Shoppers comparing cupboard-meal portions
If you want a low-fat-labelled soup for a quick meal, can size matters. Tesco lists 400g Low Fat Tomato and Low Fat Lentil & Vegetable tins, while Heinz Weight Watchers Tomato is a 295g can.
Who is this for?
Shoppers checking salt as well as fat
A low-fat label does not describe the salt content. Asda lists Heinz Weight Watchers Tomato Soup as low fat, with 1.7g salt in its 295g can.
Vegetarian and allergen-aware shoppers
Check the particular variety rather than relying on its flavour or low-fat label. Asda lists Heinz Weight Watchers Tomato Soup as vegetarian but containing milk; M&S lists its Chunky Vegetable Soup as vegetarian.
What should you check?
Start with the per-100g nutrition panel, then check the figures for the amount you plan to eat and any ingredients you need to avoid.
| Priority | What to check | Your needs |
|---|---|---|
| Fat labelling | Compare total fat per 100g, then look separately at saturates. NHS food-label guidance describes 3g or less of total fat per 100g as low for foods. | I want to compare low-fat options on the same basis, rather than judge them by the front-of-tin wording alone. |
| Salt | Read salt per 100g and per can or serving. Asda lists Heinz Weight Watchers Tomato Soup at 0.6g per 100g and 1.7g per 295g can. | If salt matters to me, the amount in the portion I plan to eat is as important as the low-fat label. |
| Ingredients | Check the exact variety’s ingredient list, highlighted allergens and vegetarian statement. Asda identifies milk in its listing for Heinz Weight Watchers Tomato Soup. | I need a soup that fits my ingredient exclusions, not just a suitable-sounding flavour. |
| Can size | Compare the stated weight with your intended portion. Tesco’s listed low-fat tomato and lentil-and-vegetable tins are 400g; the Heinz Weight Watchers Tomato tin is 295g. | A smaller can may suit one meal, while a larger one may leave soup to store after opening. |
Common buying mistakes
-
Choosing by the low-fat badge alone
Low fat describes total fat, not salt or allergens. Asda lists Heinz Weight Watchers Tomato Soup as low fat, but also reports 1.7g salt per can and milk among its allergens.
Compare fat, saturates and salt on the nutrition panel, then read the ingredients and allergen declaration.
-
Treating different can sizes as the same portion
A 295g Heinz Weight Watchers can and a 400g Tesco tin contain different amounts of soup, so their per-can nutrition figures describe different portions.
Use per-100g figures to compare nutrition, then check what the figures mean for the amount you intend to eat.
-
Assuming a vegetarian soup contains no milk
Asda lists Heinz Weight Watchers Tomato Soup as vegetarian and also identifies milk as an allergen.
If you avoid milk or another ingredient, read the declaration on the exact product before buying.
-
Overlooking instructions for leftovers
Sainsbury’s instructions for Heinz Classic Carrot and Coriander Soup and M&S instructions for Chunky Vegetable Soup both say to refrigerate soup after opening and eat it within two days.
Transfer leftovers to a suitable container and follow the storage instructions on your tin.

Questions about low-fat tinned soup
How can I compare the fat content of tinned soups?
Compare total fat per 100g: NHS food-label guidance describes 3g or less per 100g as low for foods. Check the separate saturates figure and the amount you expect to eat, too.
Does low fat also mean low salt?
No. Fat and salt are separate figures. Asda lists Heinz Weight Watchers Tomato Soup as low fat, with 1.7g salt in its 295g can; check both figures on any soup you are considering.
Does a smaller tin change the nutrition comparison?
Yes: per-can figures describe the contents of that particular can. Compare nutrition per 100g first, then use the stated can or serving figures for the amount you plan to eat.
Is a vegetarian low-fat tomato soup necessarily free from milk?
No. Asda lists Heinz Weight Watchers Tomato Soup as vegetarian but says it contains milk. Read the allergen declaration for the exact variety if you avoid milk.
What should I do with soup left after opening a tin?
Follow the instructions for that product and refrigerate leftovers in a suitable container. Sainsbury’s Heinz Classic Carrot and Coriander Soup listing and the M&S Chunky Vegetable Soup page both say to eat the soup within two days of opening.
