Then again, the advice really just cashes out into buying whole foods like produce, beans, frozen bags of veggies, etc. Better food items will get caught in the crossfire of someone naively avoiding the worse "processed foods", but maybe that's still a net win. Even your fancy nuts example, if one of the main problems with ultra-processed foods is that they are hyperpalatable, then I see good reason to avoid fancy nuts (nuts with an oil + salt coating) and eating raw nuts instead. It's easy enough to overeat raw nuts!
