What should you compare?
Decide how much soup you expect to eat during the break, then compare labels on the same weight basis before checking whether the tin suits your facilities and dietary requirements.
| Priority | What to check | Your needs |
| Break-time portion |
Check the labelled serving and calories, not just tin size. Tesco Groceries lists 61 kcal per 200 g half-can of Tesco Low Fat Tomato Soup and 102 kcal per half-can of Heinz Cream of Tomato. |
I want a smaller hot meal that fits the time and food I have planned for my shift. |
| Salt |
Compare salt per 100 g and for the portion you will eat. Tesco Groceries lists 0.69 g per 200 g half-can for its Low Fat Tomato Soup; Marks & Spencer lists 0.45 g per 100 g for its Cream of Tomato Soup. |
If soup is a regular cupboard choice, I want to compare tins without mistaking a half-can figure for a per-100 g figure. |
| Chunky ingredients |
Read the ingredients and labelled protein and fibre values. Marks & Spencer lists 3.2 g protein and 2.7 g fibre per 100 g for its chilli-and-bean soup, and 3.5 g protein per 100 g for its chicken-and-vegetable soup. |
A tomato soup may not be the kind of meal I want on this break; I would rather choose a bean-based or meat-based bowl. |
| Dietary suitability |
Read the current ingredients, allergen declaration and any precautionary wording. Heinz Cream of Tomato contains milk; Marks & Spencer states that its vegan chilli-and-bean soup is unsuitable for milk or egg allergy. |
I need the exact tin to meet my dietary requirements, not just a flavour or vegan label that sounds suitable. |
| Preparation and leftovers |
Check the tin’s heating method and whether you have the required equipment. Follow its instructions for transferring, refrigerating and using any soup left after opening. |
There is limited time on my break, and I may want to use the rest of the tin later. |

These product-line examples show why it is worth checking individual labels; a brand name alone does not establish a soup’s nutrition or dietary suitability.

Common questions
Should I choose tomato or chunky soup for a night shift?
Choose by the meal you want during that break: tomato soup can suit a smaller portion, while bean-based or chicken-and-vegetable soup offers a chunkier option. Compare the intended portion, salt, ingredients and allergens on the exact tin.
How do I compare salt between tins?
Start with the per-100 g figures, then check how much salt is in the portion you expect to eat. The NHS advises checking food labels for salt; front-of-pack traffic-light labelling, where present, also identifies whether the labelled amounts of salt, fat, saturated fat and sugars are high, medium or low.
Does a vegan soup suit someone with a milk or egg allergy?
Not necessarily. Marks & Spencer labels its Chunky Mexican-style Chilli and Bean Soup vegan but states that it is unsuitable for people with a milk or egg allergy. Check the current tin’s allergen declaration and precautionary wording.
How should I store soup left after opening a tin?
Follow the instructions for that product rather than assuming one storage period applies to all soups. Tesco Groceries gives a four-day refrigerated limit after transferring its Low Fat Tomato Soup to a covered, non-metallic container; Marks & Spencer gives a two-day refrigerated limit for its Cream of Tomato Soup.
What should I check before heating soup at work?
Check the tin’s preparation directions and make sure you have the required equipment and enough time during your break. If its microwave directions require a separate bowl, use one that meets those directions rather than heating the soup in the tin.
