…a tough, witty, cogent rebuttal to the proposition that food can be reduced to its nutritional components without the loss of something essential…In this lively, invaluable book—which grew out of an essay Mr. Pollan wrote for The New York Times Magazine, for which he is a contributing writer—he assails some of the most fundamental tenets of nutritionism: that food is simply the sum of its parts, that the effects of individual nutrients can be scientifically measured, that the primary purpose of eating is to maintain health, and that eating requires expert advice…Some of this reasoning turned up in Mr. Pollan's best-selling Omnivore's Dilemma. But In Defense of Food is a simpler, blunter and more pragmatic book, one that really lives up to the "manifesto" in its subtitle.

…in this slim, remarkable volume, Pollan builds a convincing case not only against that steak dinner but against the entire Western diet. Over the last half-century, Pollan argues, real food has started to disappear, replaced by processed foods designed to include nutrients. Those component parts, he says, are understood only by scientists and exploited by food marketers who thrive on introducing new products that hawk fiber, omega-3 fatty acids or whatever else happens to be in vogue…what makes Pollan's latest so engrossing is his tone: curious and patient as he explains the flaws in epidemiological studies that have buttressed nutritionism for 30 years, and entirely without condescension as he offers those prescriptions Americans so desperately crave. That's no easy feat in a book of this kind.
