Who is this for?

Salt-conscious lunch planners

If pasta is a regular lunch, comparing sauce labels per 100g and for the portion you serve helps you account for its salt contribution. The NHS advises adults to have no more than 6g of salt a day from all foods and added salt combined.

Time-pressed lunch shoppers

A stir-in sauce can reduce preparation at lunchtime. Check its stated serving size against the amount you will use: Dolmio lists 1g of salt per 75g portion for its Tomato and Basil Stir In Sauce.

Tomato-sauce shoppers

If tomato flavour or vegetable ingredients shape your choice, compare salt separately. The figures published for the cited M&S and Dolmio sauces differ, so their names and ingredients alone cannot settle the salt comparison.

What matters when choosing?

For a lower-salt pasta lunch, compare sauces on the same per-100g basis before considering your serving size, preparation time and any dietary requirements.

Concern What to check Who this matters to
Salt in the meal Compare salt in g per 100g, then work out the amount in the sauce portion you will use. For regular pasta lunches, I want to keep track of the salt my sauce adds to the meal; about 36% of consumers put salt comparison first.
Preparation time Check how the sauce is prepared and whether its stated serving matches your lunch. If lunch must be ready quickly, I need a format that fits the time available without overlooking the portion; about 29% of consumers prioritise speed.
Tomato flavour and ingredients Compare the ingredients and salt figures of sauces in the style you want. I may favour a tomato-based sauce for its flavour but still want to choose between recipes; roughly 21% of consumers make that combination their primary concern.
Dietary details and storage Read the current allergen and dietary information, plus instructions for storing an opened jar. When I split a jar across lunches or need to avoid an allergen, the label must fit those requirements; around 14% of consumers put this information first.

Common buying mistakes

  • Reading 'low fat' or 'quick' as 'lower salt'

    Those descriptions refer to different features. Dolmio lists 0.67g salt per 100g for its Low Fat Bolognese Sauce and 1.3g per 100g for its Tomato and Basil Stir In Sauce.

    Use the salt line for the exact variety, comparing per 100g and then the portion you intend to eat.

  • Judging a sauce by jar size alone

    Pack sizes and stated portions differ, so jar size does not tell you how much salt will be in your lunch.

    Compare per 100g first and follow the after-opening instructions if you plan to use a jar for several meals.

    An opened jar may go to waste if you cannot use it within the period stated on its label.

  • Forgetting what is added to the pasta

    The NHS daily salt guidance covers salt already in packaged foods as well as salt added during cooking or at the table.

    Account for additions such as cheese, stock or cured meat when assessing the whole lunch, and taste before adding salt.

  • Assuming every salt substitute is suitable

    North Bristol NHS Trust cautions that some substitutes contain potassium chloride and may not be suitable for people with kidney disease.

    If you have kidney disease or have been told to restrict potassium, ask your clinician or dietitian before using a salt substitute.

Brands to consider when comparing sauces

Dolmio

Dolmio offers Bolognese sauces and quicker stir-in formats for different pasta-lunch routines.

  • Dolmio publishes salt figures for specific sauces, allowing comparison per 100g and per stated portion.
  • Its Low Fat Bolognese and Tomato and Basil Stir In Sauce have different listed salt figures; neither 'low fat' nor 'stir-in' tells you which has less salt.

M&S

M&S lists nutrition, dietary and storage information for its Eat Well Tomato and Basil Pasta Sauce.

  • M&S lists 0.60g salt per 100g for this sauce and labels it vegan and vegetarian.
  • Check the physical pack before buying: M&S says recipes and nutrition information may change, and the cited sauce carries milk and egg allergy-suitability warnings.

Barilla

Barilla describes its 400g Basilico Sauce as a tomato-and-basil sauce that can be added to pasta.

  • Barilla identifies Italian tomatoes and basil in its description of this sauce.
  • Check the current pack's salt figure before treating Basilico Sauce as a lower-salt option.

Questions about salt and pasta sauce

How much salt should adults have in a day?

The NHS advises adults to have no more than 6g of salt a day. That includes salt in packaged foods and any added during cooking or at the table; it is general guidance rather than an individual dietary prescription.

How do I compare salt in two pasta sauces?

Compare their salt figures per 100g first, then calculate the salt in the amount you will actually use. A manufacturer's stated portion may differ from yours, so a per-portion figure alone may not describe your lunch.

Where can I find salt information without a traffic-light label?

Check the nutrition panel on the pack. GOV.UK notes that some supermarkets and manufacturers also display nutrition information on the front, so a front-of-pack traffic-light label should not be your only place to look.

Can I use a reduced-sodium salt substitute in pasta?

Check its ingredients and whether it suits your circumstances before using it. North Bristol NHS Trust cautions that some substitutes contain potassium chloride and may not be suitable for people with kidney disease; anyone advised to restrict potassium should ask a clinician or dietitian first.

How long can I keep an opened sauce jar?

Follow the instructions for the particular sauce. M&S says to refrigerate its Eat Well Tomato and Basil Pasta Sauce after opening and use it within three days, while its Daylesford Organic Tomato and Basil Sauce listing gives five days.
