A 30g bowl of M&S Mixed Berry Muesli contains 105 kcal, 6.0g of sugar (2.1g of free sugar), 2.6g of fibre and 2.7g of protein. With 125ml of semi-skimmed milk the bowl comes to 163 kcal and 11.9g of total sugar. It is classed as NOVA 3 (processed).
Of the 20.0g of sugar per 100g in Mixed Berry Muesli, Boone counts 7.0g as free sugar. The rest (13.0g) is sugar in whole dried fruit, which the NHS limit does not count. Method: total sugar less 13.0g from whole dried fruit (estimated where the pack gives no percentage).
Mixed Berry Muesli 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.
