  1. a These sub-categories correspond to the food categories for which a distinction was made by the degree of processing. Raw foods corresponded to NOVA 1 group, processed foods to NOVA 2 group and ultra-processed foods to NOVA 4 group. No product from NOVA 3 group was found for the ‘Meat’ category, resulting in only two sub-categories
