Author of “The Omnivore’s Dilemma” and, more recently, “In Defense of Food,” Michael Pollan writes in support of healthful, natural foods and against corporate farms and highly processed American edibles. Pollan appears in the new movie “Food Inc.,” which, as one critic said, “does for the supermarket what ‘Jaws’ did for the beach.” Here are the seven precepts Michael Pollan promotes:

• Don’t eat anything your great-grandmother wouldn’t recognize as food — yogurt tubes, for example.

• Don’t eat anything with more than five ingredients, or ingredients you can’t pronounce.

• Stay out of the middle of the supermarket; shop on the perimeter, where real food tends to be located.

• Don’t eat anything that won’t eventually rot (e.g., Twinkies). Honey might be the only exception.

• Always leave the table a little hungry.

• Enjoy meals with the people you love.

• Don’t buy food where you buy your gasoline.
