For a plain tomato base during the restrictive low FODMAP step, check the ingredients and serving size separately from the salt figure: a reduced-salt label does not establish FODMAP suitability. Monash FODMAP includes canned tomato in its shopping guidance but advises checking ingredients and consulting its Food Guide for serving information. Compare salt per 100g on the current pack, then consider what else goes into the dish.
If you want a plain tomato base, check both the ingredients and the portion. Monash FODMAP advises checking ingredients and using its Food Guide for serving information; a salt claim answers neither question.
Use the salt figure per 100g to compare tins, then consider salt from the other ingredients and seasoning in your recipe. NHS guidance includes salt already in food and salt added during cooking when discussing total intake.
A plain tin gives you a clearer ingredient list to screen than a garlic-flavoured variant. Monash FODMAP lists garlic and onion among high FODMAP foods in its restrictive-step guidance.
Start with the exact variant and its ingredients, check the serving guidance, then compare salt using the same per-100g measure.
| Priority | What to check | Your needs |
|---|---|---|
| Ingredients | Read the full ingredient list on the exact tin. Check for garlic, onion and other added flavourings; do not use a reduced-salt claim as a FODMAP check. | I want a plain base whose ingredients I can screen before adding it to a meal. Monash FODMAP advises checking canned-tomato ingredients before purchase. |
| Serving size | Check the serving information in the Monash FODMAP Food Guide and consider the other ingredients in the meal. Do not assume that any quantity of a plain tin will suit the restrictive step. | The amount I use matters as well as the ingredients in the tin. |
| Salt | Compare salt per 100g rather than per tin. Product information from Tesco Groceries lists KTC chopped tomatoes at 0.09g per 100g; Marks & Spencer lists its Italian chopped tomatoes at 0.10g, and Ocado lists Mutti Polpa at 0.30g on the same basis. | I want to compare like with like, then account for salt from stock, sauces or seasoning added to the dish. |
| Exact variant | Confirm whether the tin is plain or flavoured, and recheck its current ingredient and nutrition panels. Tesco Groceries lists garlic-flavoured variants alongside plain chopped tomatoes. | A familiar brand name is not enough for me to identify the particular tin I intend to use. |
Salt and FODMAP suitability require different checks. A tin can have a lower salt figure while its flavourings or the portion used still matter during the restrictive step.
Compare salt per 100g, read the ingredients separately and check serving guidance from Monash FODMAP.
Tesco Groceries lists garlic-flavoured chopped tomatoes from Tesco and Napolina alongside other tomato tins. Monash FODMAP lists garlic among high FODMAP foods in its restrictive-step guidance.
Check the full variant name and ingredient panel rather than relying on the brand or front of the tin.
The pack you buy is the relevant reference for ingredients, nutrition and storage instructions.
Use online listings to identify options, then check the current label when purchasing.
NHS guidance counts salt already in food as well as salt added during and after cooking. Other recipe ingredients can therefore change the salt content of the finished dish.
Check the salt figures for ingredients such as stock and sauces when planning the whole recipe.

No. The nutrition panel tells you about salt, while the ingredient list and serving guidance address separate low FODMAP considerations. Monash FODMAP lists garlic and onion among high FODMAP foods in its restrictive-step guidance, so check flavoured tins particularly carefully.
Use the salt figure per 100g on each current label, rather than comparing whole tins of different sizes. In the cited product information, Tesco Groceries lists KTC chopped tomatoes at 0.09g per 100g, Marks & Spencer lists its Italian chopped tomatoes at 0.10g, and Ocado lists Mutti Polpa at 0.30g.
