> The kids get involved early in learning about healthy food making and we get a cook book about what sort of food one should make for children when they start school.

How frequently is this curriculum revised and how are updates communicated to children after they graduate from that course/class/curriculum?

I'm mostly curiously because of how dietary research has changed and because there is little consensus on what a "bad" diet is. Almost everyone will agree to avoid sugar and processed food, but that's about where it ends. You also have to factor in individual genetics and lifestyle, although perhaps less so in countries like Norway where there would be a common genetic ancestry.
