It isn't super detailed as far as I remember. It is more about the really obvious stuff like eating less processed and whole foods. So e.g. they will make whole grain bread, cut raw vegtables, maybe make vegtable soup, avoid stuff with lots of added sugar.

As far as I know the debate about health eating has centered around how much carbo hydrates we should eat and the role of fat. But I think eating less processed food, more whole grain and less sugar has always been accepted wisdom about healthy eating.

We Norwegians probably eat a bit much bread and potatoes and should probably eat more vegtables and alternatives such as beans, lentils etc. However I think we've been fairly good at avoiding too much sweets in the diet.
