Serious Eats: Michael Pollan's Twelve Commandments for Serious Eaters: Can You Live By Them?:
"7. 'Pay more, eat less.' Easy for him—or anybody else with enough discretionary spending power—to say. Not so easy for the working poor or even middle class folks who have very little extra money for anything.
8. "Eat a wide variety of species." But can't I eat heritage pork products more often than others?
9. "Eat food from animals that eat grass." As long as these animals can occasionally be finished on corn. Sorry, Michael: Beef from cows that eat grass and then corn taste better. "

A fairly snarky post at Serious Eats about Micheal Pollan's latest book. I haven't read the book so I can't comment on how forceful Pollan posits these "commandments" or even if he calls them that. But I think the point of #7 is to rearrange our priorities and change our perception regarding the true cost of our food. We have had artificially cheap food for decades and have gotten to expect it to stay that way forever. You can pay more simply by buying conventional produce rather than processed foods. You don't HAVE to buy organic, hand grown heritage stuff to make a difference. #9's comment that corn fed beef tastes better is ludicrous. Of course it is a matter of personal taste, but grass fed beef is WAY more flavorful than even prime corn fed beef for my money. The #8 comment as well as many others in the article, have to be considered as jokes taking Pollans' words way too literally and seriously. He's not after absolutes here. But much like Jesus' Golden Rule ("do unto others...") that "sums up The Law and The Prophets", Pollan HAS offered a succinct summary of his work: "Eat food. Not too much. Mostly plants."
