Shoppers planning a cupboard-stored lunch
A tin can fit an under-500-kcal meal plan, but check the protein and salt in the full can before deciding whether it meets your meal requirements.
Who is this choice for?
Vegetarian or vegan shoppers comparing soup formats
Check protein per pack alongside the current ingredients and allergen label. A chilled lentil soup may be worth considering if refrigeration is practical; it is not a cupboard-stored substitute for a tin.
Shoppers choosing soup as a lighter meal
A low calorie figure does not establish how much protein the meal supplies. Sainsbury’s lists 168 kcal but 5.2 g protein for a full 400 g can of its Vegetable Soup.
What should you check?
Decide whether cupboard storage is essential, then compare the nutrition for the portion you will actually eat.
Shelf-stable tinned soup
Choose when: You need an unopened soup that can be kept in a cupboard. Tesco lists Heinz Big Soup Steak & Potato at 12.4 g protein and 204 kcal for the full 400 g can.
Consider: The same can contains 2.4 g salt, and its protein contribution may not match your intended meal amount.
Chilled soup or broth
Choose when: Refrigeration is practical and a different protein contribution matters more than cupboard storage. According to BOL’s product information listed by Sainsbury’s, its 600 g Tomato, Red Pepper & Lentil pot contains 23 g protein; Sainsbury’s lists 20 g for the 500 g Re:Nourish Chicken Bone Broth bottle.
Consider: These are not tinned cupboard products. Check each pack’s storage directions, portion size and salt before treating it as your meal.
| Priority | What to check | Your needs |
|---|---|---|
| Protein | Read grams of protein for the portion you will eat. If the panel is per half-can or per 100 g, use the pack size and serving count to work out the full amount. | I want to know what the soup contributes to my meal, rather than relying on a front-of-pack claim. |
| Calories | Check kcal per serving and the number of servings in the pack. Count any foods you intend to eat alongside the soup when assessing an under-500-kcal meal. | A half-can figure will not describe my lunch if I eat the whole tin. |
| Salt | Compare salt for the whole portion. GOV.UK guidance recommends no more than 6 g of salt a day for adults; Tesco lists 2.4 g in a full can of Heinz Big Soup Steak & Potato. | I need to see how much salt the soup adds to the rest of my day. |
| Suitability | Read the current ingredients and allergen statement. Check whether the pack is a cupboard-stored tin, a condensed soup needing preparation or a chilled product. | If I need a cupboard lunch or must avoid an ingredient, the storage format and exact label matter as much as the nutrition figures. |
Common buying mistakes
-
Reading a half-can panel as a whole lunch
Tesco lists Heinz Big Soup Steak & Potato at 102 kcal and 1.2 g salt per half-can. Eating the full 400 g tin means 204 kcal and 2.4 g salt.
Check the serving count before using any per-serving figure to plan your meal.
-
Using low calories as a stand-in for protein
Sainsbury’s Vegetable Soup provides 168 kcal and 5.2 g protein per full 400 g can. A low calorie total alone does not tell you whether its protein contribution fits your plan.
Compare grams of protein for the portion you intend to eat, then check its calories separately.
-
Overlooking salt in the full portion
Tesco lists 2.4 g salt in a full Heinz Big Soup Steak & Potato can. GOV.UK recommends that adults have no more than 6 g salt a day.
Use the whole-portion salt figure when comparing soups and planning other meals.
-
Buying chilled soup for a cupboard meal
A chilled soup needs different storage from an unopened ambient tin, even when both suit the calories you have planned for lunch.
Check the storage and use-by directions before choosing a chilled pot or bottle for a later meal.
Brand and retailer references
These examples show why a brand name or product range cannot replace the nutrition and storage details of the particular soup you choose.
Heinz
Tesco lists Heinz Big Soup Steak & Potato as a 400 g tinned soup.
- Tesco’s half-can panel works out to 204 kcal and 12.4 g protein for the full tin.
- The full tin also contains 2.4 g salt; check the current pack when choosing a variant.
Campbell’s
Tesco lists Campbell’s condensed Cream of Mushroom and Cream of Chicken soups in its tinned-and-packet range.
- Condensed soup offers a different preparation format from a ready-to-heat tin.
- Check the preparation instructions and nutrition for the amount you will serve before comparing it with a complete tin.
Tesco
Tesco’s soup range includes tins, condensed products and cup soups.
- Its product listings can show nutrition by a stated serving size.
- Formats are not interchangeable: Tesco lists 4.4 g protein per prepared portion for FUEL10K Vegetable Instant Cup Soup, which is not a tinned meal.
Sainsbury’s
Sainsbury’s lists own-label ambient soup alongside chilled branded options.
- Its Vegetable Soup panel works out to 168 kcal for the full 400 g can.
- That can supplies 5.2 g protein, so compare it with your intended protein contribution rather than judging it by calories alone.
Asda
Asda lists own-label tinned soup, including Just Essentials by Asda Tomato Soup.
- Use the current product’s serving count, protein, calories and salt to assess it for this meal; an own-label range name does not establish those figures.
M&S
M&S sells tinned soup as well as fresh soup. Its Chunky Keralan Chicken Soup is a chilled 600 g product, not a cupboard tin.
- Marks & Spencer lists 59 kcal and 2.9 g protein per 100 g for that chilled soup.
- Calculate nutrition for the portion you will eat and check its current allergen and refrigeration directions.

Frequently asked questions
Does a “high protein” label tell me how much protein my meal contains?
No. Read the grams of protein for the amount you will eat and compare that figure with your intended meal amount. A front-of-pack claim does not replace the serving size or nutrition panel.
How do I check whether a whole tin is under 500 kcal?
Check the number of servings and calculate the calories for the portion you plan to eat. Tesco lists Heinz Big Soup Steak & Potato at 102 kcal per half-can, or 204 kcal for the full 400 g tin; count any additions to the soup separately when assessing the whole meal.
Why check salt if the soup is under 500 kcal?
Calories and salt are separate label figures. Tesco lists 2.4 g salt in a full can of Heinz Big Soup Steak & Potato, while GOV.UK recommends that adults have no more than 6 g salt a day. Compare salt for the portion you will actually eat.
Can chilled high-protein soup replace a tin?
It can be an alternative meal choice when you can refrigerate it, but it cannot replace an unopened tin for cupboard storage. Check the chilled product’s use-by and opened-pack directions as well as its whole-portion nutrition.
What if I need to avoid an allergen?
Read the ingredients and allergen statement on the current pack for the exact soup you intend to eat. Do not assume that another flavour, product format or earlier description has the same ingredients.
