Cereals are ranked by free sugar per 100g, not total sugar. Free sugars are the sugars NHS daily limits apply to: added sugar, honey, syrups and fruit juice. Sugar that comes from whole or dried fruit and from milk is not free sugar, so a fruit muesli can have plenty of total sugar but less free sugar.

Boone works out free sugar from the ingredients list and nutrition panel on Sainsbury's own-brand listings. Porridge pots are labelled for the pot made up with water; Boone has converted them to the dry contents so they compare fairly. The percentages are for a 30g serving against the daily limit for the age you pick: 30g for anyone 11 or over, 24g for 7 to 10 year olds and 19g for 4 to 6 year olds. Milk is not included.

Frequently asked questions

Which Sainsbury's own-brand cereal has the most sugar?+

Sainsbury's Honey Nut Cornflakes, with 29.2g of free sugar per 100g. A 30g serving gives 8.8g, 29% of an adult's daily limit and 46% of a 4 to 6 year old's.

Which Sainsbury's own-brand cereals have no free sugar?+

16 of them, including Sainsbury's Free From Oats, Sainsbury's Free From Original Porridge Pot, Sainsbury's Fruit, Nut & Seed Muesli, Sainsbury's Fruity Muesli. Any sugar they contain comes from the grain, whole dried fruit or milk.

Why rank free sugar instead of total sugar?+

NHS daily limits apply to free sugars only. Sugar inside whole or dried fruit does not count, so a muesli with raisins can show a high total sugar on the box but much less free sugar.

How much free sugar should children have?+

No more than 19g a day for 4 to 6 year olds, 24g for 7 to 10 year olds and 30g from age 11. Use the age buttons to see each cereal against those limits.

Where does this data come from?+

The nutrition panels and ingredients lists on Sainsbury's own-brand cereal listings at sainsburys.co.uk, collected in October 2026. Branded cereals sold at Sainsbury's, such as Kellogg's or Weetabix, are not included. Boone works out free sugar, manufactured ingredients and nutrient profiling scores from them.
