Call it the 100/200/500 mile diet and in theory it sounds like a great idea, but how practical is it? Do you like to drink coffee, well I guess we’ll make an exception for that. Salt, Pepper, and Spices another exception. I’m Celiac (means I can’t have Gluten) so where do I get my Rice/Tapioca/Corn etc. flours? Another exception? It really isn’t practical to limit yourself to a local region for your complete food supply unless you don’t mind strictly eating the same bland food day after day after day.
I do believe that where I live in Alberta, Canada produces some of the best root crops and meats anywhere in the world so why would I get my beef from New Zealand or my potatoes from Idaho? That wouldn’t make sense. I think getting what is available locally and helping support local farmers is very important, but it is equally important to supplement that local produce with the wide diversity this planet has to offer.
Buying local shouldn’t be a fad as it seems to be with famous chefs only using what they can find within x amount of miles (they always forget to point out that they are in a temperate area with a year round growing season and growers growing crops exclusively for them).
Buy local where you can, but don’t let you taste buds down by limiting yourself to only that which is local. Life is too short to not try to taste it all.
