WHAT YOUR FOOD ATE is the startlingly portentous title of a new study by the married team of David Montgomery and Anne Biklé, a book that takes a remarkably thorough look at how and why humans interact with food and how that food interacts with other substances. Folk wisdom declares that the dirt you inadvertently consume serves to keep you healthier; this book reveals that there’s more truth in that than you might suspect.
Montgomery, who is a professor of Geomorphology, and Biklé, a biologist, have covered these topics in their previous books, The Hidden Half of Nature, Dirt: The Erosion of Civilizations, and Growing a Revolution: Bringing Our Soil Back To Life, each of which has been reviewed on this site. But their new book not only weaves together a more complete overview of those topics, it also provides sound scientific study to support their conclusions, enough, I hope, to persuade those who might still be skeptical about the conclusions found herein.
The conclusions are simple. And profound. Our bodies have an innate nutritional wisdom. We figured out, through the trial-and-error that informs evolution, what kind of diet is needed to maintain health and fight disease. We began farming and penning animals ten thousand years ago and our bodies adapted to the dietary changes. Now, in this most modern of modern ages, we’re more likely to suffer from micronutrient malnutrition and resultant disease.
