What to check on the tin
Start with total sugars per 100g for comparable ready-to-heat soups, then check your portion and any ingredients or preparation steps that affect the choice.
| Priority | What to check | Your needs |
| Total sugars |
Compare the total-sugars line per 100g on ready-to-heat tins. Sainsbury's lists 2.6g for Heinz No Added Sugar Cream of Tomato; ASDA Groceries lists 1.8g for its Tomato & Three Bean Soup. A no-added-sugar claim does not mean zero total sugars. |
I want to compare soups on the same amount of food, even if their front-of-pack wording differs. |
| Portion |
Check whether the stated serving is half a can or a whole can, then use the amount you intend to eat. Sainsbury's lists 5.3g sugars per half can of the Heinz soup; ASDA Groceries lists 7.2g per whole can of its bean soup. |
A whole tin might be my supper, so a half-can figure alone would not describe my portion. |
| Soup style |
Read the product name and ingredients. The Heinz option is cream of tomato, while ASDA Groceries describes its Tomato & Three Bean Soup as containing beans and red lentils. |
Would I prefer smooth tomato soup tonight, or a soup with beans and lentils? |
| Preparation |
Check whether the soup is ready to heat or condensed. ASDA Groceries says to add a can of water, or a mixture of milk and water, to Campbell's Condensed Cream of Tomato; its 8.1g sugars per 100g is for the soup as sold. |
If I choose condensed soup, I need to account for the liquid I add before comparing my finished bowl. |
| Other label details |
Check allergens and salt for the portion you will eat, along with the instructions for storing leftovers. The compared recipes include milk, celery or mustard, depending on the product. |
Sugar is not my only consideration; ingredients and the amount left after supper may also affect which tin works for me. |

Questions about choosing and using soup
Does “no added sugar” mean a soup contains no sugar?
No. The NHS explains that naturally occurring sugars are included in the total-sugars figure on food labels. Sainsbury's lists Heinz No Added Sugar Cream of Tomato at 2.6g total sugars per 100g, so check both the claim and the nutrition panel.
Should I compare sugars per 100g or per serving?
Use per 100g to compare similar ready-to-heat soups, then check how much you will eat. Sainsbury's lists 5.3g sugars per half can for Heinz No Added Sugar Cream of Tomato, while ASDA Groceries lists 7.2g for a whole can of its Tomato & Three Bean Soup.
Can I compare condensed soup directly with ready-to-heat soup?
Not on their as-sold per-100g figures alone. ASDA Groceries lists Campbell's Condensed Cream of Tomato at 8.1g sugars per 100g as sold and instructs shoppers to add water, or a mixture of milk and water, before heating. Consider the prepared portion and any milk you add.
Which allergens should I check in these soups?
Read the declaration on the particular tin. ASDA Groceries lists milk in Heinz No Added Sugar Cream of Tomato and milk and mustard in ASDA Just Essentials Tomato Soup; the ingredients differ between recipes.
Can I keep soup left over from supper?
Follow the storage directions for the soup you buy. Check what container to use, whether the leftovers must be refrigerated and how soon the label says to use them.
