All 21.7g of sugar per 100g in Triple Chocolate Crunch counts as free sugar, because it comes from added sugars rather than whole fruit or milk. A 30g bowl gives 6.5g, about 1.6 teaspoons.
Triple Chocolate Crunch is classed as NOVA 4, ultra-processed, because its ingredients include whey, emulsifier, lecithin, flavouring, fructo-oligosaccharide, glucose syrup and caramelised sugar. These are industrial ingredients you would not use in a home kitchen. 7 of its 21 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.
