Who is choosing a single tin?

Single-tin lunch shoppers

If one tin is your planned lunch, compare the nutrition per 100g with the amount you will actually eat. A declared serving may be smaller than the whole tin.

Shoppers looking for pulses or vegetables

Look for lentils, beans or vegetables in the ingredients, then compare fibre, protein and salt on the exact tin. The NHS identifies pulses as a source of fibre and protein; the finished soup still needs its own label check.

Shoppers checking ingredients closely

If salt, sugars or particular allergens affect your choice, compare the current packs rather than flavour names alone. For example, Campbell’s lists wheat and milk in its condensed cream of chicken soup, and milk and celery in its condensed cream of tomato soup.

What should you compare?

Start with the same per-100g basis, then check preparation instructions and the amount you expect to eat. The NHS explains both the per-100g label basis and why a stated portion may differ from your own.

PriorityWhat to checkYour needs
SaltCompare salt per 100g, then check the declared portion and your full lunch amount. The NHS classifies more than 1.5g per 100g as high and 0.3g or less as low.I want to compare similar soups without assuming that a vegetable or tomato name tells me their salt content.
Fibre and proteinLook at the ingredients and the stated fibre and protein values. The NHS identifies beans, peas and lentils as sources of both, but the finished recipe needs checking.A bean or lentil soup appeals to me, but I want to know what the particular tin contributes to lunch.
Portion and preparationCheck the tin’s weight, servings, preparation instructions and whether nutrition is stated for the prepared soup. Compare condensed and ready-to-heat products on the same basis.If I plan to eat the whole tin, I need to account for more than a smaller declared serving.
Sugars and saturated fatCompare both values per 100g between the specific recipes you are considering, then check the amount you will eat.For a tomato or cream-style soup, I would rather compare the labels than judge it by flavour alone.
Ingredients and allergensRead the current pack’s ingredient and allergen information. Campbell’s condensed cream of tomato lists milk and celery; its cream of chicken lists wheat and milk.Where an ingredient affects what I can eat, a retailer listing or a vegetarian description is not enough for my final check.

What can make soup labels misleading?

  • Assuming similar flavours have similar salt levels

    Action on Salt’s 2026 analysis of 481 UK chilled and ambient soups reported variation across products, with 23% exceeding the Government’s voluntary maximum salt target. A flavour name cannot tell you where a particular tin falls.

    Compare salt per 100g on the tins you are considering, then check the amount you will eat.

  • Comparing condensed and ready-to-heat tins by weight alone

    Campbell’s gives nutrition for its condensed soups as consumed. Tin weight alone does not describe the prepared portion.

    Follow the preparation instructions and compare nutrition on the same basis before assessing your lunch portion.

  • Expecting one tin to answer every lunch question

    The NHS Eatwell Guide considers balance across a day or week, rather than requiring every individual meal to contain the same combination of foods.

    Check the soup’s fibre and protein values and consider what else, if anything, you plan to eat with it.

  • Using an online listing as the final allergen check

    Ingredients can change, and a flavour name may not reveal an allergen. Campbell’s condensed tomato soup, for example, lists milk and celery.

    For an allergy or dietary restriction, read the label on the tin you buy and follow its current instructions.

Brand and retailer references

Heinz

Tesco’s soup category lists Heinz tins in 300g and 400g formats, including Big Soup products.

  • The listed formats offer different tin sizes and recipes to compare.
  • A nutrition result for one Heinz soup does not establish the values for another; compare the exact labels.

Campbell’s

Campbell’s condensed soups can be prepared as soup or used in cooking, so preparation matters when comparing them with ready-to-heat tins.

  • Campbell’s publishes as-consumed nutrition for its condensed cream of tomato and cream of chicken soups.
  • Its cream of tomato lists 0.91g salt and 8.1g sugars per 100g as consumed; cream of chicken lists 0.86g salt per 100g as consumed and contains wheat and milk.

Tesco

Tesco’s soup category lists own-label and branded products, including standard tins, condensed soups and other formats.

  • The category provides different recipes and pack formats to compare in one shop.
  • Check that a product is a single tin, then use its own nutrition and allergen information rather than the category or retailer name.

M&S

M&S lists 400g tinned soups including vegetable, lentil, bean and tomato recipes.

  • Its Cream of Tomato Soup listing gives per-100g nutrition, including 0.45g salt and 5.9g sugars.
  • The figures for that tomato soup do not describe the other recipes; M&S advises checking the physical label because product information may change.

Questions about single-tin soup

Should I compare soup per 100g or per tin?

Use both for different purposes: compare products per 100g, then work out what your planned portion means. The NHS notes that nutrition labels use a per-100g basis and that a manufacturer’s stated portion may not match the amount you eat.

Is lentil or bean soup automatically the right lunch choice?

No. The NHS identifies pulses such as lentils and beans as sources of fibre and protein, but that does not establish the nutrition of a finished soup. Check its salt, sugars, fibre, protein, ingredients and the portion you plan to eat.

Does “vegetarian” or “Eat Well” settle an allergen question?

No. Neither description replaces the ingredient and allergen information on the particular tin. Read the current pack if you need to avoid an ingredient; Campbell’s condensed cream of tomato, for example, lists milk and celery.

What should I do with soup left after opening a tin?

Follow that product’s storage directions. M&S instructs shoppers to transfer its opened Cream of Tomato Soup to an airtight container, refrigerate it and eat it within 2 days; do not assume the same instructions apply to every soup.
