Who is this choice for?

Parents comparing salt for younger children

A reduced-salt claim is only a starting point when choosing a lunch portion. The NHS gives maximum daily salt amounts of 3g for children aged 4–6 and 5g for those aged 7–10; the beans are one part of the day's food.

Families checking sugar and salt separately

A no-added-sugar recipe may suit a different shopping priority from the tin with the lowest listed salt. Compare both claims, the salt figure per 100g and the current ingredient list.

Parents planning portions from a full-size tin

Per-100g figures make recipes easier to compare, while a stated half-can figure helps with lunch planning. The amount a child will actually eat may differ from either serving size.

What should you compare?

Start with salt per 100g to compare recipes, then consider the portion, ingredients and practicalities of the school lunch.

Priority What to check Your needs
Salt Compare the current label's salt per 100g, then the amount in the portion. Sainsbury's lists 0.29g per 100g and 0.59g per half can; Waitrose Essential lists 0.30g and 0.63g respectively. I want to know how much salt is in the beans I actually pack, rather than choose by the reduced-salt wording alone. The NHS daily maximum also varies by a child's age.
Sugar and ingredients Check whether the tin says reduced sugar or no added sugar, and read its ingredient list. Compare salt separately: Asda lists 0.34g per 100g, while Waitrose & Partners lists 0.40g for Heinz No Added Sugar Beanz. If no added sugar matters in our household, I still want to check the recipe's salt figure and ingredients.
Portions and leftovers Check the tin size, stated serving and instructions for storing unused beans. Asda lists 0.70g salt per half can of its 410g reduced-salt recipe. A smaller lunch portion may leave beans for another meal, so I need a storage plan that follows the instructions on that tin.
Lunch arrangements Read the current allergen information and your school's packed-lunch policy. Decide how the beans will be carried and served before choosing a portion. Will the child eat the beans as packed, and does the school permit the container and serving arrangement I have in mind?

What is easy to overlook?

  • Choosing by a reduced-salt claim alone

    The listed salt still differs between recipes: Sainsbury's gives 0.29g per 100g, Waitrose Essential 0.30g and Asda 0.34g. Those figures do not tell you how much is in a smaller or larger lunch portion.

    Compare per 100g first, then use the current tin's figures to assess the amount you plan to pack.

  • Treating no added sugar as a salt comparison

    Waitrose & Partners lists Heinz No Added Sugar Beanz at 0.40g salt per 100g, while M&S Food lists 0.43g for its No Added Sugar Baked Beans. Both figures exceed those listed for the Sainsbury's, Waitrose Essential and Asda reduced-salt tins discussed here.

    Check the sugar formulation and the salt value as separate parts of the decision.

  • Forgetting the rest of the lunch

    The NHS gives different daily salt maximums for children aged 4–6 and 7–10. Bread, fillings, snacks and other meals also contribute to the day's total.

    Choose a bean portion in the context of the whole lunch, rather than treating the stated half can as a required serving.

  • Assuming every tin has the same allergy and storage information

    The M&S Food listing says its No Added Sugar Baked Beans are not suitable for people with a milk allergy. Instructions for unused beans need checking on the particular tin.

    Read the physical pack when buying for someone with an allergy, and follow that pack's directions for storing leftovers.

Relevant brand and retailer options

These references concern the named baked-bean recipes, not every product sold by each brand or retailer.

Sainsbury's

Its Reduced Sugar & Salt Baked Beans are a reference point when comparing the listed salt in full-size tins.

  • Sainsbury's lists 0.29g salt per 100g and 0.59g per half can for the 400g tin.
  • Check the ingredients and the portion you intend to serve; a half can is not necessarily a child's lunch portion.

Waitrose Essential

Its Reduced Salt & Sugar Baked Beans offer another per-100g and half-can comparison.

  • Waitrose & Partners lists 0.30g salt per 100g and 0.63g per half can.
  • The stated half-can serving may be larger than the portion planned for lunch.

Asda

Its Reduced Salt & No Added Sugar Baked Beans combine two distinct recipe claims.

  • Asda lists 0.34g salt per 100g and 0.70g per half can of the 410g tin.
  • No added sugar does not mean this recipe has the lowest listed salt among these tins; check the current ingredients too.

Heinz

Heinz No Added Sugar Beanz is a branded option for shoppers comparing sugar formulation as well as salt.

  • Heinz states that this recipe has 25% less salt than standard Heinz Beanz.
  • Waitrose & Partners lists 0.40g salt per 100g for the product; compare that figure with other tins rather than treating Heinz's reduction claim as a cross-brand ranking.

M&S

M&S No Added Sugar Baked Beans provide a further recipe to assess on its own label.

  • M&S Food lists 0.43g salt per 100g.
  • The M&S Food listing says the product is not suitable for people with a milk allergy; check the current pack before serving it to anyone with an allergy.

Questions about packing beans for school

Which of these tins lists the least salt per 100g?

Sainsbury's lists 0.29g salt per 100g for its Reduced Sugar & Salt Baked Beans, compared with 0.30g for Waitrose Essential Reduced Salt & Sugar Baked Beans. That is a comparison of the named product listings, not a judgement about every baked-bean tin or the right portion for every child.

Does reduced salt tell me how much salt is in lunch?

No. The claim describes a reduction against another recipe, while the salt in lunch depends on the tin's listed value and the amount packed. Read the current per-100g figure and work from the portion the child is likely to eat.

What do the half-can salt figures mean for a child?

Sainsbury's lists 0.59g salt per half can, Waitrose Essential 0.63g and Asda 0.70g for the recipes discussed here. The NHS gives daily salt maximums of 3g for ages 4–6 and 5g for ages 7–10, so consider the child's actual bean portion alongside the rest of the day's food.

Can I keep beans left over from an opened tin?

Follow the storage and use-by instructions on that exact tin. Plan where to put unused beans and when to use them before opening a full-size can for a smaller lunch portion.

What should I check before packing beans for school?

Check the current pack's ingredients and allergen information, the portion and how the beans will be carried and served. Check the school's own packed-lunch policy as well; the M&S Food listing specifically says its No Added Sugar Baked Beans are not suitable for people with a milk allergy.
