Parents comparing sugar claims
If the front of the tin says ‘reduced sugar’ or ‘no added sugar’, check the sugars line per 100g before comparing products of different sizes. Check salt and allergens separately.
Who is this choice for?
The useful comparison depends on whether sugars, salt or the practicalities of packing one portion matter most to you.
Parents packing one portion
A smaller tin may make portioning simpler than opening a larger one for a single lunch. Tesco Groceries lists a 220g reduced-sugar-and-salt tin; if you use only part of any tin, follow its storage instructions for the remainder.
Parents comparing sugar and salt together
The figures do not all move in the same direction. Tesco Groceries lists 0.29g salt per 100g for its reduced-sugar tin, compared with 0.43g for the M&S no-added-sugar beans on the Marks & Spencer page; their declared sugars are 3.0g and 1.2g per 100g respectively.
What should you compare?
Start with the nutrition panel on a common per-100g basis, then consider the portion you will pack and the current label on the tin.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars | Compare sugars per 100g, not just ‘reduced sugar’ or ‘no added sugar’. The product pages from Marks & Spencer, Tesco Groceries, Sainsbury’s and Waitrose & Partners declare figures from 1.2g to 3.0g per 100g for the products discussed here. | I want to compare what is in the beans, even when the tins use different sugar claims. |
| Salt | Read salt per 100g alongside sugars. Tesco Groceries and Sainsbury’s each declare 0.29g salt per 100g for their reduced-sugar-and-salt products; Marks & Spencer declares 0.43g per 100g for its no-added-sugar beans. | Lower declared sugars are not my only consideration; I want to see the salt figure too. |
| Portion and storage | Compare tin size with the amount you intend to pack. Check the tin’s instructions for storing any unused beans; Safefood advises keeping packed foods that require cooling as cold as possible in an insulated box or bag. | If I am packing one lunch, I need a workable plan for both the portion and any leftovers. |
| Allergens | Check the current physical pack’s ingredients and allergen information. Marks & Spencer states that its No Added Sugar Baked Beans are not suitable for people with milk or egg allergy. | When buying for a child with an allergy, I cannot assume one baked-bean recipe has the same suitability as another. |
Common buying mistakes
-
Treating ‘reduced sugar’ and ‘no added sugar’ as identical figures
These phrases describe different claims; neither gives the sugars per 100g on its own. Across the product pages from Marks & Spencer, Tesco Groceries, Sainsbury’s and Waitrose & Partners discussed here, declared sugars run from 1.2g to 3.0g per 100g.
Compare the nutrition panels first, then read what each front-of-pack claim refers to.
-
Choosing on sugars without reading salt
The Marks & Spencer no-added-sugar beans declare 1.2g sugars and 0.43g salt per 100g. Tesco Groceries declares 3.0g sugars and 0.29g salt per 100g for its reduced-sugar-and-salt tin.
Read both lines on the same per-100g basis and decide which difference matters for the lunch you are preparing.
-
Opening a large tin without planning for the rest
Using only part of a tin leaves opened beans to handle and store after the lunch portion has been prepared.
Choose a size that fits your planned portions, and follow the current tin’s instructions for transferring and refrigerating leftovers.
-
Assuming no-added-sugar beans have the same allergen suitability
Marks & Spencer states that its No Added Sugar Baked Beans are not suitable for people with milk or egg allergy.
If an allergy is relevant, check the physical pack each time rather than relying on the product category or a previous purchase.

Frequently asked questions
Does ‘no added sugar’ mean baked beans contain no sugar?
No. Tesco Groceries declares 1.9g sugars per 100g for Heinz No Added Sugar Beanz, and Marks & Spencer declares 1.2g per 100g for its No Added Sugar Baked Beans. Read the sugars line rather than treating the claim as a zero-sugar figure.
How can I compare tins of different sizes?
Compare the declared sugars and salt per 100g first, then consider how much you intend to pack. For the named products on the Marks & Spencer, Tesco Groceries, Sainsbury’s and Waitrose & Partners pages, sugars range from 1.2g to 3.0g per 100g and salt from 0.29g to 0.43g per 100g; those ranges do not make every tin equally convenient to portion.
What should I do with beans left in an opened tin?
Follow the current tin’s instructions for transferring, refrigerating and using the unused beans. If one lunch needs only a small portion, plan for the remainder before opening a larger tin.
Do England’s School Food Standards decide what goes in every parent-packed lunch?
The Department for Education’s school food standards guidance for England is directed at schools and caterers; it does not set out a product-specific rule for every parent-packed lunch. Check your child’s school’s packed-lunch policy for its own requirements.
How should prepared beans be carried in a lunchbox?
For packed foods that require cooling, Safefood advises keeping them as cold as possible and using an insulated box or bag. Follow the bean tin’s instructions after opening; do not treat an opened portion as an unopened ambient tin.
