I don’t follow a specific diet. I do follow one ethical precept to eating and that is nonviolence— towards non-human animals, of course, but also to human animals, including myself.
in practice, that translates to eating sustainable, organic and locally sourced (or fairly traded). I’m a dietary vegan most of the time but occasionally use cultured dairy and ghee, when I know I can trust where it came from and how the cows were treated. (they are holy, after all!)
I’d say the most important aspect to my diet— which also relates to nonharming in a very direct way— is truly listening to my body and following its instincts & intuitions (e.g. more foods high in potassium/iron/b-vitamins; avoid raw nuts, gluten, refined oils). you get the picture. tmi, probably. in short:
