Judging by a survey that turned up in my email one morning, Michael Pollan has his work cut out for him in trying to persuade Americans to eat primarily from the perimeter of supermarkets. Of the top 10 sales categories, only milk, bread and eggs are showcased in the healthful real estate. Cereal, cookies, canned soup, chocolate candy and potato chips were the other “foods” on the list, and I just read that and heard Fat Albert hey-hey-heying his way toward the deli. Why do I suspect cloned meat is the least of the threats to the food chain?
