Families planning weekday portions
If soup is lunch, a light dinner or a starter, compare the amount each person will eat with the serving on the label. Include bread, spreads and toppings when considering the whole meal.
Who is this for?
Shoppers planning a more substantial lunch
If soup will be the main part of lunch, compare the protein and fibre shown for the actual portion. Vegetable, bean, lentil and chicken recipes can differ considerably, so the recipe name alone is not enough.
Households with different dietary requirements
Check the current can for ingredients, allergens and dietary suitability before serving. Ingredients such as milk, wheat, egg, celery and meat matter to different members of the household.
What should you check?
Start with comparable per-100g figures, then use the serving information and the amount you intend to serve to assess the meal.
| Priority | What to check | Your needs |
|---|---|---|
| Portions and energy | Compare kcal per 100g, then the kcal in the portion actually served. Check the can size and stated number of servings rather than treating one can as one family portion. | I want to know how much soup each person will have and account for any bread, spreads or toppings alongside it. |
| Salt | Compare salt in g per 100g and in the portion served. An NHS traffic-light label can help screen products, but check the figures and portion size as well. | For a soup we might serve regularly, I want to compare salt without assuming that a vegetable or low-fat label tells me the answer. |
| Meal composition | Read the ingredient list and compare protein and fibre per 100g or serving. Check what vegetables, pulses or other foods will accompany the soup. | If soup is the main part of lunch, I want to see what it contributes and plan the rest of the meal accordingly. |
| Dietary suitability | Read the current ingredients and highlighted allergens. Check any vegetarian or vegan statement on the exact product rather than judging by its flavour name. | Someone at our table needs the soup and its accompaniments to meet their dietary requirements. |
Common buying mistakes
-
Choosing on a low-fat or low-calorie claim alone
That claim does not describe the whole meal or tell you the protein, fibre and salt in the portion you serve.
Compare the nutrition panel per 100g and for the intended portion, then include any bread, spreads, cheese or toppings in your meal planning.
-
Assuming a familiar soup style means less salt
Action on Salt & Sugar found salt levels ranging from 0.1g to 1.6g per 100g across 481 ready-to-eat soups sold by major UK retailers in its February 2026 snapshot. The range does not tell you the level in a particular can.
Compare the salt figures on the products you are considering, both per 100g and for the amount each person will eat.
-
Planning family portions from can size alone
Sainsbury's lists two servings for its 400g Tomato & Spicy Lentil Soup, and its listing of Heinz Chicken Noodle Soup also states two servings for a 400g can. Neither can should be assumed to provide a whole family main meal.
Decide whether soup is a starter or part of a main meal, then check the serving count and plan any other food accordingly.
-
Relying on an old ingredients list
An earlier purchase is not a substitute for the label on the can being served, particularly when someone has an allergy or other dietary restriction.
Read the current ingredients, highlighted allergens and suitability information before serving.
Brand and retailer ranges to compare
These examples show why it is worth comparing individual cans; a brand or retailer name does not establish the nutrition of every soup in its range.
Heinz
The Heinz Chicken Noodle Soup 400g listing provides a specific chicken-and-noodle example for label comparison.
- Sainsbury's lists 32kcal and 1.3g protein per 100g for this soup.
- The same listing gives 0.6g salt per 100g and identifies wheat, egg and celery or celeriac ingredients; check the exact can.
Tesco
Tesco's own-label tinned-soup listings include tomato and lentil-and-vegetable options.
- Its low-fat category listing includes Tesco Low Fat Tomato Soup 400g and Tesco Low Fat Lentil & Vegetable Soup 400g.
- A category filter cannot replace a comparison of the exact product's nutrition panel and serving size.
Sainsbury's
Its Tomato & Spicy Lentil Soup, Be Good To Yourself 400g offers a specific pulse-based example.
- Sainsbury's lists 49kcal, 2.8g protein and 1.0g fibre per 100g for this product.
- It lists 0.44g salt per 100g and two servings per can, so compare salt for the portion actually served.
M&S
M&S lists distinct chicken-and-vegetable and bean-based soups with different nutrition figures.
- Marks & Spencer lists 3.5g protein per 100g for Chunky Chicken and Vegetable Soup, and 2.7g fibre per 100g for Chunky Mexican-style Chilli and Bean Soup.
- Check each recipe's ingredients and allergens: the chicken-and-vegetable product lists celery and gluten-containing barley.

Frequently asked questions
Can tinned soup be part of a family weight-management meal?
Yes, depending on the portion and the rest of the meal. NHS guidance emphasises an eating pattern that works in everyday life; compare the soup's kcal and salt per 100g and for the amount served, then account for bread, spreads and toppings too.
What counts as high salt on a soup label?
NHS food-label guidance classifies more than 1.5g salt per 100g as high and 0.3g or less per 100g as low for foods. Compare the per-100g figure between soups, then check how much salt is in the portion each person will eat.
Will one 400g can serve a family?
Do not assume it will. Sainsbury's lists two servings per can for both its 400g Tomato & Spicy Lentil Soup and Heinz Chicken Noodle Soup 400g. Check the particular can and decide whether soup is a starter or one part of a larger meal.
Should I check soup allergens each time I buy it?
Yes, if someone eating it has an allergy: read the current can before serving. NHS food-label guidance says allergens must be highlighted in the ingredients list of pre-packed foods; an earlier purchase is not a substitute for the current label.
How should I store leftover tinned soup?
Follow the storage instructions on the exact can. For example, Marks & Spencer instructs shoppers to transfer leftover Chunky Chicken and Vegetable Soup to an airtight container, refrigerate it and eat it within two days; check your chosen soup for its own directions.
