"But imagine for a moment if we once again knew, strictly as a matter of course, these few unremarkable things: What it is we're eating. Where it came from. How it found its way to our table. And what, in a true accounting, it really cost. We could then talk about some other things at dinner. For we would no longer need any reminding that however we choose to feed ourselves, we eat by the grace of nature, not industry, and what we're eating is never anything more or less than the body of the world."
--Michael Pollan, "The Omnivore's Dilemma"
May I recommend to you this beautiful, enlightening, and provocative book.
And may I recommend that you really chew on it, really let it get inside you (like a good meal).
And then may I recommend that you make a change, some small change or large,
in recognition of the fact that eating can be a political act.
Choose something whole instead of processed.
