It's the new book by Michael Pollan. Well, not
that new, but my name only just made it to the top of the library's waiting list. Here are some notes about the book (I'm terrible at writing reviews, so I wouldn't call it that) in case you're thinking of checking it out.
The book is basically an expansion of his article, "
Unhappy meals," that was supposed to be a condensation of everything we know about what you're supposed to eat. The conclusion, Pollan wrote, is that we don't know much besides that we should just eat our damn vegetables. Or as he put it, "Eat food. Not too much. Mostly plants." That slogan graces the bunch of leafy greens on the front of the book.
The book is, mainly, a critique of "nutritionism", the idea that one can proscribe what to eat based on what we know about the nutrients (fat, protein, vitamins, antioxidants, fiber, ...) present in those foods.
Pollan's conclusion is that the "western diet," with its processed foods and abundant sugars, is the problem. According to early research, almost every traditional diet is healthier than what Americans and Europeans have been eating for the past century or so.
So nutritionism benefits food producers (modifying the western diet to fit the latest theories), and possibly the medical establishment (they treat the results of the western diet) when really we should perhaps ditch the western diet altogether.
So the last chunk of the book is about determining
what is the diet we should subscribe to. Even many whole foods are now products of industry, both in how they're made (modern varieties of many crops produce greater yields but less density of the nutrients we can measure) and convenience and frequency (meat being available cheaply enough to be a regular part of the diet is part of why eating lots of meat, for example, doesn't quite fall under the "eat whole foods and everything will be fine" theory).
The uncomfortable conclusion is that there are no scientific proscriptions of what to eat. Previous cultures ate (a) what tasted good, (b) what their mother ate, (c) what was available. Seems like B and C are no longer reliable. Neither is A, actually, now that sweeteners, flavorings, and preservatives fool our senses.
Key quote:
"Food consists not just in piles of chemicals; it also comprises a set of social and ecological relationships, reaching back to the land and outward to other people. Some of [the book's recommendations] may strike you as having nothing whatever to do with health; in fact they do."
Pollan points out that food is too fast, too easy, and too cheap, saying we should go a little "backward" to a time when people spent more time and money on food, and also more time enjoying it.
This idea comes up often among slow-foodies, and the question I've gotta ask is, who's supposed to spend that time preparing it? Are we going "backward" to a time when the division of labor had a wife spend a chunk of her day on cooking and cleaning time while her husband did not?
That's what seems to happen, in practice, and we need to be careful that in our quest to eat better, we're not turning back the clock on other things too.
The last section of the book is a list of rules of thumb (with explanations) that will helpfully guide you toward the healthiest foods. As Pollan puts it: "Each proposes a different sort of map to the contemporary food landscape, but all should take you to more or less the same place."
The rules include seeking out plant foods, particularly ones that come from leaves rather than seeds, and seeking out meat (if you choose to eat any) that has eaten the same things. The footnotes contain lots of juicy information and resources, like a pointer to the "
Livestock's Long Shadow" report and
eatwild.com.
I take issue with some of the recommendations, like not to eat food your ancestors wouldn't have recognized (God help you if your ancestors were, say, Irish) and to take a multivitamin (Doesn't all that research say that vitamins do little good outside of the plants they come from?) ... but on the whole, the recommendations are good. Buy local and get to know the farmers. Eat a wide variety of foods, both for health and for biodiversity. No good food comes from a gas station. (This brings to mind the Futurama episode where Fry bought a sandwich from a men's room vending machine at a gas station. I won't spoil the ending, except to say the episode was entitled
Parasites Lost.)
Not much in this book is news to healthy locavores, but many will be startled by the major claim, that it doesn't matter what's in your food, so long as it's good food produced with health and ethics in mind. Nutrition labels, he reminds us, are an advertisement for "nutritionism" - the theory that a scientific analysis of foods' contents is the way to decide what to eat.
