Students and families planning a heated lunch
A cupboard-stored tin can be an option when there is somewhere suitable to heat the soup. Check the instructions for the exact product and work out the calories for the portion being served.
Who is this for?
People counting the soup within a meal
If you expect to eat a whole 400g tin, check whether its nutrition figures are given per half tin. For two equal labelled servings, double the per-serving energy before counting any sides.
Shoppers with dietary or salt considerations
Check the exact tin's ingredients, allergen declaration and salt for the portion being eaten. A calorie figure cannot answer those questions.
What should you check?
Start with the portion you intend to serve, then check whether the recipe and preparation instructions fit the person and lunch setting.
| Priority | What to check | Your needs |
|---|---|---|
| Portion calories | Read the labelled serving count and energy figure. Double a half-tin value only if you will eat both servings; count bread, spreads and other additions separately. | I want to know whether my actual portion of soup stays below 500 kcal, rather than judging a whole tin by its half-tin label. |
| Salt | Calculate salt for the portion eaten as well as calories. ASDA Groceries lists 1.2g per half tin for Heinz Chicken Noodle 400g and 1.1g for Heinz Cream of Tomato 400g: that is 2.4g and 2.2g respectively for a whole tin. | If soup is a regular lunch, I want to compare the salt in a full tin with what else I plan to eat. The NHS notes that ready-made soups can be salty. |
| Ingredients | Read the current ingredients and allergen declaration for the exact recipe. Check any vegetarian statement on that product, rather than applying it to a flavour or brand as a whole. | I need a soup that fits the eater's dietary requirements; a tomato, vegetable or broth name alone does not settle that. |
| Heating and leftovers | Match the pack's heating directions to the facilities available. If serving part of a tin, follow its opened-product storage directions for the remainder. | There needs to be a workable way to heat lunch where it will be eaten, and a plan for any soup left in the tin. |
Common mistakes
-
Reading half-tin calories as whole-tin calories
The 400g Heinz and Sainsbury's examples described by ASDA Groceries and Sainsbury's give energy per half tin. Eating both labelled servings doubles the soup's stated energy.
Calculate the portion you will eat, then count accompaniments separately if the 500-kcal limit applies to the complete lunch.
-
Assuming fewer calories means less salt
ASDA Groceries lists 64 kcal and 1.2g salt per half tin for Heinz Chicken Noodle 400g. A whole tin therefore provides 128 kcal and 2.4g salt.
Compare both figures for your planned portion instead of using calories as a substitute for the salt label.
-
Relying on the flavour name for dietary suitability
Soup recipes differ in their ingredients, even when their names sound similar. A calorie calculation does not identify allergens or establish whether a product is vegetarian.
Read the ingredient list, allergen declaration and any dietary statement on the exact tin you are buying.
-
Counting the soup as the entire lunch
A tin's nutrition panel describes the soup, not bread, drinks or other food served with it.
If your target applies to the whole lunch, calculate those additions as well and plan the meal around the eater's requirements.
Brand and retailer references
Use these ranges to narrow down recipes, then make the calorie and dietary checks on a specific tin.
Heinz
The 400g examples listed by ASDA Groceries include chicken noodle, Scotch broth, carrot and coriander, and cream of tomato.
- Their listed half-tin energy figures allow a whole-tin calculation for those exact products.
- Ingredients and salt differ by recipe; do not apply one tin's label to another.
Tesco
Tesco Groceries lists own-label soup alongside branded, cup and packet formats.
- The range offers different formats to consider for the planned lunch.
- Check the nutrition panel of the particular tin and portion before applying a 500-kcal limit.
Sainsbury's
Sainsbury's lists a 400g Cream of Tomato Soup with two half-tin servings.
- Its listed 114 kcal per half tin equals 228 kcal for the whole tin.
- Its listed 0.89g salt per half tin equals 1.78g for the whole tin; check its ingredients for dietary suitability.
Asda
ASDA Groceries provides individual listings for the Heinz soups used in the portion examples here.

Questions about choosing soup
Does under 500 kcal refer to one serving or the whole tin?
Apply the limit to the amount you will eat. For example, ASDA Groceries lists Heinz Chicken Noodle 400g at 64 kcal per half tin, making the whole tin 128 kcal; food and drinks served with it need their own calculation if the limit covers the complete lunch.
Does a soup below 500 kcal also have less salt?
Not necessarily. ASDA Groceries lists 1.2g salt per half tin for Heinz Chicken Noodle 400g, or 2.4g for the whole tin, despite its 128-kcal whole-tin calculation. Check salt for the portion you intend to eat.
Can the flavour name tell me whether a soup suits a dietary requirement?
No. Check the exact tin's current ingredients, allergen declaration and any vegetarian statement; a flavour name or another recipe from the same brand is not a substitute for that label.
What if there is nowhere to heat soup at school or college?
Check the product's preparation directions and the facilities available before choosing it for that lunch. If you serve only part of a tin, follow its directions for storing the remainder.
