Michael Pollan: Don't Eat Anything That Doesn't Rot

Acclaimed author and journalist Michael Pollan argues that what most Americans are consuming today is not food but "edible foodlike substances." His previous book, The Omnivore's Dilemma: A Natural History of Four Meals, was named one of 2006's ten best books by the New York Times and the Washington Post. His latest book is called In Defense of Food: An Eater's Manifesto.

Amy Goodman:"You are what to eat." Or so the saying goes. In American culture, healthy food is a national preoccupation. But then, why are Americans becoming less healthy and more overweight?

Michael Pollan joined me for a wide-ranging conversation about nutrition, food science and the current American diet. I began by asking him why he feels he has to defend food.

Michael Pollan: Food's under attack from two quarters. It's under attack from the food industry, which is taking, you know, perfectly good whole foods and tricking them up into highly processed edible foodlike substances, and from nutritional science, which has over the years convinced us that we shouldn't be paying attention to food, it's really the nutrients that matter. And they're trying to replace foods with antioxidants, you know, cholesterol, saturated fat, omega-3s, and that whole way of looking at food as a collection of nutrients, I think, is very destructive.

Goodman: Shouldn't people be concerned, for example, about cholesterol?

Pollan: No. Cholesterol in the diet is actually only very mildly related to cholesterol in the blood. It was a -- that was a scientific error, basically. We were sold a bill of goods that we should really worry about the cholesterol in our food, basically because cholesterol is one of the few things we could measure that was linked to heart disease, so there was this kind of obsessive focus on cholesterol. But, you know, the egg has been rehabilitated. You know, the egg is very high in cholesterol, and now we're told it's actually a perfectly good, healthy food. So there's only a very tangential relationship between the cholesterol you eat and the cholesterol levels in your blood.

Goodman: How is it that the food we eat now, it takes time to read the ingredients?

Pollan: Yeah.

Goodman: You actually have to stop and spend time and perhaps put on glasses or figure out how to pronounce words you have never heard of.

Pollan: Yeah, it's a literary scientific experience now going shopping in the supermarket, because basically the food has gotten more complex. It's -- for the food industry -- see, to understand the economics of the food industry, you can't really make money selling things like, oh, oatmeal, you know, plain rolled oats. And if you go to the store, you can buy a pound of oats, organic oats, for 79 cents. There's no money in that, because it doesn't have any brand identification. It's a commodity, and the prices of commodity are constantly falling over time.

So you make money by processing it, adding value to it. So you take those oats, and you turn them into Cheerios, and then you can charge four bucks for that 79 cents -- and actually even less than that, a few pennies of oats. And then after a few years, Cheerios become a commodity. You know, everyone's ripping off your little circles. And so, you have to move to the next thing, which are like cereal bars. And now there's cereal straws, you know, that your kids are supposed to suck milk through, and then they eat the straw. It's made out of the cereal material. It's extruded.

So, you see, every level of further complication gives you some intellectual property, a product no one else has, and the ability to charge a whole lot more for these very cheap raw ingredients. And as you make the food more complicated, you need all these chemicals to make it last, to make it taste good, to make -- and because, you know, food really isn't designed to last a year on the shelf in a supermarket. And so, it takes a lot of chemistry to make that happen.
