Families comparing dinner portions
If several people will share a can, compare kcal per 100g first, then work out how much soup each person will actually have.
Who is this dinner choice for?
The useful comparison depends on who will eat the soup and whether it is the main part of dinner or one part of a larger meal.
Households choosing meat-free soup
Tomato, vegetable and lentil recipes offer different textures. Check the vegetarian statement separately from the ingredients and allergen declaration.
Families serving soup as the main dish
Compare the recipe and labelled protein alongside energy, then account for any bread, cheese or other accompaniment when planning dinner.
What should you check on the label?
Start with the amount going into each bowl, then compare nutrition on the same per-100g basis and check whether the recipe suits everyone at the table.
| Priority | What to check | Your needs |
|---|---|---|
| Energy and portions | Compare kcal per 100g, the can size and the amount to be served. A labelled serving may differ from your bowl. | I want to know what each person will eat, not just the figure for 100g. Tesco Groceries lists its Low Fat Tomato Soup at 31 kcal per 100g and 61 kcal per 200g half-can serving. |
| Salt | Read salt per 100g and for the intended portion; include any salty sides in the meal comparison. | If soup is the centre of dinner, I need to consider its salt as well as its calories. Tesco Groceries lists 0.69g salt for a 200g half-can serving of Low Fat Tomato Soup. |
| Recipe and protein | Compare smooth and chunky recipes, then read protein per 100g without treating it as a measure of how filling a meal will be. | A smooth soup may suit a lighter bowl; for a lentil or chicken-and-vegetable recipe, I would also consider what else is being served. Tesco Groceries lists 2.0g protein per 100g for its Low Fat Lentil & Vegetable Soup, while Marks & Spencer lists 3.5g per 100g for its Chunky Chicken and Vegetable Soup. |
| Dietary suitability | Check the current ingredients, allergen declaration and any vegetarian statement for the particular recipe. | Everyone eating dinner needs a suitable option. A vegetable-based name or vegetarian statement does not answer an allergy question. |
| Storage | Read the can’s instructions for any unused soup and plan how much to open. | If we are saving some for another meal, I need to refrigerate leftovers promptly. GOV.UK advises putting leftovers in the fridge within two hours and eating them within 48 hours or freezing them. |
Common mistakes when choosing soup
-
Reading “low fat” as “lowest calorie”
A low-fat description does not replace the energy and salt figures. Tesco Groceries lists 31 kcal per 100g for Tesco Low Fat Tomato Soup and 47 kcal per 100g for the Heinz Vegetable Soup it sells.
Compare kcal and salt per 100g across cans, then check the figures against the portion you intend to serve.
-
Choosing a dinner solely by its calorie figure
The soup with the lowest energy figure may not be the recipe or portion your family wants for a main meal. Sides change the meal’s overall energy and salt.
Compare smooth, lentil and chunky recipes, read the labelled protein, and decide on accompaniments as part of the same meal.
-
Using a vegetarian label as an allergen check
Meat-free suitability and allergen suitability are different questions; ingredients vary by recipe.
Check the current pack’s ingredient and allergen information for every can being served.
-
Opening more soup than the family will eat
Leftovers need timely storage. GOV.UK advises refrigerating them within two hours and eating them within 48 hours or freezing them.
Serve the amount needed, follow the product’s storage instructions for the remainder and use the more cautious applicable timeframe.
Brand examples to compare
These particular soups illustrate different recipes and label figures; a brand name alone does not establish the nutrition of another product in its range.
Tesco
Tesco’s 400g Low Fat Tomato and Low Fat Lentil & Vegetable soups offer two recipes to compare on a per-100g basis.
- Tesco Groceries lists 31 kcal per 100g for the tomato soup and 44 kcal per 100g for the lentil-and-vegetable soup.
- The “low fat” wording does not replace a check of the serving size, salt and current allergen declaration.
Heinz
Heinz has vegetable soup options with different ways of expressing energy on retailer listings.
- Tesco Groceries lists Heinz Vegetable Soup at 47 kcal and 0.7g salt per 100g; Sainsbury’s lists Heinz Weight Watchers Tomato Soup at 76 kcal per can.
- A per-can figure and a per-100g figure are not like-for-like. Check the pack before comparing the portions you would serve.
M&S
M&S lists both chunky chicken-and-vegetable and cream-of-tomato soups, giving families a choice of recipe styles.
- Marks & Spencer lists 44 kcal and 3.5g protein per 100g for its Chunky Chicken and Vegetable Soup, and 63 kcal per 100g for its Cream of Tomato Soup.
- Choose by the specific recipe’s current label, particularly when dietary restrictions or portion size matter.
Campbell’s
Tesco Groceries lists Campbell’s condensed mushroom and chicken soups. Condensed soup calls for a different serving comparison from a ready-to-heat soup.
- The condensed format may suit a household planning to prepare soup or use it in another dish.
- Check the preparation directions and nutrition for the amount you will serve rather than comparing an undiluted quantity with a ready-to-heat bowl.

Heinz Big Soup Beef & Vegetable 400g

Heinz Big Soup Sausage & Vegetable 400g
Consider this sausage-and-vegetable recipe if a meat-containing soup is wanted. It contains pork sausage and wheat; check the 400g can’s current nutrition and allergen label against the portion and dietary needs at your table.
No image available
Heinz Potato & Leek Soup 400g
A vegetarian potato-and-leek option for a meat-free dinner. It contains milk, so it is unsuitable for anyone with a milk allergy; compare the current pack’s portion, energy and salt figures with the rest of the meal.
Questions about soup for dinner
How can I compare the calories in different tinned soups?
Compare kcal per 100g first, then use the label and your intended bowl size to assess each person’s portion. Tesco Groceries, for example, lists its Low Fat Tomato Soup at 31 kcal per 100g and 61 kcal per 200g half-can serving.
Does “low fat” also mean lower in calories and salt?
No: read energy and salt separately for each soup. Tesco Groceries lists Tesco Low Fat Tomato Soup at 31 kcal per 100g and Heinz Vegetable Soup, also described as low fat, at 47 kcal per 100g; compare their salt figures and the amounts you will serve as well.
Is tinned soup enough on its own for family dinner?
That depends on the portion, recipe and what else is served. If soup is the main dish, compare the labelled protein and planned bowl size, then include any bread, cheese or other sides when assessing the complete meal.
Does a vegetable or vegetarian soup still need an allergen check?
Yes. A vegetarian statement addresses meat-free suitability, not whether the recipe suits someone with an allergy; read the current ingredients and allergen declaration on each can.
Can I keep leftover soup for another meal?
Follow the can’s storage instructions and refrigerate unused soup promptly. GOV.UK advises putting leftovers in the fridge within two hours and eating them within 48 hours or freezing them; where instructions differ, follow the more cautious applicable timeframe.
