There are many ways to eat more or less local food, via producers. If you take France for example, it could easily be self-sufficient in fruits/vegetables (currenly it's not because of how they destroyed the beautiful old agriculture (orchards, permacultures) to grow intensive monocultures of corn and things for industrial derived products instead (they are less efficient by yield/surface, and much more demanding in resources, more polluting, creates more erosion, kill life in the soil,..).
