INTRODUCTION Our National Eating Disorder 

What should we have for dinner?

This book is a long and fairly involved answer to this seemingly simple question. Along the way, it also tries to figure out how such a simple question could ever have gotten so complicated. As a culture we seem to have arrived at a place where whatever native wisdom we may once have possessed about eating has been replaced by confusion and anxiety. Somehow this most elemental of activities—figuring out what to eat—has come to require a remarkable amount of expert help. How did we ever get to a point where we need investigative journalists to tell us where our food comes from and nutritionists to determine the dinner menu?

For me the absurdity of the situation became inescapable in the fall of 2002, when one of the most ancient and venerable staples of human life abruptly disappeared from the American dinner table. I’m talking of course about bread. Virtually overnight, Americans changed the way they eat. A collective spasm of what can only be described as carbophobia seized the country, supplanting an era of national lipophobia dating to the Carter administration. That was when, in 1977, a Senate committee had issued a set of “dietary goals” warning beef-loving Americans to lay off the red meat. And so we dutifully had done, until now.

What set off the sea change? It appears to have been a perfect media storm of diet books, scientific studies, and one timely magazine article. The new diet books, many of them inspired by the formerly discredited Dr. Robert C. Atkins, brought Americans the welcome news that they could eat more meat and lose weight just so long as they laid off the bread and pasta. These high-protein, low-carb diets found support in a handful of new epidemiological studies suggesting that the nutritional orthodoxy that had held sway in America since the 1970s might be wrong. It was not, as official opinion claimed, fat that made us fat, but the carbohydrates we’d been eating precisely in order to stay slim. So conditions were ripe for a swing of the dietary pendulum when, in the summer of 2002, the New York Times Magazine published a cover story on the new research entitled “What if Fat Doesn’t Make You Fat?” Within months, supermarket shelves were restocked and restaurant menus rewritten to reflect the new nutritional wisdom. The blamelessness of steak restored, two of the most wholesome and uncontroversial foods known to man—bread and pasta—acquired a moral stain that promptly bankrupted dozens of bakeries and noodle firms and ruined an untold number of perfectly good meals.

So violent a change in a culture’s eating habits is surely the sign of a national eating disorder. Certainly it would never have happened in a culture in possession of deeply rooted traditions surrounding food and eating. But then, such a culture would not feel the need for its most august legislative body to ever deliberate the nation’s “dietary goals”—or, for that matter, to wage political battle every few years over the precise design of an official government graphic called the “food pyramid.” A country with a stable culture of food would not shell out millions for the quackery (or common sense) of a new diet book every January. It would not be susceptible to the pendulum swings of food scares or fads, to the apotheosis every few years of one newly discovered nutrient and the demonization of another. It would not be apt to confuse protein bars and food supplements with meals or breakfast cereals with medicines. It probably would not eat a fifth of its meals in cars or feed fully a third of its children at a fast-food outlet every day. And it surely would not be nearly so fat.

Nor would such a culture be shocked to discover that there are other countries, such as Italy and France, that decide their dinner questions on the basis of such quaint and unscientific criteria as pleasure and tradition, eat all manner of “unhealthy” foods, and, lo and behold, wind up actually healthier and happier in their eating than we are. We show our surprise at this by speaking of something called the “French paradox,” for how could a people who eat such demonstrably toxic substances as foie gras and triple crème cheese actually be slimmer and healthier than we are? Yet I wonder if it doesn’t make more sense to speak in terms of an American paradox—that is, a notably unhealthy people obsessed by the idea of eating healthily.

 

TO ONE DEGREE or another, the question of what to have for dinner assails every omnivore, and always has. When you can eat just about anything nature has to offer, deciding what you should eat will inevitably stir anxiety, especially when some of the potential foods on offer are liable to sicken or kill you. This is the omnivore’s dilemma, noted long ago by writers like Rousseau and Brillat-Savarin and first given that name thirty years ago by a University of Pennsylvania research psychologist named Paul Rozin. I’ve borrowed his phrase for the title of this book because the omnivore’s dilemma turns out to be a particularly sharp tool for understanding our present predicaments surrounding food.

In a 1976 paper called “The Selection of Foods by Rats, Humans, and Other Animals” Rozin contrasted the omnivore’s existential situation with that of the specialized eater, for whom the dinner question could not be simpler. The koala doesn’t worry about what to eat: If it looks and smells and tastes like a eucalyptus leaf, it must be dinner. The koala’s culinary preferences are hardwired in its genes. But for omnivores like us (and the rat) a vast amount of brain space and time must be devoted to figuring out which of all the many potential dishes nature lays on are safe to eat. We rely on our prodigious powers of recognition and memory to guide us away from poisons (Isn’t that the mushroom that made me sick last week?) and toward nutritious plants (The red berries are the juicier, sweeter ones). Our taste buds help too, predisposing us toward sweetness, which signals carbohydrate energy in nature, and away from bitterness, which is how many of the toxic alkaloids produced by plants taste. Our inborn sense of disgust keeps us from ingesting things that might infect us, such as rotten meat. Many anthropologists believe that the reason we evolved such big and intricate brains was precisely to help us deal with the omnivore’s dilemma.

