Who these choices suit

Shoppers comparing sugars

If you want a convenient soup lunch with less sugar, compare the total-sugars line rather than relying on a no-added-sugar or low-sugar description alone. Check both the per-100g figure and the amount you intend to eat.

Vegetarian and vegan soup buyers

A vegetable-based flavour does not establish whether a particular recipe is vegan or suitable for your allergies. Check the dietary declaration, ingredients and allergen statement on the exact soup.

Shoppers comparing sugars and salt

If both figures matter to your lunch choice, read them side by side. A per-serving value may describe less than the whole tin, so check the serving size before using it to judge your portion.

What to check on the label

Start with comparable per-100g figures, then use the serving and ingredient information to decide whether the soup fits the lunch you have in mind.

Priority What to check Your needs
Sugar wording Read the exact claim and the total sugars per 100g. No added sugar and sugar-free do not mean the same thing: Sainsbury's lists 2.6g sugars per 100g for Heinz No Added Sugar Cream of Tomato Soup. If I want to avoid added sugar, the claim matters to me; if I want to compare the sugars I will consume, I also need the nutrition figure.
Sugars, salt and portion Compare sugars and salt on the same per-100g basis, then check the labelled serving against the amount you plan to eat. The NHS notes that a manufacturer's portion may differ from yours. A tin might be my whole lunch, even if its serving information covers only part of it. I want to consider salt alongside sugars rather than treating one figure as the whole answer.
Dietary suitability Check the exact product's vegetarian or vegan declaration, ingredients and allergen statement. Recheck the label on the tin you receive. I may want a vegetable soup, but I still need to know whether that particular recipe meets my dietary requirements.

Common buying mistakes

  • Treating no added sugar as sugar-free

    A no-added-sugar soup can still contain total sugars. Sainsbury's lists 2.6g per 100g for Heinz No Added Sugar Cream of Tomato Soup.

    Read the claim alongside the “of which sugars” figure when comparing tins.

  • Choosing by sugars without looking at salt

    Tesco labels Heinz French Onion Soup low sugar and lists 1.9g sugars per 100g, but also lists 0.5g salt per 100g. The sugar description does not describe its salt content.

    Compare both figures per 100g, then check the nutrition for the portion you expect to eat.

  • Using a category filter as an ingredient check

    A retailer filter helps narrow a search, but it cannot tell you whether every individual soup meets your dietary or allergen requirements.

    Open the exact product listing and read its ingredients, allergen statement and dietary declaration before choosing.

  • Relying only on an earlier online listing

    Ingredients and product information can change, which matters particularly when an allergy or strict dietary requirement determines your choice.

    Check the label on the tin you receive before eating it.

Relevant brand and retailer references

These examples illustrate different labels and product types; a statement about one soup does not apply to every soup from the same brand or retailer.

Heinz

The two Heinz soups here show why claim wording and total sugars need separate checks.

  • Sainsbury's lists Heinz No Added Sugar Cream of Tomato Soup at 2.6g sugars per 100g.
  • Tesco lists Heinz French Onion Soup at 1.9g sugars and 0.5g salt per 100g; its ingredients include sugar despite its low-sugar description.

M&S Eat Well

The listed vegetable soups offer product-specific nutrition figures and dietary declarations to compare.

  • M&S lists Chunky Vegetable Soup as vegetarian, with 2.1g sugars and 0.50g salt per 100g.
  • M&S labels its Minestrone vegan and vegetarian but states that it is not suitable for people with milk or egg allergy. Check the exact product's allergen information.

Sainsbury's

Its tinned-soup category includes own-label and branded products and offers a low-sugar filter.

  • The filter can help narrow a search for soups to compare.
  • Open each product to assess its actual sugars, salt, ingredients and allergens; the filter is not a complete suitability check.

Tesco

Its tinned-and-packet-soup category and individual product listings provide options to examine.

  • The Heinz French Onion Soup listing gives per-100g sugars and salt figures as well as ingredients.
  • Use the details for the exact soup rather than treating the broader category as a nutrition comparison.

Questions about choosing tinned soup

Does no added sugar mean a soup is sugar-free?

No. A no-added-sugar soup can still contain total sugars. Sainsbury's lists 2.6g sugars per 100g for Heinz No Added Sugar Cream of Tomato Soup, so check the nutrition panel as well as the claim.

Should I compare soup per tin, per serving or per 100g?

Use per-100g figures to compare soups, then check the labelled serving against the amount you will eat. The NHS notes that a manufacturer's idea of a portion may differ from yours.

Is a low-sugar soup also low in salt?

Not necessarily. Tesco labels Heinz French Onion Soup low sugar but lists 0.5g salt per 100g. Read the salt line separately and consider your intended portion.

Can I assume a vegetable soup is vegan or suitable for my allergies?

No. M&S labels its Minestrone vegan and vegetarian while stating that it is not suitable for people with milk or egg allergy. Check the ingredients and allergen statement for the exact tin you intend to use.
