Who this is for

Shoppers avoiding added sugar

If a no-added-sugar claim matters to you, read it alongside the total-sugars figure. As the NHS explains, sugars naturally present in vegetables are included in total sugars on food labels.

Households planning several portions

A weekly shop calls for enough sauce for the meals you have planned. Tesco and Sainsbury's each list a 500g no-added-sugar tomato sauce as four portions, while Sainsbury's lists a 350g Loyd Grossman tomato-and-basil sauce as serving two to three.

Shoppers checking ingredients and storage

A sugar claim does not establish whether a sauce meets your allergen or dietary requirements. Check the exact jar for those details, salt and saturated fat, as well as its instructions for use after opening.

What to check when buying

Start with the sugar claim and the total-sugars line, then check whether the jar covers your planned meals and meets your other label requirements.

Concern What to check Who this matters to
Added sugar and total sugars Read the ingredients and compare total sugars per 100g across similar tomato sauces. A no-added-sugar claim does not mean zero total sugars. If I want to avoid added sugar in routine pasta meals, I still need to know what the nutrition panel counts. About 36% of consumers put avoiding added sugar first.
Portions for planned meals Compare jar size with stated servings and the amount your household uses. Tesco and Sainsbury's list the checked 500g tomato sauces as four portions. When one jar needs to cover a family meal, the stated serving count matters more to me than jar size alone. Having enough portions is the primary need for about 29% of consumers.
Salt and saturated fat Compare both figures per 100g and for the amount you expect to use, particularly when considering a cheese-based sauce. I may want a creamy sauce, but I do not want the sugar claim to stand in for the rest of the nutrition panel. About 21% of consumers chiefly need to compare salt and saturated fat.
Ingredients and opened-jar storage Check allergen and dietary declarations on the exact jar, then read its refrigeration and use-after-opening instructions. If I am splitting a jar across meals or avoiding particular ingredients, suitability and storage decide whether I can use it as planned. These are the primary concerns for about 14% of consumers.

Buying pitfalls

  • Reading “no added sugar” as “sugar-free”

    Tomato and vegetable sugars can still appear in total sugars. The NHS distinguishes naturally occurring sugars in vegetables from free sugars while noting that both appear in the label's total-sugars figure.

    Check the ingredients for added sweetening ingredients and compare total sugars per 100g between similar sauces.

  • Letting the sugar claim stand in for the whole nutrition panel

    Sainsbury's lists 3.8g saturates per 100g for the checked Heinz mascarpone sauce. A no-added-sugar claim does not tell you its salt or saturated-fat content.

    Read the salt and saturates lines separately, using the same per-100g basis when comparing jars.

  • Assuming jar size tells you the portion count

    The checked 500g Tesco and Sainsbury's tomato sauces are each listed as four portions; Sainsbury's lists the checked 350g Loyd Grossman sauce as serving two to three.

    Check stated servings against the amount of sauce your household uses for each planned meal.

    A smaller jar may mean opening another one to cover a family meal.

  • Assuming no-added-sugar sauces have the same ingredients or storage instructions

    The checked Tesco tomato sauce is listed as vegan, while the checked Heinz cheese-based sauce contains milk and egg. Instructions for an opened jar also vary by product.

    Read the exact jar's allergen and dietary information, then check how long it can be kept after opening.

Common questions

Does “no added sugar” mean a pasta sauce is sugar-free?

No. Tomatoes and vegetables can contribute sugars to the total-sugars figure even when a sauce is labelled no added sugar. The NHS explains that naturally occurring sugars in vegetables are included in total sugars on food labels.

What matters most when buying sauce for several meals?

Check stated servings against how much sauce your household uses, then compare nutrition per 100g and the ingredients. Tesco and Sainsbury's each list a checked 500g no-added-sugar tomato sauce as four portions; a smaller jar may suit a different meal plan.

Are no-added-sugar sauces also lower in salt or saturated fat?

The sugar claim does not establish either figure. Sainsbury's lists 3.8g saturates per 100g for the checked Heinz mascarpone sauce, so compare salt and saturates on the specific jars you are considering.

How long can I keep an opened jar?

Follow the storage instructions on the jar you buy. Instructions differ between sauces: the product information for the Homepride carbonara pasta bake says to refrigerate and use within three days of opening, while the Heinz tomato, mascarpone and Grana Padano sauce says within two days.
