Because for example grape juice has more sugar per cup than coca-cola, and almost no nutrients (if filtered.) And yet it's firmly the best type of food according to NOVA system (minimal processing, no artificial additives). You can be sure that if any sort of government adopts NOVA system, it's that kind of food that would be pushed to consumer, not the actual healthy stuff.
