Regular beans-on-toast shoppers
If baked beans are a frequent quick dinner, the salt figure per 100g helps you compare tins without relying on “reduced salt” wording alone.
Who is comparing these beans?
Shoppers checking sugar as well as salt
If both claims matter to you, compare the nutrition panel and ingredients. “No added sugar” does not tell you which tin has the lower salt figure.
People cooking for one
A smaller tin may fit a single meal with fewer leftovers. Compare its serving information with a larger tin before deciding which size suits you.
What should you check on the tin?
Start with salt per 100g for a like-for-like comparison, then check the portion and pack you expect to use.
| Priority | What to check | Your needs |
|---|---|---|
| Salt per 100g | Compare the stated salt figures, not just reduced-salt claims. Nidirect’s Northern Ireland guidance describes 0.3g or less per 100g as low. | I want to compare tins of different sizes on the same basis before choosing one for dinner. |
| Portion salt | Check how much salt is in the amount you will eat. Tesco Groceries lists 0.60g per half of its 420g can; Sainsbury’s lists 0.59g per half of its 400g can. | For half a tin on toast, the salt in that serving matters as well as the per-100g figure. |
| Sugar and sweeteners | Read the nutrition panel and ingredient list separately. A no-added-sugar claim does not establish the product’s salt level or whether it contains sweeteners. | If I am comparing sugar claims too, I want to know what is in the recipe rather than treating one front-of-pack phrase as the whole answer. |
| Tin size | Match a single-serve tin, larger tin or multipack to the number of portions you expect to use. Follow the chosen can’s instructions for leftovers. | A smaller tin may suit dinner for one; for shared or repeat meals, I may use the contents of larger tins. |
Common buying mistakes
-
Assuming “reduced salt” means low in salt
A reduction is relative to another recipe. Sainsbury’s lists 0.5g salt per 100g for Branston Reduced Sugar & Salt beans, above the 0.3g-per-100g level described as low in nidirect’s Northern Ireland guidance.
Compare the per-100g figure first, then check the salt in the portion you plan to serve.
-
Using “no added sugar” as a salt comparison
Waitrose & Partners lists 0.4g salt per 100g for Heinz No Added Sugar beans. Its sugar claim does not make it the lower-salt choice compared with the Sainsbury’s product listing 0.29g per 100g.
Decide which claims matter for this meal, and check salt, sugar and ingredients as separate pieces of information.
-
Relying on an older online ingredient list
Ingredients and nutrition information can change, which matters particularly when an allergy or intolerance affects what you can serve.
Read the label on the exact can before preparing it; Marks & Spencer also advises shoppers to check the product label.

Frequently asked questions
Does “reduced salt” mean baked beans are low in salt?
No. A reduced-salt claim compares a recipe with another version; it does not give its salt figure per 100g. Sainsbury’s lists 0.5g per 100g for Branston Reduced Sugar & Salt beans, while nidirect’s Northern Ireland guidance describes 0.3g or less per 100g as low. Check the figure on the tin you buy.
Should I compare salt per serving or per 100g?
Use salt per 100g to compare different tins, then use the serving information for the amount you plan to eat. Tesco Groceries lists 0.60g for half of its 420g Reduced Sugar and Salt tin; a different portion calls for a different calculation.
Can reduced-salt baked beans contain sweeteners?
Yes, some recipes can contain sweeteners. If you want to avoid a particular ingredient, read the current tin’s ingredient list rather than relying on its reduced-salt or sugar claim.
What should I do with beans left in an opened tin?
Follow the instructions on the exact product. Waitrose & Partners says to transfer leftover Essential Reduced Salt & Sugar beans to a non-metallic container, cover, refrigerate and use within two days.
Is an online ingredient list enough for an allergy decision?
Check the label on the physical can before serving. Product information can change, and Marks & Spencer advises shoppers to read the product label rather than relying solely on an online listing.
