A 30g bowl of Sainsbury's Multigrain Hoops contains 114 kcal, 5.0g of sugar (all of it free sugar), 2.6g of fibre and 2.9g of protein. With 125ml of semi-skimmed milk the bowl comes to 173 kcal and 10.9g of total sugar. It is classed as NOVA 4 (ultra-processed).
All 16.8g of sugar per 100g in Multigrain Hoops counts as free sugar, because it comes from added sugars rather than whole fruit or milk. A 30g bowl gives 5.0g, about 1.3 teaspoons.
Multigrain Hoops is classed as NOVA 4, ultra-processed, because its ingredients include wheat starch, caramelised sugar, flavouring and colour. These are industrial ingredients you would not use in a home kitchen. 5 of its 13 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.
