I don't think "eat melon rinds because they have fiber" is quite the culinary education you seem to think it is.
I'm from Portugal, known for the Mediterranean Diet, and from what I see here compared to living in countries like Britain, culinary education is not about using the unpleasant parts of veggies for their fiber, it's using fresh veggies in the first place.
That's the problem I saw with the poor in Britain - they'll eat lots of cheap carbs and not enough vegetables.
Using the unpleasant parts of the veggies for fiber (which is not a nutrient as the human body cannot break it up or absorb it, it's just filling and keeps your digestive system clean) is just poverty.
This article is definitelly not about teaching people to eat the right things.
