What should we have for dinner? For omnivore like ourselves, this simple question has always posed a dilemma. When you can eat just about anything nature (or the supermarket) has to offer, deciding what you should eat will inevitably stir anxiety, especially when some of the foods on offer might shorten your life. Today, buffered by one food fad after another, America is suffering from what can only be described as a national eating disorder. The omnivore’s dilemma has returned with a vengeance, as the cornucopia of the modern American supermarket and fast-food outlet confronts us with a bewildering and treacherous food landscape. What’s at stake in our eating choices is not only our own and our children’s health, but the health of the environment that sustains life on earth.
