Choose tinned soup by the calories in the amount you will actually eat: a half-can figure is not the total for a full can. Tesco Groceries and ASDA Groceries label examples put five 400g soups at 126–194 kcal per whole can, but their calculated whole-can salt figures range from 1.56g to 2.6g. For a night-shift break, compare salt and ingredients too, and choose a portion you can heat and store according to its label.
The useful portion is the one you can realistically eat during your break, whether that is half a can or the whole 400g.
If you want a warm snack or light meal overnight, consider its portion size as well as its calorie figure. The British Nutrition Foundation advises shift workers to avoid large, heavy meals that may cause drowsiness; the British Dietetic Association also discusses breaks with lighter meals or snacks during the night.
If you may finish a 400g can, calculate calories for all 400g rather than comparing a half-can label figure with your limit. Check the serving basis again if you add anything to the soup or prepare it from a condensed product.
Flavour and calorie count do not tell you the salt in your portion or whether the ingredients meet your dietary requirements. Read the exact can’s nutrition, ingredient and allergen information before taking it to work.
Start with the amount you expect to eat, then compare soups on that same portion basis. Condensed soup needs a separate look because its nutrition may be stated for a prepared portion.
| Priority | What to check | Your needs |
|---|---|---|
| Calories for your portion | Find the kcal figure and its serving size. For a 400g can labelled per half can, double the figure if you will eat it all; include any additions when assessing your meal. | I might eat the whole can during one break, so I want that amount—not just the labelled half—to stay below 500 kcal. |
| Soup format | Check whether the nutrition applies to soup straight from the can or to a prepared portion. Campbell’s Soup UK states 142 kcal per 147.5g prepared portion for Cream of Chicken condensed soup and 133 kcal for Cream of Mushroom. | A prepared portion could suit my break, but I need to work out how many portions I will make and eat. |
| Salt | Compare salt for the same amount you plan to eat. Tesco Groceries lists 1.2g salt per half can for Heinz Minestrone and 1.3g for Heinz Chicken Broth: a full can gives 2.4g and 2.6g respectively. | Even if the whole can meets my calorie limit, I want to know its full-can salt figure before choosing it. |
| Ingredients and allergens | Read the exact product’s ingredient and allergen statements. If vegetarian suitability matters, look for a statement on that product rather than judging by its flavour name. | My shift meal needs to fit my dietary requirements, and a vegetable-sounding name is not enough to establish that. |
| Heating and storage | Read the can’s preparation and opened-can storage instructions. Check that you will have the equipment and container needed for the portion you plan to take. | If I cannot heat or store a partly used can as directed during my shift, a different portion plan would be more practical. |
A 400g soup labelled per half can gives nutrition for 200g, not necessarily for everything you will eat on your break.
Double the per-half-can calories and salt if you intend to finish it. For condensed soup, use the stated prepared-portion basis and the number of portions you will eat.
Tesco Groceries lists Heinz Chicken Broth at 68 kcal and 1.3g salt per half can. Eating the full 400g can doubles both figures, so its calorie count alone cannot answer a salt question.
Use any traffic-light label for an initial comparison, then check the nutrition table for the salt in your actual portion.
Products with similar names can have different ingredients and allergen statements. A vegetarian statement also answers a different question from an allergen declaration.
Check both on the exact can you are buying, particularly if a specific ingredient affects your choice.
Saving part of a can for another break makes the product’s opened-can instructions relevant to your shift.
Check its heating and storage directions before packing it, and make sure your workplace arrangements allow you to follow them.
These examples show why it is worth comparing exact products rather than relying on a brand name or a ‘low fat’ description.
Heinz has several 400g soup varieties with per-half-can nutrition figures listed by Tesco Groceries.
Campbell’s condensed soups require attention to preparation and portion size when compared with ready-to-heat 400g cans.
Tesco own-label tinned soup provides another product range to compare with branded cans, including a Low Fat Tomato Soup 400G listing.
These 400g tinned soups offer different flavours and meal styles for a night-shift break. Decide how much you intend to eat, then use the current label to check calories, salt, ingredients and preparation for that amount.

A mushroom soup to consider if you want a 400g can for a warm break. If you plan to eat the whole can rather than part of it, check the whole-can calories and salt; check the exact label for milk and wheat if either affects your diet.

This bean soup is an option if that flavour suits your shift meal. Work from the 400g can size if you expect to eat it all, or measure the portion you take; check the exact label for celery and for opened-can storage directions.

The spicy parsnip-and-carrot variety gives you a different flavour to consider for a warm break. Check the can’s heating and storage instructions before planning to take it to work, and read its allergen statement if celery, milk or wheat affects your choice.

Consider this broth if you want a more substantial style of soup and that suits your overnight break. Compare the label for the portion you will eat; check its ingredients for barley and wheat if gluten affects your diet.

This steak-and-potato variety is worth considering if you prefer a heartier soup to a lighter broth during your break. Use the 400g can size when checking a whole-can meal against your calorie limit, and follow the pack’s serving and preparation directions.
It means the amount of soup you will actually eat, including any additions to your meal. Tesco Groceries lists Heinz Minestrone at 63 kcal per half can, which is 126 kcal if you eat both halves of its 400g can; check the serving basis on any other product before calculating.
Yes: calories and salt need separate checks. Tesco Groceries lists 1.2g salt per half can for Heinz Minestrone and Chicken Noodle, or 2.4g if either full can is eaten; it lists 1.3g per half can for Chicken Broth, or 2.6g for the full can.
Follow the directions on the exact can, including any instructions for heating and storing unused soup. If you intend to eat only part of it, check that you can bring an appropriate container and follow its opened-can storage directions at work.
Use one as a starting point when it appears, not as a substitute for the serving information. GOV.UK describes traffic-light labels as helpful for comparing calories, fat, sugar and salt; the nutrition table lets you work out the figures for the portion you intend to eat.