Being a generalist is of course a great boon as well as a challenge; it is what allows humans to successfully inhabit virtually every terrestrial environment on the planet. Omnivory offers the pleasures of variety, too. But the surfeit of choice brings with it a lot of stress and leads to a kind of Manichaean view of food, a division of nature into The Good Things to Eat, and The Bad.

The rat must make this all-important distinction more or less on its own, each individual figuring out for itself—and then remembering—which things will nourish and which will poison. The human omnivore has, in addition to his senses and memory, the incalculable advantage of a culture, which stores the experience and accumulated wisdom of countless human tasters before him. I don’t need to experiment with the mushroom now called, rather helpfully, the “death cap,” and it is common knowledge that that first intrepid lobster eater was on to something very good. Our culture codifies the rules of wise eating in an elaborate structure of taboos, rituals, recipes, manners, and culinary traditions that keep us from having to reenact the omnivore’s dilemma at every meal.

One way to think about America’s national eating disorder is as the return, with an almost atavistic vengeance, of the omnivore’s dilemma. The cornucopia of the American supermarket has thrown us back on a bewildering food landscape where we once again have to worry that some of those tasty-looking morsels might kill us. (Perhaps not as quickly as a poisonous mushroom, but just as surely.) Certainly the extraordinary abundance of food in America complicates the whole problem of choice. At the same time, many of the tools with which people historically managed the omnivore’s dilemma have lost their sharpness here—or simply failed. As a relatively new nation drawn from many different immigrant populations, each with its own culture of food, Americans have never had a single, strong, stable culinary tradition to guide us.

The lack of a steadying culture of food leaves us especially vulnerable to the blandishments of the food scientist and the marketer, for whom the omnivore’s dilemma is not so much a dilemma as an opportunity. It is very much in the interest of the food industry to exacerbate our anxieties about what to eat, the better to then assuage them with new products. Our bewilderment in the supermarket is no accident; the return of the omnivore’s dilemma has deep roots in the modern food industry, roots that, I found, reach all the way back to fields of corn growing in places like Iowa.

And so we find ourselves where we do, confronting in the supermarket or at the dinner table the dilemmas of omnivorousness, some of them ancient and others never before imagined. The organic apple or the conventional? And if the organic, the local one or the imported? The wild fish or the farmed? The trans fats or the butter or the “not butter”? Shall I be a carnivore or a vegetarian? And if a vegetarian, a lacto-vegetarian or a vegan? Like the hunter-gatherer picking a novel mushroom off the forest floor and consulting his sense memory to determine its edibility, we pick up the package in the supermarket and, no longer so confident of our senses, scrutinize the label, scratching our heads over the meaning of phrases like “heart healthy,” “no trans fats,” “cage-free,” or “range-fed.” What is “natural grill flavor” or TBHQ or xanthan gum? What is all this stuff, anyway, and where in the world did it come from?

 

MY WAGER in writing The Omnivore’s Dilemma was that the best way to answer the questions we face about what to eat was to go back to the very beginning, to follow the food chains that sustain us, all the way from the earth to the plate—to a small number of actual meals. I wanted to look at the getting and eating of food at its most fundamental, which is to say, as a transaction between species in nature, eaters and eaten. (“The whole of nature,” wrote the English author William Ralph Inge, “is a conjugation of the verb to eat, in the active and passive.”) What I try to do in this book is approach the dinner question as a naturalist might, using the long lenses of ecology and anthropology, as well as the shorter, more intimate lens of personal experience.

My premise is that like every other creature on earth, humans take part in a food chain, and our place in that food chain, or web, determines to a considerable extent what kind of creature we are. The fact of our omnivorousness has done much to shape our nature, both body (we possess the omnicompetent teeth and jaws of the omnivore, equally well suited to tearing meat and grinding seeds) and soul. Our prodigious powers of observation and memory, as well as our curious and experimental stance toward the natural world, owe much to the biological fact of omnivorousness. So do the various adaptations we’ve evolved to defeat the defenses of other creatures so that we might eat them, including our skills at hunting and cooking with fire. Some philosophers have argued that the very open-endedness of human appetite is responsible for both our savagery and civility, since a creature that could conceive of eating anything (including, notably, other humans) stands in particular need of ethical rules, manners, and rituals. We are not only what we eat, but how we eat, too.

Yet we are also different from most of nature’s other eaters—markedly so. For one thing, we’ve acquired the ability to substantially modify the food chains we depend on, by means of such revolutionary technologies as cooking with fire, hunting with tools, farming, and food preservation. Cooking opened up whole new vistas of edibility by rendering various plants and animals more digestible, and overcoming many of the chemical defenses other species deploy against being eaten. Agriculture allowed us to vastly multiply the populations of a few favored food species, and therefore in turn our own. And, most recently, industry has allowed us to reinvent the human food chain, from the synthetic fertility of the soil to the microwaveable can of soup designed to fit into a car’s cup holder. The implications of this last revolution, for our health and the health of the natural world, we are still struggling to grasp.

