It's a question I consider frequently. My health response to my n=1 trials and tests helping me adapt to a sound WOE gives me answers to recognize the correct path. I filter out the external claims of certain dietary acolytes because they don't relate to me. It's an interesting quandary, however, being human, maintaining a state of consciousness awareness/ mindfulness, maintaining a healthy WOE, and respecting all forms of life (including plant life) all at once.

Edit: I don't get concerned with those who criticize others' behaviors, as I've personally reconciled perceived issues with my own approach.
