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 Tesco own-brand listings. Easy Oats sachets are labelled for the sachet made up with semi-skimmed milk and the Instant Oats pot 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.
