I'm as concerned by the question of what people don't eat as what they do. Is it the processed food that's the issue, or is it the lack of those foods that it displaced? Fruit, veg, complex carbs being squeezed out by sugary drinks, burgers and bread. I think sometimes the headline message can be actually destructive, because it can just sound like it's a list of things you enjoy - and it just sounds like someone trying to suck the fun and the flavour out of life, which is easy to ignore and dismiss as "I'd rather be happy".
I notice that if for some reason I'm eating less fruit, I start to want sweet food like cakes and chocolate that normally I ignore. If I focus on what I should eat, the desire for the what I shouldn't eat actually declines. If I've just cooked some really tasty veggies the last thing I want to see on the plate is something like a hotdog. Despite the fact that occasionally, particularly at an outdoor event, a hotdog is something I really do enjoy.
