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 Ocado's M&S listings. 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 M&S cereal has the most sugar?+

M&S Honey Nut Corn Flakes, with 26.6g of free sugar per 100g. A 30g serving gives 8g, 27% of an adult's daily limit and 42% of a 4 to 6 year old's.

Which M&S cereals have no free sugar?+

14 of them, including M&S Jumbo Oats, M&S Made Without Fruit & Nut Muesli, M&S Made Without Traditional Porridge Oats, M&S Mango & Warm Spices Overnight Oats. 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 Ocado's M&S own-label cereal listings, collected in October 2026. Boone works out free sugar, manufactured ingredients and nutrient profiling scores from them.
