People counting calories
If you might eat the whole tin, you need its whole-tin calories rather than a figure for 100 g or half a tin.
Who is this for?
Shoppers planning soup as a meal
If soup will be lunch rather than a starter, consider its ingredients and any protein, vegetables or side dish you intend to add. Count those additions as part of the meal.
People also watching salt
If tinned soup is a frequent choice, compare salt for the portion you will eat as well as calories. The NHS advises adults to have no more than 6 g of salt a day.
What should you check?
Start with the portion you expect to eat, then check what else matters to that meal; an under-500-calorie figure is only one part of the decision.
| Priority | What to check | Your needs |
|---|---|---|
| Portion calories | Check whether kcal is given per 100 g, serving or tin. Use the number of servings you will eat and count toppings and sides separately. | I might eat the whole tin, even when the label defines a smaller serving. |
| Meal ingredients | Look at the ingredient list and the stated protein and fibre amounts for your portion. Decide what, if anything, you will serve alongside the soup. | For lunch, I want to plan the complete meal rather than choose solely by the lowest kcal figure. |
| Salt | Compare grams of salt for the amount you will eat. Tesco Groceries lists 1.7–1.9 g per tin across its Heinz Weight Watchers Tomato, WW Carrot & Lentil and Heinz Weight Watchers Chicken listings; the NHS advises adults to have no more than 6 g a day. | If soup is a regular lunch, I want its salt included when considering the rest of my day. |
| Dietary suitability | Read the current ingredient and highlighted allergen information on the exact variety. Do not use a vegetable name or a low-fat label as a substitute. | I need to know whether this particular recipe meets my ingredient or allergen requirements. |
Common buying mistakes
-
Reading half-tin calories as whole-tin calories
Sainsbury's lists its Be Good To Yourself Spiced Lentil & Tomato Soup at 98 kcal per half-tin. Eating its two-serving tin means 196 kcal before any additions.
Check the stated serving size and calculate the amount you will eat; count bread, toppings and other sides separately.
-
Choosing solely by the lowest kcal figure
A tin's calorie total does not describe the complete meal, particularly if you intend to add other foods.
Decide whether you want a snack, starter or lunch, then check the soup's ingredients and plan any accompaniment within the meal's total.
-
Ignoring salt in a low-calorie soup
Tesco Groceries lists 1.7–1.9 g of salt per tin for three of its low-calorie Heinz and WW soups. The NHS advises adults to have no more than 6 g of salt a day.
Compare salt for the portion you will eat, particularly if soup appears regularly in your meals.
-
Assuming a familiar variety meets dietary requirements
A soup's name or front-of-pack wording does not establish whether its current recipe meets a particular ingredient or allergen requirement.
Read the ingredient and allergen panel on the exact tin before buying it.
Brand and range references
These examples illustrate ranges and label checks; a brand name alone does not establish the calories or suitability of every soup it sells.
Heinz
Its Weight Watchers Tomato and Chicken tins provide two individually labelled examples to compare.
- Tesco Groceries lists 76 kcal per 295 g Tomato tin and 92 kcal per 295 g Chicken tin.
- The same listings give 1.7 g and 1.9 g of salt per tin respectively, so compare more than calories.
Campbell's
Its UK condensed-soup range may be used as a soup or as an ingredient.
- Campbell's UK states that its Cream of Chicken Soup has 284 calories per tin.
- If you prepare a condensed soup with other ingredients, include those in the meal total.
Tesco
Tesco Groceries lists own-label low-fat soups alongside other brands' tinned options.
- Its listed options include Tesco Low Fat Tomato Soup.
- Check the current tin's serving size and nutrition panel before assessing its whole-tin calories.
Sainsbury's
Its Be Good To Yourself Spiced Lentil & Tomato Soup is a pulse-based example with two stated servings per tin.
- Sainsbury's lists 98 kcal and 0.88 g salt per half of the 400 g tin.
- For the full tin, count both servings: 196 kcal and 1.76 g salt.
Asda
The Just Essentials Tomato Soup listing is an own-label option to assess by its current pack.
- Check the tin's calories, servings, salt, ingredients and allergens against your requirements.
M&S
Its tinned-soup range includes products marked Eat Well.
- Use the individual soup's nutrition panel and portion size rather than the range label to assess an under-500-calorie meal.
Joybuy soup options
These Joybuy listings cover several tinned soups and a sweet, dessert-style soup. For an under-500-calorie choice, check the current nutrition label for the portion you will eat; the dessert-style option serves a different purpose from a savoury lunch.

Questions about tinned soup
Does a soup under 500 calories automatically help with weight loss?
No. The NHS explains that weight loss depends on taking in less energy than you use. Count the portion you eat and anything served with it as part of your overall intake, rather than treating one tin's calorie figure as the outcome.
Should I use calories per 100 g, serving or tin?
Use the calories for the amount you will actually eat. If you eat both servings from a two-serving tin, count both; Sainsbury's lists its Be Good To Yourself Spiced Lentil & Tomato Soup at 98 kcal per half-tin, or 196 kcal for the whole tin.
Does salt matter when a soup is low in calories?
Yes. Compare salt for your portion separately from calories. Tesco Groceries lists 1.7–1.9 g per tin for its Heinz Weight Watchers Tomato, WW Carrot & Lentil and Heinz Weight Watchers Chicken soups; the NHS advises adults to have no more than 6 g of salt a day.
Can I assume a vegetable soup is vegan or free from allergens?
No. Check the current ingredient and highlighted allergen panel for the exact variety. A vegetable name does not establish whether a particular recipe meets vegan or allergen requirements.
How should I handle soup left in an opened tin?
Follow the storage and use-by-opening instructions on that soup's pack. Check them before saving a second portion, rather than assuming every product has the same directions.
