I shop less and less - used to be a few times a week, now once a week max. I plan to cut back more now that I am not eating a ton of salads. And I think it's the only way to really break the habit of always buying produce. I buy all my meat direct from the ranch once a month. Seafoods I buy every week or 2, depending on season. I have made a commitment to only buy organic foods at any store. If I can't find something organic, I go without. I buy a good amount online too; like herbs and spices from Mountain Rose Herb, seaweeds from Maine Coast Sea Vegetables & Eastern Sun, dried fruits (for the kids) and gluten free tamari at Gold Mine, and olives and nuts from Sun Organics. But again, I am eating mainly animal foods, and the majority of those are raw, as is most any plant food I buy. Plant foods I eat are mainly fruits. So they are like condiments to my meat meals, basically.
I also plan to grow more of my own herbs and fruits, like pickling cucumbers this spring to make my own lacto-fermented pickles. That way, they are raw, naturally preserved and all that jazz. I have peach, plum and apricot trees and blackberries. If I get loads of fruit this year, I will dry some of it. Apricots I just lurve! That way, I am staying away from major, industrial foods, organic or not, for the most part.
I may never make it zero carb (obviously), but I am not going to Whole Foods to buy salad greens and such out of season from some greenhouse in CA any longer. Instead, I will buy raw, sun dried olives once every six months from CA or something. If there are chives in the garden, great. If not, then I go without. That is my intention, and there is a huge amount of freedom involved in not having to go shop all the freakin' time. I live some distance from major health food stores anyway.
