Who needs which lunch format?

Desk workers comparing sugar and salt

If the label claim catches your eye, use the nutrition panel to compare total sugars and salt per 100g. Then check the figures for the portion you would bring to work.

People packing lunch for one

A 200g can avoids the need to store part of an opened tin. Larger cans can also work if you can split the contents and follow the pack’s storage instructions.

Shoppers avoiding added sugar

Look for a no-added-sugar claim, but read the total-sugars figure too. The NHS explains that naturally occurring sugars are included in that figure on food labels.

What should you check before choosing?

Start with comparable per-100g figures, then work out what the tin size means for your lunch and any leftovers.

Priority What to check Your needs
Total sugars Compare total sugars per 100g, not just “reduced sugar” or “no added sugar”. M&S lists 1.2g, Heinz No Added Sugar 1.9g and Waitrose Essential Reduced Salt & Sugar 2.0g per 100g, according to their retailer listings. I want to compare recipes on the same basis before deciding how much to eat.
Salt Read salt per 100g and for your planned portion. The Tesco and Sainsbury’s reduced-sugar-and-salt listings each give 0.29g salt per 100g; the Heinz No Added Sugar listing gives 0.4g. A sugar claim alone does not settle my salt comparison.
Added sugar Check the wording of the claim and the ingredients. A percentage reduction compares a product with the maker’s stated standard recipe; no added sugar does not mean zero total sugars, as NHS food-label guidance explains. If I am avoiding added sugar specifically, I need to distinguish that from choosing the lowest total-sugars figure.
Portion and storage Check the tin size, stated servings and heating instructions against the equipment available at work. Waitrose and Tesco instruct shoppers to refrigerate unused contents in a non-metallic container and use them within two days. A smaller can suits me if I cannot deal with leftovers; otherwise, I can plan a second serving.

Common label and portion mistakes

  • Treating “reduced sugar” and “no added sugar” as interchangeable

    Reduced-sugar claims refer to a comparison product. A no-added-sugar product can still contain sugars that appear in the total-sugars figure.

    Read the claim alongside the ingredients and sugars per 100g. The NHS explains that naturally occurring sugars are included in total sugars on food labels.

  • Comparing a whole tin with a stated serving

    A larger tin may be labelled as two servings, so its half-can figures do not describe eating the whole tin.

    Compare products per 100g first, then use the pack’s serving information to check the amount you intend to eat.

  • Checking sugar but not salt

    The listed salt figures differ between the reduced-sugar and no-added-sugar examples, and the amount in a serving depends on its size.

    Read the salt line beside total sugars. The NHS food-label guide describes 0.3g salt or less per 100g as low.

  • Opening a large tin without a leftovers plan

    A two-serving tin needs appropriate storage if lunch uses only part of it.

    Follow the current pack instructions. Tesco and Waitrose tell shoppers to transfer unused beans to a non-metallic container, refrigerate them and use them within two days.

Brand and own-label examples

These product-line examples illustrate different claims, nutrition figures and tin sizes; check the current label for the particular product you choose.

Heinz

Heinz Beanz No Added Sugar is listed in 200g cans, a format to consider when packing one lunch.

  • Waitrose & Partners lists 1.9g total sugars per 100g for this product.
  • The same listing gives 0.80g salt per 200g can. No added sugar does not mean sugar-free.

M&S

M&S No Added Sugar Baked Beans come in a 390g can for a lunch that can be portioned or shared.

  • Marks & Spencer lists 1.2g sugars and 0.43g salt per 100g.
  • Its product information flags the beans as unsuitable for people with milk or egg allergy; check the current pack where allergens matter.

Waitrose Essential

Essential Reduced Salt & Sugar Baked Beans come in a 420g, two-serving can.

  • Waitrose & Partners states 30% less sugar and salt than its regular Essential beans, and lists 2.0g sugars and 0.30g salt per 100g.
  • If you use only part of the can, its instructions call for refrigeration and use within two days.

Sainsbury’s

Sainsbury’s Reduced Sugar & Salt Baked Beans are listed in a 400g, two-serving can.

  • Sainsbury’s states 30% less sugar and salt than its standard baked beans and lists 2.8g sugars and 0.29g salt per 100g.
  • The recipe includes steviol glycosides from stevia, which is worth checking if you avoid sweeteners.

Tesco

Tesco Reduced Sugar & Salt Baked Beans are listed in 220g and 420g formats; check which size you are buying.

  • For the 420g product, Tesco states 30% less sugar and 25% less salt than its standard beans, with 3.0g sugars and 0.29g salt per 100g.
  • The 420g can is labelled as two servings, so plan how to store any unused portion.

Joybuy options for a desk lunch

The Joybuy option here is a Branston reduced-sugar-and-salt multipack. Its 410g tins call for a portioning plan if you want less than a whole tin at lunch.

Branston Reduced Sugar & Salt Baked Beans 4 x 410g

Branston Reduced Sugar & Salt Baked Beans 4 x 410g

For a desk lunch, decide how much of a 410g tin you will use and whether you can store the remainder. The product information lists sugar and steviol glycosides, so do not treat its reduced-sugar claim as a no-added-sugar claim. It instructs shoppers to refrigerate opened contents and use them within two days; check the pack’s heating instructions against the equipment available at work.

Questions about reduced-sugar baked beans

Does “no added sugar” mean baked beans contain no sugar?

No. The NHS explains that naturally occurring sugars are included in the total-sugars figure on food labels. Heinz also states that its No Added Sugar beans contain naturally occurring sugars, so compare the per-100g figure as well as the claim.

How can I compare different tin sizes for lunch?

Compare the per-100g nutrition panels, then check the figures for the amount you expect to eat. The listed Heinz No Added Sugar format uses 200g cans, while the Sainsbury’s, Tesco and Waitrose examples have larger cans labelled as two servings.

Are reduced-sugar baked beans automatically low in salt?

No. Read salt separately and account for your portion size. The NHS food-label guide describes 0.3g salt or less per 100g as low; the retailer examples here list figures on both sides of that threshold.

What should I do with beans left in an opened tin?

Follow the current pack instructions. Tesco and Waitrose say to transfer unused contents to a non-metallic container, refrigerate them and use them within two days.
