I can't remember a time in my life that I was not a forager, but it was almost completely not on the lot I lived on. Now I forage almost exclusively in my food forests. One big change to my eating habits is with the pulses of new foods. I end up heavy grazing on whatever is ripening. Lots of spontaneous fruit gorging. Just wrapping up now on kiwis and apples. Sunroom is drying up herbs and a batch of chestnuts for flour making. I need to process a mound of pawpaws and another of flowering quinces. Autumn olives are begging to be made into fruit leather. Besides so many new foods, the way I eat now has been strongly influenced by what is ready outside my door. Less planning and more reacting. More off the cuff cooking.
I do still eat from the store. Currently dealing with mild food poisoning from a recall that was a day too late for me. Hmmm. Maybe my next permaculture food change is to give up on our food distribution system. My food forest has never made me sick.
