Busy weekday breakfast shoppers
If you plan to heat a tin before work, check its preparation directions and calculate calories for the amount you expect to eat, rather than assuming the labelled portion is a whole tin.
Who is this for?
Shoppers adding bread or toppings
A soup can be below 500 kcal on its own without the complete breakfast being below that figure. Include bread, butter, cheese and other additions in your total.
Shoppers checking salt or allergens
Compare salt for your intended portion and read the allergen declaration on the exact tin. The tomato-soup examples discussed here include products containing milk; Baxters Favourite Cream of Tomato also contains wheat.
What should you check?
Work out your portion and complete breakfast total first, then compare salt, ingredients and preparation details on the tins you are considering.
| Priority | What to check | Your needs |
|---|---|---|
| Breakfast calories | Check kcal per 100g or per portion against the amount you will eat. Add the calories from bread, butter or toppings to the soup total. | I may eat the whole tin, not the portion shown on the label, and want the complete breakfast to remain under 500 kcal. |
| Salt | Compare salt per 100g, then work out the amount in your portion. NHS Inform defines more than 1.5g per 100g as high in salt and 0.3g or less per 100g as low. | If I eat a whole tin, I want to know its salt total, especially when adding other salty foods. |
| Ingredients | Read the current ingredients and allergen declaration. A vegetarian description does not establish that a soup is vegan, milk-free or wheat-free. | Milk or wheat may rule out a particular tin for me, regardless of its calorie figure. |
| Preparation | Check the tin’s heating directions and, if you expect leftovers, its instructions for storing soup after opening. | On a weekday morning, I need preparation that fits the time and equipment I have available. |
Common buying mistakes
-
Treating a labelled portion as the whole tin
A label may give values per 100g or per half can, while you intend to eat all 400g. The portion used changes the calorie and salt totals.
Decide how much soup you will eat, calculate from the label’s stated basis, then include any additions.
-
Comparing calories but not salt
Joybuy lists 1.1g salt per half can for Heinz Cream of Tomato and 2.40g per can for Baxters Favourite Cream of Tomato. Those serving sizes are different, so the figures should not be compared as though they describe the same amount.
Put salt figures on a like-for-like basis, such as per 100g, and check the total for the portion you plan to eat.
-
Assuming vegetarian means milk-free
The tomato-soup examples include products containing milk, and Baxters Favourite Cream of Tomato also contains wheat. A vegetarian description does not answer an allergen or vegan-suitability question.
Read the current ingredients and allergen declaration for the exact product before buying.
-
Using an old product description instead of the tin
Ingredients and nutrition information can change. M&S advises shoppers to read the product label for its Cream of Tomato Soup.
At purchase, confirm the pack size, kcal, salt, allergens, best-before date and preparation directions on the tin you will use.
Brand and retailer references
These examples help identify soups to compare; a brand name alone does not establish a whole-tin calorie or allergen figure.

Heinz Cream of Mushroom Soup 400g
If you expect to eat the whole 400g tin at breakfast, use the current label to calculate its calorie and salt totals and count any bread separately. This soup contains milk and wheat; check the allergen declaration if either matters to you.

For a whole-tin breakfast, check the current 400g tin’s calorie figure and preparation directions, then include any additions in your total. It contains celery, milk and wheat; check the label if you have a dietary requirement.
Frequently asked questions
Does a tin of soup automatically make an under-500-calorie breakfast?
No. Use the calorie figure for the amount you will eat and add any bread, butter, cheese or toppings. Joybuy lists 244 kcal for a full 400g can of Baxters Favourite Cream of Tomato; that figure describes the soup, not the complete breakfast.
Should I compare calories per 100g or per serving?
Use per-100g figures to compare different soups, then calculate from the amount you will actually eat. A manufacturer’s serving may be half a tin when you plan to eat the whole tin.
Which salt figure matters for a whole tin?
Calculate the salt in the whole tin from the label’s stated serving or per-100g figure. For comparison, NHS Inform defines more than 1.5g salt per 100g as high and 0.3g or less per 100g as low; also check how much soup you intend to eat.
How should I store soup left after opening a tin?
Follow the exact pack instructions rather than leaving leftovers in the opened can. The Heinz Cream of Tomato listing says to transfer unused soup to a suitable container, refrigerate it and eat it within two days; check your tin in case its directions differ.
Are creamy tomato soups suitable for milk-free or wheat-free diets?
Do not assume they are. The Heinz Cream of Tomato listing declares milk, while Baxters Favourite Cream of Tomato declares milk and wheat. Read the current ingredients and allergen statement for the exact soup you are buying.
