Shoppers avoiding added sugar
A no-added-sugar claim addresses added sugar, not all sugars in the soup. Asda lists 2.6g total sugars per 100g for Heinz No Added Sugar Cream of Tomato Soup, so check both the claim and the nutrition panel.
Who needs to check what?
Shoppers comparing sugar and salt
A sugar claim does not settle the salt comparison. Use the per-100g figures on each tin before considering how much soup you expect to eat.
Vegetarian shoppers avoiding milk
Vegetarian does not mean dairy-free. Asda identifies milk as an allergen in Heinz No Added Sugar Cream of Tomato Soup, so check the exact tin’s allergen declaration if milk matters to your choice.
What matters when comparing tins?
Start with the sugar claim that matches your aim, then compare the nutrition panels and check ingredients that could rule out a recipe.
| Priority | What to check | Your needs |
|---|---|---|
| Added sugar | Look for an explicit no-added-sugar claim. Read total sugars per 100g and the ingredients separately; the claim does not mean sugar-free. | I want to avoid added sugar, but I still need to know how much total sugar is in the soup. |
| Salt | Compare salt per 100g on the tins themselves. If a pack says “less salt”, check which product it uses as the comparator. | Keeping an eye on salt matters to me as well as checking the sugar claim. |
| Ingredients and allergens | Read the current ingredients and allergen declaration. Check for milk in creamy soups and for sweeteners if you prefer to avoid them. | A vegetarian label alone will not tell me whether a soup fits my need to avoid milk. |
| Portions and preparation | Compare nutrition per 100g before using portion figures. Check the tin size, heating directions and instructions for leftovers. | I want to know what a bowl made from this tin involves, especially if I will not eat it all at once. |
Common label-reading mistakes
-
Reading “no added sugar” as “sugar-free”
Tomato soup can still contain naturally occurring sugars. Asda lists 2.6g total sugars per 100g for Heinz No Added Sugar Cream of Tomato Soup.
Use the claim to identify the added-sugar choice, then read total sugars per 100g and the ingredients list.
-
Skipping salt because the sugar claim looks suitable
Sugar and salt are separate parts of the label. Action on Salt & Sugar’s February 2026 snapshot found that 23% of the 481 UK ready-to-eat soups it assessed exceeded UK salt-reduction targets.
Compare the salt figures per 100g on the particular tins you are considering.
-
Assuming vegetarian cream of tomato soup is dairy-free
A vegetarian recipe can contain milk; Asda lists milk as an allergen in the Heinz no-added-sugar tomato soup.
If you need to avoid milk, read the allergen declaration and ingredients on the exact tin.
-
Comparing unlike serving figures
A stated portion may differ from the amount you intend to eat. The NHS explains that nutrition information is given per 100g or 100ml and may also be shown per portion.
Compare soups per 100g first, then use the tin size to consider your own serving.
Brand and retailer references
These examples show different ways to check a soup label; a brand or retailer name alone does not establish that a particular tin meets a reduced-sugar requirement.
Heinz
Heinz No Added Sugar Cream of Tomato Soup is a 400g tin with an explicit no-added-sugar claim. Asda lists 2.6g total sugars per 100g.
- The product listing identifies milk as an allergen, making that check clear for this particular recipe.
- No added sugar does not mean no total sugar. The recipe also uses steviol glycosides, which matters if you avoid sweeteners.
M&S
M&S Cream of Tomato Soup offers a conventional 400g tomato-soup label to compare with a no-added-sugar tin.
- Marks & Spencer lists 5.9g sugars per 100g for this recipe.
- Its ingredients include sugar, so this recipe does not fit a choice to avoid added sugar.
Campbell's
Campbell's Condensed Cream of Tomato Soup is a different preparation choice from a ready-to-heat tin: condensed soup is diluted before serving.
- Joybuy Insights describes adding water or milk to condensed tomato soup before heating it.
- If avoiding added sugar is the deciding factor, check the current Campbell's tin’s ingredients and nutrition panel rather than relying on its condensed format.
Tesco
Tesco’s tinned-soup category offers a low-sugar filter and lists Heinz No Added Sugar Cream of Tomato Soup among its results.
- The category can help narrow the products to inspect.
- Check the individual tin’s claim, nutrition and allergens; a category filter does not answer those questions for every result.
Asda
Asda’s listing for Heinz No Added Sugar Cream of Tomato Soup gives product-specific nutrition and allergen information.
- The listing identifies the no-added-sugar claim, total sugars and milk allergen for this tin.
- For a precise salt comparison, use the figure on the physical tin.
Joybuy soup options
These 400g Joybuy soups give you two recipes to consider for a first shop. If avoiding added sugar is essential, check the current pack rather than treating either as a confirmed no-added-sugar choice.

Heinz Big Soup Sausage & Vegetable 400g
This 400g sausage and vegetable soup offers a different recipe to compare. Its listed ingredients include sugar and glucose syrup, so it does not fit a requirement to avoid added sugar; check the current pack for preparation directions.
Questions before you buy
Does “no added sugar” mean tinned soup contains no sugar?
No. A soup can contain naturally occurring sugars: Asda lists 2.6g total sugars per 100g for Heinz No Added Sugar Cream of Tomato Soup. Read the total-sugars figure alongside the front-of-pack claim.
How can I compare the sugar in two tins?
Compare total sugars per 100g, then consider how much soup you expect to eat. The NHS explains that nutrition information is given per 100g or 100ml and may also be shown per portion; check salt separately.
Is Heinz No Added Sugar Cream of Tomato Soup suitable if I avoid milk?
No if you need to avoid milk: Asda’s product listing identifies milk as an allergen. Its vegetarian suitability does not make it dairy-free, so read the declaration on the current tin.
What should I do with soup left after opening a tin?
Follow that tin’s instructions for transferring and refrigerating unused soup, and check how long the product says to keep it after opening.
