Popular food sauces from Dolmio and Uncle Ben's should not be eaten more than once a week because they are so high in salt, fat and sugar - the company that makes them has told customers.
Mars Food will divide its range into products that can be eaten every day or only occasionally as part of a scheme to encourage healthier eating.
Dolmio lasagne sauces, creamy tomato pasta bake kits and pesto will be among those labelled as "occasional" treats, according to the Guardian newspaper.
The firm will also cut the amount of salt and sugar used in some of its recipes and increase the use of whole grains.
Shoppers will begin to see the new guidance appearing on websites within the next few months.
Fiona Dawson, the global president of Mars Food, Drinks and Multisales, said:
To maintain the authentic nature of the recipe, some Mars Food products are higher in salt, added sugar or fat.
