Ok impractical for the masses, however I am not advocating it for the masses. I eat a high fruit diet because it works for me, I have grown berries here and had a couple peach trees and an apple tree before I went to live in the USA, you just have to take care of them and have the time of course. Dwarf trees are good because they produce a good amount.
It was easier living in Colorado to grow that stuff because of the heat, now I am back in the UK I eat slightly less fruit than I would have in Colorado because I don't always want to buy the imported stuff too often.
I suppose it will be easier again when I move somewhere warmer again one day
