I'm currently at about 10% of my food (youngish family of 7), thanks mainly to super productive chickens. That percentage is creeping up as we figure out how to work with our small goat herd. Goat meat is already putting a dent in our meat budget; just need the dairy to replace grocery milk and eventually butter/cheese/yogurt. Been struggling with disease in our meat rabbits, but once that's fixed we'll be able to add rabbit meat, and, along with the occasional duck and fish from our pond, our animal product needs will be totally self-sourced.
Our fruit and vegetables are still mostly grocery buys, but I can see phasing that out over the next few years as our fruit trees and perennial garden get bigger and more established and we find out which kind of annual bumper crops will survive the neglect and pest pressure in our area. So far Jerusalem artichokes, chinese yams, sweet potatoes, asparagus, blueberries, mulberries, figs, tomatoes and okra all do consistently well, but we haven't established good systems for preserving them to cover the whole year. We also have pecans and chestnuts that we mostly leave to the animals which we plan to start keeping for ourselves.
Nothing in the works yet to replace grocery sugar - my eldest daughter is keen to start bees next year to rectify that.
Cereals are a major part of our diet and daunting to replace on our 5 acre, part-time human powered operation. My hope is that we can make grain amaranth - which grows easily, vigorously and self-seeds in our area - a staple in our diet, but it has to pass the "can't be a huge pain to process" and "tastes good" tests. Also doing some experiments with lotus and growing corn on chinampa style floats on our pond to add to our grain arsenal.
