Your Grandad sounds great!
Maybe there could be a pacifist, vegan version of the scouts or army cadets, where kids get sent off camping and learn to live off mushrooms and fruit and stuff?
I think you are probably right that kids should learn about being healthy. Maybe if kids get used to eating healthy food when they are very young, they won't refuse to eat it later? I don't know many kids...
Or maybe they'll rebel

some kids in my home town were never allowed to eat sweets, because their father was a dentist. As soon as they got out of the house, they went crazy and ate all the sweets they could find...
