A 30g bowl of M&S Sultana Bran Flakes contains 101 kcal, 7.5g of sugar (1.9g of free sugar), 4.5g of fibre and 3.0g of protein. With 125ml of semi-skimmed milk the bowl comes to 160 kcal and 13.4g of total sugar. It is classed as NOVA 3 (processed).
Of the 25.0g of sugar per 100g in Sultana Bran Flakes, Boone counts 6.4g as free sugar. The rest (18.6g) is sugar in whole dried fruit, which the NHS limit does not count. Method: total sugar less 18.6g from whole dried fruit.
Sultana Bran Flakes is classed as NOVA 3, processed. It is made from grains or other whole foods with culinary ingredients such as sugar, salt, oil or malt extract added, but none of the industrial ingredients that mark a food as ultra-processed.
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.
