Sugar-first sauce comparers
If total sugars are your main concern, compare similar sauces per 100g rather than relying on the wording on the front of the pack. Then check how much sauce you plan to serve.
Who is choosing?
No-added-sugar claim seekers
If you want to avoid sugar added as an ingredient, look for the relevant claim and read the ingredients list. The NHS notes that naturally occurring sugars in vegetables still appear in the total-sugars figure.
Quick Italian-night hosts
If preparation time and a sauce for a shared meal come first, check the cooking directions and stated servings alongside the nutrition panel, ingredients and any dietary requirements.
What matters when buying?
For a pasta-sauce comparison, use the per-100g nutrition panel first, then consider the amount you will serve and how the sauce fits the meal.
| Concern | What to check | Who this matters to |
|---|---|---|
| Total sugars | Compare similar sauces by total sugars per 100g. The NHS classifies 5g or less per 100g as low. | If I am choosing a tomato sauce for pasta, I want comparable figures even when jars and suggested portions differ; about 36% of consumers would put total sugars first. |
| Added sugar | Check the no-added-sugar claim, ingredients and total sugars per 100g. | I may chiefly want to avoid sugar added to the sauce, while accepting that tomatoes contain naturally occurring sugars; roughly 29% of consumers would make avoiding added sugar their primary concern. |
| Preparation and servings | Check the cooking instructions and stated servings, as well as the nutrition panel. | When I am making pasta for a small group with little preparation time, the sauce format and amount matter most; about 21% of consumers would prioritise convenience and sharing. |
| Ingredients and dietary fit | Read the current ingredients and allergen statement; check dietary labels where relevant. | If someone at the table has an ingredient or dietary restriction, a suitable sugar figure is not enough on its own; around 14% of consumers would put dietary compatibility first. |
Checks that are easy to miss
-
Assuming no added sugar means the lowest total sugars
Sugars naturally present in tomatoes and other vegetables still count towards the total-sugars figure, as the NHS explains. Two sauces with different front-of-pack claims can therefore have different per-100g totals.
Read both the claim and the nutrition panel. If total sugars are your priority, compare similar sauces per 100g.
-
Comparing unlike portions
Different jar sizes and suggested servings make per-portion figures harder to compare directly.
Use per 100g for the initial comparison, then check the portion you expect to use for the meal.
-
Treating a quick format as a sugar choice
ASDA Groceries lists 6.5g sugars and 1.1g salt per 100g for its Tomato & Basil Stir-In Sauce. Those figures describe that product, not stir-in sauces as a category.
If speed leads your decision, compare the chosen stir-in sauce with jarred alternatives on per-100g sugars and salt before buying.
-
Using an old product listing as the final label
The ingredients, allergen information and instructions that matter are those for the pack you will serve.
Check the current pack before purchase and again before serving, particularly when an allergy or dietary restriction is involved.

Common questions
Does no added sugar mean a pasta sauce is low in total sugars?
No. The NHS explains that naturally occurring sugars in vegetables are included in the total-sugars figure. Compare similar sauces per 100g; the NHS classifies 5g or less of total sugars per 100g as low.
Should I compare pasta sauces per portion or per 100g?
Start with per 100g to compare sauces on a common basis, then look at the amount you expect to serve. A manufacturer’s suggested portion may differ from yours.
Can a sauce with less sugar still conflict with a dietary requirement?
Yes. Sugar figures do not establish whether a sauce meets an allergy or other dietary requirement. Check the current ingredients and allergen statement for the exact product rather than assuming that every sauce from a brand has the same formulation.
How long can I keep pasta sauce after opening?
Follow the instructions on the individual pack. For example, the Daylesford Organic Tomato and Basil Sauce listed by Marks & Spencer says to refrigerate after opening and use within five days; another sauce may give different instructions.
