, but the detailed panel lets you compare tins on the same basis.
| Priority | What to check | Your needs |
|---|---|---|
| Energy and ingredients | Compare kcal per 100g on the exact tin, then read the ingredients to distinguish plain tomatoes from a prepared sauce. Work out how much tomato and how much of each addition will go into a serving. | I want to use tomatoes as a cooking base while keeping track of the oil, cheese, cream and other ingredients in the finished meal. |
| Salt | Compare salt per 100g across similar tins, including each flavoured variant. The NHS defines 0.3g salt or less per 100g as low; that classification applies to the product, not automatically to the recipe made with it. | If I am using stock, cheese or another salty ingredient, I want to see how much salt the tomatoes contribute before seasoning the dish. |
| Texture | Choose standard chopped for distinct pieces or finely chopped for a more even base. Check whether a whole-tomato tin suits a recipe in which you can crush or blend the tomatoes yourself. | For a quick sauce, I may prefer smaller pieces; for a stew, visible tomato pieces may suit the result I have in mind. |
| Pack and storage | Match the number of tins to how often you cook. Read the exact pack’s instructions for storing and using any tomatoes left after opening. | Several unopened tins could be useful for regular cooking, but I also need a plan for the contents of a tin I only partly use. |
The energy figure on plain tomatoes describes those tomatoes, not a sauce or meal containing oil, cheese, cream, pastry or a large serving of starch.
Use the tin’s per-100g figure alongside the quantities of the other ingredients and the number of servings you actually make.
Salt varies by product. ASDA Groceries lists 0.01g salt per 100g for its plain chopped tomatoes and 0.11g per 100g for its garlic version; Mutti lists 0.30g per 100g for Polpa. These are figures for specific products, not their entire ranges.
Compare the salt line on the exact variant you intend to use, on a per-100g basis.
A multipack changes how many unopened tins you have to store, but it does not solve what to do with tomatoes left in an opened tin.
Check the pack size against how often you cook and follow the opened-storage instructions on each tin.
Unused opened tomatoes may need to be discarded if they are not stored and used within the labelled period.
A damaged can is a food-safety concern, regardless of its ingredients or nutrition figures. Reading Borough Council advises against buying damaged cans.
Inspect tins before buying and choose an undamaged one.

Plain tinned tomatoes can be a flexible cooking base, but the tin alone cannot tell you the energy content of the finished meal. The specific plain products listed by ASDA Groceries, Napolina, Tesco Groceries and Marks & Spencer range from 22 to 25 kcal per 100g. Account for the other ingredients and the serving size you use.
Use salt per 100g for a like-for-like comparison, including when tins differ in size. The NHS defines 0.3g salt or less per 100g as low; salty ingredients added during cooking can still change the finished dish.
Choose chopped tomatoes if you want distinct pieces and finely chopped tomatoes if you want a more even sauce base. Whole tomatoes let you crush or blend them yourself. Choose the format for the recipe’s texture rather than assuming one cut changes the weight-management value of the meal.
Follow the instructions on that tin, including its stated period for using leftovers. For example, Marks & Spencer instructs shoppers to transfer leftovers from its Chopped Italian Tomatoes to a non-metallic container, refrigerate them and eat them within three days. Food Standards Scotland also advises checking the label for storage requirements after opening.
No. Reading Borough Council advises against buying damaged cans because damage can be a food-safety concern. Inspect the can before choosing it, rather than relying only on its label or contents description.
