There was a great slideshow article on the NY Times site this weekend called Food Rules: Your Dietary Dos and Don’ts curated by Michael Pollan. It’s 20 rules for eating, collected from readers and culled down to this manageable group.
They’re very interesting, especially some of the old family style rules like “It’s better to pay your grocer the doctor.” A lot of them touch on local and chemical free eating as well, and a surprising amount of just plain enjoying the food ideas.