The Omnivore’s Dilemma is about the three principal food chains that sustain us today: the industrial, the organic, and the hunter-gatherer. Different as they are, all three food chains are systems for doing more or less the same thing: linking us, through what we eat, to the fertility of the earth and the energy of the sun. It might be hard to see how, but even a Twinkie does this—constitutes an engagement with the natural world. As ecology teaches, and this book tries to show, it’s all connected, even the Twinkie.

Ecology also teaches that all life on earth can be viewed as a competition among species for the solar energy captured by green plants and stored in the form of complex carbon molecules. A food chain is a system for passing those calories on to species that lack the plant’s unique ability to synthesize them from sunlight. One of the themes of this book is that the industrial revolution of the food chain, dating to the close of World War II, has actually changed the fundamental rules of this game. Industrial agriculture has supplanted a complete reliance on the sun for our calories with something new under the sun: a food chain that draws much of its energy from fossil fuels instead. (Of course, even that energy originally came from the sun, but unlike sunlight it is finite and irreplaceable.) The result of this innovation has been a vast increase in the amount of food energy available to our species; this has been a boon to humanity (allowing us to multiply our numbers), but not an unalloyed one. We’ve discovered that an abundance of food does not render the omnivore’s dilemma obsolete. To the contrary, abundance seems only to deepen it, giving us all sorts of new problems and things to worry about.

Each of this book’s three parts follows one of the principal human food chains from beginning to end: from a plant, or group of plants, photosynthesizing calories in the sun, all the way to a meal at the dinner end of that food chain. Reversing the chronological order, I start with the industrial food chain, since that is the one that today involves and concerns us the most. It is also by far the biggest and longest. Since monoculture is the hallmark of the industrial food chain, this section focuses on a single plant: Zea mays, the giant tropical grass we call corn, which has become the keystone species of the industrial food chain, and so in turn of the modern diet. This section follows a bushel of commodity corn from the field in Iowa where it grew on its long, strange journey to its ultimate destination in a fast-food meal, eaten in a moving car on a highway in Marin County, California.

The book’s second part follows what I call—to dis...

What should we have for dinner?" To one degree or another this simple question assails any creature faced with a wide choice of things to eat. Anthropologists call it the omnivore's dilemma. Choosing from among the countless potential foods nature offers, humans have had to learn what is safe, and what isn't—which mushrooms should be avoided, for example, and which berries we can enjoy. Today, as America confronts what can only be described as a national eating disorder, the omnivore's dilemma has returned with an atavistic vengeance. The cornucopia of the modern American supermarket and fast-food outlet has thrown us back on a bewildering landscape where we once again have to worry about which of those tasty-looking morsels might kill us. At the same time we're realizing that our food choices also have profound implications for the health of our environment. The Omnivore's Dilemma is bestselling author Michael Pollan's brilliant and eye-opening exploration of these little-known but vitally important dimensions of eating in America.

Pollan has divided The Omnivore's Dilemma into three parts, one for each of the food chains that sustain us: industrialized food, alternative or "organic" food, and food people obtain by dint of their own hunting, gathering, or gardening. Pollan follows each food chain literally from the ground up to the table, emphasizing our dynamic coevolutionary relationship with the species we depend on. He concludes each section by sitting down to a meal—at McDonald's, at home with his family sharing a dinner from Whole Foods, and in a revolutionary "beyond organic" farm in Virginia. For each meal he traces the provenance of everything consumed, revealing the hidden components we unwittingly ingest and explaining how our taste for particular foods reflects our environmental and biological inheritance.

We are indeed what we eat-and what we eat remakes the world. A society of voracious and increasingly confused omnivores, we are just beginning to recognize the profound consequences of the simplest everyday food choices, both for ourselves and for the natural world. The Omnivore's Dilemma is a long-overdue book and one that will become known for bringing a completely fresh perspective to a question as ordinary and yet momentous as What shall we have for dinner?

A few facts and figures from The Omnivore's Dilemma:

• Of the 38 ingredients it takes to make a McNugget, there are at least 13 that are derived from corn. 45 different menu items at Mcdonald’s are made from corn.

• One in every three American children eats fast food every day.

• One in every five American meals today is eaten in the car.

• The food industry burns nearly a fifth of all the petroleum consumed in the United States—more than we burn with our cars and more than any other industry consumes.

• It takes ten calories of fossil fuel energy to deliver one calorie of food energy to an American plate.

• A single strawberry contains about five calories. To get that strawberry from a field in California to a plate on the east coast requires 435 calories of energy.

• Industrial fertilizer and industrial pesticides both owe their existence to the conversion of the World War II munitions industry to civilian uses—nerve gases became pesticides, and ammonium nitrate explosives became nitrogen fertilizers.
