  1. MP unprocessed and minimally processed, PCI processed culinary ingredients, P processed; ULP ultra-processed, Med median, MLNSE meat, legumes, nuts, seeds and eggs, FSF formulated supplementary foods; (%) percentage of products classified in each NOVA category within ADG food group categories
  2. *value = 2.2; **value = 1.25 (due to the number of products in these categories a median HSR could not be calculated)
  3. δmedian significantly different to median of UP foods within the same ADG group (Mann Whitney U test, p < 0.05)
