Total-sugar comparers
Shoppers comparing ready sauces for a regular pasta lunch who want to use the sugars-per-100g figure rather than rely on a claim on the front of the jar.
Who is this for?
No-added-sugar convenience shoppers
People looking for a ready-made sauce labelled no added sugar who will also check its total sugars and salt.
Dietary-detail checkers
Shoppers who need to check ingredients, allergens, dietary statements or after-opening storage alongside the nutrition panel.
What matters when choosing?
For a ready sauce, compare sugars and salt on the same per-100g basis, then check the exact pack against your ingredients and storage needs.
| Concern | What to check | Who this matters to |
|---|---|---|
| Total sugars | Compare the ‘of which sugars’ value per 100g; use your intended portion to assess the amount in your lunch. | If I use different amounts of sauce at lunch, I want a consistent way to compare total sugars; about 46% of consumers put that comparison first. |
| No-added-sugar claim | Check the claim on the exact variant, then read its total sugars and salt per 100g. | When lunch needs to be quick, I want a ready sauce labelled no added sugar without overlooking the rest of its nutrition panel; about 36% of consumers prioritise that combination. |
| Dietary details and storage | Read the current ingredients and allergen statement, plus the instructions for keeping sauce after opening. | For lunches planned around dietary requirements or leftovers, I need the sauce to fit those practical needs; about 18% of consumers put these checks first. |
Buying pitfalls
-
Assuming ‘no added sugar’ means the lowest total sugars
The phrases answer different questions. Tesco No Added Sugar Bolognese lists 4.5g sugars per 100g, while Marks & Spencer lists 4.0g per 100g for Classic Tomato Everything Sauce, whose ingredients include sugar.
Compare ‘of which sugars’ per 100g first; use a no-added-sugar claim as a separate consideration.
-
Checking sugars but not salt
The NHS low-salt threshold for foods is 0.3g or less per 100g. Tesco lists 0.64g salt per 100g for its No Added Sugar Bolognese, and Marks & Spencer lists 0.85g for Classic Tomato Everything Sauce.
Read both lines of the nutrition panel when comparing sauces for regular lunches.
-
Assuming tomato sauces meet the same dietary needs
Tesco lists its No Added Sugar Bolognese as suitable for vegans. Marks & Spencer lists celery in Classic Tomato Everything Sauce and states that it is not suitable for people with milk or egg allergy.
Check the ingredients, allergen statement and dietary wording on the exact pack you intend to use.
-
Choosing a jar size without checking storage
After-opening instructions vary: Tesco says to refrigerate its No Added Sugar Bolognese and use it within 14 days, while the Joybuy listing for Mutti Tomato & Basil No Added Sugar says five days.
Choose a quantity you expect to use within the exact product’s stated storage window, and follow its refrigeration instructions.
Sauce left unused beyond that window may need to be discarded.
Brands to consider
Tesco
Its No Added Sugar Bolognese is a ready tomato, onion and herb sauce for shoppers comparing labelled products.
- Tesco lists the 500g product as suitable for vegans, with 4.5g sugars per 100g.
- It lists 0.64g salt per 100g; check the current pack before buying.
M&S
Classic Tomato Everything Sauce offers a useful label comparison when total sugars matter more than a no-added-sugar claim.
- Marks & Spencer lists 4.0g sugars per 100g for this sauce.
- Its ingredients include sugar; it also lists 0.85g salt per 100g, celery and milk and egg allergy exclusions.
Dolmio
Dolmio describes a no-added-sugar range for shoppers seeking a ready pasta sauce.
- The brand states that its no-added-sugar sauce is made without added sugar.
- Compare total sugars, salt and allergens on the exact variant rather than extending the range description to every Dolmio sauce.
Napolina
Napolina presents passata as a smooth, sieved-tomato base for making pasta sauce rather than a finished seasoned sauce.
- Starting with passata lets you choose the other ingredients in the finished recipe.
- It takes preparation, and the finished sauce’s nutrition depends on what you add.
