A 30g bowl of Sainsbury's Nut Flakes & Clusters contains 130 kcal, 3.8g of sugar (all of it free sugar), 2.3g of fibre and 3.1g of protein. With 125ml of semi-skimmed milk the bowl comes to 189 kcal and 9.7g of total sugar. It is classed as NOVA 4 (ultra-processed).
All 12.7g of sugar per 100g in Nut Flakes & Clusters counts as free sugar, because it comes from added sugars rather than whole fruit or milk. A 30g bowl gives 3.8g, about 1.0 teaspoons.
Nut Flakes & Clusters is classed as NOVA 4, ultra-processed, because its ingredients include emulsifier, mono- and diglycerides, caramelised sugar, corn starch, flavouring and caramel. These are industrial ingredients you would not use in a home kitchen. 5 of its 22 ingredients are of this kind.
Boone classifies processing from the published ingredient list using the NOVA system. Added vitamins and minerals are not counted as a marker of ultra-processing.
