For lunch, compare sugars and salt per 100g rather than choosing baked beans by a reduced-sugar or no-added-sugar claim alone: Marks & Spencer lists 1.2g sugars and 0.43g salt per 100g for its no-added-sugar tin, while Tesco Groceries lists 3.0g sugars and 0.29g salt per 100g for its reduced-sugar-and-salt tin. A no-added-sugar label does not mean sugar-free; consider the portion you will eat and check the current tin for ingredients and allergy information.
If beans on toast or a jacket potato is a regular quick lunch, compare sugars per 100g across the tins you are considering. The listed figures include 1.2g for M&S No Added Sugar Baked Beans, according to Marks & Spencer, and 3.0g for Tesco Reduced Sugar and Salt Baked Beans, according to Tesco Groceries.
A reduced-sugar claim does not tell you how much salt will be in lunch. Check salt per 100g, then account for the amount of beans you serve and any other salted ingredients in the meal.
A 200g Heinz No Added Sugar single-serve tin, listed by Waitrose & Partners, offers a pre-portioned option. With a larger tin, decide whether lunch will use half the can or more before applying its per-serving nutrition figures.
Start with like-for-like nutrition figures, then check how much of the tin you will use and whether its ingredients suit you.
| Priority | What to check | When it matters |
|---|---|---|
| Sugars | Compare sugars per 100g, not just the front-of-pack claim. Check whether a stated reduction is against that brand’s standard recipe; Tesco Groceries describes its reduced-sugar tin as 30% lower in sugar than Tesco standard baked beans. | I want to compare the sugar figures across different tins, rather than assuming a reduced-sugar claim identifies the lowest figure. |
| Salt | Read salt per 100g and calculate it for the portion you plan to serve. The product listings from Marks & Spencer and Tesco Groceries show why sugar and salt need separate checks: their respective tins declare 0.43g and 0.29g salt per 100g. | If lunch also includes cheese, sauce or other salted ingredients, I need to consider the beans as part of the whole meal. |
| Portion size | Check the tin’s net weight and stated serving size. Compare per-100g figures between recipes, then use the amount you actually serve to understand your lunch portion. | A single 200g tin may be convenient for one lunch; with a larger can, I need to decide how much I will use and what to do with the rest. |
| Ingredients and allergies | Read the current ingredients and allergy statement, including any sweeteners. Marks & Spencer’s listing says its no-added-sugar beans are not suitable for people with milk or egg allergy. | I want to know whether the particular tin fits my ingredient preferences or allergy requirements, regardless of its sugar figure. |
A reduction describes a comparison with another recipe; it does not mean the tin has no added sugar. The Tesco, Sainsbury's and Waitrose Essential reduced-sugar recipes listed here include sugar in their ingredients.
Read the claim and ingredients list, then compare sugars per 100g across the tins you might buy.
A lower sugar figure need not come with a lower salt figure. Marks & Spencer lists 1.2g sugars and 0.43g salt per 100g for its no-added-sugar beans; Tesco Groceries lists 3.0g sugars and 0.29g salt per 100g for its reduced-sugar-and-salt beans.
Compare both figures per 100g and consider the portion alongside the rest of lunch.
Serving information for a large tin may describe half the can. Eating the whole can means eating twice the amount shown for that half-can serving.
Check whether the nutrition panel is per 100g, per serving or both, and use the amount you will actually eat.
Recipes and allergy information can change. Marks & Spencer’s listing specifically warns that its no-added-sugar beans are not suitable for people with milk or egg allergy.
Check the physical tin before eating if an allergen, ingredient or sweetener matters to you.
These product-line figures provide points of comparison; use the current tin when making a final choice.

The 4 x 410g pack suits planning beans across several lunches; check the portion you serve against the tin’s nutrition panel. The listed ingredients include sugar and steviol glycosides, so this is a reduced-sugar choice, not a no-added-sugar one.
No. No-added-sugar baked beans can still contain sugars: Tesco Groceries lists 1.9g sugars per 100g for Heinz No Added Sugar Beanz, for example. Check the nutrition panel if the amount of sugar matters to your choice.
Use per 100g to compare recipes, then use the amount you plan to eat to understand the lunch portion. A serving shown for half a large can is not the figure for the whole can.
Check the salt for your portion and consider other ingredients in the meal. NHS guidance says adults should have no more than 6g of salt a day, including salt already in food and salt added during or after cooking.
Do not assume the same ingredients across reduced-sugar recipes. The listed Asda, Sainsbury's and Heinz products include steviol glycosides, while the Tesco and Waitrose Essential reduced-sugar products include sugar. Read the current ingredient list for the particular tin.
Follow that tin’s storage instructions, including its directions for transferring and refrigerating leftovers and how long to keep them. Check these before choosing a large can for a single lunch.
